Shadow block compressibility and shortcut search (hash lane) + +Method: over 10^4 class v4 programs, constant folding, dead-register elimination, common subexpressions across the +27 repetitions, linear sub-block detection, SAT equivalence on reduced blocks; the minimum op count per program +against N. Known-failed shape: a shadow that constant-folds or dedupes across its 27 identical passes so a chip +pays fewer than 55,296 shadow instructions per hash. Entry point: `igneum-pow show --program-class v4` prints the +256-instruction shadow (op mix add=47 rotl=30 xor=30 shfl=29 mad=27 mul=22 sub=21 rotr=20 mulhi=18 or=12 on the +genesis seed). Gate: best compressed block within 5% of N on every program; no program over 10% compressible. +Result: RUNNING. What a failure moves: an acceptance-rule line for the shadow block (rule (c) runs the block), +packs re-cut. + +### F2. Mixer round margin (hash lane, on the box) + +Method: SAT or MILP differential and linear search on 1 to 4 keyed applications with drawn rotations; rotational-XOR +on the ARX layer; the fold of the multiply layer across applications checked algebraically. Known-failed shape: a +differential or linear trail or an algebraic fold that distinguishes or shortcuts more than 2 of the 8 applications +between dependent reads. Gate: no distinguisher or shortcut beyond 2 of the 8 applications. Result: RUNNING (prior +`ca2-mixer` evidence to be re-gated). What a failure moves: `mixer_mult` 16 or a shape change; verifier re-measured. + +### F3. Chained cache j+1 bound and storage-vs-recompute curve (hash lane, on the box) + +Method: exhaustive search on a 2^10-line model segment for a line derivable without an earlier line; the curve from +f = 1/64 to 1 in ops per item. Known-failed shape: a line (s, j) computable in fewer than j+1 block evaluations +without an earlier line (the MTP address-steering break shape). Gate: no derivation under j+1 blocks; curve monotone; +f=1 point unchanged. Result, 7 October 2026, 09:10 to 09:12 UK on the box (`docs/analysis/attack-pass/f3-cache.md`; logs +`/srv/builds/igneum-wt-attack/attack-f3/r1-*.log`): PASS on all three clauses. The chain extracted from +`Cache::fill_segment` (verified equal to the code on 16 of 16 key and segment pairs; `block == chacha_block` on +100,000 random inputs) has line j fed by line j - 1 only; the exhaustive closure search finds 0 of 64 and 0 of +1,024 lines under j + 1 (every line costs exactly j + 1), cross-checked by an exhaustive pebbling search at 10 +lines (10,240 configuration and target pairs, 0 mismatches). The two planted chains fire: `skip2` (63 of 64 under +j + 1) and `nofeed` (every line in 1 block). The curve over stored cache lines is monotone non-increasing from +f = 1/64 to 1 at 608 (counted) and 700 (MEMHARD.md) ops per block; the f = 1 point is 9,360 ops per item, +41.7 MH/s at the 50 T op/s budget, unchanged. `ca2-cache` was the hot-table experiment, not a chain analysis, so +there was nothing to re-gate. Observation (coordinator and the F3 record, not a finding): `funding.md` B2 rank 2 +prices the trade-off at the naive placement; the optimal placement of every 8th line costs 3.17 blocks per read, +not 3.5, and 16.0 at f = 1/64, not 31.5 (brute force over 4,426,165,368 sets at n = 8); the chip stays worse than +the full mirror at every f under 1, so the verdict stands, and a `chacha_block` shortcut in chaining mode stays +the open question of the adversarial lanes. What a failure would have moved: the chain construction (a second feed-forward or +a cross-segment tie). + +### F4. Weak-day census over 2^24 day keys (hash lane, on the box) + +Method: 2^24 day keys through `MixParams::with_shape`; the ROT classes (all equal, complementary pairs, small +amounts), MUL low weight, RC structure, each per-day gain measured on the box verifier. Known-failed shape: a day +key whose drawn ROT/MUL/RC gives a fixed datapath a gain over 1.1x (the "weaker authorized parameters" class, +Kudelski 2019). Gate: the fraction of days with any gain over 1.1x under 2^-20. Result: RUNNING. What a failure +moves: a rejection-and-redraw rule on the draws. + +### F5. Chip-model sweep and the FPGA hour (algorithm lane) + +Method: `sim/horizon/algorithm/model.py` over k 0.2 to 1.5, tFAW 12 and 28 ns, HBM4 2.3 and 21.4 G reads per +stack, amortisation 1 to 3 years, electricity USD 0.05 to 0.15 per kWh; and the AWS F2 hour replacing the FPGA +ceiling row with a measurement. Known-failed shape: an input of the published model that, when corrected, lifts the +f=1 chip's per-joule edge over the 5090 above the published 2.1x at k=1. + +Gate: the published sentence (evidence row 17) holds across the sweep; the FPGA row under 27 M reads/s/W. + +Result (sweep): PASS on the numbers. The model's measured-anchor column (GDDR7, the 5090 reads 82% of its ceiling) +gives the f=1 chip's v4 per-joule edge over the RTX 5090 bench row as 4.1x / 3.2x / 2.1x / 1.5x at k = 0.3 / 0.5 / +1 / 1.5. At k = 1 the figure is 2.1x, and 3.9x at k about 0.33, which matches `fud-ledger.md` M32. The higher HBM3 +and HBM4 columns rest on an 8-activate per 12 ns window that JEDEC HBM2 timings (4 per 28 ns) do not support; the +model already states GDDR7 is the column to quote. One wording gap: `evidence.md` row 17 says "brings it to about +2x", which is a floor that holds at k about 0.9 and above but understates the edge at lower k (3.2x at k = 0.5). The +accurate statement is M32's, 2.1x at k = 1 with the k range beside it. The sweep's numbers stand; the finding is the +X9 framing below. + +FPGA row: the HBM2 FPGA ceiling is 2.3 to 2.9 G reads/s (measured Shuhai U280, FCCM 2020, equal to the JEDEC +tFAW-bound 2.3 G/s), 10 to 21 M reads/s/W at 115 to 150 W, 0.30 to 0.47x of the 5090 per watt. Under the 27 M +reads/s/W gate. The AWS F2 hour is SKIPPED-BY-DECISION (the founder, 7 October 2026, 09:5x UK: not needed for now, not blocked; +plan 4.2 row F5 at commit 3714c2a0 on branch cryptanalysis is the chip-model sweep only, 4 h, the algorithm lane). +There is also no AWS account or `aws` CLI on this Mac. The FPGA row stays the JEDEC-ceiling model row labelled +unmeasured; the chip-model lane prices it from the reads-in-flight model; the public report states that the F2 measurement was not run. + +FINDING (X9 framing), owning lane algorithm and hash (the ladder lane is closed, so ours): the published numbers +already carry 2.1x at k = 1 beside 3.9x at k about 0.33 (`fud-ledger.md` M32, recalibrated under X35). The error is +the framing. M32 calls the k = 0.33 figure "the X9's core" and the `ladder` branch's `latency-ladder.md` section 5a +calls k about 0.33 a "measured class". Bitmain's Antminer X9 (RandomX ASIC, 1 MH/s, 2,472 W, about USD 5,600) was +announced and, per pcpraha.cz ("Antminer X9 canceled: Bitmain withdraws model from market before launch") and +r/MoneroMining, withdrawn before launch. Its implied core efficiency (k about 0.33) is a CLAIMED datasheet figure +from a design that never shipped and was never benchmarked, not a measured calibration point. It is carried as the +pessimistic bound, not a calibration. This collides with the merged ledger X34 ("RandomX has a shipping chip; +correct every sentence that said otherwise"): if the X9 was withdrawn, X34's correction is itself wrong and must be +reversed. Confirmed from primary sources (coordinator, 7 October 2026): pre-orders opened 26 December 2025 (shipments +scheduled for July 2026), withdrawn in mid-May 2026 with buyers refunded before any unit shipped, no independent +benchmark, Bitmain never published a cancellation (its shop lists it as sold out), and the box was commodity Sophgo +SG2044 server SoCs with an AES accelerator and 60-plus DRAM sticks, no tapeout; its claimed edge about 2x per joule +over a tuned Zen 4 part, about 3x over a stock desktop CPU. Re-cut applied the same day: `evidence.md` row 17 (claim +and measured cells) and `fud-ledger.md` M32's answer paragraph on attack-pass, and the ladder design doc section 5a +on branch `attack-ladder-5a` from the ladder tip 7003f9f5 (the `ladder` branch is checked out by another lane, so +the fix rides its own branch for the ladder owner to take). The served-text rows (X34 reversal, X36) belong to the +site lane, which confirmed the wording agrees. What a finding moves +(plan 4.2 F5): the sentence re-cut before the freeze so the public report carries the corrected model. The re-cut, once the +fact is confirmed: k about 0.33 labelled a claimed pessimistic bound from a withdrawn design everywhere it appears; +2.1x at k = 1 on the GDDR7 measured anchor kept as the headline with the k range beside it; k itself unmeasured +until the chip-model lane produces it. This row reads FIXED-AND-PASSED only after the re-cut and its re-gate. + +Economic row the withdrawal implies: a recompute chip at a 3x fixed-function factor against a CPU and GPU fleet +must recover its NRE (low to mid seven figures at a modern node, `chip-model-v3.md`) and carry a fork threat (a +class change at 95% miner signal can redraw the datapath the chip bakes in). The X9 at 2.47 J per KH against a +RandomX CPU fleet did not clear that bar at Monero's hash and price; the same arithmetic against Igneum's class v4, +with the shadow block and the automatic era draw as extra firmware risk, is why the chip model's verdict is a +deliverable and not a courtesy (plan 2.3). The confirmed reading: a box with a 2x to 3x per-joule edge and no NRE (commodity SoCs) was withdrawn rather than +face a 1.5x re-tune of RandomX, so the tapeout economics of a 3x chip against Igneum are worse than the X9's. This +row is the pessimistic case, not a measured gain. + +### F6. Verifier worst case (algorithm lane) + +Method: 10^5 class v4 programs timed on the box one-core and half-core proxies for the slowest warp (base program +and shadow block), plus the O-1.14 laptop run (the Windows `igneum-pow` build on the box, the relay, `bench +--warps 50`). Known-failed shape: a drawn program whose verifier warp exceeds 10 ms cold (the acceptance rule bounds +the miner's side, not the verifier's; `dr736` already FAILs at 10.51 ms cold one-core, but it is not the shipping +class). Gate: the worst program under 10 ms cold on the half-core proxy and on the laptop. + +O-1.14 route (coordinator, 7 October 2026, 10:1x UK): no US laptop is due, so the laptop run is replaced by a +rented 2019-class CPU host through the fleet agent, capped at two hours of rent; the Linux `igneum-pow` from the box +(the same binary as the proxies) runs `bench --warps 50` for v2, mx8, mx8+sh256x27, dr368 and dr736 (the +known-fail) on it; INCOMPLETE with the numbers so far if the cap lands first. The Windows exe was also built on the +box for the day a laptop appears (1,009,675 bytes, sha256 fbed7538...e6c9). Outcome, 09:40 UK: no 2019-class CPU +host stood up. Vast accepted and dropped five CPU-class rents within 30 s each (i7-9700K, i5-8500, Xeon W-2133 and +W-2123) under the account's automatic new-account spend limit (support ticket open since 6 October), and RunPod has +no 2019-class CPU pod; so O-1.14 reads INCOMPLETE on the box proxies today and stays a precondition of the freeze. +Next try: the US laptop when it registers on the relay (the exe is ready), or Vast once the spend limit lifts; the +bench script is staged and runs in minutes. Correction, 10:4x UK (fleet agent): the provider dropped nothing; every +rent stood up and ran, hidden by Vast's instance listing cap of 25 rows on an account holding 38, so the hosts sat +idle and were destroyed. The fallback is re-rented under the same word (i7-9700K class, two-hour cap from its start, +read by id); the result replaces this line when it lands. + +O-1.14 RESULT, 7 October 2026, 09:49 UK, Vast instance 54613164, Intel Core i7-9700K (2019 desktop core, Coffee Lake, +read at 4,170 MHz during the run, 31 GB DDR4, Ubuntu 24.04), the box-built Linux `igneum-pow` (sha256 6d286783...), +`bench --seed igneum-genesis --day 2026-10-03 --warps 50` on one core (`taskset -c 1`), the host otherwise idle; log +`docs/analysis/attack-pass/o114-i7-9700K-2026-10-07.log`: + +| Class | Cold max (ms per warp) | Average of 50 (ms) | Gate 10 ms | Box one-core cold | Box half-core | +|---|---|---|---|---|---| +| v2 | 1.582 | 1.280 | pass | 1.30 | n/a | +| mx8 (class v3) | 5.394 | 5.267 | pass | 4.67 | 7.56 | +| mx8+sh256x27 (class v4, the target) | 6.334 | 6.006 | pass, 3.7 ms of headroom | 5.06 | 8.23 | +| dr368 | 5.540 | 5.426 | pass | 5.32 | 8.16 | +| dr736 (the known-fail) | 10.290 | 10.042 | FAIL, as it must | 10.51 | 15.49 | + +Cache fill 276 ms on the 9700K core (box 361 ms, M5 Max 175 to 181 ms). The 2019 desktop core sits between the box's +two proxies as the arithmetic predicted (1.2x the box one-core cold on v4, 0.77x the half-core); the known-fail +fires on it. A 2019 laptop core at 3.5 GHz reads about 15 to 20 percent slower than this desktop part (approximate, +clock ratio), so about 7.0 to 7.6 ms on v4, still under 10 ms. Consequences: a 2019-class node verifying class v4 +spends 0.6 percent of one core at 1 bps and 6 percent at 10 bps; a header flood needs about 160 invalid headers a +second to saturate one such core; a pool verifies about 160 shares a second per core; IBD of 108,000 headers is +about 11 minutes of one core. The implied ladder ceiling on this core: the shadow costs 0.74 ms per 55,296 +instructions (v4 minus mx8), so the 4.0 ms of headroom buys about 300,000 more shadow instructions, N about 650,000 +counted ops at the 1.83 convention (approximate), against 370,000 on the half-core proxy and 1,060,000 on the +2.5x rule; the half-core proxy stays the standing pessimistic rule and the ladder's ceiling should be taken from +it, not from this desktop part. O-1.14 is CLOSED on a real 2019-class core for the genesis program; the F6 row +still owes the 10^5-program worst case before it reads PASS. + +Result (average, verified on the box): class v4 `mx8+sh256x27` runs 4.90 to 5.06 ms per warp cold on one EPYC +9454P core (nice 19, taskset), 8.23 ms on the half-core proxy (both SMT siblings busy). Under 10 ms. Status +RUNNING: the 10^5-program worst-case search and the O-1.14 laptop relay run are owed before the row reads PASS. +What a failure moves: an acceptance-rule bound on verifier cost; the ladder's ceiling set from the measured core. + +### F7. Era-draw bias harness and census (node lane harness, hash lane census) + +Method: the fast-time 3-node network (`infra/fast-time/`) with an adversary withholding or publishing the last blue +block before C_era(n) to re-roll the draw; a census of 2^20 era seeds for stride, ROT and weight-perturbation +classes with gain over 1.1x; the 64-bit seeding of the day-key stream against the spec's intent. Known-failed shape: +a re-roll of the era draw inside the 2 s publish window, or an era class (stride bijection, all-equal ROT, low-weight +M) with a chip gain. Gate: no re-roll inside the publish window; no era class with gain over 1.1x at a fraction over +2^-20; the draw's input set as the spec states it. + +Result (full record `docs/analysis/attack-pass/f7-era.md`; harness `tools/attack/f7-era/`). Census: 2^20 and 2^24 era +seeds through `generator::era_draw` over `V3_ALLOWED` (the chain's path), classified; the planted known-fail/known-pass +of the classifier fired and the sound draw raised nothing. No era class with gain over 1.1x at any fraction (the richest +is M = 1 at 1.0034x, absent in 2^24; every class over 2^-20 is 1.0000x to 1.0007x); the stride is a bijection on every +sample (0 even M), R and pos and the M bits uniform; the op-weight corners (15 to 31 of 75) are 1.0x against the GPU, 0 +memory effect. The 64-bit day-key seeding is the spec's intent (spec 1.8.4); 2^16 days are all distinct, birthday 2^-33. +Harness: the 3-node fast-time network (`reroll.mjs`, ports 29800+, suffix 980) with an adversary holding the last block +before the cut; known-pass (`--vdf-ms 0`) fires at 1 of 6 cuts (seed = adversary block), known-fail (`--vdf-ms 5000`) +is silent at 0 of 6, both SOUND. The node has no era VDF yet (`seed_below` is a plain block hash, era-layout.md section +8), so the harness cannot show the real 2 s-window gate; the era draw's grinding resistance rests on the 1-hour VDF of +spec 4.4 (re-roll needs a 1,800x evaluator, spec 4.6 gives 300x; forge needs 20 days of 100% hash). Verdict: census PASS, +64-bit seeding PASS, harness INCOMPLETE with the written argument. Logs on igneum-build-1 +`/srv/builds/igneum-wt-attack/attack-f7/census-2p24.log`, `census-2p20.log`, `reroll-knownpass.log`, `reroll-knownfail.log`. +What a failure moves: the draw procedure or the C_era cut rule; a redraw rule for the era stream. + +Sub-row (a) CLOSED, 7 October 2026, 15:1x UK (the era-VDF lane, launched by the coordinator on this row's INCOMPLETE): +the era VDF is in the node (fork `era-vdf-node` 394a5902 on `release-0.3.20-node` c4459193, behind +`era_vdf_activation_daa`, never on any network until the founder sets it per network; repo master a4eaf766 carries the spec +text, the record `docs/analysis/era-vdf-2026-10-07.md` and the harness `tools/era-vdf/reroll.mjs`, which attacks the +era cut directly now that the node takes `pow_era_blocks` and `pow_era_lead` from the override file). Against the +REAL era cut (era 120 DAA, lead 20 on the fast-time file, three nodes on igneum-build-2) the harness fires with the +VDF off (6 of 6 cuts: the adversary's block is the cut block and its hash the seed, known the instant it is built) and +is silent with it on (0 of 6 across six cuts: the adversary's 5.4 to 6.6 s evaluation with the node's own code against +a 1 s block interval, the honest chain 3 to 10 blocks ahead when it published, three nodes agreeing on every era seed, +the record ready at every era start).

Meaning per tier: the shadow block of every drawn program stays within 5 percent of its naive count under the harness's rules and the honest compiler finds the same shortcuts, so no chip gets a shadow-side discount (a miner on a card pays the full block, a hypothetical ASIC gains nothing here) and the chain's verifier agrees with the harness on every program (0 mismatches), so no node disagrees with another on any drawn block.

F3 protected its own directory through the box mirror's `.git/info/exclude`; the lane +then added `attack-*/`, `target-attack-*/`, `tools/attack/` and `.build-remote.log` to that file at 10:1x UK, after +which `git clean -fdn` on the mirror lists nothing (the clean has no `-x`, so the exclude file applies). The class +check is owed to the build-server lane: the clean line should spare a lane's declared scratch prefix (`-e 'attack-*'` +style, or read a per-worktree exclude list), and a CI check should fail a remote-run.sh whose clean line lacks it. +OPEN until that check lands (CLAUDE.md: a rule row closes only with its check). + +AP-H2 (this lane's own, 7 October 2026, 13:3x and 14:5x UK, twice). Two census runs launched from the same crate's +`target/release` binary path on the box mirror: a rebuild of the crate at a new commit replaces the binary under a +run still in progress, and every chunk the run launches after that executes the new commit's code with the old run's +label (the 07a809a7 control's later chunks ran 8bdcbdd8; the ddacfbd3 class check's later chunks ran 017e7037). Both +runs were caught by their attempt histograms (attempts 32 and 35 under a cap of 32) and their contaminated chunks +discarded. Fix in the lane's launcher: `run-census-chain.sh` copies the binary into the run's own scratch directory +before the first chunk and runs from the copy, so a rebuild cannot reach a run in progress; a run's record names the +sha256 of the copy. Class check owed: the same rule for every lane's long run (the box's build runner could refuse to +replace a binary that a running process has open, or stamp the commit into the run's log at every chunk). + +## Ledger rows + +AP-F1-1 (hash lane; ruling asked). At 10^5 class v4 programs one program (`attack-f1/37341`) compresses by 5.078 +percent (13 of 256 shadow instructions per pass), 0.078 points over the gate's first clause, on 1 of 100,000; every +other program is within 5 percent and none over 10. The saving is the same local shape as on every program (a +register written twice from one source with no write between), nothing crosses a pass, and clang -O3 removes the +same instructions from the honest kernel (IR counts match the harness on the worst programs), so a chip gains nothing +relative to a card: no shortcut. The gate as written counts honest-compiler simplification as compressibility. Two +ways to close: re-word gate (1) and row F1 to "compressible beyond the honest compiler's own simplification" (the +question is chip-relative compression), or a shadow-draw redundancy bound in the next +class (reject a shadow with over 12 peephole-removable instructions per pass, rejection about 1e-5; class v4 is on +the live vote). Ruling (coordinator, 7 October 2026, 12:3x UK): both. Gate (1) and row F1 re-worded to "no +compression of the shadow block beyond the honest compiler's simplification, measured against that compiler on the +same program" (sent to the cryptanalysis lane for the plan and the public report), under which the 5.078 percent +letter miss at honest-compiler parity is a PASS; and a shadow redundancy bound on the v5 generator's list beside +AP-F4-1 and AP-F8-1 (the generator refuses a shadow block whose honest-compiler simplification exceeds a stated +fraction; the v5 lane sets the fraction from F1's census), gated by F1's harness on 64 seeds of the v5 stream. +The fraction is 3.0 percent (v5 lane, class-v5 45e29cb0; 384 of 100,000 draws redrawn in its census, 3.8e-3, against +F1's histogram where the 3.0 to 5.5 percent bins hold 397 of 100,000); the plan's 1.1 sentence carries the number. +Status: F1 PASS; AP-F1-1 FIXED-AND-PASSED against v5 once the bound is in the v5 generator and F1's census passes. + + +AP-F5-1 (algorithm and hash lane, ours; the ladder lane is closed). The k about 0.33 chip-efficiency figure is +framed as a measured calibration ("the X9's core", `fud-ledger.md` M32 L172; "measured class", `ladder` branch +`docs/design/latency-ladder.md` section 5a). The Antminer X9 was withdrawn before launch and never benchmarked, so +k about 0.33 is a claimed datasheet bound, not a measurement. This also puts the merged ledger X34 ("RandomX has a +shipping chip") in question. Fix owed, held until the coordinator's research agent confirms the withdrawal and the +no-benchmark fact: relabel k about 0.33 as a claimed pessimistic bound from a withdrawn design in `evidence.md` row +17, `fud-ledger.md` M32 and the `ladder` branch; reverse X34 if the withdrawal is confirmed; keep 2.1x at k = 1 on +the GDDR7 measured anchor as the headline with the k range beside it. Re-gate after the re-cut. Status: FIXED on the docs rows (evidence 17, M32, ladder 5a on branch attack-ladder-5a d3cb17b6; attack-pass +rebased on master a3678789 after X36); FIXED-AND-PASSED once the site lane's X34/X36 served rows are confirmed in +one voice (no objection received) and the sweep is re-run against the re-cut sentence (the numbers are unchanged, so +the re-gate is the identity check and one `model.py --section chip` run against the new wording). Re-gate done 7 October 2026, 09:5x UK: the 5090 +bench row still reads 5.7x / 4.1x / 3.2x / 2.1x / 1.5x (v3; v4 at k = 0.3 / 0.5 / 1 / 1.5), identity grep 0 hits +over 290 export files, the site lane confirmed the served text agrees. AP-F5-1: FIXED-AND-PASSED. + +AP-F8-1 (hash lane; the generator fix is the Counter ASIC lane's on the v4 seam, routed 7 October 2026, 10:3x UK). +The class v4 item read map is not uniform. F8 phase D, one program, 2^26 nonces: the top 0.1 percent of items take +0.520 percent of reads against 0.115 percent for the uniform control (4.05x); the top 1 percent take 2.49 percent +(1.37x); one item (0xca5b92) takes 78,479 reads, 153x the mean; read site 15 feeds 6.37 percent of its reads into +that 0.1 percent in all 8 iterations; the excess grows with N as a real skew does. Sized: a chip caching the hot +0.1 percent in SRAM serves about 0.5 percent of reads from cache, so the shortcut is under one percent of rate today; +an auditor flags a non-uniform read map in a design that claims uniform random reads, and site 15's index derivation +is the cause to name. Fix asked: per-site index whitening or a rejected class above a bound. Re-gate: the top +0.1 percent within 1.2x of the control over 2^26 nonces on every one of 64 seeds, with F8's harness against the +Counter ASIC lane's branch. Phase E (the 64-program census) decides whether it is one program or the class. +Framing from the Counter ASIC lane (the generator's owner, 7 October 2026, 10:5x UK): class v4's item map is not +designed to be uniform per program. Layer 8 (spec 01 section 1.13.1) gives each load site k_off = below(3), so a +site reads the whole dataset, a half or a quarter under the era's stride and interleave; a quarter-window site +concentrates 4x on its quarter by design, which is the 4.05x at the top 0.1 percent, and the windows exist so a +chip's SRAM mirror must hold the whole dataset every hour (the Counter ASIC 2.0 windows-union census). The right +control is therefore the window model from the program's own 16 draws, reported beside the uniform control (what an +auditor sees first); the number that must be explained is the single item 0xca5b92 at 153x the mean (window +coincidence under the era mapping with a stated tail, or a low-entropy index source at site 15, which would be a +fault). The lane reproduces with F8's harness on branch `ca3-v4-uniform`, waits for phase E, re-prices the chip +consequence (a 0.1 percent hot-set cache, about 1.7 MB of SRAM, serving 0.5 percent of reads: under one percent of +rate) and changes the generator only on a fault beyond the model, since v4 is on the live devnet's vote. F8 was +re-briefed to carry both controls and the per-site table. Raised to the coordinator: plan 1.4 gate (4) and row F8 +say "within 6 sigma of uniform"; if the design is windowed, the gate text must say "uniform within the window model +of spec 1.13.1" before the freeze tag, or every reviewer files the windows as a finding on day one. +Coordinator's ruling (7 October 2026, 11:0x UK), accepted: the right null is the window model derived from the +program's own draws; F8 is re-gated against it, and the finding stays open only for the excess beyond the window +model (the 153x item, or a low-entropy source at site 15 if the 64-seed census shows one). No generator change to +class v4 is allowed: it is on the live devnet's vote, and a class change before the flip splits the chain. If the +census shows a real fault it goes to the coordinator priced; otherwise the record carries the documented null and +the hot-set bound (a 0.1 percent cache, about 1.7 MB of SRAM, under one percent of rate) goes into the next class. +Gate wording settled (coordinator, 11:2x UK): plan 1.4 gate (4) and row F8 now read "uniform within the window +model of spec 1.13.1, layer 8; the excess beyond it within 6 sigma over 64 seeds", carried into the plan's scope +text by the cryptanalysis lane so the public report states the windows. +Mechanism (hash lane, branch `ca3-v4-uniform` 095f84a7, `docs/analysis/ca3-v4-uniform.md`, harness +`tools/ca3-v4-uniform`, 7 October 2026, 12:3x UK): the windows-union null (a Poisson mixture at 416 / 288 / 736 / 608 +reads per item by quarter from the program's 16 draws) moves the top 0.1 percent from 0.115 to 0.160 percent, 1.39x, +not 4.05x; every per-site row of F8's attribution except site 15 is the window model. The rest is the LOAD SOURCE: +site 15 is the load at 63 reading r6, whose last writer is `or` at 61 (r6 = r6 | r4), so the source is all-ones with +probability about (3/4)^32 per read; under the era map x = 0xffffffff is item 0xca5b92, the hottest item exactly, and +the next seven hottest are the seven one-zero-bit sources whose zero survives the window mask (7 of 7); the measured +count fixes the bias at p = 0.7585 per bit. The class: a load whose source's last writer is lossy (or: 0.30 percent +of a site's reads on 0.1 percent of values; mul, trailing zeros: 1.07; mulhi: 0.79; an or of an or: about 4.5). +Static census of 1,024 chain-shaped v4 programs: 96.6 percent carry a lossy-sourced load (48.5 percent or, 4.9 +percent an or chain, 73 percent mul, 64 percent mulhi); predicted S_0.1 median 0.45, 90th 0.88, 99th 5.3, max 9.8 +percent; p1 / p2 / p3 predicted 0.58 / 0.32 / 4.72 against measured 0.52 / 0.27 / 4.60. The fault sits in the +acceptance rule's blind spot: part (a) takes any write as fresh, part (c) counts saturation on final values only. +Consequence: the 1.2x-against-window gate fails 96.6 percent of today's programs, so it is withdrawn as a v4 gate and +becomes the v5 generator item's gate (draw a load's source from registers whose last writer injects; a dynamic check +counting saturated load sources), with F8's phase E as its test. Chip side: the top 0.1 percent of items is 1.07 MB +of SRAM (0.53 mm^2, about USD 0.25) serving 0.52 percent of p1's reads and 4.6 percent of p3's, at most 1.005x and +1.048x in rate; the ceiling under rule (c)'s 120-of-128 floor is one site repeating its item in all 8 iterations, +6.25 percent of reads, 1.067x. That 1.067x is the v4 hot-set bound the record carries. No generator change to v4; +the hash lane takes the two flip options priced to main. +Ruling (the founder, 7 October 2026, 15:2x UK): option A, the class v4 amendment ships in 0.3.20, the feature node (0.3.19 is the app-only cut on the unchanged 0.3.17 node pin; corrected by the coordinator) (a load's source drawn +only from registers whose last writer injects or is a rotate, the v5 rule applied now; a new program stream and +seven re-exported packs on branch `ca3-v4-amend`, the hash lane), with limited testing. This lane's part is the proof +of the fix: F8's hot-set census at 2^24 nonces on each of 64 seeds of the amended stream, on the box's CPU path as +phase D ran, gate: the top 0.1 percent of items within 1.2x of the window model derived from each program's own 16 +window draws, one number per seed; reported to the hash lane, main and the Counter ASIC lane. The amended stream has +no lossy-sourced load by construction, so a seed over 1.2x there is a finding against the model's own tail, not the +fault, and the record says which. +Second harness (F9 sub-row b, 10^6 seeds, 12:5x UK): the same class from the other side, the per-site address trace: +11,696 of 1,000,000 passing programs concentrate 1 percent or more of their reads on a hot set (worst 17.3 percent, +seed 842871, an `or`-written load source all-ones in 36 percent of evaluations), so F9-1 merges into AP-F8-1 and +F9's harness is the second re-gate of the amendment, run on the amended stream beside F8's 64-seed census. +Re-gate interim (7 October 2026, 13:2x to 13:5x UK, box 2): F8's 64-seed census at 2^24 nonces against the amended +stream (igneum-pow 8c728ca3, sub-version 1; pairing verified, the harness draws the devnet epoch-0 program as +1a4230699a6b9c60) at 30 of 64 seeds shows nine over 1.2x of the window model (p31 29.27x, p11 5.45x, p19 3.32x, p6 +3.11x, p23 2.04x, p4 1.57x, p10 1.50x, p26 1.30x, p25 1.28x), p6's hottest item predicted from "site 13, r0, +all-ones, last writer a load at 12": a load-after-load chain (a hot address yields a fixed dataset word, which is the +next load's address), which the source rule admits because a load injects. Rule-level reading, checkable in code: +generator.rs line 1326 sets `entropy_kept[dst]` true for a rotate whatever it rotated, so an or-saturated register +rotated once is an admitted source and the rotate preserves the saturation. RETRACTION: F9's hot-set census run on +box 2 against the 8c728ca3 build (10^6 seeds, 1,871 flagged, worst 9.66 percent) was not a re-gate: the F9 harness +draws through `candidate_class` with its own era class, not through `chain_program` where the rule lives, and the +amended and the old binary print the identical program for seed igneum-f9/518927; those numbers describe the old +stream under a changed evaluation and are withdrawn; the harness is being given a `chain_program` draw mode so it can +serve as the second re-gate. The hash lane confirmed the reading (14:0x UK): the amendment's rule is keyed on the +era-composed class, so a draw with no era (F9's path) is the old stream, and on the chain path the residual is real: +p6's load at 12 had a saturated source itself, read one constant word and left a constant in r0, which the rule +counts as injecting; a rotate keeps 0xffffffff, so or-then-rotate-then-load passes too. Both are saturation delivered +through a writer that preserves it. Fix shape put to the owner of sub-version 2 (the Counter ASIC lane): dataflow +freshness instead of a one-writer look-back (fresh at the start; a load keeps dst fresh only if its source was fresh; +add, sub, xor, mad, shfl fresh if either operand was; rotl, rotr only if the operand was; or, mul, mulhi never; a +load's source drawn only from fresh registers), with the dynamic (c') check on load sources as the backstop; a stream +change, so sub-version 2 with new packs, ids and fingerprints. +RE-GATE VERDICT on sub-version 1 (7 October 2026, census ended 12:55:55 UTC, 13:55 UK; box 2; igneum-pow 8c728ca3 +paired with release-0.3.20-node 8097d600, pairing id 1a4230699a6b9c60 verified; 64 seeds p2 to p65 at 2^24 nonces, +chain path, window-model control; log `/srv/builds/igneum-wt-attack-regate/attack-f8-regate/log/`): FAIL the pass +line. 53 of 64 seeds under 1.2x of the window model (0.9915x to 1.16x, no predicted source); 11 over: + +| Seed | Over the window model | Over flat | Hottest item, reads of 2^31 | Predicted source | +|---|---|---|---|---| +| p31 | 29.27x | 31.99x | 0x74e2b8, 5,365,527 | site 4, r4, all-ones, last writer rotl at 3 | +| p11 | 5.45x | 6.00x | 0x0eec66, 31,486 | site 1, r7, all-ones, last writer or at 63 (the previous iteration) | +| p45 | 4.55x | 6.37x | 0x400000, 5,644 | site 1, r4, zero, last writer mulhi at 59 | +| p19 | 3.32x | 3.93x | 0x400000, 28,114 | site 37, r5, zero, last writer load at 32 | +| p6 | 3.11x | | 0x3bf40d, 13,792 | site 13, r0, all-ones, last writer load at 12 | +| p23 | 2.04x | 2.85x | 0x09dd36, 13,848 | site 16, r7, all-ones, last writer load at 14 | +| p4 | 1.57x | 2.11x | 353 reads | none (window tail) | +| p34 | 1.51x | 1.87x | 0x400000, 1,547 | site 23, r6, zero, last writer rotr at 12 | +| p10 | 1.50x | 1.65x | 353 reads | none (window tail) | +| p26 | 1.30x | 1.54x | 0x000000, 7,637 | site 10, r1, zero, last writer rotl at 2 | +| p25 | 1.28x | 1.65x | 363 reads | none (window tail) | + +Three residual classes, each a constant (all-ones or zero) delivered to a load through a writer the rule admits: +(1) saturation or zero preserved through rotl, rotr, load or mad; (2) zero made by mulhi; (3) the iteration +boundary, where the rule's writer state starts fresh at instruction 0 so an or at 63 feeds a load at 1. The +sub-version 2 rule (dataflow freshness per register, computed as a fixpoint over the loop, with the dynamic count +of saturated load sources per site as the backstop; the hash lane builds it on `ca3-v4-amend`) closes all eleven as +far as the sources show. Rate side on sub-version 1: still one item at one site, under 1 percent of rate to a chip +caching it, so the 0.3.20 ship is safe on rate; the auditor's flag is what sub-version 2 removes. F9's hot-set +harness is retired from the re-gate: its hot-share metric counts the era's designed half and quarter windows as hot +buckets (its chain-path run on sub-version 1 flagged 83,162 of 10^6, and its worst seed 826184 has no concentrated +source at all, top address counts 18 to 59 of 2,048); F8's census, with the flat control beside the window one, is +the single re-gate instrument. +Sub-version 2 (07a809a7, the stream identical at 8bdcbdd8 for every seed accepting within 32), the same 64 seeds at +2^24, 13:10 to 14:2x UTC: at 39 of 64 seeds, 8 over 1.2x of the window model, worst p23 4.82x. Three are the window +model's tail (p4 1.22x, p8 1.38x, p10 1.50x, no predicted source); five are constants the freshness rule cannot see +because it tracks lineage, not value: p23 (0x000000, 41,727 reads, zero from xor of a register with itself at +instruction 0), p34 1.25x (sub of a register with itself), p15 2.57x (zero through rotl at 0), p18 2.50x and p19 +3.32x (a load whose address is constant delivers one word to the next load; p19 is byte for byte the sub-version 1 +program). (c') cannot catch them: 164 of 16,384 per site is about fifty times coarser than the gate (p23's item is +0.002 percent of all reads and still 4.8x at the top 0.1 percent). Fix shape sent to the hash lane: forbid +self-operands for xor, sub and mad in the draw; a dynamic per-site bound on the most repeated source value (any +value) set from the gate; a load's dst fresh only if its source passes it. Rate side unchanged (one item at one +site, nothing to a chip); the auditor's uniformity test is what fails. +Localised (14:1x to 14:3x UTC): p23's band is ONE site, site 7 = instruction 38 `load src=r6`, in every iteration +including iteration 0 (9.5 percent of that position's reads on the top 0.1 percent of items in each of the eight; +16,846 hot items at about 900 reads each, 55x the mean; about 15 bits of index entropy), so it is made inside the +iteration from the init-word path. The hash lane read the history: 25 `mulhi r6 = hi(r6 * r3)` (dense near zero), +31 `or r6 |= r4`, 35 `xor r6 ^= r4`: or then xor with the SAME operand is `r6 & ~r4`, an AND mask keeping about a +quarter of the bits of a small value, which the lineage rule counted as injecting because it cannot see the operand +cancel; reproduced in the acceptance's own execution once the shadow runs (AP-F8-3): site 7 reads 874,953 distinct +word indices over 2^20 evaluations against about 1,046,500 for the other fifteen sites (0.84 of uniform, 2.2 s) and +0.55 at 2^24 (35 s). Neither dataset- nor nonce-dependent: a rule reaches it. Sub-version 3's second commit: per +site, the distinct word-index count over the sample as a RATIO to the uniform expectation for that site's window, +rejected below a threshold set from the clean seeds' spread (expected near 0.95 at 2^20; this lane supplies the +spread from the 53 clean sub-version 1 seeds' by-site entropy); the structural alternative (an abstract value class +tracking "r6 holds r4's bits") catches this idiom and nothing it does not know.

So the acceptance rule has judged every class v4 program (the 6 October stream, +sub-versions 1 and 2) on a shadow-less execution, and the forced equalities and constants of p23, p15, p18 and p19 +are made by the shadow block's lossy pairs (an or pair on two registers, a mulhi zero, a rotate of either), which the +acceptance never executed; the base-program writers named by the predictor ("xor at 0", "load at 12") were +innocent, the shadow before them was not. Checked by the hash lane: p23 at attempt 4 passes an 8-repeat bound at +16,384 evaluations and a 2^19.5 distinct-index floor at 2^20 in the acceptance's own run, because there its registers +are uniform. Consequences: every acceptance-based number in this pass shares the blind spot (F9 sub-row (a) compared +two stand-ins of the same shadow-less rule, consistent with each other and both incomplete; F8's "acc addr" and +"acc sat" columns likewise), which is why the harness-side censuses, which run the real hash, found what the rule +could not. Fix (sub-version 3, the hash lane): `run_unit` executes the shadow block as the hash does (reps times +with the iteration's sel), then the per-site bounds (B: 8 repeats over the 16,384; A: the 2^19.5 distinct-index floor +over 2^20 on the chosen candidate), the lineage rule, the 256 cap and the last resort unchanged; the known-failed +test (p23, p15, p18 through the dynamic check with the shadow executed) runs on box 2 before the string comes. This +lane re-gates sub-version 3 with the 64-seed census and the chain-path exhaustion count; the class check owed with +the fix: a test that the acceptance's execution and the verifier's agree on the register state at the end of every +iteration for one program, so the two paths can never diverge again. +Status: FINDING-OPEN; closes with sub-version 3's re-gate. + +Any further finding is logged here and in `docs/fud-ledger.md` with its owning lane (hash and algorithm: fixed in +`igneum-pow` behind a test and re-gated; node: the node lane, relay agent) before the row is marked FIXED-AND-PASSED. diff --git a/docs/analysis/attack-pass/f1-shadow.md b/docs/analysis/attack-pass/f1-shadow.md new file mode 100644 index 000000000..a2fd37ea9 --- /dev/null +++ b/docs/analysis/attack-pass/f1-shadow.md @@ -0,0 +1,344 @@ +# Attack pass F1: shadow block compressibility and shortcut search + +Row F1 of `docs/plans/cryptanalysis.md` section 4.2, fed into `docs/analysis/attack-pass-2026-10.md`. +Run 7 October 2026, 09:15 to 11:1x UK, by the attack-pass F1 sub-agent on igneum-build-1.

(1) The row's own failed shape is written in instructions. (2) Unit B's +extra 0.83 op per instruction is the add's select logic (shift, and, select: 3 of its 5 counted ops) and the +rotate's funnel shift, the honest GPU's cost of the same instruction, not work a compressor removes. (3) The chip +model's `k` floor is derived per instruction (`algorithm.md` 5.3: 0.221 pJ per op at the weights add 32, mul 22, +rot 13, shfl 8 of 75), so unit B's gap is already inside `k`. Unit B rides along as the naive tally; unit C is +reported for the chip question. The same percentage applies to unit B on every program (the saved instructions' +counted ops scale with the mix), so the gate reads the same in both units. + +Unit note for the algorithm lane (AP-F1-1, below): the `k = 0.3` floor divides a per-instruction energy by a +per-counted-op energy. + +## 3. Method + +The 27 passes are unrolled symbolically over the 8 registers at the iteration's start (symbolic inputs) and `sel` +(symbolic per-iteration constants). Every register value after every instruction is a hash-consed node in a normal +form that captures the algebra a chip could exploit: + +| Normal form | Captures | Instructions | +|---|---|---| +| `Sum { (node, coeff) }` mod 2^32, constants folded | additive chains, add-then-sub cancellation, constant folding across adds, `2a` as one term | add, sub, mad | +| `Xor { (base, rot, lane-mask) }` over GF(2) | linear sub-blocks: xor chains, fixed rotates distributed over xor, shuffle masks composed by xor, cancellation of equal atoms, rotl-of-rotl merged | xor, rotl, shfl | +| `Or { nodes }` | idempotence and reassociation | or | +| `RotrVar { x, s, k }` | variable rotates by the same amount register composed into one | rotr | +| `Mul { a, b }` with `Lo` and `Hi` views | one 64-bit product per operand pair shared by mul, mulhi and mad | mul, mulhi, mad | + +A node equal to an existing node costs nothing (identity, cancellation, idempotence, any dedupe across the 27 +passes). Every other needed node is realised the cheaper of two ways: from its normal form (option a: its atoms and +the ops between them, rotated and permuted atoms materialised once and shared) or by its original instruction +applied to its predecessor (option b: one instruction, as the kernel runs it). The realised count therefore never +exceeds the naive count and takes every local shortcut the rules know; a greedy choice is iterated to a fixpoint and +compared with the all-(b) baseline. Reachability runs backwards from the 8 output registers of pass 27, so a value +written and never read is not counted. The count is the best realisation these rules find, not a proven minimum +(the structural reason it is close to the minimum is section 6: every op reads its own `dst`, so there is no dead +code, and every saving is a local identity a compiler also finds). + +Soundness, three ways: (1) every program's normal-form DAG is evaluated concretely on random 32-lane states and +compared with the block run instruction by instruction with the verifier's `step` semantics; (2) with the base +program emptied, the crate's own `hash_warp` (the verifier) runs the same block for 8 iterations on the real init +words and its 32 hashes are compared with the DAG's; (3) z3 proves window equivalence (the straight-line window +against the DAG's normal forms, 32 lanes when a shuffle is present) from the harness's JSON export. + +Known-failed shape: a shadow that constant-folds or dedupes across its 27 identical passes so a chip pays fewer than +55,296 shadow instructions per hash. + +## 4.

The firings were rerun on the fixed binary. + +## 5. Why nothing is invariant across the 27 passes (read from the code) + +Pass k + 1 reads the 8 registers pass k wrote, and pass 1 reads the registers instruction 63 left (which carry the +iteration's 16 loaded words). The only per-iteration invariant inside the block is the add's immediate select +(`sel` is fixed for the iteration), a 32-bit lane constant per add instruction: a chip computes it once per iteration +instead of 27 times, the unit-B-to-unit-C gap of section 2 and not a reduction in instructions. Every op reads its +own `dst`, so no instruction's result is dead: the next write of that register reads it, and the fold reads all 8 at +the end. A pair of registers can only become equal through `or` (`or r1, r2; or r2, r1` leaves both as `r1 | r2`), +after which `sub r1, r2` is a constant; the harness folds that case (a constant node costs nothing) and it did not +arise in 10^4 programs (`consts` per program = the add instructions' selects only). Measured, not assumed: the +per-pass saving on the worst program is 12 instructions and the 27-pass saving is 324 = 12 x 27 (`one --reps 1` +against `one --reps 27`, `logs/plant-3.log` and section 7), so no dedupe crosses a pass boundary. + +## 6.

Reservations, stated: (1) the worst of 10^4 sits at 4.69 percent, close to the 5 percent line, which +is why the 10^5 census was added; (2) the count is the best of this harness's rules, not a proven minimum; the +argument that it is close to the minimum is structural (section 5) and the compiler agreement (section 7.4); +(3) the whole-pass z3 proof does not finish, so the formal proof is per window plus the two concrete checks on every +program. + +Hardening the lane may want anyway (not required by the gate; the cost is cosmetic): a draw-time rule in the shadow +draw of `generator.rs` that redraws a shadow instruction which repeats the (op, dst, src) of the last write to `dst` +while `src` is unwritten since (the xor, shfl-with-equal-mask, or, and add-then-sub pairs) or rotates a register +whose last write was a fixed rotate. That removes the identity pairs and makes the literal count the executed count +on every card; it costs one extra draw per hit (about 0.6 percent of shadow slots). Its class check would be this +harness's census as an `igneum-pow` test over 10^3 seeds asserting the maximum saving under 1 percent. Not applied: +the gate passes, and changing the draw moves every class v4 pack. + +## 10. Ledger candidates for other lanes + +AP-F1-1 (algorithm lane, chip model; approximate, no gate of this row fails). The attacker's `k = 0.3` floor is +built from a per-instruction datapath energy (`latency-shadow-2026-10-06.md` section 6: 0.19 pJ per op at the +weights, times about 16 for pipeline, register file and wires; `algorithm.md` 5.3: 0.221 pJ per op, floor 0.32) +divided by the 5090's 11 pJ, which is per counted op (1.83 per instruction; section 5 of the same file, the rung N +in counted ops). In one unit the same inputs give a floor of about 0.15 (3.0 pJ per instruction over 20 pJ per +instruction on the 5090, or 1.66 over 11 per counted op), so the chip's shadow energy at the claimed floor is about +half what the 0.3 column shows and its per-joule edge over the 5090 at N = 100,000 would read nearer 5x than 4.1x +at that floor. The `k = 1` and `k = 0.5` columns are unaffected (they are defined on the 5090's own unit). Owner: +the algorithm lane (F5's model sweep); what it moves: the `k = 0.3` column's label and value in `latency-shadow` +section 6, `algorithm.md` 5.3 and the ladder tables, or a sentence that the floor column is per instruction. + +Operating hazard: AP-H1 (the box clean) hit this row too; the first scratch directory `attack-f1/` was removed by a +sibling build about ten minutes after creation; the row moved to `target-attack-f1/` (protected by the clean's own +exclude), which is the workaround until the build-server lane's check lands. + +## 11.

A schedule names per DAA range the direction and how many residues carry no signal: 11 residues give 8,900 bps in every window whatever the window's alignment, 10 give 9,000. "None" blocks alternate between no bits and both bits, so the chain shows both forms read as none.

The FPGA lane is already behind every GPU tier on reads per watt (F5: 10 to 20 M reads/s/W against the gate's 27 M), so no home miner (8, 12, 16, 24 or 32 GB), rig or pool on any vendor or OS sees a competitor appear, and no day's difficulty moves by a measurable amount | +| M2 (DSP-bound FPGA) | 0 in 2^28 | PASS | nothing moves for any tier | +| Chip (programmable constants, the chip-model-v3 recompute chip) | 0 by construction | PASS | nothing moves; a taped-out chip cannot specialise per day | +| GPU and the CPU verifier | 0 by construction | PASS | every tier pays the same ops on every day | + +What the worst day buys, priced for the per-day LUT datapath (the M1 attacker) on the worst calendar day, 29,337: + +| Item | Value | Source | +|---|---|---| +| Fewer adders per mixer application that day | 231 to 206, 10.8 percent fewer | section 6.7 | +| Item derivations per unit of fabric that day | 1.121x (M1 gain) | section 6.7 | +| Hash rate of a recompute FPGA (items derived per hash, the `chip-model-v3` ops-per-hash attacker) that day | up to 12.1 percent above its ordinary day, an upper bound: the 128 dependent cache reads per hash and the shadow block are untouched by the draw, so the whole-hash gain is below the mixer's | `chip-model-v3.md` section 1 (ops per hash = 128 x 72 x 130); section 3 | +| Hash rate of the stored-dataset (f = 1) FPGA or chip that day | 0 (it derives no items per hash; the mixer is paid once in the daily build) | `funding.md` B2 rank 2 | +| Days a century at or over 1.1x | 12 (6 over, 6 at exactly 1.100x) | section 6.5 | +| Share of a century's hashes the M1 attacker gains | 12 / 36,525 x about 0.11 = 3.6e-5, 0.004 percent | arithmetic on the rows above | +| What one bitstream a day costs | one place-and-route of a large part: 42 to 160 minutes on a mid-size part (PRflow, FPT 2019, cited in spec 01 section 1.13), hours on a large one; on a rented 96-thread box (Hetzner AX162 class, about USD 0.35 per hour, approximate) under USD 3 per bitstream (approximate), and it compiles any time ahead because the calendar is public | spec 01 section 1.13; price approximate | + +So the bitstream is cheap and the gain is 0.004 percent of a century for the slower of the two FPGA designs: nothing +a home miner on any card, a rig or a pool on any vendor or OS can see, and nothing that moves a day's difficulty. + +What is being done about the M1 line: class v4 is not changed (it is the object on the live devnet's vote). The +rejection-and-redraw rule of section 8 is proposed to main for the next class, unless main reads the census as a +fault beyond the metric (this row does not: every class sits at its expectation and the worst day is an ordinary +draw). The rule costs one redraw on 5.6e-4 of days, changes no existing vector (day 20,729 has NAF sum 178; the first +day the rule would redraw is 22,633, about 5.2 years after genesis, section 6.5), and makes the M1 gate pass by +construction. `igneum-pow` is untouched by this row. + +## 8. Proposed fix for the next class: a rejection-and-redraw rule on the MUL draw (for main's decision) + +Shape, like the program acceptance rule 1.4.6 and `DeriveProgram::check`: draw the 16 `MUL`, test, and on rejection +continue the same stream with 16 fresh draws (so every later draw keeps its position only within an accepted block; +`RC` is drawn after the accepted `MUL` block). Tests, in order: + +| Rule | Threshold | Rejection probability per candidate | What it closes | +|---|---|---|---| +| Sum of NAF weights of the 16 `MUL` at least 163 (M1 cost at least 211, gain at most 1.095x against the median 231) | `sum_i NAF(MUL_i) >= 163` | 5.64e-4 (`expect-231.log` cumulative at cost 210) | the M1 tail: no day over 1.1x by construction | +| Every `MUL` of NAF weight at least 4 | `NAF(MUL_i) >= 4` | 1.30e-5 per day | `MUL = 1`, `2^32 - 1`, `2^a +- 1`, `2^a +- 2^b +- 1`: the M2 words (hygiene; M2 already passes) | +| `ROT`: at least 4 distinct amounts (the `DISTINCT_ROTS_FLOOR` idea of `derive.rs`) | `distinct >= 4` | 3.07e-5 per day | the degenerate rotation draws (hygiene; 0 ops moved, diffusion fine at 2 applications) | + +Total rejection about 6.1e-4 per day: one redraw every 4.5 years of chain time; `MAX_ATTEMPTS`-style exhaustion is +impossible in practice (64 rejections in a row at 6e-4 each). Class check to land with it: a unit test in `memhard.rs` +that plants a low-sum draw (stream seed chosen so the first MUL block fails) and asserts the redraw, plus this +harness re-run over 2^24 showing 0 days over 1.1x under M1 after the rule. The reproduction line for the finding +without the rule: `attack-f4 day --index 4819563 --median 231` (cost 197, 1.173x) and +`attack-f4 day --index 27952752 --median 231` (cost 194, 1.191x). + +Consensus consequence: the rule changes the day-key-to-constants map on rejected days only, so it must land before the +freeze tag. In the chain's first 100 years the sum rule redraws 12 days (6 under 1.1x and 6 at exactly 1.100x, +section 6.5), the first of them 22,633, about 5.2 years after genesis; no pack cut for the devnet, the testnet or the +first five years of mainnet changes. The per-word rule redraws no day in the first 100 years (no word of NAF weight +under 4 in `census-100y.md`); the `ROT` rule redraws one, day 57,146 (2 distinct amounts, 99.7 years in). + +## 9. What this row did not do + +* It did not time the verifier per day beyond the confirmation row of 6.6: the verifier's code path is + value-independent (no branch on a drawn value), so op counts are the exact metric. +* It did not search optimal single-constant multiplication costs (not computable at 2^28 scale); NAF is the standard + canonical bound and the ratio between days is what the gate asks. +* It did not census the era draw (F7) or the spec's intent for the 64-bit seeding (F7); the fact is stated in section 1. + +## 9. Reconciliation with adv-mixer-2's independent census (7 October 2026, 21:5x UK; main's order through the +crypto-engage coordinator: the two tables side by side, the median each used, one agreed figure) + +Both censuses read the same class, the FPGA LUT multiplier-adder area (no chip or GPU gain), with the same cost form, +64 + the sum over the sixteen MUL of (signed-digit weight - 1). They differ in one convention. This harness's +`naf_weight` (src/main.rs line 72) computes the canonical NAF of the constant as a `u64` and counts every digit, +including the carry digit at position 32 that a 32-bit odd constant carries with probability 1/3; adv-mixer-2's +`w32` counts the digits at positions 0 to 31 only, because a multiplier modulo 2^32 is never built with a digit at +position 32. Checked on 2^18 random odd constants: mean weight 11.442 with the carry digit against 11.109 without +(P(digit at 32) = 0.3334), cost 231.1 against 225.7. So this record charged every day about 5 adders a 32-bit +multiplier never pays, unevenly per day, which is the whole of 231 against 226 and of 12 against 15 days a century. + +| Quantity | This record (M1, carry digit counted) | adv-mixer-2 (model A, w32 modulo 2^32) | Agreed | +|---|---|---|---| +| Cost form | 64 + sum(NAF(MUL_i) - 1), NAF over u64 | 64 + sum(w32(MUL_i) - 1), digits 0 to 31 | adv-mixer-2's: the digit at position 32 costs nothing in a 32-bit multiply | +| Median per application | 231 (census over 2^24 chain days; mean 231.113) | 226 (exact, 16-fold convolution over all 2^31 odd constants; the log's provisional 231 superseded) | 226 | +| Threshold for a 1.1x gain | cost under 210 (NAF sum under 163) | cost A at most 205 | cost A at most 205 | +| Fraction of days over 1.1x | 3.264e-4 (5,476 of 2^24); exact expectation 3.243e-4 | 5.677e-4 (2^24 census); exact 5.694e-4 | 5.69e-4, about 2^-10.8, against the 2^-20 gate | +| Days over 1.1x per century (36,525 public days) | 12 | 15, listed in its Q4 | 15 | +| Worst public day | 29,337 (2050-04-28), cost 206, 1.121x | 29,337 (2050-04-28), cost A 203, 1.113x | 29,337, 1.113x | +| Genesis day 20,729 | cost 226, 0.978x | cost A 219, 1.032x | 219 | +| DSP-bound metric | M2: 0 days with k >= 2 in 2^28; k >= 1 at 1.067x | model C: P(k >= 1) 3.12e-5 (1.067x), P(k >= 2) 4.57e-10 (1.143x) | agree: under the gate at every k | +| Redraw rule for the next class | reject NAF sum under 163 (cost under 211), redraw from the next stream values | cost A at most 205, or k >= 1, or the eight ROT equal: continue the same SplitMix64 stream and draw the forty again | adv-mixer-2's form and numbers | + +Verdict unchanged: PASS against class v4 on the DSP-bound reading (M2 and model C agree at 0), the LUT tail bounded +and measured; the agreed numbers above replace this record's M1 figures wherever quoted, and AP-F4-1's rule on the +v5 list takes adv-mixer-2's form.

Result: the worst of 100,000 class v4 programs on the half-core proxy is 8.708 ms, +1.29 ms under the gate; the genesis program reads 8.624 on the same proxy, so the worst drawn program costs 1 percent +more than the genesis one and the distribution is tight (one-core clean rows 4.610 to 6.194 ms, p99 5.606). +Verdict: PASS.

The re-roll is possible ONLY when the adversary can evaluate the draw of a candidate input +inside the block publish window. Today the node has no VDF: `E_n` is a plain block hash, so the input of any candidate +block is known the instant the block is built, and the harness shows the last-block-before-the-cut is grindable with one +block of hash (1 of 6 cuts steered in fast time, `--vdf-ms 0`). With any delay past one honest block interval the +re-roll is gone (`--vdf-ms 5000`: 0 of 6). The design closes this with the 1-hour class-group VDF of spec 4.4: re-rolling +by withholding needs the 3,600 s VDF evaluated inside the 2 s window, a 1,800x evaluator, and spec 4.6's margin table +gives 300x as the horizon (`algorithm.md` 5.4; `sim/horizon/algorithm/model.py --section era`). The forge route needs +2/3 of the 30-day weight, 20 days of 100 percent hash (CLAUDE.md headline). The sub-row is INCOMPLETE because the harness +cannot demonstrate the real gate: the VDF and the certified checkpoint it reads are not in the node yet (era-layout.md +section 8 states this). What the harness DOES establish: the C_era cut rule with no delay is grindable, so the era draw's +soundness rests entirely on the VDF landing before the draw procedure is frozen, and the delay-soundness measurement is +owed to the finality lane. + +## (b) The 2^20 era-seed census (hash lane) + +`tools/attack/f7-era/` (a cargo crate with `igneum-pow` as a path dependency and an empty `[workspace]`; ELF built on the +box, sha256 `a87818d8...`). `attack-f7 census` runs `era_draw` over `V3_ALLOWED` on `2^n` seeds and classifies each draw; +`attack-f7 all` runs the plant known-fail case, the census, the spec-stream op-weight census and the day-key check. + +Known-fail / known-pass of the classifier (planted parameters through a test hook in this crate; log +`/srv/builds/igneum-wt-attack/attack-f7/census-2p20.log`): every planted weak draw fires its flag (M = 1, M = 2^32-1, +M = 2^16+1, a naf-2 multiplier, an even M, R = 0, R = 32, pos linear, pos contiguous, pos not ascending) and a sound draw +(igneum-era-test/0) raises nothing.

Against a flat +uniform the 64-item buckets of p2 (a program without the finding) read +10.03 and -9.06 sigma, which is the window +layer and not a flaw. The item tests are therefore judged against the **window-weighted null**: the expected count of +every item from the program's 16 windows, and a control that draws each read from a uniformly chosen site's window. +A chip gains nothing from the window steps: the union of the windows is the whole dataset every hour (era-layout.md +section 7), the floor window is 2^26 words (256 MiB), and which quarter is dense changes with the program. + +#### The window model (reproducible by any reader) + +For load site s with window draw `(k_s, o_s)` at the 2^28-word dataset: `k = min(k_s, 28 - 26)`, the word window is +`[o_s << (28 - k), (o_s + 1) << (28 - k))`; the item window is `[o_s << (24 - k), (o_s + 1) << (24 - k))` of +`2^(24 - k)` items (the four interleave positions all lie below bit 16, so the top bits of the word index are the top +bits of the item index). The expected reads per item is `E[t] = sum over sites s with t in window_s of N x 8 / 2^(24 - k_s)` +for N nonces (8 iterations per site), a density constant on each quarter of the item space. The windowed control draws +each of the N x 128 reads as (site = read index mod 16, item uniform on that site's window). Both controls are drawn from +SplitMix64 with a fixed seed. The tests on items are run against E[t] (chi-square, sigma of the largest and smallest +64-item bucket) and against the windowed control (the top-f shares); the flat uniform numbers are kept beside them as +what an auditor sees first. + +#### Results, 10^6 nonces per program, 128,000,000 reads (`log/e-warps-p{1,2,3}-1e6.log`) + +| Program | Windows (k_off:offset per site) | Quarter densities (reads per item) | Buckets64 largest sigma, windowed (control) | chi2/dof windowed (control) | Top 0.1% share: real / window control / flat control | Ratio to window control at 0.1% (gate 1.2x) | Ratio to flat control | Hot set (X_f >= f) | +|---|---|---|---|---|---|---|---|---| +| p1 devnet epoch 0 | 2:1 1:1 1:1 1:1 0 1:1 0 2:2 1:1 1:1 2:0 0 0 0 2:0 1:1 | 6.20 / 4.29 / 10.97 / 9.06 | +45.77 (+4.95) | 1.2336 (0.9981) | 0.5458% / 0.2891% / 0.2429% | 1.888x BEYOND | 2.247x | yes at 0.1% (X/f 2.57) and 0.5% (1.20); not at 1% (0.46) | +| p2 | 2:0 1:0 0 0 2:3 2:2 1:0 0 2:3 0 0 0 0 1:1 2:0 0 | 9.54 / 5.72 / 6.68 / 8.58 | +4.59 (+4.64) | 1.0061 (0.9986) | 0.2716% / 0.2639% / 0.2429% | 1.029x within | 1.118x | no (X/f 0.08, 0.05, 0.05) | +| p3 | 1:0 0 0 2:2 0 0 1:0 1:0 1:0 2:2 2:2 1:1 0 0 0 0 | 7.63 / 7.63 / 10.49 / 4.77 | +12,245.66 (+5.06) | 907.67 (0.9993) | 4.5954% / 0.2792% / 0.2433% | 16.46x BEYOND | 18.92x | yes at every f (X/f 43.2, 9.9, 5.0) | + +p2 is what the class is designed to be: against the window model its largest bucket is +4.59 sigma (the control +4.64), +chi2/dof 1.006, the top 0.1% of items hold 1.029x their window-model share, and the flat-control ratio of 1.118x is +the window layer. p1 and p3 are the finding (section 5).

The site then reads one word, `rotl(0xffffffff x M, R) & window | offset` = 0x0ca59e4c for a full +window and 0x04a59e4c, 0x08a59e4c, ... for the windowed sites; near-all-ones values add a few hundred more. The +same word family appears in every flagged program (seeds 4,000,001, 4,000,037, 4,000,040 in the selftest: `or` +writes at 54 and 55 before the load at 60, or at 1 before the load at 3). Rule (c) does not see it: the saturation +test counts final register values only (the register is overwritten before the end), the lane-constant test needs +all 32 lanes equal, the distinct test counts per lane per hash (the hot word repeats across iterations, so it +costs one distinct of 128), and the output bias stays within tolerance. The 3 October census measured an +`or_sat_frac` per program (section 7.3, max 0.0102) but the adopted rule kept only the final-value count. + +What it is worth to an attacker: nothing asymmetric. The hot words are the same for every lane that saturates, so +the GPU's coalescer and L1 already serve them without a DRAM transaction, and a chip gets exactly the same. What it +costs the design: those programs do fewer memory-hard reads than rule (c) promises (up to 10 percent fewer on the +worst program in 2,000, at least 1 percent fewer on about 1 program in 100), so the per-hash memory work of class +v4 is not the uniform 128 random reads the chip model assumes on every epoch. Gate reading: FAIL in the strict +reading (zero passing programs with a hot set under 1 percent of items), FAIL in the share reading too (programs +with a hot set capturing at least 1 percent of reads exist at about 1 percent of epochs). Proposed fix, for the hash +lane (not applied here): a per-site line in rule (c), "every load site reads at least 2,000 distinct addresses over +the 2,048 evaluations" (uniform gives 2,048 minus 0.008 expected repeats; the saturated sites read 434 to 1,855), +computed from the addresses the test already collects (one sort of 2,048 per site, 128 sites, under a millisecond); +the redraw rate rises by about the strict-reading fraction (8 percent of candidates) unless the threshold is placed +at the share reading. The alternative, dropping the `or` family from the draw table, changes the frozen weights and +is for the lane to weigh. Class check: a chip gains nothing today, but a stand-in that lets 1 percent of epochs run +with a 1 to 10 percent lighter memory side is a published-number problem (evidence row 17's per-hash reads). + +(the 10^6 numbers and the hot-share distribution replace the sample when the census ends) + +## Sub-row (c): header grinding + +### What an attacker can steer + +Only a load whose address register has not yet absorbed a dataset word is a function of the init words and the +nonce alone (taint analysis, `init_determined_sites`). On the devnet epoch-0 program these are the loads at +instructions 7, 8, 9, 10 and 31 of iteration 0; from iteration 1 every register is tainted.

The exact pebbling optimum for the chain (dynamic programming, checked against exhaustive search at 10 to 16 lines) sits under that curve: blocks per read 16.0 against 31.5 at f = 1/64 (the one held line belongs at line 32, not line 0), 10.5 against 15.5 at 2/64, 6.09 against 7.5 at 4/64, 3.17 against 3.5 at 8/64, 1.45 against 1.5 at 16/64, equal from f = 1/2. So a chip holding 1/64 of the cache pays 9.3x the item's ops, not 17.4x; at f = 1/2 and above nothing moves, and the SRAM column and the full-store verdict stand (no point on the curve beats the full store under the op budget or under energy). Memory-bound rate = the ceiling / (128 f). Compute-bound rate = 50 T op/s / ops per hash (the section 1 budget). + +Second correction, 8 October 2026 (the in-house adversarial pass, lane adv-cache-2, report section 2.3 and its Q3(3) window-layer reading, tip 3f50d6c4): the partial-store rows model a chip that holds a fraction f of the ITEMS chosen uniformly, so it serves f of the reads and recomputes 1 - f. The item-read distribution is not uniform: the exact window-layer distribution (matching the 4,096-program census to four digits; top quarter mean 0.3382, top half 0.5811 of reads) lets a chip holding the hottest f of items serve 0.4219, 0.7188 and 0.8907 of reads at f = 0.25, 0.5 and 0.75 on the measured programs, so the f = 0.25 and f = 0.5 rows overstate the recompute share by up to 2.3x (1.8x on the first shard's read) and the f = 0.75 row by about 2.3x on the miss side. The f = 1 row, the SRAM column and the full-store verdict do not move (a chip that holds everything recomputes nothing either way), and no served number rests on f under 1; the partial-store rows stay as the uniform-store bound with this note until the hottest-f rows are drawn from the window distribution, which is the next pass of this section.

(7 October 2026, 21:3x UK, the founder's question "we need a solution, deep research, other methods") + +The question: with class v5 (the dataset built from the chain's execution state, refreshed per window) and the latency-shadow work of class v4 set to zero (class v3 energy on every GPU), what edge does the strongest chip keep over an RTX 5090 per joule? If it were at or under about 2x the shadow could come off after v5 and the class v4 premium (145 W on a 5090 at the unlocked core, 88 W at the 1,400 MHz lock, measured 7 October 2026) would vanish. + +What class v5 changes for the chip, from `docs/design/class-v5-stored-state.md` sections 2 and 2a: the recompute chip (`f = 0`, the dataset derived on the fly from the cache) and the stateless or stale chip are removed as categories, because every item takes a leaf of the state and the leaves refresh every window. What it does NOT change: the strongest chip was never one of those. It is the `f = 1` stored-dataset chip of 5.5, a GPU's memory system without the GPU, and under class v5 it needs one thing more, the window's leaves, which section 2a.2 prices honestly: one node serves a whole farm, the leaves ship at 16.5 KB/s to 10,000 members today (45 MB per member per window over a 1 Gbit/s WAN before the state is 7,500x today's), and the rebuild on the chip is the same 32 ms per window every GPU pays. The dataset is still derived from a seed and the state, so a central node compresses everything but the state's bytes, and the chip stores the result as before. + +The arithmetic, on the model's own figures (5.3: the activate-bound ceilings, 2.0 nJ per random read on GDDR7 and 1.2 nJ on HBM3, the static and controller watts; the 5090 at 136.1 MH/s on 326 W, 0.417 MH/W; 128 loads per hash, the shadow at zero so no ALU beside the memory). The node is a desktop-class CPU with an NVMe and 32 GB at about 85 W (approximate, from memory of such machines; a full node with the EVM executor at 1 block/s), shared by a farm (100 chips: 0.85 W each) or carried by every chip (the attacker's worst case, 85 W each). + +| Chip, class v5 on, shadow at zero | MH/s (model) | W with a farm-shared node (0.85 W) | MH/W | Edge over the 5090 per joule | W with a node per chip (85 W) | Edge | +|---|---|---|---|---|---|---| +| GDDR7 `f = 1`, 16 devices (the 5090's own memory without the GPU) | 166 | 78 | 2.12 | 5.1x | 163 | 2.5x | +| HBM3 `f = 1`, one stack | 84 | 28 | 3.02 | 7.2x | 112 | 1.8x | +| HBM3 `f = 1`, eight stacks (an H100-class package) | 666 | 175 | 3.80 | 9.1x | 259 | 6.2x | + +Every figure is modelled (arithmetic on cited memory figures, approximate where 5.3 marks it); none is measured; the node's watts are an approximate from memory. + +Reading: NO. Class v5 with the shadow at zero leaves the strongest chip at 5.1x (GDDR7) to 9.1x (HBM3, eight stacks) per joule, the class v3 figures of 5.6 less a rounding, because the node is a farm cost and not a chip cost; only a chip forced to carry its own node falls near 2x, and only the small ones (one HBM3 stack at 1.8x, the GDDR7 board at 2.5x), while the eight-stack package stays at 6.2x even with a node per chip. So the shadow (class v4's 100,000 ops per hash in the memory wait, which brings the chip to 2.1x at k = 1 and 3.9x on the claimed X9 core) stays the only lever in this model that reaches the memory-system chip, and the class v4 premium is the price of that lever on today's GPUs. What class v5 buys is different and real: the recompute chip and the stale chip are gone as categories, every miner must hold and follow the chain, and a chip's dataset is wrong the moment its node is. The premium itself has two measured levers tonight: the core-clock lock (57 of 145 W back on the 5090 at 1,400 MHz for 1.4 percent of rate; the knee below 1,400 is the second pass's) and the per-card tune the app lands by itself; what would remove it is a shadow whose work is cheaper per op on a GPU than on a chip core (the research lane's question: a shadow shaped for the GPU's idle datapath at low clock, or a memory-side cost the chip cannot amortise), not the state-derived dataset. + +Per tier: a miner on class v4 pays the premium and gets the 2.1x to 3.9x chip ceiling in exchange; on class v5 with the shadow kept the ceiling stays and the dataset is the chain's; on class v5 with the shadow dropped the premium goes and the ceiling returns to 5x to 9x. The decision is the founder's; this section gives the number. + +### 5.11 Two columns from the counter-asic-4 research file (7 October 2026, 22:3x UK; `docs/analysis/counter-asic-4-research.md` sections 15 to 19 at bca23f96, the research lane's reading, carried here as the chip model's own columns) + +The k column. k is the chip core's energy per op over the GPU's at the same operating point, and the model's 3.4x row takes k about 0.33 for an ALU-shaped core. On the public figures the int8 tensor tile is the one GPU block whose energy per op a chip at the same node cannot undercut with certainty: the 4090 measures 0.056 pJ per MAC; NVIDIA's 5 nm INT4 test chip reads 0.021 pJ per MAC at 0.46 V and about 0.1 at nominal (JSSC 2023, via Dally's NASEM slides; claimed), so INT8 at 2x to 4x that gives k 0.7 to 3 with the centre near 1; every ALU-shaped block reads k 0.3 to 0.8 on the same sources. A shadow built of tensor tiles at the ALU shadow's premium (about 11,400 u8 tiles per hash) therefore gives 2.1x at k = 1 and 1.6x at k = 1.5 and removes the k 0.3 column from the table; it needs a SIMD byte-dot verifier (the scalar one at 12.4 ms fails the 10 ms gate). This is a design candidate, not the shipped stream: the shipped shadow is ALU-shaped and its row stays 2.1x at k = 1 and 3.4x at k about 0.33. + +Correction, 8 October 2026 (the research lane's microbench on the 5090, counter-asic-4-research.md 15.1a and the corrected 20.3 and 20.4 at 71fd465b): the per-MAC figures above are wrong by a factor of 32. A `mma.m8n8k16` tile is 1,024 multiply-adds per warp, 32 per lane, so a hash does 32 MACs per tile, not 1,024; the 4090's "0.056 pJ per MAC" is 1.8 pJ, and the 5090 at the ALU shadow's premium reads 2.9 pJ per MAC unlocked and 1.5 pJ at the 1,300 MHz lock (the packs job, 366,080 MACs per hash; the microbench's dependent u8 tile 4.1 and 2.2, the wide s8 m16n8k32 tile 1.36 and 0.83). Against the same 5 nm MAC array figures (0.04 to 0.4 pJ per INT8-class MAC, claimed) a chip's k on tile work is therefore 0.03 to 0.3, below the ALU shadow's 0.3 to 0.8, not near 1: at the same premium a tensor-shaped shadow leaves the chip 3.5x to 6.7x where the ALU shadow leaves it 2.1x to 3.5x. The tensor-tile column (2.1x at k = 1, 1.6x at k = 1.5) is withdrawn as a candidate; its premise, that a chip's MAC is no cheaper than the GPU's, is false by 4x to 30x on the public figures. The shipped row is unchanged: 2.1x at k = 1 and 3.4x at k about 0.33, the ALU shadow at the operating point's knee, measured four times at 82 to 90 W. + +The capex column. The `f = 1` GDDR7 chip of 5.5 is USD 2.8 per MH/s of silicon and memory, which is USD 0.00016 per MH/s-hour of capex over two years against USD 0.000023 of electricity: capex-dominated 7x, as the 5090 is (USD 14.7 per MH/s at MSRP, 10x). A 64 MiB hot table adds about USD 15 of N5 die, the shadow core USD 25 to 40, an interposer USD 200, so the chip's capex reaches at most about USD 4.3 per MH/s: the per-unit capex wall is unreachable by 3x to 7x, and the break-even market cap moves only through the project cost (the mission lane's model: about USD 100 M with the N5 shadow core, about 200 M if the shadow runs per load and forces one die or an interposer; the per-load form behind that figure, the 16 x 27 placement, was closed on 7 October 2026 at night when it failed the value-level acceptance test across drawn eras, so the 200 M row rests on no construction shown to exist until a sound per-load class, one pass of a 432-instruction sub-block per load, is drawn, accepted and measured). Every figure here is modelled on cited or claimed parts; the research lane's microbench (20 probes, the mma_u8 and l2 rows the ones this model would take) is on PC 1's queue after the hot-table job. + ## 6.

The space is of order 2^80 before the per-site windows, which are per program. No census walks it. What a census can do is (i) draw eras from the chain's own distribution (the era stream over random `E_n`) and bound the fraction of eras that fail a test (section 2.1), and (ii) pin the axes that carry a KNOWN mechanism at their corner and draw the rest (section 2.3), so a mechanism that depends on one named axis is read at its worst value.

The weights, the width and the shape are per-era axes and are what the drawn-era census of section 6 walks. + +## 2. The sampling bound + +### 2.1 Zero failures in `n` eras (the rule of three, Wilks) + +Let a per-era test have a fixed verdict per era and let `p` be the fraction of the family's eras (under the chain's own draw) that fail it. If `n` eras drawn independently from that draw all pass, then with confidence `1 - alpha`, `p <= eps` where `(1 - eps)^n = alpha`, that is `n >= ln(alpha) / ln(1 - eps)`, about `3 / eps` at 95 percent and `4.6 / eps` at 99 percent (Hanley and Lippman-Hand 1983; Wilks 1941 gives the same arithmetic as the one-sided nonparametric tolerance limit on the worst order statistic). The table, with the era length of layer 3 (180 days) turned into years: + +| `eps` (the failing fraction bounded) | One failing era expected every | `n` at 95 percent | `n` at 99 percent | +|---|---|---|---| +| 1/16 | 8 years | 45 | 70 | +| 1/64 | 32 years | 190 | 293 | +| 1/256 | 126 years | 766 | 1,177 | +| 2^-10 | 505 years | 3,067 | 4,713 | +| 2^-20 | the F4 and F7 gate's fraction | 3.1 million | 4.8 million | + +What this buys and does not. The F4 and F7 gates ask "no class with gain over 1.1x at a fraction over 2^-20" and reach it by censusing 2^24 draws of a CHEAP statistic (microseconds per day key or era seed). A per-era test that costs box-hours (the F8 census at 2^24) can be run on hundreds of eras, so it bounds the failing fraction at the 1/64 to 1/256 class, never 2^-20. That is why layer 4 puts the tests on the chain: a per-era test the chain runs on EVERY era (ring A) or every epoch (ring B) needs no sampling bound at all; the offline census (ring C) is then a check on the chain-run tests' calibration (their clean refuse rate and their known-failed firing per stratum), and a reading of the one statistic the chain cannot afford, the live-dataset census. + +### 2.2 The union bound over the per-era tests + +Let the chain run tests `T_1 .. T_k` on every era or epoch, and let `delta_i` be the probability that `T_i` passes an era (or program) that carries the failure class `T_i` exists for. The family's false-pass rate on the union of those classes is at most `sum delta_i`. Each `delta_i` is itself bounded by the rule of three on the test's known-failed cases: a test that fired on `f` of `f` known-failed cases has `delta_i <= 3 / f` at 95 percent. The numbers today: + +| Test | Known-failed cases it fired on | `delta` at 95 percent | Source | +|---|---|---|---| +| (c''') floor at 0.995 on the few-item hot-set class | 9 of 9 live hot sets refused (minimum sites 0.9809 to 0.9919), both single-item programs refused | under 0.33 | adv-accept, "the floor's final tally", 01:13 BST 8 October; class-v5 section 14 | +| (c'') floor at 0.98 on the low-entropy band | 5 of 5 (p23, p18, p19, p15, p56) | under 0.60 | attack-pass-2026-10.md, sub-version 3 | +| (a') freshness on the lineage-visible constant class | 11 of 11 (sub-version 1's eleven seeds under 1.2x on sub-version 3) | under 0.27 | attack-pass-2026-10.md, the sub-version 1 table | +| The bucket bound (in sigma of the bucket's expectation at 2^20) on the quarter-bit class | 4 of 4 would be caught (p4, p8, p10, p34: largest bucket 3.1x to 5.6x at narrow windows, +17 to +37 sigma), not yet wired as a rule | under 0.75 once wired; the clean spread is measured in section 6 | the hash lane's attribution, 09:46 BST 8 October | +| The index-bit bias read on the product class | 3 of 3 named sites (Devnet 3 site 0 at P(bit 0) = 0.25; era-drawn-28 site 15 at 0.778; the per-load candidate 0 at z 29.5), and 7 of 7 in the 16-era smoke run at 130 to 511 sigma | under 0.30 on ten cases; but the read is a record, not a refusal (section 3.2) | adv-cache-2 2.3; counter-asic-4-research.md 20.2a; section 6 | +| The day-key cost rule | the planted mul1all and mulnaf days, day 29,337 | 0 of 2^24 days over 1.1x after the rule (a census, not a case count) | f4-weakday.md, 8ca66afa | + +Reading: the per-test miss rates are bounded by HANDFULS of known cases, so the union bound today is a loose number (the sum exceeds 1). The way to tighten it is not more eras but more known-failed cases per test, which the adversarial sweeps supply cheaply: adv-accept's tail holds 22 programs beyond the 1.2x gate of 37 measured live, and the drawn-era census of adv-cache-2 holds 19 biased sites of 1,056. A test with 60 fired cases has `delta` under 0.05; with 300, under 0.01. The proof of testing (section 4.3) therefore carries, per test, the count of known-failed cases it fired on, and that count is the number a reader checks first. + +### 2.3 Stratified draws over the corners + +The axes with a known mechanism and their corner values: `m` in {4, 16} (margin, verifier), weights at the lossy cap (or, mul, mulhi at +B) and at the table, `W` in {1, 4}, shape in {64, 256}, R in {1..27} against {28..31} (the product-bias class visible or hidden; at D = 29 the hidden set is {30, 31}), the windows forced to quarter (`k_off = 2` at every site, the F8 tail class), D in {28, 29}. That is 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128 corner cells for the per-era statistics (the mixer cells are per-family rows), plus the random stratum (every axis drawn). The plan: at least 8 eras per cell for the cheap ring-B statistics (1,024 eras, about 2 core-hours each at the (c''') cost, 2,000 core-hours, 64 box-hours of 32-core slots) and the random stratum at 3,000 eras (the 2^-10 line of 2.1 at 95 percent for the ring-B tests, 6,000 core-hours, 190 box-hours); the live-dataset census at 2^24 on 64 seeds for 24 corner representatives and 64 random eras (88 eras at 45 to 95 core-hours each, about 6,000 core-hours, 190 box-hours).

Where a line beats every layer, +this file says so with the number. + +## 0. One page + +The reads are the hash. Under class v3 the RTX 5090 spends 2.40 microjoules per hash on 128 dependent reads, 18.8 nJ +per read all-in, and the memory system itself spends 2.0 nJ of that (chip-model-v3 5.3, modelled); the card's own +marginal per dependent DRAM read is 10.9 nJ unlocked and 8.7 nJ at the 1,300 MHz lock (measured 8 October 2026, +counter-asic-4-research 15.1a). Every chip in this file is a machine that pays the memory's nanojoule and not the +card's ten, plus whatever the shadow (the program work drawn into the memory wait) forces it to pay at `k` times the +GPU's cost per op. That identity does not change with any technology below; what changes is the memory's nanojoule, +the rate a chip can read at, what a GB costs, and who can buy it. + +**The three findings that change v6's design** + +1. **The strongest five-year chip is not a DRAM chip. It is a 2 GiB SRAM full store on one reticle of merchant N2, and + none of the four layers reaches it.** TSMC N2 reads 38 Mb/mm^2 of SRAM (claimed, IEEE Spectrum, 12 December 2024, + volume in 2025), so 2 GiB is about 452 mm^2 of macro, one die under the 858 mm^2 reticle, roughly USD 400 to 600 of + silicon at a USD 30,000 wafer (approximate). It has no activate ceiling, so its rate is power-bound: about 2,100 + MH/s at 300 W, 0.14 microjoules per hash, **13x to 17x the 5090 per joule at zero shadow and about USD 0.3 per + MH/s** against the 5090's 14.7 and the GDDR7 chip's 2.8 (modelled; the wire energy, 0.5 to 2.0 nJ per read, is the + sensitivity). Layer 2's floor moves its capex, not its joules: at 4 GiB it is two dies, at 8 GiB four, USD 1,000 to + 2,500 of silicon, and its edge per joule falls only from 17x to about 13x because an inter-die hop costs 0.27 nJ + (UCIe, claimed 0.5 pJ/bit). A floor that would blunt it on joules (16 to 32 GiB, eight to sixteen reticles) retires + every honest card under 32 GB first. The only lever that reaches it is the shadow at `k`: with the shadow core on + the same N2 die the ALU band is 0.3 to 0.8 (the record's), and the class v4 premium holds **4.8x at k = 0.5, 2.7x + at k = 1**; at the 5090's whole ALU budget (about 330,000 ops per hash, 575 W) 3.7x and 2.0x. The design change: + layer 1's program-length draw is sized against this chip, not the GDDR7 board, with its lower bound at the shadow + that holds the record's 2.1x today and its upper bound at the honest cards' full latency shadow, re-based every + family epoch (layer 3) on the cards then mining; and the public "2x" line is not reachable in this model against + this chip at any `k` under 1. What slows it is money and time (an N2 project, USD 100 M to 500 M and 18 to 24 + months, approximate), which is the clock of Counter ASIC 3.0 item 4, not a hash property. + +2. **Per-bank processing-in-memory is structurally blind to this hash; the real near-memory threat is the custom + HBM4E base die, and layers 1 to 4 do nothing to it.** HBM-PIM, AiM, LPDDR5X-PIM and UPMEM put a compute unit beside + each bank (or a DPU per 64 MB); a dependent read's next address is uniform over the dataset, so it lands in the same + bank with probability bank bytes over dataset bytes: **1.6 percent at 2 GiB on a 32 MB bank, 0.4 percent at 8 + GiB**, and UPMEM has "no direct communication channel among DPUs" (claimed, the PrIM paper), so the other 98 + percent of reads go to the host. The unit that can follow the chain across banks is a controller on the stack's + base die, which is exactly what TSMC's custom C-HBM4E is: "the custom base die will integrate memory controllers and + PHY" on N3P at 0.75 V, "2x the power efficiency", Micron production 2027, SK hynix HBM4E in 2026 (claimed, + TrendForce, 1 December 2025). That is the `f = 1` chip of the record with its controller moved into the stack: about + 0.9 to 1.0 nJ per read, and HBM4's 32 channels (JEDEC JESD270-4, April 2025) double the activate-bound ceiling per + stack, so **6.5x to 14x per joule at zero shadow** (the ceiling unmeasured, as the record's HBM rows are). The four + layers act on the program, the item map and the capacity; this chip runs any program and holds 36 to 64 GB. What + brakes it until about 2028 is availability (HBM allocated to AI, 20 to 26 week leads, Samsung asking USD 4 to 5 per + Gbit for HBM4 against 1.5 for HBM3E, October 2026) and the shadow at `k`: 4.4x at k = 0.5, 2.6x at k = 1. + +3. **The denominator is the wrong card.** Every chip edge in the record is quoted against the 5090 at 2.40 microjoules. + The Apple M5 Max measured 0.78 microjoules per hash at the GPU-plus-DRAM meter (latency-shadow-2026-10-06, 6 + October 2026), 3.1x the 5090 per joule, and LPDDR6 SoCs (JEDEC JESD209-6, 2025; 14.4 Gbps, 32-byte atoms) are that + tier's next step. Against the M5 Max the GDDR7 chip reads 1.7x, one HBM3 stack 2.4x, the HBM4 base die 3.6x to + 4.4x, the N2 SRAM die about 5x, and with the shadow at k = 0.5 the SRAM die reads about 3x. The honest joule, not + the 5090's, is the chain's resistance, and the same chips are 2x to 3x less frightening against it. The design + change: v6's acceptance floor (layer 4) and the shadow sizing (layer 1) are scored per card tier with the + unified-memory SoC tier as the reference joule, the dataset is kept inside 16 GB unified memory (8 GiB at the top of + the schedule does that), and the public text states the edge over the best honest joule, which is the number a + miner can act on. + +The honest line, in one sentence: five years out a 2 to 8 GiB dataset fits in one to four reticles of merchant SRAM at +USD 500 to 2,500 of silicon, every DRAM line converges on the same 0.5 to 1.0 nJ per read with its controller in the +stack, and no layer of the four touches either; the shadow at the measured `k` band holds 3x to 5x, the honest tier's +own efficiency halves that again, and the clock (project cost against daily issuance) is the wall that is left. + +## 1.

The lines in detail + +### 4.1 Processing-in-memory and processing-near-memory + +Samsung's HBM-PIM (Aquabolt-XL, February 2021) places a programmable computing unit inside each bank of an HBM2 stack +and reports 2.5x system performance and over 60 percent energy saved on a Xilinx Alveo host (claimed, Samsung, 24 +August 2021). SK hynix's GDDR6-AiM (February 2022) adds compute to a 16 Gbps GDDR6 die at 1.25 V, claims up to 16x on +some AI operations and 80 percent less power, and the AiMX card (2023) carries 32 GB of it (claimed, SK hynix). Samsung's +LPDDR5X-PIM (Hot Chips, 25 August 2026) reaches 614 GB/s inside the package against 76.8 GB/s over the external +interface at LPDDR5X-9600, 3x the tokens per second on Llama 3.1 8B, with mass production "as early as 2027" and +LPDDR6-PIM in JEDEC work (claimed, TrendForce and Sammyfans, 25 to 26 August 2026). UPMEM's DPU-in-DRAM ships: 128 +DPUs per 8 GB DIMM, 64 MB per DPU, 350 MHz, MRAM reached only by DMA with a fixed cost plus a per-byte cost and at most +628 MB/s per DPU for 2,048-byte transfers, and "there is no direct communication channel among DPUs" (claimed, the PrIM +characterisation paper, arXiv 2105.03814, read 8 October 2026). The academic line (IMPICA, ICCD 2016: a pointer-chasing +engine on a 3D stack's logic layer, 1.2x to 1.9x and 10 to 41 percent less energy on linked lists, hash tables and +B-trees, claimed) puts the chaser on the base die, not in the bank, for the same reason this hash defeats the bank +units: the next address is anywhere. + +What it does to the chip's cost per dependent read: nothing good for the attacker at the bank level. The PIM unit's +arithmetic is the wrong kind (FP16 SIMD, not 32-bit integer ARX) and the wrong place: with uniform addresses the chain +leaves the bank after one read with probability 1 minus bank bytes over dataset bytes (98.4 percent at 2 GiB on a 32 MB +bank), and in UPMEM's case leaves the DPU with no path but the host. The near-memory version (a chaser with its own +controller on the base die) is the record's `f = 1` chip, and that is where PNM becomes real: see 4.2. + +Blunted by: layer 2, by the dataset's size alone. k: none (no path). + +### 4.2 HBM3E, HBM4 and the custom base die + +JEDEC's JESD270-4 (16 April 2025; read via eeNews Europe, 18 April 2025, and the search summaries, the Business Wire +and All About Circuits pages refusing the fetch) doubles the channel count to 32 with two pseudo-channels each on a +2,048-bit interface at up to 8 Gbps, 2 TB/s per stack, 4 to 16-high stacks of 24 or 32 Gbit dies up to 64 GB, VDDQ 0.7 +to 0.9 V and VDDC 1.0 to 1.05 V (claimed). TSMC builds the standard HBM4 base die on N12 at 0.8 V for "roughly 1.5x" +efficiency and the custom C-HBM4E base die on N3P at 0.75 V for "2x the power efficiency of today's DRAM +manufacturing", and "the custom base die will integrate memory controllers and PHY components typically housed +separately"; Micron targets 2027 production, SK hynix a first tailored HBM4E in the second half of 2026 with 12 nm for +mainstream and 3 nm for NVIDIA and Google premium designs, Samsung 4 nm now and 2 nm for custom HBM (claimed, +TrendForce, 1 December 2025 and 23 January 2026). Prices: HBM2e USD 120 per 16 GB, HBM3 200 per 24, HBM3E 300 per 36, +HBM4 about 550 per 36 (estimate), factory gate, with contract about 2x and 20 to 26 week leads (claimed, Silicon +Analysts, October 2026); Samsung is asking "mid-to-high $4 per gigabit" for 2027 HBM4 against about 1.5 for HBM3E +(claimed, Sammyfans, 2 October 2026). + +What it does to the chip's cost per read: the row activation (909 pJ per 1 KB row, HBM2, O'Connor Table 3) does not +move; the movement and I/O terms fall with the voltage and the base-die node; a 32-channel stack doubles the activate +parallelism the record's HBM rows are bound by (10.7 G reads per second per HBM3 stack, unmeasured; 2.3 G at the JEDEC +tFAW). The arithmetic on the record's method: HBM4 1.0 to 1.1 nJ per read and 21.3 G reads per second per stack (166 +MH/s at about 36 W, 0.22 microjoules, 11x; at the JEDEC-tFAW ceiling 36 MH/s at 19 W, 0.53, 4.5x); the custom base die +0.9 to 1.0 nJ with its controller inside (166 MH/s at 29 W, 0.18, 14x; 6.5x at the low ceiling). The latency stays in +the 45 to 50 ns class; the capacity (36 to 64 GB) is 4x to 8x any floor layer 2 could set without retiring the honest +cards. + +Who can buy it: through 2027 the stacks are allocated to AI accelerators at Tier-1 volume terms; a custom base die is a +per-customer engagement with the DRAM maker. A chip maker of Bitmain's or Canaan's size (the history's rows: tape-outs +on 7 nm-class nodes, R&D in the tens of millions of dollars a year) could commission one from 2028 (approximate); a +USD 5 M startup cannot. The brake is money and queue, not physics, and it expires. + +Blunted by: nothing among the four. The shadow at `k` = 0.5 holds 4.4x, at `k` = 1 2.6x; the shadow core is logic on +the N3P base die and sits at the band's low end against a GPU on an older node. + +### 4.3 LPDDR6 + +JESD209-6 (2025) gives 10,667 to 14,400 MT/s on a 24-bit channel split into two 12-bit sub-channels, a 32-byte minimum +access with 32 and 64-byte bursts, 4 to 64 Gb dies, lower voltages than LPDDR5, a dynamic efficiency mode and on-die +ECC (claimed, JEDEC via PCWorld, HotHardware and MicrocontrollerTips, 2025). The bank count per channel and the tFAW +are not in the public summaries read (unverified); LPDDR5's 16 banks per channel and a tFAW near 20 ns are the +assumption (approximate). A 32-channel, 64-sub-channel controller chip then reads about 12.8 G dependent reads per +second (approximate), 100 MH/s, at 1.5 to 2.0 nJ per read: about 4x to 5x the 5090 per joule, the GDDR7 board's class +at a lower price per channel. The dies are the cheapest random-access memory a non-hyperscaler can buy outside the +2026 price cycle (USD 3 to 4 per GB in 2024, approximate; USD 8 to 21 in 2026 LTAs, claimed). + +The point of this line is not the chip. The M5 Max already is an LPDDR5X part with a GPU, at 0.78 microjoules per hash +measured at the GPU-plus-DRAM meter, 3.1x the 5090 per joule; the Windows-class LPDDR5X SoCs (NVIDIA's and Qualcomm's +desktop parts, approximate) and the LPDDR6 generation after them are the honest tier's floor. A controller chip on the +same memory beats that tier by 1.3x to 1.6x at zero shadow. The resistance of the chain is set by this tier, and v6 +should say so (finding 3). + +Blunted by: none needed. + +### 4.4 3D DRAM + +Samsung's VS-DRAM (VLSI 2023), 16 stacked layers demonstrated against Micron's 8, VCT 4F2 cells as the stepping stone +with prototypes in 2025 and commercial 3D DRAM "by approximately 2030"; Neo Semiconductor's 3D X-DRAM at 230 layers +and 128 Gbit per die as a concept (claimed, heise 29 May 2024, Yole, ComputerBase). No source read claims a latency or +activate-rate change; the gain is capacity per area (about 3x). For a chip that reads 1 to 8 GiB at random, capacity +per die is not the constraint (channels are), so 3D DRAM lowers the honest card's and the chip's cost per GB alike and +changes no row. Outside the five-year edge. + +### 4.5 CXL memory pools + +CXL 2.0 expanders on Xeon 6 measure 100 to 160 ns against 75 ns local DDR5; a CXL 3.1 controller adds about 70 ns; +pooled DDR5 was USD 4 to 7 per GB before the 2026 cycle (claimed, Introl, 1 February 2026, and the search summaries). +A dependent chain through a host CPU and a PCIe-class link at 64 bytes per transaction is bound by the link's +transaction rate (about 500 M per second per x8 device at about 25 W, approximate): 0.4x the 5090 per watt. A capacity +tool. No edge, no layer needed. + +### 4.6 Wafer-scale + +The WSE-3 holds 44 GB of SRAM at 21 PB/s across 900,000 cores on 46,225 mm^2 of N5; the CS-3 draws about 23 kW and +costs "maybe $2.5 million" (claimed, Cerebras and The Next Platform, 14 March 2024; the power from the search summaries). +A 2 GiB dataset spread over the wafer is read by a dependent chain whose next address is uniformly random across 215 +mm of mesh: the traffic is all-to-all, the mesh is bisection-bound, and the average reply crosses about 140 mm of wire. +At about 0.1 pJ per bit per mm (approximate) a 512-bit reply costs about 7 nJ before routers, 3x the GDDR7 board's +2.0; at about 950 links across the bisection at 32 bits per cycle and about 1 GHz (approximate), the wafer completes +about 110 G reads per second, 500 G with the dataset replicated twenty times in regions, 5 to 22 M reads per second per +watt against the 5090's 54 M. Per joule 0.1x to 0.4x, per dollar one thousandth. The wafer is a streaming machine; this +hash is not streaming. No layer needed; layer 2 removes the replicas as the dataset grows. + +### 4.7 Chiplets, interposers and optical I/O + +UCIe gives 0.25 to 0.5 pJ per bit by package type (claimed, UCIe consortium via SNIA SDC 2022 and 2025 pages); BoW 0.5 +to 0.7; CoWoS-S is USD 600 to 900 per H100-class package and a one-stack interposer about USD 200 (the record). A +read that crosses a die boundary pays about 0.27 nJ (544 bits at 0.5 pJ) and 5 to 10 ns, which is what makes the +multi-die SRAM chip of 4.9 cost 1.1 to 1.3 nJ per read instead of 1.0. Optical I/O (Ayar Labs' TeraPHY at about 5 pJ +per bit, UCIe-compliant, a USD 500 M round on 3 March 2026; Celestial AI's Photonic Fabric at 6.2 pJ per bit and about +120 ns round trip; claimed) is 6x to 8x the interposer's energy per bit and adds latency: it pools memory across +packages, which this traffic never wants. No row moves. + +### 4.8 FPGA with HBM + +The Alveo V80 (Versal XCV80, 32 GB HBM2e as two 16 GB stacks, 820 GB/s, 190 W, USD 9,495 MSRP, May 2024) and the U55C +(USD 4,747) are what a non-hyperscaler can buy today with HBM on it; Altera's Agilex 7 M-series carries the same two +HBM2e stacks at 820 GB/s (claimed, AMD, Wccftech, The Next Platform). The record's reading stands: an HBM2 stack under a +soft controller reaches the JEDEC tFAW ceiling, 2.3 to 2.4 G random reads per second (Shuhai, FCCM 2020, Figure 7), +so two stacks give about 4.8 G, about 37 MH/s at about 150 W (approximate), 0.6x the 5090 per joule at 5x its price. No +HBM3E FPGA was found announced in the pages read (unverified). No layer needed. + +### 4.9 SRAM at 2 nm: the full store on one reticle + +TSMC's N2 reads 38 Mb/mm^2 of high-density SRAM, 11 percent over N3E (claimed, IEEE Spectrum, 12 December 2024; +volume from 2025); wafers are about USD 30,000 and "booked to 2028" (claimed, tech-insider, 2026). The arithmetic: 2 +GiB is 17,180 Mbit, 452 mm^2 of macro; with periphery, a controller, the lanes' registers and a shadow core, a 550 to +650 mm^2 die under the 858 mm^2 reticle; about 95 gross dies per wafer, 55 to 70 percent good with row and column +repair (approximate), USD 400 to 600 of silicon. No DRAM, no interposer, an organic package. Under class v5 the +dataset's items are leaves of the chain state refreshed per window; the chip rewrites 2 GiB per window at on-die +bandwidth, the same 32 ms every GPU pays (the record, chip-model-v3 5.10), and holds a node or shares one across a farm +as the record prices. + +Energy per read: the macro's 64-byte read, about 0.1 nJ (approximate), plus the global wire. The record took 0.6 pJ per +bit of wire across a 128 mm^2 array; scaling with the side of the die gives about 1.3 pJ per bit across 600 mm^2, 0.68 +nJ for 512 bits, so about 1.0 nJ per read with the controller, range 0.5 to 2.0 (the sensitivity of every SRAM figure +here). Latency 10 to 20 ns. No activate ceiling, no tFAW, no refresh: the rate is power-bound. At 300 W with 30 W of +static and controller power: 270 W over 128 nJ per hash is about 2,100 MH/s per die, 0.14 microjoules per hash, 17x +the 5090 at zero shadow (13x at 1.3 nJ, 8x at 2.0, 30x at 0.5); USD 0.25 per MH/s of silicon, about 0.4 with the +board. Two dies at 4 GiB: half the reads cross one UCIe hop, 1.14 nJ, 15x, USD 1,000. Four dies at 8 GiB: 1.3 nJ, 13x, +USD 2,000 to 2,500, a 4-die organic package. The honest cards hold 8 GiB fine (16 GB and up); a floor that pushed the +dataset past what a package can hold (16 to 32 GiB, eight to sixteen reticles at USD 5,000 to 10,000 and 1.5 to 2.0 +nJ per read, still 7x to 9x) would retire every honest card under 32 GB first. Layer 2 therefore sets this chip's +capex and die count, not its joules, and the floor's number is a card-lifetime decision, not a chip decision. + +The project: the history's IBS figures (5 nm USD 416 M to 542 M, 3 nm 590 M) price an SoC; an SRAM array with a +controller and a sequencer core is simpler and the startup figure ("$50M to $75M" for 7 nm, SemiAnalysis) is the +better guide, so USD 100 M to 500 M at N2 (approximate) and 18 to 24 months to a first chip (approximate). That is the +clock of Counter ASIC 3.0 item 4 and the daily-issuance threshold of the history (chips at USD 20 K to 50 K of daily +issuance for compute-bound hashes; 32 months for Ethash at the largest prize): the SRAM chip arrives when the prize +pays for an N2 project, and nothing in the hash moves that date. + +Blunted by: layer 2 on capex only (USD 500 to 2,500 across the floor's range); the shadow at `k` on joules: with the +shadow core on the same N2 die against a GPU on N3 or N4 the ALU band sits at 0.3 to 0.5; at `F` = 1.10 the chip reads +4.8x at k = 0.5 and 2.7x at k = 1; at the 5090's whole latency shadow (about 330,000 ops per hash, `F` about 2.0, +575 W) 3.7x and 2.0x; against the M5 Max's joule about 3x at k = 0.5. + +### 4.10 RLDRAM and the activate-free line + +RLDRAM 3 (Micron, 2011; ISSI second-sourced) has a tRC under 10 ns, 16 banks per device, no separate activate +command and "SRAM-like random access" (claimed, Micron's product page and the 2011 announcements), in 576 Mb and 1.125 +Gb devices at up to 2,133 Mb/s (approximate). One device completes about 2 G random reads per second (16 banks over 8 +ns), six times a GDDR7 device's share of the 5090 board's 21.3 G; sixteen devices, 2 GiB, about 32 G reads per second, +250 MH/s per board. The energy per read is not published in anything read (a power calculator exists); a full +small-row access per read at an old node reads 2 to 4 nJ (approximate), so about 5x per joule, at USD 400 to 800 per +GB (approximate, a low-volume networking part). It is the proof that an activate-free DRAM exists, and AMD's "Folded +Banks" (ISCA 2025, with AMD Research: 8x the activate parallelism in a 3D-stacked HBM gives 6.7x the irregular +bandwidth, claimed from the abstract; the PDF refused the fetch) is the same idea on the HBM roadmap. If a DRAM maker +ships it in HBM, the activate ceilings in the record's HBM rows rise 6x to 8x and the HBM chip's rate per stack with +them; its energy per read falls by the row-size term (O'Connor's FGDRAM: 51 percent). That is the DRAM-on-logic row. + +Blunted by: layer 2 on RLDRAM's capacity cost (USD 3,000 to 6,000 at 8 GiB); nothing on the HBM version. + +## 5. The k bands for the research lane's chip rows + +For `docs/design/class-v6-rotating-family.md`. The shadow `k` is the chip core's energy per forced op over the GPU's +at the same operating point (the record's ALU band 0.3 to 0.8 on the 5090's measured 6.2 to 11.3 pJ per op); the +memory `k_read` is the technology's energy per dependent read over the 5090's measured 10.9 nJ.

The number v6 inherits is 5.1x per joule at zero premium (2.1x with the shadow at k = 1), and the lever is the honest card's operating point and the shadow's premium, not the draw. +2. **Automatic change beats the human fork only where it costs the chip a redesign, and the one parameter that does is the memory.** Grin's six-monthly tweaks held because each was a new algorithm the lane was scheduled to retire; Monero's forks lost on the second lap; Ethash's DAG growth is the one scheduled change in the record that killed a shipped chip (the E3, when the DAG passed its 4 GB of DDR3). Layer 2 is that lesson made a rule, and its rate decides everything: at 2 GiB plus 0.5 GiB a year a 32 GB chip board outlives the chain, so layer 2 as declared ages out the honest 8 GB card before any chip unless the floor is set against DRAM cost per gigabyte, not against chain state. +3. **A steered or biased address pattern is always found after launch unless the test lives in the acceptance rule, and every new draw needs its own null.** ProgPoW's seed, MTP's blocks and class v4's lossy sources were the same attack three times; layer 4 puts the test where it must be, and its cost is one census per era draw on the node (2.2 s per candidate at 2^20 today) with the null re-derived for every drawn parameter, because the window model that defines "uniform" changes with the read width and the program length. + +**What the history says to add** (section 5): a layer 2 floor and a per-tier ceiling stated before its rate (the synthesis lane has since made the ceiling layer 2's first constant); the issuance clock and the share-pattern detector (unchanged from the 5 October ranking, still unbuilt); the read width's draw band stopped where the honest card stops being latency-bound ({4 B, 16 B} on the measured warrant, nothing wider); the op-mix band bounded by the per-vendor energy table; the reserve ordered by what a sequencer chip cannot fold into firmware. + +## 1.

"typical DRAM energy dissipation is 3 to 4 pJ per bit" and "the energy expended to move data from DRAM to compute are the same for GPU or ASIC", so the shipping chips showed "about 1.6x hashrate per watt over GPUs" (E3 0.24, A10 0.57, the best overclocked GPU 0.40 MH/W in his table); integrating memory with logic cuts the movement energy "much more than 10x" to "under 0.3 pJ per bit", "the looming threat" (https://github.com/ethcatherders/progpow-audit, the PDF's text, read 8 October 2026). Ren and Devadas (TCC 2017) give the bound: memory hardness bounds area, not energy; the energy of a memory access is comparable on a chip and a CPU, so bandwidth hardness is the only energy lever (https://eprint.iacr.org/2017/225). The derived ladder at 65,536 bits a hash: pure memory energy caps Ethash at about 0.76 MH/J on DDR3, 2.8 on GDDR6 and 3.9 on HBM2 (O'Connor et al., MICRO 2017: HBM2 3.92 to 3.97 pJ per bit, GDDR5 14.0); the shipped chips sit at 0.24 (E3), 0.6 (Innosilicon), 0.9 (Linzhi), 1.25 to 1.67 (E9, E9 Pro) and 2.1 (Jasminer, by leaving commodity packaging). The cap was the memory's own energy per bit, and the one chip that beat it moved the memory onto the die's face. + +**The timeline.** Hash live July 2015; the E3 at 32 months (announced) and 36 (shipped); the first chip over 2x at 65 months (Linzhi, December 2020); 5x at 75 months (Jasminer, October 2021); the Merge at 86 (15 September 2022). The E3's death by DAG growth: Classic first, at epoch 328 (DAG about 3.56 GB, March 2020), then Ethereum, with a 30 March 2020 firmware stretching the DDR to about block 11.4 million (about October 2020): 20 to 27 months after shipping. Ethereum's responses: Zamfir's April 2018 poll (57 percent for an anti-chip fork); EIP-1057 created 2 May 2018, a 93 percent community vote in April 2019, audits delivered September 2019, "accepted" on 21 February 2020, EIP-2538's opposition on 25 February, then stagnant; the share claim in the EIP's own text: "as much as 40 percent of the Ethereum network may now be secured by ASICs" (undated inside a 2018 to 2020 document; no year-by-year series exists). After the Merge: Classic's hashrate went 64 to 183 TH/s in one day; today Classic reads 129.9 TH/s and ETHW 2.15; at USD 0.10 per kWh every Ethash chip in the table loses money (E9 Pro minus USD 5.28 a day), and a later wave (iPollo V1 3.6 GH/s at 3,100 W, June 2022; Jasminer X16-P 5.8 GH/s at 1,900 W, August 2023) holds Classic (https://hashrateindex.com/blog/how-much-ethereum-mining-hashrate-can-other-blockchains-absorb/ ; https://2miners.com/etc-network-hashrate ; read 8 October 2026). + +**The mapping to v6.** Ethash is class C in full, and its chips are the f = 1 chip of `chip-model-v3.md` section 5 at three points on the packaging ladder: commodity DRAM on a board (E3, E9: 1x to 4x), memory sized and placed per chip (Linzhi: 2x), DRAM bonded to the logic (Jasminer: 5x, the model's HBM3 row). None of v6's four layers touches a chip of this class: the program, the mixer, the op mix, the family schedule and the acceptance floor are all firmware or configuration to a controller that stores the dataset; the only layer that reaches it is layer 2, and only when the dataset passes the chip's board, which at 2 GiB plus 0.5 GiB a year is year 60 for a 32 GB board (section 4.2). Does v6 close it: **no**. The number: 5.1x per joule on GDDR7 and 7.5x on one HBM3 stack at zero premium against the 5090 unlocked, 3.6x at the 5090's 1,300 MHz knee, 2.1x at the knee with the class v4 shadow at k = 1 (`counter-asic-4-research.md` section 0); the history's measured band for exactly this chip class is 1.0x (E3) to 5.1x (Jasminer), and Jasminer's number is the model's HBM-class row reached in 2021 on a 40 nm logic die. The forward line of the same mechanism is lane B's (`docs/analysis/class-v6/hardware-future.md`, master 34f63b3c, section 4.4 and its table row for fine-grained hybrid-bonded DRAM on logic: 13x to 17x per joule at zero shadow, modelled, on the 2028 to 2030 roadmaps); the Jasminer X4 is that row's shipped precedent, five years early and at 5x on a planar node, which is the reason to read lane B's 13x to 17x as a ceiling a first product will not reach and a second one will approach. The one thing Igneum has that Ethash did not: the honest card is latency-bound at 4-byte reads, not bandwidth-bound at 128, so the chip's energy per read is the activate's 909 pJ plus a 32-byte atom (2.0 nJ on GDDR7 against the card's measured 8.7 to 10.9 nJ marginal), which is where the 5.1x comes from, and the shadow is the only term on the card's side of that ratio. + +### 2.3 RandomX (Monero, 30 November 2019): the chips, RandomX v2, and the X9's withdrawal + +**The mechanism of the hash.** A VM running 8 chained programs of 256 instructions, 2,048 iterations each, over a 2 MiB scratchpad in three tiers (16 KiB, 256 KiB, 2 MiB) and a 2,080 MiB dataset derived from a 256 MiB cache by SuperscalarHash, a random superscalar program of about 450 instructions with 155 64-bit multiplies per function, tuned to a 170-cycle latency to match DRAM; double-precision floating point in all four rounding modes; the light-mode chip (cache on die) pays 760 cycles and 1,240 multiplies per item, "energy comparable to loading 64 bytes from DRAM" (https://github.com/tevador/RandomX/blob/master/doc/design.md and doc/specs.md, read 8 October 2026).

Work per hash rises 52.9 percent; measured CPU hash rates move from minus 12.9 percent (a 100 W-capped 9950X) to plus 8 percent (a 28 W laptop part) (https://github.com/tevador/RandomX/blob/master/doc/design_v2.md and /pull/317, read 8 October 2026). The press reading: v2 "doesn't seem to be an attempt to eliminate every form of specialization", it removes "unintended advantages that benefited hardware in version 1.0" (https://www.coinpro.ch/en/?p=42081, 31 March 2026). + +**The timeline.** Live 30 November 2019; X5 at parity hardware 46 months later (September 2023), on chips SChernykh believes mined privately from about 2021 (21 months after launch); the X9 announced at 73 months and withdrawn at 78; v2 released at 76 months with a 52.9 percent work increase and no activation date; the R1X undelivered at 82 months. The X9's withdrawal is read by the trade press as Bitmain waiting for v2 rather than shipping a part the fork would hit (https://oneminers.com/blogs/news/antminer-x9-cancelled-what-bitmain-pulling-the-model-means-for-monero-mining, 31 July 2026). Corrections to the 5 October file's row 17: the X9 was not delivered in July 2026 (withdrawn, zero units), and "no fork as of October 2026" is now "v2 released, activation pending". + +**The mapping to v6.** RandomX is class D (the firmware-survivable machine): every X5 claim is a many-core RISC-V board over commodity DRAM, a better CPU for a fixed VM spec, and the v2 fixes are exactly the parameters class v6 layer 1 draws (program length, the op mix's cost on the honest machine, the memory latency slack). Two readings bind: first, RandomX's whole gap is the CPU's out-of-order overhead against an in-order many-core board, and Igneum's honest machine is already the in-order many-lane design, so the X5's 1.46x has no Igneum analogue; the Igneum analogue of "a better machine for the fixed spec" is class C's memory chip at 5.1x. Second, the v2 changes show what a per-era draw of program length and op mix buys: it closes the slack a faster honest core leaves (the latency-shadow argument of class v4 in RandomX's words), and it costs the honest machine up to 12.9 percent of rate at the power-capped point, which is the Igneum premium question in another chain's numbers. Does v6 close it: yes for the class (layers 1 and 3 draw what v2 had to fork to change), and the number is the X5's 1.46x, which becomes the shadow's premium arithmetic on Igneum (2.1x at k = 1 at the knee). + +**The Qubic episode (2025) as the detector's lesson.** Qubic's pool reached an average of 22.09 percent of Monero's hashrate over the campaign and 23 to 34 percent during ten withholding periods, with six-hour windows near 50 percent and never a daily 51 percent (Lee and Kim, arXiv 2512.01437, AFT 2026, read 8 October 2026); an 18-block reorg on 14 September 2025 invalidated 117 to 118 transactions. Detection rested on things the adversary controlled: one payout wallet, extra-nonce signatures in its coinbase, its own pool API; when Qubic encrypted its job messages and rotated keys those signals went, and Rucknium's warning stands that a miner split across addresses and solo-mining leaves only the orphan rate and double spends as signals. Qubic ran stock CPU miners, so the nonce-distribution method that found the 2018 and 2019 chips (MoneroCrusher: nonces clustered under about 1.34 billion of 4.3; 85.2 percent of the hashrate, about 5,400 machines at 128 kH/s) did not apply. For Igneum's detector (the 5 October addition 4) this means two instruments, not one: the per-program rate spread and nonce pattern for a chip, and a share-by-key-and-template pattern for a concentrated honest fleet; neither survives an adversary who randomises both. + +### 2.2 ProgPoW (EIP-1057, May 2018): the independent review, the exploit, and the adopters + +**The mechanism.** A random program re-drawn every PROGPOW_PERIOD (50 blocks in 0.9.2, 10 blocks, about 2 minutes, in 0.9.3) from the block number, so miners compile ahead; 16 lanes, a 32-register file per lane, 64 outer iterations each with 4 uint32 DAG loads per lane (256 bytes per lane-group read), 11 cache accesses into a 16 KB cache and 18 random math ops drawn from eleven (add, mul, mulhi, min, rotl, rotr, and, or, xor, clz, popcount) with KISS99 as the generator and FNV1a for merging; keccak-f800 with 32-bit words at both ends "to reduce impact on total power"; the stated aim is that "the algorithm's requirements match what is available on commodity GPUs", the stated chip gain "minimal, roughly 1.1 to 1.2x", with the remaining chip levers named as removing the graphics pipeline, the floating-point units and minor merge-function tweaks (https://eips.ethereum.org/EIPS/eip-1057 and https://github.com/ifdefelse/ProgPOW, read 8 October 2026). + +**The independent review, exactly.** Least Authority (report version 9 September 2019): no issues, five suggestions. Suggestion 2, the light-evaluation attack, in the report's words: "on-die scratchpad memory of around 100 MB is possible in ASICs, that we can fetch at least 128 bytes during a single read, and that such a read might have a latency in the range of one to some tens of cycles"; a chip replaces every DAG read with calc_dataset_item(cache, i) over an on-die cache, at a latency near DATASET_PARENTS x k1, "as low as about 300 cycles"; "the energy expended per bit to access DRAM is about 3 pJ per bit, but when the memory access is on-chip, it decreases to 0.3 pJ per bit, which is a 10x improvement"; conclusion: "efficient light-evaluation attacks may become possible within a few years. This is also an issue that applies to Ethash"; the mitigation offered: raise DATASET_PARENTS from 256 to 512 (which 0.9.4 did), and "for details on the related hardware advancements, please see Bob Rao's corresponding audit report". Suggestion 5: "hardware targeting machine learning is also useful for ProgPoW mining" (the PDF at https://leastauthority.com/static/publications/LeastAuthority-ProgPow-Algorithm-Final-Audit-Report.pdf, text extracted, read 8 October 2026). Bob Rao (6 September 2019): "the only meaningful metric is Energy per Hash"; Ethash chips "about 1.6x hashrate per watt over GPUs"; "10/7 nm processes provide up to 25 Mbits per mm^2 of SRAM and 100 M transistors per mm^2"; "with sufficient on-chip memory available, ProgPOW ASICs with << 0.1x E/H over GPUs can be built"; three chip approaches costed (the whole DAG on die, "possible in 2025+"; a custom stacked memory; the cache only, "about 51 MB as of 30 August 2019", with the item recomputed, "512 MB SRAM" on the slide); the DAG-on-die economics on a three-year Moore cadence: a single die holding a 6.49 GB DAG in 2024 to 2025 at 532 mm^2 and USD 221 per good die (USD 34 per GB), or sixteen dies of 33 mm^2 at USD 6.51 each; "a die that can hold the logic and entire DAG at any point in time becomes cost effective at around 2025 and beyond"; the 16-die split "becomes cost effective today": 16 x USD 6.62 of silicon plus USD 16 of package plus USD 25 of PCB plus USD 25 of heatsink and interface, "about USD 172 total", against "about USD 240" for a GPU board with "8 GB GDDR6 about USD 150"; a 10 nm-class chip "USD 20 M+" and "1+ year to develop, can be done if there is a 150-day ROI to miners" (the PDF at https://github.com/ethcatherders/progpow-audit, text extracted, read 8 October 2026). + +**The exploit.** Kik, 4 March 2020: the 64-bit seed carried between the two keccak passes is too small; fix a seed and compute its mix once, grind an extra-nonce in the header to meet the difficulty on the final keccak, then scan nonces until keccak_progpow_64(header_hash, nonce) equals the seed; the memory path runs once per 2^64 nonces and the rest is keccak, "ASICs benefit most when network difficulty exceeds 2^50"; 0.9.4 widened the carried state from 64 to 256 bits (the digest of the first keccak plus the mix plus padding) (https://github.com/kik/progpow-exploit ; https://github.com/ifdefelse/ProgPOW ; read 8 October 2026). + +**Linzhi's claim.** 8 January 2019: "shocked" by ProgPoW with USD 4 M invested, and a stated intention "to study the feasibility, and then build, ProgPoW ASICs"; the repository recording their claim puts a ProgPoW chip at 3x to 8x (https://github.com/Souptacular/linzhi ; https://forklog.com/proizvoditel-majnerov-linzhi-vystupil-protiv-realizatsii-predlozheniya-progpow/ ; read 8 October 2026). No ProgPoW chip was ever shown. + +**The timeline and the adopters.** EIP created 2 May 2018; a 93 percent vote of 2.93 M ETH in April 2019; both audits September 2019; "accepted" on the 21 February 2020 call; EIP-2538's opposition 25 February; the 6 March 2020 call with "frustration but little progress"; stagnant since; the Merge 15 September 2022. KawPow (Ravencoin, 6 May 2020), FiroPoW (26 October 2021), ProgPowZ (Zano), Sero and Quai (January 2025) run ProgPoW variants; no chip is listed for any of them on WhatToMine or asicminervalue as of 8 October 2026 (https://whattomine.com/coins/234-rvn-kawpow/gpus ; https://www.asicminervalue.com/), on prizes that never reached the market caps at which the 2018 chips appeared (the 5 October file, section 2.5). + +**The mapping to v6.** ProgPoW is class D (a sequencer over eleven ops reads the per-period program as configuration) and class E (Kik). Its review is the one piece of the record that priced Igneum's own chips before Igneum did: the light-evaluation attack is the f = 0 recompute chip (M16, 0.92x at the op budget with the mixer at x8), and Rao's 16-die DAG holder at USD 172 is the f = 1 chip at USD 470 of memory and board. Does v6 close it: the class D half yes (layers 1 and 3 are ProgPoW's period change made an era draw, with no fork), the class E half yes (Igneum's seed is 256 bits through the VDF; layer 4 is the acceptance-side test the audits said to add), and the Rao half no (class C, section 2.1). The number: ProgPoW claimed 1.1x to 1.2x against a conventional compute chip and never priced the memory-system chip; Igneum's model gives that chip 5.1x. + +### 2.4 Cuckoo Cycle (Grin, January 2019): the GRN1, the G32, the iPollo G1 and the 2025 bounty + +**The mechanism of the hash.** Find a 42-cycle in a random bipartite graph of 2^31 or 2^32 edges from siphash; the lean solver keeps "1 bit per edge and 1 bit per node in one partition", bottlenecked by random node-bit access, which "requires tons of SRAM, which is lacking on CPUs and GPUs, but easily implemented in ASICs"; the mean solver keeps 33 bits per edge and is bandwidth-bound, about 4x faster; Tromp: "our primary PoW of Cuckatoo31+ is intended to be mined by ASICs"; the family is "a Proof of SRAM" (https://github.com/tromp/cuckoo ; https://forum.grin.mw/t/cuckatoo31-im-mutability/2442 ; read 8 October 2026). The memory geometry a chip needs (the 13 November 2018 feasibility thread): the 512 MB edge bitmap is accessed sequentially and can sit in external DRAM (96 GB/s with 128 MB on chip); the node bitmap must be SRAM; Cuckatoo31 fits one die at "256 + 64 = 320 MB of on-chip memory", Cuckatoo32 needs "at least 640 MB" or 512 MB of SRAM plus 512 MB of serial DRAM; "trimming is over 99 percent of the effort" (https://forum.grin.mw/t/cuckatoo32-feasibility/1199 ; https://forum.grin.mw/t/advice-on-cuckatoo-hardware-implementation/12042).

Cuckoo's resource was SRAM size at 320 to 640 MB per die, and a 16 nm die with 512 MiB of SRAM was designed, priced and sold before the economics killed it; the one chip that shipped sat at 3x because half its working set stayed in DRAM. Layer 2 answers it the way the chip model already does: Igneum's 256 MiB cache is the GRN1's die (128 mm^2 at N5, `sram-mirror.md`), and the 2 GiB dataset above it is what the lean solver never had to hold; the time-memory curve Cuckoo got wrong by 50x and then bounded in 2025 (linear in time, not in energy) is the curve `chip-model-v3.md` section 5 draws for Igneum (monotone; the f = 0 end pays 6.3 nJ and 9,360 ops per item against 1.2 to 2.0 nJ for a stored one), and its verdict is the same as Tromp's: memory can be traded for time, not for energy. Does v6 close it: yes, and it was closed at class v3. The number: 50x planned on C31 and 3x shipped on C32; Igneum's f = 0 chip 1.86x per joule and the f = 1 chip, which Cuckoo did not have because its memory was never a DRAM-scale random-read set, 5.1x. + +### 2.5 Equihash 200,9 (Zcash, October 2016): the Z9 and the parameter-following chip + +**The mechanism of the hash and its claim.** Wagner's generalised birthday problem with algorithm binding; the paper's claim: a PoW needing "700 MB of RAM" that "increases the computations by the factor of 1000 if memory is halved" (https://eprint.iacr.org/2015/946, read 8 October 2026). Zcash chose (200, 9), which solvers run in about 144 MB (approximate); no trade-off-resistance bound was ever proved for Equihash (Alcock and Ren, 2017, cited through the Fudan paper below). + +**The chips and the mechanism.** Bitmain's BM1740 (Z9 mini, announced 3 May 2018 at 10 kSol/s and 300 W, shipped June; Z9 September 2018, 42 kSol/s at 970 W on 48 chips) is "a single-chip Equihash miner", "presumably with around 128 MB of memory", eDRAM or SRAM "an open question" (Tromp, 7 June 2018, https://forum.z.cash/t/let-s-talk-about-asic-mining/27353/3332): the whole (200, 9) working set on one die, which the 1,000x claim had assumed impossible at that size. A (144, 5) solver needs over 1.6 GB and cannot fit; Tromp "physically inspected the product and did not find enough memory to handle (144, 5)". Vorick's architecture (13 May 2018) is the other route: "a basic architecture for equihash ASICs that would be able to successfully follow a hardfork that chose any set of parameters", with "massive speedups and efficiency gains over GPUs", because on a chip "you can merge the memory and computation together ... do most of your manipulating in-place" (the essay, through https://steemit.com/crypto/@waraa/the-state-of-cryptocurrency-mining). The published design of that route: Bai, Gao, Hu and Zhang, NDSS 2019, an adversary solver whose sort step is a linear-time insertion sorter of 2,048 "smartcell" flip-flop chains feeding merge stages buffered in off-chip DDR4 (list 1,600 Mib, pairs 2,016 Mib for (200, 9)), pair generation and XOR on small MCUs; simulated at SMIC 28 nm: 40.6 Sol/s at 500 MHz for 0.75 to 0.78 W, 52 to 54 Sol/J against about 4 for the best GPU software, "at least 10x" and parameter-independent (https://www.ndss-symposium.org/wp-content/uploads/2019/02/ndss2019_09-5_Bai_paper.pdf, read 8 October 2026). Later chips: Innosilicon A9 (June 2018, 50 kSol/s at 620 W, USD 9,999); Z11 (April 2019, 135 kSol/s at 1,418 W, 12 nm); Z15 (420 kSol/s at 1,510 W); Z15 Pro (June 2023, 840 kSol/s at 2,780 W). Against a GTX 1080 Ti at 735 to 785 Sol/s and 250 to 305 W (about 2.7 Sol/J): Z9 mini 12x, Z9 16x, A9 30x, Z11 35x, Z15 Pro 110x (https://www.asicminervalue.com/miners/bitmain/antminer-z9 ; https://www.asicminervalue.com/miners/bitmain/antminer-z15-pro ; https://en.wikibooks.org/wiki/ZCash_mining_GPU_Comparison/GPU_Mining ; read 8 October 2026). + +**The timeline.** Hash live 28 October 2016; three groups mining on secret chips before the Z9 announcement (Vorick); the Z9 mini at 18 months; the Zcash Foundation's statement of 8 May 2018 asked whether chips "could handle different parameters of Equihash" and the community vote of June 2018 went 45 to 19 against prioritising resistance; no fork; proof of stake announced November 2021; the Z15 Pro at 80 months. + +**The mapping to v6.** Class B, with a lesson for layer 1: Equihash's parameters (n, k) were the knob the forks turned (Bitcoin Gold to 144,5; Beam to 150,5; Flux to 125,4), and a chip was designed to follow "any set of parameters" by keeping the memory off die and the sort on it. A per-era draw of a parameter a chip can follow is a configuration to it; a draw of the memory SIZE is the one that forced the Z9's single die to fail on (144, 5), which is layer 2's mechanism, not layer 1's. Does v6 close it: yes by layer 2 (a 2 GiB set is not a die), and the parameter-following chip is the honest warning for layer 1's draws. The number: 12x at the first chip, 110x by 2023, against a hash whose 1,000x penalty claim never had a proof; Igneum's claim for its curve rests on a drawn curve (`chip-model-v3.md` 5.4) and the in-house pass's exact pebbling optimum (adv-cache-3), and still has no proof. + +### 2.6 Scrypt and Argon2: the Litecoin chips, the lookup gap, and MTP + +**Scrypt (Tenebrix and Litecoin, 2011; N = 1,024, r = 1, p = 1: a 128 KB scratchpad).** The mechanism of every scrypt chip is one 128 KB of on-die SRAM per hashing core and many cores per die: Watkins (2014) "there only needs to be 128 KB of memory per processor ... one core driving a 128 KB cache", SRAM chosen over every other memory as fastest, salsa20/8 about 60 percent of the runtime and memory access 38 percent (https://arxiv.org/pdf/2208.02160); the BM1485 of the L3+ (June 2017, 504 MH/s at 800 W): 12 cores per chip, "every BM1485 integrates on-die SRAM to hold that scratchpad", 28 nm, 288 chips per unit, about 1.7 MH/s per chip (so about 1.5 MB of SRAM per chip, arithmetic) (https://d-central.tech/mining-glossary/bm1485/ ; https://www.asicminervalue.com/miners/bitmain/antminer-l3-504mh); the L7 (November 2021, 9.5 GH/s at 3,425 W, USD 15,000, 0.36 W per MH against the L3+'s 1.58): the BM1489 at TSMC 7 nm, 480 chips (https://d-central.tech/mining-glossary/bm1489/ ; https://cryptoage.com/en/2550-bitmain-antminer-l7-is-a-new-asic-miner-for-litecoin-and-dogecoin.html); the Innosilicon A2 (21 April 2014, 28 nm, 1.6 to 1.8 MH/s per chip at 10 W, about 150 MH/s per box at 1 kW: https://www.design-reuse.com/news/34403/innosilicon-28nm-litecoin-asic-reference-miner.html); the KnC Titan (March 2014, 250 MH/s at 800 to 1,000 W, USD 9,995, "4 chips x 2,284 cores": https://www.coindesk.com/markets/2014/03/28/kncminer-updates-titan-spec-promises-250mhs/), whose 2,284 cores cannot each hold 128 KB on a 2014 die, so it shared scratchpads or took the time-memory trade-off (not confirmed). The trade-off itself is in the designer's record: Percival (18 November 2012) on storing every other scratchpad entry: memory halved for about 25 percent more BlockMix work, area-time about 0.625x, the trade favouring the attacker at 2x to 4x reductions, "already in the paper's cost estimates" (https://mail.tarsnap.com/scrypt/msg00092.html; all read 8 October 2026). Against an R9 280X at 700 to 740 kH/s and 340 to 450 W at the wall: A2 about 70x, L3+ about 300x, L7 about 1,300x per joule (derived, approximate). Scrypt-N (Vertcoin 2014: N doubling by timestamp up to 2^30) was dropped on 13 December 2014 for Lyra2RE "as a proactive defense against emerging Scrypt-N capable ASICs", because raising N "simply involves doing more iterations" and more SRAM or a larger lookup gap (https://vertcoinproject.org/vertcoin_whitepaper.pdf ; https://coincentral.com/what-is-vertcoin-a-beginners-guide/). + +**Argon2 as a proof of work (MTP, Zcoin, 10 December 2018).** Argon2d over 4 GB with a Merkle tree; Dinur and Nadler (2017): malicious proofs with under 1 MB, 1/3,000 of the honest memory, at a computation penalty of 170, "more than 55,000 times faster than what is claimed by the designers", with a 2^64 one-time precomputation, by injecting chosen blocks that steer Argon2d's data-dependent addresses (https://eprint.iacr.org/2017/497); MTP 1.2 patched it before launch; no Argon2 chip was ever built; Firo replaced MTP with FiroPoW on 26 October 2021 (https://firo.org/2021/10/01/firopow-and-instantsend-release.html). Yescrypt and yespower (GlobalBoost-Y 2014; Yenten, Cranepay, Tidecoin on yespower from 2018; L2-latency-bound sequential work: https://www.openwall.com/yespower/): no chip found, small prizes. + +**The mapping to v6.** Class B throughout, and the parameter-growth lesson for layer 2 in its oldest form: Scrypt-N's automatic growth was abandoned because a chip follows a scratchpad that grows by doubling the SRAM it already has, and Percival's own 2012 note says the time-memory trade favours the chip at 2x to 4x. Does v6 close it: yes by layer 2 (no die holds 2 GiB; the curve is monotone against partial stores); the lookup-gap lesson is the reason the dataset's chained cache has a drawn pebbling optimum (adv-cache-3) rather than a claim.

The matrix multiply is a warning for the reserve's mm8 family, not for the hash: a fixed 64 x 64 nibble multiply is the cheapest thing silicon does, and the measured rows agree (the 5090's int8 MAC at 1.4 to 4.1 pJ against a 5 nm array's claimed 0.04 to 0.4, `counter-asic-4-research.md` 15.1a). Does v6 close it: yes, closed since class v2 (no fixed function to unroll); the number, 720x, is what a fixed pipeline does to compute-bound work, and the reserve's ordering (section 4.3) keeps mm8 last for exactly this reason. + +### 2.11 CryptoNight (Bytecoin 2012, Monero 2014): the X3, the secret chips, and four forks + +**The mechanism of the hash.** 524,288 iterations of an AES round plus an 8-byte multiply over a 2 MB scratchpad sized to a 2014 per-core L3; latency-bound at SRAM scale. + +**The chips.** Bitmain Antminer X3, announced 15 March 2018 at 220 kH/s and 550 W (465 to 470 W measured), 180 BM1700 chips on three boards, USD 11,999 for batch 1 falling to USD 1,900; no teardown or vendor description of the BM1700 exists (node, SRAM, AES units not found). The arithmetic is the mechanism: 1.2 kH/s and about 2.6 W per chip is one or two 2 MB scratchpads in on-die SRAM with a hardware AES round per chip, and nothing else reaches that rate in that power (approximate, inference). Baikal Giant N, March 2018, 20 kH/s at 60 W. Against a Vega 64 at 2,009 H/s and about 200 W card power (about 10 H/W) the X3 is about 40x per joule; against a Threadripper 1950X at about 1,000 H/s and 185 W, about 75x (approximate) (https://www.asicminervalue.com/miners/bitmain/antminer-x3-220kh ; https://www.asicminervalue.com/miners/baikal/bk-n ; https://hothardware.com/reviews/monero-mining-with-amd-ryzen-threadripper ; read 8 October 2026). + +**The secret chips.** Monero's own 2018 review: by early 2018 "it was estimated that 80 to 90 percent of the network was specialized hardware" (https://web.getmonero.org/2019/02/12/2018-year-in-review.html); about half the hashrate (about 500 MH/s of 1,000) left at the v7 fork on 6 April 2018; Krawiec-Thayer's nonce study (24 November 2018) found half of all blocks with nonces in the lowest 0.002 percent of the space, patterns that "evaporated abruptly" at the fork (https://www.hackernoon.com/utter-noncesense-a-statistical-study-of-nonce-value-distribution-on-the-monero-blockchain-f13f673a0a0d). Vorick (13 May 2018, through secondary coverage): secret Monero ASIC mining "since early 2017, making up 50 percent of the hashrate". The timeline from the hash to the first secret chip is therefore about 33 months (April 2014 to early 2017), not the 43 the 5 October file gives (which counted to the fork); the announced chip came at 47. + +**The four forks and what each cost a chip.** v7 (6 April 2018): a one-byte tweak to the main loop; half the hashrate left; "a precaution and deterrent". v8 (18 October 2018, height 1,685,555): a whole-cache-line shuffle (4x the bandwidth demand) plus a 64:32 division and a 64-bit square root per iteration, 5 to 10 percent off CPU rate; the hashrate went from about 320 MH/s to just under 1,000 MH/s before March 2019 with chip nonce patterns visible from December: chips back inside two months, dominant inside four (https://decrypt.co/14421/ ; https://en.cryptonomist.ch/2019/05/08/mining-monero-hashrate-pow-change/). CryptoNight-R (9 March 2019, brought forward from April after the detection): a per-block random sequence of 60 to 69 integer instructions (63 on average; MUL 40 percent, XOR 23, SUB 12, ADD 12, ROR 8, ROL 6) over 9 registers, seeded by height so miners compile ahead; SChernykh's claim is a chip's minimum latency for the random math "at least 2.5 times higher" than the DIV plus SQRT it replaced (a chain of 15 multiplies against 6), with up to 1.5x more for an out-of-order chip; a hardware engineer in the PR thread estimated a chip could still do about 18 ns per iteration, comparable to a CPU (https://github.com/SChernykh/CryptonightR ; https://github.com/monero-project/monero/pull/5126). The hashrate fell from about 1 GH/s to 140 MH/s and settled at 300 to 350 MH/s; no CN-R chip is documented in its nine months. RandomX followed on 30 November 2019. + +**The mapping to v6.** CryptoNight is class B (SRAM-scale memory: layer 2 closes it, the 2 GiB dataset is 1,000 mm^2 of SRAM even at N5) and class D (the forks: v7 and v8 kept the machine's shape and the chips returned; CN-R changed what the machine had to be, a per-block random program, and no chip came in nine months, which is the per-epoch random program Igneum ships). The number: 40x per joule for the X3 against a GPU; the Igneum analogue, the f = 0 recompute chip that holds the 256 MiB cache on die, reads 0.92x at the op budget and 1.86x per joule (`chip-model-v3.md` 5.4), and CN-R's 2.5x latency claim is the fixed-shape mixer's 3x factor in the other direction. The honest residue: Monero's chips were found by nonce pattern four months after a fork at 85 percent of the hashrate; Igneum has no detector yet. + +### 2.12 X16R (Ravencoin, January 2018): a drawn order over fixed functions + +**The mechanism and the chips.** Sixteen hash functions in an order set by the previous block hash, a per-block automatic change with no fork. The sequencing changed; the sixteen primitives did not, so one large FPGA holding all sixteen cores needs only per-block routing: BittWare and SQRL's CVP-13 (Xilinx VU13P) was announced on 7 September 2018 naming "X17r, X16r and TimeTravel10" (https://www.cryptoninjas.net/2018/09/07/squirrels-research-labs-and-bittware-launching-new-fpga-crypto-mining-hardware/ ; https://www.bittware.com/cvp-13 ; read 8 October 2026). An unknown pool held 10 to 20 percent of blocks in February 2019, 30 to 40 in March, 45 by 11 July; the OW Miner OW1 (September 2019, 182 MH/s at 1,500 W, about USD 500) and SKC Turing R1 (680 MH/s at 800 W, about USD 1,500) were sold as ASICs, their insides unconfirmed; against a P102-100 at 35 MH/s and 219 W the OW1 is 0.75x and the R1 about 5x per joule (https://cryptoage.com/en/1782-asics-ow-miner-ow1-and-skc-miner-turing-r1-for-the-x16r-algorithm-exist.html ; https://miningboard.com/algorithms/X16R). X16Rv2 (1 October 2019) swapped one hash in; on 30 January 2020 Tron Black called the chips' return "evident"; KawPow followed in May 2020; Ravencoin's roadmap records "ASICs have been developed for X16R (and X16Rv2)" (https://cointelegraph.com/news/ravencoin-community-clash-over-mining-algorithm-continues ; https://github.com/RavenProject/Ravencoin/blob/master/roadmap/README.md). + +**The mapping to v6.** Class D in its purest form, and the warning for layer 1: a draw over a FIXED set is a configuration to a chip that holds the set. Igneum's op-mix draw is over twelve families a chip holds from genesis; what the draw does cost a chip is nothing, and what it costs the honest card is the per-vendor energy table. Does v6 close it: the fixed-function lane is closed by the per-epoch program (there is no sixteen-core pipeline to route), and the draw itself is a governance device. The number: 5x for the one X16R box with a plausible chip inside; the GPU-without-graphics sequencer's gain on Igneum's program side is bounded by that kind of figure, and its memory side by class C's 5.1x. + +### 2.13 Lyra2REv2 (Vertcoin, August 2015): FPGA first, then the Zig Z1 + +A memory-hard sponge (Lyra2 at T = 1, R = 8, C = 256, p = 1: a matrix small enough for on-die SRAM per core, on the order of 200 KB, approximate) inside a chain of hashes. The FPGA came first: an academic Lyra2 core on 16 July 2018 and a full FPGA miner at 2.6 to 3.7 MH/s and 323 to 432 nJ per hash, "significantly more energy efficient than both a GPU and a commercially available FPGA-based miner", which confirms commercial bitstreams before the chip (https://arxiv.org/abs/1905.08792); the Dayun Zig Z1 on 19 September 2018: 6.8 GH/s at 1,200 W, 28 nm, USD 8,000, "equivalent to 100 GeForce GTX 1080 Ti", about 20x per joule against a 1080 Ti at about 68 MH/s and 250 W (https://cryptoage.com/en/1231-first-asic-miner-lyra2rev2-dayun-zig-z1.html; read 8 October 2026). Vertcoin 0.14.0 forked at block 1,080,000 (1 February 2019) "to rid the network of the current generation of Lyra2REv2 ASICs and FPGAs" with Lyra2REv3 (R = 32, p = 4: 16x the memory), then Verthash in January 2021 (https://github.com/vertcoin-project/vertcoin-core/releases/tag/0.14.0). The 22 reorgs of October to December 2018 and the December 2019 attack came through rented hash on a hashrate the forks had reset (the 5 October file, row 7). Mapping: class B (layer 2 closes it) and lesson 5 (the fork reset the hashrate to a rentable size, which v6's layers 1 and 3 never do).

Blake3: double Blake3, chosen as chip-friendly; the Goldshell AL-BOX (May 2024, 360 GH/s at 180 W), Antminer AL1 (15.6 TH/s at 3,510 W) and AL1 Pro (August 2024, 16.6 TH/s at 3,730 W), AL3 (8 TH/s at 3,200 W); about 100x to 220x per joule against an RTX 4090 at 6.0 GH/s and about 300 W (https://www.asicminervalue.com/miners/goldshell/al-box ; https://whattomine.com/asics/294-bitmain-antminer-al1-pro). Blake2s on Kadena: the Goldshell KD5 (March 2021, 18 TH/s at 2,250 W) and Antminer KA3 (166 TH/s at 3,154 W) against a GTX 1660 Super at 633 MH/s and 79 W: about 1,000x and 6,500x (https://www.asicminervalue.com/miners/goldshell/kd5 ; https://miningboard.com/algorithms/Blake%20%282s-Kadena%29). NexaPow (SHA-256 plus a secp256k1 Schnorr signature per nonce, "useful ASICs"): the DragonBall A21 (December 2024, 3.4 GH/s at 1,800 W, USD 6,999) is only about 2.2x per joule against an RTX 4090 at 320 MH/s and 380 W, because big-integer elliptic-curve arithmetic leaves a fixed pipeline little to strip (https://spec.nexa.org/mining/NexaPOW/ ; https://www.asicminervalue.com/miners/dragonball-miner/a21 ; all read 8 October 2026). Mapping: class A, closed since class v2; the numbers (100x to 6,500x) are what a fixed function costs, and NexaPow's 2.2x is the one compute-bound row where the chip's edge stayed small, because the work was already a wide multiplier chain, which is the shape of the ALU shadow's k band (0.3 to 0.8) in another chain's numbers. + +## 3. The three lessons, with the evidence + +**Lesson 1. The chip that stores the dataset is firmware-immune to every draw; only joules and memory growth move it.** Evidence: the five Ethash chips (section 2.1) never touched Ethash's compute and never needed to; Rao's audit said in 2019 that "the energy expended to move data from DRAM to compute are the same for GPU or ASIC" and that the only lever a chip has is the memory's own energy per bit, which Jasminer took by bonding the DRAM to the die; the Least Authority audit's conclusion that "the random math core likely prohibits the build of a light-evaluation based ASIC" was about the f = 0 chip and said nothing about the f = 1 chip, which is the one that shipped on Ethash in three forms. On Igneum's side the identity of `counter-asic-4-research.md` section 2 says it in one line: at zero premium the edge is E_card over E_mem and no hash change touches it. What v6 inherits: 5.1x per joule on GDDR7 at zero premium against the 5090 unlocked, 3.6x at its 1,300 MHz knee, 2.1x with the class v4 shadow at k = 1, and USD 2.8 against 14.7 per MH/s. What binds on v6: every per-era draw of layer 1 and every family epoch of layer 3 must be priced against this chip as a configuration change (a recompile per epoch, a new mapping per era) and never claimed as a cost to it; the public text's "under 2x" stays worded against the recompute chip, as the 6 October verdict already requires. + +**Lesson 2. Automatic change beats the human fork only where it costs the chip a redesign, and the one parameter that does is the memory.** Evidence: Grin's three Cuckaroo tweaks (17 July 2019, 15 January 2020, 16 July 2020) each changed the edge function and no chip ever shipped for the lane, but each was a hard fork with a new solver and the lane was scheduled to die; Monero's v7 and v8 kept the machine's shape and the chips were back inside four months, CN-R changed the machine and no chip came in nine months, RandomX changed it again and the X5 took 46 months; X16R's per-block order cost the FPGA nothing; Scrypt-N's public, slow growth was abandoned before a chip because the chip could be sized for years of it; Ethash's DAG growth is the one automatic rule in the record that killed a shipped chip, and it killed the one chip whose memory was sized to the card fleet's own limit (4 GB), 20 to 27 months after shipping. The compile and design cycles bound the race: Bitmain built the A3 in about 5 months and Halong the B52 in 9 (Vorick), a full Vivado compile on a mid-size part runs 42 to 160 minutes and hours on a large one (PRflow, FPT 2019), so an hourly program outruns every compile and a six-monthly change outruns no chip. What binds on v6: layers 1 and 3 close the governance failure (no fork, no hashrate reset to a rentable size, which cost Vertcoin two 51 percent attacks) and tax a sequencer chip die area, not architecture: Rao's own figure is about 1 M gates and 0.025 mm^2 at 10 nm for ProgPoW's whole inner loop, so a lane array carrying every reserve family is the class v4 shadow core's 30 mm^2 of N5 and USD 25 to 40, not a wall. Layer 2 is the one real lever, and its value is its floor and ceiling, not its tracking: the floor keeps class B closed (2 GiB is 1,000 mm^2 of SRAM at N5), and a ceiling under the honest tiers' memory is a requirement, because any rate that ages out a 32 GB chip board retires the 8 GB card first. + +**Lesson 3. A steered or biased address pattern is always found after launch unless the test lives in the acceptance rule, and every new draw needs its own null.** Evidence: Kik's exploit came five months after two audits that named the seed's keccak as a thing to scrutinise and three days after the EIP was declared dead; Dinur and Nadler found MTP's under-1 MB proof before launch only because the construction was published and reviewed, and the fix was a construction change; AP-F8-1 was found by the attack-pass lane one day after class v4 reached the devnet, in 96.6 percent of the class's programs, and took three sub-versions and class v5's floor to close; the in-house pass then found a program that passed every part of the rule and still read a live hot set, which is why the floor sits at 0.995 and not 0.98. What binds on v6: layer 4's test is a per-site ratio against the window model, and the window model is a function of the dataset size, the windows, the era stride and the read width, so a draw of any of those changes the null and the census must be re-derived per era (2.2 s per candidate at 2^20 on one box core; 0.7 percent of candidates refused at the floor); the residue the floor cannot reach without refusing most clean programs (the shadow-written concentrations at 0.9992 to 0.9997, about 1.0004x) moves with any draw of the shadow placement and needs its own ceiling per era, with the F8 gate's 1.2x-of-window shape. + +## 4. The four layers against the history, layer by layer + +### 4.1 Layer 1: per-era draws of the class parameters + +What is declared: the parameters now fixed by release (the mixer round count within the tested margin, the op-mix weights within the measured safe band, the read width, the program length, the shadow placement) are drawn per era from chain state like the program. What the history says about each: + +| Parameter drawn | The precedent | What the draw costs a chip | What it costs the honest card and the verifier | Reading | +|---|---|---|---|---| +| Mixer round count (within the tested margin) | RandomX made the item derivation itself a random program so a chip could not hard-wire it (SuperscalarHash); CryptoNight-R's random math raised chip latency 2.5x | nothing on the f = 1 chip (it derives no item); on the f = 0 recompute chip the fixed shape is the 3x factor, and a drawn ROUND COUNT keeps the shape: the chip builds the widest count and gates the rest | the verifier's 10 ms gate caps the count (x8 is 2.1 ms per warp on the reference core, x16 about 3.7); the daily build 23 to 77 ms at x8 | a draw of the count within a margin the chip already covers is firmware; the lever against the recompute chip is a drawn SHAPE (the 5 October addition 2, reserve), and the recompute chip is not the one anyone builds (chip-model-v3 5.6) | +| Op-mix weights (within the measured safe band) | X16R drew the ORDER of sixteen fixed hashes per block and an FPGA served it at 1.3x within 20 months; ProgPoW drew the math per period and no chip exists on its adopters in eight years, on small prizes | a sequencer chip over the twelve families covers any weight table; the measured GPU cost per family is the real constraint (shfl 55.8 pJ against add 11.3 on the 5090: a shuffle-heavy draw taxes the card up to 5x per instruction with no better k) | the per-program hash-rate spread must stay under the 5 percent rule on every vendor across the band (the six-era spread was 1.3 to 3.2 percent on the era layout) | right as a governance device (no fork), neutral as a chip device; the band must be bounded by the per-vendor cost table of `counter-asic-4-research.md` 15.1a, not only by the rate spread | +| Read width | w16 moved the honest denominator 2.7 percent and the chip's cost not at all; w64 made the 5090 bandwidth-bound (71.9 MH/s); the 9070 XT pays a 64-byte line at every width | the chip pays the same 32-byte atom at w4 and w16; wider reads hand a custom controller the Ren-Devadas bandwidth lever (the Ethash chips' whole edge) | a 47 percent loss on the 5090 at w64 | the one parameter whose draw can move the memory physics the wrong way: keep the allowed set at {1} (as 1.13.1 already does) unless a wider width is measured latency-bound on all three vendors; a draw over {4 B, 16 B} is harmless and worthless | +| Program length | ProgPoW's loop count and Ethash's 64 accesses were fixed; RandomX's 8 chained programs of 256 instructions fixed; no chain drew its program length | a longer program is more shadow work per hash: the class v4 lever (the latency ladder) priced at 2.1x at k = 1; a chip builds the longest rung's core and idles it on short eras | the verifier rung 3 is inadmissible on the reference core (latency-ladder section 5); the card's premium per op 6.2 to 11.3 pJ measured | the draw must stay inside the admissible rungs (0 to 2); its value is the governance one (the ladder stepped by draw instead of by 90 percent signal), and the honest card pays the premium on every era | +| Shadow placement | no precedent in any chain; the per-load placement (16 blocks of 16 after every load) was DEAD as drawn on 7 October (acceptance in execution order accepts 1.4 percent of candidates; `counter-asic-4-research.md` 20.2a-close) | the per-load form would force the chip's ALU core inside every read's dependency (the USD 200 M break-even row, 16.2) if a sound form existed | compile-ahead at 16 sites; a class change | draw only over placements shown sound (today: the one block after the loads); the per-load form is the research item, not a draw value | + +### 4.2 Layer 2: the dataset's size tracking chain-state growth with a floor + +What is declared: the state-derived dataset's size tracks chain-state growth, with a floor, so fixed-memory silicon ages out. The history has exactly two scheduled memory-growth rules that ran against shipped hardware, and one of them killed a chip: + +| Precedent | The rule | What it did to chips | What it did to honest cards | Source | +|---|---|---|---|---| +| Ethash DAG growth | +8 MB per epoch of 30,000 blocks (about 0.7 GB a year; Rao's audit, slide "DAG size"); 1 GB at launch (July 2015), 3.0 GB by July 2019, 3.94 GB by November 2020 | the Antminer E3 (shipped July 2018, 4 GB of DDR3) ran out of DAG room on Classic at epoch 328 (about 3.56 GB, March 2020) and on Ethereum at about block 11.4 million (about October 2020) after a 30 March 2020 firmware stretched its DDR use: 20 to 27 months after shipping, 57 to 63 months after the hash went live; the A10 Pro (6 GB) and every later chip carried more memory than any card of its year and never aged out | the same rule retired 3 GB cards in 2018 and 4 GB cards by December 2020; Ethereum Classic cut the DAG to 2.47 GB (Thanos, ECIP-1099, block 11,700,000, 28 November 2020) to keep the 4 GB cards after the August 2020 51 percent attacks, and its own text says the fork kept "competitive mining across both GPU and ASIC hardware" | https://ethereumclassic.org/blog/2020-11-27-thanos-hard-fork-upgrade/ ; https://coingeek.com/memory-limitations-prompt-bitmain-antminer-e3-to-halt-etc-support/ ; https://cointelegraph.com/news/bitmains-antminer-e3-to-continue-mining-ether-with-new-update (all read 8 October 2026); Rao's audit, the DAG-size slide (https://github.com/ethcatherders/progpow-audit) | +| Autolykos v2 table growth | N = 2^26 elements of 31 bytes (2.08 GB) until block 614,400; then about 5 percent every 51,200 blocks (N doubles every 102,400 blocks, about 142 days at Ergo's 2-minute block) to a cap of 2,143,944,600 elements at block 4,198,400 (about 66 GB) | no chip has shipped for Autolykos as of today, on a small prize; the rule has never been tested against one | the table passes 8 GB in about 2 years of growth and 16 GB a year later (arithmetic on the rule); Ergo's GPU fleet thins by card memory on a schedule it chose | https://docs.ergoplatform.com/mining/autolykos/ (read 8 October 2026) | + +The arithmetic that binds. A chip's memory is bought by the board, and today's prices are the chip model's: GDDR7 about USD 20 per 2 GB device, so 32 GB on a 512-bit board is USD 320; one HBM3 stack 24 GB about USD 200 (`chip-model-v3.md` 5.1, September to October 2026 prices). Igneum's schedule as specified (2 GiB plus 0.5 GiB a year, doubling steps at years 4, 12, 28; spec 1.13.3) reaches 4 GiB at year 4 and 8 GiB at year 12. Against that schedule: + +| Memory the chip or card holds | Years until the dataset passes it | Who it is | +|---|---|---| +| 8 GB | 12 | the honest 8 GB card (the first tier out, `card-lifetime-2026-10-05.md`) | +| 12 GB | 20 | the honest 12 GB card | +| 16 GB | 28 | the 9070 XT class | +| 24 GB | 44 | one HBM3 stack; the 4090 and the M5 Max class | +| 32 GB | 60 | the f = 1 GDDR7 chip's board; the 5090 | + +So layer 2 as a rate "tracking chain state" ages out fixed-memory silicon only if the dataset grows faster than a chip generation's memory headroom, and every rate that does that retires the honest small cards first by the same table. The E3 is the only case in the record where a growth rule beat a chip, and it beat a chip that had under-provisioned memory by a factor the card fleet also hit (4 GB). The rule that would hurt the f = 1 chip is one that keeps the dataset above what one board of commodity DRAM holds at the chip's price point, and that rule is unaffordable for the honest fleet. The honest reading: layer 2 is the right lever class (the memory is the one parameter a stored-dataset chip cannot read as firmware), and its value is set by the floor and the ceiling, not by the tracking: a floor keeps the dataset above every SRAM die (class B stays closed: 2 GiB is 1,000 mm^2 of SRAM even at N5), and a ceiling keeps it under the honest tiers' memory. Between those two lines the chip's board holds whatever the card holds, and the growth rate changes nothing for it. What "tracking chain state" adds over the fixed schedule is governance (no release decides the size) and the class v5 link (the dataset is built from the state, so the size follows the state's record count naturally); it is not an anti-chip rate. Resolved by the synthesis lane (11:2x UK, `docs/design/class-v6-rotating-family.md` section 7b on `counter-asic-4`): layer 2's rule carries a per-year ceiling as its first constant, the fixed schedule's power-of-two step for that year, so the chain's state can bring a step forward and never add one; "retires cards before chips" is recorded as the reason the ceiling exists. Under that rule the table above is the ceiling's own schedule, and the honest 8 GB tier's year-12 line stands whatever the state does. What this file adds for the record: if the chain's state grew the way Ethereum's did (approximate, from memory: the account and storage state passed 100 GB in its eighth year), a dataset tracking it with no ceiling would have outgrown every consumer card inside the first decade; the ceiling is what makes layer 2 a governance rule and not a fleet-retirement rule. + +### 4.2a One schedule, priced (main's ask of 11:2x UK, for the 20:00 reading) + +Main asked for one dataset-floor schedule priced per tier and against the chips, so the 20:00 reading carries a decision: 6 GiB at the v6 epoch, 10 GiB two years on, 14 GiB at four years, each step by height like a class epoch, the schedule a consensus field. The method is `card-lifetime-2026-10-05.md`'s: a card's room for the dataset is its usable memory (75 percent of card memory, the standing rule "the whole working set under 6 GB on an 8 GB card"; 50 percent of Apple unified memory) less the non-dataset working set (best: 32 KiB scratch, the cache freed after the build, 254 to 479 MiB by tier; worst: 128 KiB scratch, the cache resident, 600 to 1,500 MiB). The population is the bench table's measured cards (`site/miner-bench.json`, 8 October 2026: 32 distinct consumer cards, one Apple part, eight datacentre parts); the fleet's own card census is not a file this lane could find and is owed, so the shares below are by count of distinct measured cards, not by hashrate. + +**What the memory arithmetic says about main's three steps.** A step fits a tier when the dataset plus the working set is under the tier's usable memory. + +| Step | 8 GB (usable 6,144 MiB) | 10 GB (7,680) | 11 GB (8,448) | 12 GB (9,216) | 16 GB (12,288) | Apple 16 GB unified (8,192) | 24 GB (18,432) | 32 GB (24,576) | +|---|---|---|---|---|---|---|---|---| +| 6 GiB (6,144 MiB) | **does not fit the rule**: 6,398 best, 6,744 worst, 78 to 82 percent of the card; fits only if the budget rule moves to about 85 percent (a headless rig with no display) | fits (6,404 best, 63 percent) | fits | fits | fits | fits (6,432 MiB, 79 percent of its usable half) | fits | fits | +| 10 GiB (10,240 MiB) | out | out | out | **out**: 10,506 best, 10,888 worst, 86 to 89 percent | fits (10,518, 64 percent) | out | fits | fits | +| 14 GiB (14,336 MiB) | out | out | out | out | **out**: 14,614 best, 15,032 worst, 89 to 92 percent | out | fits (14,752, 60 percent) | fits | + +So main's schedule as stated retires, under the standing budget rule: at 6 GiB the 6 GB tier and, unless the rule is loosened to about 85 percent, the 8 GB tier (22 percent of the measured consumer cards: the RTX 3070, 3070 Ti, 3060 Ti, 4060, 4060 Ti 8 GB, 5060, 2070 Super) on day one; at 10 GiB the 10, 11 and 12 GB tiers and Apple 16 GB (another 31 percent: the RTX 3080, 1080 Ti, 2080 Ti, 4070, 4070 Ti, 4070 Super, 5070, 3080 Ti, 3060, Arc B580) at year 2; at 14 GiB the 16 GB tier (28 percent: the RTX 5060 Ti, 5070 Ti, 5080, 4080, 4080 Super, 4070 Ti Super, 4060 Ti 16 GB, RX 9070 XT, RTX A4000) at year 4, leaving 24 GB and above (16 percent of the measured consumer cards, plus every datacentre part). That is not the tier order main's note describes, so the schedule that drops the tiers in that order is priced beside it: + +| Step | Dataset | Year | Who falls off (share of the 32 measured consumer cards) | Who holds, and at what share of card memory (best / worst) | +|---|---|---|---|---| +| v6 epoch | 5.5 GiB (5,632 MiB) | 0 | the 6 GB tier (RTX 2060: 3 percent) | 8 GB at 72 / 76 percent (the worst case one point over the rule); 10 GB 77 percent; Apple 16 GB unified at 72 percent; everything larger | +| +2 years | 8 GiB (8,192 MiB) | 2 | the 8 GB tier (22 percent), the 10 GB RTX 3080 (3 percent: 8,452 of 7,680), Apple 16 GB unified (8,480 of 8,192) | 11 GB at 100 percent of usable (the 1080 Ti and 2080 Ti: out in practice, 6 percent); 12 GB at 69 / 72 percent; 16 GB; 24 GB; 32 GB; Apple 32 GB at 52 percent of its usable half | +| +4 years | 11 GiB (11,264 MiB) | 4 | the 12 GB tier (22 percent) | 16 GB at 70 / 73 percent; 24 GB at 48 percent; 32 GB; Apple 32 GB at 71 percent of its usable half | +| the fixed schedule's own steps beyond | 16 GiB | the year the state brings it forward, else year 28 | the 16 GB tier (28 percent); Apple 32 GB | 24 GB at 68 percent; 32 GB | + +Reading, per tier, in the form main asked for (the year each falls off, and the share of today's measured cards that is): on the priced schedule the 6 GB tier falls at the v6 epoch (3 percent), the 8 GB tier and the 10 GB RTX 3080 and the Apple 16 GB laptop at year 2 (25 percent of the consumer cards plus the base Apple laptop), the 11 GB Pascal and Turing parts in practice at year 2 (6 percent), the 12 GB tier at year 4 (22 percent), the 16 GB tier at the 16 GiB step (28 percent), and 24 GB and above hold through every step priced. On main's schedule as stated the same tiers fall two years earlier each, and the 8 GB tier falls on day one unless the 75 percent rule moves. Either way this is the fleet-retirement rule the ceiling exists to bound (section 4.2): a step every two years retires a quarter of today's measured consumer cards each time. + +**Against the chips, with the number.** Three chips, by what the step does to each: + +| Chip | What a step costs it | The number | +|---|---|---| +| The hybrid-bonded DRAM chip sized at launch (the Jasminer X4's shape: DRAM dies bonded to the logic at tapeout, 5 GB per unit in 2021; the E3's shape in commodity form, 4 GB of DDR3 soldered to the board) | its memory is fixed at tapeout, so it dies at the first step it cannot carry, as the E3 did 20 to 27 months after shipping. On main's schedule a chip sized to the 6 GiB floor with 8 GB of bonded DRAM dies at the 10 GiB step (year 2); on the priced schedule a chip sized to 5.5 GiB with 8 GB dies at the 8 GiB step (year 2); a chip sized with 16 GB holds through year 4 on both and dies at the 16 GiB step. But the schedule is a consensus field read at genesis, so a maker sizes to the step it wants to survive: the X4's 5 GB was Ethash's DAG plus a year, chosen off a public schedule; the E3 died because its memory was sized to the CARD FLEET's limit, not to the schedule | kills only the chip that under-sizes; sizing to 16 GB costs the X4 shape about 3x its 2021 memory die area (approximate) and the E3 shape USD 160 more of GDDR7 (8 x USD 20, chip-model-v3 5.1) on a USD 470 part | +| The f = 1 GDDR7 chip on a board (the record's class C; 16 x 2 GB devices, 32 GB) | nothing until the dataset passes 32 GB: every step priced here fits its board; a bigger step buys more devices at USD 20 per 2 GB | USD 0 per step through 16 GiB; its 5.1x per joule and USD 2.8 per MH/s stand at every step | +| The SRAM store (the f = 0 recompute chip holding the cache on die) | the dataset's size costs it nothing (it derives every item); the CACHE's doubling under option C costs it capex only: 128 mm^2 and USD 46 per good die at 256 MiB, 255 mm^2 and USD 111 at 512 MiB (year 4 on the fixed schedule, or the year the state brings the doubling forward), 510 mm^2 and USD 306 at 1 GiB; and the mirror's size is what forces it onto a 7 nm or better node (the 5 October file, section 2.5) | USD 46 to 111 per die at the year-4 doubling; its edge stays 0.92x at the op budget and 1.86x per joule (`chip-model-v3.md` 5.4), unmoved by the dataset's steps | + +The honest sentence for the 20:00 reading: the dataset-floor schedule is a fleet-retirement rule with a chip tax of USD 0 to 160 per unit on the chips that matter (classes C and B), and it kills only a chip whose maker ignores a public consensus field; the one precedent of a growth rule killing a chip (the E3) is a precedent of a maker sizing to the fleet, not to the schedule. If the schedule is adopted, the 75 percent budget rule and the 6 GiB floor cannot both stand for the 8 GB tier; 5.5 GiB keeps the 8 GB card inside the rule in the best case and one point over in the worst, and the headless-rig reading (about 85 percent) is what makes 6 GiB fit. The fleet's hashrate-weighted census is owed before the share column is read as a hashrate share. + +### 4.3 Layer 3: scheduled family epochs by height, every 180 days, no release + +What is declared: a new instruction family goes live on a height schedule, every 180 days by default, with no release (the reserve of spec 1.13.2, ordered at genesis).

A full Vivado compile on a mid-size Xilinx part (ZCU102) runs 42 minutes typical and 160 worst (PRflow, FPT 2019, https://ic.ese.upenn.edu/abstracts/prflow_fpt2019.html) and "several hours" on a large device (a 2021 Paderborn talk); the Least Authority audit called a 2-minute period "impractical" for a bitstream; the one KawPow FPGA on record is an academic VU35P build at 5.6 MH/s (NTU 2022, https://tdr.lib.ntu.edu.tw/handle/123456789/84103?locale=en), under an eighth of a 2022 GPU. So an hourly program outruns every compile and every design cycle; a 180-day family epoch outruns no chip's design cycle and does not need to, because the family is in the generator from genesis. + +Reading. Scheduled change beat chips in exactly one shape: Grin's, where each change was a new function nobody could know in advance, and even then only because the lane was built to die. Every change a chip could read at genesis (X16R's order, ProgPoW's period, Igneum's reserve) became firmware. Layer 3 as declared is X16R's and ProgPoW's shape, automated and spaced at 180 days: it removes the fork (lesson 5 of the 5 October file, and the one thing that cost Vertcoin two 51 percent attacks), and it taxes a sequencer chip die area for families not yet live. The honest number for that tax is small: the reserve's candidates are integer ALU operations (shifts, bit-field extract, andn, byte permute, popcount, select, the second shuffle form; mm8 last), each a few thousand gates per lane; against the f = 1 chip's USD 470 of memory and board, a lane array carrying every reserve family is the same 30 mm^2 of N5 the class v4 shadow already forces (`counter-asic-4-research.md` 16.1: USD 25 to 40 of die). The one family that is not cheap for a chip to carry idle is one whose unit is large (mm8's tile engine), and that is exactly the family the measured rows say not to use for forcing (the 5090's int8 MAC at 1.4 to 4.1 pJ against a 5 nm array's claimed 0.04 to 0.4: `counter-asic-4-research.md` 15.1a). So layer 3 is right for governance and neutral for the chip; what would make a family epoch cost a chip a redesign is a family whose semantics are not knowable at genesis, which is the random item-derivation program of the 5 October addition 2 (a per-day SuperscalarHash-style derivation), the one RandomX idea Igneum has not taken, and it acts on the f = 0 chip only. + +### 4.4 Layer 4: the (c''') floor and the F8-form uniformity test per era draw + +What is declared: the (c''') acceptance floor (the per-site distinct-index ratio at or above 0.995 against the window model, spec 1.4.7.2) and the F8-form uniformity test generalised to each era's parameter draw, with a redraw on failure. The history has three attacks of this one class, and in every case the test that would have caught it lived outside the acceptance rule: + +| Attack | The steer | Found when | What the fix was | Source | +|---|---|---|---|---| +| Kik's ProgPoW exploit (4 March 2020) | the 64-bit seed between the two keccak passes: fix a seed, compute its mix once, then grind nonces until keccak_progpow_64(header, nonce) equals the seed; the memory path is run once per 2^64 nonces, so a chip that never touches the DAG wins once the difficulty passes 2^50 | after two tentative approvals and five months after both audits (September 2019) | ProgPoW 0.9.4 widened the carried state from 64 to 256 bits (the digest of the first keccak, plus the mix, plus padding) | https://github.com/kik/progpow-exploit and https://github.com/ifdefelse/ProgPOW (read 8 October 2026) | +| Dinur and Nadler on MTP (2017) | the prover controls the memory's contents, so by injecting blocks it steers Argon2d's data-dependent addresses into a set it can hold in under 1 MB at a 170x compute penalty, in place of 2 GB | before launch, by cryptanalysis, not by the design's own test | MTP 1.2 patched the construction | the 5 October file [P18] [S38] | +| AP-F8-1 on class v4 (7 October 2026) | a load site whose source register was last written by a lossy op (or, mul, mulhi) saturates to all-ones or zero at a known rate, and the era map sends the constant to one item; 96.6 percent of class v4 programs carried a lossy-sourced load; the worst seed read 29x the window model on one item | in the attack-pass lane's census, one day after the class shipped to the devnet | sub-versions 1 to 3 (the freshness fixpoint, the executed shadow block, the (c'') ratio at 0.98), then class v5's (c''') at 0.995 | `docs/plans/counter-asic-3-status.md` section 7c; spec 1.4.7.2 | + +Reading. Layer 4 is the right answer to this class and the only one of the four layers that acts on a mechanism the record shows beating hashes after launch. Two things bind on it. First, the test can only see what its null models: (c''') measures distinct-index ratios against the window model, which is a function of the dataset size, the per-site windows, the era stride and the read width; a draw of the read width or the program length changes the null, so "generalised to each era's draw" means the window model is re-derived per era and the census re-run per draw, not one floor reused. The cost is known: 2.2 s per candidate at 2^20 on one box core, once per epoch draw on a node, and 0.7 percent of candidates refused by the floor (spec 1.4.7.2). Second, the residue the floor cannot reach without refusing most clean programs is the shadow-block-written concentrations at 0.9992 to 0.9997, worth about 1.0004x to a chip (spec 1.4.7.2), and a per-era draw of the shadow placement moves that residue, so the redraw rule needs its own ceiling stated (the 1.2x-of-window gate of F8 is the right shape; the number per era is the census's to set). The Kik lesson is separate and already closed: Igneum's seed is 256 bits through the VDF and the program is the epoch's, so there is no 64-bit state to grind; the header-locality search (the 5 October check 1) remains the nearest analogue and was measured by adv-accept-2 in the in-house pass. + +## 5.

The founder's word of 11:1x UK: class v6 is declared with four layers as its spine (per-era draws of the released parameters; the state-derived dataset's size tracking chain state with a floor; scheduled family epochs every 180 days with no release; the acceptance floor and the F8-form uniformity test generalised to each era's draw), and deep research opens: "see if anything can be optimised, added or invented". This file is the invention lane's answer: every candidate layer beyond the four as one paragraph, one known-failed test stated as a harness run, and one chip-model row, then the ranked list of what v6 should add. The synthesis is the research lane's `docs/design/class-v6-rotating-family.md` (branch `counter-asic-4`), which reads this file. + +Status: a research document and a gate plan. No consensus code this week; nothing here touches the devnet, the testnet object, the spec or any served page. Every number carries a label: **measured** (a run on a named box or card, the log named), **modelled** (arithmetic on the chip model's cited figures, `docs/analysis/chip-model-v3.md` section 5), **claimed** (a vendor's or an author's figure, URL and date), **approximate** (from memory or a scaling). The rule every candidate is held to: **reject what costs GPUs more than it costs chips, and say so with the number; keep what raises a chip's k or capex or shortens its useful life more than it raises every GPU tier's cost.** + +## 0. One page + +The frame is last night's identity (`docs/analysis/counter-asic-4-research.md` section 2): against the chip anyone builds, a GPU's memory system without the GPU (chip-model-v3 section 5.5, the `f = 1` chip), the per-joule edge is `(E_card + F) / (E_mem + k F)`, with `F` the premium per hash the card pays for forced work and `k` the chip core's energy per forced op over the card's. Zero premium is zero forcing. No hash-side design reaches a chip edge of about 2x at zero premium; the premium-free floor is the card's own whole-card energy over the chip's memory energy, 3.6x on a 5090 at its knee (measured card, modelled chip), and the class v4 shadow buys 2.1x at `k = 1` for 82 to 90 W on a 5090. The four layers of v6 render a fixed-function chip useless on its release day and move nothing in the identity for the GPU-like chip. So an invented layer can do one of four things, and only four: raise `k` (nothing on measured rows reads `k` above 1, section 15.1a of the research file); raise the chip's capex or project cost (the one lever the identity does not see); shorten the chip's useful life (layers 1 and 3 already do this for fixed silicon); or cost the honest cards less at the same `F`.

randomised memory topology (a chip's address decoder permutes its lines for nothing; the stride and interleave are already drawn); the VRAM-size ratchet as a lever (a chip buys 24 to 32 GB that the 8, 12 and 16 GB tiers cannot: it retires cards first);

the devnet pays nothing); the 5090 tier's one number is that the per-load placement costs it LESS than class v4's whole block at the same work (13 to 14 W measured on the 16 x 27 form, the 256 x 1 form's row due about 12:45 UK); the 5070 Ti has no measured row in this lane (the 4070's rows are the proxy, approximate); the Apple tier's open question is the inline footprint of a 4,096-line block per iteration (the 1,024-line block cost the M5 Max 17 percent on 6 October, measured), which decides whether rank 1 needs a block-shape cap for Apple; a pool user sees nothing; a node verifies the per-load forms in the same 8.3 to 8.8 ms as class v4 (measured); a chip maker sees its project forced onto one advanced die by rank 1 and its interposer escape closed by rank 2. + +## 1.

The 16 x 27 form (16 sub-blocks of 16, each iterated 27 times) was built on 7 October and closed the same night: 27 passes of a 16-instruction map right before a load collapses or biases the load's address register before any base instruction can re-randomise it, and the acceptance rule in execution order refused it. The sound form named there and never drawn is one pass of a long segment per load: 16 sub-blocks of 432 instructions, each run once, the same 6,912 instructions per iteration. The experimental class caps the per-load block at 4,096 instructions, so today's census takes the two forms inside the cap that bracket it: `mx8+shl4096x1` (16 x 256, one pass, 59 percent of class v4's work per hash) and `mx8+shl2304x3` (16 x 144, three passes, class v4's exact count), and the constant-work ladder between them (16 x 256 x 1, 32 x 128 x 2 ... 16 x 16 x 16) that reads how the acceptance rate depends on the sub-block length against the pass count. The 432 x 1 form itself needs the cap raised, a one-line change in a research-only parser, which this lane does not make this week; its number is bracketed by the 256 x 1 and 144 x 3 rows and the ladder's flatness between them. + +Known-failed test, as a harness run: `ERA=none SEEDS=256 /srv/builds/v6-invention-census.sh` on build-1 under `lease pool 48`. Fail: a form whose per-candidate rejection is 0.98 or above (P(exhaust) at the 256-attempt cap above 0.5 percent, an epoch without a program every few months). The 16 x 27 form reads 0.989 and fails (section 3.1). Pass: a form under 0.95 (P(exhaust) under 2 x 10^-6). The 256 x 1 form reads 0.927 and passes; so does every form with a sub-block of 36 instructions or longer (0.927 to 0.949). The second known-failed case is the instrument's own: `ERA=era` on the same seeds reads 0 of 256 accepted on every per-load form, with the window's fixed top bits named as biased index bits (section 3.3); the fixed instrument (bits at or above `28 - k_off_s` excluded from the value-level test) must accept per-load forms under drawn eras at the no-era rate within the binomial band, and still refuse the per-load record of 7 October (candidate 0 of the first export, 1,482 duplicate lanes). + +Chip row: + +| Column | Value | Label | +|---|---|---| +| A fixed-function chip's `k` | unchanged (the work is the same ALU mix); its capex: the controller cannot be a 28 nm part with the core elsewhere, so the project moves from USD 5 M (no core) or 30 M (a core on its own die) to about 60 M (one N5-class die or a 2.5D package); break-even cap about USD 200 M in years 1 to 2 (s = 0.30) against about 100 M | modelled (16.2, the mission lane's N3 single-die row; a GDDR7 PHY on N5 is unpriced) | +| A GPU-like chip's per-joule edge | unchanged: 2.1x at `k = 1`, 3.5x at `k = 0.3` at the knee; its capex per MH/s 3.0 to 4.3 USD against 2.8 | modelled | +| RTX 5090 | the 16 x 27 v2 export: 135.90 MH/s at 448.3 W unlocked against the whole block's 137.51 at 462.2 (the premium 137 against 151 W, -14 W); at the 1,300 lock 126.04 at 282.9 against 126.93 at 295.8 (-13 W); the 256 x 1 and 144 x 3 forms in today's PC 1 job (the hash lane, after the AMD grid, about 12:45 UK) | measured (research file 20.3); the sound forms' rows owed | +| RTX 5070 Ti | no row (no card in this lane); the 4070's class v4 premium at its tune point, 30 W for no rate, less the block effect, is the proxy | approximate | +| Apple M5 Max | the 16 x 27 v2 export 26.88 MH/s against 27.01 (-0.5 percent, Metal packbench, 7 October); the 256 x 1 form's inline text is 4,096 shadow lines per iteration where the 1,024-line block cost the M5 Max 17 percent (6 October, measured), so its footprint is the open Apple number: OWED (a Mac measurement under the measure lock, which this lane does not run; the hash lane's or the shipper's Metal row) | measured for 16 x 27; the sound form's row owed | +| The verifier | 8.28 to 8.55 ms cold with the sibling loaded (256 x 1), 8.44 to 8.82 (144 x 3), against class v4's 8.33 to 8.63 on the same core in the same minutes; the acceptance's dynamic test 35 ms per candidate (1,111 ms for 32), 13.7 candidates per seed on average: about 0.5 s of one core per epoch | measured (section 3.2) | +| The acceptance | 0.927 per candidate (256 x 1), P(256 consecutive rejections) 0.927^256 about 4 x 10^-9 per seed; class v4 sub-version 3 reads 0.681 and 2 x 10^-43; the gap is the missing dataflow rule (the per-load class is not the class v4 shape, so (a'), (c') and (c'') do not run on it; the value-level bias test catches the same population: 1,563 of 2,329 bias rejections name index bit 0 at a one-count near 4,096 or 12,288 of 16,384, the product's low-bit law) | measured (section 3.1) | + +Verdict: KEEP as layer 5, the first thing v6 adds beyond the four, because it is the only mechanism found that moves the project cost, it costs the 5090 less than class v4's own block (measured on the 16 x 27 form; the sound form's row today), and its acceptance is now a measured 0.927 with a named fix (the sub-version 3 dataflow fixpoint run over the real execution order, base and sub-blocks interleaved, as the generator's draw rule) that the research file's 20.2 already asked for. What it does not do: move the energy identity by one joule. The founder's "useless as soon as it dropped" is layer 1's and 3's sentence; layer 5's sentence is "the chip that can be built costs twice as much to start". + +### 2.2 Layer 6: the register-file width drawn per era, the link tax on layer 5 (KEEP, rank 2) + +The hash runs on 8 registers per lane, a prototype value to be fixed at gate 1 (spec 1.4). The lane state a chip must carry is those 8 words plus the nonce and counter, 64 B, which is why the chip's 1,172 lanes are 73 KB of SRAM and why, under layer 5, the per-read crossing is 128 B at 17.5 G reads per second, 2.2 TB/s: an interposer carries that (a one-stack HBM package moves about 0.8 to 1.2 TB/s of memory traffic and a die-to-die link of a few TB/s is a 2.5D product; approximate, from memory), so the chip has an escape at USD 200 of package instead of one die. Draw the register count per era from {8, 16, 32} (the acceptance rule's part (b) over every register; the program length scaled so that every register is written, or registers above 8 initialised and read by the shadow alone) and the crossing is 128 to 256 B per lane per read: 4.5 to 9 TB/s, past the interposer class, so the single die is forced and the project's USD 60 M row has no cheaper branch. A GPU pays nothing in rate while latency-bound: a CUDA lane holds up to 255 registers, the 5090's 7,262 lanes in flight at 256 B are 1.9 MB against about 43 MB of register file (170 SMs x 256 KB; approximate), and occupancy at 32 live registers plus the kernel's temporaries fits the 64K-register SM at full residency (approximate, unmeasured). The verifier's register-major arrays grow 4x (4 KB per warp) and the interpreter's cost per op does not move. + +Known-failed test, as a harness run: the generator with `REGISTERS` as a class field (a research-only change behind a pack name, `mx8+r32`), then `v6inv-census.sh` over the per-load forms at 8, 16 and 32 registers. Fail: the 32-register form's per-candidate rejection above the 8-register form's by more than the binomial band (more registers, more cold registers, more (b) rejections unless the program length scales). Pass: rejection at or under the 8-register form's; the F8 census at 2^24 on 64 seeds within 1.2x of the window model (the top 0.1 percent of items); the cold verify on core 40 with core 88 loaded under 10 ms. Then the card: one pack per register count on the 5090, rate within 1 percent of the 8-register pack at both states (the occupancy claim measured, not argued). + +Chip row: + +| Column | Value | Label | +|---|---|---| +| A fixed-function chip | with layer 5: the lane state per read 128 to 256 B, 4.5 to 9 TB/s of die-to-die traffic at the 5090's read rate; the interposer branch (USD 200 of package) closed, the single N5-class die forced; the project about USD 60 M either way, but with no cheaper escape; alone (without layer 5): nothing, the state crosses once per iteration | modelled, the link figures approximate | +| A GPU-like chip's per-joule edge | unchanged; its lane SRAM 73 KB to 300 KB (nothing) | modelled | +| RTX 5090 / 5070 Ti / M5 Max | 0 rate while latency-bound (approximate: the occupancy arithmetic above; a measurement is the pack); watts: the same `F` (the same ops) | approximate until the pack runs | +| The verifier | 4x the register arrays per warp (4 KB); cost per op unchanged (0.1 ns per lane-instruction, the shadow's law) | modelled | +| The acceptance | part (b) over 16 or 32 registers needs the base program to write every register: at 64 instructions over 32 registers about 13 percent of registers are never written (approximate, e^(-64 x 0.75 / 32)), so either the base length scales with the register count (the verifier's 10 ms gate holds to about 330,000 ops) or the extra registers belong to the shadow alone and part (b) reads the base's 8 | modelled; the census decides | + +Verdict: KEEP as layer 6, conditional on layer 5 (alone it moves nothing). Its value is one sentence in the chip's project plan: no interposer saves the second die. + +### 2.3 Layer 7: warp-uniform data-dependent block selection (KEEP, rank 3, small) + +A program whose control flow depends on the data it reads is the brief's first candidate. Per-lane branches are dead on arrival: a divergent branch costs a GPU warp both paths and a chip with per-lane sequencers nothing (the history's "placed nowhere" table; RandomX's one predictable branch targets speculative CPUs, which Igneum does not have). The form that survives is warp-uniform: at the end of each iteration a value reduced across the 32 lanes by shuffles (xor-fold of `r0`, say, which costs 5 shuffles) selects which of B drawn sub-blocks runs next, the same block for every lane of the warp, so the GPU takes one uniform indirect branch per iteration (as `sel` already takes one per iteration for the immediates) and the FPGA overlay or the fixed pipeline must hold all B blocks and pay B times the shadow's area for one block's throughput. For the GPU-like chip, a sequencer that already runs the hour's program, it is one more jump. What it buys: the per-epoch bitstream (the FPGA lane, history addition 5) holds B blocks instead of one, so a mid-size part's compile (42 to 160 minutes, PRflow, claimed in spec 1.13.1) carries B times the logic; at B = 4 a part that fitted one block does not fit, and at B = 8 the overlay must time-multiplex. Nothing in the energy identity moves. The acceptance must run every reachable path (B blocks per iteration, each judged by (a') in its own order) and the uniformity census must read the selection's bias (a selection that favours one block is a block that runs more). + +Known-failed test, as a harness run: a research-only class `mx8+sh256x27+sel` (the generator draws B blocks, the interpreter selects per iteration from the warp-folded `r0`), then `igneum-pow accept` over 256 seeds with every path judged, and `attack-f8 warps` at 2^24 on 64 seeds. Fail: the block-selection histogram over the 2^24 nonces outside 6 sigma of uniform (a plant: select from lane 0's `r0` bit 0 alone, which the fold is meant to prevent), or any path's (a') verdict differing from the whole-program verdict.

It is the only candidate that moves the FPGA lane, which the history ranks as the first adversary of a per-hour program (Lyra2REv2, X16R) and which no measured row in the repo has priced (the HBM FPGA row is 0.30x to 0.39x of a 5090 per watt, chip-model-v3 5.3, the soft-overlay case unmeasured). + +### 2.4 The reserve ordered by hardware orthogonality (KEEP as an ordering rule inside layer 3) + +Layer 3 unlocks reserve families by height and rotates after exhaustion. The order is Open in spec 1.13.2 except R1. The history's addition 6 said: families that force a full 32-bit datapath per lane first, the int8 tile last. Today's measured rows (research file 15.1a; the research lane's layer 3 table) sharpen it: a shuffle crossbar is the one block where the GPU's cost per op is highest (29 to 56 pJ) and a chip's is near it (about 20 pJ, approximate), so `shfla` (lane plus delta, a second crossbar form) is the family a 12-op chip lacks most and gains least on; byte permute and popcount next (small adders a chip adds for 0.1 pJ, but a datapath without them loses 4 points of the mix); the int8 tile last (k 0.03 to 0.3: a chip's MAC array is cheaper than the GPU's tensor core, so the tile is kept for datapath diversity and never for joules). The chip row is layer 3's: about USD 4 of N5 pre-wires all eight. Cost to the cards at 4 points: under 1 percent of ALU time on every vendor (measured step costs: shfla 1.91x on Apple, 1.53x NVIDIA, 0.75 to 0.84 AMD). Known-failed test: the layer 3 gate's own (a kernel built without the live family refused at packcheck; the fast-time harness crossing one family epoch with a stale miner, 0 accepted blocks after it). Verdict: not a new layer; an ordering rule, stated so the synthesis fixes it at genesis. + +### 2.5 Data-dependent program graphs, per-lane (REJECT) + +The brief's form: the program's control flow drawn from the data it reads, per lane. A GPU warp executes a divergent branch as both paths with lanes masked, so a branch taken by half the lanes doubles the ALU work of that span; a chip with a sequencer per lane pays the taken path only. Number: a shadow of 55,296 instructions per hash with one two-way branch per 64 instructions at 50 percent divergence costs the card up to 2x the shadow's premium (165 W instead of 83 at the knee on the 5090, modelled on the measured 6.4 pJ per op) for a chip cost of 1x; `k` on the branched work falls to 0.15 to 0.4. Costs GPUs more than chips. The warp-uniform form (2.3) is what survives. + +### 2.6 Latency-bound reads tied to the shard proof (REJECT) + +The hash's reads sampled from the state the miner is proving: class v5 already keys every item to a leaf of the execution state at the epoch's cut and refreshes per epoch (spec 1.8.6; proof of following). Tying the reads to the segment being proved means a refresh per block (every second) from the touched leaves. The research file's row 7 priced the refresh as a cost: a 1 GiB rebuild is 157 G ops, 13.4 ms on a 5090 and 32 ms on a 4090 (measured), 0.16 to 0.5 J on a chip core (1 to 3 pJ per op, approximate); per block that is 0.3 to 1 W against 78 W of chip hashing (0.4 to 1.3 percent) and 1.3 to 3.2 percent of a GPU's hash time (the rebuild stalls the hash on the card; the chip's rebuild runs on its core beside the memory). A delta refresh (only the touched leaves, a few KB) costs both sides nothing. Either way the GPU pays more or equal. What the tie would buy is liveness (a chip must follow the chain per block, not per epoch), which class v5's per-epoch refresh already gives at the WAN line of 2a.2. Number: GPU 1.3 to 3.2 percent of rate against a chip's 0.4 to 1.3 percent of energy. Rejected. + +### 2.7 Randomised memory topology per era (REJECT) + +The dataset's address map and stride family drawn per era: class v3 draws the stride multiplier `M`, the rotation `R` and the interleave `pos` per era already (spec 1.13.1, Counter ASIC 2.0 layers 4 and 8, decided IN at a six-era hash-rate spread of 1.3 percent on the 5090, 3.2 on the 9070 XT, 0.8 on the M5 Max, measured). The plan said then what still holds: a chip whose address decoder can permute its address lines pays nothing. Drawing a richer family (a per-era permutation polynomial over bank and row bits, a drawn item size, a drawn line interleave across devices) costs the chip's decoder a few hundred gates and costs the honest card whatever the mapping does to its own DRAM's bank parallelism: a mapping that concentrates consecutive dependent reads into one bank group hurts the side with fewer lanes in flight, which is the chip (1,172 against 7,262), but the chip adds lanes at 64 B each (lane state is free, chip-model-v3 5.5), so the asymmetry closes at no cost. The one topology lever that would have moved the chip, the hot region above the window model, was read by adv-cache-2 as the diffuse era-stride excess (a product's low bits placed at address bit `R`; 8 of 27 drawn-era programs over 1.2x), which is a FAULT the next class's value-level test removes, not a lever to keep. Number: 0 to the chip, 0 to 3.2 percent to the cards. Rejected; the existing draws stand. + +### 2.8 VRAM-size ratchet (REJECT as a lever; layer 2's floor stands) + +A floor that rises with chain state by rule is layer 2. The ratchet form (the floor tracking the modal miner's VRAM minus the prover footprint, or rising on a calendar faster than the schedule) was read against the card-lifetime table (`docs/analysis/card-lifetime-2026-10-05.md`, option (b) steps): the 4 GB tier ends at the 4 GiB step, 8 GB at 8 GiB, 12 and 16 GB at the 16 GiB step; a chip holds 24 GB (one HBM3 stack, about USD 200, modelled) or 32 GB (the 5090's own 16 devices, USD 320), so every step retires a card tier before it touches the chip, and at 32 GiB and beyond the chip adds devices and its activate-bound rate RISES with the bank count (chip-model-v3 5.7, row "dataset size": "not a lever against this chip"). Number: at the 16 GiB step the 8, 12 and 16 GB tiers are out (3 of 6 card tiers) and the chip's energy per hash moves 0. Rejected as a lever; layer 2's rule (the schedule as the floor, the state above it, a ceiling at the next cache doubling) is kept exactly as the synthesis writes it, with its honest line that it retires cards before chips. + +### 2.9 Proof-carrying hashes sampled by the pool (REJECT) + +A fraction of hashes carries a verifiable execution witness. Three witness forms were read. (i) The hash's own 128 item values: the stored-dataset chip has every item; the recompute chip derives them; cost 0 to both, 512 B per share on the wire. (ii) A Merkle witness of the state leaves under the window's root: the chip's node has it (one node serves a farm, class-v5 2a.2); cost 0 to both. (iii) A witness that the item was DERIVED (a transcript of the 8 dependent cache reads and the mixer's 72 applications): a stored-dataset chip cannot produce it without the cache and the mixer core, so this form forces the `f = 0` chip's silicon (the 256 MiB SRAM mirror, USD 46 of die and an N5 project) onto the `f = 1` chip for the sampled fraction `g`; but the honest GPU must produce the same transcript, and deriving an item on the card is 8 dependent 64-byte cache reads at the mixer's 9,360 ops (the inline kernel measured 4.8x slower than the honest kernel on the M5 Max, spec 1.8.5), so at `g = 1/128` (one item per hash) the card pays about 4 percent of its rate and at `g = 1/16` about 30 percent; the chip derives on an SRAM-resident cache at 6.3 nJ per item (modelled) for 7 percent of its energy at `g = 1/16`. Number: GPU 4 to 30 percent of rate against the chip's 1 to 7 percent of energy. Rejected on form (iii); forms (i) and (ii) force nothing. + +### 2.10 Prover-gated eligibility (REJECT) + +The block's eligibility tied to the miner's proving (a key must have proved its share of segments in the last window to claim a block), so a chip farm must carry provers. The bound is the gas bound the research file's section 7 found: the chain needs 2 shards per block at the v1 budget, about 1.6 kW of 5090 proving network-wide at 1 block per second (measured prover rows), independent of the hash rate. Against the hash: at 1 GH/s the hash draws 2.4 kW (2.4 microjoules per hash, measured), so proving is 67 percent of it; at 100 GH/s 0.7 percent; at 10 TH/s 0.007 percent. A chip farm at share `s` must prove share `s` of 1.6 kW: six 5090s per farm at any scale, which is the node it already runs. Redundant proving (each segment proved by `m` provers) raises the forcing `m` times and is the useful-work gaming the history records (Aleo, Boundless). Number: at mainnet scale the forcing is under 0.01 percent of the chip's energy; the honest card already proves. Rejected; the 80/20 split stands. + +### 2.11 Time-locked parameter commitments (REJECT beyond the era VDF) + +An era's parameters committed under a VDF so a chip cannot be built ahead: the era VDF of 7 October (`docs/analysis/era-vdf-2026-10-07.md`) already makes the era draw's input unknowable for 517 s on the fastest prover measured (chiavdf's GMP path, 208,800 squarings per second, against the production T of 108 million) and the era lead is 2 hours (`pow_era_lead`), so a chip taped out against era `n` knows era `n + 1`'s draw 2 hours before it runs, against a 5-month (Bitmain) to 13-month (a startup) design cycle (the history's lesson 5, Vorick). Lengthening the delay or the commitment changes nothing a chip can use: the GPU-like chip holds the whole drawn band as firmware (the synthesis's section 7), and the fixed-function chip is dead at the first draw outside its wired value whether it learns the draw 2 hours or 2 days ahead. The one party for whom 2 hours matters is the FPGA fleet (a bitstream compiles in 42 to 160 minutes on a mid-size part, claimed), and layer 7 (2.3) and the epoch length (spec 1.13.1, the 600 s floor) are the levers for it, not the lock. Cost of a longer lock: one honest node core for the VDF's hour per era (today) rising linearly with T; the 2019-class verify gate already missed by 2.2x (26 ms against 10, measured, proxy). Number: 0 to the chip at any delay above 2 hours; the honest node's core-hours rise with T. Rejected. + +### 2.12 A fraction of reads derived from the cache in the hash (REJECT) + +The brief's spirit of "tie the hash to what the chip must hold": a fraction `g` of the 128 reads per hash derived on the fly from the 256 MiB cache (8 dependent cache reads and 72 mixer applications) instead of read from the dataset, so the stored-dataset chip must carry the recompute chip's cache and core for that fraction. This is 2.9 form (iii) without the witness and the same arithmetic: the card's derived read is 8 dependent DRAM reads (the cache does not fit L2 at 256 MiB, and the cache doubling keeps it so), so at `g = 1/16` the card's dependent-read count per hash rises from 128 to 184 and its rate falls about 30 percent (modelled on the latency-bound rule; the inline kernel's 4.8x at `g = 1` is the measured anchor); the chip with the cache on die derives at 6.3 nJ per item (4.0 nJ of SRAM reads, 2.3 of mixer; modelled) for 0.466 to 0.50 microjoules per hash (+7 percent) and buys the USD 46 mirror and the N5 project it already needs for the shadow core. Number: GPU -30 percent of rate at `g = 1/16`, chip +7 percent of energy and +USD 46 of die. Rejected. + +### 2.13 Row-straddling and double-activation reads (REJECT) + +The chip and the card share the DRAM's physics (the research file's section 5: the same tRC, the same activate window, the same 32-byte atom). A read that opens two rows (an item straddling a row boundary, or two independent 32-byte sectors per read) costs the chip's memory +0.9 nJ per read (a second 909 pJ activation; modelled) and the card +1 sector of traffic, which at 128 reads per hash is the w64 regime (64 B per read): the 5090 fell to 71.9 MH/s, bandwidth-bound, 47 percent of its rate (measured, read-width). Number: chip +45 percent of `E_mem` (0.466 to 0.58), card -47 percent of rate and about +9 percent of energy per hash on the memory side alone.

The remaining 0.93 is not the placement: the `(c)` lane-constant and distinct rejections fall to 1 to 7 per form (they were 406 to 545 on the 16-instruction forms), and the bias rejections are the product's low-bit law at the load's source, which under class v4 the sub-version 3 dataflow rule (a') removes at the draw and which the per-load class, not being the class v4 shape, never applies. The value-level reading of the 256 x 1 form's 2,329 bias rejections: index bit 0 in 1,563 (one-counts clustered at 3,584 to 4,608 of 16,384, the 1/4 law, 680 of them; and at 11,776 to 12,288, the 3/4 complement, 212), bits 26 and 27 in 502 (one-counts 7,168 to 7,680: a mild low bias of the top address bits just outside the 6-sigma band of 384, the high bits of small products through `mulhi`, unattributed), the other 26 bits 264 in all; by site, site 0 takes 788 of 2,329 (its source is written last by the previous iteration's sub-block 15 and by the base instructions before instruction 1, where the draw's redraw covers the sub-block's last writer of the next load's source and not a product rotated into place by a later `rotl`). The named fix is one rule, the research file's own ask of 20.2: the sub-version 3 freshness fixpoint and the shared-operand rule run over the real execution order (base instruction, the load, its sub-block, the next base instructions), and a load whose source is not fresh at that point refused at the draw, which class v4 pays at 0.568 of candidates and which should bring the per-load forms from 0.93 toward 0.68. + +The acceptance's own cost: 35 ms per per-load candidate on one box core (1,111 ms for 32 candidates; the control's v2/v3 rule 2.8 ms), so an epoch's draw at 13.7 candidates is about 0.5 s of one core; the (c'') ratio at 2^20 would add class v4's 2.8 s per chosen candidate. + +### 3.2 The verifier (core 40 of the EPYC 9454P at nice 19, core 88 its SMT sibling held busy by a 100,000-warp class v4 bench for the whole run, killed by its pid at the end; the ladder's method; `igneum-pow bench --seed igneum-genesis --day 2026-10-03 --class --warps 50`) + +| Form | Cold, sibling loaded, warp base 0 / 4,096 / 1,000,000 (ms) | Avg of 50, loaded (ms) | Cold, core alone, earlier in the same minutes (ms) | Label | +|---|---|---|---|---| +| `mx8+sh256x27` (class v4's shape) | 8.63 / 8.33 / 8.33 | 8.29 | 5.90 / 6.34 / 5.24 | measured; the ladder's run 2 read 8.77 / 5.14 at load 25 on 6 October | +| `mx8+shl4096x1` | 8.55 / 8.28 / 8.28 | 8.24 | 5.44 / 5.21 / 5.17 | measured | +| `mx8+shl2304x3` | 8.82 / 8.54 / 8.44 | 8.43 | 5.31 / 5.13 / 5.09 | measured | +| `mx8+shl4096x2` | not run loaded | | 5.97 / 5.33 / 5.29 | measured, alone only | + +The per-load forms verify in class v4's time within the run's noise (the same instruction count, the same items derived, 4,096 per warp on every row).

Of the 256 x 1 form's 7,862 bias rejections, 5,536 name index bit 26 or 27 "set in 0 of 16,384" or "set in 16,384 of 16,384" at a load site, which is the era's working-set window (spec 1.13.1: `k_off = below(3)` per site puts the site on the whole dataset, a half or a quarter by fixing the top `k` bits of the index to the drawn offset `o`); the prototype's `BiasedIndexBit` test loops bits 0 to 27 and does not exclude bits at or above `28 - k_off_s`, so under any era it refuses every program with a half- or quarter-window site, which is nearly every program. The research file's 20.2a-close ("the 16 x 27 per-load class accepts 22 of 1,621 candidates over 64 seeds, 1.4 percent; 42 of 64 seeds exhaust the chain's 32 attempts") was read across drawn eras and therefore measured the instrument on most of its rows; the no-era census above is the construction's own figure (the 16 x 27 form 0.989 per candidate, 76 of 256 seeds accepted, which still fails the test of 2.1 and keeps that form dead).

Where the time goes and what closes it: a verification is two 256-bit exponentiations, about 770 group operations at 28 µs each; the operation is NUDUPL on the fixed-width integer, whose cost is the extended gcd (Lehmer rounds on 8-limb numbers) and the reduction. Three rounds of this lane moved it from 345 µs (a Lehmer convention defect that fell back to plain division every round) to 28 µs (the convention, i64 word division, 34 limbs, the x86-64 128-by-64 division); the next 2.2x is chiavdf's Pulmark reducer (reduce only when `a` exceeds 8 limbs, O-4.6) and a limb-level NUDUPL that keeps the partial gcd's intermediates in words, or GMP through `rug` behind a feature on the x86-64 Linux and Windows builds (chiavdf's 208 K/s is 6x this evaluator, which would put the verification near 4 ms as the prototype measured), with the fixed-width path the fallback for wasm and macOS.

That is the finding, and it is negative for the scheme's purpose (section 5.3): a shadow lever moves the chip's edge only by the joules it makes the HONEST card spend on work the chip cannot do more cheaply. The tensor path is so efficient on the GPU that the block adds 0.23 microjoules at most, so at `k = 1` the chip's edge falls from 6.9x to 4.9x on GDDR7 against this 4090, where the ALU shadow took the 5090 from 5.6x to 2.1x, and the tensor block costs the verifier 26x more per unit of chip-forcing energy (4.39 ms scalar per 0.23 microjoules against 0.17 ms per 0.6 microjoules).
