+# Mining income per tier on igneum-testnet-1
+
+Generated by `tools/launch/income-tiers.mjs` from `tools/launch/income-tiers.json` (mission item 10, the consequences rule). Do not edit by hand: `node tools/launch/income-tiers.mjs` rewrites it and `--check` fails CI when the two disagree. Every rate and watt figure is a measurement with its source in the first table; nothing is estimated. Testnet coins have no value and the figures below say nothing about any price: the dollar columns are electricity, a cost the reader computes from a measured watt figure and a tariff they choose.
+
+## The schedule the figures use
+
+`EmissionSchedule::TESTNET_1` (the testnet genesis, decided 7 October 2026): 100 IGN a block at one block a second, a 90-day ramp from 10 percent, a monthly glide with a two-year half-life (each month pays 2^(-1/24) of the month before), then 1 percent of supply a year from about year 11.4. Of each block, 80 percent goes to the miner who found it and 20 percent to the proving pool. A miner whose key signs its checkpoints keeps the full 80 percent; an unsigned key gives a tenth of it to the proving pool.
+
+| Moment | IGN a block to the miner | Of the launch figure |
+|---|---|---|
+| day 1 | 8.00 | 10.0% |
+| day 30 | 32.00 | 40.0% |
+| day 90 (ramp over) | 75.51 | 94.4% |
+| month 12 | 58.23 | 72.8% |
+| year 2 | 41.17 | 51.5% |
+
+A solo card's expected income is its share of network hash times 86,400 blocks a day times the figure above. The tables use day 90, when the ramp is over. Before that, multiply by the ramp row; after that, by the glide row. A pool user gets the same expected amount minus the pool's fee (pool-0: 1 percent) with the variance taken out; the reference pool holds no balance and pays from the coinbase split.
+
+## The cards, measured
+
+6 October 2026, rented single-card Linux boxes (docs/analysis/prover-tiers-real-cards.md, bench log 'Prover tiers on real cards: the rented fleet, 6 October 2026'): the 0.3.12 miner on the ten-field override, the miner alone on the card, nvidia-smi power at the same second. The RX 9070 XT row is the telemetry run of 5 October 2026 on a Windows rig (bench log 'Power, heat, fans and clocks, measured'); the Apple row is the Metal bench of 4 October 2026 (site/miner-bench.json, class v4). The class v4 rates on the live devnet run lower than the ten-field rates on the same card (RTX 5090: 124.2 MH/s class v4 against 98.5 on the rented box under a different driver and container, docs/bench-log.md); the table is re-generated at the testnet cut from that class.

+Three network sizes, because income is a share of the network and nobody knows the network before it exists. 1 GH/s, 10 GH/s, 100 GH/s are reference sizes, not forecasts. The live network's estimate is on /live; divide by it.

+## Electricity a day, and the electricity cost of one mined IGN
+
+Electricity a day = measured watts x 24 h x the tariff. The cost of one IGN divides that by the day-90 figure at 10 GH/s; at another network size it scales with the network (ten times the network, ten times the cost per coin). The three tariffs: USD 0.05 a kWh is cheap industrial power, USD 0.10 is a US retail rate, USD 0.25 is a UK retail rate at today's level (each approximate; tariffs move, the watt figures do not).
+
+| Tier | Card | USD/day at 0.05/kWh | USD/day at 0.1/kWh | USD/day at 0.25/kWh | USD per IGN at 0.05/kWh | USD per IGN at 0.1/kWh | USD per IGN at 0.25/kWh |

+
+## What it means per tier, and what is being done
+
+- **One 8 GB card.** NVIDIA RTX 4060 Ti 8 GB: 19.1 MH/s at 73 W, 12,441 IGN a day at 10 GH/s after the ramp, electricity 0.174 a day at USD 0.10 a kWh. Mines; proves only core-only shards (docs/analysis/prover-tiers-real-cards.md). The record says this tier is first under power in every exit (docs/analysis/mission/past.md section 3): the glide never halves it overnight, and the card games when the income goes. Being done: the Cards screen shows the expected MH/s, W and blocks a day before the first share (mission item 6).
+- **One 12 GB card.** NVIDIA RTX 5070: 41.9 MH/s at 137 W, 27,329 IGN a day at 10 GH/s after the ramp, electricity 0.329 a day at USD 0.10 a kWh. Mines and proves beside the miner on the patched server. Being done: the same Cards line; the proving tier sentence names the shard size the card takes.
+- **One 16 GB card.** NVIDIA RTX 4060 Ti 16 GB: 17.6 MH/s at 72 W, 11,469 IGN a day at 10 GH/s after the ramp, electricity 0.174 a day at USD 0.10 a kWh. Mines and proves; the AMD row is the measured 9070 XT, 199 W for 18.6 MH/s, so per watt it is about a fifth of the NVIDIA cards of its tier and the electricity cost per coin is the highest in the table. Being done: the AMD read-width experiment (docs/plans/read-width.md); until it lands the AMD tier is told its per-watt figure before it buys.
+- **One 24 or 32 GB card.** NVIDIA RTX 5090: 98.5 MH/s at 258 W, 64,249 IGN a day at 10 GH/s after the ramp, electricity 0.620 a day at USD 0.10 a kWh. The last GPU standing in every exit on record, and the only tier that proves the full shard beside the miner. Being done: the proving pool is the second income for this tier and the Earnings screen shows shards and IGN beside blocks.
+- **A rig.** 6 x NVIDIA RTX 4070: cards times the card figure; the host's own draw is not measured and is owed. Rigs followed income across chains inside days on every chain in the record; Igneum expects no loyalty and pays staying keys a vote (30 days of blocks).
+- **A pool user.** The same expected IGN minus the pool's fee, variance removed; pool-0 holds no balance and the member's own key is in every block it finds, so a pool's vote is the member's weight. Being done: the pool finished (mission item 11).
+- **Windows, Linux, macOS.** The rates above are Linux containers (NVIDIA) and Windows (AMD); the Mac row is Metal on Apple silicon with no power reading. The same card on another operating system is within the driver's margin, not measured here: owed per platform at the testnet cut.
+
+## Owed
+
+- Intel discrete (Arc): no measurement; the tier is listed with no number until one exists
+- RTX 4060 and Apple M5 Max wall power: the rows carry the rate and no electricity column
+- every row at class v4 on the testnet cut: the rates above are the ten-field class of 6 October 2026 on rented boxes
+- a rig host's own draw: a rig row is cards times the card figure, host excluded
+
+## Check
+
+`node tools/launch/income-tiers.mjs --check` (in `tools/ci/pre-push.sh`): the file equals the generator's output. `node --test tools/launch/income-tiers.test.mjs`: the schedule arithmetic against the fork's constants (100 MH/s on 100 GH/s after the ramp = 6,912 IGN a day, the figure in docs/analysis/horizon-2026-10.md; day 1 pays 10 percent; one month step pays 97.153 percent of the one before).

+# The last mission, lane 3: the far future, 2030 to 2036
+
+Written 7 October 2026 by the future lane. Scope: the ten-year axes Horizon lane 7 did not cover, and the years 2030 to 2036 on the axes it did. Lane 7's rows to 2030 (`docs/analysis/horizon/frontier.md` 2.1 to 2.6) are taken as given and not repeated; where this lane disagrees, the row is named and the reason sourced. Every figure from memory is labelled approximate. Every figure from a source names it, with a URL in the sources list and the access date (all accessed 7 October 2026 unless stated). Times are UK. The arithmetic behind sections 2, 3, 4, 6 and 7 is `model.py` in this lane's scratch directory (`scratchpad/mission-future/`), reproduced in the tables.
+
+The design this lane tests (horizon-2026-10.md section 1): an hourly random GPU program, a 256 MiB cache over a daily multi-GB dataset (2 GiB at genesis, doubling at years 4, 12, 28), latency-shadow work in a six-rung N ladder stepped by 90 percent miner signal, class v5 (dataset from chain state) as a candidate, miner-only finality with BLS vote keys weighted by 30 days of blocks, SP1 zkEVM proving by miners (the 20 percent pool), 100 IGN a block gliding to a 1 percent tail, no stake, no dev fund, no other chain in consensus.

+| HBM on a consumer card | None announced. The Feynman datacentre architecture (2028) "supports HBM"; no consumer HBM part from NVIDIA, AMD or Intel on any roadmap found | Wikipedia Feynman page; the 2027 to 2028 rumour set | cited (absence) |
+| GDDR8 | No JEDEC standard. SK hynix's roadmap to 2031 lists "GDDR7-Next" for 2029 to 2031 | Tom's Hardware (SK hynix roadmap); TechSpot | cited |
+| GDDR7 devices | 2 GB ended at Micron (Sep 2026); 3 GB shipping at USD 60 to 70; 4 GB and 6 GB devices reported for 2027 to 2028 | chip-model-v3 5.1; wccftech; club386 | 3 GB cited, 4 and 6 GB rumour |
+| RTX 60 (Rubin GR20x) | Late 2027 slipped to 2028; GDDR7; the 6090 reported at 512-bit with 32 GB or 48 GB | TweakTown; wccftech; BigGo | rumour |
+| AMD RDNA 5 / UDNA | Mid-2027 to 2028; GDDR7 at 36 Gbps; flagship "AT0" 154 CUs, 36 GB on 384-bit, 1.7 TB/s, 380 W; shares a chiplet design with the next Xbox; GDDR7 support landed in the Linux driver | TweakTown; TechPowerUp; Tom's Hardware driver note | rumour, driver patch cited |
+| NVIDIA consumer chiplets | Nothing reported; Rubin consumer parts described as monolithic | the same rumour set | approximate |
+| Strix Halo class | Strix Halo: 256-bit LPDDR5X-8000, 256 GB/s. Medusa Halo (2027 to 2028): LPDDR6 on 256-bit (461 GB/s) or 384-bit (691 GB/s) | VideoCardz; hardware-corner.net | rumour |
+| Apple | M5 Max: up to 128 GB unified, 614 GB/s (40-core GPU), 460 GB/s (32-core); M5 Ultra Mac Studio August 2026 | Apple newsroom 3 Mar 2026 and Aug 2026 | cited |
+| LPDDR6 | JESD209-6 published July 2025; 2 sub-channels a die, 12 DQ each, 4 CA each; activate timings not public | JEDEC press release | cited; timings unknown |
+| DDR5 | 32 banks in 8 groups of 4 (x4/x8); JESD79-5D Nov 2025; tFAW a four-activate window | JEDEC; DDR5 core datasheet | cited |
+| The latency floor | "The latencies of three fundamental DRAM operations have not improved significantly in the past 18 years"; improvements "relatively stagnant for the last two decades" | Lee et al. (arXiv 1604.08041); Chang et al. (arXiv 1805.03154) | cited |
+
+### 1.2 What it means for the memory-latency-bound hash
+
+The hash advances one dependent 4-byte read per memory latency; the rate is activates per tFAW window times channels, and energy is per activate (chip-model-v3 5.3). Pin speed does not move it. So the ten-year question is only: do channels per watt per dollar move, and does tRC or tFAW move. The sources say tRC has been flat for about twenty years, and no DRAM roadmap to 2031 (SK hynix) names a row-cycle improvement. HBM4 doubles channels per stack (lane 7, 2.3). HBM4E adds pin speed and a custom base die, not channels. GDDR7-Next is 2029 to 2031 and unspecified. Consumer HBM does not exist on any roadmap to 2028.
+
+| Year | Flagship consumer memory (projected) | Random reads per second, flagship (approximate) | Mid-tier card (12 to 16 GB) | Tier that wins or loses against 2026 |
+|---|---|---|---|---|
+| 2026 | 32 GB GDDR7, 512-bit, 16 devices | 17.5 G measured (5090) | 12 GB, 192-bit, 6 devices: about 6.5 G | baseline |
+| 2028 | 36 to 48 GB GDDR7, 384 to 512-bit (RDNA 5 rumour, RTX 60 rumour) | 16 to 21 G: the same, capacity adds no channels | 16 to 18 GB on the same channel count (3 GB devices): the same rate | nobody: a 2026 card keeps its rate against a 2028 card |
+| 2031 | 48 to 64 GB GDDR7-Next (SK hynix window) | unknown; if channels per device rise to 8 (approximate guess), 1.5 to 2x | 24 GB mid-tier on the same count | the 2026 owner falls to 0.5 to 0.7x of the new card, the normal GPU cadence |
+| 2036 | 64 to 96 GB (extrapolation of lane 7's 1.167 a year); HBM on a halo consumer part possible but unannounced | 2 to 4x of 2026 if a consumer HBM4-class part ships; otherwise 1.5 to 2x | 32 GB mid-tier | the 8 and 12 GB tiers are gone from the installed base (Steam trend, algorithm.md 5.6), not from the hash |
+
+Apple and APUs: the M5 Max's 614 GB/s is a 512-bit LPDDR5X bus (approximate); LPDDR activates are the same DRAM physics, so the Apple tier stays "0.78 uJ per hash, 21 W" class (algorithm.md 5.3a), the best per joule and the worst per dollar (USD 129 per MH/s). Medusa Halo on 384-bit LPDDR6 would be a 24 to 36 channel part (approximate: 2 sub-channels a die): a mid-tier card's read rate at laptop watts. Consequence per tier: Apple and APU miners stay the per-joule leaders and never the per-dollar ones; nothing in the hash changes that in ten years.
+
+### 1.3 The cache, the dataset schedule and the ladder, re-read against the roadmap
+
+| Design item | Roadmap fact | Verdict | Recommendation |
+|---|---|---|---|
+| 256 MiB cache "above every GPU's on-die cache" (the spec's rule) | 5090 L2 96 MB, GB202 128 MB; MI300X carries 256 MB Infinity Cache (datacentre, approximate from memory); RDNA 3's 7900 XTX 96 MB; no consumer part at 256 MB announced | Safe to 2028. At risk from 2029 to 2031 if a consumer part ships a 256 MB last-level cache, which the datacentre already does | Add a cache-size rung to the era-draw ladder beside N (256 to 512 MiB), stepped by the same 90 percent signal, in place of the fixed year-4 doubling alone; the trigger is a shipped consumer part with LLC at or over the cache size |
+| Dataset 2 GiB, doubling at years 4, 12, 28 | Card memory 32 GB now, 48 to 64 GB by 2030 (lane 7); one HBM3 stack holds 24 GB | Right. The dataset is not a lever against the stored-dataset chip (chip-model-v3 5.7) and never binds a tier before year 12 (algorithm.md 5.6) | Hold the schedule; the public card-lifetime sentence should carry the prover footprint, not the dataset (algorithm.md 5.6's one change) |
+| N ladder rungs measured on 2026 cards | The honest card's bind point moves with each generation: a 2028 card with the same read rate and 1.5x the ALUs binds at a higher N; HBM4 doubles the chip's rate per stack | Rungs are a 2026 measurement. They are the right shape and the wrong numbers for 2029 | Re-measure the rungs per card generation (the Steam top-10 cards each era) and publish the bind points; the signal mechanism already lets miners refuse a rung their cards cannot hold, so no genesis change, only a measurement duty written into the era-draw docs |

+
+Emission by year from the model (IGN, approximate): year 1 2.32 B, year 2 1.87 B, year 3 1.31 B, year 4 0.92 B, year 5 0.65 B, year 6 0.46 B, year 7 0.32 B, year 8 0.23 B, year 9 0.16 B, year 10 0.11 B; supply 4.18 B at the end of year 2, 7.07 B at year 5, 8.33 B at year 10.
+
+### 2.2 The decision tree, written out
+
+The maker chooses a target share s of the hash and a node. Revenue over the chip's two-year life is s x E2 x p, where E2 is the two-year emission and p the IGN price. The fleet needed is s/(1 - s) x H(p), and at the rental equilibrium H(p) = 7.8 M MH/s per USD of price, so the fleet's cost is also linear in p: 0.43 x 7.8 M x USD 4.64 per MH/s (the chip's two-year cost per MH/s with power at USD 0.05 per kWh, model) against two-year revenue per MH/s of 0.0117 x 17,520 = USD 205. The fleet term is 2 percent of revenue and drops out. The project pays when p is over p* = C_proj / (s x E2), and the market cap at which it pays is p* x supply. At s = 0.30 (an economic miner just under the veto third):
+
+| Node (project all-in) | Years 1 to 2 (E2 = 4.18 B) | Years 3 to 4 (2.24 B) | Years 5 to 6 (1.10 B) | Years 7 to 8 (0.55 B) | Years 9 to 10 (0.27 B) |
+|---|---|---|---|---|---|
+| 28 nm controller only, no shadow core (USD 5 M) | p* 0.0040, cap USD 17 M | 0.0075, 48 M | 0.0151, 114 M | 0.0306, 247 M | 0.0620, 517 M |
+| 28 nm controller + N5 shadow core (USD 30 M) | 0.0239, 100 M | 0.0447, 287 M | 0.0906, 682 M | 0.1836, 1,481 M | 0.3718, 3,099 M |
+| N3 single die, controller + shadow + lanes (USD 60 M) | 0.0478, 200 M | 0.0895, 574 M | 0.1813, 1,363 M | 0.3672, 2,961 M | 0.7437, 6,198 M |
+| N2 (USD 150 M, 2026 quotes) | 0.1195, 500 M | 0.2237, 1,436 M | 0.4532, 3,408 M | 0.9179, 7,403 M | 1.8592, 15,495 M |
+| A16 / A14 (USD 250 M, extrapolated) | 0.1992, 833 M | 0.3729, 2,393 M | 0.7553, 5,680 M | 1.5298, 12,339 M | 3.0987, 25,825 M |
+
+Reading. The stored-dataset chip without a shadow core pays at a USD 17 M market cap in the first two years, because its project is a 28 nm controller (chip-model-v3 5.6) and the chip's hour costs 56x less than rented hash. The class v4 shadow core forces an N5-class die (30 mm^2 at N = 100,000, lane 7) and lifts the bar 6x to USD 100 M. The glide lifts every bar about 2.3x per two years, so by years 9 to 10 the same N5 chip needs a USD 3.1 B cap. Nothing here needs N2 or A16: the chip is memory, and a leading node buys it nothing. So the "ASIC maker's economics at every node" collapses to two nodes, 28 nm and N5, and the N ladder is what moves between them.
+
+Minimum volume to break even against buying cards (saving USD 2,131 a chip over two years against 5090s at the same hash, model): 28 nm bare 2,346 chips (0.39 TH/s); 28 nm + N5 shadow 14,077 chips (2.34 TH/s); N3 28,155 (4.67 TH/s); N2 70,387 (11.7 TH/s); A14 117,312 (19.5 TH/s). Against the rental-equilibrium hash (39 to 780 GH/s at today's three price inputs) the 2.34 TH/s break-even fleet is 3x to 60x the whole network: the chip only pays once the price is high enough for the network to be a few TH/s, which is the p* column above said another way.
+
+### 2.3 The memory-controller chip against HBM4, per joule and per dollar, 2026 to 2036
+
+| Year | Memory the chip buys | Chip uJ per hash at N = 100,000, k = 1 (approximate) | Honest 5090-class uJ | Edge per joule | Chip USD per MH/s | What moves it |
+|---|---|---|---|---|---|---|
+| 2026 | GDDR7, 16 x 2 GB | 1.37 | 3.27 | 2.4x | 2.8 | the measured row (algorithm.md 5.3a: 2.1x at the 5090's 431 W cap) |
+| 2028 | HBM4, one stack 36 GB, C-HBM4E base die as the controller | 1.33 (algorithm lane's correction of lane 7's 1.11) | 3.3 (a 2028 card at the same read rate) | 2.5x | 2.0 to 2.5 (the interposer and controller rows fall into the base die; approximate) | HBM4 price USD 550 a stack falls as HBM4E takes the premium (approximate) |
+| 2031 | HBM4E or HBM5 (SK hynix lists HBM5 on the 2029 to 2031 window) | 1.2 to 1.3 at the same N; 0.9 at N = 100,000 if activates per channel double again | 3.0 to 3.3 | 2.5x to 3.5x | 1.5 to 2.0 | activate parallelism per stack; unsourced beyond HBM4 |
+| 2036 | the same class | the per-joule edge is bounded below by N x 11 pJ x k, so at N = 330,000 and k = 1 the chip pays 3.6 uJ of program work whatever its memory | 5.0 at 330,000 (the 5090 is compute-bound there) | 1.3x | 1.5 | N and k only |
+
+Does the chip get cheaper or dearer per joule as HBM prices fall: dearer in dollars relative to the GPU through 2027 (lane 7 2.2, memory is 70 percent of its bill), cheaper from 2028 when the base die absorbs the controller, and flat per joule, because per joule is set by activates and by N. Per tier: the home 5090 owner stays inside 2.1x to 2.5x of the chip at N = 100,000 through 2031 and inside 1.3x at N = 330,000; the 4070-class 12 GB owner the same within 10 percent; the AMD 9070 XT owner sits at 5x to 8x behind the chip at every rung (its measured 10.6 uJ) and is the first tier a chip displaces; the Apple tier sits under the chip's per-joule line at every rung. The rig owner is a 5090 owner times eight. The pool user inherits the pool's card mix.
+
+### 2.4 The FPGA route
+
+AWS F2 (f2.6xlarge, VU47P, 16 GB HBM2, USD 1.98 an hour on demand, USD 0.66 spot) is the measurement the algorithm lane planned (algorithm.md 5.1); nothing has run. The tightened range stands: 2.3 to 2.9 G reads a second a card, 0.30x to 0.47x of the 5090 per watt, at USD 4,000 to 5,000 a card (approximate). Versal HBM and Agilex 7 M-series carry HBM2e (faster pins, the same tFAW), so they sit in the same row. An HBM4-based FPGA (none announced) would carry HBM4's channel count and the 0.3x to 0.5x row would become 0.6x to 1.0x (approximate, derived). Verdict: no FPGA displaces any tier to 2031; the F2 hour should still run, because the per-stack activate rate it measures is the input every row above rests on.
+
+Recommendation for section 2: (1) the N ladder at genesis, as lane 2 and lane 7 said, with the bind-point re-measurement duty of 1.3; (2) write the p* table into the public threat model with the sentence "a stored-dataset chip pays at about USD 100 M of market cap in year 1 and about USD 700 M in year 5 (model, approximate)"; (3) no genesis parameter changes for N2 or A16, because the chip never needs them.

+
+### 3.2 The used-GPU flood, 2027 to 2030
+
+Hopper fleets bought in 2023 to 2024 reach the 36-month residual cliff in 2026 to 2027 and the 60-month floor in 2028 to 2029. Can they mine Igneum: the hash is memory-latency-bound, so an H100 is its five HBM3 stacks (80 GB) and an A100 its five HBM2e stacks. At chip-model-v3's unmeasured HBM3 ceiling (10.7 G reads a second a stack) an H100 reads 53 G, 3x a 5090; at the JEDEC tFAW ceiling (2.3 G a stack) 11.5 G, 0.65x. Nobody has measured it; the fleet measured A4000, A5000, L4, 3090 and 4090 (prover-tiers-real-cards.md), not an HBM part. The honest statement: an H100 mines Igneum at 0.65x to 3x of a 5090 at 700 W, which is 0.3x to 1.4x per watt (approximate, both ends unmeasured).
+
+| Scenario | Hash it adds | Against the rental equilibrium (39 to 780 GH/s) | What the ladder does |
+|---|---|---|---|
+| 1 percent of a 1 M retired H100 fleet (10,000 cards) at 1x a 5090 | 1.3 TH/s | 2x to 35x the whole network | nothing: the shadow binds compute, and an H100 has 4x a 5090's ALUs per read; it holds every rung |
+| 10 percent | 13 TH/s | 17x to 330x | the same |
+| Rental at USD 1.49 an hour for 0.65x to 3x of a 5090 | USD 0.0045 to 0.021 per MH/s-hour | at or above today's 0.0117: no cheaper than consumer pods at list price | n/a |
+| Idle-time rental (the owner's marginal cost is power) | USD 0.00016 to 0.0007 per MH/s-hour at USD 0.05 per kWh | 17x to 70x under today's rent | n/a |
+
+The ladder is a joule argument against a fixed-datapath chip; against a GPU with more ALUs it is silent. The used-fleet question is a price question only.
+
+### 3.3 The ten-year rental curve and the 51 percent table
+
+The H100 rate fell about 45 percent a year from early 2024 to 2026 (USD 7+ to about 2); consumer-card rent fell as purchase prices rose (lane 7 2.4). Three curves for USD per MH/s-hour from today's 0.0117 (model):
+
+| Year | At -20 percent a year | At -30 percent a year | At -45 percent a year |
+|---|---|---|---|
+| 2028 | 0.0075 | 0.0057 | 0.0035 |
+| 2031 | 0.0038 | 0.0020 | 0.0006 |
+| 2036 | 0.0013 | 0.0003 | 0.00003 |
+
+What it does to `51-percent.md`: nothing to the dollar cost of any attack, because every row there is priced at the rental equilibrium, where rent equals subsidy. A cheaper rent means more hash joins until rent equals subsidy again: at 2036's -30 percent curve the equilibrium hash is 35x today's at the same IGN price, and the attack costs the same twelve days of emission. What the curve changes is the home card's share of the subsidy, which falls 35x with the hash, and the supply ceiling of the rental market, which stays the real limit (the market gave zero pods when asked for twenty, bench-log). Update the 51-percent price basis each year from a measured rental, not from a curve.
+
+### 3.4 Per tier: does a home card stay competitive against an idle datacentre card
+
+Cost per MH/s-hour, electricity only, a 5090-class card at 3.27 uJ (model):
+
+| Owner and power price | USD per MH/s-hour | Margin under today's 0.0117 rent | Margin if idle datacentre hash sets the rent (0.00016) |
+|---|---|---|---|
+| UK home, 26.32 p (Ofgem cap, Q4 2026) | 0.00114 | 10x | loses 7x |
+| Germany home, EUR 0.387 | 0.00137 | 9x | loses 9x |
+| US home, 17.7 c (EIA, H2 2025) | 0.00058 | 20x | loses 4x |
+| Texas industrial, 5 c (approximate) | 0.00016 | 72x | break-even |
+| Paraguay, 4.4 to 6 c (ANDE crypto tariff, Decree 7824/2022, contracts end 31 Dec 2027) | 0.00016 | 72x | break-even |
+| Iran, licensed, about 1 c | 0.00003 | 358x | wins |
+
+The home card is competitive while the marginal supplier of hash is a rented consumer pod at list price (today). It is not competitive the day the marginal supplier is an idle datacentre card on industrial power, and the used-fleet flood of 3.2 makes that day a price event, not a technology event. Per tier: 8 and 12 GB home cards lose first (their uJ is 1.3 to 1.7x worse than the 5090's); 24 and 32 GB cards last; a rig is a home card eight times, on the same power price; a pool user's payout tracks the pool's share, which falls with the home share; Windows and Linux are the same; macOS at 0.78 uJ (M5 Max) holds a 4x power edge over the 5090 and loses last of all the home tiers; NVIDIA and AMD as their uJ rows (algorithm.md 5.3a); Apple as macOS.
+
+What Igneum should do: the reward rule that prices rented hash out (lane 7's 3.1, weight-aged keys paid more) is the only lever in the protocol; the earnings page should show the miner's own cost per MH/s-hour against the network's implied rent, so a UK miner sees the day the line crosses; and the H100 and A100 random-read rate should be measured on one rented card this month (two hours, under the measure lock), because every row of 3.2 rests on it.

+

+
+The economics per kWh (model): a 5090 at the 431 W cap is a 0.43 kW heater. Credit the heat at the gas price delivered through a 90 percent boiler, or at a heat pump's electricity (COP 3):
+
+| Region | Electricity | Heat credit, gas | Heat credit, heat pump | Effective price in the heating season |
+|---|---|---|---|---|
+| UK | 26.3 p | 7.0 p (27 percent) | 8.8 p (33 percent) | 17.5 to 19.3 p |
+| Germany | 38.7 c | 13.3 c (34 percent) | 12.9 c (33 percent) | 25.4 to 25.8 c |
+| US | 17.7 c | 5.6 c (31 percent) | 5.9 c (33 percent) | 11.8 to 12.1 c |
+
+A third off the power bill for the 1,500 to 2,000 heating hours a year (approximate), everywhere. It moves a UK home miner from 7x to 5x the Texas industrial price, not to parity. Consequence per tier: it matters most to the tiers with the worst uJ (8 and 12 GB, AMD) and least to Apple (21 W is not a heater). Recommendation: a heat mode in Ember (run the miner only while a room thermostat or schedule calls, power cap set to the room's load, the hourly program unchanged), which costs nothing in protocol and is the one feature home-mining heaters ship.
+
+### 4.3 Grid balancing
+
+ERCOT paid Riot USD 31.7 M in August 2023 (24.2 M curtailment credits plus 7.4 M demand response) and Riot booked USD 30.6 M of power-curtailment credits in Q3 2025, up 147 percent on the year (ABC13; Riot releases). The programmes name "large flexible customers"; a home GPU is not one. Home aggregators exist (the UK's supplier demand-flexibility sessions, US utility programmes; approximate, from memory) and pay per kWh shed against a baseline. A fleet of Ember miners is a shed-able load only if a signal reaches it. Recommendation: a curtailment input in Ember (a webhook, a schedule, a price threshold from a public spot feed) that pauses the miner and resumes it; the protocol sees a key that stops voting for an hour, which the LEAVE item of 0.3.16 already prices as nothing (vote-or-burn.md: no burn). Per tier: a pool user's pool must pass the signal down; a rig is the only home tier big enough to enrol directly.

+
+### 5.2 The trend line to 2036 and the 20 percent pool
+
+Lane 7's 33x a year is software catching hardware and cannot hold. Hardware alone is 1.5x a year. The EF's own 2026 metric is kWh a proof, which is the right axis for a miner-prover: a shard that costs a joule of GPU time is paid from the pool and competes with the same joule in the lottery.
+
+| Year | Block proof cost on the open market (USD, approximate) | Hardware that proves an Ethereum block in real time | What proves an Igneum shard (4.7 M cycles) under 10 s | Does a home 12 GB card have a place |
+|---|---|---|---|---|
+| 2026 | 0.005 to 0.02 | 16 x 5090 (SP1), 4 x 5090 (ZisK) | 5090 beside its miner (10.7 s), every card alone | yes, alone or hand-off (prover-tiers-real-cards.md) |
+| 2028 | 0.001 to 0.005 | 1 to 4 consumer cards; first ASIC or VPU boards if any ship (none has) | every card from the 3060 at 3x a year (lane 7's table); 12 GB beside the miner at 3x, not at 1.5x | yes alone; beside the miner only under 3x |
+| 2031 | 0.0003 to 0.001 | one consumer card, or a prover ASIC at 10 to 50x per joule if the claims land | a 12 GB card in 1 to 3 s | yes, but a prover ASIC would take the external job market first (dollar-priced jobs go to the cheapest joule), and the pool second only if shards are open to anyone |
+| 2036 | under 0.0001 | commodity | any card | the pool's economics are the lottery's: whoever holds vote weight is drawn (sortition by weight), so the home card keeps its share of the pool whatever an ASIC does to the open market |
+
+The design's defence is already in place: the pool is drawn by vote weight (sortition), and vote weight is 30 days of blocks, which a prover ASIC does not have. A prover ASIC centralises the external job market, not the pool. What it would do to the pool is set the shard deadline: if the chain tightens the deadline toward ASIC times, home cards miss it. So the shard deadline must be a function of the measured fleet median (lane 7's rule), re-read each era, and the shard size must stay at a size a 12 GB card proves alone inside it (today 4.8 to 14.4 s). "Verified proving as the reward" (horizon-2026-10 item 1: the proof verified in consensus) is the piece that makes the pool unforgeable, and its activation is the decision owed.
+
+Per tier: 8 GB (proves alone, never beside its miner; keeps its pool share by weight); 12 GB (the swing tier; the hand-off profile is the product); 16 GB and up (unconstrained); rig (proves beside mining on every card from 2028 at 1.5x); pool user (the pool operator's prover does it); Windows, Linux (the same); macOS (an M5 Max proves a shard, unmeasured against the rented table; Metal lane open); NVIDIA (every measurement is NVIDIA); AMD (no measured shard time; the 9070 XT has no SP1 GPU backend measured here, so the AMD tier proves on CPU or not at all until it is measured, which is the first owed number); Apple (as macOS).
+
+### 5.3 Proof-system risk and the swap interface
+
+| Event | Date | What a malicious prover could do | Source |
+|---|---|---|---|
+| SP1 v3.4.0 (LambdaClass, 3MI, Aligned) | disclosed 26 Jan 2025 | "generate valid SP1 proofs of incorrect execution of an arbitrary program": universal forgery, from two bugs plus a Plonky3 evaluation gap | LambdaClass blog; Blockworks |
+| RISC Zero zkVM 2.0.0 to 2.0.2 | 15 May 2025 | a missing constraint in the rv32im circuit let any 3-register instruction be proven wrong; on-chain verifiers stopped by estop | HackenProof |
+| SP1 Hypercube JALR | 20 May 2026 | a completeness bug (prover crash), not soundness; the EF's audit found only 51 of 62 opcodes fully proven, four load instructions proven against wrong specifications | zkevm.ethereum.foundation |
+
+Three soundness-class events in 18 months across the two leading zkVMs. On Igneum today a soundness bug is a light-client problem (spec 10.1; finality-in-proof.md 4.4): every full node executes natively and vetoes a record whose statement differs. It becomes a chain failure the day any of three things is true: (1) proof verification in consensus pays a shard on the proof alone (the 0.3.16 switch) and a forged proof carries a correct statement, which earns the pool and nothing else; (2) finality is carried inside the proof (lane 7's 3.3) and a forged proof carries a forged weight table, which a full node still vetoes, so the failure is confined to proof-only clients; (3) the chain ever lets a proof replace execution for full nodes, which the design forbids. So the chain-failure case is (3), and the rule is: never. The swap interface needs: a pinned verifier key per proof system with a version in the record; two independent zkVMs accepted in parallel (the EF's own "multiple provers" lesson), with a record valid only if its system is on the active list; a 95 percent class-change signal to retire a system, and a stop switch (RISC Zero's estop pattern) that any 1/3 of weight can flip to "execution only" inside an hour. Per tier: nothing a miner does; a pool's prover must build for two systems; the cost is two guest builds and two verifier keys.

+## 6. Light clients on phones, 2026 to 2036
+
+### 6.1 The state of the art
+
+| Client | What it verifies | Bytes and time | Source |
+|---|---|---|---|
+| Ethereum sync-committee clients (Helios, Kevlar) | 512-validator sync committee signatures; syncs in about 2 s, no storage; "lightweight enough to run on mobile" | about 25 KB per two days (24,576 bytes of keys plus the signature, header and branch) | a16z Helios; annotated spec |
+| Mina | a recursive SNARK of the whole chain | a 22 KB chain; "a few milliseconds of processing" | Mina docs via gate.com, iq.wiki |
+| Celestia Lumina | data-availability sampling in a browser or phone (Wasm, Rust) | random shares a block; bandwidth not published for 2026 (approximate: tens of MB a day) | celestiaorg/lumina; Eiger |
+| Bitcoin BIP-157/158 (Neutrino: Breez, Blixt) | compact block filters served by full nodes | headers and filters in under 5 minutes | Blixt; Lightning Labs |
+| StarkWare's Bitcoin header proof | every header since genesis in one STARK | 1 MB, under 100 ms on a phone | cryptotimes 11 Sep 2025 |
+| Zcash (Zashi/Zodl SDKs, lightwalletd; Tachyon-Lite) | shielded sync through servers | server-dependent (the anti-pattern) | Zcash forum, GitHub |
+| Kaspa wallets (Kaspium, kaspa-core) | none: wallets talk to public nodes over wRPC | n/a (approximate) | coincodex; Zelcore |
+| Phone verify times | Groth16 about 5 ms; a Keccak circuit's verify 0.12 s on an iPhone 15 Pro (Mopro); a 45 KB STARK in 16 ms (laptop, approximate); Groth16 proving 2.9 to 3.1 s on a Galaxy S25 and iPhone 17 Pro | Mopro benchmarks; provebench; shattered.io | cited, mixed devices |
+| WebGPU | in Chrome 113, Edge 113, Safari 18, Firefox 141 | n/a | Wikipedia WebGPU |
+
+### 6.2 What Igneum's finality-in-proof needs from the phone
+
+The client holds one proof and fetches the newest segment proof from any node (finality-in-proof.md 4.2); SP1's compressed verify is 0.032 s on a Mac core (bench-log 5 Oct), a Groth16 or Plonk wrapper is unmeasured. Model (a wallet updating every 10 minutes, 144 times a day, a phone big core at 3 W, LTE at about 1.5 J a MB, an 18 Wh battery):
+
+| Form the wallet verifies | Bytes a day | CPU | Radio | Battery a day |
+|---|---|---|---|---|
+| Groth16 or Plonk wrapper (about 1 KB with public values) at about 10 ms on a phone (approximate, 3x the Mac core) | 0.14 MB | 4 J | under 1 J | 0.007 percent |
+| Compressed STARK at the EF's 300 KiB ceiling, about 100 ms on a phone | 42 MB | 43 J | 63 J | 0.16 percent |
+
+Either is nothing. The choice is the EF's: no trusted setup and under 300 KiB, which is the STARK row, and by 2030 a WASM-SIMD or WebGPU verifier on a phone should put the STARK verify under 30 ms (approximate projection from the 294x STARK-verifier speedup reported in 2026 and the WebGPU adoption row). The 2026 answer is the Plonk wrapper (no trusted setup, small) for the phone and the compressed STARK for nodes. Bytes a day are set by update frequency, and a wallet that updates on open rather than on a timer is under 1 MB a day in either form.
+
+"Every miner is also a light-client server" has prior art: Bitcoin full nodes serving BIP-157 filters under the NODE_COMPACT_FILTERS service bit (every full node that opts in serves every light client), and Ethereum's Portal Network (every node serves a slice; "without having to trust or put extra strain on full nodes"). The anti-pattern is Zcash's lightwalletd, a few servers everyone trusts. Recommendation: the node serves `igneum_getSegmentProofBytes` over p2p and a rate-limited HTTP path, on by default in Ember, so the serving set is the miner set; the phone client dials three miners and takes the longest valid chain of proofs. Per tier: no cost a miner notices (one proof of a few hundred KB served on request); the pool node serves for its members; Windows, Linux, macOS, every vendor the same.

+## 7. Post-quantum signatures and a proof-of-work chain
+
+### 7.1 The standards and sizes
+
+| Scheme | Standard | Public key | Signature | Status | Source |
+|---|---|---|---|---|---|
+| ML-DSA-44 | FIPS 204 | 1,312 B | 2,420 B | final (Aug 2024) | Cloudflare 9 Jul 2026; FIPS 204 |
+| ML-DSA-65 | FIPS 204 | 1,952 B | 3,309 B | final | encryptionconsulting |

+| SLH-DSA-SHA2-128s / 128f | FIPS 205 | 32 B | 7,856 B / 17,088 B | final | Cloudflare |
+| FN-DSA-512 (Falcon) | FIPS 206 | 897 B | 666 B | draft; final expected late 2026 to early 2027; floating-point signing is "difficult to implement securely" | encryptionconsulting; Cloudflare |
+| ML-KEM | FIPS 203 | n/a | n/a | final | NIST |
+| BLS12-381 (today) | n/a | 48 B | 48 B aggregate for 8,192 voters | quantum-broken by Shor on the curve's discrete log | ethereum.org PQ page |
+
+Timelines: NIST IR 8547 deprecates ECDSA, EdDSA, RSA and EC Diffie-Hellman after 2030 and disallows them after 2035 (final version confirmed). The Global Risk Institute's 2025 survey (26 experts, report page dated 9 Mar 2026): a cryptographically relevant quantum computer "quite possible (28 to 49 percent)" within 10 years and "likely (51 to 70 percent)" within 15. Resource estimates: ECC-256 at 1,200 to 1,450 logical qubits and 70 to 90 M Toffoli (Google, 2026), about 500,000 physical qubits against about 1 M for RSA-2048 (Gidney, May 2025); 835 logical qubits with 2^30.6 Toffoli (Luo et al., arXiv 2607.13816, Jul 2026). Bitcoin: BIP-360 merged into the BIPs repository 11 Feb 2026 as a draft (P2MR, formerly P2QRH), a companion BIP for ML-DSA and SLH-DSA, a testnet implementation March 2026, no activation. Ethereum: a PQ team formed January 2026; BLS to be replaced by leanXMSS (hash-based) with leanVM aggregating "3,000 bytes" of signature against BLS's 96 by "250x"; core PQ infrastructure targeted "by approximately 2029"; EIP-8141 account abstraction for user migration.
+
+### 7.2 What quantum does to Igneum
+
+| Component | Break | Consequence | Size of the fix |
+|---|---|---|---|
+| BLS vote keys (in every header) | Shor on BLS12-381's G1 discrete log (a 255-bit subgroup over a 381-bit field; wider than secp256k1, so a later break by a year or two, approximate) | every vote key is public; a CRQC forges two thirds of weight and certifies any chain. Catastrophic | the migration below |
+| Hash-to-curve | none; it is a hash | nothing | nothing |
+| ECDSA accounts in the EVM | as Ethereum: exposed public keys after a first spend | user funds; the same exposure as Ethereum's "0.1 percent dormant" row, smaller | account abstraction with an ML-DSA verify precompile from genesis |
+| The VRF (aggregator pick) | if EC-based, forgeable; aggregation is not safety (every voter signs) | liveness nuisance | the same key succession |
+| The class-group VDF (epoch seed, era draw) | Shor computes the class-group order, which removes the sequentiality assumption of a Wesolowski-style VDF (approximate; from memory of the class-group VDF literature) | an attacker with a CRQC grinds the hourly program seed | a hash-chain fallback behind the same version byte; flagged, not sized |
+| SP1 (STARK core, Groth16/Plonk wrapper) | the STARK is hash-based and stands; the pairing wrapper falls | the on-chain and phone verifier moves to the compressed STARK | the wrapper choice of section 6 |
+
+### 7.3 The cost in bytes, 8,192 voters, every voter signing every 30-second checkpoint (model)
+
+| Scheme | Per checkpoint | Per day (2,880 checkpoints) | Averaged per block at 1 block/s | Key in the header |
+|---|---|---|---|---|
+| BLS aggregate (today) | 1.0 KB (48 B + a 1,024 B bitmap) | 2.9 MB | 34 B | 48 B |
+| ML-DSA-44 | 19,361 KB | 57.1 GB | 645 KB | 1,312 B |
+| ML-DSA-65 | 26,473 KB | 78.1 GB | 882 KB | 1,952 B |
+| FN-DSA-512 | 5,329 KB | 15.7 GB | 178 KB | 897 B |
+| SLH-DSA-128s | 62,849 KB | 185 GB | 2,095 KB | 32 B |
+| SLH-DSA-128f | 136,705 KB | 403 GB | 4,557 KB | 32 B |
+| ML-DSA-44 aggregated by a SNARK at the EF's 250x | 77 KB | 223 MB | 2.6 KB | 1,312 B, or a 32 B hash of it |
+
+A naive ML-DSA swap costs 57 GB a day of votes against a block stream of about 100 MB a day (approximate), 500x. It is not shippable without aggregation. The aggregator already exists in the design (VRF picks 8 aggregators a checkpoint): the migration is "aggregators carry a STARK of N verified PQ signatures", which is Ethereum's leanVM shape, and the per-checkpoint cost falls to the order of 100 KB.
+
+### 7.4 The plan to pre-commit at genesis
+
+1. A `sig_scheme` version byte in the vote item and in the vote-key registration; genesis value 0 = BLS12-381.
+2. Key succession at registration: every vote key registers with a 32-byte hash of a successor public key (any scheme). A `succeed` item signed by the old key and the new key moves the 30-day weight to the successor without a reset. Miners generate the successor at first run; Ember stores it offline.
+3. A PQ verify precompile (ML-DSA-44 first, FN-DSA when FIPS 206 is final) in the EVM from genesis, so account abstraction can migrate users before 2030.
+4. The flip is a class change: 95 percent signal with a floor height, as the P2 mechanism; the aggregated-vote format ships first, the scheme flip second.
+5. The VDF carries the same version byte with a hash-chain fallback.
+6. The public sentence: "Igneum's vote keys and accounts can move to NIST post-quantum signatures by miner signal; the key succession is in every key from genesis."
+
+Per tier at migration: a home miner on any card runs the updater and signs one `succeed` item from Ember; ML-DSA-44 signing is well under a millisecond on any CPU (approximate), every 30 s; the bandwidth cost is the aggregated form's, about 100 KB a checkpoint, which an 8 GB card's host handles; a rig's one key succeeds once; a pool's key is the operator's, and pool members do nothing; Windows, Linux, macOS, NVIDIA, AMD, Apple: nothing hardware-specific, since the signature runs on the CPU.

+### 8.3 What Igneum writes into its genesis and public text now (not legal advice; counsel is engaged)
+
+1. No issuer, no offeror, no sale: every coin is created as a block reward (MiCA Article 4(3)(b) language, verbatim in the litepaper).
+2. The 2025/422 sustainability indicators (kWh a year from hash rate and measured uJ, intensity per transaction, mix by region when known) published by the project each era, so an EU CASP can list without asking.
+3. No financial promotion: no price, no "buy", no "invest", no return language anywhere the UK can read it; the earnings page shows hash and IGN, not sterling.
+4. The pool reference implementation never holds a member's balance: payouts are direct from the coinbase split (the pool is a coordinator, not a custodian), which keeps pools out of CASP, safeguarding and VASP shapes in every regime above.
+5. The job market is peer-to-peer settled on-chain; no operator account, no dollar leg in the protocol; the dollar price is a quote, the settlement is IGN.
+6. The software is published under an open licence by a company that holds no coins by right (no dev fund, already decided) and runs no service the chain depends on.
+7. The region prompt and the banned-region list in Ember (Russia's ten regions and Moscow from 15 Aug 2026, China) with the sentence "mining may be restricted where you are; you are responsible for checking".
+8. A genesis "no privileged key" statement: no key can mint, pause or upgrade (true by design; say it because the regulators' tests turn on it).
+
+## 9. Ten-year scenario table
+
+| Year | Scenario A: GPUs stay general and cheap | Scenario B: HBM-only high end, APU-only low end | Scenario C: proving ASICs win |
+|---|---|---|---|
+| 2028 | 48 GB flagship on GDDR7 (lane 7); used H100s at USD 7,500 to 10,500 flood rentals; hash at the rental equilibrium, home share falling with the rent curve. Igneum: the N ladder's first rung by signal; home miners inside 2.5x of the chip per joule; the chip pays at USD 100 M of cap. Alive. The parameter: N stepped by signal | HBM4 only on datacentre parts; consumer GDDR7 unchanged; APUs (Medusa Halo, M6) take the laptop tier. Igneum: nothing changes for the hash; the Apple and APU tiers grow. Alive. The parameter: the cache rung, in case an APU's LLC reaches 256 MB | First VPU or C1 boards ship at 10 to 50x per joule on MSM and NTT; the external job market goes to them within a year. Igneum: the 20 percent pool is sortition by weight, so home cards keep it; the dollar market is lost to ASICs. Alive, with the external income line (already "never the main income" by 2030, lane 7 3.11) gone sooner. The switch: the shard deadline as a function of the fleet median |
+| 2031 | GDDR7-Next; 64 GB flagship; rental at 0.002 to 0.004 per MH/s-hour; hash 3 to 6x today's at the same price. The chip bar is USD 1.4 B at N5. Home miners on retail power are marginal unless the heat mode and the price prompt keep the UK and EU tiers on in winter. Alive; the home share is 10 to 20 percent (approximate). The parameter: the weight-aged reward rule (lane 7 3.1) | A consumer HBM4-class halo card appears (unannounced today): 2 to 4x the read rate of a 2026 card; the home 2026 cards fall to 0.25 to 0.5x of a new card, the GPU cadence twice over. The chip's stack-level edge is the same as the card's, so the per-joule gap closes to about 1.5x. Alive; the installed base shifts to the new card. The parameter: the N bind-point re-measurement per generation | Prover ASICs at 100x; the EF's L1 zkEVM runs on them; SP1-class software moves to ASIC backends. Igneum: proving in consensus verified, home cards prove shards inside the deadline because the deadline is the fleet's; the pool's 20 percent stays with weight. Alive. The risk: if a soundness bug in the ASIC's backend lands, the stop switch of 5.3 is the defence |
+| 2036 | 96 GB cards; rent at 0.0003 to 0.0013; hash 10 to 35x; the emission at the 1 percent tail (86 M IGN a year). Security is 1 percent of market cap a year (tail-emission.md). Igneum lives if the cap is over about USD 50 M (a 24-hour attack at 0.032 percent of cap is USD 16,000 against a rental market that can supply it); dies below that only in the sense every PoW chain does: cheap to attack, nothing to steal. The parameter: the tail | HBM everywhere above the laptop; the f = 1 chip and the halo card are the same memory; the ASIC question is closed by parity and the ladder's N is the remaining difference. Alive. The parameter: N at the verifier's 10 ms ceiling | Every proof is an ASIC proof; the pool pays miners for shards an ASIC proves 100x cheaper; miners buy ASIC prover boards the way they buy cards (USD 500 to 2,000 boards, approximate guess). Igneum: proving is a second card, not a second income. Alive. The parameter: the shard deadline rule |
+
+Where Igneum dies, honestly:
+
+| Death | Scenario | What would be needed to survive it |
+|---|---|---|
+| The stored-dataset chip at N5 is built at a USD 100 M cap in year 1 and holds over a third of hash by year 2 | A, 2028, if the N ladder is not at genesis or the signal never steps it | the N ladder at genesis with its first rung live; the weight-aged reward; the honest sentence that the chip's bar is USD 100 M, so the cap passes it fast or not at all |
+| Idle datacentre hash sets the rent and the home tier leaves; weight concentrates in three hosting firms; a hosting failure is a 30-day finality pause | A, 2031 | the LEAVE item (shipped), the reward rule that pays aged keys, the heat mode and price prompt that keep winter home miners on, and a public "weight by hosting provider" chart so the concentration is seen |
+| A CRQC in 2033 to 2036 (28 to 49 percent inside ten years, GRI) before the key succession has flipped | any, 2033+ | the genesis key succession and the aggregated-vote format shipped by 2030, the flip signalled the year NIST deprecates (2030), not the year a machine appears |
+| A soundness bug in the one proof system while the pool pays on the proof alone | C, any year | two zkVMs on the active list and the 1/3-weight stop switch |
+| The cap never passes USD 20 M: the tail's 1 percent is USD 200,000 a year of security, a day's rental | all, any year | nothing in the protocol; it is the market's verdict, and the design should say so rather than promise a floor |
+
+## 10. Verdict table
+
+| Axis | Finding | Source | Per-tier consequence | Recommendation |
+|---|---|---|---|---|
+| Memory roadmap | tRC flat for about 20 years; HBM4 doubles channels a stack (2026); HBM4E adds pins and a custom base die (2027 to 2028); no consumer HBM, no GDDR8 before 2029 to 2031 | JEDEC, SK hynix roadmap, Lee et al. | a 2026 card keeps its read rate against a 2028 card; 8 and 12 GB leave the installed base by 2030, not the hash | nothing at genesis; re-measure the N rungs per generation (text, a measurement duty) |
+| The cache | consumer LLC 96 to 128 MB; datacentre 256 MB today | chip-model-v3, MI300X (approximate) | an LLC at the cache size gives that card's owners a 2 to 3x shortcut | a cache-size rung on the signal ladder (genesis parameter) |
+| The dataset | 2 GiB to 16 GiB over 28 years is under every card and never binds before year 12 | algorithm.md 5.6 | the prover footprint binds first | nothing; fix the public card-lifetime sentence (text) |

+| Used-GPU flood | 15 to 20 M datacentre GPUs installed by end-2026; residual 25 to 35 percent at 60 months; an H100 mines at 0.65x to 3x a 5090, unmeasured | TechInsights, Omdia, mercatus | 1 percent of a retired fleet is 2 to 35x the equilibrium hash | measure an H100 and an A100 this month (measurement); the reward rule (parameter, lane 7 3.1) |
+| Rental curve | 0.0117 to 0.0003 to 0.0013 per MH/s-hour by 2036 | model on cloudzero's H100 history | attack dollars unchanged at equilibrium; home share falls 10 to 35x | re-price 51-percent.md from a measured rental yearly (text); the cost-vs-rent line on the earnings page (software) |
+| Energy | UK 26.3 p, EU 29 c average, US 17.7 c; heat credit is a third off in the heating season; ERCOT pays industrial curtailment, not homes | Ofgem, Eurostat, EIA, ABC13 | retail-power tiers (UK, DE) are 5 to 9x the industrial price even with heat credited | heat mode, curtailment input, per-region price prompt (software); 2025/422 indicators published (text) |
+| Mining rules | Norway (new sites), Sweden (tax), Russia (regions and Moscow), China (illegal), Kazakhstan and Paraguay (licensed, tariffed); US SEC: mining is not a securities offer | the table in 4.4 | a home miner's risk is regional | the region prompt and banned list in Ember (software) |
+| Proving cost | USD 1.69 to about 0.005 a block in 20 months; four teams at sub-10 s; EF's 2026 metric is kWh a proof; no prover ASIC has shipped a block benchmark | ethproofs, EF, Cysic | a 12 GB card proves alone under 10 s at every rate; beside its miner only at 3x a year | the shard deadline as a function of the measured fleet median (parameter); two zkVMs and the 1/3 stop switch (switch) |
+| Proof-system risk | three soundness-class events in 18 months across SP1 and RISC Zero | LambdaClass, HackenProof, EF | none for miners today; a chain failure only if a proof ever replaces execution for full nodes | never let it (text in spec 10.1); the active-list and stop switch (switch) |
+| Light clients | 25 KB per two days (Ethereum), 22 KB (Mina), a 1 MB STARK in under 100 ms on a phone (StarkWare); a verifying Igneum wallet costs under 0.2 percent of a day's battery | a16z, Mina, cryptotimes, model | nothing a miner notices; every miner serves proofs | serve the segment proof from every node by default (software); the Plonk wrapper for phones, the STARK for nodes (parameter) |
+| Post-quantum | ML-DSA-44 2,420 B signatures; 57 GB a day of naive votes at 8,192 voters, 223 MB with 250x aggregation; CRQC 28 to 49 percent within ten years; NIST deprecates 2030 | FIPS 204, Cloudflare, GRI, NIST IR 8547, model | a miner signs one succession item at migration; nothing hardware-specific | the sig_scheme byte, the key succession, the PQ precompile, the VDF fallback at genesis (parameters); the aggregated-vote format by 2030 (switch) |

+| Scenarios | alive in every 2028 and 2031 cell with one parameter each; dies on an unstepped N ladder, on concentration after the home tier leaves, on a late PQ flip, on a single proof system, or on a cap under about USD 20 M | section 9 | the home tiers are the ones each death removes first | the five "needed to survive" rows of section 9 |
+
+## 11. Three headline findings for the coordinator
+
+1. A stored-dataset chip with the class v4 shadow core pays for itself at about USD 100 M of market cap in Igneum's first two years and about USD 700 M in years 5 to 6 (30 percent share, USD 30 M project, model), and it never needs a node below 28 nm plus N5, so the N ladder at genesis is the only lever and C-HBM4E (2027 to 2028) moves the chip's controller under the memory and cuts its dollar cost further.
+2. Ten years of rental deflation (USD 0.0117 to 0.0003 to 0.0013 per MH/s-hour by 2036) leaves every 51-percent dollar figure unchanged at the equilibrium and cuts the home card's share of the subsidy 10 to 35x; the day an idle datacentre card on 5 c power sets the rent, a UK home miner at 26.3 p loses 7x on electricity, and the heat mode buys back a third, not the gap.
+3. A post-quantum vote at 8,192 voters costs 57 GB a day in naive ML-DSA-44 (19.4 MB a checkpoint) and about 223 MB a day with 250x SNARK aggregation, against a 28 to 49 percent chance of a cryptographically relevant quantum computer inside ten years (GRI 2025) and NIST deprecation after 2030, so the key-succession item, the scheme byte and the aggregated-vote format belong at genesis and the flip belongs in 2030.

+# The last mission, lane 4: what can be invented, judged hard
+
+7 October 2026, morning UK. Lane 4 of the final research programme ("the last mission"), worktree `igneum-wt-mission`. The question: given everything Igneum already has (the horizon one page, the frontier lane's sixteen ideas, the new-PoW lane's three schemes, class v5, finality in the proof, work-stake, the tail, vote-or-burn, the ladder, the pool design, the light client, the phone app), what is the NEXT genuinely new thing a GPU chain could do that none has. Every candidate here was checked against prior art by name and year, run through its own game theory with a model this lane ran (`invent_model.py`, section 0), reviewed in the Monero or Kaspa developer's voice, priced in agent hours with a first gate, and given its per-tier consequence and four persona verdicts. Nothing here touches the devnet. No em dashes. Figures from memory say approximate; figures from a source name it.
+
+the project lead's rulings are applied as a filter before any idea is scored: miners are the security always; no stake and no coin bond; no holder penalised; no device bounty; no fixed-height activations; no calendar dates; no reliance on another chain; no dev fund; no privacy; nothing that becomes a token sale; the lottery and the proving stay separate; emission carries security with no end date. An idea that needs one of these is marked dead in one line.
+
+## 0. Progress, method and the four voices
+
+| Time (UK) | State |
+|---|---|
+| 08:05 | Lane started; read CLAUDE.md, the horizon one page (sections 1 to 3), frontier.md (sections 0 and 3, all sixteen), new-pow.md (3, 4, 6, 7), class-v5-stored-state.md, finality-in-proof.md, work-stake.md, tail-emission.md (one page), vote-or-burn.md, latency-ladder.md, 51-percent.md, pool.md, spec 09, spec 10, phone-app.md, the four persona files, bench-log (rental cost, warp verify, aggregation, 5090 rows) |
+| 08:35 | Prior art checked by WebFetch on primary pages (the session's WebSearch budget was already spent; every page that answered is in the sources list; four pages 404'd and those items are labelled approximate) |
+| 08:51 | `invent_model.py` written and run in the lane's scratch (`mission-invent/out.md`); every table below marked "model" is printed by it |
+| 08:59 | This file written (528 lines, 0 em dashes, not staged); final message to the coordinator |
+
+**Method.** Three passes per candidate. (1) Prior art: the paper, project or repository that did it, with the year, and the one sentence of what differs. (2) Game theory: who gains from cheating, the attack, its cost, the bound; a short numeric model actually run. (3) The hostile review in the Monero or Kaspa developer's voice, then the prototype cost in agent hours, the first measurable gate, the per-tier consequence (home miner 8 / 12 / 16 / 24 to 32 GB, rig, pool user; Windows, Linux, macOS; NVIDIA, AMD, Apple) and four persona verdicts: do now, prototype, watch, never.
+
+**The four voices.** The cryptographer, the consensus engineer and the miner (the miner-community lead) are the persona files in `.claude/agents/`. The fourth, the economist, is defined here from the economy lane's method (`docs/analysis/horizon/economy-and-utility.md`, `tail-emission.md`): every number is priced in rented hash at the measured USD 0.0117 per MH/s-hour (bench-log, "Rental cost of hash", 6 October 2026); an IGN price is an input never a prediction, shown at USD 0.005, 0.02 and 0.10; fees are never assumed to be the security budget; a mechanism that moves income is judged by who pays, who is paid, and whether the payer would rather leave; the per-tier consequence is stated before anyone asks.
+
+**Price basis used throughout.** Subsidy 100 IGN a block at one block a second (the tail-emission recommendation; today's code pays 31.688). Rented hash USD 11.7 per GH/s-hour. CPU verify of one 32-lane unit: 0.441 ms class v3 steady (bench-log line 170), 5.06 ms class v4 cold on the box's core (horizon L2), 1.35 ms per pool share check in isolation (pool.md section 5); the gate is 10 ms. Header 400 B working figure (spec 10.9). Snapshot 114.8 MB (horizon rank 22). Groth16 proof 260 B (SP1 docs), public values with the finality extension 494 B (finality-in-proof section 1).
+
+**What the measurement budget did not allow.** Nothing in this lane needed the box or a GPU pod to reach a verdict; where a first gate needs one, the gate names the command and the expected number and the final message lists it for the coordinator.
+
+---
+
+## 1. Hashing useful to the chain itself, without reopening the useful-work trap
+
+The trap, restated from new-pow section 3.1 and frontier 3.10: a lottery needs a sampleable puzzle with a cheap verifier; any coupling of the puzzle to a scarce skill hands the lottery to the best at that skill (Aleo). The four variants below avoid the trap by keeping the hash kernel byte for byte as shipped and changing only what a miner must HOLD or must have DONE to build the dataset or to be paid. That is class v5's shape (new-pow scheme C: hash rate 63.083 against 63.088 MH/s on the 4090, build +1.4 ms, verifier +0.11 to 0.21 ms per unit), so the question for each is only: what does it add to class v5 that is measurable, and does the addition survive its own game.
+
+### 1.1 What class v5 already delivers, so nothing below re-invents it
+
+| Property | Delivered by class v5 | Where |
+|---|---|---|
+| Every mining operation holds the day's execution state | yes, by construction: `leaf(t) = D[t mod n]` keys every item; a stateless hasher is wrong on every item (the known-failed case) | class-v5 section 3, 4 |
+| Every block names 128 random state leaves per lane any full node can open against `R_d` | yes; the opening RPC is new-pow rank 6 (4 hours, not built) | new-pow 3.3, 7 |
+| The miner must know the chain to within the epoch lead | yes, already since class v3: the program is the 10-minute VDF of a certified checkpoint 20 minutes before the epoch (spec 04 4.3); a miner without the last hour of chain has the wrong program and every hash is wrong | spec 04 |
+| The f = 0 recompute chip must hold the state | yes | new-pow 6 |
+| The pool caveat | stated: a pool ships `D` once a day (6 KB today, 1 to 2 GiB on a used chain) | class-v5 section 3 |
+
+### 1.2 (a) Proof of following: the day's leaves include the last N blocks
+
+**The idea.** Widen class v5 so that the dataset derives from the state AND from the chain's recent blocks: the day's leaf array gains the hashes or receipts of the last N chain blocks before the cut, so a miner proves it relayed or held recent blocks, not only the state.
+
+**Prior art.** Verthash (Vertcoin, January 2021, approximate: the vertcoin.org page 404'd this morning): a 1.2 GB dataset built from the chain's own block headers, random reads per hash. Ethash (2015): dataset from the epoch seed. Class v5 (this project, 7 October 2026): dataset from the execution state. Permacoin (Miller, Juels, Shi, Parno, Katz, IEEE S&P 2014): proof of retrievability of a dealer's file. The combination "state plus recent headers" is new in form; Verthash is the nearest in substance.
+
+**Mechanism.**
+
+| Item | Rule |
+|---|---|
+| Extra leaves | after the state records, one record per chain block in `(daa(C_d) - N, daa(C_d)]`: `0x04 ‖ block_hash ‖ state_root ‖ receipts_root` |
+| Keyed by | `R_d` as every other leaf; the day's cut `C_d` is one hour before the day (class-v5 section 2) |
+| What it forces | a builder must hold the last N headers and receipt roots before the cut |
+| What class v5 forces already | the whole state after `C_d`, which commits to every one of those blocks through `R_d` |
+
+**Game theory.** Nobody gains from cheating because there is nothing to cheat: the state root already commits to the chain. The only question is what a miner must HOLD. Under class v5 a miner holds `D` (the state sample); under 1.2 it also holds N header records it can fetch from any peer in one round trip. Model (section A of `invent_model.py`, the outsourcing row): a key with nothing answers a fetch in about 108 ms over a 100 ms link. The addition forces no holding that a pool's daily delivery does not already satisfy, and the "following" it proves is the following the epoch seed proves every hour at zero cost.
+
+**What is measurable.** Nothing new per block. The receipts are a function of the state transition every executing node already computed; the day's cut already requires the chain to within an hour; the epoch seed requires it to within 80 minutes. The one measurable thing would be a per-block dataset change, and a per-block build is 32 ms on a 4090 (class-v5 section 2) against a 1,000 ms block: a 3.2 percent hash loss on every card every second for a property the program swap gives every hour for free.
+
+**Hostile review (Kaspa voice).** "You have a dataset keyed by a state root that is itself a function of every block in the chain's past. Adding the last N block hashes as leaves adds information the root already carries. If you want 'following', the program swap is your following: a miner that is an hour behind has the wrong kernel. Do not add bytes to a build that already proves the thing."
+
+**Cost and gate.** 0 hours: not built. If someone insists: the gate is the fast-time harness showing a stateful miner with stale headers is refused, which the state root already does.
+
+**Per tier.** No change for any card, rig or pool user; the verifier's RAM unchanged.
+
+**Verdicts.** Cryptographer: never (the root commits to the chain; redundant). Consensus engineer: never (bytes for nothing). The miner: never (nothing to see). Economist: never (no income moves). Verdict: never, with the sentence "proof of following is the epoch seed plus class v5" written into class-v5's litepaper paragraph.
+
+### 1.3 (b) Proof of serving: a reward component for serving headers, snapshots and proofs
+
+**The idea.** A slice of the producer's 80 points is paid only to keys that served data to peers in the window, verified by challenge-response sampled into blocks.
+
+**Prior art.** Filecoin WindowPoSt (2020; spec.filecoin.io: 48 deadlines of 30 minutes a day, randomness from a beacon 20 epochs before the deadline, fee debt on a missed proof); Arweave SPoRA (version 2.4, February 2021, approximate: the docs page 404'd; mining reward requires random access to stored chunks); Sia storage proofs (2015, approximate) and Storj audits (2018, approximate); Celestia data availability sampling (2023, approximate); EigenDA (2024, approximate); Ethereum PeerDAS (EIP-7594, 2024: custody by node id, cell KZG proofs, and the EIP states no reward or penalty for serving); Kaspa archival nodes (a flag on kaspad, unrewarded; the README fetched this morning does not document it, approximate). What differs here: the data served is the chain's own state, the challenger is the next block producer and the randomness is the chain's, and the reward is a slice of the block subsidy to a miner key, not a storage market.
+
+**Mechanism.**
+
+| Item | Rule |
+|---|---|
+| Challenge | block B's producer draws `c` keys from the weight table at the last certified checkpoint in B's past, by weight, seeded by B's prehash; for each, 8 leaf indices of the day's `D` |
+| Answer | the challenged key signs `(B, leaves, openings against R_d)` and any producer carries it within `T` blocks |
+| Failure | no answer carried in `T` blocks after B |
+| Reward | x of the 80 producer points conditional: a key with an unanswered challenge in the window is paid 80 - x on its next blocks until it answers one |
+| Bytes | 8 leaves x (64 + 25 x 32) + 96 B signature = 6.8 KB per answer; 1 challenge per block = 0.61 GB a day on every node (model, table A2) |
+
+**Game theory (model, section A).**
+
+| Attack | Cost | Bound |
+|---|---|---|
+| Serve yourself from your own nodes | zero; the challenged key answers its own challenge from the state it already holds to mine under class v5 | the proof reduces to "I hold what class v5 already makes me hold" |
+| Outsource the answer to a peer that holds the state | one fetch, about 108 ms on a 100 ms link; any deadline over one block (1,000 ms) admits it | the proof becomes "someone with the state answered"; Filecoin's answer is sealing (replicas slower to fetch than to read), which costs hours of CPU per sector and does not fit a daily dataset |
+| Producer griefing: refuse to carry answers | an answer gossips to every producer; withholding for T blocks needs a majority of producers for T seconds | the same bound finality lives with |
+| Sybil the draw | the draw is by weight; a dust key is never drawn; splitting a key splits its draws and its loss | nothing to gain |
+| Loss to a key that never serves at x = 8 | 0.1 percent key: 691 IGN a day (USD 3.5 at 0.005); 10 percent key: 69,120 IGN a day | the price of not running a node, which a miner under class v5 must run anyway |
+
+**Load per key.** At 10,000 keys and one challenge per block a key's share of challenges is its weight share: 8.64 a day for a mean key, 0.06 MB of upload a day, 0.006 kbit/s. At 128 leaves per challenge and 8 per block, 7.6 MB a day. Every home connection carries it (table A1). The cost is on the chain, not the key: 0.61 to 76.5 GB a day of answers on every node depending on the two parameters.
+
+**Hostile review (Monero voice).** "You pay a miner for proving it holds the thing your own lottery forces it to hold. The challenge adds 0.6 GB a day to every node to learn nothing, and the fetch bound makes it 'someone served', which is what gossip already guarantees. Filecoin pays for storage because storage is the product; your product is blocks. The one honest version is unpaid: a light-client spot check of availability, which is your rank 6 RPC."
+
+**Cost and gate.** 0 hours as a reward; 4 hours as new-pow rank 6 (the opening RPC, unpaid), whose gate is 128 openings verifying against `R_d` on the fast-time network.
+
+**Per tier.** As a reward: every tier pays bytes (0.61 GB a day of chain) to prove what class v5 proves. As the unpaid RPC: a node serves 102 KB per request on demand; a light client gains a daily availability spot check; no card changes.
+
+**Verdicts.** Cryptographer: never as a reward, do the RPC (the outsourcing bound makes the proof vacuous). Consensus engineer: never (0.61 to 76 GB a day for no new property). The miner: never (a line item nobody understands). Economist: never (it moves x points for a service already compelled). Verdict: never as protocol; new-pow rank 6 stands.
+
+### 1.4 (c) Proof of propagation: signed receipts from peers in the next block
+
+**The idea.** A block carries receipts, signed by peers' vote keys, that they received the previous block within t seconds; the producer is paid a slice for fast propagation.
+
+**Prior art.** Bitcoin's Relay Network and FIBRE (Matt Corallo, 2016; bitcoinfibre.org: UDP, forward error correction, compact blocks; no protocol payment to relays). Kaspa's relay is the ordinary p2p flow with no receipts (approximate). "Proof of relay" papers: this lane found none that shipped; the arXiv search for "proof of latency" returned five unrelated papers (section 7.11). GHOSTDAG itself: a slow block is red and its subsidy goes to its merger (spec 02 2.5), which is the propagation reward the DAG already pays.
+
+**Mechanism and why it dies.**
+
+| Item | Problem |
+|---|---|
+| The time field | no consensus clock finer than Kaspa's timestamp window (a header at most 10 s ahead of the clock, spec 02; the DAG tolerance 132 s in frontier 3.1); a receipt's "within t seconds" is the signer's word |
+| Sybil receipts | peers are keys; weight-drawn receipts cost the attacker nothing because its own keys sign its own receipts |
+| Bytes | 8 receipts x 136 B = 1,088 B per block, 94 MB a day; 32 receipts 376 MB a day (model, section H) |
+| What the DAG already does | at 1 block/s on Devnet 2 run B the red rate was under 2 percent from minute six (bench-log, "Block rate on Devnet 2"); a block that propagates slowly is red and its subsidy moves to its merger: the propagation reward exists and is measured in blue blocks, which are also the vote weight |
+
+**Hostile review (Kaspa voice).** "GHOSTDAG is a proof of propagation. Blue means it arrived in time; red means it did not; the k parameter is the clock. Receipts signed by the people who benefit from them prove nothing and cost 94 MB a day."
+
+**Verdicts.** All four: never. Cost 0.
+
+### 1.5 (d) Proof of state availability with block-derived challenges and the producer's own next block
+
+**The idea.** As 1.3 but the challenge is issued by the producer's own next block (so no trusted party), answered on demand, and the reward slice is paid only to keys that answered.
+
+This is 1.3 with the challenger named. The trap the brief names ("who issues challenges without a trusted party") is answered correctly by block-derived randomness and the producer's next block, and the answer does not rescue the idea: the outsourcing bound (a fetch in 108 ms) and the self-serving bound (the key answers from the state class v5 makes it hold) are unchanged. The one new element, "the producer's own next block" as the carrier, makes the producer the judge of its own challenge and needs a second producer to carry the answer for fairness, which is 1.3's `T` blocks.
+
+**Verdicts.** All four: never as a reward; the unpaid availability spot check (new-pow rank 6) is the whole of what survives. Cost 4 hours for the RPC.
+
+### 1.6 Section 1 in one table
+
+| Variant | Prior art | New? | Survives its game? | Cost | Verdict |
+|---|---|---|---|---|---|
+| (a) proof of following | Verthash 2021; class v5 2026 | in form only | yes, because it does nothing | 0 | never: the epoch seed and the state root already prove following |
+| (b) proof of serving | Filecoin PoSt 2020; Arweave SPoRA 2021; PeerDAS 2024 (unrewarded) | the reward to a miner key is new | no: outsourced in 108 ms; self-answered under class v5 | 0 (4 for the unpaid RPC) | never as a reward |
+| (c) proof of propagation | FIBRE 2016 (unpaid); GHOSTDAG's reds | no | no: time is unverifiable; receipts are Sybil-free | 0 | never |
+| (d) state availability by the producer's next block | same as (b) | the challenger rule is new | no, same bounds as (b) | 4 (RPC) | never as a reward |
+
+---
+
+## 2. A block reward that pays for availability of the chain's state
+
+**The exact split proposal, as asked.** Of the 80 producer points, x are conditional on the key having served state in the window, verified as in 1.5; the rest unconditional. The candidate x: 2, 4 or 8 (8 would mirror the signing bonus of vote-or-burn, which pays 8 of the 80 for signing).
+
+**The attack: serve yourself.** The challenged key answers from the state it holds; the challenge is drawn by weight, so the key's own weight is the only thing that decides how often it is asked. A key that runs a node (every class v5 miner) passes every challenge at zero marginal cost. A key that runs no node and proxies to a pool passes every challenge at one fetch. Nobody fails except a key whose node is down, which is the signing bonus's case already (vote-or-burn section 1: the honest-silence classes), so the conditional slice is a second liveness bonus on the same event.
+
+**The Sybil bound.** Vote-key weight as the challenge draw: a dust key is never drawn, a split key is drawn in proportion, so splitting gains nothing. Correct, and it also means the mechanism measures the keys that already mine, who already hold the state.
+
+**Per-tier cost (model, table A1).** At 10,000 keys, one challenge per block, 8 leaves: a mean key uploads 0.06 MB a day; at 8 per block and 128 leaves, 7.6 MB a day, 0.7 kbit/s. Any home connection on any OS carries it. The chain pays 0.61 to 76.5 GB a day of answer bytes on every node for the two parameter corners.
+
+**What it costs a key that never serves (model, table A3).** At x = 8: 0.01 percent key 69 IGN a day, 0.1 percent 691, 1 percent 6,912, 10 percent 69,120 (USD 0.3 to 346 at 0.005). The same shape as the signing bonus and for the same population.
+
+**Hostile review (Monero voice).** "Two liveness bonuses on one event is one bonus with worse accounting. Your signing bonus already pays 8 points for 'my node is up and following'; this pays x more for 'my node is up and holds the state', which under class v5 is the same node. Merge them or drop this."
+
+**The economist.** No payer wants it: the slice comes from the same producer share, so it is a transfer from keys whose nodes are down to keys whose nodes are up, which the signing bonus already does; the chain pays gigabytes a day for the second accounting.
+
+**Verdicts.** Cryptographer: never (vacuous under the outsourcing bound). Consensus engineer: never (bytes). The miner: never (a second deduction line is read as a second fine; vote-or-burn's 93 to 97 percent respect for one bonus at genesis would not survive two). Economist: never. Cost 0.
+

+
+## 3. Mining that is also a light-client service
+
+**The idea.** Every miner's node serves finality-in-proof public values (494 B) and certificate bitmaps to phones; a reward slice or a fee market pays for it.
+
+**Prior art.** Ethereum Portal Network (2021 to 2026; ethportal.net: history, state and beacon networks; clients Trin, Nimbus Portal (Fluffy), Ultralight, Shisui; the site states no reward for nodes). Helios (a16z, 2022, approximate for the year; github: weak-subjectivity checkpoints as the root of trust, sync-committee verification). Mina's snarkers (2021, approximate): a fee market for SNARK work inside the protocol. Celestia light nodes and bridges (2023, approximate). What Igneum has that none of these had: the serving node is a miner with a funded key, and the object served (494 B of public values plus a 260 B Groth16 proof, once the wrapper lands) is tiny and self-certifying.
+
+**Whether it is a protocol item.** No. The object is public values a node already holds; serving it is one HTTP or wss endpoint (spec 10.7's read-only table); the phone app already reads nodes it pins (phone-app section 5). A fee market for 786 bytes is a transaction per fetch at 0.0051 IGN (frontier 3.13's transfer floor), which no phone will pay per refresh and no node needs. A reward slice is 1.3's reward with a different payload and the same vacuity.
+
+**What it is: an Ember feature.** Ember in verify mode is frontier 3.8 (do now, 20 hours). The light-client serving side is a line in the node's RPC: `igneum_getLatestWrappedProof`, served to any client, rate-limited per IP, with the phone app pinning the user's own node by its card (phone-app section 5) or the seed list. Bytes per day per phone: 786 B per refresh, 2,880 refreshes a day if it polls every checkpoint = 2.3 MB (spec 10.5's phase-two figure, 2.30 MB, matches).
+
+**Game theory.** A node that lies serves a proof that does not verify, which the phone refuses; a node that withholds is replaced by the next pinned node. No payment, so no cheating for pay. The one attack is topology: a phone pinned to one node is eclipsed by that node, which spec 10.6's N of M seed agreement bounds.
+
+**Hostile review (Kaspa voice).** "Serving 786 bytes is not a service you price. It is a feature of a node. Put it in the app."
+
+**Cost and gate.** 4 hours (the RPC and the rate limit) on top of frontier 3.8's 20; gate: a phone on cellular shows "locked, voter set verified in the proof" from a miner's Ember node with no other node asked, bytes counted on the Verify screen.
+
+**Per tier.** Every miner's Ember serves phones by default behind a per-IP limit (a home upload of 786 B per request is nothing); a holder's phone gets its proof from any miner; a pool user's member process is the same Ember; no card or OS difference.
+
+**Verdicts.** Cryptographer: do now (as the Ember line). Consensus engineer: do now, not a protocol item. The miner: do now ("my node serves my phone" is a sentence miners like). Economist: do now, unpaid; a fee market here would price a service below its transaction cost.

+
+## 4. A decentralised pool in the protocol
+
+### 4.1 The design, as asked
+
+| Item | Rule |
+|---|---|
+| A share | a block header at a low difficulty, signed by the miner's own payout key, referencing the round `r` |
+| The round | the window of blocks between two chain-block boundaries, e.g. 600 chain blocks (the record window of spec 7.8) |
+| Carriage | any block carries shares it has seen; a share is valid if its header's PoW passes the share target and its parents are in the carrier's past |
+| Payout | a coinbase rule every node computes: the producer share of blocks in round r is split by share weight (`2^-s`) over the shares carried in round r's blocks, PPLNS style, minus nothing (no operator, no fee) |
+| Variance reduction | a miner is paid by its shares whether or not it found a block |
+
+### 4.2 Prior art
+
+| Name | Year | What it did | What differs |
+|---|---|---|---|
+| P2Pool (Bitcoin) | 2011 (Forrest Voight, approximate) | a sidechain of shares at a 10-s target; payouts in the coinbase of found blocks; no operator | the shares were off the main chain; nodes did not verify them |
+| FruitChains | Pass and Shi, 2016 (eprint 2016/916) | "fruits" as low-difficulty PoW objects carried in blocks, rewarded fairly: any honest set with phi of the hash gets at least (1 - delta) phi of the reward | the exact in-protocol shape asked for here, published nine years ago; never shipped on a major chain |
+| SmartPool | Luu, Velner, Teutsch, Saxena, 2017 (eprint 2017/019) | shares committed by Merkle root to an Ethereum contract, verified by sampling; miners paid 0.6 percent of block rewards in transaction fees | a contract, not a coinbase rule; the operator is the contract |
+| Monero P2Pool | SChernykh, 2021 (github SChernykh/p2pool) | a 10-s share sidechain merge-mined with Monero, PPLNS over 2,160 shares (6 hours), no operator, payouts as coinbase outputs | off the main chain; Monero nodes do not verify shares |
+| Stratum V2 job negotiation | Braiins, 2019 onward (approximate) | the miner builds its own template; the pool must pay shares on it | an operator remains; the vote and template are the miner's (spec 09 already takes this) |
+| Ocean (Bitcoin) | 2023 (approximate) | an operator pool with on-chain payouts per block (TIDES) | an operator remains |
+| Braidpool | 2021 onward (github braidpool/braidpool: in development, not production) | a DAG ("braid") of shares; miners build their own blocks; constant-size payouts | not shipped |
+| Kaspa "SPECTRE shares" | none found | | Kaspa pools are Stratum bridges with operators (approximate) |
+
+So the in-protocol pool is FruitChains (2016) with Igneum's payout key and round. It is not new.
+
+### 4.3 The bytes and the verifier (model, section B)
+
+| Miners | Share interval | Shares per block | Bytes per block (compact 169 B) | Per day on every node | Verifier cores at 1.35 / 5.06 / 10 ms per share |
+|---|---|---|---|---|---|
+| 1,000 | 10 s | 100 | 16.5 KB | 1.5 GB | 0.14 / 0.51 / 1.0 |
+| 10,000 | 10 s | 1,000 | 165 KB | 14.6 GB | 1.35 / 5.06 / 10.0 |
+| 100,000 | 10 s | 10,000 | 1,650 KB | 146 GB | 13.5 / 50.6 / 100 |
+| 100,000 | 100 s | 1,000 | 165 KB | 14.6 GB | 1.35 / 5.06 / 10.0 |
+| 100,000 | 1,000 s | 100 | 16.5 KB | 1.5 GB | 0.14 / 0.51 / 1.0 |
+
+The full-header form (496 B) is 2.9x the bytes. The verifier at the class v4 cold figure (5.06 ms) needs 50 cores per node at 100,000 miners and a 10-s share interval, which no home node has; at a 1,000-s interval it fits one core and 1.5 GB a day, but then the variance reduction is the thing being bought and it has gone:
+
+| Income source | Paying events per day | CV of a day's income | CV of a month |
+|---|---|---|---|
+| solo 17 MH/s at 1 TH/s | 1.5 | 82.5 percent | 15.1 percent |
+| shares at 1 per 1,000 s | 86 | 10.8 percent | 2.0 percent |
+| shares at 1 per 100 s | 864 | 3.4 percent | 0.6 percent |
+| shares at 1 per 10 s | 8,640 | 1.1 percent | 0.2 percent |
+
+At 100,000 miners the chain can afford one share per 1,000 s per miner (1.5 GB a day, one core), which gives a small card a 10.8 percent daily CV: a real improvement on 82.5 percent, at the cost of 1.5 GB a day on every node including every phone-class light client that would want to verify the coinbase. At 10,000 miners and 100 s the same bytes buy 3.4 percent.
+
+### 4.4 Does the vote key and sortition machinery give a round for free?
+
+Yes for the ROUND, no for the SHARES. W2 already counts blue blocks per key over 30 days, and the shard sortition already draws by that count (spec 7.2). A "round" and a per-key tally exist in every node. What does not exist is a sub-block unit of work, and that is the whole cost: every share is a PoW object every node verifies. The free version is to pay by BLOCKS over a window, which the protocol already does (every block pays its producer), so the free "pool" is the chain itself, and its variance is the solo row above.
+
+### 4.5 The attacks
+
+| Attack | Effect | Bound |
+|---|---|---|
+| Share withholding (find a block, publish only shares) | in an operator pool the withholder is paid shares and the pool loses the block; here the round's payout IS the blocks found, so a withheld block shrinks everyone's payout including the withholder's own share of it: the withholder loses `(1 - its share) x 80` points and gains nothing | self-defeating; FruitChains' fairness bound is the formal version |
+| Share stuffing | every share is PoW at the share target, so a fake share costs its hash; stuffing is mining | none needed |
+| Share grinding on the round boundary | a share's round is fixed by its parents; a share straddling a boundary is a DAG event nodes already order | none needed |
+| A majority refusing to carry others' shares | it earns the majority a larger split of the round; this is red-flooding by another name, 26 to 28 percent of honest income at 51 percent (51-percent.md section 1) | the same bound as today's reds |
+| Verifier DoS | a flood of invalid shares costs a node 5 ms each before rejection | the per-peer rate limits of the p2p layer; the ban score |
+
+### 4.6 The honest verdict against docs/plans/pool.md
+
+The shipped pool v0 (5 October 2026, rebased 6 October) already removes the two things an in-protocol pool is for: the operator holds no key and no vote (members sign their own votes through their own verifiers, spec 9.7), and the share rule is fixed by spec 9.8 so the member keeps its own ledger. The measured operator cost is 1.35 ms per share check (4,800 to 22,700 members per core) and 1 percent fee by default. What the operator still controls: transaction choice for mode A members who do not check (mode C fixes it), and the payout ledger's honesty (the member's own ledger plus the chain's blocks under its key bound it).
+
+The finished form is therefore the pool design plus one addition the brief names: **a verifiable payout contract**, which is SmartPool (2017) on Igneum's EVM: the operator posts the round's share Merkle root and the payout list; any member can prove under-payment with its own share log against the root; the contract pays from the pool address. Cost 16 hours (contract 6, operator posting 4, member proof and the Ember line 6). Gate: a member whose share is dropped from the root proves it on the fast-time network and is paid; an honest round costs the operator one transaction. Bytes on chain: 32 B per round per pool. Verifier cost on nodes: nothing per share.
+
+**Hostile review (Monero voice).** "P2Pool exists because we did not want shares on the main chain; your numbers say why: 14.6 to 146 GB a day. Our P2Pool is a sidechain nobody but miners runs. Build that if you want no operator; it costs your chain nothing." Answer: a Monero-style P2Pool sidechain for Igneum is an app a pool operator could ship (the share chain's only chain-side object is the coinbase payout list), and it is the same code as the pool v0 member minus the server; the lane recommends the contract first because it keeps every existing pool (HiveOS, WhatToMine listings) and makes them verifiable.
+
+**Per tier.** Home miner on any card: nothing changes in the worker; under the contract a member can prove under-payment from its own log. Rig: one key per rig as today. Pool user: the pool's round is public. Node operator: 32 B per round per pool instead of 1.5 to 146 GB a day. Light clients: unchanged.
+
+**Verdicts.** Cryptographer: never in protocol (FruitChains is the prior art and the bytes are the reason it never shipped); prototype the contract. Consensus engineer: never in protocol (50 cores per node at 100,000 miners on a 10-s share); the contract 16 hours. The miner: never in protocol (a chain that grows 14.6 GB a day from shares is the first thing a reviewer attacks); the contract is what listings want. Economist: the operator's 1 percent is already below SmartPool's 0.6 percent plus gas (approximate); the contract makes the 1 percent honest. Verdict: never in protocol; prototype the verifiable payout contract, 16 hours.
+
+---
+
+## 5. Heat as product
+
+**The idea.** Ember's "heat mode" targets a room temperature or a schedule: the card mines when the room wants heat and idles when it does not; the chain does nothing.
+
+**Prior art.** Heatbit (2022 launch, approximate; heatbit.com this morning lists Bitair at 25 W, 1.2 TH/s, USD 179 to 249, and names earlier Maxi and Trio models), 21energy (Austria; Ofen 3 heaters EUR 1,658 to 3,325, "7 to 10 kW" central-heating models coming, 21energy.com), Qarnot (France, founded 2010, approximate, the Wikipedia page 404'd; QRad computing heater 2013, approximate; sells HPC and heats buildings), MintGreen in North Vancouver (2021, approximate), the Finnish and French district-heat trials (approximate; no page fetched). Every one is an ASIC or HPC box sold as a heater. None is a GPU chain's own client with a thermostat. Ember's version is new as a client feature and nothing else.
+
+**Numbers (model, section C).** A 300 W card delivers 300 W of heat at the card's electricity price. The competition is a gas boiler at 90 percent or a heat pump at COP 3.
+
+| Region | Card per hour | Gas boiler, same 300 W | Heat pump COP 3 | Resistive electric | Card must earn per hour to match boiler / heat pump |
+|---|---|---|---|---|---|
+| UK (Ofgem, 1 Oct to 31 Dec 2026: 26.32 p electricity, 7.97 p gas) | 7.90 p | 2.66 p | 2.63 p | 7.90 p | 5.24 p / 5.26 p |
+| EU (Eurostat H2 2025: EUR 0.2896; gas EUR 0.11 approximate) | 8.69 c | 3.67 c | 2.90 c | 8.69 c | 5.02 c / 5.79 c |
+| US (EIA July 2026: 18.31 c; gas 5 c approximate) | 5.49 c | 1.67 c | 1.83 c | 5.49 c | 3.83 c / 3.66 c |
+
+Against a resistive heater (a bedroom panel, a US baseboard) the mining heat is free and every IGN earned is profit. Against a boiler or a heat pump the card must earn about 5.3 p an hour in the UK.
+
+| Network hash | IGN per hour, 100 MH/s card at 100 IGN a block | at USD 0.005 | at 0.02 | at 0.10 |
+|---|---|---|---|---|
+| 100 GH/s | 360 | USD 1.80 | 7.20 | 36.00 |
+| 1 TH/s | 36 | 0.18 | 0.72 | 3.60 |
+| 10 TH/s | 3.6 | 0.018 | 0.072 | 0.36 |
+
+So at 1 TH/s and USD 0.02 a 5090-class card earns 72 US cents (about 55 p) an hour and heats for 7.9 p: a heater that pays. At 10 TH/s and USD 0.005 it earns 1.8 cents and the heat costs 5.3 p more than gas: a heater that costs 3.9 p an hour net, which is still under the resistive panel it replaces in a room without a radiator. The honest sentence for the app: "In heat mode your card is an electric heater that also earns; whether it beats your boiler depends on the network and the price, shown live."
+
+**Game theory.** None on the chain: a heat-mode miner is a miner with a schedule. One effect to name: seasonal hash. If heat mode becomes a large share of hash, winter hash rises and summer hash falls in the northern hemisphere; the DAA absorbs it, and the 30-day weight window means a summer departure of heat miners is a slow slide, not a departure event (the 10 percent per hour rule is not touched by a thermostat that ramps over weeks).
+
+**Hostile review (Monero voice).** "A thermostat in a miner is a feature every miner GUI has had since 2014 (approximate: temperature targets in miner software). Call it heat mode if it sells; it changes nothing about the chain." Correct.
+
+**Cost and gate.** App feature, 6 hours: a target-temperature input, the schedule, a sensor source (the OS's, or the card's own temperature as a proxy with a stated error), the live "earns X, heats Y, your boiler would cost Z" line from the tariff the user enters (phone-app 4.1 already has the tariff field). Gate: a room sensor loop on PC 1 holds a set temperature within 1 degree over four hours while the hash rate follows the duty cycle, logged.
+
+**Per tier.** An 8 GB card at 150 W is a 150 W heater (the small-room case); a 5090 at 326 to 575 W (the ladder page's TGP range) is a large-room heater; a rig is a space heater that should not be in a bedroom; a pool user's duty cycle shows as a share-rate pattern the pool sees; macOS: the M5 Max at low watts is a poor heater; Windows and Linux alike.
+
+**Verdicts.** Cryptographer: do now (no protocol content). Consensus engineer: do now, 6 hours. The miner: do now (the one feature a home miner in a cold flat asks for first; the number line must show when it loses to gas). Economist: do now, with the tariff line mandatory so nobody reads "free heat".
+
+---
+
+## 6. Phone-verifiable everything
+
+**What remains after finality-in-proof and the WASM verifier (horizon rank 19).** Finality-in-proof gives 494 B of public values that say "locked at checkpoint i by x of y weight" under one proof; rank 19 gives the Groth16 or Plonk wrapper verified in a tab. What is left is the last mile: carrying that object with no network, and a "verify this block" link on the explorer.
+
+**Prior art.** Mina (2021, approximate): a constant-size recursive proof of the whole chain, verified on a phone, with proof-of-stake under it. zkSync's block proofs on Ethereum (2023, approximate): verified by a contract, not a phone. Helios (a16z, 2022): a light client in WASM, trust rooted in a weak-subjectivity checkpoint. No proof-of-work chain has a phone-verifiable finality object; after finality-in-proof Igneum does, and the QR is only packaging.
+
+**The object (model, section D).** Groth16 proof 260 B (SP1 docs) + public values 494 B + verifying-key id 32 B = 786 B. A version 40 QR at level L holds 2,953 B; a version 25 at level M about 1,000 B (approximate). So one QR carries the proof with room for a block hash and a receipt path of up to about 2 KB, and a phone with the pinned verifying key verifies it with no network: one bn254 multi-pairing, of the order of 2 to 5 ms native on a phone (approximate; Helios and the xycloo WASM demos are the order-of-magnitude anchors, 10 to 50 ms in WASM, frontier 3.4). The URL form is the same bytes base64 in a fragment, 1,048 characters, under every browser's limit.
+
+**What the phone learns with no network.** That some chain with this chain id, under this aggregator program, had checkpoint i locked by x of y weight, with state root R and history root H, and (with the receipt path) that transaction T is in a block at or below the lock. What it cannot learn offline: that this is the LATEST lock (staleness: the `lock_daa` field lets it show the age against its own clock, labelled "age by your clock").
+
+**The wrapper's cost on a 5090.** SP1's docs give PLONK as about 1 min 30 s longer than a compressed proof and Groth16 as the recommended on-chain form at 260 B; the wrap runs on the CPU in gnark whatever the GPU (approximate, from memory of SP1's wrapper architecture). So the wrap is not per segment (8 s): one wrapper machine wraps one proof per 90 s, and the chain's "latest wrapped proof" is 38 segments behind the tip at a 300-s cadence or 8 behind at 60 s with two wrapper machines (model, table D). The measurement the design needs is the one frontier 3.4 names (R4): wrap the pinned aggregator proof on a 24 GB fleet card and the box's CPU, record seconds and RAM. Expected, approximate: 60 to 180 s and 16 to 32 GB of RAM.
+
+**The explorer link.** "Verify this block" on the explorer renders the QR and the URL for the newest wrapped proof whose history covers the block, plus the block's MMR path; the tab verifies it with rank 19's WASM verifier and shows the milliseconds. 4 hours once rank 19 lands.
+
+**Game theory.** A forged QR fails verification; a stale QR shows its age; a QR from another chain id is refused. A soundness bug in SP1 forges a lock on the phone and not on the chain (full nodes verify the BLS certificate natively, finality-in-proof 5.1), which is the stated light-client row.
+
+**Hostile review (Kaspa voice).** "A QR that says 'locked' with no network says 'locked as of when the QR was made'. Say the age in big letters or you will have people paying against last week's lock." Correct; the age line is in the design.
+
+**Cost and gate.** 8 hours (QR and URL packing 2, the phone verify call on the shared `igneum-light` engine 4, the explorer link 2) plus rank 19's 16. Gate: a phone in airplane mode scans a QR printed from the explorer and shows "locked at checkpoint i, x percent of weight, age 4 minutes by your clock, verified in N ms"; a QR with one byte changed is refused.
+
+**Per tier.** Holders: a proof in their pocket. Miners: their node serves the wrapped proof (section 3). Rollup customers: the same 786 B is what their bridge verifies. Node operators: one wrapper machine per network at a 300-s cadence (a box, not a card).
+
+**Verdicts.** Cryptographer: do now after rank 19 (the first offline-verifiable PoW finality). Consensus engineer: do now (nothing in consensus). The miner: prototype (nice, not what miners ask for). Economist: do now (the cheapest public proof of the phase-two claim; the wrapper machine is one box).

+
+## 7. More candidates, generated and judged
+
+Twelve more. The first four are this lane's own (7.1 to 7.4); the rest are the brief's list, judged.
+
+### 7.1 A weight-backed peer directory in the coinbase (this lane's candidate)
+
+**The idea.** A block producer may opt in to carry its node's reachable address (IPv6 plus port, 18 B) in its coinbase extra data, signed by the vote key the header already names. The chain becomes its own seed list: a fresh client draws its outbound peers from the last 30 days of carried addresses, weighted by the carrying keys' W2 weight. No DNS seed, no shipped seed list beyond genesis peers, no operator.
+
+**Prior art.** Bitcoin's DNS seeds and `addr` gossip (2011 onward, approximate); Ethereum's ENR and discv5 (2019, approximate); Kaspa's dnsseeder (approximate); the eclipse attack paper (Heilman, Kendler, Zohar, Goldberg, USENIX Security 2015) and its address-bucket fixes. No chain this lane knows writes reachable addresses into blocks under the producer's key with weight-weighted draws. New in form; the pieces (addr gossip, weighted sampling) are old.
+
+**Mechanism.**
+
+| Item | Rule |
+|---|---|
+| Object | `IGNA`-style section: `0x05 ‖ ip16 ‖ port2`, opt-in, at most one per block, signed by the header's vote key (the key reveal already proves possession) |
+| Directory | every node keeps the last window's entries keyed by vote key hash (one address per key, newest wins) |
+| Draw | a client picks outbound peers by the key's W2 weight; keys under dust are not drawn |
+| Bytes | 18 B per block = 1.56 MB a day on every node (model, section E); 30 days at most 2.6 M entries, far fewer after de-duplication by key |
+
+**Game theory (model, table E).** An attacker with share a of the 30-day weight lists share a of the directory. With 8 outbound peers drawn by weight, the probability every peer is the attacker's is a^8: 2.6e-6 at 20 percent, 1.8e-4 at 34 percent, 4.6e-3 at 51 percent; with 16 peers 6.6e-12, 3.2e-8, 2.1e-5. Against this, a DNS seed is one operator and a shipped list is one release key. The attack that remains: listing honeypot addresses under honest-looking keys costs the attacker 30 days of mining per key, the same bound as every other weight-backed thing on this chain. Griefing: a producer lists a victim's address to draw traffic to it; bounded by one address per key per block and the signed key, so the lister is named on chain.
+
+**Hostile review (Kaspa voice).** "Your reachable miners are the rigs and the seeds; home miners are behind NAT and will list nothing or list a dead address. The directory is a list of rigs weighted by rigs, which is the thing you said you wanted to avoid (frontier 3.8's Kaspa attack). Also a 30-day-old address is a dead address." Answer: the client draws from the newest entries first with the weight as the tie-break, a liveness probe before use is the ordinary `version` handshake, and the rigs-weighted list is still a list of parties that mined 30 days of public blocks rather than one DNS operator. The NAT point stands and is the measurement.
+
+**Cost and gate.** 10 hours: the coinbase section and signature check (3), the directory and the weighted draw in the node (4), the client's use in Ember verify mode and the phone (3). Gate: a fresh node with no seed list and genesis peers only reaches 8 outbound peers from the directory on the fast-time network; an eclipse harness with a 34 percent attacker listing 34 percent of addresses eclipses the fresh node in under 0.1 percent of 1,000 starts (expected 1.8e-4 at 8 peers).
+
+**Per tier.** Home miner: opt-in, off by default (NAT); a rig and a seed node opt in; a pool node opts in; the phone and Ember verify mode gain a seed list with no DNS; no card, OS or vendor difference; node operators store 1.56 MB a day.
+
+**Verdicts.** Cryptographer: prototype (a weight-backed seed list is the right shape; measure the NAT fraction). Consensus engineer: prototype (10 hours, nothing in fork choice). The miner: watch (home miners will not opt in; rigs will; fine). Economist: prototype (removes one operator from the trust row for 1.56 MB a day).
+
+### 7.2 Sign-in with Igneum: 30 days of public work as a login (this lane's candidate)
+
+**The idea.** A vote key signs a challenge to prove its W2 weight to a third party: a rental marketplace, a forum, a faucet, an airdrop-free allowlist. The verifier reads the weight from any node or the finality-in-proof public values. Sybil cost is 30 days of mining per identity.
+
+**Prior art.** Hashcash (Back, 1997): proof of work as an anti-spam stamp. Sign-In with Ethereum (EIP-4361, 2021): a signed message as a login. Proof-of-humanity and Gitcoin Passport (2021 onward, approximate): social Sybil resistance. No chain has a non-transferable, work-earned weight per key to sign with; Igneum does.
+
+**Game theory.** A key's weight is worth its 30 days of pool income (work-stake section 5: 2,793 IGN for an 8 GB card at 100 GH/s), so lending it to a login is lending a reputation that cannot be split without halving each half. A marketplace that gates on weight gets a Sybil cost it cannot buy elsewhere. The attack: a key used as a login is a key whose secret is on a machine that talks to websites; the pool spec's one-signer rule (9.6 item 3) and the equivocation strip mean a stolen key is burned by its thief in one double vote. The login must therefore be a delegated session key signed once by the vote key, never the vote key online.
+
+**Hostile review (Monero voice).** "You are building an identity out of a mining key. Miners do not want identities; that is why they mine." Answer: opt-in, delegated, and the first customer is the rental escrow of frontier 3.13, which already needs the key.
+
+**Cost and gate.** 6 hours (the delegation message, the verifier library in `igneum-light`, an Ember button). Gate: a web page verifies a delegated signature against a node's weight for one key and refuses a key under dust.
+
+**Per tier.** Any key above dust (100 blocks a window; 3.86 MH/s at 100 GH/s) can sign in; an 8 GB card qualifies at every network size up to about 440 GH/s (where 17 MH/s falls under dust, arithmetic on work-stake section 5); below that, nothing.
+
+**Verdicts.** Cryptographer: watch (the delegation design is the whole risk). Consensus engineer: watch (not consensus). The miner: watch. Economist: prototype only with the rental escrow as the first user.
+
+### 7.3 Public timestamping on the proof chain (this lane's candidate)
+
+**The idea.** Any hash posted in an Igneum transaction is, 60 to 93 s later, inside a certified checkpoint and, after the segment proof, inside a 786 B offline-verifiable object (section 6). OpenTimestamps (Todd, 2016, approximate) does this on Bitcoin with hours of latency and a Merkle aggregator; Igneum does it with the lock latency and a proof a phone verifies.
+
+**Game theory.** None: a transaction with a hash. The base fee burns; the priority fee pays. The product is the receipt path in the QR.
+
+**Cost and gate.** 4 hours (a contract that emits the hash in a log, the receipt path in the explorer link of section 6). Gate: a timestamp verified offline on a phone from a QR.
+
+**Verdicts.** All four: do now once section 6 lands; it is section 6's first use. The economist: a product with a fee a user pays, which is the kind the utility lane wants.
+
+### 7.4 Hash-rate futures as an app (this lane's candidate, judged against ruling)
+
+**The idea.** Braidpool's stated purpose: a miner sells its future shares forward for cash now. On Igneum a miner could sell its next window's pool income (the work-stake bond) forward.
+
+**Why it dies.** A forward needs a counterparty and collateral; the collateral is a coin balance posted by the seller or buyer, which is a coin bond, which is refused by ruling for anything the protocol touches. As an app between consenting parties with their own escrow it is allowed and the chain is indifferent. Prior art: Braidpool (in development), NiceHash (2014, an operator market). Verdict: never in protocol; watch as a third-party app. 0 hours.
+
+### 7.5 Finality as a service for other PoW chains
+
+**The idea.** Another PoW chain posts its block hashes into Igneum and treats the Igneum lock as a checkpoint; its clients refuse reorgs below the last anchored, locked hash. Igneum relies on nothing; others relying on Igneum is allowed by ruling.
+
+**Prior art.** Komodo dPoW (2018, approximate; the academy page 404'd): notary nodes write a chain's block hash into Bitcoin every 10 minutes (approximate) and protected chains refuse reorgs below it; VeriBlock Proof-of-Proof (2019, approximate; veriblock.org: "securing 1 chain", market cap USD 9 M); Babylon (Tas, Tse, Gai, Kannan, Maddah-Ali, Yu, 2022, IEEE S&P 2023: PoS chains checkpoint to Bitcoin; stake withdrawal from weeks to under 5 hours). Igneum's difference: the anchored chain gets a 90-s lock instead of Bitcoin's hour, and an offline-verifiable proof instead of an SPV path.
+
+**Game theory.** For Igneum: none; an anchor is a transaction. For the anchored chain: its safety becomes Igneum's finality, which pauses whenever under two thirds of weight signs (spec 03 3.7); an anchored chain must fall back to its own PoW during a pause and say so, which Babylon's design also requires of its consumers. A hostile Igneum majority cannot forge an anchor (it would need two thirds of weight to lock a false chain) but a third of weight can pause anchoring. Market (model, section G): at Komodo's cadence (144 anchors a day) the fee is 0.73 IGN a day, under one cent at any listed price. Revenue to Igneum: nothing material; standing: a product no PoW chain offers with proof-carrying finality.
+
+**Hostile review (Kaspa voice).** "Who are the customers? Komodo's dPoW protected a handful of Komodo-family chains and VeriBlock secures one chain worth USD 9 M. Small PoW chains that fear 51 percent (ETC, BTG, VTC in 2018 to 2020) chose checkpoints from their own developers over paying anyone." Correct; the demand is the gate.
+
+**Cost and gate.** 16 hours: an anchor contract (4), a client library that reads the lock and the proof for an anchored hash (8), a reference patch for one open-source PoW node (4). Gate: one outside chain's testnet runs the patch for a week and refuses a staged deep reorg below an anchored lock.
+
+**Per tier.** Nothing changes for any Igneum miner or holder; an anchored chain's miners get a 90-s checkpoint they did not vote for, which their community must accept (the Komodo precedent: accepted by chains that chose it).
+
+**Verdicts.** Cryptographer: prototype (sound, and the first external use of the lock). Consensus engineer: watch (demand first). The miner: watch (no miner cares). Economist: watch (USD 0.004 a day per customer at the floor is standing, not income).
+
+### 7.6 The hourly program as a standing public hardware benchmark with a leaderboard
+
+Frontier 3.16 (do now, 10 hours) publishes the corpus; the leaderboard is the product on top: per card model, per vendor, per driver, the median rate and joules per hash across the hour's variants, from the fleet library and opt-in Ember submissions, with the bit-exact fingerprint per entry. Prior art: Geekbench (2007, approximate), hashrate.no and WhatToMine (2018 onward, approximate) as operator tables; none continuous on a random kernel stream. New as a continuous random-kernel benchmark. Game theory: a submitter lies about its rate; the fingerprint proves bit-exactness not speed, so self-reported rates are labelled and the fleet's measured rows are the reference tier. Cost 8 hours on top of 3.16. Gate: a public page with the eleven measured cards (prover-tiers-real-cards.md) as the reference tier and opt-in rows beneath. Verdicts: do now (all four; the miner: "a leaderboard is the first thing a mining YouTuber screenshots").
+
+### 7.7 Proof of unique card: count machines, not keys
+
+Dead, and the reason is the design's own: nothing in consensus counts nodes, keys or cards (spec 3.1 W6, ledger F17), so a count of machines would be a Sybil surface the design removed on purpose; and a chip emulates any fingerprint it has been shown (frontier 4.3's Monero attack). What the design does count is blocks, and a card's blocks are its weight. Verdict: never. 0 hours.
+
+### 7.8 Shard proving as the on-ramp: a proving-only key earning pool income without a card
+
+Dead by the sortition rule: shard assignees are drawn by W2 weight (spec 7.2 step 2); a key with no blocks has no weight and is never drawn. What a proving-only key can do today: claim shards after the exclusive window (spec 7.2 item 4) and prove external jobs under the pool protocol's bonded key route (work-stake section 5, the prover row). That is the on-ramp and it exists. Verdict: never as a rule change; the two existing routes stand. 0 hours.
+
+### 7.9 Miner-signed release: 95 percent of weight signs the release hash
+
+Compare horizon rank 13 (reproducible-build attestations, N of M builders, 12 hours). A weight signature says "we RUN this hash", not "we BUILT it", and running is what the 95 percent class signal already measures (the object byte in the header version). So the idea is the P2 signal applied to a binary hash instead of a class byte: a header bit per release. Prior art: BIP9's version bits (2015) for rules, not binaries; no chain signals binary hashes (approximate). What it adds: a chain-readable "share of weight on release X" that Ember can show beside rank 13's "N builders reproduced X". Cost 4 hours (a release-hash field in the coinbase, tallied by the explorer, no consensus effect). Game theory: lying costs nothing and buys nothing; it is a statistic. Verdict: watch, fold into rank 13's display. Cryptographer: watch. Consensus engineer: do as a coinbase field, 4 hours. The miner: watch. Economist: watch.
+
+### 7.10 An energy-price oracle from miners' own signals
+
+**The idea.** Each producer carries its electricity price in its coinbase; the window's weighted median is the chain's energy price, free of any oracle operator.
+
+**Prior art.** Chainlink and the oracle networks (2017 onward, approximate); frontier 3.5's miner-voted dials (Ethereum's gas-limit vote, geth `VerifyGaslimit`); no PoW chain carries a price field (approximate).
+
+**Game theory.** A field nobody is paid for and nobody is punished for lying in is noise; a field that feeds a price (the job reserve of horizon rank 7, "measured proving electricity per pgas at the published settlement rate") is a field miners overstate, bounded only by the customer's bid, which rank 7 already makes the price. So the oracle is either noise or a lever on the job price that the bid neutralises. The honest use is statistical: the miner community lead's hardware-economics model wants real tariffs, and Ember's opt-in telemetry (the tariff field of phone-app 4.1) gives them off-chain with no consensus bytes.
+
+**Verdict.** Never in consensus; an opt-in Ember statistic. 2 hours for the telemetry line. All four personas: never in protocol.
+
+### 7.11 A first-block bonus per new key, Sybil-bounded by dust
+
+**The idea.** A key's first block above dust pays a bonus B, to welcome newcomers; the signing bonus of vote-or-burn exists, so this would be the second bonus.
+
+**Game theory (model, section F).** Dust is 100 blocks a window. A 10 percent miner makes 259,200 blocks a window and can keep 2,592 keys above dust, each collecting B once: at B = 100 IGN that is 259,200 IGN a window, 1 percent of its subsidy, for free (weight and sortition are per block, so the split costs it nothing but its own vote's convenience; the pool spec's one-key rule is a client default, not a consensus rule). A bonus large enough to matter to a newcomer (10 blocks, 1,000 IGN) is a 10 percent raise for every miner willing to run 2,592 keys. The dust bound makes the Sybil expensive in KEYS and free in HASH, and keys are free. Verdict: never. 0 hours. The miner: "an instamine with extra steps".
+
+### 7.12 A cross-vendor parity bounty
+
+Dead by ruling (no device bounty): a payment conditioned on a card model is a device bounty whatever it is called. What the design does instead is measure (the eleven rented cards, the ladder's per-rung 5 percent rule) and publish. Verdict: never. 0 hours.
+
+### 7.13 In-protocol insurance against reorgs for exchanges
+
+**The idea.** An exchange that credited a deposit later reversed by a reorg is made whole from a protocol pool.
+
+**Prior art.** None shipped in any protocol (this lane found no primary page; approximate). Off-chain: exchange confirmation policies; Nexus Mutual-style cover for contracts (2019, approximate), not for reorgs.
+
+**Why it dies.** Who pays? A protocol pool is either emission (a transfer from miners to exchanges, which the miner persona rejects on the Decred and Ethereum precedents in vote-or-burn section 2) or the proving pool (a transfer from provers, who did nothing wrong). The design's own answer is stronger than insurance: a certified checkpoint cannot be reversed (51-percent.md section 2), the four-state rule credits on "finalised" (ledger P17), and the exchange guidance says confirm at the lock or at 12 hours during a pause (horizon rank 16). Insurance is only wanted where finality is paused, and during a pause the only reorg-capable party is a hash majority with no slashable bond, by ruling. Verdict: never; the guidance is the product. 0 hours.
+
+### 7.14 Pause insurance from the proving pool
+
+Dead: it pays the wrong people or nobody. During a pause the silent third earns its subsidy (51-percent.md: "free to hold while silent"); redirecting pool income to the signing keys is the signing bonus's job (8 of 80 points) and to holders is impossible (no mechanism pays holders). Vote-or-burn priced the pause at 3,103 to 6,206 IGN an hour at 34 percent silent and found a deposit worth attacking covers either; LEAVE and weight-gated fork choice close the line. Verdict: never. 0 hours.
+
+### 7.15 Proof of latency: rewarding low-latency relays
+
+The arXiv search for "proof of latency" this morning returned five unrelated papers and none on relay rewards; FIBRE (2016) relays unpaid. Timing is unverifiable in consensus (section 1.4) and the DAG already pays for latency in blue blocks (under 2 percent red at 1 block/s, run B). A relay reward would need a clock and a Sybil-proof receipt, and it has neither. Verdict: never. 0 hours.

+
+Three "do now": ranks 1, 2, 3 (34 hours in all, plus the 36 of rank 19 and frontier 3.8 they sit on). Three "prototype": ranks 4, 5, 6 (42 hours). Everything the brief hoped was a protocol invention in sections 1, 2 and 4 is dead on a number this lane ran: 108 ms (the outsourcing fetch), 0.61 to 76.5 GB a day (challenge answers), 14.6 to 146 GB a day and 5 to 50 cores (in-protocol shares).
+
+---
+
+## 9. The honest answer
+
+Igneum's revolution is the combination already built, not any one new item. The pieces that exist in code or on a branch today and that no shipped proof-of-work chain has together: a random-program GPU hash whose dataset is the chain's own state (class v5, hash rate unchanged at 63.08 MH/s, verifier +0.11 to 0.21 ms), miner-only finality by 30 days of blue blocks with no stake (a lock 63 to 93 s after a checkpoint; 51 percent never reaches two thirds while honest miners mine), that finality carried inside the execution proof as 494 bytes a phone verifies (finality-in-proof), a bond for proving jobs made of 30 days of public work and no coin (work-stake: 2,793 IGN at risk for an 8 GB card at 100 GH/s against a 0.0015 IGN coin bond), a tail that keeps a 24-hour attack at about twelve days of emission in every year, and a pool protocol in which the operator holds no key and no vote.
+
+This lane tested fourteen candidates for the next thing and found two small ones worth building now (the offline proof in a QR, 8 hours, and heat mode, 6 hours), one Ember line (miners' nodes serve the proof, 4 hours), and three prototypes (a weight-backed peer directory that bounds an eclipse at 1.8e-4 for a 34 percent attacker, a verifiable payout contract for pools, and finality as a service for other chains). Every candidate that would have changed consensus died on a measured number: proof of serving on a 108 ms fetch, in-protocol shares on 14.6 GB a day, propagation receipts on the absence of a clock. The next genuinely new thing is the first offline-verifiable proof-of-work finality object in a user's pocket, and it is packaging on what is already built.
+
+---
+
+## 10. Three headline findings for the coordinator
+
+1. Every "hashing useful to the chain" variant beyond class v5 is dead on one number: a key with no state answers an availability challenge in about 108 ms over a 100 ms link, so any deadline over one block makes the proof "someone served", and the reward slice it would gate (2 to 8 of the 80 points, 17 to 69,120 IGN a day by key size) pays for what the lottery already compels.
+2. An in-protocol pool is FruitChains (2016) and it costs every node 14.6 GB a day and 5 cores at 10,000 miners on a 10-s share (146 GB and 50 cores at 100,000), so the finished form is the shipped pool v0 plus a verifiable payout contract (SmartPool 2017 shape, 16 hours, 32 B per round on chain).
+3. The three things worth doing now total 18 hours and change no consensus rule: an offline-verifiable 786 B finality object in a QR (260 B Groth16 + 494 B public values + 32 B key id, under a version-40 QR's 2,953 B), Ember heat mode (a 300 W card breaks even against a UK gas boiler or COP-3 heat pump at 5.3 p an hour earned, and is free against a resistive heater), and every miner's node serving that proof to phones.

+# The Igneum Mission
+
+Written 7 October 2026, morning UK, by the mission coordinator (branch `mission`, worktree `igneum-wt-mission`) on the project lead's order of the same morning, verbatim: "i dont want to get stuck in a loop here where we keep finding and adding features and security so im going to give you one last mission, deep deep dive into the past and look far into the future, what has been done, what hasnt been done, what has been started but not finished, what can we invent and what can we reinvent to honestly make the perfect gpu network that will be noticed as the revolution that everyone is waiting for."
+
+This is the last research round. Its output is the closed list in section 2. After it the project stops researching and ships. Five lanes ran in parallel and each has its own file with sources and a verdict table: `past.md` (lane 1), `unfinished.md` (lane 2), `future.md` (lane 3), `invent.md` (lane 4), `reinvent.md` (lane 5). Every number below names its lane; the lane file names the source or the model. Hours are agent hours. Nothing on the live devnet was touched and no build or hash measurement was run for this document.
+
+## 1. One page for the project lead
+
+**What has been done.** Of 31 GPU-mined chains since 2011, 8 lost the GPU lane to a chip, 7 closed it by choice, 10 died on price or a rental attack; the 6 still GPU-only pay USD 0.22 to 0.71 a day per RTX 3080 (lane 1). In 20 miner posts the wants were hardware that keeps its value, income without a cliff, a fair supply. Igneum answers the supply in full (no premine, no fund, no fee to any team), the hardware with a measured 2.1x chip bound and the N ladder, the cliff with a monthly glide and a 1 percent tail. Finality by 30 days of blocks, proving as the reward, the leave item and the signing bonus are built or approved for the testnet genesis.
+
+**What has not been done.** Nobody on those forums asked for finality, a DAG or proofs; they asked for a card that keeps its value, a bill that gets paid and a coin that sells. The front page leads with the hash, the earnings page shows £0.00, a fresh install opens with two operating-system warnings and ends its first hour without one number the miner came for, and no proving customer has signed, so the coin has Ergo's 2023 exposure: a thin market. These gaps are hours, not protocol.
+
+**Started and not finished.** Three designs sit on branches: class v5 (the dataset is the chain's own state), finality inside the segment proof, work-stake (a bond of 30 days of work, no coin). Across the industry (lane 2), every useful-work scheme that passed cheap-verify did so by making the work useless, no pool without an operator exists on any chain but Monero, and every proof-of-work finality that held was a second validator set bought with coins. Lane 4 tested whether anything new in consensus beats these; each died on a number: proof of serving on a 108 ms fetch, in-protocol pool shares on 14.6 GB a day per node at 10,000 miners, propagation receipts on the absence of a clock, proof of following because the epoch seed plus class v5 already is one.
+
+**What we invent.** One thing, and it is packaging on what is built: the first offline-verifiable proof-of-work finality object: 786 bytes in a QR a phone verifies in airplane mode, served by every miner's node. No PoW chain has put finality in a user's pocket. Beside it, two genesis bytes the future demands (lane 3): a signature-scheme byte with a key-succession slot, because a post-quantum vote at 8,192 voters costs 57 GB a day unaggregated and the flip must be signalled before a machine exists; and a cache-size rung on the ladder, because a 256 MB consumer cache is a 2 to 3x shortcut.
+
+**What we reinvent.** The miner's first month. The 30-day vote window is a level system no chain has, and it is free: first block, 100 blocks for a vote, a signature in a checkpoint, 30 of 30 days, rank by weight, a signing streak. Every rung is a chain fact from one RPC; a renter cannot top it inside 30 days; no fund pays for it. Lane 5 priced the first month at about 35 hours: the Poisson count-up before the first block (an 8 GB card at 100 GH/s waits 1.6 hours expected), the block card, earnings in IGN first, the weight leaderboard, the hardware census. In a 105-post Reddit sample the miner's own posts rise highest ("my card paid for itself" at 777 times the room median against 66 for the network's milestone), so every shareable surface carries the miner's card, rank and days, never the project's number.
+
+**The honest answer.** Igneum's revolution is the combination already built plus two new things: the finality object in the pocket, and the ladder shown everywhere. No shipped chain has the combination: a random-program GPU hash whose dataset is the chain, miner-only finality with no stake that 51 percent never reaches, that finality inside the execution proof, a work bond with no coin, a tail that holds a 24-hour attack at twelve days of emission in every year. Twelve items, about 290 agent hours, no new consensus rule beyond the three cut branches.
+
+### Decisions owed from the project lead
+
+The cryptanalysis entity and prize; the signing certificates (lane 5); the signed proving customer as a mainnet gate (lane 1); the H100 and A100 hash measurement on rented pods (lane 3).
+
+## 2. The closed list
+
+Twelve items, in build order. "In flight" names the lane or branch that holds it. Hours are the remaining agent hours; a gate is what must be true before the item is called done. Nothing is added to this list without removing something.
+
+| # | Item | State | Hours | Gate |
+|---|---|---|---|---|
+| 1 | The testnet genesis re-cut as approved | in flight (ship lane) | 0 new | the go checklist |
+| 2 | Finality in the pocket: finality in the proof, the 786 B object, every node serves it, the browser verifier | in flight (fin-proof) plus new | 68 | a phone in airplane mode verifies a printed QR and refuses a one-byte change |
+| 3 | Class v5, the dataset is the chain, and nothing wider | in flight (class-v5) | 16 | the fast-time harness across a day boundary; Devnet 2 across a real day |
+| 4 | Weight-gated deep fork choice before mainnet | in flight (horizon rank 4) | 16 | a 51 percent fresh-key fork from 15 min back refused by every honest node |
+| 5 | Work-stake: the job bond made of 30 days of work | in flight (work-stake) | 24 | 1,000 posted jobs, every injected miss forfeits, zero honest forfeits |
+| 6 | The ladder shown everywhere: the miner's first month | new (lane 5) | 35 | a Devnet 2 key walks every rung on screen; first share within 10 minutes in 9 of 10 fresh Windows installs |
+| 7 | Heat mode, the region and price prompt, the cost-against-rent line | new (lanes 3, 4) | 10 | a set temperature held within 1 degree for 4 h on PC 1 while hash follows the duty cycle |
+| 8 | Genesis forward-compatibility: the scheme byte, key succession, the cache rung | new (lane 3) | 10 | the digest test; a vote item with scheme 1 refused by every node until the signal |
+| 9 | A second proof system on the active list and the one-third stop switch | new (frontier I4, lane 3) | 24 | 1,000 segments agree across both systems; one injected bad proof disagrees and pays nothing |
+| 10 | The launch pack: gates and text, no protocol | new (lanes 1, 3, 5) | 15 | every gate line in testnet-go.md with its check |
+| 11 | The pool finished: pool-0 with member keys at 1 percent, TLS, the share sidechain with no operator | new (lanes 2, 4, 5) | 60 | 100 members on the fast-time network paid by the coinbase rule from a share chain with no operator key; the first on a DAG chain |
+| 12 | The weight-backed peer directory | new (lane 4, prototype) | 10 | a 34 percent attacker eclipses under 0.1 percent of 1,000 fresh starts |
+
+### 2.1 The testnet genesis re-cut as approved (in flight, ship lane)
+
+What it is: one cut with 18 decimals, `EmissionSchedule::TESTNET_1` (100 IGN a block, a monthly glide with a two-year half-life, a 90-day ramp from 10 percent, a 1 percent tail from year 11.4), and the switches on from genesis: proof verification in consensus, the leave item, the signing bonus at 1,000 bps, finality v3, the latency ladder at rung 0. the project lead approved it on 7 October 2026, 09:3x UK (ledger-decisions.md).
+Why it is right: lane 1's verdict rows 4 and 5 (the cliff and the premine) are answered by it in full; lane 3's tail row holds to year 200.
+Evidence: tail-emission.md one page; vote-or-burn.md section 5; ledger-decisions.md 7 October.
+Cost: 0 new hours; the ship lane's own plan.
+Gate: the go checklist (`docs/plans/testnet-go.md`); nothing mines until the word.
+Order: first; every later item lands on this genesis.
+
+### 2.2 Finality in the pocket (in flight on `fin-proof`, plus three new parts)
+
+What it is: the weight table carried inside the recursive segment proof (W2 updated one mergeset per segment, the BLS certificate verified in the guest, 494 B of public values), then three parts this mission adds: a Groth16-wrapped proof as a 786 B object (260 B proof, 494 B public values, 32 B key id) in a QR or URL that a phone verifies offline; every miner's node serving the latest object by default (an Ember line, unpaid); and the WebAssembly verifier in the tab (horizon rank 19).
+Why it is new: no proof-of-work chain has an offline-verifiable finality object; the closest shipped forms are Mina's recursive state proof (2021) and Helios's committee light client (2022), both online and neither over proof of work. Lane 4 section 6 and 3, persona verdicts do now, do now, prototype, do now.
+Evidence: finality-in-proof.md sections 1 to 5 (level 1 of the blue-set check designed, level 0 in the prototype); the certificate half verifies in 58 to 68 ms warm in a browser (bench-log round 6); SP1 light verifier 0.032 s on a Mac core; a version-40 QR holds 2,953 B.
+Cost: 40 for the fin-proof remainder (level 1 of 5.2, the cycle counts of section 6.1 on the box, the 5090 prover time on a pod), 8 for the QR object, 4 for the Ember line, 16 for the WASM verifier. 68.
+Gate: a phone in airplane mode verifies a printed QR and refuses a one-byte change; "locked, voter set verified" on cellular from a miner's node; a block proof verifies in the tab under 500 ms on a laptop.
+Order: second; it is the one invention and it needs the genesis of item 1 for the pinned aggregator id.
+
+### 2.3 Class v5, the dataset is the chain, and nothing wider (in flight on `class-v5`)
+
+What it is: each day's dataset built from the execution state at a reference block an hour before the day; a card without the state builds every item wrong. The branch widened it to a per-window refresh (section 2a of its page). This mission's ruling: no further widening. Lane 4 tested proof of following, serving, propagation and state availability as additions and found each dead on a number: a key with no state answers an availability challenge in about 108 ms over a 100 ms link, so any deadline over one block proves only that someone served; propagation receipts need a clock the DAG does not have; the epoch seed plus the state root already commit to the chain's recent blocks, so proof of following is class v5 by another name.
+Why it is right: hash rate and watts unchanged within noise (63.083 against 63.088 MH/s, 205 to 208 W on a 4090), build +1.4 ms, verifier +0.11 to 0.21 ms per unit; it removes the f = 0 recompute chip as a category and the stateless pool miner.
+Evidence: class-v5-stored-state.md; new-pow.md 5.2 and 6; invent.md sections 1 and 8 rows 11 to 15.
+Cost: 16 (the 4090 rows owed in section 7, the exec snapshot wire version 2, the GPU hosts' leaf buffer, the spec text).
+Gate: the fast-time harness crosses a day boundary with the roots agreeing on every node and the stateless node's miner at 0 accepted blocks; Devnet 2 across a real day boundary; then the 95 percent signal with a floor.
+Order: third; it rides the class-signal machinery item 1 ships.
+
+### 2.4 Weight-gated deep fork choice before mainnet (in flight, horizon rank 4)
+
+What it is: a tip whose fork point is older than D (10 min of past-median time) is a fork-choice candidate only if the keys that built it hold at least a third of the weight table at the fork point.
+Why it is right: lane 1's verdict row 6: rented hash reorganised Bitcoin Gold, Vertcoin and Musicoin for USD 70 k to 18 M; Igneum's finality bounds this after day 20 and not before, and the first 20 days are when a new chain is watched. The 51 percent paper prices a 12-hour double spend during a pause at USD 146 at 1 GH/s today.
+Evidence: 51-percent.md section 5 rank 2; horizon rank 4; past.md section 4 row 6.
+Cost: 10 to 16.
+Gate: fast-time: a 51 percent fresh-key fork from 15 min back is refused by every honest node; a one-third-weight fork is accepted; partition heal unchanged.
+Order: fourth; before the public testnet opens, because the testnet is the first chain outsiders can rent against.
+
+### 2.5 Work-stake (in flight on `work-stake`)
+
+What it is: a vote key may claim an external proving job only if its next window of pool income covers the job's value; a miss, refusal or forgery forfeits that income for one window, the buyer's fee refunded first, the rest to the pool. No balance moves; no coin is posted. The spec sentence lands first: "no coin stake; the only thing at stake is 30 days of public work."
+Why it is right: a bond nobody can buy (2,793 IGN at risk for an 8 GB card at 100 GH/s against a 0.0015 IGN coin bond); every attack in its section 6 fails on the window arithmetic.
+Evidence: work-stake.md sections 3 to 7; frontier 3.2 and 4.1.
+Cost: 24 (orders carried in blocks, the term unwound on reorg, the finality report wired to `judge_at`, the snapshot field, the deadline floor).
+Gate: Devnet 2: 1,000 posted jobs with 10 percent injected misses, every injected fault forfeits, zero honest keys forfeit; a 60 s partition across 100 deadlines forfeits nothing.
+Order: fifth; it needs the job market of spec 5.4, which the first customer (item 10) needs.
+
+### 2.6 The ladder shown everywhere: the miner's first month (new, lane 5)
+
+What it is: the 30-day vote window as the status ladder on every surface, and the first month's moments built around it. The rungs: first block; 100 blocks and "your key has a vote"; "your signature is in checkpoint K"; 30 of 30 days, full weight; rank by weight; the signing streak; "your card proved shard N of block M". The parts: the Poisson count-up before the first block ("a card like yours finds a block about every 1.6 hours on today's network; chance so far 31 percent"); the block card with a locally drawn PNG and the explorer link; Earnings in IGN first (6,912 IGN a day for a 100 MH/s card at 100 GH/s at the full rate) with a typed price never fetched; the weight leaderboard on `/live` (weight, never hashrate, so a renter sits at the bottom for 30 days); the public address profile behind an opt-in; the hardware census on `/miners` from the hourly program's per-card timings (frontier 4.3); #first-blocks and the Voter and Window roles granted from `getFinalityWeights`.
+Why it is the right reinvention: lane 5's archive sample shows the joy posts are the first block, the first payout and the rig photo In a 105-post sample the miner's own posts rise highest: "my card paid for itself" at 777 times the room median against 66 for the network's milestone.; Helium, Chia, Ethereum 2017 and Kaspa 2022 each had a hook, a daily ritual and a status surface, and each status surface was a company number or a hashrate a renter could top. Igneum's is a consensus fact. Nobody has it.
+Evidence: reinvent.md sections 1, 2, 3.2 to 3.7, 7; the solo-block expectations per tier at 100 GH/s and 1 TH/s (an 8 GB card: 1.6 h and 16 h; it never reaches the vote line at 1 TH/s, which is why the pool is item 11; the 100-block dust line means an 8 GB card never votes past about 500 GH/s, a question for the finality lane and a watch item, not a list item).
+Cost: 35 (Poisson line 2, block card 4.5, earnings 6.5, ladder 6, leaderboard 3, profile 3, census 4, Discord 5, the first-hour timeline on `/miner` 2).
+Gate: a Devnet 2 key walks every rung on screen in a view test; every number on the tab names its RPC field on hover; "first share within 10 minutes of download in 9 of 10 fresh Windows installs" published on `/evidence`.
+Order: sixth; it is the first thing the first outside miner sees.
+
+### 2.7 Heat mode, the region and price prompt, the cost-against-rent line (new, lanes 3 and 4)
+
+What it is: Ember holds a room temperature or a schedule and the hash follows the duty cycle; a per-region electricity-price prompt with a banned-region line ("mining may be restricted where you are; you are responsible for checking"); the Earnings tab's cost line against the measured rental rate so a miner sees when rented hash undercuts their card.
+Why it is right: a 300 W card as a heater breaks even against a UK gas boiler or a COP-3 heat pump at 5.3 p an hour earned and is free against a resistive panel (lane 4 section 5); the heating season credits about a third of a UK or EU miner's bill (lane 3 section 4); lane 3's 2031 row says retail-power tiers leave first when idle datacentre hash sets the rent, and the heat mode keeps winter home miners on. Prior art is Heatbit (2022), 21energy and Qarnot; new only as a chain client's feature, which is the point.
+Evidence: invent.md section 5 and rank 2; future.md sections 3, 4 and 10.
+Cost: 6 heat mode, 2 region prompt, 2 the rent line. 10.
+Gate: a set temperature held within 1 degree for 4 h on PC 1 while hash follows the duty cycle; the prompt shows the right banned list for a Russian region; the rent line reads the bench-log rate.
+Order: seventh; app only, no digest, ships in any cut.
+
+### 2.8 Genesis forward-compatibility: the scheme byte, key succession, the cache rung (new, lane 3)
+
+What it is: three genesis fields. A `sig_scheme` byte in the vote item and the key reveal (0 = BLS12-381 today), so a post-quantum scheme flips by the 95 percent signal and not by a fork. The key-succession item (W5, unimplemented on the node) so a key can hand its weight and its forfeit term to a successor once, which is the migration path. A cache-size rung on the signal ladder beside N, because a consumer last-level cache at the cache size (256 MiB) gives that card's owners a 2 to 3x shortcut (chip-model-v3; consumer LLC is 96 to 128 MB today, datacentre 256 MB). The class-group VDF's quantum fallback is flagged, not sized.
+Why it is right: naive ML-DSA-44 votes at 8,192 voters cost 19.4 MB a checkpoint and 57 GB a day; with 250x SNARK aggregation about 223 MB a day; a cryptographically relevant quantum computer is "quite possible (28 to 49 percent)" within ten years (Global Risk Institute 2025) and NIST deprecates ECDSA and EdDSA after 2030. The flip is signalled the year of deprecation, not the year a machine appears; the byte costs nothing now and a fork later.
+Evidence: future.md section 7 and 10; finality-in-proof.md 7 (W5 absent).
+Cost: 10 (the byte and the digest test 4, the W5 item 6, the rung 1 inside the ladder code, the spec text).
+Gate: the digest test; a vote item with scheme 1 refused by every node until the signal; a succession carried once and refused twice in the fast-time harness.
+Order: eighth; genesis fields must land before item 1's final cut, so this is scheduled with it and listed here for its own gate.
+
+### 2.9 A second proof system on the active list and the one-third stop switch (new, frontier I4 and lane 3)
+
+What it is: a second zkVM behind the `ProofSystem` trait (RISC Zero or OpenVM) proving the same segments on one fleet box as a shadow; a disagreement between the two on any segment is a public alert and the pool stops paying on proofs until 1/3 of weight signals which system to trust. Full nodes keep the native-execution veto whatever happens.
+Why it is right: three soundness-class events across SP1 and RISC Zero in 18 months (lane 3 section 5); the veto protects full nodes and nothing protects a light client or the proving pool; lane 3's death row 4 is this.
+Evidence: future.md sections 5 and 9; frontier I4; ledger P7 and D6.
+Cost: 24.
+Gate: 1,000 segments agree across both systems; one injected bad proof disagrees, pays nothing and raises the alert.
+Order: ninth; before any phone trusts item 2's object.
+
+### 2.10 The launch pack: gates and text, no protocol (new, lanes 1, 3 and 5)
+
+What it is: lines added to `docs/plans/testnet-go.md` and the litepaper, each with its check. Gates: a signed proving customer before mainnet, with the weight of the Devnet 2 gate; per-tier income published at three prices (USD 0.005, 0.02, 0.10) before the testnet, per the consequences rule; the launch-week hash-origin report (key counts, pool shares, fleet shares) from the observer, daily for the first 90 days; the first 100 keys, the first 1,000 independent keys (the X5 definition), the first pool not run by the project, the first outside-reproduced benchmark, the first block from a card the project does not own; signed and notarised installers (Developer ID, Authenticode) with the measured first-share time per release. Text: the three wants on the front page and finality on page two; "a block pays its miner whether or not anyone buys a proof that day"; the eight regulatory sentences of lane 3 section 8.3 (no issuer, no sale; the sustainability indicators per era; no price language; the pool holds no balance; no privileged key), labelled "not legal advice; counsel is engaged".
+Why it is right: lane 1's shape (income halves 60 to 120 days after a peak, under USD 0.10 per kWh within 6 to 18 months, 50 to 100 percent of hash gone in 90 days) and its rows 2, 4, 7 and 9; lane 5's install findings (SmartScreen warns on any file without reputation); lane 3's regulation rows (MiCA 4(3)(b) exempts block-reward assets; the UK regime from 25 October 2027 covers platforms and custody, not mining).
+Evidence: past.md sections 3 and 4; future.md section 8; reinvent.md 3.1 and 4.1.
+Cost: 15, plus the project lead's certificates and the customer's signature.
+Gate: every gate line in testnet-go.md with its check; the forbidden-strings check passes on the new text; the hash-origin report posts on Devnet 2 for seven days before the testnet go.
+Order: tenth; text and gates can land any hour, and the customer gate is the one that takes longest.
+
+### 2.11 The pool finished (new, lanes 2, 4 and 5)
+
+What it is: pool-0 run by the project at the testnet go with the member's vote key in every header (the pool holds no weight and no vote), a 1 percent fee published beside the dev fee, PPLNS with a round every 60 s; TLS before the public testnet (spec 9.3) and the pool page rows Q69 to Q73; then the pool without an operator: a P2Pool-style share sidechain in the pool crate, shares forming a 10-second chain committed in the coinbase extra data, the window's payout computed by every node from consensus data as the 20 percent already is, no balance and no operator key, every member running the node the design already assumes. Lane 2's verdict: the finished form is Monero P2Pool's, not SmartPool's (SmartPool's on-chain claims died on gas, and at 1.35 ms per share verification a sampled contract would still need the zkEVM to re-derive a warp unit per sampled share); lane 4's in-protocol pool (shares inside blocks, every node verifying every share) stays refused at 14.6 GB a day per node.
+Why it is right: no pool without an operator exists on any chain but Monero (P2Pool at 7.7 percent of hash, 3,520 miners, 0 percent fee; Ocean 2.05 percent of blocks with 85 percent through DATUM; Stratum V2 job declaration at 1 block in 52,297); Igneum already holds the three objects that make one cheap (the vote key in the header, the 20 percent paid by sortition, the coinbase extra data), and nobody has built one on a DAG chain. An 8 GB card at 1 TH/s finds a solo block every 16 hours and 23 percent of its days have none, so the first-month ladder of item 6 depends on a pool from about 1 TH/s.
+Evidence: unfinished.md section 5 (5.2, 5.3) and headline 2; invent.md section 4 and rank 13; reinvent.md 3.5 and 1.4; pool.md; spec 09.
+Cost: 60 (TLS 8, the pool page rows about 12, the share sidechain about 40).
+Gate: 100 members on the fast-time network paid by the coinbase rule from a share chain with no operator key, a withheld share earning nothing, a member's dropped share provable from its own log; the first payout inside two minutes of the first share for an 8 GB card on Devnet 2.
+Order: eleventh; pool-0 and TLS before the testnet go, the share sidechain before the network passes about 1 TH/s.
+
+### 2.12 The weight-backed peer directory (new, lane 4, prototype)
+
+What it is: a coinbase section where a key above dust may publish its node's address; a fresh node dials from that list weighted by 30-day weight, beside the DNS seeds.
+Why it is right: lane 4's model E bounds an eclipse by a 34 percent attacker at 1.8e-4 with 8 outbound peers and 3.2e-8 with 16; prior art (DNS seeds 2011, discv5 2019, Heilman's eclipse paper 2015) weights nothing by work; lane 3's 2031 death row (weight concentrating in hosting firms) is first seen through such a list.
+Evidence: invent.md section 7.1 and rank 4; horizon rank 9 (the peer floor it extends).
+Cost: 10.
+Gate: a fresh node with genesis peers only reaches 8 outbound from the directory; a 34 percent attacker eclipses under 0.1 percent of 1,000 fresh starts; the NAT fraction measured on the fleet.
+Order: last; a prototype, dropped if the NAT fraction makes the list useless.
+
+## 3. Rejected, with the one line that killed each
+
+| Idea | The line |
+|---|---|
+| A pool inside the protocol (shares in blocks, no operator) | FruitChains (2016): 14.6 GB a day and 5 cores per node at 10,000 miners on a 10 s share; 146 GB and 50 cores at 100,000 |
+| A reward slice for serving state or data | a key with no state answers in 108 ms over a 100 ms link; it pays for what the lottery already compels |
+| Proof of propagation receipts | no consensus clock; 94 to 376 MB a day of receipts; GHOSTDAG already is a proof of propagation |
+| Proof of following beyond class v5 | the epoch seed and the state root already commit to the recent chain |
+| A first-block bonus per key | a 10 percent miner collects it 2,592 times a window: an instamine with extra steps |
+| Reorg insurance for exchanges, pause insurance from the pool | no slashable payer by ruling; the lock is the product; the pool pays the wrong people |
+| Proof of latency, proof of unique card, an energy-price oracle, hash-rate futures in protocol | no clock; nothing counts cards by design; a lever the bid neutralises; needs a coin bond |
+| Finality as a service for other chains | kept as a demand-gated prototype only; no customer named, so not on the list |
+| The weight-aged reward rule (pay per block falls when hash arrives faster than the weight) | a 30-day income ramp on every honest newcomer, which the first-month ladder cannot afford; revisit only if weight by hosting provider passes a third |
+| Mining is proving; useful work in the hash | 2.9 MB of openings per block, a 32 to 40 ms verify against the 10 ms gate; Aleo's fastest-prover-wins |
+| Proving others' chains as the main income | all of Ethereum L1's proving is about USD 36 a day against USD 13,700 of year-1 emission |
+| Vote-or-burn | 70 to 80 percent respect against the 95 percent test; the signing bonus is on at genesis instead |
+| Dormant-coin rent, any holder penalty, a device bounty, a coin stake, Bitcoin anchoring, privacy | refused by ruling |
+| A hardware wallet verifying proofs on the secure element | a bn254 pairing on a Cortex-M class element is seconds to minutes; the companion verifies |
+| A compute market for unverifiable work | an escrow without a verifier is a trust-me payment with lower fees |
+| Merged mining, multi-algo, an auxiliary chain | A child inherits its parent's pool concentration and loses its say in rules; a second hash lane splits the weight table and the DAA (Myriad, Verge, DigiByte); the one merged-mining shape with value is the share sidechain of item 11 |
+| Gamification paid from a fund, referral in coins, an airdrop for anything, NFT badges, off-chain points, a rank-by-hashrate board, a top-earners board in fiat, streaks that demote | there is no fund; nothing is for sale; the rung is a chain fact; a renter tops hashrate on day one; the burn was refused |
+| Any number that needs a company server to be trusted | every number shown is reproducible from a node, or it is not shown |
+
+## 4. What this round did not run
+
+| Item | Why | Where it sits now |
+|---|---|---|
+| The H100 and A100 hash rate on rented pods | no pod rented for this round | item 10's measurement line; lane 3 section 3 |
+| The in-guest BLS and colouring cycle counts (fin-proof 6.1) | no box slot taken for this document | item 2's cost |
+| The 4090 rows for class v5 (section 7 of its page) | the pod window was the class-v5 lane's | item 3's cost |
+| Reddit, bitcointalk and the Wayback Machine | refused this environment's fetches; quotes came through search snippets and project forums | past.md section 2, reinvent.md section 1, each labelled |
+
+## 5. The closing line
+
+Nothing is added to this list without removing something. Signed, the mission programme, 7 October 2026.

+# The past, honestly: every GPU-mined chain since 2011 and what GPU miners want
+
+Lane 1 of the last mission. Written 7 October 2026 by the past lane for the mission coordinator. Scope: the history of every chain that mattered to GPU miners, what each promised, what each paid, when the GPU miners left, and what the record says Igneum should change. The ASIC side of this history (which hash fell to which chip and how fast) is already in `docs/analysis/asic-resistance-history.md` and is not repeated; this file cites it where a chip is the reason a chain died for GPUs. The emission and governance comparison against Kaspa, Monero, Ethereum and the rollups is in the Horizon economy lane (section 4.6) and is not repeated either.
+
+Every figure from a source carries a URL and the access date in section 6. Every figure from memory is labelled approximate. Reddit, bitcointalk and the Wayback Machine refuse this environment's fetches (sections 2 and 6 say which quotes came through search snippets instead). Times are UK time.
+
+## 0. Progress
+
+| Time (UK, 7 Oct 2026) | State |
+|---|---|
+| 08:05 | Read CLAUDE.md, asic-resistance-history.md, horizon-2026-10.md section 1, economy-and-utility.md 4.6 |

+| 08:49 | Writing; sections 1 to 6 landed in one pass |
+| 08:53 | Length check (258 lines, under the 300 floor); added 1a (the Merge week) and 1b (promised against delivered), split the grouped chain paragraphs, reconciled headline 1's counts against the table |

+## 1. One row per chain
+
+Income columns are USD per card per day before electricity unless stated. "Exit" is when the median GPU miner stopped earning more than electricity at USD 0.10 per kWh, or when the lane closed outright. State is October 2026.
+
+| Chain (hash) | Launch | What it promised GPU miners | Peak GPU income (card, date) | Exit income (card, date) | GPU miners left | What killed the GPU lane, or state today |
+|---|---|---|---|---|---|---|
+| Litecoin (scrypt) | 13 Oct 2011 (approximate) | Memory-hard hash mineable on CPUs and consumer GPUs; no ASIC existed (litecoin.watch) | 200 to 800 kH/s per Radeon, 2012 to 2013; USD per card approximate 1 to 5 | 2014, under power for any GPU once Zeus 28 MH/s at 800 W shipped | Mid 2014 | Scrypt ASIC (Gridseed Jan 2014, Zeus mid 2014, Antminer L3 2017). Today an ASIC chain merged with Dogecoin |
+| Dogecoin (scrypt, AuxPoW) | 6 Dec 2013 | A fun scrypt coin for the same GPUs as Litecoin | Approximate USD 1 to 3 per card, Jan to Feb 2014 | Aug 2014 | Aug to Sep 2014 | Merged mining under Litecoin from block 371,337 (28 Aug 2014); hashrate +1,500 percent in a month (Binance Research). GPUs never came back |

About 900 TH/s and about 20 million GPUs (Tom's Hardware estimate) lost 94 percent of GPU income in one block (2Miners: USD 24 M a day to USD 1.2 M) |
+| Ethereum Classic (Etchash) | Jul 2016 fork | A home for Ethash GPUs after the Merge | 70.5 to 158 TH/s in 7 hours on 15 Sep 2022 (CoinDesk), 296 to 312 TH/s inside a day | Under electricity for most GPUs within weeks; hashrate -48 percent in four days (AMBCrypto) | Sep to Dec 2022, then again as E9 Pro and Jasminer ASICs took the chain | Today 130 to 186 TH/s, ASIC-dominated; best ASIC nets USD 3.64 a day at USD 0.10 (asicminervalue) |
+| Monero (CryptoNight to RandomX) | 18 Apr 2014 | CPU and GPU mining, fork away any ASIC | Vega 56 era 2017 to 2018, approximate USD 2 to 4 per card | 30 Nov 2019: GPU performance "gets a tiny boost or degrades" (MinerUpdate) | 30 Nov 2019: 75 percent of GPU miners offline (MinerUpdate) | RandomX moved it to CPU on purpose; hashrate 300 MH/s to 800 MH/s in weeks. Qubic's rented-CPU campaign claimed 51 percent on 11 Aug 2025 with a 6-block reorg (The Block); the AFT 2026 paper finds no sustained majority and no reward edge |
+| Zcash (Equihash 200,9) | 28 Oct 2016 | "Universal accessibility" in mining (forum users' reading of the project) | USD 8 per GTX 1080 Ti, Jul 2017 (WhatToMine via 2Miners) | USD 2.63 per 1080 Ti, 6 May 2018 (2Miners) | Jun to Sep 2018 | Antminer Z9 mini announced 3 May 2018; the company stayed neutral; no fork.

On 7 Aug 2026 a header-validation flaw let blocks carry "no genuine ProgPoW work" and split the chain; RVN -19 percent (crypto.news) |
+| Ergo (Autolykos v2) | 1 Jul 2019 (approximate) | Memory-hard, ASIC-resistant, GPU-only (minerstat FAQ) | Approximate USD 3 to 4 per 3080, Sep to Nov 2021 (ERG near USD 15) | USD 0.22 per 3080 before power, Oct 2026 (hashrate.no) | Late 2022 onward | The Merge pushed it from 22 to 155 TH/s in a day (Decrypt); difficulty ate the income within weeks. Still GPU, no chip, income under power |

+
+### 1a. The Merge week, the one migration with hour-level data
+
+| When (UK) | What happened | Source |
+|---|---|---|
+| 15 Sep 2022, 07:43 | The Merge; Ethereum's last proof-of-work block; about 900 TH/s of GPU hash loses its income | Tom's Hardware |
+| 15 Sep 2022, 07:00 to 14:00 | ETC from 70.5 to 158.3 TH/s; RVN from 8.9 to 15.9 TH/s; ERG from 22 to about 70 TH/s | CoinDesk, Decrypt |
+| 15 to 16 Sep 2022 | ETC peaks at 296 to 312 TH/s (about a third of Ethereum's hash); ERG peaks at 155 TH/s (7x) | AMBCrypto, crypto.news, Decrypt |
+| 16 Sep 2022 | ETHW mainnet; the fork trades above USD 140 and falls for three years | KuCoin price history |
+| 19 Sep 2022 | ETC hashrate down 48 percent from its peak in four days | AMBCrypto |
+| Sep 2022 | Hiveon pool: 16 percent of its miners to ETC, 7 percent to RVN, the rest spread or gone | Hiveon |
+| 12 Sep 2022 (before) | 2Miners' arithmetic: USD 24 M a day of GPU income, 94 percent of it Ethereum; USD 1.2 M a day left for all GPU coins after | 2Miners, The Block |
+
+The arithmetic is the whole story: the receiving chains had one twentieth of the income and received, for a day, one third of the hash. Difficulty did the rest. The 2Miners advice of the day was to pick ETC, RVN or ERG "at least for the first days", and the first days were all there were.
+
+### 1b. Promised against delivered
+
+| Chain | The launch text (quoted or paraphrased) | What GPU miners got | Months of GPU income |
+|---|---|---|---|
+| Grin | 90 percent of blocks to the GPU hash at launch, falling to zero over two years (forum, Aug 2018) | Exactly that | About 18 |
+| Ravencoin | GPU-only, fork away FPGAs (KAWPOW, May 2020) | GPU-only for six years; a header bug, not a chip, split the chain in 2026 | 100 and counting, under power since about 2023 |
+| Kaspa | "GPU PoW", fair launch (bitcointalk ANN title) | 17 months, then chips at 20x and more per joule | 17 |
+| Karlsen | "We will ensure long-term GPU-friendly mining" (README) | A second hash in nine months to keep the promise; income under power either way | 10 |
+| Iron Fish | A GPU-mined private chain | Unknown hardware inside weeks; a GPU hash a year later | 12, then under power |
+| Aleo | Proving as mining on GPUs | USD 13.50 a day per 4090 for a few weeks, then price and pools | 3 |
+| Flux | GPU-only, "resistance to concentrated specialized-hardware advantages" | Seven years, then block production moved to nodes | 84, then closed |
+| Clore | Mine the coin that pays for GPU rental | Proof of work ended in December 2025; rental stayed | 36 |
+| Nervos | GPU-mineable launch | 16 days of 10x hashrate growth from secret chips four months in | 4 |
+
+What the table says, chain by chain, in one short paragraph each.
+
+**Litecoin.** The first GPU coin and the first proof that a memory-hard hash on paper is a compute-bound hash in a fab. Scrypt with a 128 kB scratchpad fit on a chip in 27 months. GPU miners did not vote or fork; they sold the cards. Lesson for Igneum: the dataset has to be bigger than any die the chip can afford, and the lane's own history (asic-resistance-history.md rows Scrypt) already prices this.
+
+**Dogecoin.** The only chain on the list whose GPU exit was a decision, not a defeat. Merged mining handed security to Litecoin's ASICs and the hashrate rose 15x in a month. Lesson: a small chain that shares hardware with a big one is mined by the big one's miners whenever the big one's miners choose; Igneum's hash has no big sibling, which is a feature and a cost.
+
+**Ethereum.** Seven years of GPU income, three cycles, one exit that was announced for five years and still removed 94 percent of all GPU mining income in one block. The money went to ETC, RVN and ERG for days and then to the shelf. Lesson: miners follow income, not loyalty, and an exit that is scheduled is still an exit.
+
+**Ethereum Classic.** The refugee chain. It absorbed a quarter of Ethereum's hashrate within hours and lost half of that within four days, then went to ASICs. Lesson: a chain that receives a migration gets a difficulty shock, not a community.
+
+**Monero.** Four hash forks in 20 months kept chips off and cost 85 percent of hashrate each time (asic-resistance-history.md). RandomX then chose CPUs on purpose and three quarters of the GPU miners left in a day. In 2025 a rented CPU fleet (Qubic) claimed a majority and produced a 6-block reorg; the peer-reviewed analysis finds no sustained majority and no profit. Lesson: ASIC resistance by hand is a treadmill; a majority that cannot profit still frightens exchanges.
+
+**Zcash.** The clearest record of a project refusing to fork for its GPU miners. The forum poll ran in February 2018, the Z9 shipped in May, the company stayed neutral, the GPUs left by autumn. Income per 1080 Ti fell from USD 8 to USD 2.63 before the chip arrived, because the price fell first. Lesson: the price kills before the chip does.
+
+**Ravencoin.** The one chain that forked three times and kept the GPUs for six years. KAWPOW cut hashrate 10x on fork day because the FPGAs left. Then in August 2026 a validation bug (not a chip) split the chain. Lesson: random-program hashes work; the client is the next weak point, and Igneum has one client.
+
+**Ergo.** A GPU-only hash that never saw a chip and still pays USD 0.22 a day per 3080. The Merge gave it 7x the hashrate in a day and the difficulty took the income back in weeks. Lesson: the hash is not the income.
+
+**Kaspa.** The template Igneum forked. A fair launch, a compute-bound hash, 17 months of GPU income, then IceRiver and Bitmain in the same quarter. In April 2023 a 3070 made USD 1.21 a day beside a KS2 making USD 361. The GPU share went to nothing by the end of the year while the chain prospered. Lesson: the chain can win while its GPU miners lose; Igneum's whole bet is that these two must not separate.
+
+**Grin and Beam.** Both launched in January 2019 into a bear market. Grin scheduled its own GPU lane to die over two years and it did. Beam never had a chip and still lost its miners to the price. Lesson: a launch into a falling market with a thin order book does not get a second chance; the ramp must survive a bad first year.
+
+**Conflux, Firo, Iron Fish.** Three GPU-only hashes with no chip after five to six years, each paying under a dollar a day per card. Lesson: resisting the chip buys the right to be small.
+
+**Alephium.** A sharded chain with a plain Blake3 hash, GPU-mined for about 30 months, then Goldshell shipped a 180 W box in May 2024 and a 1.25 TH/s box five months later. The GPUs were out by autumn and by 2026 the boxes themselves lose money at USD 0.10. Lesson: a chip on a small chain eats the GPUs and then eats itself; the chain gets neither back.
+
+**Nervos.** The extreme case of private hardware. Hashrate rose 10x in 16 days in March 2020, four months after launch and a month before the first ASIC was on sale; a 300-card GPU farm went from USD 410 a day to USD 4.46. Lesson: the first ASIC is always private, and the launch ramp has to assume one.
+
+**Radiant.** Said "GPU/ASIC" in its own announcement title and went to ASIC on schedule in September 2024. Lesson: a chain that invites the chip gets the chip; honest, and not Igneum's path.
+
+**EthereumPoW.** The fork that promised Ethereum mining would continue. The coin traded above USD 140 for a day and under USD 2 by 2025; the pools left for Ethereum Classic within months. Lesson: a fork keeps the code and loses the market; the market is what paid the miners.
+
+**Karlsen, Pyrin, Nomura.** Three kHeavyHash forks launched into the gap the Kaspa chips opened. Karlsen kept its README promise by changing its hash within a year; Pyrin was called a premine scam on launch day; Nomura is a title. Lesson: "the GPU version of X" is a business model with a nine-month half-life.
+
+**Nexa.** Fair launch, CPU first, the top of the profitability tables for a summer, then price. Lesson: being the most profitable coin on WhatToMine for a month is a sell signal, not a community.
+
+**Aleo.** The one chain where mining was proving. The fastest provers took the reward, the pools took the rest, the price fell from USD 9 to USD 3.40 and the GPUs left; the record also shows what miners say when insiders hold the supply. Lesson: Igneum's separation of lottery and proving is the right answer to the first half; the allocation half is answered by having no allocation.
+
+**Flux, Clore, Dynex, Qubic.** Four projects that stopped paying GPUs for hashing and told miners to rent, host or train instead. Flux moved block production to nodes, Clore ended proof of work and pays for rental, Dynex's marketplace never paid, Qubic became a hashrate broker for Monero and then Dogecoin. Lesson: "useful work" projects abandon the miner the day the useful work does not pay; Igneum's proving must be priced to clear (Horizon rank 7) or it is Dynex.
+
+**Vertcoin, Bitcoin Gold, Musicoin.** The three small chains 51 percent attacked by rented hash, between USD 70 k and USD 18 M a time. Each was GPU-only and each was attacked because it was. Lesson: a GPU chain is rentable by definition; finality has to be something hash cannot buy.
+
+**EthereumPoW, TurtleCoin, Akroma, Callisto.** Dead by price, by halt, by abandonment, by a team's money running out. Lesson: a chain with no market is a chain with no miners within a year.

+### The three wants, with counts
+
+| Want | Posts asking for it (of 20) | Evidence rows |
+|---|---|---|
+| 1. Hardware that stays useful: no chip, no FPGA, a card that games or computes when the coin dies | 10 | 1, 2, 3, 4, 5, 7, 8, 13, 16, 17 |
+| 2. Income above electricity that does not fall off a cliff | 6 | 9, 10, 11, 12, 19, 20 |
+| 3. A fair supply: no premine, no insider allocation, a coin somebody will buy | 4 | 14, 15, 18, 19 |
+
+### The three hates, with counts
+
+| Hate | Posts (of 20) | Evidence rows |
+|---|---|---|
+| A. Secret hardware on the chain before anyone can buy it | 5 | 7, 8, 13, 16, and Nervos (section 1) |
+| B. Premine, VC allocation, locked airdrops | 3 | 14, 15, 18 |
+| C. The income cliff and the dead market (an exit, a delisting, a 99 percent drawdown) | 5 | 10, 11, 12, 19, 20 |
+
+### Mapped to Igneum's design (horizon-2026-10.md section 1 and the litepaper)
+
+| Want or hate | Status | Mechanism, and the honest gap |
+|---|---|---|
+| Want 1, hardware stays useful | Partly answered | Random-program hash with hourly swaps, 256 MB dataset with 8 dependent reads, era draws from chain state, no scheduled fork (CLAUDE.md design paragraph). The chip model says 2.1x per joule at class v4 and the N ladder is a decision owed (Horizon item 4 and rank 10). Kaspa's chip was 20x to 1,200x; 2.1x is a different world, but a 2.1x chip at scale still ends home mining on power price alone. The gap is the ladder decision and a public chip model per era |
+| Want 2, income without a cliff | Partly answered | 100 IGN a block gliding 2.9 percent a month, no halving day, a 1 percent tail (tail-emission.md). No chain on this list ever had a cliff-free schedule, so this is new. The gap: every exit in section 1 came from price, not schedule, and no protocol sets price. What Igneum can do is publish the per-tier income at three prices before launch (the consequences rule) so nobody buys a card on a number that was never promised |
+| Want 3, fair supply | Answered | No premine, no dev fund, no fee to any team, 90-day ramp from 10 percent (CLAUDE.md, tail-emission.md). Aleo and Pyrin are the counter-examples and Igneum has nothing they had |
+| Hate A, secret hardware at launch | Partly answered | The ramp from 10 percent makes the first 90 days worth less to a private farm; the correlated-group detector and `security_alert` (Horizon rank 16) show it; the hourly program swap means a private FPGA bitstream has to be re-made every hour. Not answered: a private rented GPU fleet is not hardware and is allowed; Nervos's 16-day 10x rise would look the same on Igneum's charts. The gap is a published launch-week hash-origin report (pools, key counts, fleet shares) so the community sees it the day it happens |
+| Hate B, premine and allocations | Answered | As Want 3 |
+| Hate C, the cliff and the dead market | Not answered by protocol | The glide removes the schedule cliff and the proving market gives the coin a buyer other than an exchange (Horizon 4.1a), but a rollup customer paying in dollars is a contract not yet signed (Taiko is the first named customer). Until a customer pays, Igneum has the same exposure as Ergo in 2023: a good hash, a thin market |
+
+One more thing the posts do not say and the record does: nobody on these forums asked for finality, for a DAG, or for proving. They asked for a card that keeps its value, a bill that gets paid, and a coin that sells. Igneum's technical answers are to questions miners did not ask; the mission should put the three wants on the front page and the finality on page two.
+
+## 3. The earnings curve as a pattern
+
+USD per card per day before electricity. A 3080 draws about 220 W, so electricity at USD 0.10 per kWh is USD 0.53 a day; a 4090 at 400 W is USD 0.96. Where a figure is approximate it says so.
+
+| Chain | Launch | Peak month | Peak income (per 100 MH Ethash or per 3080 equivalent) | Month income fell under power at USD 0.10 | Hashrate that left in the next 90 days |
+|---|---|---|---|---|---|
+| Ethereum | Jul 2015 | Jan 2018, then May 2021 | USD 23 per 100 MH (Jan 2018, USD 0.233 per MH); approximate USD 12 to 15 per 3080 in May 2021 | Never for a 3080 before the Merge (approximate USD 1 to 2 a day in Sep 2022, over power); the lane closed 15 Sep 2022 | 100 percent of Ethereum's 900 TH/s; of the GPUs, about a quarter tried ETC and half of those left inside four days (CoinDesk, AMBCrypto); approximate 80 percent of the cards were off within 90 days |
+| Kaspa | Nov 2021 | Feb to Mar 2023 (approximate) | Approximate USD 2 to 3 per 3080 | Approximate Sep to Oct 2023 (a 3070 was at USD 1.21 in Apr 2023 as the first ASICs landed) | GPU share from near 100 percent to under 10 percent by Dec 2023 (approximate); the network's total hashrate rose the whole time |
+| Ergo | Jul 2019 | Sep to Nov 2021 | Approximate USD 3 to 4 per 3080 | Approximate Nov to Dec 2022 (the Merge took hashrate from 22 to 155 TH/s in a day) | Approximate 50 to 70 percent of the post-Merge peak within 90 days |
+| Ravencoin | Jan 2018 | Feb to Apr 2021 | Approximate USD 6 to 8 per 3080 | Approximate Nov 2022 (the FTX month); a 3080 now loses USD 0.13 to 0.31 a day | Approximate 40 percent of the post-Merge peak (15.9 TH/s) within 90 days |
+| Aleo | Sep 2024 | Sep 2024 | USD 13.50 per 4090 at USD 9 (PANews) | Approximate Q1 2025 as the price reached USD 3.40 and difficulty followed the pools | "Difficulty plummeted ... as miners exited" (PANews); approximate over 50 percent of GPU provers within 90 days of the token-economics reveal |
+
+What the curve means per tier (the consequences rule), using the record's ratios rather than a price nobody can promise:
+
+| Tier | What the record says happens to them | What Igneum should tell them before launch |
+|---|---|---|
+| Home miner, one 8 or 12 GB card | First under power in every exit (the 3060 lost money on Clore's 2026 table while the 4090 still cleared) | Income per card at three prices, and that the glide never halves it overnight; the card keeps gaming when the income goes |
+| Home miner, one 16 to 32 GB card | Last GPU standing; still under power 6 to 18 months after a peak on every chain in the table | The proving pool is the second income for this tier only; say so, with the measured 15.6 GB profile |
+| Rig (6 to 12 cards) | Followed income across chains inside days (Hiveon: 16 percent to ETC, 7 percent to RVN) and shut down inside 90 days | Rig income at three prices; no loyalty expected, none needed, the 30-day weight pays staying miners a vote |
+| Pool user | Took the pool's choice of chain and the pool's fee; pools held 29 percent of Aleo proving at launch | Which pools carry the finality signer, and that a pool's vote is the user's weight (ledger G8) |
+
+The common shape, in numbers: income peaks inside one to six months of a price run or a migration, halves within 60 to 120 days as difficulty catches the price, and falls under power within six to eighteen months of the peak; when it does, 50 to 100 percent of the GPU hashrate leaves inside 90 days. The trigger was a chip twice (Kaspa, and ETC's second decline), a scheduled exit once (Ethereum), and the price three times (Ergo, Ravencoin, Aleo). In no case did a GPU lane recover its peak income after the exit.
+
+## 4. Verdict table
+
+| # | Lesson | Evidence (chain, year) | What Igneum does today | Gap | What the mission should add or change |
+|---|---|---|---|---|---|
+| 1 | A compute-bound hash goes to a chip in 16 to 37 months, and the first chip is private | Litecoin 2014, Zcash 2018, Nervos 2020, Kaspa 2023, Alephium 2024 | Random-program hash, 256 MB dataset, latency shadow, era draws; chip model 2.1x at class v4 (Horizon item 4) | Small | Decide the N ladder at genesis and publish the chip model with every era draw; nothing else |
+| 2 | Secret hardware or fleets show up as an unexplained hashrate step in the first weeks | Nervos 2020 (10x in 16 days), Iron Fish 2023, Kaspa 2023 | 90-day ramp from 10 percent; correlated-group detector and `security_alert` (Horizon rank 16) | Small | A public launch-week hash-origin report (key counts, pool shares, fleet shares) from the observer, daily for the first 90 days |
+| 3 | Hash forks by hand lose miners and add bugs; the client is the next failure | Monero 2018 to 2019 (85 percent gone per fork), Vertcoin 2018 to 2019, Ravencoin Aug 2026 (header flaw) | No scheduled human fork; era draws from chain state; 95 percent signalling with a floor; Devnet 2 gate | Large on the client | The second independent client is the item; until then a fuzz gate on header and PoW validation paths equal to the sync-request fuzz (Horizon rank 9) |
+| 4 | Income cliffs empty a chain in days; miners follow income with no loyalty | Ethereum Sep 2022 (94 percent of income gone), ETC -48 percent in four days, Aleo Q4 2024 | Monthly glide, no halving day, 1 percent tail (tail-emission.md) | Small on schedule, large on price | Publish per-tier income at three prices (USD 0.005, 0.02, 0.10) in the litepaper before the testnet, per the consequences rule; nothing in protocol |
+| 5 | Premine and insider allocation drive GPU miners out faster than any chip | Aleo 2024, Pyrin 2023 | No premine, no dev fund, no fee to any team | None | Nothing |
+| 6 | A GPU chain is rentable; rented hash reorganised three of them for USD 70 k to USD 18 M | Bitcoin Gold 2018 and 2020, Vertcoin 2018 and 2019, Musicoin 2019 | Miner-only finality on 30 days of blocks; 20 days of 100 percent hash to reach 2/3 (CLAUDE.md) | Small after day 20, large before | Weight-gated deep fork choice (Horizon rank 4) covers the first 20 days; ship it before mainnet, not after |
+| 7 | A coin with no market dies within a year whatever the hash does | Musicoin 2019, Akroma 2019, TurtleCoin 2023, Grin (USD 16 k daily volume), Nexa | Proving sold in dollars, settled in IGN (litepaper); Taiko named as first customer | Large until a customer pays | A signed proving customer before mainnet is a launch gate, with the same weight as the Devnet 2 gate; decouple the job price from `f_p` (Horizon rank 7) so the first job can clear |
+| 8 | Useful-work projects drop the miner the day the work does not pay | Dynex 2024, Flux 2025, Clore 2025, Qubic 2025 to 2026 | The lottery pays 80 percent of every block whatever the proving market does; proving is the second income, never the only one | None by design | Write the sentence into the litepaper: "A block pays its miner whether or not anyone buys a proof that day" |
+| 9 | Random-program hashes keep GPUs for five years and more, and still pay under a dollar a card | Ravencoin 2020 to 2026, Firo, Conflux, Iron Fish | The hash is Igneum's strongest answer | None on the hash | Stop presenting the hash as the reason to mine; present income, fairness and the second income (section 2's three wants) first |
+
+## 5. Headline findings for the coordinator
+
+1. Of the 31 rows (33 chains) that paid GPU miners since 2011, 8 lost the GPU lane to a chip, 7 closed it by their own choice (Dogecoin, Ethereum, Monero, Grin, Flux, Clore, Qubic), 10 died or went dormant on price, rental attacks or abandonment, and the 6 still GPU-only (Ravencoin, Ergo, Firo, Conflux, Iron Fish, Beam) pay USD 0.22 to 0.71 a day per RTX 3080 before power, so the hash keeps the miner and not the income.
+2. In 20 miner posts and launch texts read, 10 asked for hardware that keeps its value, 6 for income above electricity without a cliff and 4 for a fair supply; Igneum answers the fair supply in full, the hardware in part (a 2.1x chip model with the N ladder still owed), and the income only on schedule, since every GPU exit in the record except two came from price.
+3. The earnings curve has one shape across Ethereum, Kaspa, Ergo, Ravencoin and Aleo: income halves within 60 to 120 days of the peak, falls under USD 0.10 per kWh within 6 to 18 months, and 50 to 100 percent of GPU hashrate leaves inside 90 days of that, so the launch plan needs a signed proving customer and published per-tier income at three prices before the first miner buys a card.

+# Mission lane 5: what can be reinvented. The miner's experience
+
+Date: 7 October 2026, UK time. Lane 5 of the last mission. Written in the mission worktree; this file is the only output. Nothing was built, measured, posted or started; the live devnet was not touched.
+
+the project lead's words that this lane holds: "revolutionise the mining itself"; "dopamine for GPU miners everywhere, a structure that makes the mining commodity fall in love with the project"; "the perfect gpu network that will be noticed as the revolution that everyone is waiting for". Bounds that this lane obeys: no premine, no dev fund, no treasury, no token sale, no airdrop, no referral paid in coins; every coin is mined under the rules that exist (the 80/20 split, the signing bonus of 8 of the 80 producer points, the proving pool); no stake; no device bounty; the three signalling thresholds (60, 90, 95); miners are the security always; gates, not dates; hours are agent hours.
+
+## 0. Progress
+
+| Time (UK) | State |
+|---|---|
+| 08:46 | Rules read: CLAUDE.md, polish.md sections 1, 3.1, 3.2, 3.4, 3.6, 3.7, 3.10, 4.5; litepaper miner sections; vote-or-burn section 5; tail-emission one page; horizon one page; ledger decisions 3, standing, 6 and 7 October; pool.md; miner-ui-3 and its audit; testnet-go; the dev fee; the Discord kit; the Reddit kit (branch reddit-kit); journey.json |
+| 09:05 | Three research sub-lanes launched: Reddit post sample, chain histories, pool and install facts. The third refused by the concurrency limit; its topics done by hand with WebFetch. The session's WebSearch budget was already spent by other lanes, so every outside fact below comes from a fetched page or is labelled approximate |
+| 08:52 | Igneum maths computed (scratch `mission-reinvent/igneum-maths.txt`, `tiers.txt`): solo block expectations per tier at 100 GH/s and 1 TH/s, the vote dust line, the signing bonus per day |
+| 09:04 | Sections 3 to 8 drafted; 1.1 and 2 waiting on the sub-lanes |
+| 09:10 | Section 1.1 and headline 3 written from `reddit-sample.md` (105 posts, 69 with a room median) |
+| 09:13 | Section 2 and the sources written from `chains.md` (seven chains, hashrates derived from explorer APIs at dated heights) |
+| 09:15 | Done: 0 em dashes by grep, no placeholders, 446 lines; the three findings sent to the coordinator |
+
+## 1. The dopamine loop of a GPU miner, from data
+
+### 1.1 What the archives say
+
+Method (the sub-lane's file, scratch `mission-reinvent/reddit-sample.md`): 105 posts picked by hand from the top-of-all-time listings of r/EtherMining, r/gpumining, r/chia, r/ravencoin, r/MoneroMining, r/Monero, r/HeliumNetwork (2021 to 2022), r/kaspa and r/erg_miners (r/ErgoMining is an empty shell whose top post points to r/erg_miners), plus six bitcointalk "first block" posts from 2011 to 2017 through the ninjastic archive. Each post's score is the value Reddit served on 7 October 2026. The subreddit median for the post's year is estimated from three half-month samples of the Arctic Shift archive (approximate; the typical post in these rooms scores 1 to 4 points, so the ratios are large and describe how far the best joy posts rise above an ordinary post). 69 of the 105 rows have a ratio; r/MoneroMining and r/erg_miners have no archive sample.
+
+| Post type | Rows with a ratio | Median score | Median ratio to the room's typical post | Range | Best example (score, date, URL) |
+|---|---|---|---|---|---|
+| f. "My card paid for itself" (ROI, break-even) | 6 | 777 | 777x | 493x to 1,367x | solar panels paid for by mining, 1,367 points, 16 May 2021, https://www.reddit.com/r/gpumining/comments/ndduuu/ |
+| g. The community meme | 11 | 710 | 739x | 81x to 2,054x | "New miners be like...", 2,054 points, 19 Apr 2021, https://www.reddit.com/r/EtherMining/comments/mu3jgh/ |
+| c. The rig photo | 13 | 361 | 417x | 48x to 2,923x | "Rate my new build", 2,923 points, 3 Mar 2021, https://www.reddit.com/r/EtherMining/comments/lwpudz/ |
+| d. The hashrate milestone | 7 | 324 | 409x | 95x to 672x | "What 1GH looks like", 672 points, 8 Apr 2021, https://www.reddit.com/r/EtherMining/comments/mmybn2/ |
+| e. The profit screenshot, "X per day" | 7 | 234 | 234x | 48x to 593x | "I finally mined a full Ethereum today", 593 points, 21 Jul 2021, https://www.reddit.com/r/EtherMining/comments/ootl28/ |
+| a. First block found solo | 8 (plus 6 bitcointalk rows with no score) | 233 | 119x | 46x to 762x | "Tried Solo Mining ETH as an Experiment, Ended up Hitting a Block", 762 points, 3 Jun 2021, https://www.reddit.com/r/EtherMining/comments/nr13be/ |
+| h. "We did it", the network milestone (ATH, listing, hotspot count, halving) | 12 | 214 | 66x | 12x to 305x | Helium's first telecom deal, 305 points, 26 Oct 2021, https://www.reddit.com/r/HeliumNetwork/comments/qg9o6g/ |
+| b. First payout | 5 | 173 | 56x | 43x to 478x | "I made my first bitcoin penny", 478 points, 8 Mar 2021, https://www.reddit.com/r/gpumining/comments/m0emml/ |
+| all | 69 | 256 | 297x | 12x to 2,923x | |
+
+What the ranking says. The posts that rise highest are about the miner, not the network: the card that paid for itself (777x), the rig in a photo (417x), the personal hashrate milestone (409x). The network's own milestone, the thing a project would post, sits near the bottom (66x). The first solo block is the strongest single feeling in the quotes and a middling score (119x), because it is rare; the first payout is the lowest (56x), because on a pool it is routine. Chia's first-block posts are the exception that proves it: on a chain where the first win took weeks of plotting, "It finally happened! I never thought this day would come" scored 615 (19 May 2021, https://www.reddit.com/r/chia/comments/ngevxy/), 308x its room's median. The Monero room shows the same feeling at every size of CPU: "After 271 days and 101 Billion Hashes, I Finally Mined my First Monero" (128 points, 20 Nov 2020, https://www.reddit.com/r/MoneroMining/comments/jxxwzo/).

+
+Consequence for Igneum, by surface: the shareable thing must be the miner's own object (the block card with the card's name on it, the rig's row on the census, the weight rank), never the project's milestone; the ROI post cannot exist without a price, so its stand-in at the testnet is the line "N IGN per kWh" and the days-mined ring; and the solo first block must stay reachable for the common tier, which is the reason the Poisson line and the pool switch sit on the same screen (section 3.2).
+
+### 1.2 Time to the first hit on each chain
+
+| Chain, year | First hit | Measured or estimated time from install | Source |
+|---|---|---|---|
+| Ethereum 2017, pool (Ethermine, Nanopool) | first share accepted, worker on the dashboard | share within seconds of the first job; worker visible in 1 to 10 minutes; first payout at 0.05 ETH took one GTX 1070 about 2 to 3 weeks in mid 2017 (approximate) | approximate, from memory of the pool pages |
+| Ethereum 2017, solo | first block | a 30 MH/s card against 60 TH/s: one block in about 2 million blocks, 1 year or more; nobody did it (approximate) | approximate |
+| Kaspa, launch day 8 Nov 2021, solo | first block | the network was 3.4 MH/s on 8 Nov 2021 (derived from the header bits, `chains.md`), so one 2021 card found blocks within minutes; at 2.86 TH/s six months later the same card needed a pool | https://api.kaspa.org/blocks-from-bluescore?blueScore=100000 (7 Oct 2026) |
+| Kaspa 2022, pool (2miners) | first share; payout at 50 KAS every 2 hours | share in seconds; payout the same day for a 1 GH/s card in 2022 (approximate); 2miners: "Payouts are processed automatically every 2 hours", minimum 50 KAS | https://2miners.com/faq and https://kas.2miners.com/ (7 Oct 2026) |
+| Monero 2019, p2pool (from 2021) | a share in the PPLNS window, paid at the next pool block | p2pool: "It can take several days to a week to find a share if your hashrate is low"; min payout 0.00027 XMR | https://p2pool.io/ (7 Oct 2026) |
+| Chia 2021 | the first plot finished (the hit was the plot, not the coin) | 6 to 12 hours a plot on a consumer SSD; the expected solo win on 10 TB at 5 EiB netspace was months (approximate) | r/chia posts of May 2021 (section 1.1); approximate |
+| Helium 2021 | the hotspot on the map, the first beacon, "HNT per day" in the app | hours after power-on, days to weeks of waiting for the device itself (the r/HeliumNetwork top post of 2021 is a photo of a miner six months after ordering, section 1.1) | section 1.1 |
+| Ravencoin 2018, solo | first block, 5,000 RVN | on launch day any card found blocks in minutes (approximate) | approximate |
+| Igneum devnet, 2026 | first accepted block, shown in the app's event feed | an Apple silicon laptop through the DMG: first block "within the first minutes", 33 accepted blocks in 7 minutes; an RTX 5090 through the Windows installer: 34 accepted blocks in the first minute once the clock was right | `docs/bench-log.md` 4 October 2026 (the first outside machine; the three-card rig) |
+
+### 1.3 The loop
+
+| Stage | What it is for a miner | Evidence |
+|---|---|---|
+| Trigger | a number moved: a block, a payout, a hashrate tick, a chart on the explorer, a post in the feed | the post types that score highest are all "a number moved and here is the screenshot" (section 1.1) |
+| Action | open the app, the pool page, the explorer, the Discord; refresh | the daily ritual on every chain in section 2 |
+| Variable reward | blocks are a Poisson draw; the payout varies; the post's upvotes vary; luck is the word every pool shows | 2miners shows "luck 441%" and "last block 2 minutes ago" on the pool's front page (https://kas.2miners.com/, 7 Oct 2026) |
+| Investment | a rig built, plots made, a key aged, a reputation in the room, a name on a board | Chia's plots, Helium's named hotspot on the map, the EtherMining rig-photo post (section 1.1) |
+
+Igneum has one investment no other chain has: the vote key's 30-day window. A key that mined for 30 days weighs more than the same hashrate that appeared yesterday, and that weight signs finality. That is a level system written into consensus, and section 3.7 builds the ladder on it.
+
+### 1.4 The five moments on Igneum, and the time to each today
+
+Computed at 1 block a second, the producer share of 80 points, 100 IGN a block at full rate. The network size is the variable: the first 1,000 miners at the measured median card (about 25 MH/s, section 3.8) are about 25 GH/s; 100 GH/s is the litepaper's example; 1 TH/s is where the loop breaks for solo cards. Full tables per tier: section 3.8 and scratch `tiers.txt`.
+
+| Moment | Solo, 100 MH/s on 100 GH/s | Solo, 17 MH/s (8 GB) on 100 GH/s | Pool member, any card | Where it is shown today | Where it should be shown |
+|---|---|---|---|---|---|
+| 1. First share or first block | first block: expected gap 16.7 min, 97 percent within the first hour | 1.6 h expected, 46 percent within the first hour | first share: vardiff starts at one share per 10 s and the first correction is sized from the measured rate (`pool.md` section 2), so under a minute after the first job; before that the node sync and the dataset build (measured: the devnet laptop's first block "within the first minutes") | the event feed and the blocks strip (`app.js:1052-1127`) | the block card of section 3.3 |
+| 2. First payout | the coinbase of the first block, credited by the execution layer when the block is blue; so the payout is the block, seconds later | the same | PPLNS credit on blue confirmation; a payout round every 60 s (`pool/src/config.rs:61`), minimum 1 IGN; an 8 GB member at 100 GH/s earns 1 IGN in about 73 s, so the first payout lands inside two minutes of the first share | Earnings reads "£0.00 earned" and never shows mined IGN (Q18) | Earnings as section 3.4 |
+| 3. First proof shard paid | shards are assigned by lot to eight provers for ten seconds; 388 shards and 446.13 IGN paid on 5 October (the Discord kit's start-here text); on a 24 GB NVIDIA card today, 12 GB cards with the patched prover measured not shipped | not available on 8 GB today (core-only proving measured, `prover-tiers-real-cards.md` rows 4060) | proving income never passes through the pool (C6) | Prove tab state line "0 proven · 0 paid" | "your card proved shard N of block M" as a card, section 3.7 |
+| 4. First vote (the key above dust, 100 blocks in the 30-day window) | 1.2 days | 6.8 days | the member's own blocks carry its key (`pool.md` section 2, Votes), so the same days as solo for the same card; a member without a node has no vote (spec 09 9.7) | nothing: the app never says whether the key votes | "your key has a vote" card, the ladder rung 1 |
+| 5. First signature in a certified checkpoint, then the full window | the first checkpoint after the key enters the table (one checkpoint is 30 s; a young key counts as present); the full window at day 30 | the same; full window at day 30 | the same | nothing | "your signature is in checkpoint K" and "30 of 30 days" |
+
+The consequence of the dust line, per tier (the standing rule of 5 October): at 100 GH/s every tier reaches a vote inside a week; at 1 TH/s a single 8 GB card finds 44 blocks in 30 days and never reaches 100, so it never votes, and the pool does not help because weight follows the member's own found blocks. The 12 GB RTX 4070 reaches 65, also under. The RTX 5090 reaches 255. So past about 500 GH/s the "your key has a vote" rung is out of reach for the cards most of the first 1,000 miners own, and the X5 gate (1,000 independent keys above dust) gets harder as the network grows. This lane does not touch the constant; it hands the finality lane the question in section 8 and keeps the ladder's first rungs (first block, first payout, first shard, 30 days mined) reachable for every tier at any network size.
+
+## 2. The product structures that made miners fall in love
+
+Method (the sub-lane's file, scratch `mission-reinvent/chains.md`): hashrates derived from block difficulty at dated heights through each chain's public explorer API (Ergo, Monero, Ravencoin, Kaspa) or Etherscan's daily CSV (Ethereum); Helium and Chia from their own HIPs, blog posts and release notes; prices from CoinGecko. Every URL opened on 7 October 2026. "Approximate" marks a figure from memory. Hash units differ across forks and are not compared across them.
+
+### 2.1 The hook, the ritual, the proof, the ladder, the story
+
+| Chain | Hook | Daily ritual | Social-proof surface | Status ladder | The story a miner told |
+|---|---|---|---|---|---|
+| Helium 2019 to 2021 | a USD 500 box on the windowsill mines by giving radio coverage | the app or explorer.helium.com: the hotspot's 24-hour HNT, witnesses, "relayed" | the explorer hex map; every hotspot a dot with a three-word name; "the map was the product" | none formal: "first in my city" on the map, maker badges in Discord, validators from 2021 (approximate) | HIP 10's own example: a hotspot "which has earned approximately $21,000 worth of HNT by purchasing $145 worth of DC" (https://github.com/helium/HIP/blob/main/0010-usage-based-data-transfer-rewards.md) |
+| Chia 2021 | farm on drives you already own; "green Bitcoin" from the BitTorrent inventor | the GUI's netspace and "estimated time to win"; plots finishing; then the pool page | the netspace chart (chiaexplorer, xchscan); the pool leaderboard | plot count and TiB; "OG plots" against portable plots (approximate beyond that) | "It finally happened! I never thought this day would come" (section 1.1); the other side: "cries in 17TiB with 0 xch" |
+| Ethereum 2017 | the gaming PC prints money while you sleep | WhatToMine with your card list, the pool's unpaid balance and graph, the overclock | the pool's worker list and "estimated earnings"; YouTube rig builds; the GPU price chart | rig size (6, 8, 12 cards), hashrate, the "paid off" post (approximate) | "In Feb this subreddit told me it was too late and I'd never ROI" (893 points, 1 Aug 2021, https://www.reddit.com/r/EtherMining/comments/ovvaah/) |
+| Kaspa 2022 | "No premine. No hidden allocation. Fair launch." (https://kaspa.org/) | miningpoolstats.stream, the pool dashboard, Discord #mining | the miningpoolstats hashrate chart and pool count | Discord roles for early miners and pool operators (not verified, approximate) | "I mined six figures of KAS on two GPUs at a tenth of a cent" (approximate, the room's tone) |
+| Monero RandomX 2019 | any CPU, even a laptop, mines again; RandomX "optimized for CPUs" (https://www.getmonero.org/resources/moneropedia/randomx.html) | the xmrig console, the pool page, the electricity maths | the RandomX README benchmark table (i9-9900K 5,770 H/s, Ryzen 7 1700 4,100, i3-3220 510, Raspberry Pi 3 20; https://github.com/tevador/RandomX) and the pool's miner count | none formal; hashes per watt bragging | "After 271 days and 101 Billion Hashes, I Finally Mined my First Monero" (section 1.1) |
+| Ravencoin 2018 | Bitcoin's fair launch replayed for GPUs; "no private, public, founder, or developer allocation" (https://ravencoin.org/assets/documents/Ravencoin.pdf) | the pool dashboard, the WhatToMine line, Discord #mining, "is that hashrate jump an FPGA?" | the pool ranking and the explorer difficulty chart | none formal | "380 MH/s, about 24 hours total time mining. Very, very lucky." (section 1.1) |
+| Ergo 2019 | the ETH miners' second home: GPU-only Autolykos, a 2 GB table, "hardcoded no-premine proof" (https://github.com/ergoplatform/ergo/releases/tag/v3.0.0) | the pool dashboard, the explorer, WhatToMine, Discord #mining | the hashrate chart and the pool list | none formal | "My first payout. All mined with my humble GTX 1060 at 50MH/s." (section 1.1) |
+
+What the seven have in common: the daily ritual is a number read off a page the project does not control (a pool, miningpoolstats, WhatToMine); the social proof is a chart or a map; the ladder is informal everywhere. Helium is the one chain whose product was the proof surface itself (the map), and it is the one whose miners posted photos of the device six months after ordering (section 1.1). No chain had a ladder the chain itself computed.
+
+### 2.2 The numbers at 3, 6 and 12 months
+
+| Chain, launch | 3 months | 6 months | 12 months | Peak | Source |

+Discord member counts were not found in any source opened for any of the seven; the one community-size number in the sample is r/erg_miners passing 5,000 subscribers on 6 Jan 2022 (section 1.1, row 104).
+
+What the first year looked like from a card: Kaspa went from 3.4 MH/s on its first day to 2.86 TH/s at six months, a million-fold, and then 150x more in the next six (the post-Merge fleet); Chia's netspace rose about 300x in under four months, so a fixed farm's share fell 300x; Ethereum rose 26x across 2017. A miner who joined on day one of any of them watched their share fall by two or three orders of magnitude inside a year. Igneum's 30-day window gives that miner something the hashrate curve took away: weight that the newcomers cannot buy for 30 days.

+
+What Igneum takes from each: from Helium, a proof surface the miner owns (the map) and a warning that a company-run denylist with an unpublished method ends the love (section 6, "a number a company server has to be trusted for"); from Chia, that the ritual (plotting) must not destroy the hardware, and that a pool that arrives eight months late with the early miners shut out is remembered (pool-0 is at the go, section 3.5); from Ethereum, that the shareable post is the rig and the ROI, and that a chain can end mining by decree (Igneum's miners are the security always, so there is no Merge to decree); from Kaspa, that a fair launch holds a community for two years and an ASIC takes it in five months (the hourly program and the census, 4.4); from Monero, that "anyone's CPU" is a narrative that survives seven years when the hash keeps its promise; from Ravencoin, that two algorithm forks by human release are what Igneum's automatic schedule replaces; from Ergo, that a hashrate wave arriving from a dead chain dilutes the faithful 11x in two days, which is exactly what the 30-day weight window was built to keep from the vote.
+
+## 3. The miner's experience on Igneum, reinvented
+
+### 3.1 Install: the two warnings before the first screen
+
+What happens today (polish.md 3.10): Windows, SmartScreen "Windows protected your PC" (More info, Run anyway), per-user install, then a UAC prompt for the firewall rule 20 to 50 s in, on top of whatever screen is up. Mac, an ad hoc signature, Gatekeeper refuses, the user must find Privacy and Security, Open Anyway; the app strips its own quarantine on start. The Windows installer cannot be rebuilt tonight (Q80, GitHub billing).
+
+What the comparators do: SmartScreen warns on any file that is not "well known and downloaded frequently" and on any certificate without reputation; "If a URL, a file, an app, or a certificate has an established reputation, users don't see any warnings" (https://learn.microsoft.com/en-us/windows/security/operating-system-security/virus-and-threat-protection/microsoft-defender-smartscreen/, page dated 23 April 2026, read 7 Oct 2026). SSL.com's code-signing page says Microsoft "moved away from automatic instant reputation", so OV and EV build reputation through use (https://www.ssl.com/code-signing/, 7 Oct 2026). Apple: USD 99 a year, notarisation included (https://developer.apple.com/programs/, 7 Oct 2026); on macOS the unidentified-developer path is System Settings, Privacy and Security, Open Anyway (https://support.apple.com/en-us/102445, 7 Oct 2026). Certum sells an open-source code-signing certificate "from €49.00" (https://shop.certum.eu/open-source-code-signing-on-simplysign.html, 7 Oct 2026; out of stock on the day). Azure Trusted Signing: Basic tier 5,000 signatures a month, one certificate profile of each type; price not shown on the page (https://azure.microsoft.com/en-us/pricing/details/trusted-signing/, 7 Oct 2026; from memory about USD 10 a month, approximate). GPU miners trip antivirus even when signed: T-Rex's README says some engines detect signatures "similar to those that real viruses protected by the same packer have" (https://github.com/trexminer/T-Rex, 7 Oct 2026).
+
+| Step | Today | Proposal | Hours | Gate |
+|---|---|---|---|---|
+| Mac signature | ad hoc, quarantine strip | Developer ID plus notarisation and stapling in `build-dmg.sh`; the quarantine strip removed | 3 plus the project lead's USD 99 | a fresh macOS 26 machine opens the DMG's app with no Privacy and Security visit |
+| Windows signature | none | Authenticode through Trusted Signing or an OV certificate, signed on the box as a job step; the sha256 and the signer's name on the download page (Q50, Q82) | 3 plus the project lead's purchase | a fresh Windows 11 machine runs the installer with no SmartScreen interstitial by the 1,000-download mark (reputation is use; before that the page shows the exact interstitial text and the two clicks) |
+| Firewall prompt | UAC 20 to 50 s in, unexplained | the Cards screen names it and the step runs after `setup_done` (Q14) | 1 | the prompt never appears before a screen that says it will |
+| Antivirus | nothing | a "What your antivirus may say" line on `/miner#get` with the engine names and the exact action, and the submission to Microsoft's SmartScreen review on every release (the Learn page's submission route) | 1 | the line is on the page; every release's binaries are submitted the day they ship |
+| Time to the first share | not measured end to end on a fresh machine | measured on a fresh Windows 11 VM and a fresh Mac for every release by the Devnet 2 gate: download to first accepted share or block, with the clock, the sync and the dataset build as three timed steps | 2 | "first share within 10 minutes of download in 9 of 10 fresh Windows installs", published on `/evidence` |
+
+### 3.2 First run: what the first hour should feel like
+
+Today's three screens (Welcome, Cards, Address, the key sheet) are rated 7 to 8 of 10 by the UI 3 audit; the audit's own finding is that the one question a home miner has, "is this worth running", is not answered until the third screen, and the Cards row does not say what the card is expected to make although `site/miner-priors.json` knows the model (`miner-ui-3-audit.md` 2.1, 2.2).
+
+| Screen | Add | Hours | Gate |
+|---|---|---|---|
+| Cards | under each known model: "about 25 MH/s at 91 W; on today's network that is about N blocks a day" from the prior and the live network rate | 1 | the row shows a number for every model in the priors file |
+| Cards | the tier sentence in plain words: "8 GB: mines; proves small shards", "24 GB: mines and proves" (from `prover-tiers-real-cards.md`) | 0.5 | every memory size has a sentence |
+| Address | "Start mining" starts mining; the key sheet comes before the button (the audit: "the button lies once") | 1 | view test |
+| Mine, first ten minutes | a "waiting for your first block" line with the live expectation: "a card like yours finds a block about every 1.6 hours on today's network; chance so far: 31 percent" (a Poisson line from the card's own rate and `/api/stats` network rate; the pool mode shows "first share in N s" instead) | 2 | the line is on screen from the first job until the first block, then is replaced by the block card |
+
+The Poisson line is the piece no miner app has. 2miners shows luck for the pool; nothing shows a solo miner's own running chance. It turns the dead first hour into a count-up, and it is honest: it says 46 percent for an 8 GB card at 100 GH/s, which is why the pool switch sits one line below it.
+
+### 3.3 The first block: the card, the sound, the link
+
+Today: an event line in the feed and the blocks strip. Nothing is shareable, nothing is kept.
+
+Proposal, the block card (Ember, Mine page, in place, no dialog):
+
+```
+Block 1,284,117 is yours.                                 12:27:53 UK
+RTX 4070 · 25.0 MH/s · 0.025% of the network
+80.00 IGN to 0xdd44…86E8 (72 producer points, 8 for signing)
+Hash 9f3a…c21e   [Open in the explorer]   [Save the card]   [Copy the link]
+```
+
+| Element | Rule | Hours | Gate |
+|---|---|---|---|
+| The card | shown on the first block of every key, then on every 100th, 1,000th and 10,000th, and on the first block of every new card; stays until dismissed; the rest are feed lines | 2 | view test on the four thresholds |
+| Sound | off by default; one short tone on a block when on; honours reduced motion and the OS mute (`app.css` already honours reduced motion everywhere) | 0.5 | the tone never plays when the switch is off |
+| Save the card | a 1200x630 PNG drawn locally from the same data (the rig-photo post without the rig; the dark scheme, the brand mark, the card name, the hash, the explorer link as a QR) | 2 | the PNG opens; no network call is made to make it |
+| The link | `/block/<hash>` (exists: parents, children, mergeset, shards, checkpoint fractions, `block.html:285-325`) | 0 | |
+| What is not on it | no fiat, no price, no "worth": there is no market and the copy law forbids the aphorism | | |
+
+The pool user gets the same card for the first share ("Share accepted by pool-0 · 0.0012 of a block") and the first credited block ("pool-0 found block N; your share 0.41 IGN"), from the `share_result` and the PPLNS credit lines the pool already sends.
+
+### 3.4 The app: Earnings
+
+Today (`miner-ui-3.md` section 5, polish Q18): the first number on the tab is "£0.00 earned: nothing is bought or sold on devnet"; mined IGN is never shown, only proving `paid_wei`; the electricity line is real and shown as a cost.
+
+| Line | Today | Should read | Source of the number | Hours |
+|---|---|---|---|---|
+| 1 | £0.00 earned | **6,912 IGN a day** at your last hour's rate (86 blocks) | the node's own block count for the key times the subsidy at the block's DAA; the projection from the 1-h rate and `/api/stats` network rate | 2 |
+| 2 | 0.0000 IGN from 0 proofs | 2,592 blocks in 30 days, 207,360 IGN; 14 shards, 16.1 IGN | the node and the execution layer (the balance is in the wallet; the app reads the coinbase credits per key) | 1 |
+| 3 | none | about £N a day at a price you type (no exchange lists IGN; a typed price, remembered, never fetched) | the user's field; the engine's `price_gbp_per_ign` when a market exists, as the UI 3 plan already owes | 1 |
+| 4 | none | your card is 0.100 percent of the network; weight rank 41 of 1,204 keys; 30 of 30 days | `/api/live` miners and the finality weights RPC (`getFinalityWeights`, spec 3.10) | 2 |
+| 5 | £1.95 a day electricity | unchanged, and the line under it: "N IGN per kWh" | the existing watt reading | 0.5 |
+| 6 | dev fee line | unchanged (1 in 100, the switch) | | 0 |
+
+A rule for every number on the tab: it comes from the node this machine runs, or from the public API with the field named on hover (polish 4.3, one formatter table). The typed price is the only number the user supplies and the tab says so.
+
+### 3.5 The pool
+
+Decision for the launch pool, with reasons:
+
+| Question | Decision | Why |
+|---|---|---|
+| Who runs it | the project runs pool-0 at the testnet go and at mainnet genesis, on the written systemd unit (`pool/README.md`), with the member's vote key in every header as built | nobody else can on day 1; the member-key design means the project's pool never holds vote weight, which is the thing a project pool is normally criticised for |
+| Fee | 1 percent, the same as the solo dev fee, published in `welcome`, on the page and on `/miner` | a 0 percent project pool makes every outside pool unviable, and the first outside pool is a launch gate (section 4.1); 1 percent is what miners accept everywhere (2miners 1.0 percent, https://kas.2miners.com/, 7 Oct 2026; Ethermine 1 percent, approximate); fee-neutral between solo (dev fee 1 in 100) and pool, so the choice is about variance only |
+| Where the fee goes | the same software address as the dev fee; it is a software fee, documented as such (`miner-dev-fee.md`), never a protocol fee | no dev fund, no treasury; the protocol carries no fee to anyone |
+| Mode | PPLNS, window 2 blocks of weight, payout rounds every 60 s, minimum 1 IGN (as built) | the first payout inside two minutes of the first share for an 8 GB card at 100 GH/s (section 1.4) |
+| Default in the app | solo under 500 GH/s network, the app suggests the pool above it, per card: "a card like yours finds a block about every 16 hours on today's network; pool-0 pays every minute" | the Poisson line of 3.2 decides; the user chooses |
+| What the pool page shows | the connect card, the lookup, the blocks and the payments table (Q71 owed), luck in MiningPoolStats' convention (Q69, Q72), "payouts follow blue confirmation, not finality" (Q73), and the finality state | the comparator rows in polish 3.6 |
+| TLS | before the public testnet (Q67, 8 hours, consensus-engineer) | spec 9.3 |
+
+The variance arithmetic that makes the pool required, computed: a single 8 GB card at 17 MH/s finds a solo block every 1.6 hours at 100 GH/s, every 16 hours at 1 TH/s (23 percent of days with no block), every 6.8 days at 10 TH/s (36 percent of weeks with no block), every 68 days at 100 TH/s. The pool is optional at launch size and required from about 1 TH/s. The pool's own payout latency: credit on blue confirmation (seconds), a round every 60 s, so under two minutes end to end once the member's balance passes 1 IGN.
+
+### 3.6 Community: the Discord, the live page, the leaderboard, the miners page, the explorer
+
+What exists: the Discord kit (roles Founder, Core, Prover, Miner, Bot; channels INFO, CHAIN, LEDGER, TALK; the bot posts a pulse four times a day, a daily digest, weekly numbers, releases, incidents; nothing live yet, Q7); `/live` with a Miners lane list of vote keys with a block in the last 10 minutes; `/miners` the bench table (six rows, Q51); the explorer with Miner as the payout address per block; `/address` (noindex) with balance and blocks mined.
+
+| Surface | Add | Rule that keeps it honest | Hours | Gate |
+|---|---|---|---|---|
+| Discord #first-blocks | the bot posts every first block of a new key (short key id, the block link, the card model if the miner opted in through the app's "show my card" switch) | from the public API only; the forbidden-string guard; no name, no machine id | 2 | ten first blocks posted on Devnet 2 with the right links |
+| Discord roles | Voter (the key is above dust, verified by a message signed with the vote key against `getFinalityWeights`), Window (30 of 30 days), Prover (as built) | chain-side facts, anyone can check the same RPC | 3 | a role granted and revoked by the chain's numbers in a test |
+| `/live` Miners | a leaderboard by 30-day weight: rank, short key id, blocks in window, days mined, signing presence, last block; a toggle to the 10-minute view that exists | weight, never hashrate; a renter who arrived today is at the bottom whatever they rent | 3 | the page shows the top 100 by weight with days-mined; a key that stops mining falls one place a day |
+| `/address/<key or address>` | the public profile: blocks in 30 days, weight rank, vote state, checkpoints signed, shards proven, first block date, the block cards | noindex stays until the owner opts in from the app ("make my page public") | 3 | the page renders for every key in the window |
+| `/miners` | the hardware census (section 4.4): one row per card model from the hourly program's per-card timings, MH/s, W, MH/W, count of keys on that model, median first-block time | measured, scrubbed, no machine names (the bench-table rule) | 4 | eleven rows today, every model with three or more keys after the testnet go |
+| Explorer block page | "found by key id N, rank 41, day 23 of 30" under Miner | from the same weights | 1 | the line on every block |
+
+### 3.7 Why I stay: the ladder written into consensus
+
+The thing no other chain has: vote weight is 30 days of blocks per key (rule v2). A level system with no points server, no badge contract and no company database: the chain computes it, the node reports it (`getFinalityWeights`), the wallet verifies the certificates it signs.
+
+| Rung | Name on screen | Rule | Time for a 100 MH/s card at 100 GH/s | Time for an 8 GB card at 100 GH/s | Where shown |
+|---|---|---|---|---|---|
+| 0 | First block | one blue block with your key | 16.7 min expected | 1.6 h | the block card; #first-blocks |
+| 1 | Your key has a vote | 100 blocks in the window (the dust line) | 1.2 days | 6.8 days | Mine hero, address page, Discord Voter |
+| 2 | Your signature is in checkpoint K | the first certified checkpoint carrying the key's vote | the next 30-s checkpoint after rung 1 | the same | the finality line in Mine, the block page of the lock |
+| 3 | Full window | 30 of 30 days with blocks | day 30 | day 30 | the days ring in the hero; Discord Window |
+| 4 | Rank | position by weight among all keys | continuous | continuous | `/live` leaderboard, Earnings line 4 |
+| 5 | Signing streak | days since the key last missed the presence window (the 8 points never lost) | continuous | continuous | Earnings: "signing 8 of 80 points, 41 days unbroken" |
+| P | Your card proved shard N of block M | a paid shard record | hours on a 24 GB card; not yet on 8 GB | not yet | the Prove tab card, Discord Prover |
+
+The exact lines, in copy law: "Your key has a vote." "Your signature is in checkpoint 184,220." "Your card proved shard 3 of block 1,284,117." "30 of 30 days. Full weight." "Rank 41 of 1,204 keys." Each line names the chain fact behind it on hover (the RPC field), the same rule as every number on the site.
+
+What the rungs pay, so the ladder is not decoration: rung 1 is the vote itself; rung 2 starts the 8-point signing line (the public sentence: miss two hours of signing and the next blocks pay 72 until you sign again); rung 3 is maximum weight; rung P is the proving income (20 points of every block, split by shard). Nothing is paid from a fund; the ladder only names what the rules already pay.
+
+### 3.8 Per tier: the first hour and the first month
+
+Cards at the measured untuned rates of `docs/analysis/prover-tiers-real-cards.md` (rented, 6 October 2026) and the bench table; expectations at 1 block a second; the first month at full rate (100 IGN a block) and at the 90-day ramp approved for the testnet genesis on 7 October (10 percent on day 1, so divide the IGN column by 10 on launch day; CLAUDE.md's 30-day ramp is the earlier text).
+
+Network 100 GH/s:
+
+| Tier | Gap to a solo block | Block in the first hour | Blocks a day | IGN a day (80 points) | Days to a vote | First month: blocks, and what the key is |
+|---|---|---|---|---|---|---|
+| 8 GB, RTX 4060 (17.07 MH/s) | 1.6 h | 46 percent | 14.7 | 1,180 | 6.8 | 442 blocks; a voter from day 7; full window day 30; proves core-only shards (`prover-tiers` row 4060) |
+| 8 GB, RX 9070 XT (17.9) | 1.6 h | 48 percent | 15.5 | 1,237 | 6.5 | 464; a voter from day 7; no proving (CUDA only today) |
+| 12 GB, RTX 4070 (24.99) | 1.1 h | 59 percent | 21.6 | 1,727 | 4.6 | 648; a voter from day 5; mines and proves on the patched prover when shipped |
+| 12 GB, RTX 5070 (41.89) | 40 min | 78 percent | 36.2 | 2,895 | 2.8 | 1,086; a voter from day 3 |
+| 16 GB, RTX 4060 Ti (17.58) | 1.6 h | 47 percent | 15.2 | 1,215 | 6.6 | 456; a voter from day 7; mines and proves |
+| 24 GB, RTX 4090 (52.25) | 32 min | 85 percent | 45.1 | 3,612 | 2.2 | 1,354; a voter from day 3; mines and proves today |
+| 32 GB, RTX 5090 (98.48 rented; 122 on PC 1) | 17 min | 97 percent | 85.1 | 6,807 | 1.2 | 2,553; a voter from day 2; proves beside the miner |
+| Apple M5 Max, Metal (26.7) | 1.0 h | 62 percent | 23.1 | 1,846 | 4.3 | 692; a voter from day 5; proves on the CPU, slowly |
+| Rig, 6 x RTX 4090 (313.5) | 5.3 min | 100 percent | 271 | 21,669 | 0.4 | 8,126 (one key per machine, the 6 October default) |
+| Pool member, any of the above | first share under a minute; first credit under two minutes | 100 percent | the same blocks on average, paid every minute | the same minus 1 percent | the same days (weight follows the member's own blocks) | the same |
+
+Network 1 TH/s (the same cards):
+
+| Tier | Gap to a solo block | Block in the first hour | Blocks a day | IGN a day | Days to a vote | 30-day blocks |
+|---|---|---|---|---|---|---|
+| 8 GB, 17.07 MH/s | 16.3 h | 6 percent | 1.5 | 118 | 68 (never inside the window) | 44 |
+| 12 GB, 24.99 | 11.1 h | 9 percent | 2.2 | 173 | 46 (never) | 65 |

+
+Per OS and vendor, what differs in the first hour: Windows, two prompts (section 3.1) and NVIDIA through the driver, AMD and Intel through OpenCL; macOS, one prompt, Apple silicon through Metal, no watt reading so no pounds line; Linux and HiveOS, no prompt, the Flight Sheet fields, Hive itself untested on a real rig (`/miner`). AMD cannot prove today (CUDA only). The 12 GB tier cannot mine and prove at once on the shipped build (peak 15.6 GB measured, bench log 5 October); the patched prover's 10.1 GB peak beside the miner on the 4070 is measured and not shipped.
+
+### 3.9 The first withdrawal, and the first "I own something"
+
+No exchange at the testnet, none arranged or sought at mainnet (journey phase 6). So the first ownership moment is not a withdrawal. It is:
+
+| Moment | Today | Proposal | Hours |
+|---|---|---|---|
+| The balance | in the wallet ("the balance is in the wallet", Earnings); the address page shows balance and blocks | the Earnings tab shows the balance read from this machine's node, with "verified by this node" on hover | 1 |
+| The proof | the wallet verifies finality certificates with the node's own code (`finality.rs:101-121`) | the first block card carries "final under checkpoint K, certificate verified by this machine" once the lock lands, and the address page shows the latest locked checkpoint (Q37) | 1 |
+| The QR | the wallet draws the `ethereum:` URI locally (`server.rs:140`) | the saved block card carries the explorer link as a QR; the address page's QR under "make my page public" | 0.5 |
+| The send | EIP-1559 value transfers in the wallet | a first-transfer card in the wallet: "sent 10 IGN to 0x…, in block N, final under checkpoint K" with the state words pending, included, executed, proven, finalised (UI 3) | 0 beyond Q9 |
+
+"I own something" on Igneum is "a block with my key is final under a certificate my own machine verified". No other chain's miner app says that sentence.
+
+## 4. The exact structure for Igneum
+
+### 4.1 The launch sequence as gates
+
+The go checklist (`docs/plans/testnet-go.md`) has eleven steps, from the seeds at height 0 to the first miner's block 1. These are the community gates that follow it; none has a date.
+
+| Gate | Definition | How it is measured | What opens when it passes |
+|---|---|---|---|
+| G-C1 First 100 keys | 100 distinct vote keys with a block in the last 24 h | `/api/live` miners over a day | the #first-blocks channel goes live; the leaderboard shows ranks |
+| G-C2 First block by a card the project does not own | a block whose key is not in the project's fleet list | the observer's key list against the fleet file (the Discord guard already reads it) | the "first outside block" post, with the owner's permission |
+| G-C3 First outside-reproduced benchmark | a card row on `/miners` measured by someone outside the project, with driver, OS and version (Discord rule 6) | the bench-table ingest with `by: reported by a miner` | the census starts (4.4) |
+| G-C4 First pool not run by the project | a pool at an address the project does not control with 10 percent of blocks for 7 days, the member key in its headers | the explorer's payout-address share | pool-0 stays at 1 percent; the app's pool list gains a second entry |
+| G-C5 First 1,000 independent keys | X5 as decided on 6 October: 1,000 keys above dust over 30 days, independent in autonomous system, machine fingerprint and pool attestation, top-10 share of window weight under 50 percent; a silent key counts only if its AS is its own | the observer's AS and fingerprint columns (owed, one app-owner item) | journey phase 5 closes; mainnet genesis is the next gate |
+| G-C6 First outside proving customer | one rollup's job proven and paid on its own chain | the job market's payout contract | phase 4's second half |
+
+### 4.2 The first 1,000 miners: where they come from
+
+The no-airdrop constraint shapes every row: nothing is offered for joining; the only pay is mined emission; the message is the number and the file. Costs are agent hours for the content and the answering; the expected counts are this lane's estimates and labelled so.
+
+| Channel | Expected keys (approximate) | Hours | The message | Rule |
+|---|---|---|---|---|
+| r/gpumining (the Reddit kit's day-7 post: eleven cards, MH/s, W, MH/W) | 150 to 300 | 6 (post, 48 h of answers) | the card table; "devnet coins have no value; nothing is for sale"; the ledger | rule 2.10 (no referral or promo links); the founder reads the Expanded Rules first |
+| r/EtherMining (the Merge story, under rule 7's disclosure) | 100 to 200 | 4 | four years after the Merge, what runs and the command to check it | one linked post per seven days; nobody sent to Discord |
+| HiveOS forum and the custom-miner listing | 100 to 250 (rigs, so more hashrate than keys) | 4 plus the first real Hive run | the HiveOS card verbatim, "Hive itself is untested so far; report what breaks" | the first reported rig run gets a bench row and the Miner flair |
+| Bitcointalk ANN | 50 to 150 | 3 plus daily answers for a week | the ANN format: no premine, no sale, the dev fee, the card table | no bounty, no signature campaign |
+| Miner Discords (lolMiner, BzMiner, Hive, the Kaspa and Ergo mining rooms) | 100 to 200 | 3 | two sentences, the card table, the ledger, "nothing is for sale" | one message per server in its projects channel |
+| The miner-software authors (lolMiner, BzMiner, Team Red, Rigel) | 0 to 300 keys on the day one of them ships Igneum | 8 (the worker protocol document, the vectors, the dev-fee template mechanism explained so their fee works in solo mode) | "a fee template is 1 in 100 by a counter; your fee rides the same mechanism" | their fee is theirs; the protocol carries none |
+| r/CryptoTechnology, r/zkproofs, r/Monero (the design rooms) | 30 to 80 | 4 | the prover, the verify command, the vs RandomX table | comments only where the rules say so |
+| The hardware census itself (4.4), once G-C3 passes | 100 to 300 over the first months (people come to get their card measured on a public board) | 0 beyond the board | "your card's row, measured by the chain, not by us" | scrubbed, no machine names |
+| Total | 630 to 1,780 keys, median about 1,000 | 32 | | |
+
+Every row is the Reddit kit's existing text or an extension of it; the only new content is the census board and the worker-protocol document for the miner authors.
+
+### 4.3 The pool at launch
+
+Decided in 3.5: project-run pool-0 at 1 percent, member keys in headers, PPLNS, 60-s rounds, the dev fee off in pool mode because the pool fee is the same 1 percent to the same software address. The outside pool is a gate (G-C4), not a hope: the pool crate is public with its README, and the app's pool field takes any host.
+
+### 4.4 The leaderboard and the census
+
+| Board | Ranks | Never ranks | Source | Why |
+|---|---|---|---|---|
+| Keys (`/live`, the address page, Earnings line 4) | 30-day weight (blue blocks per key in the window), with days mined and signing presence | hashrate | `getFinalityWeights` | a renter who arrives today has no weight; a laptop that mined for 30 days outranks a rented rig's first week; the board is the chain's own security table, so it cannot lie without the chain lying |
+| Cards (`/miners`, the census) | efficiency per card model: MH/s, W, MH/W, and the per-program timing spread from the hourly swap (the frontier lane's "8,760-question hardware census", `frontier.md` 4.3) | people | the hourly program's per-card timings, the bench-table ingest, scrubbed | the public benchmark the litepaper promises, made continuous; a chip that does better than the GPU curve shows up on this board first |
+
+The census is new: RandomX programs are per hash and no pool sees their timing; Igneum's hourly program with per-card racing produces the census as a by-product (`frontier.md` 4.3). It is the one leaderboard a miner wants that no chain has, and it doubles as the chip alarm.
+
+### 4.5 The story each miner tells
+
+Written in copy law (short sentences, no antithesis, no aphorism).
+
+| When | The three sentences |
+|---|---|
+| First week | "I installed it in five minutes and the first block was mine inside the hour. Every block pays my address straight away. My 4070 is on a public board with its watts." |
+| First month | "My key has a vote now. It signs finality every 30 seconds and I can see the checkpoint it is in. After 30 days my weight is full, and the rented farms that showed up last week sit under me." |
+| First year | "The program has changed 8,760 times and my card still mines it. My card has proved 400 shards for a rollup I have never heard of. Nothing was sold and nothing was given away: every coin I hold was mined." |
+
+## 5. The surfaces to change
+
+| Surface | Today (polish.md) | Should show | Hours | Gate |
+|---|---|---|---|---|
+| Ember, Cards | card name, switch, "worker Metal, 40 GPU cores" (audit 2.2) | expected MH/s and W from the priors, "about N blocks a day on today's network", the proving tier sentence | 1.5 | every model in the priors shows a number |
+| Ember, Mine (before the first block) | the blocks strip, 10 minutes (`app.js:1052-1127`) | the Poisson count-up line; the pool suggestion when the gap passes 8 h | 2 | the line shows from the first job to the first block |
+| Ember, Mine (the block card) | an event line | the block card of 3.3, saved PNG, the explorer link | 4.5 | the four thresholds; the PNG with no network call |
+| Ember, Earnings | "£0.00 earned", mined IGN never shown (Q18) | IGN a day, blocks and IGN in 30 days, shards and IGN, a typed price, share of network, weight rank, days, signing streak | 6.5 | every line names its RPC field on hover; a view test per line |
+| Ember, Prove | state line "0 assigned · 0 proven · 0 paid" | the shard card "your card proved shard N of block M, 1.15 IGN" | 1 | a card on the first paid record on Devnet 2 |
+| Ember, Settings | pool field designed, not built (`pool.md` section 7) | the pool field, the terms box from `welcome`, the dev-fee line reading "off in pool mode: the pool's 1 percent is the same fee" | 3 | a member connects from the app and shows the terms |
+| Ember, first run | two prompts, one unexplained (Q3, Q14) | signed and notarised; the firewall step named on the Cards screen | 7 plus the project lead's certificates | 3.1 gates |
+| Wallet | one account, no finality state on the address page (Q33, Q37) | the first-transfer card with the five state words; the address page with the latest lock | 3 (plus Q9's 6) | a devnet transfer walks the five words on screen |
+| Site `/miner` | "Install. Start. The card mines and proves." plus feature lines | the first-hour timeline (download, the one prompt, first share, first block, first payout) with the measured times from the Devnet 2 gate | 2 | the times on the page equal the gate's log |
+| Site `/live` | miners with a block in 10 minutes | the weight leaderboard with days mined and signing presence; the 10-minute view as a toggle | 3 | top 100 by weight; a stopped key falls one place a day |
+| Site `/miners` | six rows, two models, "not measured" MH/W (Q51) | the census: one row per model, MH/s, W, MH/W, keys on that model, median first-block time | 4 | every model with three or more keys |
+| Site `/address` | balance, blocks, noindex | the public profile of 3.6 behind the app's opt-in | 3 | renders for every key in the window |
+| Explorer block page | Miner = payout address | "found by key id N, rank 41, day 23 of 30" | 1 | on every block |
+| Pool page | stat strip, connect, lookup, blocks, no payments table (Q71) | payments, luck in the standard convention, "payouts follow blue confirmation, not finality", finality state | 3 | the comparator rows in polish 3.6 |
+| Discord | nothing live (Q7); roles Miner and Prover by hand | the bot live; #first-blocks; Voter and Window roles from chain facts | 8 | ten first blocks on Devnet 2 posted; a role granted by a signed message |
+| Total | | | 52.5 plus the certificates | |
+
+## 6. What not to build
+
+| Idea | The line that kills it |
+|---|---|
+| Gamification paid from a fund (a weekly prize, a "block of the day" bonus) | there is no fund; every coin is mined under the 80/20 rule and the signing bonus, and a prize paid by the project is a premine by another name |
+| Referral in coins | no referral paid in coins from a fund: there is no fund; and r/gpumining rule 2.10 bans referral codes outright |
+| An airdrop for installing, posting or reproducing a benchmark | an airdrop in exchange for anything is a sale by another name; the rule is "nothing is for sale" on every surface |
+| NFT badges for the rungs | the rung is a chain fact already (weight, days, signatures); a token for it adds a contract, a market and a price to a thing that must stay a number |
+| An off-chain points system | a number a company server has to be trusted for; the ladder's rule is that every number is a chain fact anyone can read from an RPC |
+| A rank-by-hashrate board | a renter tops it on the first day; the only board is weight, which takes 30 days |
+| A "top earners" board in fiat | there is no price; a typed price is the user's and stays on their machine |
+| A Discord level bot (MEE6-style XP for messages) | a number a server owner sets; it rewards talking, not mining |
+| A bounty for the first ASIC, or a device bounty | ruled out (M1, M22); a device bounty is a sale of the chip |
+| Streaks that penalise a miss (lost rungs, demotion) | the signing bonus already prices a miss (72 until you sign again) and nothing is burned; a second penalty on top is the burn the owner refused |
+| Any surface whose number needs a company server to be trusted | the observer, the API and the Discord bot are conveniences; every number they show must be reproducible from a node, or it is not shown |
+
+## 7. Verdict table
+
+| Proposal | Evidence (chain, year, number) | Newness | Hours | Gate | Recommend |
+|---|---|---|---|---|---|
+| Signed and notarised installers | SmartScreen warns on any file without reputation (Microsoft Learn, 2026); polish Q3 | everyone has it; we lack it | 7 plus certificates | no interstitial on a fresh Mac; the Windows one gone by 1,000 downloads | do now |
+| The Poisson count-up before the first block | 2miners shows pool luck (kas.2miners.com, 2026); no app shows a solo miner's own running chance | nobody has it | 2 | the line shows until the first block | do now |
+| The block card with a saved PNG | EtherMining's rig photo 2,528 points in 2021 (section 1.1); the Helium miner photo 860 in 2021 | nobody has it in a miner app (approximate) | 4.5 | PNG with no network call | do now |
+| Earnings in IGN first, a typed price second | NiceHash shows fiat first (polish 3.1, approximate); Q18 | someone has fiat; nobody has "typed price, never fetched" | 6.5 | every line names its field | do now |
+| The weight ladder: vote, signature, full window, rank, streak | rule v2 (Igneum, 2026): weight is 30 days of blocks per key | nobody has it | 6 (across Ember, address page, Discord) | a Devnet 2 key walks every rung on screen | do now |
+| The weight leaderboard on `/live` | Kaspa pools rank workers by hashrate (approximate); Helium ranked hotspots by HNT (section 2) | nobody ranks by consensus weight | 3 | top 100 by weight | do now |
+| The hardware census on `/miners` | frontier 4.3; the litepaper's promised benchmark | nobody has it | 4 | every model with three keys | do now |
+| Pool-0 at 1 percent, member keys | 2miners 1.0 percent fee (2026); spec 09 member votes | the member-key pool is new; the fee is standard | 0 beyond Q67 to Q73 (about 20) | G-C4 | do now |
+| #first-blocks and the Voter and Window roles | Discord kit roles (2026); chain-side facts | nobody grants a role from consensus weight (approximate) | 5 | roles from a signed message | do now |
+| The public address profile behind an opt-in | Helium's explorer hotspot page (2021), section 2 | someone has it (Helium); ours adds the vote and the signatures | 3 | renders for every key | prototype |
+| The first-hour timeline on `/miner` with measured times | the devnet laptop's 7 minutes and the 5090's first minute (bench log, 4 Oct 2026) | ethereum.org and kaspa.org have no measured install time (approximate) | 2 | the page equals the gate's log | prototype |
+| The worker-protocol document for miner authors | lolMiner 0.75 percent Kaspa fee, T-Rex 1 percent (their READMEs, 2026) | standard | 8 | one outside miner ships Igneum | prototype |
+| A dust line that scales with the network | section 1.4: an 8 GB card never votes past about 500 GH/s | a finality-lane question | 0 here | the finality lane's answer | watch |
+| Sound on a block | every pool page has a block sound option (approximate) | standard | 0.5 | off by default | watch |
+| Anything in section 6 | | | | | never |
+
+## 8. Three headline findings for the coordinator
+
+1. At the litepaper's 100 GH/s network a solo 8 GB card finds its first block in 1.6 hours expected and 46 percent of them see no block in the first hour, so the first-hour dopamine for the most common tier is the Poisson count-up line and the pool's first share under a minute, not the block; at 1 TH/s that card finds a block every 16 hours and never reaches the 100-block vote line (44 blocks in 30 days), which the finality lane must weigh against the 1,000-independent-keys gate.
+
+2. Igneum's 30-day vote window is a level system no other chain has, and it is free: the rungs (first block, 100 blocks for a vote, a signature in a checkpoint, 30 of 30 days, rank by weight, a signing streak) are chain facts from `getFinalityWeights`, cost about 6 agent hours to show across Ember, the address page and Discord, and cannot be topped by a renter inside 30 days.
+
+3. In a 105-post sample of miner joy on Reddit (69 with a room median), the posts that rise highest are the miner's own: "my card paid for itself" at 777 times the room's typical score, the rig photo at 417, the hashrate milestone at 409, against 66 for the network's own milestone and 56 for the first pool payout; so every shareable surface Igneum builds carries the miner's card, rank and days, not the project's number, and the saved block card (4.5 hours) is the first of them.

+7 October 2026. Lane 2 of the final research programme. What the industry started and did not finish, group by group, with one verdict per row: Igneum already has the finished version, Igneum could finish it in hours, or Igneum should leave it. Every figure from a source carries its URL and access date in section 9; every figure from memory is labelled approximate. Hours are agent hours (the project lead's rule: Claude-side work takes hours, never weeks). Nothing here is a token sale.
+
+What this file does not repeat: the ASIC chip history (`docs/analysis/asic-resistance-history.md`), the useful-work verdict and the stored-state candidate (`new-pow.md` sections 3, 6, 7), the ranked frontier ideas (`frontier.md` section 0, 3.10, 3.11), and Igneum's own pool design (`docs/plans/pool.md`, `docs/spec/09-pool-protocol.md`). Those are cited, not restated.

+
+Limits of this research: p2pool.observer answered 502 all morning (Monero P2Pool share taken from the miningpoolstats data file instead); Bob Rao's ProgPoW PDF would not extract (his 1.1x to 1.2x figure is cited to EIP-1057); Bitmain's own X9 page was unreachable (the X9 is reported as announced per resellers, unconfirmed shipping); NiceHash's fee and repayment pages are gone (those figures are approximate); Salad's take rate is not published anywhere fetched.
+
+## 1. Group A: proof of useful work
+
+The one question per row: can the useful work be verified cheaper than it is done, and is it sampleable (a nonce picks a random instance the miner cannot steer, with tunable hardness)? The third column the rows keep answering by themselves is whether anyone wanted the output.
+
+### 1.1 The rows
+
+| # | Programme | Attempted, by whom, when | Achieved (numbers) | Left undone | Why it stopped | Verified cheaper than done | Sampleable |
+|---|---|---|---|---|---|---|---|
+| 1 | Primecoin | Sunny King, 7 Jul 2013: header hash is the origin of a Cunningham or bi-twin prime chain | 13-prime 94-digit chain 10 Sep 2013; first length-15 twin chain 30 Mar 2018; height 7,038,822 today | Any use of the primes; GPU resistance (GPU miners by 2014, approximate) | Nobody needed the output; price USD 0.034, "stopped trading on all exchanges"; last release 26 Jan 2021 | Yes, but polynomial: 10 to 15 modexps to verify against millions of sieve steps (approximate) | Yes: the hash fixes the origin, chain length plus fractional remainder tunes hardness |
+| 2 | Gridcoin | Rob Halford, "Proof of Research" live 11 Oct 2014 on BOINC credit | 17 whitelisted projects, 3 greylisted; release 5.5.0.0 on 3 Apr 2026 (78 PRs, 11 contributors) | A verifiable work primitive; consensus moved to pure PoS 2014 to 2015 | Scraper nodes read credit from project servers and sign a superblock; the chain never checks a work unit | Only by trust (an oracle reads a website) | No: the miner picks the project and the unit; the project sets hardness |
+| 3 | Curecoin, FoldingCoin | 2014, Folding@home points paid daily (CURE) or monthly (FLDC on Counterparty) | 1 trillion F@h points by 28 Jul 2019, over 10,000 team members | Verification by anyone but Stanford's servers; Curecoin 2.0 roadmap undated; FoldingCoin asset archived, site gone | Tip jar on a centralised stats feed; token value fell under the electricity (approximate) | Only by trusting F@h | No: F@h assigns the work |
+| 4 | Aleo PoSW to synthesis puzzle | Proof of Necessary Work (Kattis, Bonneau, 2020/190); testnet 3 coinbase puzzle 2023; mainnet 17 Sep 2024 on AleoBFT with the puzzle outside consensus; ARC-41 synthesis puzzle | 750 M proofs per second and over 44,000 provers on testnet 3 (Messari excerpt); 2/3 of coinbase to provers; about 16 pools took close to 90 percent of puzzle rewards; ARC-46 (31 Jul 2025) demands 100,000 ALEO staked per solution, 2,500,000 by 2027 | The original promise: energy that produces proofs of real state. The puzzle proves nothing the network uses | A BFT validator set gives finality; the puzzle survives only to pay hardware and keep a prover fleet warm; proving centralised on the same path as mining | Yes (SNARK verify in milliseconds) | Yes (epoch hash plus nonce, target tunable). Useful: no |
+| 5 | Ofelimos | Fitzi, Kiayias, Panagiotakos, Russell, eprint 2021/1379, CRYPTO 2022: doubly parallel local search, every step a hashed PoW unit | A security proof in the backbone model; WalkSAT variant "competitive with vanilla WalkSAT" | Any deployment; who submits problems and pays; the search's own efficiency (FRLS follow-up 14 Nov 2025 calls DPLS "particularly wasteful") | Economics and operations, not the proof | Yes (each step is a cheap check) | Partly: the step is nonce-bound, the instance comes from a client pool, so hardness is tuned on the hash part |
+| 6 | PoW from worst-case assumptions | Ball, Rosen, Sabin, Vasudevan, eprint 2017/203 and 2018/559: Orthogonal Vectors, 3SUM, APSP with a delegation verifier | The conditions: worst-case to average-case reduction, non-amortisability, fast verification | Any implementation or benchmark; a buyer for random OV instances | The instances must be drawn from a distribution no real problem has; polynomial blow-ups | Yes (near-linear verify against quadratic solve) | Yes by construction. Useful: no in practice |
+| 7 | Filecoin PoRep and PoSt | Protocol Labs, mainnet Oct 2020: seal a 32 GiB sector (hours of CPU plus 20 to 30 min GPU SNARK, 128 to 256 GiB RAM), then daily WindowPoSt | Utilisation 29 percent (Q1 2025), 36 percent (Q3 2025), 1,110 PiB of real data on 3.0 EiB committed; raw byte power 3.01 EiB (29 Sep 2025) to 1.35 EiB (14 Sep 2026), down 55 percent; 99.5 percent of Q3 2025 fees were penalties | Paid demand; two thirds of proved bytes were zero-filled capacity; the chain now pivots to PDP hot storage (May 2025) that earns no consensus power | Sealing cost was paid by emission, not customers; when rewards fell providers left | Yes (one seal, then a sub-second daily proof) | Yes (random leaf challenges per deadline). The only row that held both for a real good, at hours per 32 GiB |
+| 8 | Chia proof of space | Chia Network, mainnet May 2021: plots of random tables, challenge per signage point | 1.5 EiB to 15 EiB in May 2021 alone, peak 36.5 EiB Jul 2021; a k32 plot needs 1.3 TiB of SSD writes; pooling Jul 2021; compression Jan 2023; under 4 EiB effective and under 3 EiB raw in Sep 2026 (about 10 percent of peak); XCH USD 1.36 against a USD 1,934.51 peak; Chia 3.0 (27 Feb 2026) resets plots to 1 GiB k28 with a 256-day phase-out | Anything stored; the space holds nothing | Price down 99.9 percent, reward per TB collapsed, no use for the plots | Yes (a few hashes) | Yes (challenge, plot filter, k). Useful: no |
+| 9 | Flux, Akash | Compute markets beside a coin: Flux (2018 as ZelCash, 7,015 nodes on 5 Oct 2026 against a 14,000 peak, no published revenue in six years, "PoUW v2" Oct 2025 = hardware benchmarking); Akash (Q1 2026 lease revenue USD 253,250, 58 providers, 84 GPUs in use of 334) | Node counts, not verified work | A chain that checks the compute; InFlux Technologies entered administration 4 Sep 2026 | Block rewards pay for idle capacity; demand is two to three orders under the subsidy | No (reputation and benchmarks) | No (customers pick the job) |
+| 10 | Dynex | 2022 to 2026, "neuromorphic quantum computing cloud", DynexSolve | A WIPO patent (14 Nov 2024); market cap USD 119,386, down 99.9 percent; a "phase-out of the utility token" toward a securities structure | A checkable claim: no public code shows the chain checking that a QUBO instance was solved | The useful-work claim was never made verifiable | Unknown, treat as not verified | Not sampleable |
+| 11 | Qubic | 2024 to 2025 "useful PoW" (Aigarth training); from Jun 2025 the work was Monero RandomX hashing sold for QUBIC buybacks | Under 2 percent of Monero in May 2025, over 25 percent by late Jul, 51 percent claimed 11 to 12 Aug 2025; 63 of 122 blocks (3,475,729 to 3,475,850); 6-block reorg 12 Aug (about 60 orphans); 18-block reorg 15 Sep 2025 (117 transactions, past Monero's 10-block lock) | Any verification of the AI claim; no Monero consensus change by Sep 2025; miners moved to P2Pool, exchanges raised confirmations | The "useful" work was a token buyback funded by attacking another chain | The RandomX part: yes, and useless by design. The AI part: no | The AI part: no |
+| 12 | Bittensor subnets | 2023 onward, validators score miners off-chain, Yuma consensus; dTAO 13 Feb 2025 | Over 120 subnets (Mar 2026); 24 with commercial income, USD 28 M to 35 M ARR estimated (Sep 2026); validator reward correlates with stake at 0.80 to 0.95, miner reward with performance at 0.10 to 0.30 (64 subnets, 6.66 M events); weight copying fixed by commit-reveal (May 2024); Quasar (SN24) collapsed Aug 2026 on a plagiarised model | Proof of anything; usefulness is judged, not proved | By design: a stake-weighted reputation market with emission attached | No (judged) | Partly (validators pick queries, no nonce, no hardness knob) |
+| 13 | Proof of inference, 2024 to 2026 | Gensyn Verde (refereed delegation, about 60 percent overhead on Llama-3.1-1B, needs one honest provider); Hyperbolic proof of sampling (re-execute a fraction, slash); Ambient proof of logits (claimed 0.1 percent overhead, testnet still pending Apr 2026); Inference Labs (self-reported 950 M proofs); zkML (hundreds of seconds per query for billion-parameter models); Boundless PoVW (pays ZKC per proved cycle, a sample proof 2 to 5 min at USD 0.04 to 0.17); Succinct (over 6 M proofs in 2025, 25 provers) | Proving networks exist and are run by a few dozen operators | A job that is both random and wanted; a verifier cheaper than a referee, a chip or a slashing game | zk proving costs 10^3 to 10^4 times the inference; the cheaper schemes trust something | zk: yes at 10^3 to 10^4 overhead. The rest: only by trust | zk: yes if nonce-bound. Nobody has made the job random and wanted |
+
+The 2025 to 2026 literature says the same thing from three sides. The SoK (eprint 2025/1814, over 50 constructions): "PoUW is actually not as useful as expected, since the economic and societal utility do not contribute to the security budget". Pass (arXiv 2606.06700): a majority attack still costs the block reward. Basu (arXiv 2606.04819): Pearl's 24 EH/s network of about 320,000 GPU-equivalents at about 112 MW "produces zero useful AI computation".
+
+### 1.2 The pattern, and what Igneum finishes
+
+Every programme that passed both tests (cheap verify, sampleable with tunable hardness) did so by making the work useless: Primecoin chains, Chia tables, Aleo's synthesis puzzle, Filecoin's capacity sectors, Boundless cycles. Every programme that kept the work useful gave up verification: Gridcoin, Curecoin, Bittensor, Flux, Akash, Qubic, Dynex. Filecoin alone held both for a real good and paid with hours of sealing per 32 GiB and a network two thirds filler.
+
+**What Igneum already finishes (two rows).**
+
+| Row | The unfinished promise | Igneum's finished form | Evidence in the repo |
+|---|---|---|---|
+| 4, Aleo PoSW and Proof of Necessary Work | Energy that produces succinct proofs of real state, paid from issuance | Every block is proven by miners in chunks and aggregated 20 to 60 s behind the tip; the provers are paid 20 percent of emission by sortition by weight; the proof is of the chain's own execution, not a synthetic circuit | CLAUDE.md design paragraph; lane 4's finding 1: the proof verified in consensus is the fix for the one line where a majority earned more than it spent (11,636 IGN an hour at 51 percent of blocks); switch `proving_consensus_verify_daa` ships off by default in 0.3.16, activation a decision owed |
+| 13, Boundless PoVW and Succinct | Pay per verified unit of proving, meter the cycles, let a market set the price | pgas cycle metering through the proving share; external jobs 90/10 provers and burn, priced in dollars, settled in the token | frontier.md 3.10 "PoVW-like cycle metering through pgas"; CLAUDE.md fee lines |
+
+**Why the split is the finished form.** The bound from `new-pow.md` 3.1 is the reason nobody closed the loop: the useful fraction of a proving-as-lottery scheme is (proving work per segment) over (network hashes per segment), 8 percent at 1 GH/s and 0.08 percent at 100 GH/s, because gas sets one and the security budget sets the other. Aleo found the same wall and decoupled on 17 Sep 2024 ("provers do not participate in consensus or produce blocks"), then had to add a stake gate in 2025 because the puzzle centralised on the fastest prover. Igneum's split carries no stake and no coupling: the lottery is a Poisson process on a random program (the Kaspa developer's objection in frontier 3.10 stays satisfied), the proving is paid by sortition by weight, and the one line where the split was NOT yet finished (a majority prover pool earning more than it spent) is closed by verifying the proof in consensus. Until that switch is on, Igneum's split is Aleo's 2024 form; with it on, it is the form Aleo could not reach without a validator set.
+
+**What Igneum should leave.** Rows 1 to 3, 5, 6, 9 to 12: 0 hours. The only adjacent idea with value was taken by lane 8 as scheme C (the dataset is the keyed execution state, the class v5 candidate), which answers rows 7 and 8 by making the stored thing the chain itself, at an unchanged hash rate; it is already judged and not repeated here.
+
+## 2. Group B: memory-hard and ASIC-resistance programmes that stalled
+
+The chip history is done in `asic-resistance-history.md`. This section covers only what was started and abandoned, and ends each row with what Igneum's hourly random program, latency shadow and class ladder already encode, and what they do not.
+
+### 2.1 The rows
+
+| # | Programme | What was planned | What shipped | What was left on the table | Why it stopped |
+|---|---|---|---|---|---|
+| 1 | Ethash successors | EIP-969 (David Stanfill, 3 Apr 2018): five FNV primes of Hamming weight 7 to 8 against the Antminer E3, fork at block 5,550,000 with 30 days' notice; ProgPoW as "Ethash 2" | Nothing on Ethereum. ETC's Etchash (ECIP-1099, Thanos, block 11,700,000, Dec 2020) halved DAG growth to keep 3 to 6 GB cards | The FNV tweak (Stagnant), the DATASET_PARENTS increase Least Authority asked for, any epoch recalibration on mainnet | No client team adopted EIP-969 for a chip expected to be short-lived; attention moved to ProgPoW; PoW ended at the Merge 15 Sep 2022 |
+| 2 | ProgPoW, EIP-1057 | Hold the chip gain to 1.1x to 1.2x by saturating the whole GPU datapath (random math, 16 KB cache, DAG loads, keccak-f800) | Two audits (Least Authority 9 Sep 2019: accurate to design, five suggestions, the light-evaluation attack named; Bob Rao: 100 MB on-die SRAM "possible", DRAM 3 pJ per bit against 0.3 on chip); KawPow (6 May 2020), FiroPoW (26 Oct 2021), Zano, Sero, Quai (29 Jan 2025) | Activation on Ethereum: tentatively accepted 4 Jan 2019, "accepted and final" 21 Feb 2020, petition EIP-2538 27 Feb, kik's 64-bit-seed exploit about 4 Mar, off the fork schedule 6 Mar 2020; authors reposted it 11 May 2020 saying "we do not recommend" deployment | Governance (a revival read as stealth), the PoS roadmap, a bug two weeks after "final", the authorship conflict (Core Scientific, Linzhi's 3x to 8x claim with no evidence) |
+| 3 | RandomX v2 | A tweak after seven years: program 256 to 384 instructions, 16 AES mixes in place of XOR, dataset prefetch 2 iterations ahead; work per hash up 52.9 percent (4,456,448 to 6,815,744 ops) to re-match CPU to memory latency | Library PR 317 merged 17 Feb 2026 (SChernykh); commitments PR 265 merged 8 Sep 2023 | Activation: Monero PR 10038 (v17) open since 14 Aug 2025, pending review 19 Sep 2026, no date | The chip came first: Antminer X5 Sep 2023 (212 kH/s, 1,350 W); X9 1 MH/s at 2,472 W listed as "August 2026, delayed" per resellers, unconfirmed shipping; the Qubic episode used plain CPUs so it forced no algorithm change |
+| 4 | Kaspa kHeavyHash | A hash for optical hardware (Dubrovsky, Ball, Penkovsky, arXiv 1911.05193): shift cost from OPEX to CAPEX; GPU resistance never a goal; chosen by community vote one day before launch | IceRiver KS0 (100 GH/s at 65 W, 2023), then 15 to 21 TH/s boxes; GPUs at 2.2 GH/s left | A GPU lane (never planned); optical mining (no shipping hardware, approximate) | By design. The GPU fleet forked away: Karlsen (FishHash, 4 GB DAG), Spectre (CPU), Pyrin |
+| 5 | Autolykos v2 | Keep the 2 GB table, grow it 5 percent per 51,200 blocks from block 614,400, cap at block 4,198,400 (2,143,944,600 elements) | EIP-0009 at block 417,792 (Feb 2021 approximate); non-outsourceability removed because contract pools bypassed it (Chepurnoy and Saxena, eprint 2020/044) and small miners did not want it | A successor to pool resistance; an answer to HBM FPGAs ("HBM FPGA friendly", Osprey listed ERGO); the growth stops at the cap | Small prize, no chip, the table cap is a policy choice |
+| 6 | Grin's two lanes | Cuckaroo29 for GPUs (90 percent of reward falling to 0 over two years, tweaked every six months), Cuckatoo31+ for chips (10 percent rising to 100) | Four hard forks on schedule; HF4 (about 15 Jan 2021) ended the GPU lane; one chip shipped (iPollo G1, 36 GPS at 2,800 W, Dec 2020) | Obelisk GRN1 cancelled 19 Jul 2019 ("lack of interest and funding", full refunds); Innosilicon G32 announced, never documented shipping; the lean-solver memory claim: Tromp's USD 10,000 linear TMTO bounty claimed 11 Apr 2025 (about half an order of magnitude, not tenfold) | The schedule forced chip makers to choose between a single-use C31 chip and a late C32 chip at a USD 2 coin; network today 3.40 KGps on GPUs |
+| 7 | Equihash parameter programmes | Zcash: a parameter change "ideally deployed by late 2018"; a 2020 PoW migration (ballot 3 Jul 2018: 38 of 64 for migration by 31 Dec 2020). Beam: forks at 6 and 12 months then an "affordable ASIC" (BeamHash III, 28 Jun 2020). BTG: Zhash 144,5 after the May 2018 51 percent attack (388,000 BTG) | Zcash stayed on 200,9 with chips (2019: BCTV14 forced the choice of Sapling over ASIC work); Beam stayed on BeamHash III with GPUs only; BTG forked and was hit again in Jan 2020 | Zcash's migration; Beam's affordable chip; BTG's real problem (rented hash on a small chain) | Governance by poll chose "reduce chokepoints" over resistance; parameter forks do not fix a rentable chain |
+| 8 | Octopus to Ethash | CIP-102 (Chenxing Li, 5 Aug 2022): switch to Ethash "to make it easier for Ethereum miners to switch to Conflux" | Nothing; the CIP has "TBA" for specification and rationale and never left Draft | The AMD support and DAG shrink the forum asked for instead | The community called Ethash "not ASIC resistant" and Octopus "the trademark" |
+| 9 | Blake3 on Alephium | ASIC friendly by design, "just like Bitcoin" | Goldshell AL-BOX (360 GH/s, May 2024 per the aggregator), Antminer AL1 (15.6 TH/s, Jul 2024); the project's own gpu-miner and fpga-miner repos stopped mattering | Nothing, by the project's own view | By design |
+| 10 | Tensor PoW | Komargodski and Weinstein, eprint 2025/685: PoUW from arbitrary matrix multiplication at 1+o(1) overhead; "this blockchain is currently under construction" | A paper (15 Apr 2025, revised 8 Dec 2025). ethresear.ch has no topic matching "tensor core proof of work" | A chain; a measurement of what tensor work costs the honest card against a chip | Nobody measured it before writing it |
+
+### 2.2 The FPGA question, one line per row
+
+| Row | Was the FPGA the first adversary | What stopped it |
+|---|---|---|
+| Lyra2REv2 (Vertcoin) | Yes: a Zynq UltraScale+ at 31.25 MH/s and 24.93 W, 4.3x a Titan Xp per joule (arXiv 1905.08792) | A fork to Lyra2REv3 |
+| X16R (Ravencoin) | Yes: all 16 hashes on one UltraScale+, about 5x a 1080 Ti per joule at 3 to 4x the price | X16Rv2 then KawPow |
+| Equihash 144,5 and 200,9 | Promised in 2018 (a vendor asked a USD 1,000,000 minimum order), no hashrate ever posted | The 2.5 GB table; HBM boards matched GPUs per dollar at best (approximate) |
+| Ethash and ProgPoW | HBM boards existed in 2019; Least Authority: a 10-block period makes "building and loading a bitstream in such a short period (about 2 minutes) impractical" | DRAM latency on cheap boards, HBM cost on fast ones, bitstream churn |
+| Autolykos v2 | Osprey listed ERGO on an 8 GB HBM board; no share figure published | Nothing stopped it; nothing measured it |
+| kHeavyHash | Osprey E300, 14 GH/s at 250 to 500 W, USD 4,999, three VU35P with HBM2, announced 13 Dec 2022 | Overtaken within months by 100 GH/s to 1 TH/s ASICs |
+| RandomX, Cuckoo | No FPGA product ever shipped | A CPU-like core with 2 MB per thread; 512 MB to 1 GB of fast memory per graph |
+
+### 2.3 What Igneum already encodes, and what it does not
+
+| Row | Encoded in Igneum (where) | Not encoded (the gap) |
+|---|---|---|
+| 1 Ethash successors | A dataset that grows on a genesis-fixed schedule with the cache doubling (256 MiB, 512 MiB year 4, 1 GiB year 12); the 4 GB cliff lesson lives in the tier rule ("every number carries its consequences", 8 GB to 32 GB cards); EIP-969's human tweak against a chip is replaced by automatic era draws | The DATASET_PARENTS idea is Igneum's mixer x8 (8 dependent reads per item), which has the fixed shape the chip history calls the 3x factor; the random item derivation (asic-history addition 2) is still open |
+| 2 ProgPoW | The governance death is designed out: every layer is a genesis rule or a reserve, no adoption vote (asic-history lesson 7); the 64-bit-seed class: Igneum's seed is 256 bits and the program is the epoch's; the light-evaluation attack is priced (chip-model-v3, 0.31x bare, 0.92x with the 3x factor); the datapath target is the whole GPU | ProgPoW's 2-minute period was its FPGA defence; Igneum's epoch is 1 h, so a soft-overlay bitstream within the hour is the open lane (asic-history addition 5, the 10 min to 2 h epoch reserve, design on `ca2-epoch`) |
+| 3 RandomX v2 | The lesson is that a tweak after seven years arrives after the chip. Igneum draws era parameters every 6 months from chain state and unlocks families by height, with no human release; the class ladder (95 percent with a floor height, P2) is the only human path and it is for new code, not for parameters | Per-hash program entropy (RandomX's 25x GPU cost, refused on purpose); the random superscalar item derivation; four external audits before launch (RandomX paid USD 141,000; Igneum's cryptanalysis spend of USD 80,000 to 160,000 is a decision owed) |
+| 4 kHeavyHash | The loss of the GPU fleet is the metric: hashrate share by card model from the observer and the January 2027 benchmark (asic-history addition 4) | A published vendor-share number does not exist yet |
+| 5 Autolykos v2 | Pools are wanted (spec 09), so non-outsourceability is nowhere by choice; the dataset grows by rule | Whether Igneum's growth schedule ever caps is a spec 1.13.3 question this lane did not reopen |
+| 6 Grin | Scheduled change without a vote is the shared idea; Igneum's draws are automatic, Grin's were forks | The lean-solver lesson (a memory claim weakened six years later by a bounty) is the reason the mixer and chained cache need cryptanalysis (ledger M7) |
+| 7 Equihash | The rented-hash problem is answered by the 30-day weight finality, not by the hash (section 4) | Nothing |
+| 8, 9 Octopus, Blake3 | Nothing to take | Nothing |
+| 10 Tensor PoW | Measured and retired: scheme B's mm8 shadow costs the honest card 0.056 to 0.70 pJ per multiply-add and moves the chip's edge only from 6.9x to 4.9x, so it is reserve R8 with the two-output correction (new-pow.md 6) | Nothing; Igneum did the measurement the 2025 paper has not |
+| FPGA, all rows | Bitstream churn is encoded as the hourly program; the HBM board is the f = 1 stored-dataset chip in the model (5.1x on GDDR7, 7.5x to 9.2x on HBM3) | The soft-overlay FPGA miner with HBM is unmeasured (addition 5); no row in the chip model for a partial-store chip (addition 1) |
+
+Verdict for the group: nothing in B is a programme Igneum should restart. The three unfinished items that do matter are Igneum's own open rows (random item derivation, external cryptanalysis, the epoch-length and FPGA-overlay measurement) and they are already ranked in `asic-resistance-history.md` 4.3.

+| 1 | Namecoin AuxPoW | Block 19,200, Oct 2011 (vinced; Mike Hearn's outline) | Bitcoin's hashrate for free: about 95 percent of Bitcoin on 12 Jan 2020, about 69 percent (732 EH/s) in Sep 2026; nine pools find blocks (AntPool 34.78 percent, F2Pool 19.99, ViaBTC 19.69, 14-day window to 20 Nov 2025) | One pool (F2Pool) above 50 percent of Namecoin for most of late 2014 to 2016 (approximate; Judmayer et al.: pools "operated at the edge of, and even beyond, the security guarantees" of Nakamoto consensus); the spec's nonce-clash flaw is documented and a replacement BIP never came | Independence: the child's rules are signalled by the parent's pools; Foundry, the largest Bitcoin pool, does not merge-mine it; the name market never grew |
+| 2 | Dogecoin on Litecoin | Hard fork at block 371,337, Sep 2014, after Charlie Lee's Apr 2014 proposal; Dogecoin's own words: "our hashrate has been on a decline" | Hashrate up over 1,500 percent in Sep 2014; DOGE and LTC hashrates correlate at 0.95; about 90 percent of DOGE hashrate from Litecoin pools by 2019; DOGE's share of pool revenue "has long surpassed" Litecoin's (F2Pool data, 7 Apr 2026) | A pool above 50 percent of Litecoin is above 50 percent of Dogecoin by construction | A miner base of its own; any say in the parent's rules |
+| 3 | Myriadcoin and Verge multi-algo | Myriad 23 Feb 2014 (five algos, per-algo floating difficulty, 20 percent of blocks each); Verge (five algos) | Hardware diversity | Verge, Apr 2018: timestamps spoofed about an hour back on the Scrypt lane, per-lane difficulty collapsed, blocks seconds apart, 250,000 to about 20 M XVG (reports conflict); 22 May 2018: Scrypt and Lyra2re both at near-zero difficulty, about 25 blocks a minute, 35 M XVG (about USD 1.8 M); the hard fork between them did not remove the bug; a 560,000-block reorg in Feb 2021 (headline only) | Five lanes made the surface five times wider; each lane is cheaper to rent than the whole |
+| 4 | DigiByte MultiShield, Odocrypt | DigiShield Feb 2014 (block 67,200), MultiAlgo Sep 2014 (145,000), MultiShield Dec 2014 (400,000), Odocrypt Jul 2019 (9,112,320): per-block retarget on all five lanes from a 10-block average, clamps 16 percent down and 8 percent up; Odocrypt rewrites itself every ten days for FPGAs | DigiShield was adopted by Dogecoin (1.6, Mar 2014) and Zcash (v3 variant, approximate); the "93 percent on one algo and 51 percent on the other four" claim is a model, not a measurement | 28 Jun 2026: a dropped validation rule on the Groestl lane let about 1,356 blocks (about 351,000 DGB) be mined, no double spend | A lane with little hashrate still mints one block in five; the ten-day rewrite assumes FPGA owners re-flash and does nothing against a party with many FPGAs |
+| 5 | Elastos, RSK | Elastos with Bitmain 28 Aug 2018 (AntPool, BTC.com); RSK since Jan 2018 (approximate) | Elastos "over 50 percent" of Bitcoin's work (13 Mar 2024); RSK 62.46 percent (Q1 2024), 54.58 (Q3), 56.40 (Q4 2024, AntPool 38.6, ViaBTC 24.3, F2Pool 16.9); Foundry joined | RSK's Armadillo (RSKIP110): detects forks up to about 448 blocks when the attacker has under 9 percent of Bitcoin; "cannot stop a miner creating a blockchain from a past point"; the PowPeg is a federation with HSMs | The attacker rents or bribes three pools, not hardware; Armadillo alerts, it does not finalise; usage stayed small so fees stayed small |
+| 6 | The paper | Judmayer, Zamyatin, Stifter, Voyiatzis, Weippl, "Merged Mining: Curse or Cure?", eprint 2017/791 | One line: merge-mined chains concentrate in fewer pools than the parent, with single pools above 50 percent for months in Namecoin, Huntercoin and Myriad (approximate for the per-coin detail) | | |
+
+### 3.2 Verdict: does Igneum want any of it
+
+No, with four reasons. Igneum's ruling is already "no reliance on another chain"; the question left is whether an Igneum-side auxiliary chain or an "algo slot" has value, and it does not.
+
+| Option | What it would buy | Why not | Hours |
+|---|---|---|---|
+| Igneum as a merge-mined child of another chain | Borrowed hashrate | Ruled out (CLAUDE.md: no other chain in consensus); and the rows show the child inherits the parent's pool concentration and loses its say in rules | 0 |
+| Igneum as a parent for other chains | Nothing for Igneum; a coinbase commitment slot for others | The hash is a new program every hour, so a child cannot verify Igneum work without Igneum's program pipeline, VDF seed and dataset; the vote key per operator would not carry to the child; the only cost is a header field nobody asked for | 0 until asked |
+| An algo slot (a second hash lane) | Hardware diversity | Myriad, Verge and DigiByte show each lane is a separate difficulty controller and a separate rentable surface; Igneum's 30-day vote weight is counted in blue blocks of ONE work unit, so a second lane splits the weight table and the DAA; GHOSTDAG's k is derived from one block rate on one hash | 0 |
+| A share sidechain merge-mined through the coinbase | A pool without an operator | This is the one merged-mining shape with value, and it belongs to section 5 (it is how Monero P2Pool works) | see 5.3 |
+
+## 4. Group D: GPU-friendly finality attempts
+
+The one axis asked: can a renter buy or break finality in a day? Igneum's rule for comparison (CLAUDE.md, finality rule v2): vote weight = blue blocks per vote key over a flat 30-day window, lock at 2/3 of all 30-day weight, so 10 days of 100 percent hashrate reach 1/3 of weight and 20 days reach 2/3; 51 percent never reaches 2/3 while honest miners stay.
+
+### 4.1 The rows
+
+| # | Programme | Attempted | Finished | Left undone | Renter buys finality in a day? |
+|---|---|---|---|---|---|
+| 1 | Decred hybrid | Feb 2016: tickets vote on every block, 3 of 5 called tickets must sign; 40,960 ticket pool, 28-day average wait | A PoS veto on every block, stakeholder-voted forks, a treasury; stake locked rose from 50 percent (Dec 2019) to 64 percent (Dec 2022) while hashrate fell about 6x; DCP-0011 (BLAKE3 and ASERT) and DCP-0012 (PoW to 1 percent of subsidy) active at block 794,368 (Aug 2023) because PoW was "used to maliciously manipulate Decred markets" | No finality gadget; PoW is a 1 percent stipend | No for reorgs (needs about half the live ticket pool, roughly 30 percent of DCR bought over 28-day cycles, approximate); yes for withholding and censorship, since the hash layer is thin |
+| 2 | Horizen delayed-block penalty | After the 2 Jun 2018 51 percent attack (over USD 500,000, 36 fake blocks): a block n late owes about n(n-1)/2 extra blocks (approximate formula); shipped in ZEN 2.0.16, late 2018 | A reorg tax on hidden chains | Partition safety: the smaller honest side looks like a hidden chain; Horizen now calls itself an L3 on Base and the PoW mainchain is winding down (approximate) | Yes under 5 blocks and for public mining; a deep secret reorg costs quadratically more. A tax, not finality |
+| 3 | Kaspa merge depth and finality depth | MERGE_DEPTH_DURATION 3,600 s, FINALITY_DURATION 43,200 s, PRUNING 108,000 s in rusty-kaspa constants; at 10 BPS since Crescendo (about 5 May 2025): merge depth 36,000 blocks, finality depth 432,000 | Online nodes refuse a reorg deeper than 12 hours; a block cannot merge a side chain older than an hour | Both rules are local and subjective; a node syncing later follows the heaviest DAG; DAGKnight (eprint 2022/1494) is in PRs (1104, 1124, 1132) and not on mainnet | Partly: under 12 hours yes with over 50 percent of an ASIC-only hash (thin rental supply); over 12 hours the attacker splits the network instead |
+| 4 | Conflux Tree-Graph, GHAST, PoS votes | GHAST (arXiv 2006.01072): confirmation in O(d log 1/epsilon), about 3d against about 360d for six Bitcoin blocks; adaptive weight switches to a conservative mode under a liveness attack | CIP-43 (Hydra, about 28 Feb 2022): a PoS chain of staked CFX (1,000 CFX per vote) votes on pivot blocks "to protect against 51 percent attacks from PoW" | GHAST alone is probabilistic; the PoS committee is the finality | No for finalised pivot blocks; yes inside the trailing minutes |
+| 5 | Ethereum Casper FFG over PoW | EIP-1011 (20 Apr 2018): 1,500 ETH minimum deposit, 50-block epochs, "never revert finalised blocks"; testnet 31 Dec 2017 | Nothing on mainnet; the Berlin Eth2 workshop (Jun 2018) discarded hybrid Casper for the beacon chain | The hybrid itself | Under the design: no for finalised checkpoints (slashing two thirds of deposits), yes inside an epoch. Dropped because "the limited bandwidth of the EVM constrained the size of the validator set", forcing whale-sized deposits |
+| 6 | Bitcoin Cash Avalanche pre-consensus | Sechet, Sep 2018 (approximate) | On BCH: nothing. On eCash (XEC): post-consensus finality 14 Sep 2022, staking rewards 15 Nov 2023, pre-consensus 15 Nov 2025 at block 923,347 ("finalise transactions in under 3 seconds"); staked XEC 69.4 B to 242 B in the year to Jul 2024, 350 B+ by Jul 2026; 33 to 94 nodes; 100 M XEC minimum per stake UTXO with 2,016 confirmations | BCH never got it; no slashing (approximate); on quorum loss the chain falls back to heaviest work | No while the quorum holds; yes if the attacker knocks the about 94 Avalanche nodes offline |
+| 7 | Ethereum Classic MESS | ECIP-1100, active at block 11,380,000 (Oct 2020) after three Aug 2020 reorgs (3,594, 4,446 and 7,278 blocks; 807,000 and 465,444 ETC double spent): a capped polynomial, up to 31x the local chain's difficulty for a segment older than about 7 hours | No deep reorg on ETC after Oct 2020 (approximate) | Deactivated by ECIP-1110 at block 19,250,000 (Spiral, Jan 2024) because "the costs now outweigh the risks"; Core-Geth v1.13.0 (15 Sep 2026) re-enabled it with 96 unreviewed commits, miners rolled back the same day, PR 53 (merged 6 Oct 2026) restored the deactivation | With MESS on: no for reorgs older than 7 h, yes for short ones, and an eclipse strands a victim. Off today: yes, plain PoW |
+| 8 | Zcash trailing finality layer, Crosslink | ECC's TFL book (2023, Wilcox and Hopwood); Shielded Labs builds zebra-crosslink, "a proposed upgrade"; BFT PoS finalises a trailing prefix, PoW continues if BFT stalls | An incentivised feature net; milestone 4 of 5 in early 2026 (search summaries) | Mainnet: nothing by 7 Oct 2026 | Today: yes (plain Equihash, rentable, approximate). Under Crosslink: no for finalised blocks, yes inside the trailing window |
+| 9 | Nervos CKB | NC-Max (eprint 2020/1101): two-step confirmation, 3.0 to 6.6 times shorter latency; Eaglesong "ASIC neutral", first chip four months after launch | NC-Max runs since launch | No finality layer; no hybrid plan | Yes in principle; ASIC-only supply is thin |
+| 10 | Dash ChainLocks, Syscoin, Komodo | Dash DIP-0008 since block 1,088,640 (Jun 2019): an LLMQ of 300 to 400 masternodes signs the first block seen, 240 signatures lock it; Syscoin copied it over Bitcoin merged mining (4.2.0, block 1,004,200, 30 Apr 2021); Komodo notarises to Bitcoin then Litecoin every 10 to 25 minutes through 64 elected notaries | Finality in about one block (Dash) | A second validator set bought with coins (1,000 DASH per masternode, approximate) or elected (Komodo's 64) | No for locked blocks |
+
+### 4.2 The comparison on the one axis
+
+Every finality on a PoW chain that holds in practice is a second validator set paid in coins: Decred tickets, Dash and Syscoin masternodes, eCash stake, Conflux PoS, Komodo notaries, Casper FFG's 1,500 ETH deposits. Every rule that only reweights work (Horizen's penalty, MESS, Kaspa's 12-hour depth) is subjective and partition-sensitive, and two of the three have been switched off or are winding down.
+
+Igneum is the only design in the table whose second set is the miners themselves, weighted by past blocks, with no coins staked. On the one axis:
+
+| Attacker | Decred | Kaspa | MESS (on) | eCash | Igneum |
+|---|---|---|---|---|---|
+| Rents 100 percent of hashrate for one day | Withholds, cannot reorg | Reorgs up to 12 h | Reorgs up to about 7 h | Nothing while the quorum holds | Reorders inside the 90-second window (horizon 1, finding 3), nothing past a certificate; has 1/30 of a window's weight at the end of the day, needs 2/3 |
+| Rents 100 percent for 20 days | Same | Splits the network | Same as above | Same | Reaches 2/3 of weight only if every honest miner has left; with honest miners staying, 51 percent never reaches 2/3 |
+| Buys coins | Buys tickets over 28-day cycles | n/a | n/a | Buys stake | Nothing; weight is not for sale |
+
+What is unfinished in Igneum's own finality is Igneum's, not the industry's: the signed LEAVE item (0.3.16) after the 6 October pause (42.7 percent of the frozen voter table left in three minutes and the pause held a window), the 10-percent-per-hour removal rule, weight-gated deep fork choice and vote-or-burn (horizon 1, findings 2 and 3). The one lesson this group adds: every subjective reweighting rule was eventually turned off by its own chain (MESS twice), so the "no hidden-block n^2 penalty" removal in Igneum's rule v2 was the right side of the history.
+
+## 5. Group E: decentralised pools
+
+### 5.1 The rows
+
+| # | Programme | When, by whom | Design | What it achieved (numbers) | Why it stalled or died | Left undone |
+|---|---|---|---|---|---|---|
+| 1 | Bitcoin P2Pool | Forrest Voight, 2011 | A share chain with a 30-second share period; window = shares worth 3 blocks of work or 8,640 shares (72 hours), whichever is smaller; the generation transaction pays the window; 0.5 percent to the finder, no operator | 350 GH/s in Apr 2012 (about 2 to 3 percent of Bitcoin, approximate); 1.4 TH/s by Jul 2013; today 915 TH/s on 14 payout addresses (about 0.0001 percent of about 950 EH/s, my division); last commit 19 Sep 2018 | Variance for small miners (a small miner rarely lands a share in the window), dust (one output per miner per block), a 20x faster chain so stales are "common and expected", a 2012 orphan flaw, a Python 2 node on a full bitcoind | Payout aggregation, per-miner vardiff inside the chain, a maintained node (c2pool's C++ rewrite says "v37 is design-stage, do not run in production") |
+| 2 | Monero P2Pool | SChernykh, Aug 2021 | A sidechain merge-mined with Monero: 10-second blocks, PPLNS up to 2,160 blocks (6 hours), uncles at 20 percent less, payouts in the Monero coinbase, 0 percent fee, about 0.00027 XMR minimum, every miner runs monerod; three chains (main, mini, nano since v4.7, 30 May 2025); Tari merge mining since the 12 Oct 2024 fork | Today: main 441 MH/s and 561 miners, mini 25.3 MH/s and 1,997, nano 4.8 MH/s and 962; 471 MH/s and 3,520 miners in all, 7.7 percent of 6.13 GH/s (my division); against SupportXMR at 2.35 GH/s (38 percent) and HashVault at 672 MH/s (11 percent); the Monero GUI bundles it | A local node is mandatory; below about 15 MH/s of pool hashrate "not all shares will result in payouts"; three chains fragment the hashrate; share has fallen from double digits (approximate) to 7.7 percent | A light mode; cross-chain vardiff; payout smoothing for mini and nano miners |
+| 3 | Stratum V2 | Braiins (Moravec, Capek) with Matt Corallo, 2019, from Corallo's BetterHash draft (12 Mar 2018, never past specification) | Binary, Noise-encrypted; Mining, Job Declaration (renamed from Job Negotiation) and Template Distribution sub-protocols; the SRI translation proxy | SRI v1.0.0 tag 23 May 2023, v1.12.0 17 Sep 2025; native V2 pools: Braiins (JD "since about 2020"), DEMAND (public Nov 2025), ckpool (31 Jul 2026); firmware: Braiins OS, Bitaxe ESP-Miner v2.14.0 (Jun 2026), Auradine; stock Antminer and WhatsMiner are V1 only; the first known Job Declaration block is 955,318 on 25 Jun 2026 (DMND, GoMining's template); seven pools holding about 75 percent of hashrate joined the working group on 7 May 2026 "still in testing" | No primary number for SV2 hashrate; the two V2-native pools mined 753 and 1 of 52,297 blocks in the last year, so under 2 percent on SV2 at all and far under 0.1 percent on JD (approximate conclusion) | Stock firmware, JD at any top-five pool, Windows template building ("not yet supported"), a payout scheme that rewards miner-built templates, any measurement of adoption |
+| 4 | Braiins Pool | Slush Pool, Nov 2010; the first anti-hopping score (Rosenfeld 2011, section 3.1) | FPPS "0 percent fees with Braiins OS", 2 percent otherwise; on-chain or Lightning payouts | 13.91 EH/s, 177,359 workers, 13,112 users today; 753 of 52,297 blocks (1.44 percent) in the last year | The oldest pool and the SV2 author holds 1.4 percent | SV2 adoption did not become hashrate |
+| 5 | Ocean | Luke Dashjr, 28 Nov 2023, USD 6.2 M seed led by Jack Dorsey | TIDES: a share log eight times the difficulty deep, each share rewarded about eight times, 99.9665 percent chance of at least once, paid in the coinbase itself; DATUM (29 Sep 2024): the miner runs a gateway and a full node and builds its own template, 50 percent fee discount (2 percent, 1 percent with DATUM) | First block's coinbase came from a test server and paid nobody (4 Dec 2023 post-mortem); today 28.97 EH/s, 2,522 users, 1,553 blocks of which 1,316 DATUM (85 percent, my division), 1,073 of 52,297 blocks (2.05 percent) in the last year; Tether committed hashrate Apr 2025 | The template fight: Bitcoin Knots filtered inscriptions and Samourai transactions at launch; Dashjr resigned 29 Aug 2026 after the "mining divide" | A single operator still runs TIDES accounting, share verification and the generation transaction; non-DATUM miners get the pool's policy |
+| 6 | DEMAND | Guru Protocol Ltd (company 15235937), Alejandro De La Torre; launched Mar 2025 on the SRI, public Nov 2025 | "The world's first Stratum V2 mining pool"; SLICE pays subsidy by hashrate and fees "by the value you built"; Rootstock merge mining | 1 block in 19 months | Scale | SLICE at size |
+| 7 | Kaspa pools | Today: 334.9 PH/s; F2Pool 98.14 PH/s (29.3 percent), HumPool 92.95 (27.8), ViaBTC 37.89 (11.3), K1Pool 16.74 (5.0), WhalePool 13.67 (4.1); top two hold 57 percent | All PPLNS or PPS+ with 0.5 to 4 percent fees | No non-custodial or P2Pool-style pool; solo bridges only (K1Pool Solo, Kaspa-Pool SOLO, HeroMiners SOLO); no pool page explains which DAG blocks pay (approximate: blue blocks in the mergeset, red blocks earn nothing) | n/a | A decentralised pool on a DAG chain has never been built |
+| 8 | SmartPool | Luu, Velner, Teutsch, Saxena, eprint 2017/019, USENIX Security 2017 | Shares in batches ("1 transaction can claim 1 million shares") in an augmented Merkle tree; the contract samples k random paths; a caught cheater is paid nothing | ETC first ("over 30 blocks"), Ethereum closed beta Jun 2017; 105 blocks across both, peak 30 GH/s from 2 miners (about 0.05 percent of Ethereum, approximate); cost 0.6 percent of block rewards in transaction fees | Gas prices rose about ten-fold in 2017 and the claim cost passed the fee it was meant to beat; the beta never opened; the team founded Kyber; PoS removed the target (all approximate: smartpool.io is dead) | Any successor with hashrate; the opposite approach (Autolykos v1's non-outsourceable puzzles) was bypassed with collateralised contracts (eprint 2020/044) and removed |
+| 9 | Non-custodial on GPU chains, 2024 to 2026 | Ravencoin: 2Miners 292.67 GH/s with "51 percent of recent blocks", Hiveon 621 GH/s, no P2Pool; Ergo: 2Miners 303.14 of 491.76 GH/s (61.6 percent), no P2Pool; SoloPool.org sells solo mining at 1.5 to 2 percent "no pool wallet, no balances" | | Outside Monero every "non-custodial" offer is solo with a stratum bridge, not pooled variance reduction | | |
+
+Share verification cost, from the sources: a Scrypt proxypool spends "around 50 percent of the server's CPU time" checking shares; RandomX light mode on an i9-9900K verifies 1,160 H/s on 16 threads, so a core checks about 70 shares a second (fast mode about 700); Bitcoin SHA256d is microseconds per share (approximate, 10^5 to 10^6 per core). Igneum's pool v0 checks every share on the CPU warp verifier at 1.35 ms isolated and 2.1 ms under load, 480 to 740 per core (`pool.md` section 5), which is RandomX-fast-mode class, 1,000x a SHA256 share.
+
+The payout pattern: FPPS won on Bitcoin because large pools carry variance and sell certainty (Foundry about 30 percent, AntPool about 19, ViaBTC 14, F2Pool 10, d-central 2026); every non-custodial design (P2Pool, Eligius CPPSRB, TIDES, SLICE) is PPLNS-shaped because a coinbase cannot pay a debt. That is the structural reason non-custodial pools stay small, and it is the reason Igneum's pool is PPLNS.
+
+### 5.2 What Igneum's pool lacks against the best of these
+
+Igneum's pool v0 (`docs/plans/pool.md`, spec 09): newline JSON over plain TCP, mode A templates, every share CPU-verified, PPLNS over 2 blocks of weight, 1 percent fee, payouts by EIP-1559 transfer from the pool's coinbase key after blue confirmation, `state.json` every 15 s, the member's vote key in every header it hashes, the pool holds no key, the member checks seeds, class and era against its own node.
+
+| Axis | Best in the field | Igneum v0 | The gap |
+|---|---|---|---|
+| Operator trust for payout | Monero P2Pool and TIDES pay in the coinbase itself; nobody holds a balance | The operator holds the 80 percent in its coinbase address and pays by transfer at most 16 per round; a crash loses up to 15 s of shares; a dishonest operator can misaccount or withhold | The whole of the trust. Mode C (declared templates) and vote carriage are designed, not built; neither removes the operator from payout |
+| Operator trust for template and vote | DATUM and SV2 Job Declaration let the miner build the template; neither touches governance | The member's vote key rides in every header (no Stratum pool does this); mode C is designed, not built | Transaction choice is the pool's in mode A; the vote is already the member's |
+| Variance | P2Pool main: 6-hour window, 561 miners; Ocean: a window 8 difficulties deep | PPLNS over 2 blocks of weight at 1 block a second: a 2-second window of work. Each share is 2^-s of a block, so a 100 MH/s card at one share per 10 s is paid on every block it has a share in | The window is short because blocks are frequent; variance is a block-time question, not a pool question, and v0 has no number for the income variance of a 100 MH/s member at devnet scale |
+| Share verification | Full recompute everywhere; sampling at high difficulty (spec 9.8 item 5, allowed above shift 8, not built) | 1.35 to 2.1 ms per share, one core per 480 to 740 shares a second, no sampling | One template fetch per member per second is the real limit: 1,000 members is 1,000 `getBlockTemplate` calls a second and 10 MB/s (pool.md section 3) |
+| Transport | SV2 Noise encryption, binary framing | Plain TCP, `binding` sent empty, against spec 9.3's TLS 1.3 | Q67 (polish 3.6): 8 hours |
+| Stats and alerts | 2miners charts, offline alerts, luck | 15-minute samples not persisted, no `/metrics`, no payout history on the page, luck defined inverted | Q68 to Q73: about 17 hours |
+| Finality | No pool in the field has a finality concept | Pays on blueness, says nothing during a pause | Q73: 1 hour |
+
+### 5.3 "Shares as first-class protocol objects, no operator": already in Igneum, partly
+
+| Piece | In Igneum already | Where | What is new |
+|---|---|---|---|
+| Governance weight follows the hasher, not the pool | Yes: the vote key per operator in the header (spec 9.6), pool concentration is not vote concentration | spec 2.2 fork point a5, spec 9.6 | Nothing; this is further than SV2 or DATUM went |
+| An operator-less payout by weight | Yes for the 20 percent: the proving share is paid by sortition by weight from consensus data, no operator | CLAUDE.md, `executor.rs` (pool.md "The 20%") | Nothing for provers |
+| A share the chain can see | No: a share is a pool message, verified by the pool, paid by the pool | spec 9.8 | This is the new thing |
+
+The finished form is Monero P2Pool's, not SmartPool's. SmartPool's on-chain claims died on gas at Ethereum's share rate; at Igneum's 1.35 ms per share verification, a contract that samples k paths per million-share claim would still need the zkEVM to re-derive the program's warp unit per sampled share, which is the one cost the design keeps off the chain. A share sidechain merge-mined through the coinbase extra data is the shape that works: Igneum's coinbase already carries the member's key reveal and the pool's address (pool.md section 2), so the commitment slot exists.
+
+| Finish | What it is | Hours (agent) | Gate |
+|---|---|---|---|
+| A P2Pool-style share sidechain in the pool crate | Shares form a 10-second chain committed in the coinbase extra data; the window's payout is the block's own coinbase split (the execution layer already credits by rule from consensus data for the 20 percent, so the 80 percent split follows the same path); no balance, no operator key; every member runs a node (the design already assumes one, spec 9.1) | about 40 (sidechain 16, coinbase split in the executor 8, member client 8, Devnet 2 crossing 8) | a 3-node fast-time network pays a window with no operator; an operator that drops every share from one member cannot stop that member's payout |
+| Mode C declared templates | The miner builds the block (DATUM, SV2 JD) | 6 (O-9.4 RPC 2, messages 4) | a declared template is paid like any other |
+| TLS and the `binding` field | spec 9.3 | 8 (Q67) | a replayed `authorize` on a second connection is refused |
+
+The verdict for the group: finish the share sidechain, because it is the one unfinished thing in the field that Igneum's existing objects (vote key in the header, coinbase extra data, execution-layer credit by rule, a node per member) make cheap, and nobody has built one on a DAG chain.
+
+## 6. Group F: mining app UX and the "one click" promise
+
+### 6.1 The rows
+
+Minutes to first share are approximate unless a source is named; they count from the download to the first accepted share on a fresh machine with a driver installed.
+
+| # | Product | Install to first share (min, approximate) | Custody | Fee | What it did that nobody else has | What it left undone | State 2026 |
+|---|---|---|---|---|---|---|---|
+| 1 | NiceHash (2014; QuickMiner 2020, approximate) | 5 to 10 | NiceHash wallet, BTC only; 2.5 M users (infobox) | Seller 2 percent, buyer 3 percent (approximate); BTC deposits at or above 0.00005 BTC free, Lightning free above 0.0000001 | A hashpower marketplace: the miner never picks a coin | Custody: 6 Dec 2017 spear-phishing hack, about 4,700 BTC (USD 64 M), Lazarus indicted 17 Feb 2021; repayment completed Dec 2020 (approximate); no node, no wallet of the user's own | Alive |
+| 2 | HiveOS (2017) | 20 to 40 (flash an image on a second machine or drive, make a web account) | Hiveon pool pays the user's wallet | 2 workers free (3 days of stats); USD 0.50 per card per month to USD 3.00 at 6 or more cards; ASIC USD 2 or free with Hiveon firmware; 10 to 50 percent off at 50 to 1,000 workers | Farm-scale remote management, charts over hours, Telegram and Discord alerts, per-GPU clocks | A second machine or a flash drive; a web account; no local-only mode, no wallet, no node | Alive |
+| 3 | Minerstat, Awesome Miner | 15 to 30 | User's pool and wallet | minerstat free to 2 rigs, about USD 1.46 per rig per month on larger plans (approximate); Awesome Miner free to 2 miners, paid from about USD 4 per month (approximate) | Awesome Miner: "up to 200,000 ASIC and 25,000 GPU miners" from one Windows console | Management only; no node, no wallet, no pool | Alive |
+| 4 | Salad (2018) | 5 | Salad Balance, redeemable for PayPal, gift cards, games | Not published | Gaming-PC "earn while idle"; 450,000+ GPUs since 2018; 16,000+ daily active GPUs in 190+ countries today | Mining itself: the site no longer mentions crypto; SaladCloud sells GPU-hours from USD 0.015; the user's take rate is not disclosed; payout in gift cards for years | Pivoted to a compute marketplace |
+| 5 | Honeyminer (2018) | 3 to 5 | Honeyminer balance, paid in BTC | 8 percent for one GPU, 2.5 percent for two or more (approximate) | The first "download, sign in, earn" miner with no settings | Everything else; the site refuses connections on 7 Oct 2026 | Dead (about 2020 to 2021, approximate) |
+| 6 | Cudo Miner (2017) | 5 to 10 | Cudo balance | 1.5 to 3 percent by tier (approximate) | Profit switching on Windows, macOS, Linux | The pivot to Cudo Compute (cloud GPU); docs host unresolvable on 7 Oct 2026 | Pivoted |
+| 7 | Kryptex | 5 ("Download, Launch, Earn"; first payout 1 to 8 hours) | Kryptex balance; withdraw BTC, USDT, ETH, USDC, LTC, BNB, TRX, Volet, Amazon gift cards; 0.00025 BTC minimum | "A small pool fee", unstated | "153,000 GPU and ASIC miners", "10 million+ downloads"; the pool: BTC 4,945 miners at 6.63 EH/s, XMR 37,576 miners at 1.08 GH/s; PPS+ | A balance, not a wallet | Alive |
+| 8 | unMineable | 5 to 10 | unMineable balance, paid in 80+ assets | 1 percent, 0.75 with a referral code (approximate) | Mine any algorithm, be paid in any coin | A balance; conversion risk; no node | Alive |
+| 9 | Bitcoin Core "generate" (2009 to 2016) | 0 (one setting) | The user's own wallet, in the node | None | Node, wallet and miner in one process, the only time it has shipped at scale | Removed in 0.13 (2016) once GPUs and chips made it pointless | Dead |
+| 10 | Monero GUI mining | 0 after sync (Advanced, Mining, Start mining; thread count; local node required) | The user's wallet | None | A wallet with the daemon's CPU miner, and P2Pool bundled and updated per release (nano sidechain 26 Aug 2023, P2Pool 4.18.1 on 6 Oct 2024); the nearest shipped "node plus wallet plus miner" | The GPU (RandomX is CPU work); no tuning, no alerts; the sync wait | Alive |
+| 11 | Kaspa community miners, the big three | 5 to 15 (a command line, a pool, an address) | The pool's | lolMiner 0.75 percent kHeavyHash, 1.0 Karlsen, 0.7 Ethash, 1.5 Autolykos (v1.96a); BzMiner 1 percent most algorithms, 0.5 ETC, 2 on Pearl and Quantus (v100.45, Windows, Linux, macOS arm64, Docker); GMiner 1 percent kHeavyHash, 2 Ethash and KawPoW, 5 Cortex, "charged continuously"; T-Rex 1 percent (2 on Octopus and Autolykos), 730 open issues, no release date shown; NBMiner 1 to 3 percent, last release 42.3 on 2 Sep 2022 | The per-GPU accepted, rejected, invalid and fault line; kernel speed | No node, no wallet, no tuning against a goal, no signed updates; two of the big three stopped in 2022 (approximate for T-Rex) | lolMiner, BzMiner, GMiner alive; T-Rex and NBMiner stale |
+
+Nobody in the table ships a miner that is also a verifying node and a wallet with a GPU worker: Bitcoin Core did it for CPUs in 2009 and removed it in 2016; the Monero GUI does it for CPUs with P2Pool bundled; every GPU miner is a kernel plus a pool address, and every "one click" app is a custodial balance.
+
+### 6.2 Ember against the field
+
+Ember's state is from `polish.md` 3.1 and 3.10: a Rust engine runs `igneumd` and one GPU worker per card, serves a tokenised local dashboard, Welcome, Cards, Address, the one-time key sheet, Start mining; Ember Tune measured 37 to 41 percent more hashes per watt on PC 1; signed, hash-checked, rolled-back updates with a safe-moment rule; no dev fee in pool mode, a 1-in-100 template solo; pool mode is design only (pool.md section 7).
+
+| Axis | The field's best | Ember today | Past or behind |
+|---|---|---|---|
+| Node, wallet and miner in one process, GPU | Nobody (Monero GUI for CPU) | Yes: `igneumd`, the worker, the key and the address in one app | Past |
+| Custody | Direct-to-wallet only at P2Pool and HiveOS; every one-click app holds a balance | The coinbase pays the user's own address; the vote key never leaves the machine | Past |
+| Governance | Nobody | The vote key in every header the card hashes | Past |
+| Updates | Unsigned zips (the kernel miners); NiceHash and HiveOS auto-update inside an account | Ed25519-signed manifests, sha256, staged, rolled back after 90 unhealthy seconds, a safe-moment rule | Past |
+| Tuning | HiveOS per-GPU clocks by hand; Nanominer's watchdog | A goal with the money consequence on screen, hill climb, 37 to 41 percent per watt | Past |
+| Fee | 0.5 to 3 percent dev fees; 1 to 8 percent custodial takes | 1 percent template dev fee solo, 0 in pool mode | Past |
+| Install to first share | NiceHash, Honeyminer, Kryptex: about 5 minutes with one interstitial | Windows: SmartScreen interstitial, per-user install, a firewall UAC prompt 20 to 50 s in; Mac: an ad hoc signature that macOS 15 refuses without Privacy and Security, Open Anyway (Q3, Q14, Q15); the Windows installer pipeline is dead on GitHub billing (Q80) | Behind: three prompts against one, and no Windows build until Q80 |
+| Earnings | NiceHash's fiat per day on the main screen | "£0.00 earned" first; mined IGN never shown (Q18) | Behind, 2 hours |
+| History and alerts | HiveOS hours of charts and Telegram alerts | A 10-minute strip; no outbound alert (Q16) | Behind, 4 hours plus an alert hook |
+| Per-card faults | lolMiner's status line | "N blocks" per card; `mismatched=` and `faults=` never reach the row (Q13) | Behind, 2 hours |
+| Remote view | HiveOS, NiceHash Rig Manager | None for the owner (the console is the operator's) | Behind; not ranked here |
+| Pool mode | Every miner | Design only | Behind; the share sidechain of 5.3 is the finish |
+| Finality on the surface | Nobody | Nothing during a pause (Q2) | Behind, 3 hours, and nobody else has the concept |
+
+The honest line: Ember is the first app to ship the thing the table says nobody shipped (node, wallet, GPU miner, own key, signed updates, no custody), and it loses to a 2018 Honeyminer on the sixty seconds between download and first share. The first-run fixes are one Developer ID and one Authenticode certificate (Q3, a the project lead decision) plus the Q80 installer builder; the rest of the behind rows are 11 hours.
+
+## 7. Verdict table
+
+| Group | Unfinished item | Who could finish it | Igneum has it | Hours on Igneum | Recommend |
+|---|---|---|---|---|---|
+| A | Energy that produces proofs of real state, paid from issuance (Aleo's 2019 promise) | A chain with a prover network and no validator set | Yes once the proof is verified in consensus (`proving_consensus_verify_daa`, 0.3.16, off by default) | 0 beyond the activation decision | Already done; activate |
+| A | Pay per verified unit of proving at a market price (PoVW) | Boundless, Succinct, Igneum | Yes (pgas metering, 90/10 external jobs) | 0 | Already done |
+| A | Useful work verified cheaper than done AND sampleable AND wanted | Nobody in 13 years | No, and the bound says why (0.08 percent useful at 100 GH/s) | 0.5 (the ledger row beside F13, new-pow.md rank 8) | Skip |
+| A | Stored data as the work (Filecoin, Chia) without filler | Lane 8's scheme C | Partly (class v5 candidate, judged) | per new-pow.md rank 1 (16) | Not this lane's call; already ranked |
+| B | A tweak that lands before the chip (RandomX v2 merged, unscheduled; ProgPoW dead on governance) | A chain whose parameters move without a vote | Yes (era draws every 6 months, families by height, the class ladder) | 0 | Already done |
+| B | The random item derivation and external cryptanalysis of the mixer | Igneum | No | per asic-history 4.3 additions 2 and 3; the spend (USD 80,000 to 160,000) is a decision owed | Finish, through the existing ranking |
+| B | The FPGA overlay measurement and the epoch-length reserve | Igneum | Partly (reserve designed on `ca2-epoch`) | per asic-history addition 5 | Finish, through the existing ranking |
+| B | Tensor-core PoW measured against a chip | Igneum did it (scheme B) | Yes, retired to reserve R8 with the two-output correction | 1 (new-pow.md rank 5) | Already done |
+| C | A merged-mining BIP that replaces the 2011 spec; any child chain with a say in its parent | Namecoin, RSK | n/a (ruled out) | 0 | Skip |
+| C | An algo slot or an Igneum-side auxiliary chain | Nobody should | No | 0 | Skip, with the reasons in 3.2 |
+| D | Finality on PoW without a coin-bought validator set | Zcash Crosslink (not shipped), Kaspa DAGKnight (PRs) | Yes: miner-only 30-day weight, 20 days at 100 percent hashrate for 2/3 | 0 beyond Igneum's own open rows (LEAVE item, 10 percent rule, weight-gated deep fork choice, vote-or-burn: 0.3.16 and horizon 1) | Already done; finish the own rows |
+| D | A subjective reweighting rule that survives its own chain (Horizen, MESS) | Nobody | Removed on purpose (no hidden-block n^2 penalty) | 0 | Skip |
+| E | A pool with no operator on a DAG chain | Nobody has; Monero P2Pool is the finished form on a chain | Partly (vote key in the header, the 20 percent paid by sortition, coinbase extra data) | about 40 (section 5.3) | Finish |
+| E | Miner-built templates (DATUM, SV2 JD: one block in 52,297) | Igneum's mode C | Designed, not built | 6 | Finish after the sidechain |
+| E | Encrypted member transport | SV2 Noise | No (plain TCP, Q67) | 8 | Finish |
+| E | A pool-as-contract with sampled share verification (SmartPool) | Nobody since 2017 | No | 0 | Skip (1.35 ms per share makes it worse than it was for Ethereum) |
+| F | Node, wallet and GPU miner in one app, own key, signed updates | Nobody; Ember | Yes | 0 | Already done |
+| F | Sixty seconds from download to first share | Honeyminer did it in 2018 | No (three prompts, no Windows build) | 6 plus certificates (Q3); 0 or 4 (Q80) | Finish; the certificates are the project lead's |
+| F | Earnings in IGN, per-card faults, an hour of history, a finality notice | HiveOS, lolMiner | No (Q18, Q13, Q16, Q2) | 11 | Finish |
+| F | Payout in something a gamer can spend (Salad's gift cards) | Salad | No, and the chain says "nothing is bought or sold on devnet" | 0 | Skip until there is a market |
+
+## 8. Three headline findings for the coordinator
+
+1. Every proof-of-useful-work programme that passed both tests (cheap verify, sampleable) did so by making the work useless, and the one exception, Filecoin, ran at 29 to 36 percent utilisation and lost 55 percent of its raw byte power in the year to 14 Sep 2026; Igneum's split already finishes Aleo's 2019 promise, and the only unfinished line (a majority prover pool earning 11,636 IGN an hour at 51 percent) closes when `proving_consensus_verify_daa` is switched on.
+
+2. No pool without an operator exists on any chain but Monero (P2Pool at 7.7 percent, 3,520 miners, 0 percent fee; Ocean at 2.05 percent of blocks with 85 percent of them from DATUM; Stratum V2 job declaration at 1 block in 52,297), and Igneum already holds the three objects that make one cheap (the vote key in the header, the 20 percent paid by sortition, the coinbase extra data), so a share sidechain is about 40 agent hours and would be the first on a DAG chain.
+
+3. Every finality on a PoW chain that held in practice is a second validator set bought with coins (Decred 64 percent of supply staked, eCash 350 B XEC, Dash 1,000 DASH per masternode), and every rule that only reweights work has been switched off by its own chain (MESS twice, Horizen winding down, Kaspa's 12-hour depth subjective); Igneum's work-weighted set needs 20 days of 100 percent hashrate to reach 2/3, so no renter buys it in a day, and the unfinished items are Igneum's own (the LEAVE item and the 10 percent rule), not the industry's.

The same day on that CPU (load 38 to 47): a three-shard block proved shard by shard and aggregated by recursion, 19 min (1,139 s) end to end, 245 to 337 s per compressed shard proof, every proof verified. What is not there: no proof is produced, carried or checked on the chain (the devnet prover is a stub that signs claims), the proving pool pays nobody (row 21), the block proven is far below one shard, and the 60-second figure remains a design target; the pass mark is the standard in `docs/benchmarks/proving-e2e.md`. Second RTX 5090 run, 4 October 2026 evening (job run-20261004-173115): a full shard at the provisional S_p (6.75 M pgas, 60.8 M cycles) executed in 1.63 s, core proof 8.3 s (18.1 MB), compressed proof 10.9 s (1.27 MB, verify 0.040 s); a two-shard block (13.5 M pgas) proved shard by shard (11.7 s and 10.0 s) and aggregated in 2.2 s, 24 s of GPU stages end to end, every proof verified, six tampered witnesses rejected. The two host defects (an abort after the upload, an idle wait that turned out to be an unbuffered 18 MB proof save through the WSL2 file bridge, 24 minutes) are fixed (ledger P20) 5 October 2026, live devnet with real transactions (bench-log "real transactions, the first non-empty shard proven and paid"): block 72704 shard 0, 29 transfers, 5,800 pgas, proven on PC 2 in 34 s, verified on the Mac in 0.297 s and paid 1.7623 IGN, 53 s after the chain block executed; of about 1,400 blocks in the 20-minute window 36 were proven (the one prover takes the newest shard assigned to it), so "every block" is not yet true; a second content shard (72803, all copies skipped) failed the native-execution veto on the exporter's block structure, fixed with fixtures the same day, the node side pending the 0.3.9 rollout 5 October 2026, evening (bench-log "proving v1"): the aggregated segment record, the chain rule and the unproven rule are implemented behind `proving_v1_activation_daa` (branch proving-v1, not on the devnet before 0.3.11); on the RTX 5090 a chain of 8 consecutive live blocks proved and aggregated by recursion in 135.6 s with the miner on the card (17 s a block, one proof of 1,272,909 bytes attesting all 8, verified in 0.04 s); the 3-node fast-time harness paid a segment record 1.0 s after submission and refused a late one after its deadline (21 checks); the devnet itself, with one prover, carried proofs for 2.4% of blocks over 30 minutes at a block-to-record latency p50 44 s, p99 52 s.

A shard at the provisional `S_p` is 60.8 M SP1 cycles on the prototype pgas table (9 cycles per pgas, 44 per EVM gas; the modexp entry about 100x its SP1 cost); on an RTX 5090 (4 October 2026 evening, job run-20261004-173115) it executed in 1.63 s and its compressed proof took 10.9 s, verified in 0.040 s, so the 32 GB card is inside the 20 s target with margin. Whether a 12 GB card proves it at all, and in what time, is the next measurement (an RTX 3060 and an RTX 5060 Ti 16 GB are on order). A per-shard time can be met by shrinking the shard, so the project does not use it as a pass mark 5 October 2026, evening (bench-log "proving v1", the S_p curve): measured on the RTX 5090 with SP1 6.8.1's GPU prover, the card to itself, 1-s nvidia-smi samples: an empty shard 13,874 MiB and 2.2 s; a full shard at the ADOPTED v1 budget (30,000 pgas, 4.7 M cycles) 20,434 MiB and 4.3 s; the full prototype shard (6.75 M pgas, 60 M cycles) 28,307 MiB and 10.8 s; beside the miner 15,670 and 30,039 MiB. No environment knob of SP1 moves the 13.9 GB floor and the GPU server has no options of its own, so on this build a 12 GB card proves nothing, a 16 GB card only empty shards, a 24 GB card the adopted full shard alone and beside the miner (22,210 MiB and 13.2 s, measured on the 32 GB card: the 5090's allocation pattern, not yet a run on a 24 GB card) and a 32 GB card the prototype shard beside the miner with 2.5 GB spare.

 ### M34. The shadow size N is a constant of the binary, so the one lever against the dataset-storing chip needs a fork to move
 "Your own Horizon lane says the reserve and the era draw buy nothing against a chip that stores the dataset, and that the only lever is the latency-shadow size N. N is 27 passes of a 256-instruction block, hard-coded in `V4_CLASS`. So when HBM4 doubles a chip's rate per stack in 2028, your answer is a hard fork, and a fork that retires the M5 Max at the first doubling. And now there is a shipping RandomX ASIC."
 
+Status: Relabelled (7 October 2026, morning, X36): the X9 in this row and in the litepaper paragraph is the chip Bitmain announced and withdrew before launch, its core claimed and never measured; the ladder's arithmetic against that core is unchanged.

Tests, the known-failed case first: a changed N today hashes another program under the same program id (a hard fork no pack line told apart); after, rung 0 is class v4 byte for byte, a rung above carries its pass count in the id, 8,999 bps in one window of seven does not move the step, a two-step jump is impossible, down never passes rung 0, an inadmissible rung is never entered. Stated in `site/litepaper.html`, Mining section ("The work that waits can grow").
 
 Answer: Correct on both counts, and the second was the sharper one. The X9 (Bitmain, about 1 MH/s at 2,472 W, approximate, github.com/monero-project/monero/issues/10270) is a shipped 3x per-joule edge over a desktop CPU on the best-known latency-bound random-program design, seven years after launch; it makes the k = 0.3 column of the chip model a product class rather than an attacker's claim, and the public headline is now the range 2.1x (k = 1) to 3.9x (k = 0.33) over the RTX 5090 at class v4, with the ladder taking the X9 bracket to about 2.8x by rung 2 and the Apple tier's to about 1.1x by rung 3. The ladder does not close the gap; it is the chain's only automatic answer, it moves at the pace of the cards that pay for it, and the honest card's watts remain the lever that moves every row (algorithm lane proposal 7). What the ladder gives up by design: a chip holding over 10 percent of weight can stall it, and the status quo it stalls is a rung the cards already run.

+Answer: The k about 0.33 column stays in the public range as the X9's claimed, unmeasured core: Bitmain's figures (1,000 KH/s at 2,472 W, 2.47 J/KH) were a pre-order sheet, never a benchmark, and the RandomX team's own reading (sech1, 25 January 2026) was "no, X9 is not an ASIC... Only 2x efficiency gap (hash/Joule) is not 'cracked'": a box of commodity Sophgo SG2044 server SoCs with an AES block and over sixty DRAM sticks, no tapeout, about 2x per joule over a tuned Zen 4 part and about 3x over a stock desktop CPU. It was withdrawn rather than face a RandomX re-tune of 1.5x or more. The lesson the public text now carries is that one: a maintained algorithm with a credible upgrade path held, which is what the latency ladder is for Igneum. Monero's hashrate shows no X9 fleet (about 6.1 GH/s before and after, approximate).

One event, no cause in the journal, the retry passed.

 | A stamp file at a nested path failed every checkout of /srv/builds/igneum (18:31 to 18:5x UTC, the shipper's 18:52 run) | a repo-kind crate keeps its `.build-remote-sha-<target>` and `target/` inside the crate dir; the checkout mode's clean-tree test only excused them at the tree root | the test is depth-agnostic and uses `--untracked-files=all` (a wholly untracked directory is otherwise collapsed to `?? dir/`); the self-test carries a nested stamp, a nested target dir and a stale `.git/index.lock`, which the mode now removes when no git runs there |
+| The attack rows lost scratch dirs to each other's builds (7 Oct 2026, 09:2x UK, hazard AP-H1 from the attack-pass lane) | checkout_tree's `git clean -fd` ran on the shared mirror before every build from any agent and took every untracked directory: `attack-f3/`, `attack-f1-venv/`, `tools/attack/*/target` | the clean spares the fixed prefixes and the globs in `.igneum-scratch-spare` (R4a), still without `-x` so `.git/info/exclude` applies; the clean-tree test asks `git clean -nd` with the same excludes instead of filtering the status list, so a spared dir no longer reads as "not clean"; the self-test carries a fixed-prefix dir at the root and nested, a declared dir, the spare file and an undeclared dir; `tools/ci/scratch-spare-check.sh` in the gate |

+organisation's deploy-key policy had to be switched to Enabled first). The sync's own test then still said "mirror": `ssh -T` to

+# The launch pack: gates and text, no protocol (mission item 10)
+
+7 October 2026, 10:1x to 11:xx UK, the launch-pack lane (branch `launch-pack`, worktree `igneum-wt-launch-pack`, from master b92a5fd4). Mission item 10 of `docs/analysis/mission/mission.md` 2.10, built from `past.md` sections 3 and 4, `future.md` section 8, `reinvent.md` 3.1 and 4.1, `docs/plans/testnet-go.md` and the litepaper. This is an operations document: `docs/plans` is not on the public export list, so it may name the owner; the text handed to the site lane in section 4 may not, and `tools/ci/launch-gates-check.mjs` greps it.
+
+the project lead's three decisions of this morning, written in everywhere below:
+
+| Decision | the project lead's word (7 October 2026, 10:1x UK) | Where it lands |
+|---|---|---|
+| The proving customer | A signed proving customer IS a mainnet gate: one signed customer paying for proofs at a published rate, or a signed letter of intent with a volume, before mainnet, not before the testnet | `testnet-go.md` LG-11; the journey's phase 4 gate loses "one rollup signs for testnet" (section 4, item E); ledger X13 status (section 4, item F) |
+| The certificates | APPROVED: Windows EV Authenticode and an Apple Developer organisation account, both under Igneum Labs LTD, executed the day the entity exists | LG-3; the runbook in section 2; the signing step in 2.4 |
+| The disclosure prize | YES, USD 50,000; payer Igneum Labs LTD; staged until the entity address exists on its documents and the project lead's publish word (`docs/plans/cryptanalysis.md` 3.3, branch `cryptanalysis`, 43d9700b) | LG-13; nothing public until the word |
+
+## 1. The gates
+
+The thirteen gate rows are in `docs/plans/testnet-go.md`, section "Launch gates", each with its check, its state today and its owner. The check that keeps them honest: `node tools/ci/launch-gates-check.mjs` fails when a row has no check, when a check names a repository path that does not exist, when the handoff text in section 4 carries a served-page pattern or an em dash, or when one of the eight regulatory sentences is missing or out of order. Its `--self-test` fires on each of those. Both run in `tools/ci/pre-push.sh`.
+
+What this lane built, and what each gate still needs:
+
+| Gate | Built here | Still owed, by whom |
+|---|---|---|
+| LG-1 income per tier | `tools/launch/income-tiers.json` (the measured rows, each with its source), `tools/launch/income-tiers.mjs` (the generator, `--check`), `tools/launch/income-tiers.test.mjs`, `docs/analysis/income-tiers.md` (public) | re-generate at the 0.4.0 cut from class v4 rates (the shipper); the RTX 4060 and Apple wall power, an Intel row (the fleet lane) |
+| LG-2, LG-6, LG-7, LG-9, LG-10, LG-12 the hash-origin report | `tools/observer/hash-origin.mjs` (the job: `--dry`, `--write`, `--post`, `--fixture`), its fixture and test; ran read-only on the live devnet tables today | the Devnet 2 observer with a table prefix (fleet lane); the fleet registry's key file (fleet lane); the systemd timer (build-server lane); the two X5 columns (the observer owner); the pool statement format (the pool lane) |
+| LG-3 signed installers | the runbook (section 2) and the signing-step specification (2.4) | the project lead: the entity's documents, the two enrolments (section 5); the shipper: the step |
+| LG-4 first-share time | the measurement specification (2.5) | the fleet lane: `tools/fleet/first-share-time.sh` |
+| LG-5 the text | the handoff block (section 4) | the site lane: land it, rebuild, deploy |
+| LG-11 the customer | the gate line and its check | the project lead: the signature; the execution engineer: the paid job |
+| LG-13 the prize | the gate line pointing at the staged text | the project lead: escrow, the address, the word |
+
+## 2. The certificate runbook
+
+Two enrolments, both in the entity's name, both the day Igneum Labs LTD exists on paper. Neither names the founder publicly: an Apple Developer ID certificate reads `Developer ID Application: Igneum Labs LTD (TEAMID)` and an EV Authenticode certificate reads the entity's registered name; the person who enrols is known to Apple and to the certificate authority, not to the public.
+
+### 2.1 Apple: the Developer Program as an organisation
+
+| Item | Value | Source |
+|---|---|---|
+| Provider | Apple Developer Program, organisation membership | https://developer.apple.com/programs/ (read 7 October 2026 by lane 5: USD 99 a year, notarisation included) |
+| Cost | USD 99 a year | the same page |
+| What the entity supplies | (1) a D-U-N-S number for Igneum Labs LTD at its registered address (free from Dun and Bradstreet; Apple has its own D-U-N-S lookup and request form; a new entity's number can take days to weeks to issue, approximate); (2) the legal entity name exactly as the DIFC registrar records it; (3) a person with legal authority to bind the entity (a director) who enrols with an Apple ID on an entity mailbox (for example `developer@igneum.network`) with two-factor on; (4) a website on a domain the entity controls (igneum.network); (5) a phone number Apple can call for verification | Apple's enrolment requirements for organisations, from memory, approximate; the exact list is on the enrolment page at the time |
+| What comes out | A Team ID; a `Developer ID Application` certificate (and a `Developer ID Installer` certificate if a .pkg is ever shipped); notarisation through `notarytool` with an app-specific password or an App Store Connect API key | Apple's notarisation documentation, from memory |
+| Where the key lives | In the login keychain of the Mac that runs `packaging/mac/build-dmg.sh`, exported once to an encrypted .p12 kept with the entity's records; never on igneum-build-1 (CLAUDE.md: the box holds no secret that signs releases) | this lane |
+| Time | Enrolment review by Apple: days, approximate; D-U-N-S first | from memory, approximate |
+
+### 2.2 Windows: an EV Authenticode certificate
+
+| Item | Value | Source |
+|---|---|---|
+| Provider | One of the public CAs that issue EV code-signing certificates: DigiCert, Sectigo, GlobalSign, SSL.com (the four this lane knows; from memory). The choice that matters: the CI runner must sign, so pick one whose private key lives in the CA's cloud HSM with a client for Windows (SSL.com eSigner with its CodeSignTool, DigiCert KeyLocker with `smctl`; Sectigo and GlobalSign have hardware-token and cloud options; from memory, approximate). Azure Trusted Signing was considered and set aside: its public-trust tier wants three years of verifiable organisation history (from memory, approximate), which a new DIFC entity cannot show | lane 5 (`reinvent.md` 3.1) for the SmartScreen facts; this lane for the provider notes |
+| Cost | USD 300 to 700 a year for EV, approximate, from memory of list prices; cloud signing may add a monthly fee or a per-signature count | approximate |
+| Why EV and not OV | Both are hardware-bound since the CA/B Forum's June 2023 rule (private keys in a FIPS 140-2 level 2 token or an HSM; from memory). EV used to grant SmartScreen reputation at once; SSL.com's page says Microsoft "moved away from automatic instant reputation" (`reinvent.md` 3.1, read 7 October 2026), so even EV may show the interstitial until the file earns reputation. the project lead chose EV; the download page states the two clicks until the 1,000-download mark either way | `reinvent.md` 3.1 |
+| What the entity supplies | (1) the DIFC certificate of incorporation or commercial licence showing the registered name and address; (2) proof the address is the one on the registrar's record; (3) a telephone number the CA can verify (a public directory listing, or a letter from the entity's accountant or lawyer when there is none); (4) the government ID of the person signing the subscriber agreement and a director's letter authorising that person; (5) the D-U-N-S listing from 2.1, which shortens the CA's organisation check | the EV code-signing guidelines' identity requirements, from memory, approximate; the CA's own checklist governs |
+| What comes out | A certificate in the CA's HSM (or a USB token posted to the registered address), a signing account for CI with a short-lived credential, and a timestamp URL | approximate |
+| Where the key lives | In the CA's HSM; the CI credential in the repository's GitHub secrets (rotatable); a USB token, if that route is taken, stays with the Mac and signs through `osslsigncode` with a PKCS#11 module; never on igneum-build-1 | this lane |
+| Time | Validation 1 to 5 business days after the documents, approximate | from memory |
+
+### 2.3 Mailboxes and records to create with the entity
+
+| Item | Why |
+|---|---|
+| `developer@igneum.network` (or the name the project lead picks) | The Apple ID of the organisation account and the CA's subscriber contact |
+| `security@igneum.network` | The disclosure address of the prize (`cryptanalysis.md` 3.3; the project lead's call on the name) |
+| The D-U-N-S number | Apple requires it; the CA uses it |
+| An encrypted record of the Team ID, the certificate serials, the expiry dates and the renewal month | Renewal is a calendar item the way a domain is |
+
+### 2.4 The signing step in the shipper's cut (specification; the shipper ae892a8b0f78fe31c implements)
+
+Today `packaging/mac/build-dmg.sh` signs ad hoc (`codesign -s -`), the app strips its own quarantine on start, and the Windows exes and installer are unsigned (`.github/workflows/windows.yml`, step "installer"). The step below adds signing where each binary is built and verification where the shipper already verifies, so `tools/ship-app.mjs` keeps its step list (`preflight bump inputs commit ci fetch dmg copy mirror manifest deploy verify console`) and gains checks inside `fetch`, `dmg` and `verify` rather than a new step.
+
+| Where | What changes | Check |
+|---|---|---|
+| `.github/workflows/windows.yml`, step "installer", before ISCC | Sign `igneum-app.exe`, `igneumd.exe`, `igneum-miner.exe`, the window host and the worker exes with `signtool sign /fd SHA256 /td SHA256 /tr <timestamp url>` through the CA's KSP (the cloud client logs in from two GitHub secrets: the account credential and the TOTP or API key the CA gives); then the Inno script's `SignTool=` directive signs the installer and its uninstaller with the same command. The secrets are absent on a fork or a pull request: the step then builds unsigned and marks the artefact `unsigned`, and the shipper refuses it (next row) | `signtool verify /pa /v dist\*.exe` in the same job prints the signer and the timestamp; the smoke-run step reads it |
+| `tools/ship-app.mjs`, `fetch` | After `packaging/windows/fetch-ci-artifacts.sh`, run `osslsigncode verify <installer>` on the Mac (Homebrew `osslsigncode`): the signer CN must equal `Igneum Labs LTD`, the digest SHA-256, a timestamp present; an unsigned or wrongly signed installer fails the step with the line | the step's own exit |
+| `packaging/mac/build-dmg.sh` | Replace `codesign -s - -f` with `codesign --force --options runtime --timestamp --sign "Developer ID Application: Igneum Labs LTD (TEAMID)"` on every binary under `Contents/Resources/bin` and `Contents/MacOS`, then the app bundle (with an entitlements file only if a binary needs one; none is known today); `xcrun notarytool submit <zip of the app> --keychain-profile igneum-notary --wait` must print `Accepted`; `xcrun stapler staple` the app, then build the DMG, then `xcrun stapler staple` the DMG; remove the app's own quarantine strip (it exists for the ad-hoc case only) | `spctl --assess --type execute -vv <app>` prints `accepted` and `source=Notarized Developer ID`; `codesign --verify --deep --strict <app>` exits 0 |
+| `packaging/ota/publish-manifest.sh` and the manifest | Two fields per platform file: `signed_by` (the signer CN as verified) and `notarized` (true or false); `publish-manifest.sh` refuses `--public` when either is missing | `tools/ship-app.mjs --check` and the manifest's signature check already run; add the field check there |
+| `tools/ship-app.mjs`, `verify` | Besides size and sha256: download the live installer and run `osslsigncode verify`; mount the live DMG and run `spctl --assess`; both results must match the manifest fields | the step's own exit |
+| The download page (`site/miner.html`, the site lane) and the Discord release post (`tools/community/discord-hooks.mjs release`) | Show "Signed by Igneum Labs LTD" and the sha256 only when the manifest says so; keep the "what your antivirus may say" line (`reinvent.md` 3.1) and the exact SmartScreen text and two clicks until the 1,000-download mark | `tools/ci/launch-gates-check.mjs` greps nothing here; the site's own build grep runs |
+| `tools/ci/signed-release-check.sh` (new, with the implementation) | A manifest in `dl/public/` without `signed_by` on every file fails; `--self-test` with a manifest missing the field | in `tools/ci/pre-push.sh` |
+
+Order of work for the shipper once the certificates exist: the Mac side first (one machine, one keychain, one release), then the CI side (the cloud-signing client in the runner), then the manifest fields, then the download page. Until the certificates exist nothing in this table runs, and the 0.4.0 cut ships unsigned with the page saying so (`funding.md` section 2, the client audit row: "the one-click app ships at testnet unaudited and says so on the download page").
+
+### 2.5 The first-share time, measured per release (specification; the fleet lane builds `tools/fleet/first-share-time.sh`)
+
+`reinvent.md` 3.1: the time from download to the first accepted share has never been measured end to end on a fresh machine. The measurement is a Devnet 2 gate step, one run per platform per release:
+
+| Step | What | Where |
+|---|---|---|
+| 1 | A fresh Windows 11 VM (Hyper-V on the RTX 5090 Windows rig, or a rented Windows box) and a fresh macOS VM (Tart or UTM on the Mac) from clean images; no Igneum files on them | the fleet lane's box library (`tools/fleet/lib/`) for the rented case; a Mac job for the macOS case |
+| 2 | The script downloads the release from the public URL, runs the installer (Windows) or opens the DMG and copies the app (macOS), starts the app with the Devnet 2 network setting, and reads the app's own log for three stamps: install done, node synced, dataset built, then the first accepted share or block | the app's log lines are the clock; the script never reads a reported rate |
+| 3 | One line into the gate log: `FIRST-SHARE <windows or mac> download=<s> sync=<s> dataset=<s> share=<s> version=<v>` | `~/Desktop/fleet/devnet2-gate-<stamp>.log`, the same file `devnet2-gate.sh` writes |
+| 4 | The numbers go to `/evidence` as a row per release ("download to first share, fresh Windows 11: N min M s; fresh macOS: N min M s"), with the date and the version | the site lane |
+| Gate | Under 10 minutes in 9 of 10 fresh Windows installs (mission item 6), measured across releases | the /evidence rows |
+
+## 3. The hash-origin report: what it is and how it runs
+
+`tools/observer/hash-origin.mjs`. Once a day, from the observer's tables, who found the blocks. It reads `live_blocks` (24 h: vote key, payout address, colour), `live_state` (the node's hash-rate estimate), `miner_logs` (the vote keys the project's intake-reporting workers logged) and, with `--fleet-keys <file>` or `IGNEUM_FLEET_KEYS_FILE`, the fleet registry's key list. It writes, only with `--write`, its own two tables (`hash_origin_days`: one row per key per day for the 30-day dust and independence counts; `hash_origin_reports`: the day's report as posted) and the jsonb column `hash_origin` on `live_state` for the site. With `--post` it posts to #numbers through `tools/community/discord-hooks.mjs`'s poster (its guard refuses any post with a machine id, a path, an IP or a 32-hex token; key `hash-origin:<date>`, so a day posts once).
+
+| Command | What |
+|---|---|
+| `node tools/observer/hash-origin.mjs --fixture tools/observer/fixtures/hash-origin-day.json` | The fabricated day; no database |
+| `node tools/observer/hash-origin.mjs --dry [--go 2026-10-20]` | The live tables, read-only (ran today) |
+| `node tools/observer/hash-origin.mjs --dry --prefix dn2_` | The Devnet 2 observer's tables, once that observer runs with `LIVE_TABLE_PREFIX=dn2_` |
+| `node tools/observer/hash-origin.mjs --write --post --live --go <date>` | The daily run on the box |
+| `node --test tools/observer/hash-origin.test.mjs` | The known-finished and known-failed days; in `tools/ci/pre-push.sh` |
+
+Today's read-only reading on the live devnet (7 October 2026, 11:xx UK), and what it means (the consequences rule):
+
+| Line | Reading | What it means, and what is done about it |
+|---|---|---|
+| Keys | 113 with a block, 95 above the dust line, ten largest 45.0 percent | The devnet runs the project's machines with several identities each (ledger-decisions.md decision 13 moves the default to one key per machine), so 113 keys is not 113 miners; the independent count is the X5 definition and its two owed columns |
+| Fleet | 36 keys, 38.4 percent "fleet"; 77 keys, 61.6 percent "outside" | False: the rented boxes do not upload identity lines, so the job cannot see them as the project's. The fleet registry's key file fixes it (`IGNEUM_FLEET_KEYS_FILE`); until the fleet lane exports it, LG-7 is void and the report says so by its numbers |
+| Pools | 13 shared payout addresses (68.4 percent); attested pools 0 | A shared payout is a pool or one machine with several identities; the job counts a pool only when attested (the project's own, or an operator's signed key list), so no devnet machine is mistaken for an outside pool and LG-9 cannot pass on a multi-key machine |
+| Network | 0.76 GH/s, no yesterday | The step line needs two days of its own table; the first run with `--write` starts the series |
+
+The runbook for the box (build-server lane; `infra/build-server/hands/` holds the observer's units):
+
+| Item | Value |
+|---|---|
+| Unit | `igneum-hash-origin.service` (oneshot) and `igneum-hash-origin.timer`, `OnCalendar=*-*-* 08:30:00 UTC` (before the 09:00 UK digest), `Persistent=true` so a missed day runs at boot |
+| Command | `node tools/observer/hash-origin.mjs --write --post --live --go <go date>` from the box's checkout, as the observer user |
+| Environment | `EnvironmentFile=/srv/observer/env` (DATABASE_URL) and `/srv/discord-hooks/env` (the webhooks, already on the box by the 6 October exception); `IGNEUM_PROJECT_POOLS=<pool-0 payout address>`; `IGNEUM_KNOWN_POOLS=` (empty until a statement exists); `IGNEUM_FLEET_KEYS_FILE=/srv/observer/fleet-keys.txt` (written by the fleet lane's export, one 64-hex key per line, mode 600) |
+| Devnet 2 | The same unit with `LIVE_TABLE_PREFIX=dn2_` once the Devnet 2 observer runs; seven days of posts before step 10 is LG-2 |
+| 90 days | The timer runs for ever; LG-12 counts the first 90 days from the go in `hash_origin_reports` |
+| Gate | The unit is trusted after one run that posted and one run with the database string removed that failed loudly (the watcher rule) |
+
+## 4. The text, handed to the site lane
+
+Everything between the two markers is for the site lane (a4b202cabca2d95c0 deploys). It is written to the copy law and `tools/ci/launch-gates-check.mjs` greps it against `site/forbidden-strings.txt` and `tools/ci/forbidden-strings.txt`. The site lane lands it in `site/index.html`, `site/litepaper.html`, `site/journey.json`, rebuilds (`node site/build.mjs`) and pushes; the ledger owner takes item F into `docs/fud-ledger.md` (`tools/ledger-page.mjs` renders it).
+
+<!-- handoff:start -->
+
+### A. The front page: the three wants lead (`site/index.html`, the hero and the first block under it)
+
+The miners' own words asked for three things (twenty posts and launch texts, 2018 to 2026, `docs/analysis/mission/past.md` section 2: hardware that keeps its value, 10 of 20; income above electricity that does not fall off a cliff, 6; a fair supply, 4). Nobody asked for finality, a DAG or proofs. The front page answers the three in order; finality moves to page two. The h1 stays as it is. Under it, three cards, each with one heading and three to four short lines:
+
+**1. Your card stays a card.**
+The hash is a new random program every hour over a dataset the chain draws from its own state. No scheduled fork, no release a team must ship. The chip model and its number are published with every era on /evidence. When you stop, the card still games.
+
+**2. Income with no cliff.**
+100 IGN a block, falling 2.9 percent a month. No halving day. Then 1 percent of supply a year, for ever. A block pays its miner whether or not anyone buys a proof that day. What each card mines, and what its electricity costs, is one table: the income page.
+
+**3. A fair supply.**
+No premine. No fund, no foundation, no fee to any team. Nobody holds a coin before block one. The founders mine from genesis with disclosed addresses and the same software as everyone else. The first 90 days ramp from 10 percent, so the launch weeks are worth less to a private farm.
+
+Under the three cards, one line and a link: "Blocks are final by miners alone, with no stake and no other chain. How, on page two." (the link is the litepaper's "Speed and finality" section).
+
+The income page: render `docs/analysis/income-tiers.md` as `/income` (or link the public mirror's copy) and link it from card 2 and from `/miner`. The page is generated; the site lane does not edit its numbers.
+
+### B. Page two: finality (`site/litepaper.html`, "Speed and finality")
+
+No change to the section's text. The change is placement: the front page's hero no longer carries a finality claim; the "Igneum at a glance" block keeps its one finality line and links down to the section. The explorer and the wallet keep their finality state words.
+
+### C. The block sentence (`site/litepaper.html`, "Three income streams, one balance", directly under the table)
+
+"A block pays its miner whether or not anyone buys a proof that day. The lottery pays 80 percent of every block from emission; proving is the second income, never the only one. Every useful-work chain on record dropped its miners the day the work stopped paying; Igneum's miners are paid for the block first."
+
+### D. The eight sentences (`site/litepaper.html`, a new short section "What the chain is, in law" at the end of Economics, under the label "Not legal advice; counsel is engaged")
+
+Each sentence is `docs/analysis/mission/future.md` 8.3, verified against the file on 7 October 2026 and re-worded to the copy law where the file's own line was a note; the number in brackets is the file's. The heading sentence: "Not legal advice; counsel is engaged. These are the facts of the design that the rules of each region turn on; nothing here is a promotion of anything."
+
+1. No issuer, no offeror, no sale. Every coin is created automatically as a reward for the maintenance of the distributed ledger or the validation of transactions, and in no other way. (8.3 sentence 1; the quoted words are MiCA Article 4(3)(b)'s, verbatim, as the file asks)
+2. The sustainability indicators of Delegated Regulation 2025/422 (energy in kWh a year from the network's hash rate and the measured microjoules per hash, intensity per transaction, the regional mix when it is known) are published by the project every era, so a service provider in the EU can list the coin without asking. (8.3 sentence 2)
+3. No financial promotion. No price, no "buy", no "invest", no return language anywhere. The earnings screen shows hash and IGN, never a currency. (8.3 sentence 3; the income page shows electricity in dollars as a cost, never the coin's price, which is this sentence kept)
+4. The reference pool never holds a member's balance. Payouts come straight from the coinbase split; the pool coordinates, it does not keep custody. (8.3 sentence 4)
+5. The job market settles peer to peer on the chain. There is no operator account and no dollar leg in the protocol: the dollar figure is a quote, the settlement is IGN. (8.3 sentence 5)
+6. The software is published under an open licence by a company that holds no coins by right and runs no service the chain's consensus depends on. There is no dev fund. (8.3 sentence 6; the file's line reads "runs no service the chain depends on"; "consensus" is added because the company does run seeds, a public RPC and a log intake, none of which consensus needs; counsel reads both)
+7. Mining may be restricted where you are; you are responsible for checking. The miner asks your region at first run and refuses the regions where mining is banned (the file's list on 7 October 2026: ten regions of Russia and Moscow from 15 August 2026, and China). (8.3 sentence 7)
+8. No privileged key. No key can mint, pause or upgrade the chain; the only way a rule changes is miners signalling for it, and nothing requires them to. (8.3 sentence 8)
+
+### E. The journey (`site/journey.json`)
+
+| Phase | Today | Change |
+|---|---|---|
+| phase-4, gate | "Finality design passes external review and one rollup signs for testnet" | "Finality design passes external review" |
+| phase-5, gate | "1,000 independent miners run 30 days and rollup proofs are delivered on time" | unchanged |
+| phase-6 (mainnet), when | "After the testnet has passed its gate: 1,000 independent miners for 30 days and rollup proofs on time" | "After the testnet has passed its gate (1,000 independent miners for 30 days, rollup proofs on time) and one proving customer has signed: a customer paying for proofs at a published rate, or a letter of intent with a volume" |
+
+### F. The ledger rows (`docs/fud-ledger.md`; ids provisional, the ledger owner renumbers on merge)
+
+**X13 (existing), status update.** Decided (7 October 2026, 10:1x UK, by the owner): a signed proving customer, paying for proofs at a published rate or a letter of intent with a volume, is a MAINNET gate (testnet-go.md LG-11). The phase 4 gate drops "one rollup signs for testnet". The pilot progression in the answer stands: a signature opens mainnet, repeat purchases and a second unrelated customer are the evidence after it.
+
+**X37. Your installer is a warning screen.**
+"Windows says 'Windows protected your PC' and the Mac refuses to open it. A miner's first screen on your chain is an operating-system warning, and you call that one click."
+Status: Open, certificates approved (7 October 2026): an EV Authenticode certificate and an Apple Developer organisation account, both in the entity's name, enrolled the day the entity exists; the signing step is specified for the release tool and runs from the first signed cut. Until then the download page shows the exact warning text and the two clicks.
+Answer: True today. The DMG is signed ad hoc and the Windows installer is unsigned. SmartScreen warns on any file without reputation and reputation is use, so the interstitial may outlive the signature by some downloads; the page says so. The measured time from download to the first share on a fresh machine is published per release.
+Evidence: testnet-go.md LG-3 and LG-4; launch-pack.md section 2.
+
+**X38. Nobody will know whose hash the launch is.**
+"On launch week your own rented cards will be most of the hash, and the chart will look like Nervos in 2020 or Iron Fish in 2023: a step nobody can explain."
+Status: Open, the report built (7 October 2026): a daily hash-origin report from the observer, posted in public for the first 90 days and on the staging chain for seven days before the go: keys with a block, keys above dust, the project's own fleet share, attested pools, the ten largest keys, and any 2x step in the estimate with the keys that carry it.
+Answer: Right that the first weeks are the project's own cards plus whoever shows up, and that a chart alone cannot tell them apart. The report names the project's share every day, from the project's own key list, so the step is explained the day it happens. What it cannot do yet: count independent miners (the autonomous-system and fingerprint columns are owed), or tell a pool from a machine with several keys without the pool's own signed statement.
+Evidence: testnet-go.md LG-2, LG-6, LG-7, LG-9, LG-12; tools/observer/hash-origin.mjs.
+
+**E23. You will show a number that makes someone buy a card.**
+"Every GPU chain's launch page had an earnings number, and every one was wrong inside six months."
+Status: Stated (7 October 2026): the income page shows IGN a day per measured card at three network sizes, electricity a day at three tariffs, and the electricity cost of one mined IGN; no coin price appears, every rate is a measurement with its source, and the page says what each tier should expect from the record of other chains.
+Answer: Agreed, and the record is the argument: income halves within 60 to 120 days of a peak and falls under power within 6 to 18 months on every chain in the sample. The page shows the arithmetic the miner can redo with the live network figure, and nothing else.
+Evidence: docs/analysis/income-tiers.md; testnet-go.md LG-1.
+
+**L10. The eight sentences.**
+"You say 'not legal advice' and then write eight sentences of it."
+Status: Open, counsel engaged (the owner, 6 October 2026); the eight sentences are the design facts the rules turn on, each cited to its regime in the research file, and they go to counsel with the litepaper before mainnet.
+Answer: The sentences state what the design does (no issuer, no custody in the pool, no dollar leg, no privileged key, the region refusal) and what the project publishes (the energy indicators); they do not say what any law concludes. Counsel decides the wording for each region.
+Evidence: docs/analysis/mission/future.md section 8; testnet-go.md LG-5.

+| 8 | The three tariffs | DECIDED (the coordinator for the project lead, 7 October 2026, 11:xx UK): electricity tariffs per kWh, never a coin price; the triple is USD 0.05 (cheap industrial), 0.10 (US retail) and 0.25 (UK retail at today's rate), and the table was regenerated on it. Nothing left here | none |

 Standing rulings of the same hour: "We dont want to penalise holders" (dormant-coin rent and anything that takes from a balance or taxes inactivity is refused for ever); vote-or-burn is implemented only if 95 percent or more of the mining community would respect it (the weigh-up lane decides between the burn and the signing bonus).

+
+| # | Decision | the project lead's word | What it sets |
+|---|---|---|---|
+| 1 | Emission schedule | Approved | The testnet genesis carries `EmissionSchedule::TESTNET_1`: 100 IGN a block at 1 bps, a monthly glide with a two-year half-life, a 90-day ramp from 10 percent, a tail of 1 percent of supply a year from the month the glide first pays under it (about year 11.4). No hard cap; the public sentence is the one in docs/analysis/tail-emission.md. Ledger E22 moves to Decided. The devnet keeps `CURRENT`. |
+| 2 | Signing bonus at the testnet genesis, no burn | Approved | `signing_bonus_activation_daa` = 0 and `signing_bonus_bps` = 1,000 in the testnet genesis; the unsigned tenth to the proving pool; the vote-or-burn code leaves the tree before the testnet code is public. |
+| 3 | The latency ladder | Approved | The six rungs (27, 35, 53, 88, 173, 267 passes), rungs 0 to 2 admissible, rung 3 re-measured on a quiet core before genesis, 4 and 5 inadmissible until verifiers allow; every step by 90 percent in each of seven windows, never unconditional; `latency_ladder_activation_daa` = 0 on the testnet at rung 0. |
+| 4 | Cryptanalysis | Approved, "make sure they find ZERO flaws, also cut costs if possible" | The engagement runs at the low point (about USD 80,000) unless a quote forces more; an internal attack pass precedes it so the firms find nothing new; every finding is fixed before the testnet go. The contracting entity and the prize are still the project lead's to confirm. |
+| 5 | Re-cut the testnet genesis | Approved | One cut with 18 decimals, `TESTNET_1`, and the switches on from genesis: proof verification, the leave item, the signing bonus, finality v3, the ladder at rung 0. Nothing live is touched; the go checklist decides the date. |

+the project lead, 11:2x UK: "free reign to check the copy everywhere to make it sound as human, friendly and GPU community focused."
+Done as part of the redesign integration, on every served page. The register: one miner talking to another, second
+person where it fits, no corporate voice, no hype, no scare. Every fact and number is exactly as our files state it;
+the ledger's stated sentences (tools/ci/ledger-text-check.mjs), the regulatory lines and "not an offer to sell
+anything" are verbatim. Copy law kept: no em dashes, no two-beat antithesis, no aphorisms, short sentences, numbers in
+tables, no orphan word on a line (tools/ci/site-orphan-check.mjs at 390 px).
+
+## The twenty biggest changes
+
+| # | Page | Before | After |
+|---|---|---|---|
+| 1 | Home, hero | A proof-of-work chain for graphics cards, whose miners prove the blocks. | Your GPU has more to give. (the package's line, kept) + You already own the card. Igneum gives it a job worth doing: mine the block, prove it, watch it lock. One click installs the node, the miner and the prover. |
+| 2 | Home, principles | (none; the home page was the scene and three facts) | Graphics cards only / The miners are the provers / No premine, no stake / Every claim has a status, one line each under the hero |
+| 3 | Home, live panel | (the scene with no heading) | Follow the work. See the chain grow. + "Every square is a real block, read from one node every 2 s. Nothing here is a replay." |
+| 4 | Home, reasons | (none) | Three reasons to power on: A program that never holds still / Work you can see / One click, and it mines, each in plain words with the measured limit named |
+| 4a | Home, reasons (7 October 2026, the launch pack) | Three reasons to power on | Three things, in order: Your card stays a card / Income with no cliff / A fair supply, the three asks of twenty miner launch posts (docs/plans/launch-pack.md section 4 A), in the same three cards; the income card carries no emission number until the genesis re-cut, and the line under the grid points at the litepaper's finality section |
+| 5 | Home, economics | (on the litepaper only) | Made for the people running the hardware. Every block pays the card that found it and the cards that prove it. The protocol carves out nothing for a team, a foundation or a fund. |
+| 6 | Home, CTA band | (none) | Give your GPU something to do. Download Ember, watch the devnet, and tell us what breaks. The people on the Discord run cards like yours. |
+| 7 | Miner, hero | Install. Start. The card mines. (kept) | The miner built around your card. Your rate, your watts, what it costs a day at your price, and the chain drawn live with your own blocks ringed. |
+| 8 | Miner, downloads | Three buttons in a list | A platform card: Windows, macOS, Linux / HiveOS, each with one sentence of what to expect ("A Mac mines on its GPU at about a fifth of a flagship card and proves on its CPU, slowly."), the signed file, its version, size and sha256 |
+| 9 | Miner, steps | (none) | Check your card / Install the official build / Press Start, then tell us, with the seed-phrase warning in the second person: "Keep it to yourself. This site never asks for it." |
+| 10 | Miner, FAQ | (none) | Six questions miners ask first: does the website mine on my GPU, does my card mine and prove, is the devnet paying real money, is there a fee, can I run it on a rig or in a pool, where do the numbers come from |
+| 11 | Miner, Linux tab | Install on a Hive rig | For the rig people. One tarball, the miner and the node inside, the same signed manifest as the desktop apps. |
+| 12 | Wallet, hero | Your coins. Final means final. (kept) | ... it checks every finality certificate itself with the node's own code. No confirmation counts, no trusting the node. (verifies -> checks) |
+| 13 | Wallet, MetaMask | One click adds the Igneum network with its chain id and RPC. | + a link to the same values on this site, so a Windows or Linux miner has a path today |
+| 14 | Journey (new page) | Journey linked to the litepaper's roadmap table | Six phases from the specification to a fair launch. Each closes at its gate, a measurement published whether it passes or fails, so there is no date to slip. + the log, newest first, with a filter |
+| 15 | Claims (new page) | Footer link into the litepaper | What Igneum does not claim. Every limit we know of, written down here before anyone else writes it. (the body is the litepaper's section, unchanged) |
+| 16 | RandomX (new page) | Footer link into the litepaper | Random-program mining is the idea Igneum borrowed. Here is what changed when it was rebuilt for graphics cards, and what RandomX's seven years say and do not say about this chain. |
+| 17 | Explorer | Paste a block hash, a transaction hash, a chain block number or an address. | ... or click any row. |
+| 18 | Faucet | Paste an address. The faucet sends 10 testnet IGN and shows the transaction hash. | ... and shows you the transaction hash. Once per address per day, once per connection per day. No account, no sign-in, nothing to install. |
+| 19 | Live devnet | Every block has a story. Follow the connections. | Every block has a story. Follow the connections, and find your own. |
+| 20 | 404 | The pages below are where most readers want to go | The pages below are where most people want to go; the miner page added as the first card |
+
+## What was deliberately left alone
+
+- The litepaper's text: every section is our text as it stood on master (the X9 relabelling, the X31 to X36 corrections, the chip model), under the package's reading layout. The reading tone is already plain; the technical sections stay precise.
+- The ledger, the evidence table, the bench log and the bench table: generated from docs/, restyled only.
+- The app page's feature copy (already in the register) and every screenshot caption, which names the machine, the version and the time.
+- The chip-model paragraph on the home page and the miner page: the Counter ASIC lane's current text, word for word.
+- The downloads notices: "Public testnet: not yet open; the devnet build is here for people who want to look." and the rest, verbatim (ledger rows X2, X31, E5).
+
+## Removed from the package, not served
+
+The package's own copy where it made claims our files do not: "Hardware becomes the network" (kept as "Your card becomes the network", an illustration caption), its sample wallet balance and sample address, its "Simulated" app window, its "Sample feed" labels, its historical benchmark examples, its "optional 1% software dev fee" phrasing where it drifted from the measured 1.146 percent and the one-flag rule, and its launch-date language.

+## Launch gates (mission item 10, 7 October 2026, 10:1x UK)
+
+Added by the launch-pack lane (branch `launch-pack`) from `docs/analysis/mission/mission.md` 2.10, with the owner's three decisions of the same morning written in: a signed proving customer is a MAINNET gate (not a testnet gate); the code-signing certificates are approved (Windows EV Authenticode and an Apple Developer organisation account, both under Igneum Labs LTD, executed the day the entity exists); the USD 50,000 disclosure prize is YES, staged until the entity address exists and the owner gives the publish word (`docs/plans/cryptanalysis.md` 3.3 on branch `cryptanalysis`). The runbooks, the signing-step specification and the text handed to the site lane are in `docs/plans/launch-pack.md`. Every row has its check; `node tools/ci/launch-gates-check.mjs` (in `tools/ci/pre-push.sh`) fails when a row loses it or names a script that is not there. "When" says which go the gate holds: T = before the testnet go (steps 1 to 11 above), C = a community gate after the go with no date (`docs/analysis/mission/reinvent.md` 4.1), M = before the mainnet go.
+
+| Gate | What must be true | Check | When | State at 10:1x UK, 7 October 2026 | Who |
+|---|---|---|---|---|---|
+| LG-1 Per-tier income at three tariffs | `docs/analysis/income-tiers.md` is published before the testnet: one 8, 12, 16, 24 or 32 GB card, a rig and a pool user, IGN a day at three network sizes from the measured bench rows and `EmissionSchedule::TESTNET_1`, electricity a day and per mined IGN at USD 0.05, 0.10 and 0.25 a kWh (cheap industrial, US retail, UK retail; decided 7 October 2026), each tier with what it means and what is being done (the consequences rule) | `node tools/launch/income-tiers.mjs --check` (the page equals its inputs) and `node --test tools/launch/income-tiers.test.mjs` (the schedule arithmetic: 6,912 IGN a day for 100 MH/s on 100 GH/s at the launch rate, day 1 at 10 percent, one month step at 2^(-1/24)); the page is in the public export and passes `tools/ci/identity-check.sh` | T | DONE on the branch from the 6 October rented-card rows (ten-field class). OWED: re-generate at the testnet cut from class v4 rates; the RTX 4060 and Apple wall power; an Intel row | launch-pack lane, then whoever cuts 0.4.0 |
+| LG-2 Hash-origin report on Devnet 2 for seven days before the go | The daily report (keys with a block, keys above dust, attested pools and shared payouts, the project fleet's share, the ten largest keys, the network step) posts from the Devnet 2 observer's tables on seven consecutive days before step 10 | `node tools/observer/hash-origin.mjs --prefix dn2_ --dry` prints a report; seven consecutive `hash-origin:<date>` keys in the poster's state for that prefix; `node --test tools/observer/hash-origin.test.mjs` (a known-finished day and a known-failed day) | T | The job exists and ran read-only on the live devnet tables today (113 keys, 0.76 GH/s). OWED: a Devnet 2 observer writing `dn2_live_*` (fleet lane), the fleet key file from the fleet registry, the systemd timer on the box (`docs/plans/launch-pack.md` section 3) | launch-pack lane (job), fleet lane (observer, key file), build-server lane (timer) |
+| LG-3 Signed and notarised installers | The 0.4.0 DMG is signed with a Developer ID certificate of Igneum Labs LTD, notarised and stapled, and opens on a fresh macOS machine with no Privacy and Security visit; the Windows installer and every exe inside it carry an EV Authenticode signature of Igneum Labs LTD with a timestamp | `spctl --assess --type execute -vv <app>` prints `accepted` and `source=Notarized Developer ID`; `osslsigncode verify <installer>` (or `signtool verify /pa /v`) prints the signer `Igneum Labs LTD` and a timestamp; the shipper's `verify` step writes both into the manifest (`signed_by`, `notarized`) and the download page shows the signer and the sha256 (`docs/plans/launch-pack.md` section 2.4) | T | NOT DONE: certificates approved 7 October; the entity's documents and the two enrolments are the owner's (section 2, items for the owner); the signing step is a specification for the shipper (`docs/plans/launch-pack.md` 2.4) | the owner (enrolments), the shipper (the step) |
+| LG-4 First-share time measured per release | Every release's Devnet 2 gate measures download to first accepted share on a fresh Windows 11 VM and a fresh macOS VM, as three timed steps (download and install, sync, dataset build), and the numbers are published on /evidence; the mission's bar is under 10 minutes in 9 of 10 fresh Windows installs | the gate log carries `FIRST-SHARE <platform> download=<s> sync=<s> dataset=<s> share=<s>` for both platforms (`docs/plans/launch-pack.md` 2.5 is the specification of the script that writes it, tools/fleet/first-share-time.sh, OWED: until it exists this row is OPEN); the /evidence row equals the log line | T | OWED: specification written, script not built; no fresh-machine time has been measured end to end (`docs/analysis/mission/reinvent.md` 3.1) | fleet lane with the shipper |
+| LG-5 The launch text on the site | The front page leads with the three wants (hardware that stays useful, income without a cliff, a fair supply) and finality moves to page two; the litepaper carries "A block pays its miner whether or not anyone buys a proof that day"; the eight regulatory sentences of `docs/analysis/mission/future.md` 8.3 are on the litepaper under "not legal advice; counsel is engaged"; the journey's phase 4 gate no longer says a rollup signs for the testnet | `node tools/ci/launch-gates-check.mjs` (the handoff block exists, carries no served-page pattern, no em dash, the eight sentences numbered in order); after the site lane lands it: `grep -c "whether or not anyone buys a proof" site/litepaper.html` is 1 and `grep -c "automatically created as a reward" site/litepaper.html` is 1 | T | Text handed over in `docs/plans/launch-pack.md` section 4 (branch `launch-pack`); nothing on the live site changed | site lane |
+| LG-6 First 100 keys | 100 distinct vote keys with a blue block in the last 24 h | the hash-origin report's `gates.first_100_keys` (`node tools/observer/hash-origin.mjs --dry --json`) | C | Devnet reading today: 113 keys with a block, most of them the project's multi-identity machines; the testnet counts from its own go | the report |
+| LG-7 First block from a card the project does not own | A blue block whose vote key is in neither the intake-reporting workers' identity lines nor the fleet registry's key file | the report's `gates.first_block_outside_fleet`, valid only with `IGNEUM_FLEET_KEYS_FILE` loaded (without the file the devnet reads its own rented boxes as outside: today 77 "outside" keys, which is the missing file, not outsiders); the post needs the owner's permission (reinvent.md 4.1 G-C2) | C | Void until the fleet key file exists (OWED, fleet lane) | the report, the fleet lane |

+| LG-9 First pool not run by the project | An attested outside pool (its operator published the signed member-key list X5 asks for) with 10 percent of blue blocks for 7 consecutive days | the report's `gates.first_outside_pool` with the pool's payout address in `IGNEUM_KNOWN_POOLS`; a shared payout address nobody attested never passes it (the test's third case) | C | No attested outside pool; the devnet's 13 shared payout addresses are multi-identity machines and the project's pool-0 | the report, the pool lane (the statement format) |
+| LG-10 First 1,000 independent keys (X5) | N_ind of at least 1,000 over 30 days, independent in autonomous system, machine fingerprint and pool attestation, top-10 share of window weight under 50 percent (`docs/plans/ledger-decisions.md` section 3) | the report's `independent` block once the observer stores the autonomous system per announcing address and the fingerprint per key; until then the report prints the keys above dust as an upper bound and never passes the gate (`gates.first_1000_independent` is false by construction) | C, and the gate of mainnet genesis | The two observer columns are OWED (app-owner item, ledger-decisions.md section 3); today's upper bound on the devnet is 95 | the observer owner |
+| LG-11 A signed proving customer | One customer paying for proofs at a published rate, or a signed letter of intent with a volume, before mainnet (the owner, 7 October 2026: a mainnet gate, not a testnet gate; the weight of the Devnet 2 gate: mainnet does not open without it) | the contract or the letter in the entity's records, a redacted copy linked from `docs/evidence.md`, the rate on the site; for the paying case the job market's payout contract shows a paid job for that customer; `grep -c "rollup signs for testnet" site/journey.json` is 0 after the handoff lands | M | NOT DONE: Taiko is named as the first customer and nothing is signed; the brief and the pilot progression are ledger X13 | the owner (the signature), the execution engineer (the paid job) |
+| LG-12 Hash origin daily for 90 days | The report posts every day for the first 90 days from the go, with no gap | `SELECT count(*) FROM hash_origin_reports WHERE day >= '<go date>'` reaches 90 with consecutive days; the timer's journal on the box shows a run per day | C | The job and its `--go <date>` flag exist; the timer is OWED (section 3 of the pack) | build-server lane (timer), the report |
+| LG-13 The disclosure prize | USD 50,000 for a reproduced break of the published hash class, paid in fiat by Igneum Labs LTD, announced only when escrowed and only when the entity's registered address exists on its documents and the owner gives the publish word | `docs/plans/funding.md` rule 3 (escrow before announcement); the staged text in docs/plans/cryptanalysis.md 3.3 on branch `cryptanalysis` (43d9700b, not on master yet); until the word, `grep -ci "50,000" site/*.html` is 0 | M (the announcement may come earlier, on the word) | APPROVED by the owner at 09:5x UK on 7 October 2026; STAGED; nothing public mentions it | the owner (escrow, the word), the cryptanalysis lane (the announcement) |

+# The build boxes (infra/build-server)
+
+Three Hetzner dedicated servers in Falkenstein run everything the Mac must not: builds, test suites, benchmarks, CPU proving, the
+devnet hands and the observer. The Mac keeps macOS binaries, the DMG and Metal tests (CLAUDE.md, "Running agents on this Mac").
+
+## No mining on any Hetzner box, ever
+
+the project lead's rule through main, 7 October 2026: Hetzner's policies forbid crypto mining. The boxes run nodes, builds, tests, benchmarks and
+CPU proving only. The pool's fast-time network runs its miners on rented GPU pods (tools/fleet), never on a box; a box may run the
+network's nodes. The capacity layer refuses a job that would start `igneum-miner mine` or a GPU worker (capacity/run.sh), and no
+hands unit carries a miner. A node started with `--enable-unsynced-mining` is a node flag, not a miner; nothing feeds it blocks here.
+
+## The boxes and the kind map
+
+| Box | Host file on the Mac | Takes | Never |
+|---|---|---|---|
+| igneum-build-1 (188.40.146.49, AX162-1-LTD) | `~/.config/igneum/build-server` | release gates (`--priority gate`), builds and cross-builds, checks, the GPU workers' host side, the devnet hands (node 1, the observer node, the observer), the Devnet 2 seed, the CI runner, the dashboard feed | suites and benches once box 2 exists |
+| igneum-build-2 (AX162-1, on order) | `~/.config/igneum/build-server-2` | suites (`cargo test`), benches (`cargo bench`), the attack rows (`--box 2`) | gates, hands |
+| igneum-build-3 (AX102-1, on order) | `~/.config/igneum/build-server-3` | proving and aggregation CPU work (proving/igneum-prove builds and suites), the second prover's shadow runner, the pool's fast-time NETWORK (nodes only, `--box 3`) | miners of any kind |
+
+`tools/build-remote.sh` routes by class (lib.sh `bs_route`): suite and bench to box 2, the proving crate to box 3, everything else
+to box 1; `--box N` overrides; a class whose box has no host file yet falls back to box 1 and says so. `--priority gate` always runs
+on box 1. Each box has its own mirrors, slots, locks and JSONL log under /srv; `run-from-mac.sh --box N <ip>` provisions a box and
+writes its host file; the dashboard collector reads every box it is told about.
+
+## Files
+
+| File | What |
+|---|---|
+| `provision.sh` | the box itself: install mode (rescue system, Ubuntu 24.04, RAID 1, no swap) and provision mode (user build, toolchains, the pin, sccache, zig, CUDA headers, docker, Caddy, mirrors, slots, sshd, ufw) |
+| `run-from-mac.sh` | ships provision.sh, writes the host file, wires the `build` remotes and pushes every branch |
+| `lib.sh`, `remote-run.sh` | the Mac and box halves of a remote run: sync, checkout, slots, scheduling classes, the JSONL line |
+| `hands/` | the devnet hands' units, the mover and the restart read-backs |
+| `capacity/` | the capacity layer (the box-work lane's): background jobs under the build slots, never a miner |
+| `repro/`, `night/`, `prover/`, `runner/`, `workers/` | other lanes' pieces that live on the boxes |
+
+Plan, numbers and the gotchas: docs/plans/build-server.md; the hands: docs/plans/hands-on-build-1.md.

 <p>Machine: the same Apple M5 Max. No CUDA toolchain exists on it, so nothing below is an NVIDIA measurement. Added <code>--export-pack &lt;dir&gt;</code> to <code>proto-metal/main.swift</code>. It writes, per seed, the CUDA kernel (<code>kernel.cu</code>), C headers (<code>program.h</code>, <code>vectors.h</code>), JSON twins, and the Metal source, into <code>proto-cuda/packs/&lt;seed&gt;/</code>. Vectors: 3 warps (base nonces 0, 4096, 1000000), 96 x 64-bit outputs from the CPU interpreter, plus dataset words 0..15 and word [MASK]. The exporter runs the Metal kernel for the same warps and refuses to write unless all 96 match.</p>

 <p>Model: 1 day steps, 86,400 Poisson blocks/day, 1,000 Pareto honest keys (top key 17%), perfect retarget, every block blue, no latency, no VRF noise. Seed 7, seed 11 agrees. Rule: weight = 30-day sum of counted blocks, counted = min(actual, 2 x yesterday + f). Lock at 2/3 of total. Floors f in {1, 10, 100, 1000}. A: weight tracks hashrate at steady state (corr 1.00000); full weight from zero history on day 41 (f=1) to 32 (f=1000). B: 60% renter on one key takes 59.9% of rewards on day 1, crosses 1/3 of weight on day 20 to 26, 50% on day 27 to 34, never 2/3. 75% renter reaches 2/3 on day 29 to 34, day 27 with the cap removed. C: splitting defeats the cap. 10,000 fresh keys at f=1 move the 50% crossing from day 34 to 27 (no-cap figure 26); at f=10 they match no-cap exactly. The 30-day trickle buys 2 more days for 11.6% of the network. D: honest doubling is under-weighted 28 to 31 days; old miners lock alone for 20 to 23 days. E: 30% churn leaves 71% live, lock never lost. Threshold is 1/3: 35% stalls 1 day, 50% stalls 10 to 11 days. Active-24h total removes every stall. F: 51% patient owner holds 51.0% weight from day 45, vetoes from day 7 to 20, never locks alone. 67% owner locks alone from day 34 to 44. Recommend: f=1, cap 2x, window 30 (the window is the defence, the cap is worth 1 to 8 days), total = all keys with weight in the window. Details in sim/results.md.</p>

 <p>Machine: the same Apple M5 Max. Added <code>--fuzz</code>, <code>--edge</code>, <code>--stats</code>, <code>--determinism</code>, <code>--memcheck</code>, <code>--inline-dataset</code> to <code>proto-metal/main.swift</code>. Full tables and commands in <code>proto-metal/TESTS.md</code>. Fuzz: 10,200 random programs (200 + 10,000, cold compiles 13.6 to 48.5 ms), 4 random full-range warps each, dataset drawn from 64 MiB / 256 MiB / 1 GiB: 40,800 warps, 1,305,600 hashes, 0 mismatches, 0 compile failures, 0 static mask failures, generator contract (rotl 1..31, mask in {1,2,4,8,16}, src != dst) held on every instruction. 196 s for the 10,000 run. Edge: 14 hand-built cases (rotr by register 0 / 32 / -32 / 31 / 63, rotl 1 and 31, mulhi max operands, shfl masks 1..16, loads at index 0 and MASK via in-range and out-of-range registers, add/sub/mul/mad wraparound, zero loads, 64 loads) with operand values proven by a traced interpreter: 14/14 PASS, 128/128 lanes each. rotl by 0 (never generated) agreed too, recorded as informational only. Stats (3 seeds, 2^20 nonces each): bit frequency max deviation 2.90 sigma over 192 bit positions; avalanche 16,000 flips mean 31.99 to 32.04 (expect 32), std 3.98 to 4.01 (expect 4), every output bit flips with probability 0.490 to 0.508; chi-square on four 16-bit windows all within 2.3 sigma; 0 duplicates. Looks uniform. Not a security proof. Determinism: 5 runs and 3 compiles (one forced cold, 30 ms) of 2^20 hashes gave fingerprint 933787e8cfefccb7 every time; dataset fill deterministic (0b1a77899ee60493 twice) and 4,096 sampled words incl. 0 and MASK match the CPU closed form. Memcheck: every <code>dataset[</code> in the MSL is <code>dataset[rN &amp; MASK]</code> (13/13 at 3 sizes), CUDA twin 13/13 plus one guarded fill write; 4 MiB run with nonces up to 0xffffffff completed and 4 wrapping warps matched the CPU; 416/416 load indices exceeded MASK before masking. Bench re-run after the changes: igneum-genesis 44.56 Mhash/s, epoch1 47.74 Mhash/s at 1 GiB, PASS 3/3 warps each (within 2 percent of the first-run table). <code>--export-pack igneum-genesis</code> re-run is byte-identical to the existing pack. SHORTCUT MEASURED: <code>--inline-dataset</code> replaces every load with the six-op closed form ds_elem and never reads memory: 4,888 Mhash/s wall (6,274 GPU time) vs 44.6 honest at 1 GiB, about 110x, and about 9x the cache-resident honest rate. With a closed-form dataset the hash is not memory-hard; an expensive dataset derivation is required, not optional. Not demonstrated: cryptographic strength, weak-program frequency and rejection, NVIDIA/AMD bit-exactness (CUDA run still pending), CPU verify gate with an expensive dataset element. Next three tests for the cryptographer are listed in TESTS.md section 8.</p>

 <p>Result: the same hourly program, generated on the Apple M5 Max, compiled by Apple's Metal and NVIDIA's CUDA, produced identical hashes on both vendors. Vendor independence of the lottery program is demonstrated for one program; igneum-hourly and the dataset sweep are the next runs. The ratio 5090 to M5 Max is about 5x on hashes and on random loads per second, approximate, consistent with a memory-bound program (random-access bound, not bandwidth bound: the 5090 writes the dataset at 1638 GB/s but hashes at 95 GB/s of useful 4-byte loads). Caveat unchanged: the prototype dataset is closed-form and not yet memory-hard (see TESTS.md), so these are prototype numbers, not mining numbers.</p>

 <p>Second program igneum-hourly (128 loads per hash): 96/96 vectors PASS, 185.3 Mhash/s at 1 GiB, 23.7 G random loads/s.</p>
 <p>Reading: the 5090 carries 96 MiB of L2. At 4 and 64 MiB the dataset sits inside it and the program runs about 5.8x faster than at 1 GiB. Past the L2 the rate settles at about 23.7 G random loads/s for both programs regardless of loads per hash (104 vs 128 loads gives 228 vs 185 Mhash/s, proportional), so the program is random-access bound once the dataset exceeds on-chip cache. Each 4-byte random load moves a 32-byte sector, so DRAM traffic is roughly 760 GB/s, approximate, against a quoted peak near 1.8 TB/s for this card. Design consequence: the dataset must stay well above any plausible on-chip cache, which the 2 GB genesis size and the growth schedule provide; a chip would need gigabytes of on-chip memory to escape the random-access limit. Still prototype numbers: dataset derivation remains closed-form until the 256 MB cache construction lands.</p>

 <p>Model: 30-s slots, Poisson(30) blocks/slot, 1,000 Pareto honest keys in 3 regions (45/35/20), 2-s inter-region delay (0.5 and 5 swept), uptime 97% (99.5% for pools over 1%), warm 30-day start for B to G. Seed 7, seed 11 agrees on B and E. Run time 5 min. Details in sim/results_v2.md. Rule: weight = flat 30-day blue blocks, dust 100, checkpoint per 30 blocks, lock at 2/3 of ACTIVE (participation over 240 checkpoints) vs TOTAL weight. A: weight = hashrate (corr 1.00000), full weight day 30, all keys over dust by day 20, lock median 2.5 s / p99 4.6 s at 2 s delay, 14 s max at 5 s, 0 stalls in 60 days except 17 at genesis. B: share(t) = (t/30) x a/(1+a) holds to 0.04 points; 1/3 crossed at day 20.0 / 15.0 / 12.5 / 11.1 and 2/3 at never / 30.0 / 25.0 / 22.2 for a = 1 / 2 / 4 / 9; dust hands a 9x renter 1.3 extra points. C: silent set that keeps mining: active recovers in 0 / 13 / 20 / 29 / 38 min at 34 / 40 / 45 / 50 / 55%; total never (silent weight never ages out). D: churn: active 2 min (35%) and 31 min (50%); total 41 h and 10.1 days. E: active FAILS the partition test: 50/50 honest split, no attacker, both sides lock after 60 min (30 with DAA retarget), 60/40 after 121 min; first-lock time = presence x (1 - 1.5 s)/s slots, confirmed. Total: 0 conflicts in every honest partition. 34% attacker breaks every variant at 50/50 (67% per side). F: delayed eclipse of a 20% pool is harmless (participation 0 after 2 h, back in 2 h, 0 conflicts); a 34% attacker poisoning that pool finalises a private fork in 49 min under active, never under total. Floor hybrid: active denominator never below 0.85 x total (lock needs 56.7% of total) gives 0 conflicts in every partition and eclipse, recovers in 0 / 13 min at 34 / 40% silent and 2 min at 35% churn; costs 4.1 days at 50% churn and liveness ends near 42% silent. Floor 0.80 does not stop the eclipse (54% &gt; 53.3%). Recommend: active/cert + floor 0.85, presence 240, dust 100, quorum 2/3, grace at least 3x worst delay. Not modelled: real GHOSTDAG merge and post-heal fork choice, DAA lag, VRF aggregators, certificate revocation.</p>

 <p>Machine: the same Apple M5 Max (one performance core for the CPU figures). Construction, every table and the commands are in <code>proto-metal/MEMHARD.md</code>. Default dataset is now memory-hard; <code>--closed-form</code> keeps the original for comparison. Construction: 256 MiB cache = 2^22 lines of 64 B in 2^16 chains of 64 ChaCha12 blocks with feed-forward (in_j = prev ^ (sigma || K[8] || seg || j || tag)); item t = 16 words, 8 rounds of (seed-parameterised ARX-multiply mixer, read cache line s[0] &amp; (2^22-1), xor) plus a final mixer; dataset[w] = item(w &gt;&gt; 4)[w &amp; 15]. Hash kernel unchanged. Cache fill: 2.0 ms GPU (0.6 to 2.1 across runs), 185 ms one CPU core (Swift), 162 ms C++ host reference. Dataset build 1 GiB: 20.6 ms GPU (29.4 first in process), 814 M items/s, 6.5 G cache-line reads/s. GPU cache == CPU cache on all 2^26 words every run (FNV-1a 64 48c4f5bf24166b2e for day 2026-10-03). Shortcut ratio, seed igneum-genesis, 1 GiB: honest 45.2 Mhash/s in both constructions. Inline kernel (never reads the dataset): closed form 5,014 Mhash/s (111x FASTER than honest); memory-hard 9.49 Mhash/s (0.21 of honest, 4.8x SLOWER). At a 256 MiB dataset: honest 94.8, inline 9.48 (0.10). CPU verify per 32-lane warp (holds only the cache, derives every word on demand, 32 lanes interleaved): 0.649 / 0.631 / 0.701 ms for igneum-genesis, /epoch1, /epoch2 (104, 104, 112 loads; 3,328 to 3,584 items); 0.801 ms igneum-second-seed (104 loads); 1.205 ms igneum-second-seed/epoch1 (144 loads, 4,608 items). Cold single warps 1.16 to 2.11 ms. Closed form was 0.017 ms. 10 ms GATE MET, margin about 8x steady. Levers (implemented, measured, OFF by default; default generator unchanged): (a) --load-weight 17: 72 to 80 loads/hash, CPU 0.457 to 0.512 ms/warp, GPU 55.0 to 73.4 Mhash/s. (b) --wide-frac 50 (warp-coalesced 128 B loads): CPU 0.233 to 0.489 ms/warp, GPU 56.1 to 135.2 Mhash/s and useful bandwidth up to 56 GB/s, so (b) erodes the random-access bound. (a)+(b): CPU 0.223 to 0.276, GPU 106 to 139. Recommendation: no lever; (a) is the fallback if a slower verifier ever threatens the gate; (b) not recommended. Tests re-run on the new dataset: fuzz 200/200 (800 warps, 25,600 hashes, 0 mismatches, CPU interpreter 1.23 s), edge 14/14, determinism PASS (fingerprint 62a4f0eb018df273), memcheck PASS, stats PASS (3 seeds, no obvious bias). 3 warps x 3 seeds bit-exact in the bench run. CUDA: new pack proto-cuda/packs/igneum-genesis-mh (kernel.cu with cache-fill and build kernels, memhard.h shared by device and host, vectors incl. cache head/last/FNV and 64 sampled words). host.cu handles both modes; old packs unchanged (closed-form export re-run is byte-identical in kernel.cu and program.metal). clang emulation (emu/emu.sh igneum-genesis-mh): cache check PASS (all words, FNV == Mac), dataset self-test PASS at 1 GiB, 3/3 vectors standalone and 2/2 in batch at 2 warps/block. RTX 5090 and AMD runs of this pack PENDING; no NVIDIA figure for the memory-hard dataset exists. Not demonstrated: cross-vendor results for the new dataset; the shortcut ratio on a discrete GPU; time-memory trade-offs between the two measured points; cryptographic strength of the mixer and the chained cache; distinct-lines-per-hash census.</p>

 <p>Machine: Apple M5 Max (18 CPU cores), 64 GB, macOS 26.6.2. Toolchain: Homebrew rust 1.69.0 was too old (repo needs 1.91.0), so rustup 1.29.1 was installed non-interactively and gives rustc 1.99.0 and cargo 1.99.0; protobuf 36.2 added via <code>brew install protobuf</code> (protoc was missing); Apple clang 14.0.3 already present. Nothing else was needed. Source: <code>vendor/rusty-kaspa</code> at commit <code>01b532e8b553523216471682649693af92f0fd16</code> (v2.1.0, 2026-09-22). <code>cargo build --release --bin kaspad</code>: 2 min 36 s cold, binary 35,405,104 bytes (34 MB), 131 compiler warnings, zero errors. Devnet: three <code>kaspad --devnet --nodnsseed --disable-upnp --enable-unsynced-mining --yes --loglevel=info</code> nodes, separate <code>--appdir</code>, P2P 16611/16621/16631, gRPC 16610/16620/16630, nodes 2 and 3 <code>--connect</code> to node 1 (node 3 to node 2 never came up because both started at once, so the topology was a star through node 1). Network params: 10 BPS (100 ms blocks), GHOSTDAG k 124, merge depth 36,000 blocks, finality depth 432,000, pruning depth 1,080,000, DAA window 661 samples x 40 blocks, genesis bits 0x1e21bc1c (about 248,663 hashes per block). Miner: kaspad ships none, so a 150-line CPU miner on <code>kaspa-pow::State</code> (real kHeavyHash, 16 threads, 300 ms template refresh) submitted to node 1 only: 27.2 MH/s sustained, 5,718 blocks in 180 s, 0 rejected. Blocks per second over the 180 s run: 31.76 on all three nodes (1,691 to 7,409 blocks each). Two phases: 56 to 62 blocks/s while difficulty sat at genesis (first 6,000 blocks, min window 150 samples), then the DAA raised difficulty to 1.12 M at block 6,018 and the rate fell to 14 to 15 blocks/s, still converging toward the 10 BPS target when the run ended. Propagation: block counts, DAA scores and sink hash were identical on all three nodes at 18 of 19 ten-second samples; the one miss was node 2 trailing by a single block for one sample. Tips stayed at 1 because a single serial miner never produced parallel blocks, so GHOSTDAG k was not exercised; a second miner is the next step for that.

 <p>Reading: the memory-hard construction is now bit-exact across Apple Metal, NVIDIA CUDA and the CPU reference, cache and dataset included. Hash rate is unchanged from the closed-form dataset on both vendors, as expected, since the hash kernel only loads; what changed is that computing items on the fly is now slower than loading them (4.8x slower measured on Apple, not yet measured on NVIDIA). Still unmeasured: the inline shortcut ratio on NVIDIA, and AMD on any dataset.</p>

 <p>Machine: Apple M5 Max (18 logical cores), rustc 1.69.0, GMP 6.3.0 via rug 1.19. Source <code>proto-vdf/</code>, details in <code>proto-vdf/README.md</code>. Single core sequential squaring unless stated. Rates: class group 1024-bit prime discriminant (production choice, chiavdf construction, NUDUPL/NUCOMP ported from vendor/chiavdf) 163,000 sq/s; class group 2048-bit 83,500 sq/s; RSA-2048 trusted-setup stand-in (public trapdoor, timing only) 1,257,000 sq/s. T for 10 min / 60 min on this core: class 1024: 98.0 M / 588 M; class 2048: 50.1 M / 301 M; RSA-2048: 754 M / 4.53 G. Full 10-min runs: RSA T=756,516,411 eval 607.1 s (1,246,000 sq/s), prove 9.0 s on 12 threads (71.2 s on 1), verify 0.88 ms, proof 512 bytes. Class 1024 T=97,126,043 eval 585.4 s (165,900 sq/s, the RSA run sharing the chip ended midway), prove 9.1 s on 12 threads (56.8 s on 1), verify 4.47 ms, proof 516 bytes. Prover costs 12 to 13 percent of eval single-threaded (12-bit digits, at most 65,536 checkpoints, 17 MB) and parallelises over residue classes; verify is two 256-bit exponentiations, 4.5 ms class 1024 (12.6 ms including deriving D from the checkpoint hash), 1.4 ms RSA. Seed pipeline: epoch_seed(checkpoint) -&gt; (seed, proof) and verify_epoch_seed; the same checkpoint hash gave the same seed and identical proof bytes in two separate processes at T=1,000,000; wrong checkpoint, flipped seed bit and T+1 all rejected. Attacker speed: delay must only exceed the 2 s publish-or-lose window; margin is 300x at the epoch and 1,800x at the era, so a 2x (or 10x, or 100x) faster evaluator leaves grinding impossible. Requirement: the checkpoint hash must commit to full block hashes incl. nonce. Grinding model (3,600 blocks/epoch, advantage uniform 0 to 15%, keep top quartile, one block burned per withheld candidate), gain per epoch in blocks, no delay vs with delay: s=0.1 +0.40 vs 0; s=0.2 +1.66 vs 0; s=0.3 +3.62 (+0.32%, 13.5:1 on burned blocks) vs 0; s=0.4 +6.06 vs 0. Monte Carlo over 2,000,000 epochs agrees to 0.03 blocks. Correctness: NUDUPL, NUCOMP and the Lehmer partial xgcd agree with Cohen 5.4.7 / plain duplication / plain-division xgcd on 15,000 random cases; block prover equals the naive O(T) prover at T = 37, 5,000 and 100,000 in both groups; 216 associativity triples; 3 tamper cases rejected per size. Recommend: class group 1024-bit D from the checkpoint hash, epoch T = 600 x r_ref and era T = 3,600 x r_ref with r_ref the fastest honest single-core rate measured on the devnet (98 M and 588 M on this Mac), fixed at genesis, 20 min lead time for the epoch seed and 2 h for the era draw, 256-bit Fiat-Shamir prime. Open: external review of classgroup.rs against chiavdf, reference core choice, fallback rule for a node without the seed at epoch start, carry D in the proof.</p>

 <p>Machine: Apple M5 Max, one performance core, rustc 1.99.0 (rustup), release build with LTO. Crate at <code>igneum-pow/</code> (seed, generator, memhard, verify, emit; CLI <code>bench</code>, <code>export</code>, <code>hash</code>), standard library only, serde_json as a dev-dependency for the pack tests. Agreement with the Swift through <code>proto-cuda/packs/</code>: program.json instruction by instruction for igneum-genesis, igneum-genesis-mh and igneum-hourly (3 x 64 match); mixer rot/mul/rc match; cache head, last line and FNV-1a 64 <code>48c4f5bf24166b2e</code> match; dataset head, <code>[MASK]</code> and 64 sampled words match in all three packs; hash vectors 96/96 for igneum-genesis-mh (memory-hard) and 96/96 each for the two closed-form packs. 23 tests, all pass. Emitted sources: kernel.cu, program.metal, kernel.cl and program.h byte-identical for all three packs, memhard.h and memhard.metal byte-identical for igneum-genesis-mh; <code>igneum-pow export</code> then <code>diff -r</code> against the packs differs only in the provenance string of vectors.json/vectors.h. Found: <code>proto-cuda/packs/igneum-genesis-mh/program.json</code> is not valid JSON (main.swift line 1291 writes <code>jhex(cacheLineMask)</code> inside the <code>"item"</code> string). The Rust emitter writes the mask bare and the test normalises that line; fix pending in the Swift. Cache fill, 256 MiB on one core: 175 to 181 ms in Rust (5 runs) against 184.5 to 190.6 ms Swift and 161.5 ms C++ host reference. CPU verify per 32-lane warp, avg of 20, 1 GiB dataset: igneum-genesis 0.441 ms (Swift 0.649), /epoch1 0.411 (0.631), /epoch2 0.488 (0.701), igneum-second-seed 0.482 (0.801), igneum-second-seed/epoch1 at 144 loads and 4,608 items 0.579 (1.205). Cold single warps 0.41 to 0.87 ms (Swift 1.16 to 2.11). Closed form 0.002 ms (Swift 0.017). Reading: Rust is 1.4x to 2.1x faster than the Swift verifier per warp with the same algorithm (register-major lanes, 32-lane interleaved item derivation); 10 ms gate margin about 17x steady, 11x on the worst cold warp. Cache fill is within 5 percent of the Swift and 10 percent slower than clang C++. API for the fork: <code>Epoch::memory_hard(seed, day)</code> once per epoch (fills the cache), then <code>epoch.hash(nonce)</code>, <code>epoch.hash_warp(base)</code>, <code>epoch.verify_block(nonce, target)</code>; <code>emit::export_pack(&amp;epoch, day, source)</code> for miner programs. <code>seed::seed_words_from_bytes</code> is the boundary for the VDF output. Not done: no GPU run from Rust; the 256-bit target mapping stays in the fork; the seed is still a string.</p>

 <p>Machine: the same Apple M5 Max. New: <code>proto-opencl/host.c</code> (C99, OpenCL 1.2 API), <code>kernel.cl</code> in every pack from <code>--export-pack</code> (same emitter, OpenCL C dialect; memory-hard core emitted in three dialects), <code>WAVEFRONT.md</code>, CPU emulator with a 32- or 64-wide sub-group. The AMD rig has not arrived; no AMD compiler or device has touched this code. Exchange rule: <code>sub_group_shuffle_xor</code> only when the device lists <code>cl_khr_subgroup_shuffle</code>, the work-group is exactly 32 and the queried sub-group size for a 32-item work-group is exactly 32; otherwise a <code>__local</code> memory exchange with one barrier per exchange (two alternating buffers). Wave64 hardware (GCN, CDNA, RDNA in wave64) therefore takes the local-memory path and the hash never depends on the wave width. Apple OpenCL 1.2 runtime, Apple M5 Max (40 CUs, OpenCL C 1.2, no sub-group extension, local-memory path): cache check PASS (all 2^26 words, FNV-1a 64 48c4f5bf24166b2e = Mac), dataset self-test PASS, 96/96 vectors standalone and in batch for igneum-genesis-mh; also 96/96 at <code>--exchange local --group-warps 2</code> and <code>--group-warps 4</code>; closed-form packs igneum-genesis 96/96 and igneum-hourly 96/96. Apple OpenCL hash rate (wall time; Apple's event timestamps are unusable), pack igneum-genesis-mh, 1 GiB, 5 x 2^24: 45.03 Mhash/s, 18.73 GB/s useful (repeat run 44.58). igneum-genesis 45.17, igneum-hourly 36.33 (128 loads). Metal on the same chip: 45.2. This is Apple's deprecated OpenCL on the M5 Max, NOT an AMD number. Apple OpenCL sweep (3 batches): 4 MiB 573.7 Mhash/s, 64 MiB 178.9, 256 MiB 94.3, 512 MiB 68.8, 1024 MiB 45.0 (Metal sweep shape reproduced). pocl 7.2 CPU device (OpenCL 3.0, LLVM 23, Khronos ICD loader, <code>brew install pocl</code>, needs SDKROOT): <code>--exchange auto</code> and <code>--exchange subgroup</code> built with <code>-cl-std=CL3.0 -D IGNEUM_EXCHANGE=1</code> and ran the real <code>sub_group_shuffle_xor</code> text: cache FNV = Mac, 96/96 PASS. pocl's <code>clGetKernelSubGroupInfoKHR</code> returns CL_INVALID_OPERATION, so the new probe kernel (<code>igneum_probe_subgroup</code>, reports get_sub_group_size() 32) decided; <code>--exchange local</code> also 96/96. CPU emulator (<code>proto-opencl/emu</code>, kernel.cl compiled as C++, 1 GiB dataset built on 256 host threads): 7 configurations all PASS with the identical batch fingerprint f99fb375b3abeaf5 over 2^13 outputs: exchange 0 with work-group 32/sub-group 32, 64/64, 32/64; exchange 1 (sub-group shuffles) with 32/32, 32/64, 64/64 (wave64 carrying two 32-lane units in one shuffle domain), 64/32. Cross-implementation fingerprint at <code>--batch-log2 13</code>, base nonce 0, igneum-genesis-mh: Apple OpenCL f99fb375b3abeaf5, pocl sub-group f99fb375b3abeaf5, pocl local f99fb375b3abeaf5, emulator f99fb375b3abeaf5 (all 7). At 2^24 Apple OpenCL prints 98af644e993239e2 (reference for the AMD run). proto-cuda emulator re-run after the header changes (program.h, vectors.h, memhard.h now C99-safe): PASS. Not demonstrated: any AMD compile or run, any AMD hash rate, the cost of the local-memory exchange on AMD, whether RDNA compiles igneum_hash as wave32 or wave64. Next: run the seven commands in <code>proto-opencl/README.md</code> on the AMD rig and paste the logs.</p>

Release build of <code>kaspad</code> and <code>igneum-miner</code>; the kHeavyHash stub engine (default feature set); <code>cargo check -p kaspad --features igneum-pow</code> also builds. Network: three <code>kaspad --devnet --nodnsseed --disable-upnp --enable-unsynced-mining</code> nodes, P2P 26611/26621/26631, gRPC 26610/26620/26630, nodes 2 and 3 <code>--connect</code> to node 1 and node 3 also to node 2; network name <code>igneum-devnet</code>, k 18, merge depth 3,600 blocks, DAA 661 samples x 4 blocks, genesis bits 0x1e020000 (2^23 expected hashes per block). Miners: three <code>igneum-miner mine</code> processes, 6 threads each, one per node, 960 s, each with its own vote-key label: 2.21 MH/s each (6.63 MH/s total), found 253 + 284 + 270 = 807 blocks, 0 rejected. Blocks per second: 0.84 on all three nodes over the 901.9 s watch window (755 blocks each); expected 0.79 from hash rate over genesis difficulty, then the DAA lowered difficulty from 4,194,304 to 3,444,348 after its 600-block minimum window (block 600 to 711), still converging to 1.00 when the run ended. Propagation: block count, DAA score and sink hash identical on all three nodes at 90 of 90 ten-second samples; 1.11 parents and 1.11 mergeset per block on average, tips stayed at 1 (three serial CPU miners rarely collide). vote_key_hash: <code>igneum-miner inspect 40</code> read the same 40 selected-chain blocks from all three nodes over gRPC and found the header's vote_key_hash identical on every node for 40 of 40 blocks, with the three miners' distinct hashes (17 + 17 + 6 blocks) all present, so the field round-trips through the template RPC, submit, p2p relay and the header hash. Emission: 80/20 exact on 39 of 39 single-payee coinbases (the 40th merged two blues, three outputs, pool share still 0.2000); at DAA 806 the payload subsidy was 317,767,704 units (launch ramp day 0, 10.03%), split 254,213,284 to the miner and 63,553,320 to the OP_RETURN <code>igneum-proving-pool-v0</code> output. Unit tests, release profile: kaspa-consensus-core igneum 8 pass (subsidy table, ramp, split, cap), params window test 1 pass, kaspa-pow 5 pass (stub) and 6 pass with <code>--features igneum-pow</code> (engine smoke, one 256 MiB cache, 0.39 s), kaspa-consensus coinbase 8 pass. Per-second subsidy, 8 decimals: 3,168,808,781 units (31.68808781 coins) for years 0 to 2, 1,584,404,390 for years 2 to 4, 792,202,195 for years 4 to 6, 1 unit in period 31, 0 from period 32; ramp day 0 is 316,880,878; the sum is under the 4,000,000,000-coin cap by less than 100 coins. Not done: the devnet ran on the kHeavyHash stub, not the lottery engine (the miner has no igneum-pow path yet and the lane hash does not absorb the header); no VDF seed, no finality, no prover payout; 8 versus 18 decimals open (docs/fork-divergence.md).</p>

Interim day seed "igneum-day/" || day_le64 (day = timestamp_ms / 86,400,000); epoch seed = the 32 bytes of the epoch block hash (genesis for epoch 0). 8 bound vectors in <code>igneum-pow/README.md</code>; 29 crate tests pass; the 288 pack vectors and the pack files are unchanged, <code>program_bound.metal</code>, <code>kernel_bound.cu</code> and <code>kernel_bound.cl</code> are new pack files.

Epoch change crossed live at DAA 3,600: new seed 76c39fcf..., 128-load program compiled by the worker in 129 ms (first program 6.5 ms), no rejected blocks across the change. Rate through the worker: 32.4 MH/s inside jobs, 28.2 MH/s wall, against 45.2 MH/s raw bench (<code>igneum-bench</code> 2^22 x 4 batches): the gap is the read-back and CPU scan per dispatch, one command buffer per dispatch, and the template round trip per job. Early in the run one job found about 45 sibling blocks of one template; the miner now submits one block per job. Overnight devnet (started 19:07 UTC): genesis bits 0x1d100000 = 2^28 expected hashes per block, sized for RTX 5090 229 + M5 Max 45 + gfx1036 4 = 278 MH/s (1.04 blocks/s); genesis hash edc4fa84...fb07; epoch 0 program 136 loads/hash compiled in 69.5 ms on Metal; node 1 alone (&lt;listen address&gt;/26611, <code>caffeinate -dims</code>, logs /tmp/igneum-devnet/node1.log) with the Metal worker (<code>/tmp/igneum-devnet/metal-worker.log</code>): 31 blocks in 273 s = 0.11 blocks/s at 31.1 MH/s, as expected for 2^28 until the RTX 5090 machine joins. Worker implementations, all bit-exact with <code>igneum-pow hash-bound</code> for a 96-nonce job across the 2^32 lane boundary (nonces 4294967264 to 4294967359, prehash ab x 32, devnet seeds): Metal (M5 Max GPU), OpenCL (<code>proto-opencl/host.c --serve</code>, Apple OpenCL 1.2 on the M5 Max, local-memory exchange, <code>--vendor</code> device filter added), CUDA (<code>proto-cuda/host.cu --serve</code> with the pack's <code>kernel_bound.cu</code>, through the clang emulation shim: bench PASS on the Rust-exported devnet pack, serve job bit-exact, seed-mismatch error exercised). CUDA and OpenCL are built ahead of time per pack; the Windows launcher re-exports and rebuilds at each epoch or day change (miner exit 42). <code>igneum-miner.exe</code> cross-compiled for x86_64-pc-windows-gnu with Homebrew mingw-w64 (9.4 MB; no rocksdb in the miner's closure). Not done: no NVIDIA or AMD run of the bound kernels yet (the Windows package <code>igneum-mine-test.zip</code> is the next step); NVRTC and runtime OpenCL rebuilds inside the workers; the block level for pruning proofs on a lane-only pow value; 8 vs 18 decimals; the VDF seeds and finality.</p>

 <p>Machine: Apple M5 Max, load average 60 to 110 (three other agents building), rustc 1.99.0, Homebrew mingw-w64 (gcc 16.2.0), Homebrew llvm (libclang). Worktree <code>vendor/igneum-node-win</code>, branch <code>windows-node</code> at <code>352495f6</code> (the rename commit <code>d62708a8</code> plus one miner change: <code>watch</code> prints <code>blue=</code> and <code>synced=</code> after <code>sink=</code>). Cross-compile: <code>cargo build --release -j 6 -p kaspad -p igneum-miner --features igneum-pow --target x86_64-pc-windows-gnu</code> at <code>nice -n 19</code>, 8 min 25 s from a clean target directory (recipe in <code>proto-cuda/windows-node/cross-build.sh</code>). <code>librocksdb-sys</code> (bindgen plus the bundled rocksdb and snappy C++) built with <code>LIBCLANG_PATH=/opt/homebrew/opt/llvm/lib</code>, <code>BINDGEN_EXTRA_CLANG_ARGS_x86_64_pc_windows_gnu="--target=x86_64-w64-mingw32 --sysroot=&lt;mingw sysroot&gt; -I&lt;mingw include&gt;"</code> and <code>CXX_x86_64_pc_windows_gnu=x86_64-w64-mingw32-g++</code>; zstd, lz4, bzip2, zlib, secp256k1 and mimalloc built with the mingw gcc. <code>igneumd.exe</code> 43,172,352 bytes, <code>igneum-miner.exe</code> 9,391,104 bytes. The exe imports <code>libstdc++-6.dll</code>: <code>-static-libstdc++</code> is ignored by the gcc driver rustc links with, and <code>-C link-arg=-static</code> (second full build, 8 min) does not cover a library rustc passes as <code>-Bdynamic</code>; the package ships <code>libstdc++-6.dll</code>, <code>libgcc_s_seh-1.dll</code> and <code>libwinpthread-1.dll</code> next to the exe (fix for next time: empty <code>CXXSTDLIB_x86_64_pc_windows_gnu</code> plus <code>-Wl,-Bstatic -lstdc++</code>). Not run on Windows yet. Sync test (native build of the same worktree, 20:44 to 20:46 UTC, live node on 26610/26611 untouched): node A on 27000/27001 with START-NODE.bat's flags (<code>--addpeer=&lt;lan-ip&gt;:26611 --listen=&lt;listen address&gt; --nodnsseed --disable-upnp --nologfiles</code>) connected and started IBD within 20 ms, had 5,144 headers and 1,386 blocks at 7 s, and from 17 s on matched the live node's block count, DAA score, blue score and sink at every 10-s sample over 60 s (5,157 to 5,175 blocks, sink identical 5 of 6 samples, <code>synced=true</code>); every header checked by <code>igneum-lottery-v1-bound</code>. Live node <code>peers</code> 1 -&gt; 2 -&gt; 1. Node B on 27010/27011 dialled A's listener, synced to the same sink within 25 s and learnt the live node from A (outbound 2): a node with <code>--addpeer</code> plus <code>--listen</code> accepts inbound connections (<code>--connect</code> would set the inbound limit to 0, <code>kaspad/src/daemon.rs</code>).

 <p>Machine: Apple M5 Max (18 logical cores), load average 60 to 110 (three other agents building at the same time), rustc 1.99.0. Worktree <code>vendor/igneum-node-r3</code>, branch <code>r3-fixes</code> at <code>5166ee26</code> on top of the rename commit <code>d62708a8</code>. Release builds; the real engine needs <code>--features igneum-pow</code>. Fix: <code>validate_header</code> now runs version, timestamp-not-in-future, parent, vote-key, parents-exist, GHOSTDAG, pruning, DAA-score, difficulty, blue-score, blue-work and past-median checks before the PoW engine; the engine (the one 256 MiB cache per day seed) is the last check that chooses seeds. The engine is process-wide, holds <code>KEEP = 4</code> <code>(epoch seed, day)</code> caches, keeps the chain's current and next day resident, runs at most one build per seed pair and at most 2 at once with a queue of 4 (then <code>PowCacheQueueFull</code>, retryable, not a peer fault). A per-peer p2p guard counts an off-day cold build or a rejected-before-PoW header as a strike; more than <code>IGNEUM_POW_STRIKES</code> (default 2) in an hour disconnects the peer and bans its IP for an hour. Cache build time: one 256 MiB ChaCha12 program-plus-cache build in 222 ms on one core under this load (the engine smoke test on an idle machine earlier the same day measured about 0.2 s; <code>proto-metal</code> reported 273.6 ms for the CPU reference fill under the same load). The honest 20-to-60 s proving lag and the 10 ms CPU verify gate are unaffected. Attack, before and after (ignored test <code>measure_m15_attack_before_and_after</code>, release, <code>--features igneum-pow</code>, <code>validate_and_insert_block</code>, the path <code>submit_block</code> and block relay call into): an honest 10-block chain builds 1 cache (genesis epoch, genesis day). Then 50 headers with bogus timestamps (50 distinct past days) and bogus DAA scores.</p>
 <ul><li>Before (the pre-fix order, replayed by calling the engine with the header's own unvalidated day seed): 50 cold 256 MiB builds, 10,595 ms, and the honest day's entry is evicted (<code>KEEP</code> was 3).</li><li>After (the new order): 0 builds, all 50 rejected (<code>TimeTooOld</code> or <code>UnexpectedHeaderDaaScore</code>) in 14 ms total. The live day stays resident.</li></ul>
 <p>Tests: kaspa-pow <code>--features igneum-pow</code> 8 pass (engine smoke, <code>one_build_per_seed_pair_under_contention</code>, <code>live_days_survive_off_day_builds</code>, <code>build_queue_is_bounded</code>, index and live-day helpers, shared-engine, stub); kaspa-consensus header_processor <code>cheap_checks_run_before_the_pow_engine</code> pass; kaspa-p2p-flows <code>pow_guard</code> 2 pass; the full kaspa-consensus release suite otherwise unchanged. M16 Metal note (R3.5, cheap reconfirmation only): the Apple M5 Max <code>--inline-dataset</code> shortcut at the 256 MiB cache, 256 MiB dataset, under the same heavy load, ran honest 91.7 Mhash/s against inline 5.29 Mhash/s (inline about 17x slower); this is noisier and slower than the idle-machine figures already in <code>proto-metal/MEMHARD.md</code> (10x slower at a 256 MiB dataset, 4.8x at 1 GiB), because the inline kernel is compute-bound and the machine was loaded. The 64 MiB on-die-SRAM emulation M16 wants (inline kernel with a 64 MiB cache, <code>cacheLog2Words = 24</code> in <code>proto-metal/main.swift</code>) is the RTX 5090 run reserved for the maintainers' PC, as R3.5 states; it is not done here and the Apple M5 Max number above does not price a die. Not done: the real-engine daemon RPC run (honest blocks need GPU-mined pow, so the measurement used the equivalent validate path with <code>skip_proof_of_work</code>); the 64 MiB-cache inline kernel on the 5090; the chain-derived day seed by DAA score (spec 01 section 1.12, still the timestamp-day devnet rule); the VDF epoch seed and finality.</p>

 <p>Machine: the same Apple M5 Max, shared with two other build agents (load average 60 to 98 during the Rust builds). Fork worktree <code>vendor/igneum-node-diff</code>, branch <code>difficulty</code> from <code>d62708a8</code>. Everything in <code>docs/analysis/difficulty-2026-10-03.md</code>; raw outputs in <code>sim/difficulty/results.md</code>. Record: 3,682 headers of the overnight devnet pulled read-only through the observer node's wRPC JSON (<code>ws://127.0.0.1:28640</code>, <code>getBlocks</code> from genesis) into <code>sim/difficulty/devnet-2026-10-03.csv</code>. Kaspa's sampled DAA held genesis difficulty 134,217,727 through block 600 at 0.6 blocks/s (PC, 116 MH/s estimated from the blocks), then eased 4.8x at the first retarget (DAA 600, 19:56:12 UTC) and on to 15.7x (8,552,118) because the 600-block window spanned the 21-minute Metal-only period and a 13-minute idle gap; 5.44 blocks/s over the next five minutes, 355 blocks in the peak minute, 1,633 blocks above 2x, then 1.5x too hard; the DAG widened to 3,681 blocks for 1,656 chain blocks. Exact replay of the record's bits through rusty-kaspa's integer arithmetic matches 244 of 244 retargets while the devnet was a chain and diverges from DAA 845 (merged blocks a chain-only replay cannot see). Simulator <code>sim/difficulty/sim.py</code> (Python, one chain, exponential solve times, 1 BPS): Kaspa sampled DAA, Monero 720, LWMA 60 and 120, the Igneum rule and the brief's literal trigger, on nine synthetic profiles plus the record. Two design findings: Zawy's average-target LWMA estimator is biased while targets ramp (the fast lane stalled at 15x of a 50x step), so every Igneum lane uses work over time (Kaspa's <code>estimateNetworkHashesPerSecond</code> estimator); the brief's trigger (short-window rate off target) chatters once the short window is back on target while the long window is still polluted (polluted case 1,876 s against 70 s), so the trigger compares the two lanes. Tuned on the synthetic set only: short window 120, hold 8, prior 16, long lane from 600 blocks of the epoch, trigger 25%, harden 3% per block, ease 10% per block, solvetime cap 20 T. Settled seconds (121-block mean within 10% for 100 blocks), Kaspa / Monero / LWMA60 / LWMA120 / Igneum: x50 step 1,542 / 94 / 105 / 231 / 62; /50 step 12,296 / 6,433 / 578 / 1,074 / 657 (worst gap 179 / 187 / 119 / 65 / 35 s); epoch +-30% steps 1,583 / 456 / 157 / 153 / 144; 10x hopping never / 284 (6 of 12 never) / 264 / 326 / 212; polluted window 2,748 (peak 7.9x) / 124 (peak 15x) / 66 / 110 / 70; genesis 10x too hard never / 287 / 155 / 188 / 322; steady std of rate 0.012 / 0.037 / 0.131 / 0.092 / 0.038; the record's 75x step never (peak 7.6x, 2,340 blocks above 2x) / 136 / 75 / 157 / 79. With +-500 ms timestamp jitter the ordering holds (Igneum x50 169 s, /50 1,047 s, epoch 55 s, polluted 71 s). Implementation: <code>DifficultyRule { KaspaSampled, IgneumDual }</code> as a network parameter (IgneumDual on all four networks, <code>"difficulty_rule": "kaspa-sampled"</code> in the override file selects Kaspa's), <code>OverrideParams.genesis_bits</code> (genesis hash recomputed) for test networks, <code>SampledDifficultyManager::igneum_difficulty_bits</code> over a selected-chain walk plus the in-epoch samples of the existing window, pure integer core <code>igneum_target</code> (Uint320). <code>cargo test -p kaspa-consensus --lib difficulty</code>: 9 pass (hold, steady state, 3% harden, 10% ease, trigger, epoch shrinkage, max target, Kaspa's two level-work tests); <code>cargo test -p kaspa-consensus-core --lib params</code>: 4 pass. The miner now takes the genesis from the node (pruning point before the first pruning) so it mines an override-genesis network; before the fix it hashed the compiled devnet genesis as the epoch seed and every block was rejected. Test network (ports 26800 to 26821, appdir /tmp/igneum-diff-test, override file with <code>difficulty_rule</code> and <code>genesis_bits</code> 0x1e200000): 3 igneumd nodes, 3 CPU miners of 4 threads (A for 1,200 s; B and C from 359 s to 779 s), 1,133 blocks, 0 rejected, one sink. Delivered hash rate 0.0653 / 0.0988 / 0.0686 MH/s (the join is x1.51, not 3x: shared cores at load 50 to 90). Genesis 4x too hard. Measured first within 10% of 1 block/s (61-block mean): warm-up 132 s, join 214 s (23 s to first touch), leave 85 s; simulator on the same profile, 5 seeds: medians 263 s, 61 s, 231 s; worst gap 7.3 s. Kaspa's rule on the same genesis: no retarget inside 20 minutes in any seed (600-block dead zone). Kaspa's rule live on the same genesis, 10 minutes: 70 blocks, bits unchanged on all 70, 0.08 blocks/s, worst gap 63 s, never within 10% of target. Not done: no DAG in the simulator (red blocks' work is ignored by every lane, as by Kaspa's estimator); Monero and LWMA reproduced from memory (approximate); real-time targeting left out; the chain walk (600 reads per header early in an epoch) must be re-measured before the 4 BPS step.</p>

Rule as implemented: <code>docs/spec/03-finality.md</code> section 3.10 and <code>docs/fork-divergence.md</code> "Finality v2". Crypto: blst min-pubkey BLS12-381, votes over <code>"igneum-vote-v1/" || chain_id || 0 || index || hash</code>, sortition VRF = SHA-256 of the sortition signature, aggregate certificates with a bitmap over the canonical voter list.

Test network (<code>--devnet --devnet-suffix=7</code>, network id igneum-devnet-7, genesis bits 0x1e400000 through <code>--override-params-file</code>, finality params as devnet): three igneumd nodes on gRPC 26650/26660/26670, p2p 26651/26661/26671, wRPC JSON 28650/28660/28670 (nodes 2 and 3 <code>--addpeer</code> node 1, node 3 also node 2), peers at protocol version 12; four 4-thread CPU <code>igneum-miner mine --engine igneum-pow</code> identities m1, m2 (node 1), m3 (node 2), m4 (node 3); 20:59:48 to 21:53 UTC. Block rate 0.25 blocks/s per miner (m1: 736 blocks in 3,000 s, 0.072 MH/s, 0 rejected), 2,193 blocks at 21:35 UTC; difficulty 149,037 at DAA 2,193. Key reveal: all four keys revealed from the first block of each identity (<code>Finality: vote key revealed</code>), hash matches the header on all three nodes. Weights at checkpoint 4 (DAA 119): 34 + 31 + 30 + 24 blocks, total 119, 4 voters, participation 1.0 (all keys younger than the presence window). Checkpoints and locks, steady state (indices 1 to 72, all four voting until the equivocation at 43, three after): 72 of 72 determined checkpoints locked on all three nodes; lock latency from determination to lock on node 1: median 0.80 s, p90 1.08 s, max 1.55 s (the vote round trip is bounded by the miners' 1-s poll); first lock 61 s after the first block (checkpoint 1 at blue score 31). Certificates built by the first node to see quorum: node 1 built 91, node 2 92, node 3 90 of 93, 0 conflicting certificates on any node; identical checkpoint hashes, states, signed and total weights on all three nodes at every RPC sample (getFinalityCheckpoints on 28650, 28660, 28670). Checkpoint 2 and 3 locked with 3 of 4 votes (74.6% and 73.0% of total) because the per-template vote carriage and the 1-s poll leave one vote outside the aggregator's first certificate; the lock still met both tests. Sortition: with 4 voters every voter is eligible (threshold = 1 when voters &lt;= 8); <code>aggregators</code> lists the keys whose proof verified, 3 to 4 per checkpoint, and the certificate names the local eligible voter of the building node. Equivocation (m4 restarted with <code>--equivocate</code> at 22:19:41): at index 43 m4 submitted a vote for the checkpoint and one for the hash with its last bit flipped; node 3 answered the second with <code>accepted=false equivocation=true</code>, every node logged <code>EQUIVOCATION by key 56da130c... at index 43 ... weight stripped until daa 8512</code>, and from checkpoint 44 the key is <code>voter false, stripped_until 8931</code> (the ban is re-stamped at each detection, m4 kept equivocating at every index), the voter list is 3, total weight excludes its 526 blocks, and locks continued at 3 of 3 votes (checkpoint 64: 938 of 953 active, 1,400 total). Evidence items were carried in blocks (<code>evidence</code> carriers) and re-detected by the follower path; 21 detections on node 3 in 10 minutes. Partition test (m4 stripped throughout, so the honest set is m1, m2, m3 with 33% of weight each): phase A, m3 stopped 22:31:07 to 22:35:10 (240 s): locks continued (72 at the end, signed 1,088 of 1,105 active and 1,563 total). Phase B, m2 also stopped 22:35:19 to 22:47:48 (749 s), m1 alone voting: 0 locks in 12 checkpoints (73 to 84); at the end m1's weight was 696 of 1,759 total (39.6%) and 696 of 962 active (72.3%), so the ACTIVE test passed as the two silent keys decayed out of the presence window and the 56.7% FLOOR alone held the lock back, which is the sim's 3.3.1 scenario on a real DAG. <code>finality_active</code> stayed true until the lock at 72 fell out of the 20-index window. Phase C, m2 and m3 restarted at 22:47:56: the returning miners signed every open index of the presence window, checkpoints 73 to 85 locked within 30 s (determined-to-locked 749 s for 73 down to 121 s for 84, 0 s for 85), 86 to 92 locked at the steady cadence (signed 1,784 of 1,784 at 86, 1,287 of 1,921 at 92, 3 voters). No conflicting certificate and no stall on any node through the heal. Observer and site: <code>tools/observer/observer.mjs</code> with <code>LIVE_TABLE_PREFIX=fintest_</code> against 28650 wrote <code>fintest_live_checkpoints</code> (49 rows, 42 locked at the first sample) and <code>checkpoint_locked</code> events ("checkpoint 42 locked (76.2% of weight, 96.5% of active, 3 votes of 4 voters) at block 0d1405d0"), from both the <code>FinalityLock</code> subscription and the 2-s poll; <code>live_state.finality</code> carried the weights snapshot. <code>site/api/live.mjs</code> adds the <code>live_checkpoints</code> query and <code>locked</code>/<code>final</code> flags per block; <code>site/live.html</code> draws the locked-checkpoint ring, the dashed "final" line at the newest lock and the locked counter. Live devnet follower (<code>igneumd</code> v2 on gRPC 26690, p2p 26691, JSON 28690, <code>--connect=127.0.0.1:26611</code>, never mining): IBD of 5,254 blocks from node 1 in under a second, kept in sync (5,418 blocks at 21:53, 0.70 blocks/s on the live chain), determined checkpoints 1 to 302 within 1 s of IBD; weights at checkpoint 296 (DAA 8,935): 16 keys, 14 above dust, total 7,146 blocks (eight RTX 5090 identities at 862 to 936 blocks, six at 4 to 10), 0 revealed keys, 0 votes, participation 0, 0 locks, <code>finality_active</code> false, exactly as expected while the Windows miners run the pre-v2 binary. RSS 1.1 GB. It only ever receives from node 1 (its protocol version 12 against node 1's 11 means no finality messages in either direction). Open: one stall of all three test nodes at 20:48:43 UTC in the first run (stripped binary, right after the follower, the equivocating miner and the test observer started): all three logs stop in the same second, every RPC times out, CPU 0%, node 1 of the live devnet unaffected; not reproduced in 28 minutes of the same scenario on the symbolized build (lock 40 to 93 without a pause, including the equivocation and the partition). The first run's self-deadlock (<code>compute_weights</code> taking the state lock its callers hold) was found and fixed before that stall, and <code>Router::enqueue</code> is a non-blocking try_send, so the gossip pump cannot deadlock across nodes; cause unknown. Also open: C3 validity rule and F3 pruning bound not enforced; d = 20 chosen without the reorg-depth distribution; the weight walk is O(window) per checkpoint; one certificate per index per node means a certificate often names fewer signers than the votes that exist. Not demonstrated: locks on the live devnet (its miners do not vote yet), the Windows binaries on Windows, a certificate carried into a block and verified by a cold node that missed the gossip (the follower had no votes to receive), the 2-hour presence window at full length (the run was 53 minutes).</p>

 <p>Machine: the same Apple M5 Max (18 cores), shared with two other agents' builds (load 15 to 55). Branch <code>execution-layer</code> in <code>vendor/igneum-node-exec</code>, worktree of <code>vendor/igneum-node</code> from <code>d62708a8</code>; revm 43.0.3, alloy-primitives 1.7.3, alloy-consensus 2.5.0, alloy-trie 0.9.8, axum 0.8.9; viem 2.57.2, solc 0.8.37 (tools/evm-smoke). Release build <code>CARGO_TARGET_DIR=target cargo build --release -p kaspad -p igneum-miner --features igneum-pow</code>: first full build with the new crates about 20 min under <code>nice -n 10 -j 10</code> on the loaded machine; incremental igneumd rebuilds 35 s to 4 min. Test network: 3 <code>igneumd --simnet</code> nodes (devnet block rate and depths, proof of work skipped, chain id 4463) on gRPC 26700/26710/26720, p2p 26701/26711/26721, eth RPC 26790/26791/26792, appdirs /tmp/igneum-exec-test; 3 single-thread <code>igneum-miner --engine stub --hold-ms 2500</code> (exponential hold, mean 2.5 s per miner). Rate: 130 blocks in 120 s = 1.08 blocks/s; 68 chain blocks; selected-chain reorgs 22 in 120 s, depth 1 (17) and 2 (5), identical on the 3 nodes. Earlier run with a fixed 900 ms hold: 3 blocks/s in lockstep rounds and 80 to 92 reorgs in 60 s with flips 45 to 69 deep (equal-work chains kept alive by the hash tie-break); every flip was unwound correctly (state roots identical on 3 nodes at block 32 after 65-deep flips), the fix is Poisson pacing in the miner. Smoke test (<code>node tools/evm-smoke/smoke.mjs</code>, stock viem paths): 87 checks passed, 0 failed, 36 s wall, tip at chain block 78. eth_chainId 0x116f, net_version 4463. Miner 1 (EVM address = low 20 bytes of its vote key hash) held 91.28 IGN at chain block 53 from 80% subsidy shares of 36.59 IGN per blue block (3,168,808,781 sompi x 1e10 x 0.8, launch-ramp day 0 is not applied on simnet's genesis timestamp); proving pool escrow 92.55 IGN at the end. Funding: 3 transfers of 5 IGN, eth_estimateGas 25,380 (21,000 plus the pgas fold and the 15% margin), all status 1, balances exact. 50 transfers between 3 accounts (each sender's transactions to one node, no p2p relay of EVM transactions): all 50 executed in 16 s wall across chain blocks 58 (17), 61 (20), 62 (13); 57 executed transactions in 7 chain blocks over the run, max 20 per chain block; 19 skipped copies (the same miner re-including transactions handed out before its earlier template landed, every one skipped by the nonce rule with no fee and no receipt). Balances of the 3 accounts matched the receipt accounting to the wei (value plus gas_used x effectiveGasPrice plus burnedProvingFee). Transfer receipt: gasUsed 21,000, pgasUsed 200, effectiveGasPrice 2 gwei (base 1 gwei, tip 1 gwei), burnedProvingFee 200 gwei (200 pgas x 1 gwei), minerTip 16,800 gwei (80% of 21,000 gwei), developerShares [burned 4,200 gwei] (unregistered, 20%). Contract call <code>increment(5)</code>: gasUsed 45,354, pgasUsed 1,288, minerTip 36,283.2 gwei (80%), developer share 9,070.8 gwei (20%) credited to the payee the constructor registered (balance delta equal). Deployment via viem <code>deployContract</code>: gasUsed 185,948, pgasUsed 1,438, registry <code>creatorOf</code> = deployer and <code>payeeOf</code> = constructor argument (executor CREATE rule plus <code>register</code>). <code>eth_estimateGas</code> reports the revert of <code>increment(0)</code>; <code>eth_call hashLoop(50)</code> returns; <code>eth_estimateGas hashLoop(200)</code> = 98,900 with the fold; <code>eth_getLogs</code> finds the event. Measured pgas/gas: 0.0095 transfer, 0.028 storage write with event, 0.0077 deployment, 0.0099 averaged (prototype table, below the design's 0.1 to 10 band as expected before calibration). Duplicates in parallel blocks: one identical copy sent to nodes 1 and 2 was included twice (chain blocks 63 and 64, blocks c09c9329... and 3f401bd2...), executed once, the second skipped <code>NonceTooLow { expected: 18, got: 17 }</code>; a conflicting same-nonce pair (different values, one copy per node) executed exactly once (B1), the loser never reached a block because its node's pool dropped it once the nonce had passed (<code>igneum_getTransactionStatus</code>: includedIn [], executed false). Execution time per chain block (node 1, <code>igneum.executionMicros</code>, includes the full-recompute state root): 50, 71, 93, 57, 41, 46, 50 us for the 7 chain blocks with 3, 17, 20, 13, 2, 1, 1 transactions; 71 empty chain blocks averaged 11 us; the same chain block on the 3 nodes: 50 / 192 / 85 us (block 56) and 50 / 88 / 46 us (block 78). State roots as outputs: genesis (registry only) 7e37a9fb19b154d32daf5bf30a50d339a75029fbc9eec9ea20e95439dba5a311; chain block 56 (3 funding transfers) 68cacfd393b00ead784a69b10d57a3e2dd57858029df107b529487a49f393b50; chain block 78 5b18b3a58f6c1d21b22caad4a1dbd9ee8a6394a02db2220255e556a9d4f90878; identical hash and root on all 3 nodes at heights 0, 56, 74 and 78; the root advanced at every block with transactions. Base fees stayed at the 1 gwei floor (segments far below the 15 M gas target). Differential (<code>igneum-exec-diff seq.json</code>, plain revm without inspector, pgas or split, balances adjusted by the exported Igneum-only flows): segments 0 to 78, 57 executed transactions compared (status, gas used, logs), 19 skipped copies confirmed rejected by plain revm at their positions, 10 accounts compared (balance, nonce, code hash), 0 mismatches. <code>cargo test -p igneum-evm-types</code>: 3 passed. Not done: on-disk state and incremental trie (state rebuilt from genesis at start), header fields <code>utxo_commitment</code> and <code>accepted_id_merkle_root</code> kept (proofs_root is an RPC placeholder), body <code>miner</code> field and <code>proofs</code> section, pgas calibration, proving layer, eager virtual execution, eth_getProof/subscribe/debug, EVM transaction relay between nodes, the finality merge (plan in the design document, section 10.4). Test network stopped at the end of the run.</p>

 <p>Machine: Apple M5 Max, 8 threads at <code>nice -n 15</code> while a devnet build and its simulations shared the box (load average 25 to 107), rustc 1.99.0, release build with LTO. New crate <code>igneum-census/</code> (path dependency on <code>igneum-pow</code>, nothing in <code>igneum-pow</code> changed); the instrumented interpreter is checked against <code>igneum_pow::hash_warp</code> on the first warp of every program and against the <code>igneum-genesis</code> spec vectors at start. Commands: <code>igneum-census run --root igneum-census-2026-10-03 --count 100000 --warps 128 --threads 8 --gen default</code> (memory-hard, 1 GiB, day 2026-10-03; 2,797 s), the same with <code>--gen fixed16-fresh --warps 64</code> (1,049 s), <code>--gen fixed16-fresh2 --warps 64</code> (6,650 s, starved to under a core for most of it), and <code>--gen default --closed-form --warps 128</code> (125.6 s once the machine was quiet); <code>summarise</code>, <code>probe</code>, <code>show</code>. Full tables and the rules in <code>docs/analysis/weak-program-census-2026-10-03.md</code>. Current generator, 100,000 programs x 4,096 nonces: loads per hash 24 to 256 (mean 127.9); distinct addresses per hash 24 to 200 (mean 102.4): 19.9 percent of all loads re-read an address the same hash already read, 94.8 percent of programs have at least one such load, 22.5 percent have a pair that cancels to the identity. The Mac rates of the eight bench seeds vary 1.38x by static loads/s and 1.10x by distinct loads/s (3.51 to 3.85 G/s), so the GPU is bound by the distinct count; <code>igneum-second-seed/epoch1</code> (144 static, 104 distinct) hashes at the rate of <code>igneum-second-seed</code> (104 and 104). Weak programs, current generator: 2.43 percent have a register with no injecting write (saturates to all ones); 0.73 percent have a register with a nonce-independent bit, 0.03 percent a whole nonce-independent register, 0.03 percent a load site read at one address by all 32 lanes, 0.68 percent more than 1 percent of final registers at 0 or all ones, 6 programs an output bit past 6 sigma (0.03 expected by chance). Avalanche clean on every program (mean 31.85 to 32.15, every output bit flips 0.473 to 0.523). Mechanisms: no injecting write; zero-absorbing register sets closed under mulhi/mul; or or mul as the last write. Rules: G1 exactly 16 load slots drawn first from slots 1..63; G2 a load reads only a register written earlier in the program and not read by a load since; R-a no cyclically redundant load; R-b every register has an injecting write; R-c 64 fixed warps on the seed-keyed closed-form dataset with no constant register bit, no lane-constant site, saturation under 1 percent, no output bit past 6 sigma, more than 120 distinct addresses per hash on average. Rejection: 95.0 percent under the current generator (the redundancy alone), 38.3 percent under the first form of G2 (the iteration wrap), 5.14 percent under the proposed form (R-a or R-b 3.93 percent, R-c 2.05 percent), so 1.054 candidates per epoch on average; the accepted population does 120.05 to 128 distinct loads per hash, median 128.00. Closed-form check: with the same seeds and nonces on the closed-form dataset instead of the memory-hard one, R-c agrees on 99,961 of the 100,000 proposed-generator programs (2,054 rejected memory-hard, 2,055 closed-form; the 39 that differ sit at a threshold edge, one nearly constant bit or a bias near 6 sigma) and the per-program metrics agree to three decimals, so the acceptance test can be a pure function of the program. Hash-rate spread: today 2.7x between the 1st and 99th percentile program by distinct loads (56 to 152 per hash; 321 to 118 Mhash/s projected on the RTX 5090 at 18.0 G distinct loads/s), 8.3x min to max; under G1 + G2 every program does 128 distinct loads, projected 141 Mhash/s on the 5090 and 28 on the M5 Max, with the 1.10x program-shape residual the only spread left, approximate. One 5090 run of <code>igneum-second-seed</code> (predicted 173 Mhash/s if distinct-bound, 228 if static-bound) settles the reading on NVIDIA. Not done: no GPU run of the new generator; the spec text is proposed in the analysis doc, section 9, not written into <code>docs/spec/01-lottery-hash.md</code>; test vectors are re-cut when the generator rule is adopted.</p>

 <p>Machine: Apple M5 Max (18 cores, 64 GB), macOS Darwin 25.6.0, load average 14 to 45 during the runs (the live devnet, the observer and other agents' builds were running), everything under <code>nice -n 19</code>. Toolchain: SP1 v6.8.1 (<code>sp1up</code>, cargo-prove c84ada1 of 24 Sep 2026, succinct rustc 1.96.0-dev, circuit version v6.1.0), sp1-sdk 6.8.1 CPU prover, revm 43.0.3, alloy-primitives 1.7.3 with SP1's sha3 patch and k256 patch. Code: <code>proving/igneum-prove</code> (guest ELF 2.69 MB, host 54 MB), fixtures cut from <code>tools/evm-smoke/seq.json</code> (the 3-node simnet export, execution-layer commit fb33069) by <code>igneum-prove-export</code>, which replayed all 79 segments from genesis through the ported executor and matched every one of the node's state roots (final root <code>0x5b18b3a5...</code>). Statement: re-execute one chain block (rewards by rule, nonce-rule skip, two-dimensional gas with the prototype pgas table, fee flows with the developer split, state root over the whole in-memory state) and commit the pre-root, post-root, receipts root, gas, pgas and the executed and skipped counts; the host checks the guest's public values against its own native run before and after each proof.</p>

 <p>Reading: at 626 k cycles the block is far below one SP1 shard, so these times are fixed overhead (proof system setup and the recursion stack), not throughput; cycles per EVM gas (9 to 14) is the first data point for the pgas table calibration (R1) and is dominated by the state-root computation over every account plus one secp256k1 recovery per transaction (through the patched k256). Nothing here is a 12 GB-card shard time (ledger P1); that is the RTX 5090 run of <code>proving/windows-wsl2/</code> and then the 3060-class gate. The devnet was not touched. Not done: the Groth16 or Plonk wrapper (ledger P3), MPT witnesses, more than one shard per block, chain recursion, the prover key in the statement (P12).</p>

 <p>Findings (not consensus failures; filed for the ledger):</p>
 <ul><li>F-exec-A (low): the EVM mempool admits a transaction whose <code>gas_limit</code> exceeds the block execution limit <code>B_e</code>. <code>igneum/exec/src/pool.rs</code> <code>EvmPool::add</code> checks funds, nonce and fee cap but never bounds <code>gas_limit</code> by <code>BLOCK_EXECUTION_GAS_LIMIT</code>. Reproduction: fund an account, send a type-2 tx with <code>gas=31_000_000</code> (B_e is 30,000,000) to any node's eth RPC; <code>eth_sendRawTransaction</code> returns a hash (admitted). The transaction can never be selected (<code>EvmPool::select</code> breaks when <code>gas + gas_limit &gt; B_e</code>) nor form a valid block (<code>check_evm_body</code> -&gt; <code>SumGasLimitAboveBlockLimit</code>), so it occupies a queue slot until evicted. Self-limited because admission still reserves <code>gas_limit x max_fee_per_gas</code> in the funds check. Fix: reject <code>gas_limit &gt; B_e</code> in <code>EvmPool::add</code>, as geth rejects <code>gas &gt; block gas limit</code>.</li><li>F-exec-B (medium, griefing): an over-pgas-budget transaction is executed natively in full before it is skipped, and because it is skipped it pays no fee. A transaction whose own pgas exceeds B_p (for example one large modexp, or the 9,000-iter loop above at 30.96 M pgas) is included, executed (10.85 ms of real work here, more for a bigger input), then dropped with <code>BlockProvingBudget</code> and charged nothing (<code>igneum/exec/src/executor.rs</code>: the skip happens after <code>inspect_one_tx</code> runs and before any fee is taken). Every node re-executes it on every inclusion for free, and because the nonce never advances it also head-of-line-blocks that sender's higher nonces (seen here: the 14,000 and 20,000 loops were never includable behind the stuck 9,000). The funds check at admission does not bound pgas (pgas is not known without execution), so a modestly funded account can force repeated free computation network-wide. Fix options: charge the intrinsic plus consumed pgas on a budget skip, cap single-transaction pgas at admission via <code>eth_estimateGas</code>-style simulation, or drop a sender's queue on a <code>BlockProvingBudget</code> skip rather than retrying.</li></ul>
 <p>Not covered here (out of scope for this pass, and because the proving layer is not implemented on this branch): proof records, the native-execution veto, sortition, and the finality lock (<code>proven</code>/<code>locked</code> are always false on devnet v3, so only <code>executed</code> was exercised). These need the proving layer and the finality merge (design 10.4) before they can be attacked.</p>

 <p>What changed (spec 7.5, design 10 note): the inspector meters pgas against the including block's remaining <code>B_p</code> and halts the transaction before the opcode or precompile that would cross it (a precompile over the cap is answered with a revert that spends none of the forwarded gas, and the parent halts at its next instruction); the executor charges an aborted transaction as out of gas for the gas and pgas consumed to the abort, status 0, nonce advanced, receipt <code>pgasAborted</code>; the proving charge never takes a sender past the signed budget. The mempool refuses <code>gas_limit &gt; B_e</code> (F-exec-A) and an estimated pgas above <code>B_p</code> (estimate = simulation at the tip under the cap), the template packs by the estimate, <code>eth_estimateGas</code> and <code>eth_call</code> fail naming the pgas when the cap is hit, <code>igneum_estimateGas</code> returns both dimensions.

R5 one worker at 2^31: 37.01 / 37.75, 1,324 jobs, 4 blocks, flat. R6 eight workers at 2^31: 36.67 / 36.75 summed (4.29 to 5.55 each), 1,314 jobs, 5 blocks, flat. (R5 and R6 ran a different epoch-0 program from R3 and R4, 112 loads per hash, hence 37 against 30.5 MH/s.) Side findings: the <code>difficulty</code> worktree's node panics at <code>consensus/src/processes/difficulty.rs:431</code> ("Work should not exceed 2**192") when fed 85 blocks/s with wall-clock timestamps under the Igneum dual rule (a pump artefact, logged for the consensus-engineer); <code>skip_proof_of_work</code> nodes still log "PoW rejected ... by igneum-lottery-v1-bound" for every block they accept. Not done: the fix applied and measured on the RTX 5090 machine (the acceptance figure is a flat gap at DAA 10,800 with eight identities); the OpenCL event wait checked on the AMD driver; a unit test of <code>seeds_for</code> (the client is concrete).</p>

 <p>Machine: Apple M5 Max, rustc stable, macOS Darwin 25.6.0. Fork: worktree <code>vendor/igneum-node-fin-attacks</code>, branch <code>fin-attacks</code> on master <code>c6d47547</code> to <code>2a00ff55</code> (BLS votes, certificates in coinbase extra data, p2p message 70, the finality RPCs). Build: <code>CARGO_TARGET_DIR=target nice -n 19 cargo build --release -j 4 -p kaspad -p igneum-miner --features kaspad/igneum-pow</code>. Tool: <code>tools/finality-attacks</code> (<code>run.mjs</code>, <code>lib/</code>, README with the proposed fixes). Network: <code>igneum-devnet-800</code>, ports 27800 and up, data <code>/tmp/igneum-fin-attacks</code>, <code>skip_proof_of_work</code> (the hostile miners never hash; each gets its block share from a Poisson clock; every other consensus rule unchanged). Devnet finality parameters: interval 30, depth 20, weight window 7,200 DAA, dust 5, presence 20 indices, 8 aggregators, ban 7,200 DAA, quorum 2/3 of active and 17/30 of total. Durations at SCALE 0.6. The live devnet (26610, 26611, 26640, 26641, 28640) was never touched. Run time 32 min of process time (the machine slept twice during the run, which pauses the monotonic clocks the harness and the miners use, so wall-clock timestamps in the log jump; no result depends on wall time).</p>
 <p>Hostile pieces are test-only flags of <code>igneum-miner</code>, never honest node or consensus code: <code>vmine</code> (Poisson submit at a chosen hash share, decoupled 0.5-s voter), <code>--equivocate</code>, <code>--sybil b:bb:a:ab</code> (one miner mints many vote keys), <code>--drop-votes</code> (strips the node's finality section from its coinbase so its blocks carry no votes or certificates while it still votes over RPC), <code>--pulse burst:on:period</code>, and <code>fin-rpc-attack</code> (malformed, mis-signed, replayed, oversized and non-hex votes over <code>submitFinalityVote</code>). Six voters throughout; three nodes for the cross-node scenarios, two nodes over a TCP proxy for the partitions.</p>

The model is share(T) = (F/2 + R T) / (F + R T) with F the window weight at the cut and R the side's block rate, so the floor holds for T* = 2F / (13R): 74 s predicted at F = 1,439 and R = 3, 84 s measured (sibling losses lower R).

 <p>Failures and the proposed fixes (diffs in <code>tools/finality-attacks/README.md</code>, for gate 3 to ratify; no rule was changed here):</p>
 <ol><li>F17 (S2): <code>is_aggregator</code> draws the 8 aggregators per key. Liveness only, because any node may aggregate and a certificate must still meet Q3 by weight, which the Sybil split does not change. Proposed: draw by weight, <code>output x total &lt; 8 x weight x 2^64</code>, mirroring the spec 7.2 step-2 fix.</li><li>Floor time bound (S6A): the 56.7% floor protects a partition for about T* = 2F / (13R) of DAA time, with F the window weight at the cut and R the majority side's block rate. Approximate, formula only, window slide ignored: on mainnet with a full 30-day window and a 50/50 split at 1 block/s, 9.2 days; a 55/45 split, 2.1 days; 60/40 locks at once (3.3.1 already says so). Minimum fix: state the bound in spec 3.3.1 and 3.9. Rule option for gate 3: evaluate the floor against the weight table of the last locked checkpoint while no newer lock exists, so a stalled side cannot lift its own share by mining; cost: after a permanent loss of weight the floor needs a manual override instead of the 4.1 days of 3.3.1 D.</li><li>F1 (S5): no certificate should form before the window holds a full window of history (spec 3.8, O-3.1). Proposed: <code>min_daa = weight_window</code> (2,592,000 on mainnet, 7,200 on devnet) in <code>FinalityParams</code>, one line each.</li></ol>
 <p>Not demonstrated: certificate injection on the wire (S3, S8 half), the eclipse (S7), the 2-hour presence window at mainnet length, the heal rule of 3.5 (both partitions healed without a conflicting certificate, so it was not exercised).</p>

 <p>Machine: the same Apple M5 Max, shared with other agents' builds and test networks (load 15 to 30). Simulator <code>sim/difficulty/attacks/attacks.py</code> over <code>sim/difficulty/sim.py</code> (controllers unchanged): several miners with on/off strategies, block attribution by hash share at the solve, hashes per miner, timestamp forging inside the fork's rules (132 s ahead, above the 27-sample past median). Node runs on branch <code>diff-attacks</code> of <code>vendor/igneum-node</code> (worktree <code>vendor/igneum-node-diff-attacks</code>, from <code>difficulty</code> at <code>3ea7a3e3</code>; adds only the attack variable <code>IGNEUM_ATTACK_TS_OFFSET_MS</code> in the template builder and a reproduction test), ports 27700 to 27721, appdir <code>/tmp/igneum-diff-attacks</code>, genesis bits <code>0x1f010000</code>. Everything in <code>sim/difficulty/attacks/README.md</code>, raw tables in <code>results.md</code>, headers of the three test-network runs in <code>testnet/</code>. Simulator, seeds 7 to 9, Igneum / Kaspa's rule, criterion, verdict: (1) pool hopper 10 to 100% of the base, on while D is below its 6-hour mean, 24 h: hopper's blocks per hash +1.5% at most / +0.8% at most, under 5% both, Igneum 0.7 points above Kaspa's in every greedy cell (unchanged with the ease clamp at 6% or 3%: the price of a controller that moves inside the hour; a 60 s dwell turns the 50% and 100% hoppers into losers, -1.7% and -4.0%): PASS under 5%, FAIL on "no larger than Kaspa's" by the letter, no change proposed. (2) 50x burst for 10 min every hour: pulser's weight per hash 0.26 / 0.98 of the base's, blocks per hash 3.7% / 85% of the base's; once: 0.13 / 0.87: PASS (no weight amplifier under either rule; Kaspa's makes the burst cheap, Igneum's makes it 27x dearer; the hour after costs the base 37% and a 153 s worst gap under Igneum). (3) forger at 30 or 50% stamping at the latest allowed, the earliest allowed, or alternating: Igneum block rate 0.66 / 0.42 / 0.51 at 30% and 0.56 / 0.12 / 0.23 at 50%, difficulty 1.5x to 9.9x on an unchanged hash rate, worst gap 234 s; Kaspa's rule +5% to +11% easing: FAIL both, Igneum far worse. Cause: the symmetric per-step clamp turns every forged block and the honest block after it into zero measured time (spec 2.3's "the next honest block cancels it" is the bug, not the defence), so the lanes measure 1 - 2a(1 - a) of real time at share a; past-stamping also drags the past median down without bound. (4) 25% miner on and off every 120 blocks: std of the rate ratio 0.160 / 0.147 against 0.045 / 0.010 steady and a 0.143 floor from the attacker's own square wave: FAIL by the letter for both, neither oscillates (12% and 3% above the floor), no change proposed. (5) hold dodger 30%, hold flooders 10x and 30%: 0.0 / +0.7 / +0.3% against 0.0 / 0.0 / -0.1%: PASS. (6) 10x miner leaving at block 600 of an epoch, where the long lane takes over: settled 303 s (292 s with the short lane engaged at the switch), worst gap 17 s, against 334 s for a leave at block 1,200; Kaspa's 2,910 to 3,540 s: PASS. (7) side finding, blocks every 12 ms fed to the rule (another agent's pump): the target passes below 2^64 after 4,142 blocks and <code>calc_work</code> panics at <code>difficulty.rs:431</code> (<code>should_panic</code> test <code>igneum_flood_at_85_blocks_per_second_drives_the_target_below_block_work_range</code> on <code>diff-attacks</code>): FAIL, floor proposed. Test network, 3 <code>igneumd</code> nodes, honest 4-thread miner A on node 1 for 15 min, forger F (4 threads, about 50%) honest on node 2 for 5 min then on node 3 with the offset: Igneum, earliest allowed stamp: 0.97 blocks/s at difficulty 91,000 before, 0.24 blocks/s at 275,000 during forging and 0.20 at 341,000 in the last 5 min, forger offsets -121 to -566 s, hash unchanged (A 0.078, F 0.069 MH/s). Igneum, latest allowed stamp (+134 s): 0.98 blocks/s at 89,000 before, 0.59 at 170,000 during, 0.50 at 191,000 in the last 5 min (A 0.112, F 0.110 MH/s); the simulator's 50% cases give 0.12 at 9.9x and 0.56 at 1.8x. Kaspa's rule, earliest allowed stamp: 1.73 blocks/s on a 2.5x too easy genesis to block 600 at 210 s, then 1.02 blocks/s at 83,400 through ten minutes of -180 s stamps. 517, 767 and 1,454 blocks, 0 rejected. Proposed (README.md, diffs, not applied): Part A, timestamp rules: 10 s future tolerance (<code>FUTURE_TOLERANCE_MS</code>, a new constant so the past-median window keeps its 27 samples) and a floor at the selected parent's timestamp minus 10 s (<code>BACK_TOLERANCE_MS</code>) beside the past median; Part B, the chain steps of the short and epoch lanes measured on a sanitised running clock c(b) = max(c(p) + clamp(t(b) - c(p), -20 T, +20 T), t(b) - 60 T), step = min(c(b) - c(p), 20 T), stored per header, so forgeries telescope instead of cancelling; the long lane unchanged. Measured, both parts, 3 seeds: the 50% forger drifts the rate +0.7% (past), +0.9% (future), +1.1% (alternating), worst seed +2.7%; base profiles unchanged except down50 762 s against 782 s, warm-up 327 s against 381 s, polluted peak 11.4x against 8.0x; the other attacks identical. Either part alone fails (unchanged rule under the tight rules: -36% and -83% to past-stamping; the clock under the 132 s rules: collapse at 50%, a martingale once the forgery range exceeds half the cap). Part C for the flood: clamp the output at <code>MIN_DIFFICULTY_TARGET</code> = 2^128 beside the existing maximum, in both rules. Not done: the candidate in the node (simulator only; the per-header clock is a store change); DAG effects of forged stamps on red and merged blocks (one chain in the simulator); a rule change for the hopper's 0.7-point excess (none found that keeps the controller fast; README.md, scenario 1); Kaspa's rule under the flood (same hole, 17x slower, not run).</p>

The live devnet (26610, 26611, 26640, 26641, 28640) and the other agents' nodes (26680, 27700 to 27720, 28680) were never touched.</p>
 <p>The two diffs. (1) F17: <code>is_aggregator(output, weight, total_weight, aggregators)</code> is eligible when <code>output x total &lt; aggregators x weight x 2^64</code> (was <code>output x voters &lt; 8 x 2^64</code>, drawn per key); <code>ingest_vote</code> passes the key's weight and the table total. A key split into n parts holds n thresholds that sum to the one it had; a key without weight never draws; a key at 1/8 of total or more always draws. A node that serves a drawn aggregator aggregates at once; any other node after <code>checkpoint_depth + aggregator_fallback</code> (15) DAA seconds, so anyone MAY aggregate stays the liveness fallback. (2) F1: <code>min_daa = weight_window</code> (mainnet 2,592,000, devnet 7,200); <code>evaluate</code> never locks and <code>ingest_certificate</code> refuses any certificate while the checkpoint's DAA score is below it; the node logs and reports "finality not active, window filling, N of M" (<code>finality_reason</code>, <code>window_filled_daa</code>, <code>window_full_daa</code> on <code>getFinalityCheckpoints</code>).</p>
 <p>Re-run of scenarios 2 and 5 (<code>tools/finality-attacks</code>, hostile <code>igneum-miner</code> from the fin-attacks worktree, unchanged; it drove the fixed node without modification because the new RPC fields are additive). Six voters on one node, <code>skip_proof_of_work</code>, 600 s per run. The harness copy used for the runs is <code>/tmp/igneum-fin-fixes/harness</code> (<code>lib/net.mjs</code> with ports, data directory, network suffix and the finality override taken from the environment; <code>rerun.mjs</code> with the s2 and s5 measurements below); the repo harness was not edited, and its s2 pass test still reads "voters &gt; 8 means per-key sortition", which is now wrong and needs the by-weight test below. Finality override for every run: interval 30, depth 20, window 1,800 DAA, dust 5, presence 20, 8 aggregators, ban 1,800; <code>min_daa</code> 0 for the before runs (the master default) and 1,800 for the after runs (the fixed rule, min_daa = window), fallback 15. The window was shortened from 7,200 to 1,800 so it fills inside a 10-minute run; the rule under test is the equality, not the number.

 <p>Notes. The fallback path ("fallback: any node may aggregate") fired 0 times in both after runs: every voter on the single node is local and, with six keys of similar weight, each is drawn at every checkpoint, so every certificate named a drawn aggregator. The "paused" reading between the window filling and the first lock is the report's label for "window full, no lock yet"; it lasted one sample in s5 and five minutes in s2 (the floor against silent sybil weight, 3.3.1). The repo harness <code>tools/finality-attacks/run.mjs</code> keeps its pre-fix s2 and s5 criteria and should adopt the two measurements above; the fin-attacks miner prints no <code>FINALITY</code> line (that is the fin-fixes miner).</p>

Worktree <code>vendor/igneum-node-diff</code>, branch <code>difficulty</code>, commit "Difficulty: timestamp rules 10 s both ways, sanitised clock per header, target floor 2^128" on <code>3ea7a3e3</code>; built with <code>CARGO_TARGET_DIR=target nice -n 19 cargo ... -j 4</code> on the rustup toolchain (cargo 1.99; the Homebrew cargo 1.69 in PATH cannot read the 2024 edition). Everything in <code>docs/analysis/difficulty-2026-10-03.md</code> section 11 and spec 2.3; ledger M23. The change, the three parts of <code>sim/difficulty/attacks/README.md</code> as proposed: (A) <code>FUTURE_TOLERANCE_MS</code> 10 s in isolation and <code>BACK_TOLERANCE_MS</code> 10 s behind the selected parent in context (new <code>RuleError::TimeTooFarBehindParent</code>), past-median rule and window unchanged, template floor matched; (B) a sanitised clock per header, c(b) = max(c(p) + clamp(t(b) - c(p), -20 T, +20 T), t(b) - 60 T), in a new store (<code>stores::clock</code>, prefix <code>IgneumClock</code> 62, written in <code>commit_header</code>, deleted at pruning, falling back to the parent's raw stamp when the parent has none), the short and epoch lanes walking clock steps min(c(b) - c(p), 20 T); (C) <code>bound_target</code> floors both rules at 2^128. <code>sim/difficulty/sim.py</code> class <code>Igneum</code> carries the same clock and floor. Unit tests: <code>cargo test --release -p kaspa-consensus --lib difficulty</code> 12 pass (the <code>diff-attacks</code> flood test with <code>should_panic</code> removed: every output at or above 2^128, floor reached between blocks 2,000 and 3,000, work under 2^129; <code>both_rules_share_the_target_floor</code>; <code>igneum_clock_steps_pay_a_forgery_back</code>: three blocks 10 s behind their parents then honest blocks, clock steps sum to the 8 s real span, raw clamped solvetimes to -6 s); <code>cargo test --release -p kaspa-consensus-core --lib igneum</code> 9 pass (<code>sanitised_clock_telescopes_a_forged_stamp</code>). Simulator, seeds 7 to 9 (<code>attacks.py --scenario ts --ts-rules tight</code>), forger at 30 / 50% stamping latest / earliest / alternating, block rate after one hour of forging: 1.008 / 1.008 / 1.004 and 1.009 / 1.007 / 1.011 of target (drift +0.4% to +1.1%, worst seed +2.7%), mean difficulty ratio 1.00, worst gap 10.1 s; the 3 October rule under Kaspa's bounds: 0.66 / 0.42 / 0.51 and 0.56 / 0.12 / 0.23, under the 10 s bounds alone 0.636 and 0.170 on the earliest cells. Flood at 85 blocks/s in the simulator: floor reached at block 2,635, no overflow. Pool hopping (<code>--scenario hop</code>, 24 h): unchanged to three decimals, +1.5% at most greedy, -1.7% and -4.0% with a 60 s dwell at 50 and 100%. Base-profile regression, 3-seed means, 3 October against 4 October: record 102.8 against 91.0 s settled (first within 10% 70.3 against 68.5 s); up50 154.4 against 154.4; down50 782.3 against 762.2 (worst gap 78.3 against 73.9 s); epoch30 87.6 against 87.6; hop10 239.4 against 245.1; polluted 70.1 against 74.9 (seed 9: 78.9 against 92.0), peak 8.0x against 11.4x; steady std unchanged. All means within 10%; the two profiles with an idle gap move, because a gap over 60 T is paid back as three 20 T steps instead of one clamped step. Test network (3 <code>igneumd</code> nodes from the fix plus the <code>diff-attacks</code> template hook on a scratch branch, ports 28500 to 28521, appdir <code>/tmp/igneum-diff-fix</code>, genesis bits <code>0x1f010000</code>, honest 4-thread miner A on node 1 for 15 min, forger F 4 threads honest on node 2 for 5 min then on node 3 with the offset, two runs): earliest allowed stamp (offset -1e9 ms, floored by the rules; 986 blocks, 823 chain, 0 rejected): chain rate 0.82 blocks/s honest (60 to 300 s) at difficulty 102,226, 0.88 during forging (300 to 900 s) at 100,134, 0.83 in the last 300 s at 106,141, all-blocks rate 1.00 / 1.02 / 0.95, forger offsets -10 to -90 s (mean -23), hash A 0.110 MH/s, F 0.109. Latest allowed stamp (+9,000 ms; 1,028 blocks, 829 chain, 0 rejected): 0.78 honest at 102,382, 0.89 forging at 96,717, 0.89 last 300 s at 102,754, all-blocks 0.95 / 1.09 / 1.11, offsets +9 to +26 s, hash A 0.112, F 0.111. Flat within the CPU miners' noise; the 3 October rule on the same schedule fell to 0.24 blocks/s at 275,135 and 0.59 at 170,222 (bench-log entry above). Records in <code>/tmp/igneum-diff-fix/ts-past-igneum/record.csv</code> and <code>ts-future-igneum/record.csv</code> (not archived into the repo). Not done: the DAG effect of forged stamps on red and merged blocks (one chain in the simulator); the clock of a header whose parent arrived through a pruning proof starts from the raw stamp (one window of exposure after a sync, unmeasured); upstream's timestamp integration tests assume the 132 s bounds and were not re-run; the hopper's 0.7-point excess over Kaspa's rule stays open.</p>

 <p>Machine: Apple M5 Max, shared (load 8 to 16, another agent's build and the live devnet running throughout), rustc stable, every build and test at nice 19 with 6 jobs into <code>vendor/igneum-node/target-integration</code>.

The hot swap was not in master (no <code>pow_epoch</code> in <code>2a00ff55</code>); it was captured from the uncommitted hotswap worktree as <code>a4224689</code> and merged first.

 <p>Machine: Apple M5 Max, idle at the start (load 3), rustc 1.99.0 (rustup), Swift 5.8.1, builds at nice 10. Decision (the maintainers, this morning): adopt the census's generator rule before any public vector ships. Rule as implemented (<code>igneum-pow/src/generator.rs</code>, <code>src/accept.rs</code>, spec 01 sections 1.4.2, 1.4.3 and 1.4.6; mirrored in <code>proto-metal/main.swift</code> as <code>generateProgramV2</code> and <code>acceptProgram</code> because the Metal worker derives its program from the seed itself): G1 exactly 16 load slots, a uniform subset of instructions 1..63 drawn first by partial Fisher-Yates, the other 48 ops from the ten non-load weights (sum 75); G2 a load's source is drawn from the registers other than <code>dst</code> written by an earlier instruction and not read by a load since; R (a) no cyclically stale load source, (b) every register has an injecting write, (c) 64 units at base nonces from <code>SplitMix64(FNV-1a-64("igneum-accept/" || seed words LE))</code> on the seed-keyed closed-form dataset at 2^28 words with init words = seed words: no constant register bit, no lane-constant load site in any unit, fewer than 164 saturated final values, every output bit within 136 of 1,024, distinct addresses above 245,760 over the 2,048 hashes; a rejected candidate is replaced by <code>seed_words_from_bytes(seed || k_le32)</code>, <code>k = 1, 2, ...</code>, 32 consecutive rejections a consensus fault. Every pack carries <code>generator 2</code>, the attempt and the program id <code>FNV-1a-64("igneum-program/" || 2_le32 || seed words LE || attempt_le32)</code>; <code>igneum-pow</code> is 0.2.0 and the node's engine reports <code>igneum-lottery-v2-bound</code>. The crate is now the pack source (<code>igneum-pow export</code>); the Swift exporter is the Metal cross-check. Version 1 stays as <code>generate_v1</code> for the census and MEMHARD.md levers; its vectors are retired.</p>

 <p>The long-heal run is the measurement the 3 October harness could not make: the old floor fell at 84 s of a young window (S6A); the two-thirds floor on a full 1,800-DAA window held for 150 s and fell at 205 s, 3.25x later as the arithmetic says (2F / (13R) against F / (2R) on a young window, 2W / (15R) against W / (3R) on a full one), and it fell on both sides within 10 s of each other because a 50/50 split crosses the bound at the same moment from both ends. On mainnet the same bound is 10 days of a 30-day window at 50/50 (spec 3.3.1, <code>sim/results_v2.md</code> L4). What the DAG adds to the simulation: after the heal the losing side's blocks are red in the winner's view, so the crossing is sudden rather than gradual, and once either side has certified a checkpoint of its own F1 never lets it back, so the fork is permanent until an operator sets a trusted certificate (F5, not implemented).</p>
 <p>The inclusive comparison at exactly two thirds is pinned by the integer test <code>3 x signed &gt;= 2 x total</code> and the unit test (4 of 6, 2 of 3 lock; the 3 October S6B run had already measured the active test passing at exactly 2/3 with 4 of 6 equal voters); the devnet's 4 side sat at 67.9% rather than 66.67% because block counts are Poisson, and locked at the first checkpoint after the cut.</p>
 <p>Notes. (1) The v4 node logged "PoW rejected ... by igneum-lottery-v1-bound" about five times a second per node (2,952 lines on n0 over 6A) although the override carries <code>skip_proof_of_work</code> and the six miners saw every submission accepted; the window held exactly 1,800 blocks of weight on every node and each side's DAA advanced at 3 per second as planned, so the lines did not move the measurement, but what the v4 pipeline is re-checking there is a question for the consensus engineer before the v4 cut-over (30 of a sample of 200 rejected hashes were later accepted on the same node). (2) The repo harness <code>tools/finality-attacks/run.mjs</code> s6 criterion text and the s5 "below the 56.7% floor" pass test are now stale and should read two thirds. (3) Not done: the two-hour presence window and a 30-day window at mainnet length; the first-month gate under the new floor is unchanged (<code>min_daa</code> = window). (4) The harness's 60-s heal window (6A, 6B) is shorter than the connection manager's redial backoff for a <code>--connect</code> peer after a cut, so a healed proxy does not mean a reconnected n0 inside it; the long-heal run used 300 s and n0 redialled at 59 s after the gate reopened. (5) Stop everything: every node, miner and proxy of the three runs was stopped by the harness at the end of each run; ports 29200 to 29299 were free afterwards (<code>lsof</code> 0 listeners).</p>

 <p>Reading: 15.7x on core and 20.6x on compressed against a loaded laptop CPU. The block is far below one SP1 shard, so these are the fixed per-proof overheads of the proof system on this card; the throughput number needs the larger fixtures (proving e2e standard). Post-state root and receipts root identical to the node's on every stage. Two defects, neither in the proof: the host aborted (exit 134) AFTER writing and uploading the results, in <code>sp1-cuda</code>'s destructor outside a Tokio runtime; and the host was silent for ten minutes between the core and compressed stages with the card idle. Ledger P20. Setup on the RTX 5090 machine needed three package fixes found only by running it on Windows: <code>protobuf-compiler</code> in the apt list, the WSL distro check (UTF-16 output), the elevated window closing; and WSL2 itself needed <code>bcdedit /set hypervisorlaunchtype auto</code> on a PC whose BIOS already had SVM on.</p>

 <p>Package 0.3.0 replaces the build-on-the-PC workers with two prebuilt exes (<code>proto-cuda/nvrtc/worker.cpp</code>: driver API + NVRTC loaded at run time; <code>proto-opencl/host.c --pack</code>: OpenCL.dll loaded at run time, pack read at run time). Both cross-compile with Homebrew mingw-w64 16.2 and import only KERNEL32 and the Universal CRT (1,117,184 and 78,336 bytes stripped). The NVRTC DLLs (12.8.93) add 93 MB to the zip. Checks run on the M5 Max, same protocol script for both (<code>proto-cuda/nvrtc/emu/serve-check.sh</code>: jobs on pack A, a background prepare of a second pack, the swap, a job after the swap, 15 to 17 found hashes against <code>igneum-pow hash-bound</code>):</p>

 <p>The self-test times are dominated by reading the 256 MiB cache back and hashing it on one CPU thread (FNV-1a 64 over 2^26 words); the emulation's dataset build is 256 host threads over 2^24 items and says nothing about a GPU. Nothing NVIDIA was measured: the first NVRTC compile, cubin load and hash rate on the RTX 5090 are owed from the RTX 5090 machine run (<code>proto-cuda/windows-app/TEST.md</code> lists the lines to copy here).</p>

Verified on the seed node (Debian 12, glibc 2.36, 2 vCPU) in <code>&lt;server path&gt;</code>: <code>igneumd --version</code> = igneumd 2.1.0, <code>igneum-miner --help</code> prints its usage, and a 60-s run of the cross-compiled node on <code>igneum-devnet-951</code> (the 60x profile at genesis bits 2^16, real proof of work) with the cross-compiled miner on one CPU thread: the miner adopted the node's 60-block epoch from the template, built its 256 MiB cache in 395 ms, found 7 blocks at 0.011 MH/s, all 7 accepted by the node's own PoW check, 0 rejected (the x86 build of the lottery hash agrees between miner and node; neither binary exposes a standalone vector check). Against the alternatives: the seed's own build took 55 min on its 2 vCPU (4 Oct 2026, above), the builder VM 10 to 25 min on 8 vCPU plus its creation and deletion. <code>BIN_SOURCE=mac</code> is wired into <code>infra/cloud-devnet/provision.sh</code> (no builder VM, build/bin from the cross-compile) and <code>infra/seed-nodes/stage-v4.sh</code> (upload to &lt;server path&gt;, install as before).</p>
 <p>CI. <code>.github/workflows/ci.yml</code> runs on every push and pull request of the private repository: igneum-pow <code>cargo test --release</code> and the igneum-census build (49 s), the two simulators' <code>--quick</code> modes under a 120-s timeout (49 s for the job; <code>sim/finality_v2.py --quick</code> is now a true smoke run, 149 s at nice 19 on this loaded Mac and under 40 s on the runner, was 745 s; <code>sim/difficulty/sim.py --quick</code> is new, 36 s here), the site build, an internal link check of <code>site/*.html</code> (151 links, 0 broken) and a gh-free identity grep of the public export list after the generic scrub (<code>tools/ci/identity-check.sh</code>, <code>tools/ci/forbidden-strings.txt</code>: 157 files, 0 hits). First run green: https://github.com/igneum-network/igneum/actions/runs/37193811336, 54 s from trigger to completion. The node fork is gitignored and too big for the free runners today; the workflow says so.</p>
 <p>Not done: <code>igneum-harness-sim</code>'s per-block cost on the devnet-v4 line (about 70 ms here against 3 ms on the ordering-layer branch, the execution layer's follower) is what still bounds the harness, not the clocks; the fast-time presence window floors at one checkpoint; the GPU workers were not run on fast time (the CPU miner proved the swap).</p>

 <p>Live devnet v4 (genesis 09:05 UTC). The weight window and <code>min_daa</code> are 7,200 DAA seconds, so no checkpoint could lock before DAA 7,200. The first checkpoint past it, index 242 (block <code>59b4a314</code>, blue score 7,261), locked at 11:03:44 UTC with 77.4% of total weight and 77.4% of active weight signed, 12 aggregated votes from 17 vote keys (two RTX 5090 machines with 8 identities each, the Apple M5 Max's Metal miner, the integrated AMD chip's identities), floor 2/3. The certificate (23 headers) was stored and carried in block <code>1e2439a1</code>; <code>observer.mjs</code> logged <code>checkpoint_locked</code> 0.7 s after the miner's own <code>LOCK</code> line. The floor was raised to 2/3 this morning (O-3.15); this is its first live lock. Difficulty at the moment of the lock was mid-oscillation (93M to 99M, see the oscillation finding), which did not affect voting.</p>

 <p>the RTX 5090 Windows rig (RTX 5090 plus the Ryzen's integrated gfx1036), package 0.3.0 prebuilt workers. The CUDA worker compiled the pack with NVRTC (after <code>-default-device</code>) and mined at 124.2 MH/s, equal to the nvcc-built worker, 0 rejected, CPU re-check clean. The OpenCL worker (<code>igneum-worker-opencl.exe --pack</code>, path <code>prebuilt-generic</code>) self-tested PASS and mined correctly at 3.3 MH/s for 577 s (8 accepted blocks), then from about 600 s every job "completed" in 0.5 ms with no hash: 906 jobs became 56,384 within 30 s, the miner reported 4.3 GH/s inside jobs and the dashboard over 1 GH/s, with no error line, no exit and no restart. the three-card Windows rig's cl.exe-built worker on the same host.c serve loop ran over an hour without this.</p>
 <p>Root cause, as far as it can be stated: the AMD runtime kept answering <code>clEnqueueNDRangeKernel</code>, <code>clWaitForEvents</code> and the blocking <code>clEnqueueReadBuffer</code> with CL_SUCCESS while running nothing, so the loop walked its chunks at memory speed and reported the stale output buffer as a finished job. What flipped the runtime into that state at 600 s is not visible in the logs and the job path itself leaks nothing (one event per chunk, created and released; verified below). The two plausible triggers are a device reset of the integrated GPU with the runtime swallowing it (the generic path is the only one that self-tests, which reads 256 MiB back and runs the three vector warps at start; an hourly <code>prepare</code> would do the same work again on a second queue while jobs run) and a runtime limit reached after about 900 jobs. Neither reproduces on Apple OpenCL:</p>
 <div class="tbl"><table><thead><tr><th>Run on the M5 Max (Apple OpenCL 1.2, pack-a, 2^22 nonces per job)</th><th>Jobs</th><th>Job time ms (mean, min, max)</th><th>Faults</th><th>Live objects at the end</th></tr></thead><tbody><tr><td>20-minute soak of the shipped generic worker</td><td>3,365</td><td>412 / 305 / 591</td><td>0</td><td>not counted (that build had no counters)</td></tr><tr><td>1,200-job soak of the hardened worker (events and buffers counted)</td><td>1,200</td><td>411 / 315 / 549</td><td>0</td><td>0 events, 4 buffers (cache, dataset, out, init words); 1,200 events created and released</td></tr><tr><td>the same worker with <code>IGNEUM_FAULT_TEST=6</code> (the dispatch skipped from chunk 6 on, the runtime "succeeding")</td><td>6 real + 1</td><td></td><td>1: <code>the output buffer is unchanged since the previous dispatch</code>, exit 3</td><td></td></tr></tbody></table></div>
 <p>So the fix is defensive at three levels (commit 112acf6 and vendor devnet-v4 f9392600): the worker treats every OpenCL error in the job path as fatal, requires CL_COMPLETE on the dispatch event, refuses a chunk 20x faster per nonce than the running mean or an output buffer unchanged since the previous dispatch, prints live object counts every 200 jobs and exits 3 on any of these; the miner kills and restarts a worker whose job time per hash drops under 1/20 of the mean or whose interval rate exceeds 10x the mean before it, rolls its counters back to the last report and prints <code>WORKER FAULT</code>; the launcher shows <code>worker fault</code> and <code>restarting</code> for that card instead of a rate. The next gfx1036 run says which guard fires first; that line is the diagnosis the Apple M5 Max cannot give.</p>

 <p>the RTX 5090 Windows rig came back from a power cut with its clock 60 s slow. igneumd connected, then logged <code>HandleRelayInvsFlow flow error: the block timestamp is too far into the future: block timestamp is ... but maximum timestamp allowed is ...</code> for every relayed block, processed 0 blocks and the app sat on "waiting for a peer" with nothing to say. The consensus rule is right (a header may not be ahead of the node's clock by more than the tolerance, <code>check_block_timestamp_in_isolation</code>); the reporting was not. The node prints one WARN per relayed block with two millisecond numbers and never the one line a person needs.</p>
 <div class="tbl"><table><thead><tr><th>What</th><th>Where</th><th>Now</th></tr></thead><tbody><tr><td>The app reads that WARN, takes <code>block timestamp - maximum allowed</code> as a lower bound and shows "Your clock is at least N seconds behind the network; mining cannot start until it is fixed" on the node card with a Sync clock button (macOS <code>sntp -sS time.apple.com</code> under an administrator prompt, Windows <code>w32tm /resync</code> elevated, Linux <code>chronyc makestep</code> / <code>timedatectl</code>) and the manual steps</td><td><code>app/igneum-app/src/engine.rs</code> <code>node_line</code>, <code>resolve_clock</code>; <code>platform.rs</code> <code>sync_clock</code></td><td>done</td></tr><tr><td>Independent of the node: once blocks arrive the engine samples the latest block's timestamp through the node's Ethereum JSON-RPC every 10 s and takes the median of local minus block time over the last 9 (behind only; a stalled chain reads as ahead); and an HTTPS Date header from the downloads host at start and every 10 min (either direction, 1 s resolution). Over 5 s: a warning.

 <p>Checked on the Apple M5 Max with a fake 60 s skew (<code>IGNEUM_APP_FAKE_SKEW=-60</code>): the banner, the node card, the blocked Start button and the held miner all showed; with the real clock the HTTPS source read +0.4 s and the block source agreed.</p>

 <p>the maintainers' second PC (a clone of the first; the app's per-install machine id <code>1ccfe586</code> keeps its keys apart), installed from the runner-built <code>Igneum-Miner-Setup-0.3.0.exe</code> (unsigned, SmartScreen "run anyway"), the one-click package: prebuilt NVRTC worker, no toolchain on the machine. First attempt sat at "waiting for peer": the RTX 5090 machine's clock was 62 s slow after a power cut and <code>igneumd</code> rejected every relayed block ("the block timestamp is too far into the future"; the 10-s skew bound from the hardened timestamp rule) and processed 0 blocks for 12 minutes with no visible reason. Clock set by hand; the node caught up (46 blocks in the next 10 s at 11:27:53 UTC), the 5090 started inside the app and ran at 117 to 119 MH/s with 34 accepted blocks in the first minute, CPU re-check OK on every share, the integrated AMD chip at 3.3 MH/s beside it. Two defects from the run, both fixed in the app the same hour: no clock-skew warning (now detected from the node's warning, block timestamps and an HTTPS Date header; Start is blocked above 10 s), and the node card stayed on "syncing" after the late catch-up while the miner was already accepted (state now re-derived every poll).</p>

 <p>Machine: Apple M5 Max shared with four other agents' builds (load average 7 at the start, 184 to 442 from 11:40 UTC on); every simulation and build at nice 19, cargo at 4 jobs; the live devnet (26610/26611, 26640/28640, observer.mjs, the Metal miner) untouched, read through the observer node's wRPC only. Worktree <code>vendor/igneum-node-v4</code>, branch <code>devnet-v4</code>, built in its own <code>target/</code>. Everything in <code>docs/analysis/difficulty-2026-10-04-oscillation.md</code>; ledger M24; spec 2.3 revised. Live finding (devnet v4, UTC): the three-card Windows rig (RTX 5090, RTX 4070, RX 9070 XT) (RTX 5090, 122 MH/s, 8 identities through its own node) with the Apple M5 Max (26.7 MH/s) and a Radeon (2.8) from 09:11; the RTX 5090 Windows rig (RTX 5090, 124 MH/s, 8 identities through the Apple M5 Max node) from 10:12:17, off 10:31:25 to 10:35:19; both PCs restarted at 11:00 for the machine-id package (they are clones with one computer name and had signed with the same vote keys). Difficulty (node convention): flat 56.7M to 67M within 1% per minute from 09:24 to 10:04; 70M to 144M in 90 s after the join; then 101.8M to 164.3M from 10:17 to 10:32 (5 peaks of 1.33x spaced 132 chain blocks, std of log difficulty 0.123, 54 to 81 blocks a minute) and 103M to 150M from 10:37 to 10:54 (4 peaks of 1.35x, std 0.072, a floor rising 110M to 127M) against a true 139M; after the epoch boundary at DAA 7,200 (11:01:52) 69.0M to 72.7M within 1.3% per minute. Stacked clamps in the observer's 2-s polls: "up 15.9%" = five 3% hardens, "down 24.3%" = three 10% eases. DAG: 6,741 blocks to 10:54, 38% of chain blocks merging two or more blues, every merged block blue. Records <code>sim/difficulty/records/live-2026-10-04.csv</code> (8,090 headers, <code>pull_live.py</code>) and <code>live-2026-10-04-hashrate.csv</code> (587 worker STATUS lines from the log intake, by run id and node). Cause: spec 2.3's reference lane is the whole epoch, so a step 7 minutes into the hour left it polluted for the hour; the short lane read 11 to 25% above it; the 25% trigger flipped on the short lane's noise; the clamps turned each flip into a ramp. The DAG's bursts widen the short lane's noise and the stacked clamps steepen each flip; neither starts it. The 3 October simulator stepped at epoch boundaries, so it never saw it. Replay: <code>sim.py --live</code>, a DAG model (miners on two nodes with <code>igneum-miner</code>'s template staleness, templates stamped by the node, GHOSTDAG, the rule as <code>igneum_difficulty_bits</code> runs it, the sampled window per mergeset), one scale fitted to the merge fraction. Join window 10:20 to 10:31, 3 seeds: std of log difficulty 0.115 against the record's 0.134, 4.3 peaks of 1.31x against 4 of 1.37x, 110.7M to 167.2M against 101.8M to 164.3M, 56.7 to 73.7 blocks a minute against 59 to 72, 22 lane flips, the short lane ruling 38% of the time. Whole polluted window: 0.118 against 0.123, 5.3 peaks against 5. The chain-only simulator with a 1.85x step 10 minutes into an epoch: std 0.136 to 0.189 with 96 to 142 flips (v1). Candidates on the live replay (join window, 3 seeds, std of log difficulty / lane flips): v1 0.115 / 22; short lane 240 0.125 / 10; 360 0.107 / 11; ease clamp 3% 0.113 / 20; clamp once per DAA second 0.132 / 21; hysteresis leave at 10% 0.090 / 2 (short lane ruling 78%); median of three 0.124 / 15; soft trigger 0.110 / 13; reference window 1,200 0.108, 900 0.081, 720 0.055, 600 0.024 / 0, 480 0.021 / 0. Adopted: v2 = the reference lane is the epoch lane over the newest 600 DAA score of the epoch, the sampled long lane not consulted: 0.026 / 0, mean 142.6M against 139M true; rejoin window 0.031 / 0; chain-only 0.022 to 0.081. Cost (synthetic set seed 7, v1 / v2): x50 settled 61.7 / 65.5 s (standard under 90), /50 628 / 753 s (worst gap 32 / 62 s), epoch +-30% settled 144 / 143 s, hop10 211 / 200 s, polluted overshoot 0.180 / 0.089, warm-ups equal, steady std 0.038 / 0.049 with blocks-per-minute CV 0.135 / 0.130. Attacks (seeds 7 to 9, v1 / v2): greedy hopper at most +1.5% / +2.5%, with a 60 s dwell -4.0% / -1.5% at 100%; pulsed rental -96.4% / -96.3% with weight per hash 0.262 / 0.262; forger drift +0.4 to +1.1% / -0.8 to +0.5% (worst seed 2.7% / 1.5%); short-lane oscillation gain 3.75 / 3.29; epoch games 0.0 to +0.7% / 0.0 to +0.4%; polluted window settled 287 to 329 s / 288 to 331 s; base profiles 3-seed up50 154 / 150 s, down50 762 / 822 s, epoch30 88 / 88 s, hop10 245 / 233 s, polluted 75 / 76 s, steady std 0.042 / 0.053.

Build 2 min incremental for <code>igneumd</code> and <code>igneum-miner</code>. Test network (<code>sim/difficulty/testnet_v2.py</code>, 3 nodes on 29600 to 29622, the 60x file with the devnet epoch, genesis bits 2^16, activation 900 on nodes 1 and 2, node 3 without it; CPU miners A from 0, B from minute 4, off at 19, back at 23): node 1 reached DAA 900 at 1,022 s; node 3 rejected the first v2 block ("difficulty of 520437997 is not the expected value of 520406991"), banned its peer and stayed at DAA 900 (901 headers, a prefix of node 1's 1,472); nodes 1 and 2 agreed on every header and the sink. Under v2 the leave eased 6,589 to 5,972 over 180 s (std 0.036, no peak), the rejoin hardened 6,154 to 8,312 within 60 s and held within 3%. The v1 phase is not readable: the load swung the CPU miners' delivered hash rate 2x on its own (difficulty fell 40% after B joined). Record <code>records/testnet-v2-2026-10-04.csv</code>. Repeat on a quiet machine, 30 minutes. Rollout: only <code>igneumd</code> changes (the Apple M5 Max build, <code>infra/cross/build-linux.sh</code> for the seed and the the cloud provider nodes, the Windows package for the three-card Windows rig's node); every node of a chain needs the same <code>"difficulty_v2_activation_daa": N</code> in its override file before the height or it forks off there. First the 12 the cloud provider nodes on their own chain (N = current DAA + 1,800, restart one by one, a miner joins inside an epoch, no flips after the height), then the devnet with N about two hours ahead: observer node, seed, Mac node 1, the three-card Windows rig's node, in that order, by the maintainers. A new network sets 0. Not done: a quiet-machine test-network run; the DAG model's red blocks and the Apple M5 Max's log series; v2 with +-500 ms stamp jitter.</p>

Node logs for 11:57 to 13:18 UTC would settle which it was.</p>

 <p>Run <code>win-1ccfe586-20261004-132055</code> (the Igneum Miner app, package 0.3.0 workers). Sequence from the node and miner uploads: the app reinstalled and its node restarted at 13:20:29 UTC in IBD from DAA 17,881, inside epoch 4 (seed 57ac7663...); the app exported <code>packs\devnet</code> from that node's template at once, so both workers started on 57ac. The boundary at DAA 18,000 passed about a minute later. The CUDA miner's first templates still carried <code>next_epoch_seed</code> c23e65dd... within lead: <code>PREPARE sent</code> at 14:20:57, <code>prepared</code> 0.9 s later (NVRTC 151 ms, cache 68, dataset 113, self-test 511 ms), <code>switched to the prepared pair</code> at 14:21:28, then 60 MH/s with 8 identities and 101 accepted blocks in 271 s. The OpenCL worker reported ready 43 s after the CUDA one (14:21:39); by then every template was on c23e as the current pair and no next epoch was within lead, so the miner never sent a <code>prepare</code>, and the worker answered 514 jobs in a row with <code>epoch seed mismatch</code> (one every 0.5 s, the miner's error back-off) for the rest of the run. The message text "holds prepared epoch 57ac..." is host.c's wording for a pack read at run time, which is why the stuck worker looked like a wrong prediction: the RTX 5090 Windows rig's node announced the same next epoch (c23e) as the chain. No node on this PC predicted a different epoch, and the 57ac pack was simply the previous epoch's. Fixes: devnet-v4 miner 3bfe346f (prepare the current pair after a <code>need</code> line or three mismatches; exit 42 without prepare support; restart a ready worker with jobs queued and no job done for 60 s), workers emit <code>need &lt;epoch&gt; &lt;day&gt;</code> before the error. Not measured here: the swap time of the forced prepare on the RTX 5090 machine; the OpenCL run's "2 jobs in 154 s" were the two jobs before the first mismatch and are not a rate.</p>

 <p>Job run-20261004-173115 (the <code>run</code> kind, prove only, as root inside the app's own WSL2 instance), log intake run <code>job-run-20261004-173115-1ccfe586</code>, exit 0 after 1,789 s. Fixtures captured from the devnet: block 338 (one shard at S_p, 11 transactions) and block 341 (two shards, 14 transactions). Every proof verified on the RTX 5090 machine; the three tampered witnesses per fixture (balance, storage or code, dropped account) were rejected before any proving.</p>
 <p>What the numbers say. One RTX 5090 turns a full shard into the 1.27 MB compressed proof the chain carries in about 11 s, and folds a block's shards into one proof in about 2 s more. Against the launch target of 20 to 60 s behind the tip, a single card has 9 s of slack on a one-shard block; a two-shard block needs two cards or two rounds. The 44 cycles per EVM gas and 9 cycles per prover gas are the first measured constants for the prover-gas schedule (spec 7, provisional S_p).</p>
 <p>What went wrong, measured. The job was silent for 24 min 4 s between the core proof (17:40:29 UTC) and the compressed stage (18:04:33 UTC), and 1 min 42 s after the compressed proof: SP1's <code>save</code> writes a proof straight into an unbuffered file, and with the results folder under <code>/mnt/c</code> every field element was one round trip across the WSL2 file bridge. The host now saves through a 4 MB buffer and prints a timed <code>saved</code> line, and the script keeps results on the Linux side and copies them once per stage (ledger P20). The four-shard fixture (block 344) was not run: the script read only its second argument, also fixed. Both fixes are in the package rebuilt at 18:10 UTC; the next job measures them.</p>
 <p>Reading: pending the run. What it decides: the first <code>S_p</code> point (the shard stage time on the card against the 20 to 60 s proof lag of the litepaper), whether the P20 Drop fix holds on the GPU path (exit 0, no abort after the results), and the gap before the first compressed stage (the ten silent minutes of the v0 run).</p>

 <p>A friend of the project installed Igneum Miner 0.3.1 from the DMG on an Apple silicon laptop (machine id <code>3a9bf309</code>, no toolchain, no instructions beyond the five steps in the morning summary: drag to Applications, Open Anyway in Privacy &amp; Security once, Get started, Make me an address, Start mining). Node synced from the seed and the LAN-less path (the seed at the public address first), the Metal worker reported ready and the first block was accepted within the first minutes; after 7 minutes: 33 accepted blocks, 0 rejected, 21.0 MH/s average (24.3 MH/s at the moment of the report), CPU re-check OK on every share. Node 1 counted 7 peers with the laptop connected. The log intake received its uploads every minute under the per-install id, so the machine is observable without any contact from its owner. Observed by the team; the machine is not ours, so this is the first row that is not "the project's own hardware".</p>

 <p>Reading. The whole loop (plan, export, cut, prove, sign, submit, relay, verify, carry, pay) runs and three nodes agree on the payment. The exporter's cut equals the node's cut on the same trace, which is the condition for a prover to prove what the node pays. The 200-pgas shard is the smallest possible (one plain transfer); its 61 s compressed proof on this CPU is a correctness number, not a throughput number, and says nothing about <code>S_p</code>. The verifier's 9.3 s is nearly all SP1 setup per invocation (the pool runs one process per proof); a resident verifier would cut it to the 0.03 s verify. The trust-mode nodes carried the record before node 0 had verified it, which is the v0 limitation of spec 7.7 item 4 in one line: carriage and payout rest on the native statement, verification on the producer's pool policy.</p>

 <p>Reading. Latency: the real inter-region path is 0.3 to 0.7 s per block for 99% of blocks, under the 5-s bound behind GHOSTDAG k and well under spec 03 C1's 2-s inter-region assumption. Partition: the floor rule did what the design says (DECIDED 4 Oct 2026, O-3.15): the 15.8% side locked nothing, the 84.2% side locked every 30-s interval, no index was certified twice, and both sides were on one chain within 15 s of the heal with the minority's 420 to 500 blocks reorged out. The margin is thinner than the weights suggest: certificates carried 8 to 10 of 12 votes with everything connected (signed 66.7% to 89% of total at 14:00 UTC), so during the cut the majority locked at 66.8% twice; the missing votes are the open question (finality owner). Controller: with 12 small steady miners the dual-lane rule overshoots every step (x1.6 to x1.7 on x1.3 to x1.4, x0.53 on x0.75), swings ±20% for 20 min after a step up and then damps, and holds the rate 10 to 20% under target for 10 to 15 min after a step down; none of the settle times is near the simulator's 62 s for x50, and the /1.42 step had not settled in 15 min. The live devnet's two bursty GPU miners oscillate without damping; this network damps. Both regimes are now measured on real timestamps.</p>
 <p>What failed: the first partition ran before the window had filled (no lock possible) and a second was added after the first lock, about USD 0.30; the script's sink-count heal criterion reported 539 and 768 s and is tip churn (replaced with the chain-removal heal time); its first-lock poll reported 807 s because it started after that wait (replaced with the journals); the Apple M5 Max hibernated on a flat battery from 11:56 to 13:16 UTC during the hop schedule, so the 4-thread phase ran 94 min instead of 15 (the scripts now hold the machine awake with caffeinate); the schedule's 4 threads gave x1.42, not x2.5. Another agent's difficulty-v2 rollout (<code>infra/cloud-devnet/rollout-v2.sh</code>, activation DAA 16,170) restarted every node one at a time between 14:14:40 and 14:18:05 UTC, the last 56 s of the second cut and its heal window: the cut-phase locks, the reorg depths and both minority heal times are unaffected (the minority reorgs at 14:15:47 and 14:15:51 came before those nodes' rollout restarts); the majority's first lock after the heal (448, 13 s) was on igneum-01 69 s after its own restart and carries that caveat. Finding for the execution owner: both minority nodes logged "[igneum-exec] reorg deeper than the snapshot ring; replaying from genesis" at both heals. Cost: USD 2.82 net by 14:34 UTC, USD 0.57 per hour while the network stays up (it was left running). Caveats: CPU hash rate only, one afternoon, 12 nodes not 1,000, clocks by chrony.</p>

The lag-proofing stays (it is right on its own), the restart loop stays, and the public-face watch now runs from the same machine, so it also sleeps when the Apple M5 Max does; the fix is the charger and keep-awake, not software.

 <p>Reading. The packaged loop works on a Mac with the CPU prover: 71 s from the tile saying proving to paid on the chain for the smallest shard. The two defects were in the tile's bookkeeping and the child's lifetime, not in the chain rules. The open-shard fallback is what makes a prover without mining weight useful; whether assignees should keep more of the pool is the O-5.1 question, untouched.

 <p>Builds (Mac M5 Max under other agents' load, nice 19, 4 cargo jobs, each into its own target directory seeded from an existing cache; the live binaries untouched), source <code>vendor/igneum-node-v4</code> at 3bfe346f = a21ff239 (difficulty v2) plus a miner-only commit, so <code>igneumd</code> is the a21ff239 node: Mac arm64 144 s (<code>vendor/igneum-node/target-v2/release/igneumd</code>, sha256 8b0fbd27...), Linux x86-64 glibc 2.36 by cargo-zigbuild 173 s (<code>infra/cross/out-v2/igneumd</code>, 70751def...), Windows x86-64 by mingw 8 min 50 s (<code>target-v2/x86_64-pc-windows-gnu/release/igneumd.exe</code>, 27c2ce85...). Each carries the <code>difficulty_v2_activation_daa</code> parser; the Apple M5 Max binary printed <code>Difficulty rule v2 from the override file: active from DAA score 123456</code> on a private suffix, the Linux one on all 12 cloud nodes. <code>cargo test -p kaspa-consensus-core --lib params</code>: 7 pass (the fast-time file already carries the field as never). Windows payload inputs pushed (<code>payload-inputs.zip</code> 66b4dc51...); no manifest published.</p>
 <p>Rehearsal (<code>infra/cloud-devnet/rollout-v2.sh</code>; igneum-devnet-20, its own chain): N = DAA 14,362 + 1,800 = 16,170; staging the 47 MB binary to the four gateways from the Apple M5 Max then gateway to private node (the Apple M5 Max to Hillsboro ran at 32 KB/s; igneum-01 to igneum-04 server to server took 12 s); the 12 nodes rolled one at a time 14:14:39 to 14:18:16 UTC, 15 to 30 s each, every one rejoined within 5 to 15 s with its DAA within 2 of the reference. Watch to N + 600 (31 checks a minute apart): DAA spread 2 to 12 across nodes, difficulty within 1%, moving through N (76.7k at 16,161, 74.5k at 16,344, 86.8k at 16,740). Definitive: <code>getVirtualChainFromBlock</code> from a DAA-14,500 block on all 12 nodes returned the same chain block at DAA 16,062, 16,304, 16,565 and 16,797. No fork. Lesson: <code>systemctl stop igneumd</code> also stops the miner and the block log (<code>Requires=</code>); the script now starts all three (the block logs were off from the roll to 14:56 UTC).</p>
 <p>Hash-rate step under v2 (<code>hop.sh "half:4:600;all:1:600"</code>, 14:57 UTC) against the morning's v1 schedule, first 600 s of each step (<code>results/2026-10-04/v2/compare.md</code>): 2-min rate back within 10% of 60/min after 157 s (v1 161 s) on the step up and 172 s (v1 272 s) on the step down; neither rule holds the 3-min criterion inside 600 s on 12 CPU miners. After 300 s the v1 step-up difficulty swung 128k to 134k to 89k (max/min 1.51, std log D 0.169), the v2 one climbed 102k to 117k (1.15, 0.053); on the step down v2 reached the one-thread level (82k) by 600 s, v1 was at 100k after 600 s and 97k after 900 s. One run each, CPU miners, the v2 series has a bridged gap in its first two rows.</p>
 <p>Devnet: <code>docs/plans/difficulty-v2-rollout-devnet.md</code>. The gap found: the app launched igneumd without an override file, so an OTA-delivered v2 node would have forked at N; fixed with <code>node_override_params</code> in the packaged config (<code>igneum-app.json</code>, one <code>NODE_OVERRIDE_PARAMS</code> line in <code>packaging/mac/packaged-config.sh</code> read by both packagers; the engine writes <code>&lt;app data&gt;/app/override-params.json</code> and passes the flag). Rule: N = DAA at the manifest publish + 10,800 at least; since N is baked at the cut, choose DAA + 14,400 when committing the line and check at publish.</p>

 <p>Rollout: the cloud rehearsal in the morning (12 nodes, one chain through N + 600), then the devnet. Node 1, the observer node and the seed were restarted on the v2 binary with <code>--override-params-file</code> carrying <code>{"difficulty_v2_activation_daa": 33000}</code>; the three app machines received the same height through the signed update manifest (the engine writes it to the node's override file and restarts the node at a safe moment), the two PCs within two minutes of an <code>update-now</code> job, the Apple M5 Max on its next check; the height had first been set to 46,500 and was moved to 33,000 at 16:55 UTC by the same route. The height passed at 17:37 UTC: node 1 and the seed shared the sink (<code>ab6bb0a7147b</code> at block 33,291), the observer followed, both PCs' nodes processed blocks normally, difficulty kept moving (150.8M at the height, then stepping down as the RTX 5090 Windows rig's card paused for a proving job). No node forked; no restart of the chain; a consensus rule changed under a running network with miners on three platforms. The first measurement of v2 on the devnet's own regime (two large miners, bursty parallel blocks) needs the RTX 5090 Windows rig back from its job; the cloud numbers stand meanwhile (settle 157 to 272 s, no swing).</p>
 <p>Third run (job run-20261004-r3-shards, 18:59 to 19:02 UTC, 3 min 22 s wall for the shard and both blocks): the buffered save closed the gap, the core proof finished at 19:00:38 and the compressed stage started at 19:00:39 UTC; shard timings repeated within 0.3 s of the first run (core 9.1 s, compressed 10.5 s). The second run (run-20261004-1912-shards) failed in its first second with a guest that returned 0 bytes of public values; the same sources executed the shard on the Apple M5 Max, and a forced rebuild of every source on the RTX 5090 machine cleared it (ledger P20 closed; the package build now has a gate).</p>

 <p>the maintainers, 4 October 2026 evening: "we need to fix these serious issues before making things public". Both fixes sit behind one height switch, <code>finality_v3_activation_daa</code> (default never on every network, set by the override file like <code>difficulty_v2_activation_daa</code>), on branch <code>finality-fixes</code> of the node (worktree <code>vendor/igneum-node-finality</code>, from the proving head <code>8c0cff15</code>). Spec 03 Q4 (fold) and Q5 (frozen table), 3.3.1, 3.7 items 2 and 9, 3.10, 3.11; ledger F21 and F22 "Fix built, pending rollout"; the devnet plan in <code>docs/plans/finality-v3-rollout-devnet.md</code>. The live devnet was never touched; every network below ran on ports 29700 to 29799, suffix 970.</p>
 <p><strong>F22, what was wrong.</strong> The cloud logs of the healthy stretch 11:45 to 14:00 UTC (212 indices, 12 miners; <code>tools/finality-attacks/vote-timing.py</code>, output in <code>infra/cloud-devnet/results/2026-10-04/f22-vote-timing.md</code>): the node builds a certificate the instant the votes it holds meet Q3, median 1.24 s (p99 1.71 s) after the first node determined the checkpoint, with 7 to 10 of 12 signers (mean 8.27); 10.24 votes had been issued by then on average (two in flight: the miner's 1-s poll, the 250-ms gossip pump per hop, up to 289 ms RTT) and the last of the 12 was issued median 1.45 s, p90 2.36 s after the first determination. A 1-s hold after the first build would have carried all 12 votes at 192 of 212 indices; the other 20 are miners 01, 06 and 11 down together for 10 minutes (indices 377 to 396, the hop.sh restarts), an outage, not lag. There is no cut-off to lengthen: the fix is a second round. Presence needs nothing, since the block reading of Q2 credits a late vote once any block carries it.</p>
 <p><strong>The rule built.</strong> F22: the first certificate still forms at quorum (lock latency unchanged); once every voter has signed, or <code>certificate_fold</code> DAA seconds after the determination (<code>FinalityParams::certificate_fold</code>, 3 on devnet, 6 on mainnet, serde default 3 so every older override file parses), a node holding a certificate rebuilds it from every vote seen when heavier and gossips it; <code>ingest_certificate</code> replaces a held certificate with a verified heavier one over the same block; templates carry the held one; a lock is never withdrawn. F21: <code>frozen_table</code> finds the highest locked index below i whose block is an ancestor of C_i and takes its weight table (bans applied) while <code>daa(C_i) &lt; daa(C_f) + weight_window</code>; <code>evaluate</code> requires the signers (and a held certificate's signers) to hold two thirds of it at its weights on top of Q3; a locked checkpoint is never downgraded; the LOCKED line carries the frozen fraction and index. Node tests (<code>cargo test --release -p kaspa-consensus-core -p kaspa-consensus -- finality params</code>, 20 of 20): <code>frozen_table_holds_a_side_without_the_other_keys_for_one_window</code> (A 60%, B 40%; B leaves; v2 locks A alone within 30 DAA of B's last block, v3 not before the last lock is one 60-DAA window old, then at once), <code>fold_round_carries_late_votes_and_heavier_certificates_replace</code> (4 of 6 lock, a fifth vote is folded in 2 DAA later, a lighter hand-built certificate is refused, a heavier one replaces), <code>override_params_carry_the_finality_v3_activation</code>, the fast-time file test extended to both fields.</p>

 <p><strong>What remains uncertain.</strong> (1) The v3 split's hold was observed over the last 24 s of a 150-s split (the control crossed at 126 s); a longer split under the 240-s expiry (say 200 s) would show more held checkpoints, and the "held by the frozen table" line is logged at debug, which the runs did not enable. (2) No cloud rehearsal: the 12-node the cloud provider network was destroyed at 15:30 UTC, so the 95% target is shown on three nodes with emulated 300-ms links and on the cloud logs' arithmetic, not on the cloud topology itself; the rollout plan names the re-creation and the partition experiment to run first. (3) The frozen reference is the node's own highest lock on the chain, not the certificate carried in C_i's past, so two honest nodes can test one checkpoint against tables 30 s apart; in a connected network those tables differ by a minute of blocks, under a partition both are pre-split, and no run showed a disagreement, but it is a property argued, not proved. (4) The price: a sudden departure of a third or more now pauses finality for a full window (30 days on mainnet) instead of 1.4 to 10 days; a gradual one costs nothing. the maintainers asked for the pause over the fork; the number is stated in spec 3.7 item 2. (5) The fold clock is in memory: a restarted node folds from <code>daa(C_i) + depth</code>, a few seconds late at worst. (6) Binaries, all from <code>finality-fixes</code> 6aa69a45, hashes and checks in the rollout plan's section 2: Mac native <code>fe982a1d...</code> (verified running), Linux <code>7c100fc2...</code> (cargo-zigbuild, 34 min, not run on a Linux host), Windows <code>cc1d1001...</code> (mingw, 12 min 28 s, the v2 exe's DLL set, cannot run here); the Windows payload inputs were staged with <code>push-inputs.sh --no-deploy</code> into a scratch folder and NOT deployed (plan 7a).</p>

 <p>NVIDIA side, what the Apple M5 Max could check: <code>proto-cuda/nvrtc/emu/test.sh</code> PASS on the race build (the race off under emulation, "variants 1 base only, no race (emulation)" logged per pair; 9 source checks PASS, the --serve protocol with prepare, swap and self-heal unchanged, 17 sampled hashes equal to <code>igneum-pow hash-bound</code>); mingw cross-compile of <code>igneum-worker-cuda.exe</code> with the race (<code>build-windows.sh</code>, mingw, static): 1,509,376 bytes, the same imports as the shipped worker (KERNEL32 and the Universal CRT), icon and version block verified; zipped as <code>igneum-worker-cuda-race.zip</code> (429,387 bytes, sha256 321a086e...c4c049) for the the three-card Windows rig (RTX 5090, RTX 4070, RX 9070 XT) job.

 <p>Machine: Apple M5 Max, load average 17 to 92 (other agents' builds and runs throughout), everything at nice 19 under <code>tools/lock/with-lock.sh run</code>.

Private test networks only: one <code>igneumd</code> (devnet suffix 9950, ports 29950 to 29953) for the miner scenarios and the app's own private node (suffix 9960, ports 29960 and 29961) for the app scenarios; the live devnet was not touched.

The control miner paid nothing.</p>
 <p>Reading. The expectation is 1 in 100 templates; the stub miner found a block on most but not every template once the difficulty had risen on three miners at about 2 blocks/s against the 1 block/s target (a and b held about 500 templates each, 5 and 4 of them fee templates at positions 99, 199, ..., and converted 77 to 80% of templates into blocks), so the block share lands near 1% with the sampling noise of 9 events (1.15% here). The exactness claim is on the template side and is the unit test (<code>dev_fee_tests</code>: 100 of 10,000 at positions 99, 199, ...; 0 at <code>--dev-fee 0</code>; exact at 2 to 100%); the chain test shows the fee blocks reach the chain and are counted the same by the miner and by both nodes. Not measured: worker (GPU) mode, where the fee template is one of the templates the background fetcher rotates through once a second per identity, so the share is 1 in 100 templates by time, not by job; and nothing on Windows.</p>

 <p>Machine: Apple M5 Max, 64 GB, load averages 126 to 146 for the whole session (ten or more agents building and running at once). Every count here (blocks accepted, cache builds, RSS before and after) is valid under that load; every latency is an upper bound and is not a number. Private test network of two igneumd on 127.0.0.1 ports 29500+ (node A on 29500/29501/29502, node B on 29510/29511/29512), data under <code>/tmp/igneum-fud-mem/{baseline,after,after2}</code> (the second is pass 1, the third the committed build), the 60x fast-time profile (<code>infra/fast-time/override-60x.json</code>, <code>skip_proof_of_work</code> on, <code>pow_epoch_blocks</code> 60, <code>pow_day_ms</code> 1,440,000) exactly as the red team ran it. The live devnet and other agents' ports were not touched. Every run went through <code>tools/lock/with-lock.sh run</code>, every build and the unit tests through <code>with-lock.sh build</code>.</p>
 <p>What the red team saw (<code>docs/review/redteam-2026-10-04.md</code> rows 5 and 8, ledger M30): on the 0.3.4 build the s6 submit flood grew RSS by +269 MB, the mempool flood by +270 MB, and the s7 block flood took both nodes from 302 to 1,082 MB. The s6 figures were cumulative from one baseline taken before all three loads (<code>rss_peak - rss_baseline</code> in <code>s6-exhaustion.mjs</code>), so the mempool flood's "+270 MB" was the submit flood's growth carried forward; its own cost was 1 MB. The red team's guess (execution-layer records, rejected transactions retained) did not hold: the mempool flood retains nothing measurable.</p>
 <p>Cause, measured: every RSS step is one <code>PoW cache built</code> line in the node log (<code>consensus/src/pipeline/header_processor/pre_ghostdag_validation.rs:136</code>), 256 MiB each. The lottery engine (<code>consensus/pow/src/igneum.rs</code>, <code>IgneumEngine::epoch_for_impl</code>) keyed its resident entries by <code>(epoch seed, day)</code> and built a full <code>igneum_pow::Epoch</code> (program plus the 256 MiB ChaCha12 cache) per entry, keeping <code>KEEP = 4</code> of them, although the cache is a function of the day seed alone (<code>igneum_pow::Epoch::from_seed_bytes</code>: <code>seed_words_from_bytes(day_bytes)</code>; the epoch seed only feeds the program). On the 60x profile an epoch is 60 DAA, so the honest chain rolls an epoch every minute and the 50x block flood every 10 to 20 s; each roll cost a cache build and 256 MiB until the fourth entry, then evictions. The engine runs under <code>skip_proof_of_work</code> too (<code>check_pow_and_calc_block_level</code> always calls it and forces the pass afterwards), so the harness exercised it. The 3 October harness run (this file, "2026-10-03, consensus attack harness") was on the plain devnet profile (3,600-DAA epochs), where no roll falls inside a 60 s flood, which is why it grew 11 to 33 MB; the profile change and the build change were conflated in M30. On the live devnet the same rule means 256 MiB per hour until 1 GiB resident, and a 50x fast miner reaches that in minutes.</p>

 <p>Reading. Before: one cache build per epoch roll (25 rolls in 1,529 blocks, plus the two days) and the RSS steps with them up to five chunks: <code>KEEP = 4</code> plus one evicted 256 MiB chunk the allocator keeps and never returns to the OS (vmmap at 500, 1,000 and 1,500 blocks: 1.3 G resident in the region vmmap labels IOAccelerator, which held exactly the cache chunks; the malloc zones hold 9 to 22 MB). It stays at five: the before node is flat at 1,34x to 1,37x from 514 blocks on. After: one cache for the first day (319 MB at 510 blocks), a second when the fast-time day rolled at 01:36 UTC (both runs; the day cache is per day by design, <code>KEEP_DAYS = 3</code>), 2 of 2 builds in 1,526 blocks against 27 of 27 before; on the devnet profile (24-hour day, 1-hour epochs) that is 256 MiB flat, 512 MiB around midnight UTC, 768 MiB worst case, against 256 MiB per hour up to 1.3 GB before. So per 1,000 blocks: before, 1,300 MB in the first 500 blocks (the four caches plus the kept chunk) then 31 MB; after, 30 MB, plus 256 MiB once per day. The 30 MB per 1,000 blocks is the same on both builds and is not the PoW cache: at 1,526 blocks the after node's non-cache footprint is 584.0 M physical minus 2 x 256 MiB = 72 MB against 23 MB at 0 blocks, and the malloc zones account for 22 MB of it, so most of it is in large <code>vm_allocate</code> regions, which on this node means the consensus database's write buffers and block cache and the consensus in-memory caches filling toward their fixed sizes (rusty-kaspa sizes them in entries for mainnet), not the execution layer (1,526 chain-block records on an empty chain are about 2 to 3 MB, approximate) and not the finality key maps (1 voter here). That is a reading, not a measurement: it needs a longer run to see the plateau (the live node's own figures fit it: 1,081 to 1,193 MB over 52 minutes with no epoch roll is 36 MB per 1,000 blocks). The live app node's 2,258 MB at 4 h 14 min is more than the before build can hold on its own (five chunks plus 30 MB per 1,000 blocks gives about 1.7 GB at 15,000 blocks); the app runs a GPU worker beside the node (Metal buffers and a kernel per epoch), which this harness does not cover, so that node wants its own <code>vmmap -summary</code>.

 <p><strong>G12</strong> is covered by the digest run (the environment's schedule is part of the digest, so a devnet node with <code>IGNEUM_POW_EPOCH_BLOCKS</code> set cannot connect to one without it) and by <code>env_pow_schedule_is_devnet_and_simnet_only</code>; no mainnet node was started tonight. <strong>M31</strong> is covered by <code>largest_coinbase_fits_on_every_network</code>; no simnet network was started tonight (the red team's <code>tools/exec-attacks/net.sh</code> is the run that would show templates on simnet without an override).</p>
 <p><strong>Uncertain.</strong> (1) Every run is fast time (W = 120 DAA, ban 120, depth 20) on three nodes with 100-ms links; the mainnet values are 30 days, 30 days and 60 blocks. (2) The ban run shows one equivocation at one index; the red team's s1 (equivocation at every index, two keys) was re-run on the new build only through the red team's f23 above (0 refusals where the evening had 9 / 3 / 4). (3) The digest-less allowance on devnet and simnet is deliberate for the rollout and is a hole until removed. (4) The reorg run's final pass had the majority lock no index during the first 60 s of the split, so the re-determination at 8 and 9 was exercised, the pending-certificate path only at 10 and 11; the first pass exercised the opposite. (5) The un-determination rule has a unit test and one network pass (<code>reorg-final2</code>) in which the shallow-sink case did not recur, so the rule is exercised by the test, not by a run; the case needs a split whose difficulty drifts enough for blue work to overtake blue score, which happened once in four runs. (6) The red team's f24b is a window-length partition at 6 blocks/s, so it measures F21's stated limit, not F24; a 4/2 cut under 20 s at that rate would be the F24 case.</p>

 <p>Three builds of the same guest sources, three ids. Cause: <code>host/build.rs</code> compiled the guest with <code>sp1_build::build_program</code> on whatever machine built the host, and the guest ELF depends on where it is built. Shown by <code>strings</code> on the two Mac ELFs: 946 anonymous symbol names differ, and the crate hash of <code>igneum_prove_core</code> is <code>Csl6o96CsXEfN_</code> in the main checkout against <code>Cs5Jl7brLd39a_</code> in the worktree (cargo's <code>-C metadata</code> for a path crate includes the checkout path, and rustc's symbol names carry it); the ELFs also embed <code>~/.cargo/registry/...</code> panic-location strings, which differ again on Linux. A different ELF is a different verifying key, so every verifier rejects every other machine's proof ("sp1 vk hash mismatch" inside SP1's <code>verify_compressed</code>), and the node log showed it as a bare <code>NOT VERIFIED</code> after 114 s to 138 s.

Harness <code>tools/finality-attacks/c4.mjs</code> on the fast-time 3-node network (100-ms proxied links), node built on the Apple M5 Max in <code>vendor/igneum-node/target-c4</code> from the fork worktree (an APFS clone of <code>target-036</code>), suites on the RTX 5090 Windows rig through <code>tools/build-job.mjs</code>. The Mac carried two other builds and the M20 live sync throughout; every figure is a count, an index or a second from the harness clock.</p>
 <p><strong>The cause, in the code.</strong> <code>processes/finality.rs</code>: <code>ingest_certificate</code> verified a certificate only when its block was the node's own determination at that index (<code>cp.hash == cert.checkpoint</code>); any other block went to <code>hold_pending</code>, and nothing ever tried the pending certificate against the table at its own block. <code>fork_choice_lock</code> reads <code>state.locks</code>, which only <code>evaluate</code> filled, and <code>evaluate</code> only ever ran over the node's own determination. So a certified checkpoint off the node's chain never became a lock and never constrained the sink search, whatever spec 3.5 says. Second cause, found tonight on the harness: <code>protocol/flows/src/v10/blockrelay/flow.rs</code> skips a relayed block whose blue work is under the virtual's merge-depth root ("hence we are skipping it"), and the certified chain is lighter by construction, so the node on the heavier side never received the certified chain's blocks at all: in the first runs on the fixed consensus n0 held B's certificates by gossip for the whole heal window and B's blocks never arrived (n0's log shows only its own blocks "via submit block" after the reconnect).</p>
 <p><strong>The fix.</strong> Fork: <code>ingest_off_chain</code> (verifies against <code>voters_at</code> of the certificate's own block, Q3 and Q5 by <code>quorum_at</code> from that block's past, the lock chain by <code>off_lock_chain</code>, then LOCKED with a <code>FinalityLock</code> notification and a <code>VirtualStateProcessingMessage::Resolve</code> nudge so the sink moves without waiting for a block); <code>retry_pending_off_chain</code> on every virtual change; the lock-chain guard in <code>evaluate</code> (a determination off the chain through the node's nearest locks never locks and never aggregates); <code>fork_choice_lock</code> reports a lock beyond the depth-based finality point once; <code>wants_unknown_certified_block</code> and the relay-flow bypass of the merge-depth skip while a pending certificate names a block the node lacks (<code>finality_wants_blocks</code> through <code>ConsensusApi</code> and the session). Not gated on <code>finality_v3_activation_daa</code>: rule v2 took the same pending path.</p>

 <p>Reading. With the consensus fix and the sync hook, a node on the heavier chain that receives a certificate for a chain it has never seen fetches that chain, verifies the certificate at its own block, locks it, moves its sink to the lighter certified chain and re-determines its own records onto it (the v2 W 240 row: 0 conflicts, 0 disagreements, every node on B's chain, which is the spec's F1 and the design's Fork choice items 1 to 4). The same holds under rule v3 with the frozen table on (the last row: B certified 11 and 12 during a 140-s split, n0 reconnected 3 s after the heal once the harness dialled through <code>addPeer</code>, adopted 12 by certificate and ended on B's chain with the other two, 0 conflicts, 0 disagreements). The fix does not and cannot cover a partition that outlasts the bound before the certificate arrives (rows 2, 3 and 6): there the node has already locked alone and 3.11.4 keeps that lock, the late certificate is CONFLICTING for the operator. On the live devnet (W 7,200 DAA, two hours) the bound is two hours after a side's last lock, so every partition under that heals by certificate.

 <p>Reading (the NEW finding, ledger C4). With the module off GHOSTDAG alone converges on the heavier chain and the losing side's records re-determine (F24 works when the chain moves). With the module on the overlay holds during the split (A, with 30% of the frozen table, locks nothing; B locks 7 and 8) and then fails at the heal in the shipped node: B's certificates for blocks off n0's chain are "kept pending until the chain decides (no lock at this index)", n0's chain never decides because GHOSTDAG keeps its heavier tip and nothing turns the certificate into a fork-choice constraint, and once n0's last lock (index 7, DAA 209) is one window old (DAA 329) the frozen table stops applying on A's chain ("no frozen table (no lock on this chain inside the window)"), A's two keys are 100% of A's own window (B's post-cut blocks are red there) and n0 locks 10, 11, 12 alone; B's certificates for 10 and 11 then log CONFLICTING on n0 (n0 log, 16:27:04 to 16:29:54 UTC). A finality fork from a 96-s honest partition, no attacker, table intact at the heal; the 150-s run and the v2 control end the same way. The spec's fork choice ("GHOSTDAG among tips through all certified checkpoints", 3.5) is therefore implemented only for certificates over blocks already on the node's chain. Fix named in the ledger entry: verify an off-chain certificate against the table at its own block and let it constrain fork choice (a certificate-driven reorg), then re-determine.

 <p><strong>A second defect found on the way: the pack export race.</strong> the three-card Windows rig's app log since its 19:02 UTC restart (<code>node tools/logs.mjs win-ae432dc7-20261005-190232</code>): <code>worker error: error 0 pack packs\devnet: the epoch seed bytes do not give the pack's IGNEUM_SEEDW_INIT</code> at 19:07:03, 19:07:19 and 19:08:07, so the 9070 XT was not mining at all in the app while this entry was written (my job <code>rdna4-serve-1</code> at 18:43 hit the same folder in the same state). Cause, from <code>app/igneum-app/src/engine.rs</code> <code>prepare_worker</code>: one thread per card, each running <code>igneum-miner export-pack</code> into the one folder <code>packs\devnet</code>; across an epoch change the two exports interleave and the folder keeps one epoch's <code>program.h</code> with the other's <code>seeds.txt</code> until the next export. Fix on this branch: a process-wide mutex around both export sites (<code>EXPORT_LOCK</code>); the second export rewrites the same pack. Not measured in the app yet: it ships with the branch.</p>
 <p><strong>Answer to the maintainers.</strong> The 9070 XT does 2.5 G random 4-byte reads per second from its memory for this access pattern, and the hash needs 128 of them, so about 19 MH/s is this card's ceiling for the current program class, on any slot; it was running at 92% of that. The eGPU link cost 6% per job through the read-back, now removed (17.87 against 16.88 MH/s inside jobs standalone). The duplicate platform that halved it to 8.9 + 9.4 is folded away. The pack race that stopped it is serialised. Nothing else in the worker's control moves the number: the next step for this card is the program class itself (fewer, wider loads per hash would favour AMD's 64-byte lines), which is a consensus question, not a worker one.</p>

 <p>Reading: the cap does not bind on this hash (310 to 314 W under every limit, as the 4 October stability line said), so the power knob is flat at 0.41 MH/W on the 5090 and the saving must come from the clocks; the 90% and 80% rows' rate dips at the same draw are stalls inside those holds (a worker restart or a template wait), not the cap. The clock ladder's first step (2,781 MHz at 575 W) was requested at 15:37:47Z and never measured: the playbook's own watchdog killed the live engine at 15:39:03Z (all three cards mining at 177 MH/s) because its idle clause sampled one log line and read "idle" from a missing match; the 4070's and the 9070 XT's plans never ran. Consequences: the 5090 is probably left with its core clock locked at 2,781 MHz (an <code>-lgc</code> lock persists until <code>-rgc</code> or a reboot) under the 575 W cap, which costs little rate; freeing it needs administrator rights; and the Power Helper was NOT registered by this run (the registration lived only in the installed app's cap path, which a <code>--sweep</code> engine skips). Fixed the same hour: the watchdog's idle rule (three consecutive status lines reading 0.00 MH/s and 300 s, never a missing match), the <code>after</code> snapshot and the engine-log dump on every exit, and an elevated tune engine registering the task itself before its first step. The decided way out: the maintainers switches Power control ON in the 0.3.13 app (its one prompt registers the task from the install folder), a job frees the clock through the task (<code>rgc</code>), the tune runs unelevated through the task.</p>
 <p>Consequence for the tiers: an AMD card is tuned on its power limit alone until its stock core clock is read (a 9070 XT at -30% is the floor the driver allows, 4 steps, 5 minutes); every NVIDIA card's two-knob plan waits on the user's one click on Power control; the re-run on the three-card Windows rig (RTX 5090, RTX 4070, RX 9070 XT) is held until the quit's source is named (the event-log collect) and follows the 0.3.11 rollout (the update clears the jobs folder, so the engine and the helper are fetched again), with the scheduler's slot.</p>

 <p>Branch <code>readwidth</code> (commits 019b014, b970dda, 4badcee, a9e002c, d0018cf and the entry commit); plan and recommendation in <code>docs/plans/read-width.md</code>. Nothing here changes consensus: every class sits behind <code>igneum-pow --class</code> and the default class is generator version 2 byte for byte (<code>igneum-pow/tests/packs.rs</code> passes on the four pinned packs after every commit). Question (the maintainers, after "the 9070 XT on the eGPU" above): would wider reads keep the latency-bound random-access property while closing the vendor gap. Additions from the coordinator: a per-load width drawn from an era-fixed mix, and a written per-warp scratch (measurement only, no soundness claim).</p>
 <p><strong>What a class does</strong> (<code>igneum-pow/src/generator.rs</code> <code>LoadClass</code>, <code>verify::fold_words</code>, the three emitters): a load of W words reads the W-word-aligned address <code>(src AND MASK) AND NOT (W - 1)</code> and folds every word into <code>dst</code> (<code>x = dst ^ w0; x = (rotl(x, 11) * 0x9e3779b1) ^ w[j]</code>); W = 1 is the lottery hash exactly (<code>w4</code> = pack <code>bcc1248b10cc90f2</code>). A mix class draws W per load with one extra <code>below(100)</code> roll per instruction. A scratch class <code>scr&lt;k&gt;k&lt;kb&gt;</code> turns <code>k</code> of the 16 memory slots into read-modify-writes of a 16-byte slot of the lane's share of a <code>kb</code> KiB per-warp scratch (kernels run persistent warps, one per block or work-group; a slot reads as a seed-and-base fill until the unit writes it, behind a per-unit tag). Program ids carry the class. Dependent chain and 32-lane unit unchanged.</p>
 <p><strong>Correctness</strong>: 23 packs (<code>proto-cuda/packs-readwidth/</code>, Rust CPU reference vectors). Every pack passed its three vector units and the cache and dataset checks on Metal (M5 Max, <code>proto-metal/packbench</code>), Apple OpenCL (<code>--bench-pack</code>), the RTX 5090 (NVRTC, <code>igneum-worker-cuda --bench</code>) and, the 16 width and mix packs, the RX 9070 XT (<code>igneum-worker-opencl --bench-pack</code>); the 2^24 batch fingerprints agree across all four runtimes on every pack (for example w16 <code>e7c890445b47af60</code>, w64 <code>836e56e7d496e980</code>, mixB-2 <code>a18ac73098c76007</code>). The clang CUDA emulation (w16, w64, w64x4, mixA-0, mixB-0: 3 of 3 units standalone and 2 of 2 in batch at 2 warps per block) and the clang OpenCL emulation (the same five plus scr2k32 and scr8k128, sub-group 32 and, width packs, wave64 with sub-group shuffles) pass with equal fingerprints per configuration. Acceptance rule on the classes: 60 candidates per class, rejection 0 to 14 of 60 (w16 and w64 as v2; the mixes the same; the scratch classes' distinct-address bound now covers dataset loads only, since a 64-slot lane scratch repeats slots by design). CPU verifier (M5 Max, one core, avg of 50 units, <code>igneum-pow bench --class</code>): v2 0.604 ms, w16 0.610, w64 0.630, w64x4 0.160, mix50-35-15 0.620, mix25-50-25 0.614, scr0k32 0.600 (1.004 on a loaded re-run), scr2k32 0.657, scr4k32 0.458, scr8k32 0.317, scr2k128 0.535, scr4k128 0.458, scr8k128 0.311; per hash divide by 32. The wide reads cost the verifier nothing (a lane's words lie in one item); scratch ops replace item derivations and make it cheaper.</p>

 <p>The 9070 XT rows are 2,048 persistent warps (4,096 within 1 percent), arena 64 MiB at 32 KiB and 256 MiB at 128 KiB, working set 1.4 and 1.6 GiB; its control (17.88, the persistent loop) equals its v2 rate (18.15) within 2 percent, and every RMW share costs it 18 to 33 percent: on AMD a scratch op is a dependent 16-byte read plus a write into a region the 64 MB Infinity Cache does not hold for 2,048 warps, so it is memory work there as on the 5090, not the cached op it is on Apple. Apple OpenCL on the same scratch packs (wall time, <code>--bench-pack --warps 2048</code>): scr0k32 27.85, scr2k32 28.58, scr4k32 32.43, scr8k32 47.93, scr2k128 25.67, scr4k128 27.24, scr8k128 32.93 MH/s, the Metal shape within 4 percent, fingerprints equal. Bytes moved per scratch op: 16 read + 16 written (the tag word included); per hash at 50 percent, 1,024 read + 1,024 written beside 256 of dataset reads. The 5090 at 4,096 launched warps (above its 4,080 resident) lost 2 to 26 percent (scr8k32 90.0 MH/s), so the rows above are the in-capacity launch.</p>
 <p><strong>Readings.</strong> (1) Same count, wider: the vendor gap does not move at 16 B (7.8x) because on the 9070 XT a 4-byte read already costs a 64-byte line and on the 5090 a 16-byte read costs one 32-byte sector, the same as 4 bytes: the memory systems do identical work, only the fold's input grows. At 64 B the gap closes to 4.1x, entirely by the 5090 losing half its rate (its share falls to 0.58 and its DRAM traffic reaches 589 GB/s, 37 percent of the stream: bandwidth, not latency, bounds it), while the 9070 XT and the M5 Max do not move. (2) Fewer, wider (w64x4): 3.7x, but every card runs 4x faster because the dependent chain is 32 loads long instead of 128; the 5090 sits at a 0.56 share (bandwidth), so a chip with more bandwidth per dollar than a GPU gains, which is the Ethash shape the design avoids. (3) The mix: the hour-to-hour spread is 7 to 22 percent of the median per card (the 5090 the widest, because its 64-byte loads are the expensive ones and their count per program runs 2 to 8 of 16); the programs with many 64-byte loads (mixA-3, mixA-5, mixB-2) are the slow hours on the 5090 and the fast ones nowhere. (4) The scratch: on the 5090 every RMW share costs 12 to 48 percent against the persistent control, the 32 KiB arena less than the 128 KiB one (the smaller arena, 64 MiB over 2,048 warps, sits inside the 96 MB L2); on the M5 Max the 32 KiB rows are FASTER than the control (+12 and +74 percent at 25 and 50 percent), because the arena (128 MiB over 4,096 warps) lives in the chip's caches and a scratch op is cheaper than a dataset read, so replacing dataset loads raises the rate: the scratch at these sizes is not memory work on Apple and is partly cached on NVIDIA. The chip row for these variants comes from the ca2-soundness branch; what this entry gives is the GPU cost and the share. (5) Latency-bound shares: v2 0.87 to 1.01 on the three cards, w16 0.84 to 1.03, w64 0.58 (5090) and 0.78 (9070 XT); the Apple M5 Max's shares above 1 are an Apple OpenCL probe under load against a Metal rate.</p>

 <p>Reading: the mixer multiplies the verifier's ALU part only (the 8 dependent misses per item are unchanged), hence 1.45x and 2.1x and not 4x and 8x; the Apple M5 Max's GPU build is latency-bound and does not move with the mixer, so the "under 1 s on every discrete card" half of the x8 rule is the RTX 5090 machine job (five packs, <code>relay/playbooks/mixer-x4-pc1-bench.ps1</code>, waiting for the go). Verification throughput (C19): a quiet 2026 core serves about 1,100 shares per second at x4 and 800 at x8 (1,660 at v2, re-cutting spec 09's 2,270), a 22,000-member pool at one share per 10 s needs 2 cores at x4 and 3 at x8, IBD over 108,000 headers is 1.6 min at x4 and 2.3 at x8 on that core; the 10 ms gate keeps 8.0 ms (x4) and 7.1 ms (x8) of margin on the loaded core, 6 to 7 ms on a 2019-class laptop core (approximate, unmeasured, O-1.14).</p>

The claim at x4 is "under 2x" with the margin thin on the equal-budget convention (a 3.3x factor or a 10 percent larger budget reads 2.0x); the hot table in the added form would have raised it to 2.1x to 2.2x at the 5090's g (kept as measured, not adopted).

 <p><strong>Addendum, 22:15 UTC: the verifier regression, the the three-card Windows rig (RTX 5090, RTX 4070, RX 9070 XT) build rows, and x8 into v3.</strong> The era agent measured the same v2 input with readwidth's binary (0.604 ms) and ca2-v3 HEAD's (1.33) in one minute; bisected under the measure lock to this branch's 0fc0ad1 (seam 6c75dad 0.610, 0fc0ad1 1.332; the "loaded box" reading above was wrong by that factor, the load was real but the 2x was the code). Cause: the item loop (<code>derive_items</code>) inlined into <code>MemhardCpu::fetch</code>; the mask hoisted, the mask constant, and the constant-mask loop inlined all stayed at 1.33, the same loop <code>#[inline(never)]</code> read 0.60 to 0.62. Fix: <code>derive_items_mask</code>, out of line, one instance per cache size with the line mask a constant. Measured the era agent's way (readwidth's binary beside the fixed one, same input, same minute, 22:07 UTC): v2 0.607 / 0.610 against 0.609 / 0.611; on the fixed binary x4 1.238 / 1.237 (2.0x), x8 2.077 / 2.058 (3.4x), worst cold 2.15 ms; the increments (+0.63, +1.46 ms per unit) equal the slow binary's. Lesson, the class: an inlined item loop costs 2.2x and nothing in the suite sees it; a verifier benchmark with a pinned bound in the crate's CI is filed for the next cut, and until then every change to the item loop is measured against the previous binary on the same input in the same minute. the three-card Windows rig (RTX 5090, RTX 4070, RX 9070 XT) (job run-mixer-x4-pc1-20261005, 22:00 to 22:04 UTC, the worker's <code>cache ... dataset ... ms</code> wall line): RTX 5090 dataset 23 to 25 ms at v2, x4 and x8; RX 9070 XT (gfx1201) 72 to 77 ms at all three; every fingerprint equal to the Apple M5 Max's; rates the v2 rate (136.5 to 137.4 and 18.0 to 18.2 MH/s).

 <p>What was built. Three p2p messages after Kaspa's own transaction relay (<code>protocol/flows/src/v10/txrelay/flow.rs</code>): an inventory of admitted hashes, a request for the unknown ones, one answer with the raw bytes (<code>protocol/p2p/proto/p2p.proto</code>, payload numbers 72 to 74). Two flows per peer (<code>protocol/flows/src/v10/evmrelay.rs</code>), a pump that announces the mempool's admitted hashes every 250 ms, a sink trait the execution layer implements (<code>kaspa_consensus_core::evm::EvmTxSink</code>, <code>igneum/exec/src/service.rs EvmTxRelaySink</code>), and the mempool's side: every admitted hash queued for gossip, executed, evicted and invalid hashes remembered (65,536) so a second announcement is not requested, a 50,000-transaction cap, and the hold on block-added in place of the 4-second cooldown (the executor subscribes to consensus <code>BlockAdded</code>; a transaction leaves the templates when any DAG block carries it and comes back if a chain block skipped it). Limits per peer in the table.</p>

 <p>For comparison (this log): the Apple M5 Max CPU on 4 October, loaded, block-56 shard 0: core 83.1 s, compressed 272.3 s; on 3 October the v0 guest on block-78: core 22.0 s, compressed 55.7 s. The RTX 5090: block-78 core 1.4 s, compressed 2.7 s (4 October, mining paused); a full shard at <code>S_p</code> compressed 10.9 s alone and 33.0 s beside the miner; an empty live shard 7.0 to 7.7 s beside the miner (5 October). No fresh Mac run tonight: the measure lock was held from 20:31Z (a read-width <code>packbench</code>, three builds, a 1,500-s proving-v1 network under <code>run</code>) and did not free inside the 10-minute window set for it.</p>
 <p>Reading, and the consequences (the design document, every number). Doubling the cycles added 4.5 s to the core proof and 3.1 s to the compressed proof: about 280 s of a CPU proof is fixed cost in the compressed-proof recursion, so no shard size brings a CPU proof under the launch deadline (20 to 60 s behind the tip) or near the 10-s assignment window; it fits only the v1 unproven deadline (600 s), which pays a CPU prover only when no card has proven the shard in 10 minutes. The 29.5 to 30.5 GB peak RSS means the CPU prover needs 32 GB free: a 64 GB an RTX 5090 on Windows (WSL2 takes half the host's RAM by default), a 32 GB Linux machine, a 64 GB Mac; a 16 GB machine cannot run it at all. Per tier: an AMD-only home miner (8, 12 or 16 GB, Windows or Linux) mines and does not prove, and loses the 20% proving-pool share; Apple silicon the same (the M5 Max mines at 26.7 MH/s, this log, 4 October); a mixed rig proves on its NVIDIA cards and the rig installer's <code>prover_decision</code> already skips every non-NVIDIA card (<code>packaging/linux/bin/igneum-rig-lib.sh</code>, branch <code>rig-install</code>), now a stated requirement; the app's <code>provedefault.rs</code> already keeps proving off on Apple silicon and off without an NVIDIA card. Decision asked of nobody: no CPU tier (the analysis, section 4a); the public line for the site, litepaper and Proving tile is in section 4c ("Proving needs an NVIDIA card with 16 GB or more today ... AMD and Apple cards mine. A prover for them lands when a zkVM ships one"). The first job proved nothing because an apostrophe inside a single-quoted awk program ended the quote and bash refused the loop while the job reported exit 0; the class fix is <code>tools/amd-prove/check-job-bash.sh</code> (<code>bash -n</code> on the embedded bash body before publishing) and the same <code>bash -n</code> inside the job before the run, both shown to refuse the bad body and pass the fixed one.</p>

Against the RTX 5090's measured 136.1 MH/s: class v2 333 MH/s, 2.4x; class v3 41.7 MH/s, 0.31x bare, 0.92x with a 3x fixed-function allowance (approximate), 0.76x at equal silicon. The claim is "under 2x"; the margin is thin on the allowance (3.3x reads 1.0x) and 9% on the budget. Next levers, named: the mixer at x16 (the verifier at about 4 ms per warp; a 2019-class core unmeasured), a hot table small enough to stay resident beside the streaming dataset.</p>

 <p>Apple M5 Max, macOS 26, branch <code>ca2-analysis</code> (base <code>readwidth</code> 4badcee). The probes are standalone (no pack, no lottery kernel): <code>proto-metal/dot4-probe.swift</code> (built <code>swiftc -O -o dot4-probe dot4-probe.swift -framework Metal</code> under <code>with-lock.sh build</code>), <code>proto-opencl/dot4-probe.c</code> (built <code>cc -std=c99 -O2 -o dot4-probe-cl dot4-probe.c -framework OpenCL</code>), both run under <code>with-lock.sh measure</code> (exclusive; nothing else built or measured on the Apple M5 Max during the runs). Shape: a dependent chain of one dot4 per step per lane, <code>acc = dot4(x, y, acc); x = x * 0x9E3779B1 + acc; y = rotl(y, 7) ^ (acc + s)</code>, 1,048,576 lanes x 4,096 steps, work-group 256, best of 3 with a fresh seed per repetition, device time (Metal: command buffer GPU start to end; OpenCL: event profiling). Beside it the ALU chain of the 9070 XT entry (<code>x = x * K + rotl(y, 7); y = (y ^ x) + s</code>, 5 ops per step counted).

 <p>Reading: on this GPU a signed-byte dot4 costs 4.7 ALU-chain steps and an unsigned-byte one 1.6; Metal has no dp4a and no integer simdgroup matrix (MSL 4.1 sections 2.4 and 6.9), so these are the honest Apple costs of a per-lane dot4 family, and an unsigned definition is 3x cheaper for Apple at no cost to NVIDIA or AMD (both carry the unsigned form, PTX <code>dp4a.u32.u32</code>, AMD <code>v_dot4_u32_u8</code>). Apple's OpenCL does not list <code>cl_khr_integer_dot_product</code>; its <code>dot</code> on <code>char4</code> compiled anyway and returned something other than the integer dot (the mismatch), which is why a family's conformance vectors must gate every vendor path on the feature macro, not on "it compiled".

 <p>Reading: one <code>dp4a</code> on the 5090 costs about one ALU-chain step (7.45 T dot4/s, 0.85 of the chain's 8.75 T steps/s); one <code>v_dot4_i32_iu8</code> on the 9070 XT the same (0.66 T, 0.95 of its chain). Emulating the signed dot4 costs 6.0x the instruction on NVIDIA (the OpenCL compiler does not fold the four sign-extended products into <code>dp4a</code>) and 1.38x on AMD. Vendor ratios: the 5090 is 12.5x the 9070 XT on the ALU chain and 11.2x on hardware dot4; against the M5 Max's best (unsigned emulation, 0.55 T) it is 10x on the chain and 13.6x on dot4. The hash itself is bound by DRAM reads, so these per-op numbers bound a family's cost and are not hash rates (<code>docs/analysis/int8-matrix-family.md</code> section 4). Adrenalin's OpenCL C accepts the clang builtin and emits the instruction on RDNA 4 (the third-party RDNA 3 report of the same route is now confirmed on this card); no PC platform lists the Khronos integer-dot extension. The 5090 SM clock read 2,505 MHz before and after (nvidia-smi; 2,850 MHz while mining in the telemetry entry), so the card was idle for the probe.</p>

 <p>Reading: a fresh program compiles in about 18 ms on this card with the Metal compiler service warm, 79 ms for a pack with its dataset kernels, up to 1.8 s cold (the variant-racing entry's first seed), 0 to 444 ms at the fleet's live boundaries (M11). The hot table fill of layer 5 is 0.07 to 0.22 ms (ca2-cache). So the Apple M5 Max's per-epoch compile-ahead is under 2 s without the race and about 38 s with it (M11: 34.0 / 34.9 / 37.8 s), and the race is the only item visible against the 600-s window in which the program is known (lead 1,200 s minus the 600-s VDF, fixed at every epoch length). PC cards, cited in the plan: RTX 5090 NVRTC 151 to 180 ms, prepare 0.5 to 1.0 s without the dataset (M11), race one round about 37 s; RX 9070 XT OpenCL compile NOT MEASURED at the current worker (owed: <code>host.c</code> times <code>clBuildProgram</code> only in the <code>prepare</code> path and no <code>prepared</code> line from gfx1201 is in any upload); Intel UHD build 3.0 to 6.4 s (M11). Floor by the rule (slowest compile-ahead under 10% of the epoch and inside the window, dataset excluded): 600 DAA s, carried by the race at 6.3% of 600 s; with the race off (M11 found base wins on both the 5090 and the Apple M5 Max) the slowest measured row is the Intel iGPU at 1.1%. Consequences per tier and the difficulty-settle constraint (24% of a 600-s epoch in settle at the measured 144 s) are in the plan.</p>

Question (the plan's item 2): replace the fixed-shape mixer (the chip model's 3x fixed-function allowance, 0.31x to 0.92x) with a random item-derivation program drawn per day from the day key stream (RandomX's SuperscalarHash idea, <code>superscalar.cpp</code> read at upstream 7607fb2), keep the 8 dependent cache reads per item exactly, keep the op count per item at or above x8's, and measure the verifier against the 10 ms gate, bit-exactness, the daily build and the hash rate.

 <p>Reading: bit-exact on CUDA (four compilers now agree on both packs); the build and the rate do not move beyond the loaded noise; the number that moved is the NVRTC compile, +1.1 s per pack, because memhard.h's 6,624-statement item function is inside every hash-kernel and race-variant compile (17 variants: about +19 s per epoch, approximate, against a 38 s compile-ahead budget at the 600-s epoch floor), so compiling the item function once a day into its own module is a requirement of the class. Consequences: a 5090 owner pays 1.1 s once a day after that fix and 1.1 s per variant per epoch before it; the Apple M5 Max 0.75 s once a day.

 <p>the maintainers, 5 October 2026: "fix everything else in the numbers tonight". The number under test: the chained segment aggregation cost 9.6 to 9.7 s a block on the RTX 5090 Windows rig's 5090 while the card mined (<code>chain-pc2-pv1c</code>, the entry above), 2.2 s on 4 October with the card to itself. Target: under 3 s a block, the miner's slowdown of the prover under 1.5x, the proof statement unchanged. Branch <code>agg-cost</code> (worktree <code>igneum-wt-agg-cost</code>, from <code>proving-v1</code> 219517f). Host changes (statement untouched, <code>elf/</code> untouched): the aggregation's stdin build timed apart from the prove call, the deferred-proof count and the SP1 knobs in the RESULT lines, <code>--mode chain --save-shards</code> (every shard's compressed proof written next to the results, so <code>--mode aggregate</code> re-runs the same proofs under other settings). Jobs: <code>agg-cost-pc2-1</code> (21:01:20Z to 21:25:11Z, <code>tools/proving-v1/pc2-agg-cost.ps1</code>, the package <code>igneum-prove-wsl2-aggcost.zip</code> fetched by <code>fetch-prove-aggcost</code> 20:55:39Z, built in WSL2 against the live target dir in 5 s, installed to <code>&lt;server path&gt;</code>, the live <code>&lt;server path&gt;</code> untouched, <code>--mode id</code> the pinned pair) and <code>agg-cost-pc2-2</code> (21:34:00Z, the same script). The live prover was switched OFF for the runs (its sp1-gpu-server would otherwise be shared through <code>/tmp/sp1-cuda-0.sock</code> and carry its own environment; <code>gpu_server_before running=0</code>) and ON again at the end. Fixtures: four consecutive live blocks cut from the RTX 5090 Windows rig's own node (86165..86168 at tip 86195, one empty shard each, every one MATCHES natively), the same four for every phase of job 1.

 <p><strong>The fix (four changes, 5a339733):</strong> <code>ingest_certificate</code> ignores an index below <code>keep_from</code> (counted, debug: the echo stops at its source once the seed runs it); the router's overflow policy for <code>IgneumFinality</code> is <code>Drop</code> with a counted warn once per 10 s per peer, never a disconnect; the finality route is subscribed with 4,096 (a checkpoint's worst case is <code>MAX_VOTES_PER_BLOCK</code> 48 votes on each of 30 blocks plus the certificates); the relay flow skips votes while IBD runs (counted, said once per 30 s; certificates still go in and land pending). No consensus change, no digest change. Tests: the overflow-policy table (p2p 33 of 33), the flows crate (19 of 19), a certificate below the window submitted twice (ignored, no gossip, counter 2; an index inside goes the normal way) with the finality tests (12 of 12).</p>

The receiver side of the fix holds under a storm five times the morning's; the source side (the guard) cannot show on the seed until 0.3.13 runs there, and the fresh node's own guard never fires during IBD (its window starts at genesis), which is correct.

 <p>Also measured: the stock SP1 6.8.1 server refuses every card under 24 GB at <code>builder.rs:38</code> and proves the v1 shard on the 4090 (5.6 s, 17.4 GB), the A5000 (6.4 s, 17.2 GB) and the 5090 (8.4 s, 18.3 GB); 2^27 does not fit a 10 or 8 GB card and the v4 server hangs at the card's limit (568 and 904 s until killed) where v5 aborts in 13 s ("FLOOR abort: a device allocation failed at slop/crates/tensor/src/inner.rs:51 ...

 <p>Measured on the rented fleet (RunPod community pods, list prices, 18:45Z): 38 wave pods (4090, A4000, L4, 3090, 3070, 4070 Ti, A5000, 4000 Ada) ran 1,748 MH/s inside jobs (median pod 28 MH/s) for USD 20.44 an hour, USD 0.0117 per MH/s-hour; the 8x 4090 rig 459 MH/s at 1,636 W for USD 5.92 an hour, USD 0.0129 per MH/s-hour; a single 5090 pod 98 to 128 MH/s for USD 0.41 to 0.74 an hour. The live devnet's difficulty read 1,156,040,186 at 1 block a second at 19:00Z, so the whole network was about 1.16 GH/s, and the rented fleet was most of it. The live litepaper's line ("2 GH/s for USD 13/h vs 280 MH/s devnet") is corrected to: 1.75 GH/s for USD 20 an hour on community pods, against a devnet of 1.16 GH/s.</p>

-<p>Consequence: the devnet's hash is rentable for the price of a dinner, so nothing on it is a security result; the counter-ASIC and finality work is tested there for correctness, not for cost. The cost argument only starts at the TH/s scale, where the rental market's supply (not its price) is the limit, and that number belongs in the litepaper with this caveat.</p></article>

+<p>Run A (10 blocks/s profile, star topology, 65 min): 4.87 DAG blocks/s, 1.09 blue blocks/s, 77.6 percent red, tips 250 to 660, max reorg 55, difficulty easing all hour (6,719 to 1,307), the exec follower at 0.05 blocks/s (lag 18,901 at the end). Run B (1 block/s, same boxes, 30 min): 1.41 blocks/s over the window with the join burst, 1.0 blocks/s and under 2 percent red from minute six, tips 1 to 3, difficulty settled in six minutes (453 to 482 M), the exec follower at 0.46 blocks/s. The network lane's read: run A's reds came from node throughput (61 to 345 ms CPU per accepted block at mergeset 8 to 200), not from the star. Per tier the blue rate decides the payout interval (1.09 against 1.19 blue/s: a 4070 at 10 TH/s waits about three days for a paying block either way), so the higher rate buys the solo miner nothing until the node processes a block in under 50 ms at mergeset 248. Recommendation (the lane's): 1 block/s for the testnet and the launch, 10 behind three measured gates.

+<p>Measured at 21:57Z from the hub's last 2,000 blocks: the 38 wave pods held 77.8 percent of the voter weight (mean 2.05 percent a pod), the 14 standing boxes most of the rest, the hands and the hub the remainder; the last lock signed 93.5 percent of the active voters and 89.9 percent of the frozen table (53 of 84 voters on the first certificate). Earlier the same evening the fleet removed 13 miners' GPUs inside three minutes and finality paused for two hours five minutes (18:39:36Z to 20:44:44Z, 42.7 percent of the table gone with earlier leavers; rule v3 holds a full window). From that came the 10 percent rule (never remove more than 10 percent of the live devnet's weight in an hour, <code>tools/fleet/lib/standing.py weight_check</code>) and the wave's wind-down by hourly slices (<code>tools/fleet/winddown.py</code>: slice 1 at 21:58Z took 12 pods and the 8x rig at 8.6 percent of weight).</p>
+<p>When the wave is gone the 14 standing boxes hold about 95 percent of the weight, so from then until public hash arrives the fleet alone is the devnet's finality: a home miner's lock lands only while the fleet is up. What holds it up: every standing box runs under <code>box-standing.sh</code>, which restarts a dead node within one of its 60-second passes (the hub's three deaths tonight: 63 s, 41 s and 56 s to the restart line), restarts the miner with the node, prunes the prover's exports and trims the node log, and runs the exec recovery recipe when the state layer reads zero; <code>lib/standing.py loop</code> re-rents a dead host in the same shape and reports a box behind its wanted binary.</p>
+<div class="tbl"><table><thead><tr><th>Tier</th><th>What it means</th></tr></thead><tbody><tr><td>Home miner</td><td>your lock depends on 14 rented cards staying up and mining; a finality pause is not your node's fault and nothing you can fix; the rule above is what keeps it from recurring on the fleet's side</td></tr><tr><td>Rig</td><td>the same, and a rig that leaves is itself a weight removal: at 459 MH/s on tonight's devnet it is about 20 percent of the weight, over the hour's budget by itself</td></tr><tr><td>Pool</td><td>a pool node is one voter carrying its members' whole weight; a pool restart is the largest single removal on the network and must be sliced like the fleet's</td></tr><tr><td>The network</td><td>finality by miner weight is only as steady as the miners' uptime; until public hash dwarfs the fleet, the fleet's supervisor is a consensus component</td></tr></tbody></table></div></section></article>

+<section class="section compact">
+<div class="container">
+<div class="derived"><p>Here are the limits, stated before anyone else states them.</p>
+        <ul>
+          <li><strong>A proof in seconds.</strong> Not at launch. Proving a full block today needs a cluster of 100 to 200 consumer GPUs, approximate, so Igneum launches with proofs within about a minute and tightens as hardware improves. Users still see their transaction land in one second.</li>
+          <li><strong>A chip is impossible.</strong> No. A chip wired for one program is a bad bet, because the program moves before it ships. A programmable chip is not stopped by the moving target: everything it needs is public at genesis and every drawn parameter is firmware to it (an address permute, a rotator, an immediate table), so the defence against it is the latency-shadow work (class v4) and the price per joule, not the schedule (the Horizon lane analysis, 6 October 2026, section 5.4; ledger M32). The published model (5 October 2026) prices the strongest chip we can name, one with the whole cache on-die computing dataset items on the fly, at 0.92x the hash rate of an RTX 5090 per unit of silicon with a 3x fixed-function allowance, approximate. The same model, drawn out to the chip that stores the dataset (6 October 2026): The strongest recompute chip we can price, holding the whole 256 MiB cache on-die, reaches under 1x per chip against an RTX 5090. A memory-controller chip that stores the whole dataset reaches 1.2x per chip and, in our model, 5x to 9x per joule; the Ethash chips of this class reached 2.1x to 4.8x. The lever against it, program work in the latency shadow, is measured and in its gates: it brings the chip to 2.1x to 3.9x, the range running from a chip core as costly per operation as the GPU’s (k = 1) to the core Bitmain claimed for its withdrawn Antminer X9 (k about 0.33, never measured); the ladder’s second rung takes that bracket to about 2.8x. Sources: the chip model analysis (6 October 2026); the Ethash rows of the ASIC history (Linzhi Phoenix 2020, Jasminer X4 2021, Antminer E9 2022); Counter ASIC 3.0 item 8 (100,000 ops per hash: the chip's per-joule edge over the RTX 5090 falls from 5.6x to 2.1x on GDDR7 at a chip core equal to the GPU's (k = 1) and to 3.9x at the X9’s claimed core (k about 0.33, never measured), the 5090 at 0.2% less rate, gates G1 to G6 in progress). No hash has stayed free of chips forever; Igneum does not claim to. Monero’s RandomX has held for about seven years; the one chip announced against it, Bitmain’s Antminer X9, was withdrawn in mid-May 2026 before any unit shipped, its claimed core (k about 0.33) never measured. That record says nothing about the price of a chip with the 256 MB cache on its die; that price is a cost model, not a measurement.</li>
+          <li><strong>A guaranteed income floor.</strong> No. External proving is a small market today. Igneum's miners' electricity cost in it is close to power, but the price they must charge is the subsidy they forgo, which falls as one over network hash: an edge at scale and nothing more.</li>
+          <li><strong>A memory-hard prototype on every vendor.</strong> Not yet. The 256 MB cache closed the shortcut on Apple silicon (computing items runs 4.8x slower than loading them, measured 3 October 2026). The same ratio on NVIDIA and on a discrete AMD card is Open.</li>
+          <li><strong>Finality in the first month.</strong> No. No checkpoint locks until the 30-day window has 30 days of history. The first month of mainnet is proof of work with a 12-hour depth, and the text above says so wherever a day count appears.</li>
+          <li><strong>A cryptography team.</strong> Not yet. One founder working with AI systems wrote the design and the code; external reviewers are named and paid before gate 3, and every security claim here is a design claim until then.</li>
+          <li><strong>Finality that no amount of hardware can break.</strong> No. A miner holding a third of the last 30 days of blocks can split finality during a network partition, and two thirds can lock a bad checkpoint for a double-spend bounded by the 12-hour finality depth. Reaching a third takes at least ten days of producing every block on the chain, in public; an attacker matching the honest network needs twenty days for a third and never reaches two thirds. That is harder than attacking Bitcoin, where a majority can reorganise at once, and it is the limit of proof of work without stake or an outside chain. Igneum chose those limits on purpose. The floor is also bounded in time: an honest partition that lasts long enough for each side's own new blocks to reach two thirds of its window locks on both sides, about ten days of a 30-day window at an even split, and an operator must then resolve it (measured on a test network, 4 October 2026).</li>
+          <li><strong>Finality that never pauses.</strong> No. A lock needs two thirds of all 30-day mining weight. Whenever less than two thirds of that weight is connected and signing, finality pauses until it returns or ages out of the window, up to 30 days. The chain keeps running on proof of work and the node reports the pause.</li>
+          <li><strong>A finished protocol.</strong> The sustained-mining finality rule is the newest piece and the one that external review will try hardest to break. The specification, the review and the benchmarks are published as they happen.</li>

Nothing on this chain has been reproduced externally or reviewed independently; every row says so. A label belongs to the exact version in the row, and an audit of one version never covers a newer one. The 12-node cloud network of 4 October 2026 is the project's own, so its rows are tested by the team, not reproduced externally.</p>

+/* The home hero's GPU illustration (7 Oct 2026, from the redesign package's HardwareScene, rebuilt to run continuously).
+ * An illustration, never telemetry: nothing here reads the chain. The loop never idles while the hero is in view: the
+ * fans turn, the pulses travel the traces, the block breathes and drifts, the shards orbit, the lock cage shimmers.
+ * It stops only under reduced motion, a hidden tab or the hero scrolled out of view, and resumes where it left off
+ * (the clock advances by frame delta, never by wall time, so there is no jump on return). The still parts (the grid,
+ * the board, the traces, the card body) are painted once into two cached layers and redrawn per frame with drawImage;
+ * only the moving parts are drawn each frame, so an idle hero costs a few percent of a core at 60 fps.
+ * IgneumHero.mount(canvas, { steps, status, detail }) returns { setStage, destroy }. */

Stated in <code>a repository file</code> section 5.3 (the activate-bound row marked UNMEASURED with the JEDEC figure beside it, and the FPGA paragraph after the table). The epoch-length analysis's 12.2 row is not on master yet and is corrected when it lands.</span></div>
 <details><summary>The answer as first written</summary><p>Correct. The measured 2.4 G/s had been read on 6 October as a mapping artefact (&quot;the paper's point is that this mapping is the wrong one for random access&quot;); the activate window says it is the DRAM's own limit, and a bank-interleaved mapping does not lift it because tFAW is enforced per channel by the die. The measurement that settles it is one AWS F2 hour (f2.6xlarge, Virtex UltraScale+ VU47P, 16 GB HBM2 in 2 stacks, 32 pseudo-channels, USD 1.98 an hour on demand): the chase kernel of <code>a repository file</code> 2.2 ported to a Vitis HLS AXI master over the HBM IP at 1 GiB across all 32 pseudo-channels, 256 to 4,096 lanes in flight, board power at 1 Hz; pass line 15 to 25 M reads/s/W (0.3x to 0.5x of the 5090), alarm 27 (0.5x), over 54 (1.0x) a Counter ASIC 4.0 item. Consequence per tier: none today (no FPGA mines); on the measured row a soft-overlay FPGA mines at an RX 9070 XT's rate per watt for about 7x the price (approximate), so no home or rig tier is displaced.</p></details>

 <details><summary>The answer as first written</summary><p>Correct on both counts, and the second was the sharper one. The X9 (Bitmain, about 1 MH/s at 2,472 W, approximate, github.com/monero-project/monero/issues/10270) is a shipped 3x per-joule edge over a desktop CPU on the best-known latency-bound random-program design, seven years after launch; it makes the k = 0.3 column of the chip model a product class rather than an attacker's claim, and the public headline is now the range 2.1x (k = 1) to 3.9x (k = 0.33) over the RTX 5090 at class v4, with the ladder taking the X9 bracket to about 2.8x by rung 2 and the Apple tier's to about 1.1x by rung 3. The ladder does not close the gap; it is the chain's only automatic answer, it moves at the pace of the cards that pay for it, and the honest card's watts remain the lever that moves every row (algorithm lane proposal 7). What the ladder gives up by design: a chip holding over 10 percent of weight can stall it, and the status quo it stalls is a rung the cards already run.</p></details>

 <details><summary>The answer as first written</summary><p>The fee exists and is disclosed; the rest is wrong in three places. (1) It is software-level, not protocol-level: no consensus rule, coinbase rule or emission rule knows of it. The chain pays whatever payout address a block template names, and the miner software names the dev address for one template in 100. A different client, or the same client with <code>--dev-fee 0</code> (a switch in the app's Settings, <code>DEV_FEE=0</code> on HiveOS), pays nothing and the chain treats its blocks exactly the same. That is the norm for GPU miners (lolMiner, T-Rex, approximate as to their percentages) and the litepaper says so beside the words &quot;the protocol carries no fee&quot;. (2) It is auditable, not hidden: the choice is a template counter, not a random draw. Template n (from 0) is a fee template when floor((n + 1) p / 100) &gt; floor(n p / 100), which at p = 1 is exactly the templates 99, 199, 299, ...; the source is one function (<code>fee_slot</code>, <code>a repository file</code>, section &quot;Software dev fee&quot;), the miner prints <code>dev fee 1% (1 block in 100) to 0x&lt;address&gt;; --dev-fee 0 turns it off</code> at start, logs <code>dev-fee block &lt;hash&gt;</code> for each one and counts <code>fee=N</code> in its status line, and <code>igneum-miner payouts &lt;node&gt;</code> reads the chain back and lists blocks per payout address with the dev address tagged. (3) It takes nothing from anyone else's security: a fee block keeps the user's vote key, so the user's finality weight is unchanged; only the execution-layer payout of that block moves.</p></details>

-        <p class="lead">Igneum is a proof-of-work blockchain built for graphics cards, where NVIDIA cards also prove every block with zero-knowledge proofs and sell proving to other chains. The strongest recompute chip we can price, holding the whole 256 MiB cache on-die, reaches under 1x per chip against an RTX 5090. A memory-controller chip that stores the whole dataset reaches 1.2x per chip and, in our model, 5x to 9x per joule; the Ethash chips of this class reached 2.1x to 4.8x. The lever against it, program work in the latency shadow, is measured and in its gates: it brings the chip to 2.1x to 3.9x, the range running from a chip core as costly per operation as the GPU’s (k = 1) to one as efficient as Bitmain’s Antminer X9 (k about 0.33); the ladder’s second rung takes the X9 bracket to about 2.8x. Sources: the chip model analysis (6 October 2026); the Ethash rows of the ASIC history (Linzhi Phoenix 2020, Jasminer X4 2021, Antminer E9 2022); Counter ASIC 3.0 item 8 (100,000 ops per hash: the chip's per-joule edge over the RTX 5090 falls from 5.6x to 2.1x on GDDR7 at a chip core equal to the GPU's (k = 1) and to 3.9x at the X9’s core (k about 0.33), the 5090 at 0.2% less rate, gates G1 to G6 in progress). The model is public; the claim is tested by paid independent cryptanalysis and the public benchmark.</p>
+        <p class="lead">Igneum is a proof-of-work blockchain built for graphics cards, where NVIDIA cards also prove every block with zero-knowledge proofs and sell proving to other chains. The strongest chip in our public model reaches 5x to 9x per joule against an RTX 5090 today; class v4, now on the vote, brings that to 2.1x to 3.9x, and class v5 makes the dataset the chain’s own state, so a chip that stores it or recomputes it is wrong on every item: <a href="#chip-model">the chip model</a>, every number labelled measured, modelled, claimed or designed.</p>
         <p>It runs the Ethereum virtual machine, so anything built for Ethereum runs on Igneum unchanged. Transactions are included in about one second, proven within about a minute at launch, and locked by miners within about two. There is no premine, no pre-sale, no treasury taken from emission, no stake anywhere in consensus, and no dependence on any other chain. Mining stays open to anyone with a GPU because the mining program changes every hour, so a chip built for one program is useless for the next, and a chip for the whole program space is a GPU without the graphics parts. No scheduled human release is needed to keep it that way. Writing new code, including an emergency fix to the proof system, is the one thing that takes a person, and it activates only on miner signalling.</p>

         <p>Three ideas carry the chip resistance. <strong>The hash rewrites itself.</strong> A new program every hour, drawn from the chain. Its memory pattern changes with it. The rules change on a schedule fixed at launch. No release, no vote. These are automatic schedule changes: they defeat a chip wired for one datapath and they need no human fork. Against a chip that stores the dataset every drawn parameter is firmware, and what meets that chip is the latency-shadow work (class v4) and the price per joule (the Horizon lane analysis, 6 October 2026, section 5.4; ledger M32). <strong>It waits on memory, not maths.</strong> Every hash is a chain of random reads into a table too big for a chip to carry. The wait is the same physics for everyone. <strong>Miners hold the switch.</strong> Spare defences are written into the rules, switched off. A miner signal turns one on, at the class-change threshold: miners signal three things at three thresholds, 60 percent of blue blocks over two weeks for a parameter genesis leaves open, 90 percent for an upgrade (new code), and 95 percent with a floor height for a class change. No fork.</p>
-        <p><strong>The work that waits can grow.</strong> Class v4 adds a block of latency-shadow arithmetic to every hash, about 100,000 integer operations that run while the memory reads are in flight, so a chip that stores the whole dataset still has to pay for a core. That size sits on a ladder fixed at genesis, six rungs from about 100,000 to about 1,000,000 operations, and it moves one rung at a time only when 90 percent of blue blocks in each of seven consecutive days ask for it; it can never move two rungs inside a week and never past a rung the reference verifier cannot check under 10 ms with its sibling thread busy (measured on the build server, 6 October 2026: the first three rungs pass at 8.8, 8.9 and 9.2 ms, the fourth misses by 0.08 ms on a loaded box and stays out until a quiet re-measurement, the two doublings are out at 12.4 and 15.0 ms). What it buys, on the measured cards: against a dataset-storing chip whose core costs what an RTX 5090's does per operation, the chip's per-joule edge falls from 2.1x at the first rung to 1.3x at the third; against a core as good as the shipping RandomX chip's (Bitmain's Antminer X9, about 3x per joule over a desktop CPU after seven years, approximate), from 3.9x to 2.8x. What it costs, per rung, is measured too: the Apple tier gives up 3 points of rate at the first step and 6 more at the second, the RTX 5090 nothing until the second; so the miners who pay for a step are the ones who take it (<a href="/ledger#M34">ledger M34</a>).</p>
-        <p><strong>The dataset is the chain.</strong> Class v5 builds each hour's dataset from the chain's own execution state at that hour's reference block: every account, every storage slot and every byte of contract code, hashed under the state root and folded into every item. A card that does not hold the state cannot build the dataset, and a card that builds it from stale state is wrong on every hash from the next refresh on, so a miner must keep following the chain to keep mining. The hash itself does not change, and neither does its speed: measured on an RTX 4090 on 6 October 2026, 63.08 against 63.09 million hashes a second at 207 W, the hourly rebuild 32 ms, a node's check 0.1 to 0.2 ms longer per block. What it buys is a floor under what mining means: a chip that recomputes items instead of storing them must now hold the state too, and a pool miner who today needs nothing but the date needs the state every hour. What it does not buy is stated as plainly: a pool or a farm with one node can ship the state to its cards each hour, 6 KB today and at most 2 GB on a used chain, so the claim is that every mining operation holds and follows the chain, not every card; and against a chip that stores the whole dataset it changes nothing, which is why it sits beside the latency-shadow work, not in its place. It ships switched off, behind the 95 percent class signal with a floor height (<a href="/ledger#M35">ledger M35</a>).</p>
-        <p>No hash has stayed free of chips forever. Igneum does not claim to. It states the gain its own model finds, the response takes a week, and both are measured. The model is public: <a href="/bench#counter-asic-2-0-the-numbers">the numbers</a>; the claim is tested by paid independent cryptanalysis and the public benchmark. Monero ran on RandomX from 2019 (approximate) with no chip publicly shipped until Bitmain’s Antminer X9 in July 2026 (1 MH/s at 2,472 W, about USD 5,600; monero-project/monero issue 10270). About seven years of hold and then a chip: that is the record Igneum’s hourly program and its chip model are built against.</p>

The ladder that sets how much work rides in the shadow starts at rung 0 at the testnet genesis and climbs by miner signal; its third rung is inadmissible today because a server core verifies it in 10.85 ms, over the gate (measured, 7 October 2026). The next test of the model is not ours: the cryptanalysis plan buys three external lots against the mixer, the chained cache and the acceptance rule.</p>
+        <p>No hash has stayed free of chips forever. Igneum does not claim to. It states the gain its own model finds, the response takes a week, and both are measured. The model is public: <a href="/bench#counter-asic-2-0-the-numbers">the numbers</a>; the claim is tested by paid independent cryptanalysis and the public benchmark. Monero has run on RandomX since 2019 (approximate) with no chip shipped. Bitmain opened Antminer X9 pre-orders on 26 December 2025 for July 2026 delivery, then withdrew the product in mid-May 2026 and refunded buyers before any unit shipped; none has been independently benchmarked. A box with about a 2x per joule edge over the best CPUs, and about 3x over a desktop, was withdrawn rather than face a RandomX re-tune of 1.5x or more. That is the band Igneum’s class v4 model sits in (2.1x to 3.9x over an RTX 5090), and the defence that held was a maintained algorithm with a credible upgrade path, which is what the ladder is.</p>
         <p>One thing takes a person, here and on every chain that exists: writing new code. A chain cannot safely write its own generator, and it cannot safely tell a chip from a wave of honest new cards by hashrate alone. If the design above ever failed, anyone could publish a new generator and miners would switch it on by signalling, as Monero's community can fork. Igneum is built to make that day unlikely, and does not depend on avoiding it.</p>

         <p>Measured so far: the same hourly program, generated on an Apple M5 Max, compiled by Apple's Metal and NVIDIA's CUDA on an RTX 5090, produced identical hashes on both, 192 of 192 across two programs. On a 1 GB dataset the 5090 ran at about 228 million hashes a second and the Mac at about 45 million, both bound by random memory access rather than arithmetic. Those are prototype figures, not mining rates. The first prototype dataset was a closed-form function, and a miner could compute items instead of loading them: measured 111x faster that way on the Mac. The 256 MB cache construction replaced it on 3 October 2026. With the cache, computing items on the fly runs 4.8x slower than loading them, measured on the Mac, and the honest rate is unchanged on both vendors. Open: the same shortcut ratio on NVIDIA and on a discrete AMD card, and the time-memory trade-off between the two measured points. Inside the 5090's 96 MB cache the same program ran nearly six times faster, which is why the dataset starts at 2 GB and grows. On 4 October 2026 the live devnet crossed an hourly program change on all three vendors with no pause and no rejected block: a Mac at 26.7 million hashes a second, an RTX 5090 at 123 million and an integrated AMD chip at 2.7 million, every hash doing 128 distinct reads of the memory-hard dataset.</p>

         <h3>No fund, no foundation, no fee to the team</h3>
         <p>There is no development fund. A switch that routes money to an address somebody controls is the first thing a critic points at, so Igneum has none. The protocol carries no fee to any team, foundation or fund. The project earns in the open, and this is the full list: the optional 1% dev fee in the Ember miner software, off with one flag and audited on the chain; the provers it runs in the job market; any pool it operates; and the app share on the contracts it deploys, like anyone else. None of it is in the protocol, and the first item is the one a critic should quote: for as long as miners run Ember with the fee on, 1 block in 100 pays the project. If the community ever wants a grant mechanism, miners can add one by signalling.</p>

+        <p>A block pays its miner whether or not anyone buys a proof that day. The lottery pays 80 percent of every block from emission; proving is the second income, never the only one. Every useful-work chain on record dropped its miners the day the work stopped paying; Igneum’s miners are paid for the block first.</p>
         <p>The size of that third stream today, in numbers: all of Ethereum L1's proving is about USD 36 a day at the September 2026 tracker cost (USD 0.005 a block, 7,200 blocks a day; the tracker figure is a secondary source), against about USD 13,700 a day of Igneum's year-1 emission at USD 0.005 per IGN (31.688 IGN a block, 86,400 blocks a day; the price is an input, not a forecast). So external proving is a small second income at launch and the lottery pays the bills; for proving to become the main income the paid demand would have to grow about 1,000x in dollars (the Horizon lane analysis, 6 October 2026, section 3.11; ledger E19).</p>
         <p>The honest bear-market case rests on cost. A miner's card is already running and the power is often domestic, so Igneum miners' electricity cost in the proving market is close to power. The price they must charge is another matter: the price a prover must charge is the subsidy it forgoes while it proves, which falls as one over network hash, so the edge over data-centre provers appears only once the network's hash is large (near 100 GH/s for a card proving beside its miner) and is nothing more. Which of the two in-chain streams pays more per GPU-second depends on the size of the fleet: on the devnet of 4 October 2026, three machines at 275 million hashes a second, a second of hashing paid about 4.9x a second of proving the pool share; at 10,000 cards the same arithmetic favours proving by about 930x. That is arithmetic on measured devnet rates, approximate, not a market measurement.</p>

-/* Igneum live DAG view (docs/plans/site-ui-3.md section 6, 6 October 2026).
-   One module for /live and the home page. Reads /api/live only; every pixel is a block, edge or checkpoint the observer
-   stored. Blocks are placed by header time on x (the axis is labelled in DAA score) and by miner lane on y. Parent edges
-   are drawn; the edge between two selected-chain blocks is heavier and the chain glows as one path. Colour words are the
-   ledger's: pending, included (blue), excluded (red), proven (every shard verified or paid), locked (a checkpoint block).
-   Checkpoints are vertical bands at their blue score with the lock weight; a locked band is solid, a pending one dashed.
-   The view scrolls at chain speed, new blocks arrive from the right with a brief glow. The page's scroll passes through the
-   scene; zoom takes ctrl or cmd with the wheel, a pinch, or a click into the scene (engaged, released by Escape or a click
-   outside; opts.chip is the "scroll to zoom, Esc to release" element); window 30 to 300 s (the API's ?window=); a pause button;
-   hover and tap show a block's details.
-
-   Usage: var dag = IgneumDag.mount(canvas, { compact, window, url, poll, mine, onState, onData, onWindow, onEngage, pauseButton, tooltip, chip })
-   - url: the /api/live endpoint (default '/api/live'); poll: false stops the module's own 2 s fetch, the host then calls
-     dag.push(reply) with a reply of the same shape ({ok, state:{stale, age_s, height, ...}, blocks:[...], finality:{checkpoints:[...]}, proving})
-     whenever it has new data (every poll or every new block, either is fine; blocks already on screen are updated in place).
-   - block record (the /api/live shape): hash (string, 16 hex), ts (ms, header time), blue_score, daa (numbers), parents ([hash]),
-     chain (bool, selected chain), color ('blue' | 'red' | 'pending'), miner (string lane key, 8 hex of the vote key hash),
-     locked (bool, a locked checkpoint block), final (bool, at or before the newest lock), shards ([{state: 'planned' | 'proving' |
-     'verified' | 'paid'}]), proven (bool, every shard verified or paid). Checkpoints: {index, blue_score, state: 'locked' | 'pending', fraction_total}.
-   - mine: a miner lane key (string) or function(block) -> bool; the user's own blocks take a molten ring and the lane is labelled "you".
-   - The legend is the host's; the module draws no HTML. Colours come from the CSS custom properties on :root (--ember, --ember-hi,
-     --molten, --bone, --ash, --line, --line-2, --row or --obsidian), re-read on data-theme and prefers-color-scheme changes.
-   - Sizing: the canvas fills its CSS box (width and height from the stylesheet); 280 px wide works, 600 or more shows lane labels well.
-   onState(state, reason): 'connecting' | 'live' | 'stale' | 'failed'; onData(d) with every fresh reply. */

-    <p>A node is read every two seconds. Every block below is real: its parents, its miner, whether it sits on the selected chain, and whether it is a locked checkpoint. A checkpoint locks when the finality rule's quorum signs it. Once the proving layer is activated, every chain block's shards show as they are planned, proven and paid.</p>
-    <p>Fees: from DAA score 210,000 (the chain's block-time clock, about one step a second) the adopted fee table applies: 300 proving gas per transaction, 30,000-gas shards, floors of 100 gwei per gas and 10,000 gwei per proving gas. Before it the devnet metered with its prototype table, and the provers' program carries both.</p>

 <p class="note">Igneum runs the Ethereum virtual machine, so MetaMask and every other Ethereum wallet work unchanged. The wallet needs four things: the chain id, an RPC URL, the symbol <b>IGN</b> and <b>18</b> decimals. The button below sends them to the wallet with the standard <code>wallet_addEthereumChain</code> request; the wallet shows them to you and asks before adding anything. Nothing on this page asks for a seed phrase or a key. Nobody from Igneum will ask for your seed.</p>

+      <details><summary>Does my card mine and prove?</summary><p>Every card mines. Proving the full shard needs a 24 GB NVIDIA card; a 32 GB card does both at once. Apple silicon proves on the CPU, slowly. The Prove page of the app says in one sentence what your card can do.</p></details>
+      <details><summary>Is the devnet paying real money?</summary><p>No. Devnet coins have no value and the chain may reset. The app’s pounds row reads 0.00 on devnet and says why. The public testnet opens when the go checklist closes; mainnet comes after the testnet passes its gate.</p></details>
+      <details id="fee-faq"><summary>Is there a fee?</summary><p>Not in the protocol: no dev fund, no fee to any team. The app takes an optional 1% software fee, the norm for GPU miners, and one flag turns it off. <a href="#fee">The fee, in full view.</a></p></details>
+      <details><summary>Can I run it on a rig or in a pool?</summary><p>The Linux and HiveOS tarball is above, with the flight sheet. Pools are part of the public testnet; until then every machine mines solo on its own keys, and a card runs several.</p></details>

 <p>Every row names the engineering log entry or the job it came from. "Measured by the team" means our own hardware and our own log. "Reported by the fleet" means a machine we do not own, read from the status lines its miner uploads.</p>
 <p>MH per watt needs the card's power draw during the run. The app reads it on NVIDIA cards through the driver. Rows get the figure when a run records it.</p>
 <p>There is no other Igneum miner to compare with yet, so this table compares cards, not miners. The app that produces these rows: <a href="/miner">the miner page</a>.</p>
 <p>Rows: 6. Each row names the engineering log entry it came from.</p>
-<h2 id="priors">Fleet tuning priors</h2>
+</section>
+<section class="doc-section"><h2 id="priors">Fleet tuning priors</h2>
 <p>Ember Tune runs on every card the app mines with: the power limit and the core clock are stepped on the live program and the card keeps the point with the best MH per watt within 1% of its top rate. Every finished tune is reported back without anything that identifies the owner, and the fleet's median point per card model, driver major and program class comes back down inside the signed update manifest as the starting point for the next card of that model. A model needs 5 reports before its prior is used.</p>
 <p>No tune reports yet. The first rows appear once five machines with the same card model have reported.</p>

+<p>Decision of 3 October 2026. Igneum credits every borrowed component in public, replaces only what its own design requires, and measures every change. This table is the public record of that decision. It is kept current with <code>docs/fork-divergence.md</code> (the node fork, change by change) and <code>docs/bench-log.md</code> (every measurement with its command).</p>
+<p>How to read the licence column. "Verified" means the LICENSE file or the crate's <code>Cargo.toml</code> was read in this repository on 3 October 2026. "Approximate" means the licence is stated from memory because the source is not cloned under <code>vendor/</code> yet; it is checked again when the clone lands, and before the repository goes public.</p>

+<div class="tbl"><table><thead><tr><th>Component</th><th>Origin (project, licence, repository)</th><th>What Igneum changed</th><th>Why the design needs the change</th><th>How the change is measured</th></tr></thead><tbody><tr><td>GHOSTDAG ordering</td><td>Kaspa, rusty-kaspa. ISC, verified (<code>vendor/rusty-kaspa/LICENSE</code>, "Copyright (c) 2022-2024 Kaspa developers"; workspace <code>license = "ISC"</code>). https://github.com/kaspanet/rusty-kaspa</td><td>Unchanged algorithm. Parameters set for 1 block per second: k 18, 10 max parents, mergeset limit 180, merge depth 3,600 blocks (<code>consensus/core/src/config/bps.rs</code>, <code>params.rs</code>)</td><td>Launch rate is 1 block a second (the design document), rising later. These are the values Kaspa mainnet ran before Crescendo, so nothing new is asserted about the ordering</td><td>Spec section 2.1; bench-log "igneum-node devnet v0: 3-node igneum-devnet at 1 BPS"; a test in <code>params.rs</code> pins every value</td></tr><tr><td>Node software (the fork)</td><td>rusty-kaspa v2.1.0, commit <code>01b532e8</code> (22 Sep 2026). ISC, verified. Fork at <code>vendor/igneum-node</code>, one commit per change on top of the base</td><td>Header gains <code>vote_key_hash</code>; genesis blocks; network ids <code>igneum-*</code>; devnet ports; DNS seeders emptied; address prefixes; emission schedule and 80/20 coinbase; PoW engine trait; PoW check moved after GHOSTDAG; rename of every user-visible string to <code>igneumd</code>. Full list: <code>docs/fork-divergence.md</code></td><td>Each row there states the reason. The short version: finality rule v2 needs a vote key in every header, the emission is Igneum's own, the lottery hash needs chain state, and no Igneum node may ever dial a Kaspa peer</td><td><code>docs/fork-divergence.md</code> (file, change, why, risk, merge note per row); bench-log devnet v0 and "first devnet blocks on the real lottery hash" entries; the four-node rename test of 3 Oct 2026</td></tr><tr><td>Difficulty controller</td><td>Kaspa sampled DAA (KIP-4) in rusty-kaspa, ISC, verified, kept as the retarget. Prior art studied: LWMA by Zawy (zawy12/difficulty-algorithms, licence approximate: MIT) and Monero's sorted and trimmed window (monero-project/monero, approximate: BSD-3-Clause). No code from either</td><td>Unchanged in the fork today (comment block only, <code>consensus/core/src/config/constants.rs</code>). The hash speed steps at every hourly program change, so a rule that tracks a step within an epoch is in progress: a two-speed rule (fast response to a step, slow drift otherwise). Not in spec 0.1</td><td>Programs differ in cost (35 to 48 Mhash/s across seeds on one GPU), so a 44-minute window spends half an epoch at the wrong block rate</td><td>Spec section 2.3 names the two remedies and the gate 2 simpa run that decides; bench-log first-run and RTX 5090 entries hold the per-seed rates. The two-speed rule gets its own bench-log entry when it is simulated</td></tr><tr><td>Random-program idea</td><td>RandomX by tevador, Monero. Licence approximate: BSD-3-Clause. https://github.com/tevador/RandomX (not yet cloned under <code>vendor/</code>; the design document asks for it)</td><td>The idea only. Igneum's generator is new code (<code>igneum-pow/src/generator.rs</code>): a program drawn once per hourly epoch and compiled to native GPU code, with a per-hash random data path. RandomX draws a program per hash and interprets it on a CPU</td><td>A GPU cannot interpret a fresh program per hash at a useful rate; it compiles one program per hour instead. The target hardware is the opposite of RandomX's by design</td><td>Spec section 1 (generator, test vectors); bench-log "proto-metal first run", "RTX 5090 first run", "igneum-pow bit-exact" (96/96 vectors, three GPU vendors)</td></tr><tr><td>Memory-hard dataset</td><td>RandomX cache lineage (tevador, BSD-3-Clause approximate): a small cache that derives a large dataset by dependent reads</td><td>New construction, same shape: 256 MiB cache of chained ChaCha12 blocks, 8 dependent reads per item, dataset 1 GiB in the prototype and 2 GB at genesis, growing on a genesis-fixed schedule (<code>igneum-pow/src/memhard.rs</code>, <code>proto-metal/MEMHARD.md</code>)</td><td>A light verifier must hold only the cache; a miner must hold the dataset; the dataset must outgrow any fixed chip memory. RandomX's dataset has one size for ever</td><td><code>proto-metal/MEMHARD.md</code> section 2.2 (recompute 4.8x slower than load, Apple only); bench-log "memory-hard dataset" entries on Metal and the RTX 5090</td></tr><tr><td>ChaCha, SplitMix64, FNV-1a inside the lottery hash</td><td>ChaCha by D. J. Bernstein (public domain, approximate); SplitMix64 by Steele, Lea and Flood (algorithm from the 2014 paper, approximate); FNV-1a by Fowler, Noll and Vo (public domain, approximate). All three re-implemented from the definitions in <code>igneum-pow</code>, no code imported</td><td>Used as published: ChaCha12 core with feed-forward for the cache fill, SplitMix64 as the program stream, FNV-1a 64 for seed words and the cache digest</td><td>Standard, well-studied primitives for a cache fill and a seed stream; nothing in the design asks for more</td><td>Spec sections 1.3 and 1.8 with test vectors; bench-log "igneum-pow bit-exact" (cache digest <code>48c4f5bf24166b2e</code> matches Swift and C++)</td></tr><tr><td>ProgPoW and KAWPOW</td><td>ProgPoW (EIP-1057 text, ifdefelse/ProgPOW; KAWPOW on Ravencoin since 2020, RavenProject/Ravencoin, MIT approximate). Prior art, no code used. Not yet cloned; <code>docs/fud-fixes.md</code> item 48 asks for the clone and citation before the repository is public</td><td>Nothing taken. The difference: ProgPoW and KAWPOW randomise the maths inside a fixed program shape every few blocks; Igneum regenerates the whole program every hour over a growing dataset, with automatic era draws and no human in the loop</td><td>Stated so that the "first" claim in the litepaper is accurate (FUD ledger M4)</td><td>Litepaper "What has never been done before", row 1, rewritten 3 Oct 2026</td></tr><tr><td>Class-group VDF</td><td>Chia, chiavdf. Apache-2.0, verified (<code>vendor/chiavdf/LICENSE</code>), commit <code>7e62ce14</code>. Wesolowski's proof (Efficient Verifiable Delay Functions, EUROCRYPT 2019), a paper, no licence</td><td>NUDUPL and NUCOMP ported from chiavdf's <code>qfb_nudupl</code> and <code>qfb_nucomp</code> into <code>proto-vdf</code> (Rust, over GMP through <code>rug</code>); fresh 1024-bit prime discriminant per input; 256-bit Fiat-Shamir prime (Chia uses 264); Igneum tags for the epoch and era paths. The textbook composition is kept as an oracle</td><td>The program seed must come from a certified checkpoint with a delay no miner can skip, so the seed cannot be ground. Chia's group needs no trusted setup</td><td>Spec section 4.2 (15,000 random cases agree with the oracle; 163,000 squarings per second; 4.5 ms verify); bench-log "proto-vdf" entry. GMP itself: LGPL-3.0 or GPL-2.0 dual, approximate, prototype only; the production dependency is decided with the wire format (O-4.5)</td></tr><tr><td>revm</td><td>Ethereum ecosystem, bluealloy/revm. Licence approximate: MIT. https://github.com/bluealloy/revm (not yet cloned)</td><td>Unchanged, credited. Driven by an Igneum block executor that feeds it the DAG's canonical sequence with the environment table of spec 7.1 and two-dimensional gas</td><td>The same EVM runs natively and inside the zkVM (reth, rsp and SP1 Reth all use it), so native and proven execution share one code path</td><td><code>docs/design/execution-layer.md</code> D6 and section 2.1; differential test plan against reth (section 8.5). Nothing measured yet</td></tr><tr><td>SP1-class provers</td><td>Succinct, succinctlabs/sp1. Licence approximate: MIT or Apache-2.0. Not yet cloned</td><td>Unchanged, behind the versioned <code>ProofSystem</code> trait (<code>docs/design/execution-layer.md</code> 5.6). Version 1 is SP1 (Hypercube class, hash-based). Devnet v1 runs a stub that signs claims</td><td>Consumer cards prove hash-based systems without elliptic-curve MSM; the trait makes a swap a release (90% signalling, 3-month overlap, one wrap), never a redesign</td><td>No SP1 shard has been proven on any card in this repository (FUD ledger P1, P3). Phase 2 gate: shard time on a 3060-class card, published pass or fail</td></tr><tr><td>BLS12-381</td><td>Curve by Barreto, Lynn and Scott; blst by Supranational. Licence approximate: Apache-2.0. https://github.com/supranational/blst (not yet cloned)</td><td>Unchanged, credited. The header carries the BLAKE2b hash of a G1 compressed public key (48 bytes); every voter signs every 30-s checkpoint; signatures aggregate</td><td>Finality rule v2 needs one aggregate signature per checkpoint from thousands of keys</td><td>Spec section 3.1 (W1) and 2.4; <code>sim/results_v2.md</code> for the rule itself. Signature cost not yet measured</td></tr><tr><td>Hashing in the node</td><td>rusty-kaspa <code>crypto/hashes</code>, ISC, verified. Crates linked by the fork, licences read from the local cargo registry: blake2b_simd 1.0.2 (MIT), blake3 1.8.3 (CC0-1.0 or Apache-2.0), sha2 0.10.8 (MIT or Apache-2.0), keccak 0.1.6 (Apache-2.0 or MIT); sha3 0.10.8 not in the local registry, approximate: MIT or Apache-2.0</td><td>Unchanged, credited.

+        <p>Measured so far: the same hourly program, generated on an Apple M5 Max, compiled by Apple's Metal and NVIDIA's CUDA on an RTX 5090, produced identical hashes on both, 192 of 192 across two programs. On a 1 GB dataset the 5090 ran at about 228 million hashes a second and the Mac at about 45 million, both bound by random memory access rather than arithmetic. Those are prototype figures, not mining rates. The first prototype dataset was a closed-form function, and a miner could compute items instead of loading them: measured 111x faster that way on the Mac. The 256 MB cache construction replaced it on 3 October 2026. With the cache, computing items on the fly runs 4.8x slower than loading them, measured on the Mac, and the honest rate is unchanged on both vendors. Open: the same shortcut ratio on NVIDIA and on a discrete AMD card, and the time-memory trade-off between the two measured points. Inside the 5090's 96 MB cache the same program ran nearly six times faster, which is why the dataset starts at 2 GB and grows. On 4 October 2026 the live devnet crossed an hourly program change on all three vendors with no pause and no rejected block: a Mac at 26.7 million hashes a second, an RTX 5090 at 123 million and an integrated AMD chip at 2.7 million, every hash doing 128 distinct reads of the memory-hard dataset.</p></div>

+// IGNEUM_PROJECT_POOLS (comma-separated IGNA addresses) so the report can mark pool-0 as the project's.
+//
+// Definitions (ledger-decisions.md section 3, X5; CLAUDE.md finality rule: dust = 100 blocks in the 30-day window):
+//   a key "with a block" found at least one blue block in the window; "above dust" found 100 or more blue blocks in the

+//   is a pool OR one machine running several identities to one address (the devnet default until decision 13 of
+//   ledger-decisions.md lands), so a shared payout counts as a POOL only when it is attested: the project's own pools
+//   (IGNEUM_PROJECT_POOLS) or an outside pool whose operator published the signed key list X5 asks for
+//   (IGNEUM_KNOWN_POOLS); "fleet" is a key one of the project's intake-reporting workers logged (miner_logs) or one listed
+//   in the fleet registry's key file (IGNEUM_FLEET_KEYS_FILE, one 64-hex key per line: the rented boxes do not upload
+//   identity lines, so without the file the devnet reads its own fleet as outside); "outside" is everything else.
+//   The independent-key count (X5: autonomous system, machine fingerprint, pool attestation) needs two observer columns
+//   that do not exist yet; the report prints the keys above dust as the upper bound and says the columns are owed.

+`engine.js` is the full-site redesign package's observer adapter as delivered on 7 October 2026 (the `/api/live` contract
+validator, the read-only `Feed` with its backoff, and the package's explicit sample generator). The served site does not
+load it: the pages use `site/scenes/feed.js` and `site/live-dag.js` 2.0.2, which normalise the observer reply themselves,
+and no sample data is served anywhere. The file is kept here, unserved, so the package's contract tests keep running in
+the gate (`tools/ci/pre-push.sh`: "redesign package data tests") against the `/api/live` shape the site depends on.
