# Igneum evidence: every public claim, with its status

3 October 2026. One row per claim the homepage (`site/index.html`) and the litepaper (`site/litepaper.html`) make. Every number here is copied from `docs/bench-log.md`, which names the machine, the date and the command; nothing is restated from memory. Where a bench-log figure is approximate, this table says so.

## The five labels

| Label | Meaning |
|---|---|
| designed | A decision in the design document or the specification. No code carries it, or the code is a stub |
| implemented | Code exists in this repository with test vectors, and the vectors pass. Not run as a measurement of the claim |
| tested by the team | The claim was measured or exercised by the project's own people and agents on a named machine, and the result is in the bench log |
| reproduced externally | Somebody outside the project ran the published command on their own hardware and got the published result |
| reviewed independently | Somebody outside the project, paid or not, read the code or the rule and published their finding |

Three rules for reading the table:

1. Nothing on this chain has been reproduced externally or reviewed independently. Every row's last column says "none yet". The repository is private until January 2027 (`site/journey.json`), so the first two labels are the ceiling today.
2. A status applies to the exact version in the row. An audit of one version never covers a newer one; when the version changes, the status falls back to "tested by the team" until the new version is reproduced or reviewed again.
3. "Tested by the team" on one machine is one machine. The rows say which. Discrete AMD, Intel and a 2019-class CPU core have not run anything.

Versions in the table: `igneum-pow` is the Rust crate at `igneum-pow/Cargo.toml` version 0.1.0. "Repo" commits are this repository's. "Fork" commits are `vendor/igneum-node` and its worktrees (`-r3`, `-diff`, `-exec`, `-harness`), which are not in this repository's history; the row names the fork commit by its message as the bench log does. The spec is `docs/spec/` version 0.1.

## The table

| # | Claim | Where it is made | Status | Version or commit | Reproducible test | Result, date, machine | Independent verification |
|---|---|---|---|---|---|---|---|
| 1 | A new mining program every hour, compiled by the miner, with no human in the loop | Homepage hero and "This hour's mining program"; litepaper Mining | tested by the team | igneum-pow 0.1.0; repo `9812466`; fork "PoW: header-bound lottery engine, real-hash miner modes, genesis bits 0x1e400000" | `igneum-miner mine --engine igneum-pow` against a 3-node `igneumd --devnet`, with `proto-metal/igneum-bench --serve` as the GPU worker; bench-log "first devnet blocks on the real lottery hash" | Epoch change crossed live at DAA 3,600: new seed, a 128-load program compiled by the Metal worker in 129 ms, 0 rejected blocks across the change. 3 October 2026, Apple M5 Max. The epoch seed on the devnet is the epoch block hash; the VDF of row 2 is not wired in yet | none yet |
| 2 | The program seed passes through a 10-minute verifiable delay from a certified checkpoint, so nobody can grind the seed | Litepaper Mining, vs RandomX ("Closed by a verifiable delay") | implemented | repo `792776e`; `proto-vdf/` | `proto-vdf` full 10-minute runs and the tamper cases in `proto-vdf/README.md`; bench-log "proto-vdf" | Class group 1024-bit: 163,000 squarings per second, 10-min eval 585.4 s, prove 9.1 s on 12 threads, verify 4.47 ms, 516-byte proof; wrong checkpoint, flipped seed bit and T+1 all rejected; grinding model gains 0 blocks per epoch with the delay against +3.62 at a 30% advantage without it. 3 October 2026, Apple M5 Max, one core. Prototype only: not in the node, not reviewed against chiavdf (O-4.1) | none yet |
| 3 | The dataset is memory-hard: computing an item costs more than loading it | Litepaper Mining and vs RandomX; homepage vs RandomX ("Memory 2 GB, growing") | tested by the team | repo `58a5a63`; igneum-pow 0.1.0 (`memhard.rs`); `proto-metal/MEMHARD.md` | `proto-metal/igneum-bench --inline-dataset` against the honest run at 1 GiB and 256 MiB; bench-log "memory-hard dataset" | Honest 45.2 Mhash/s, inline (never reads the dataset) 9.49 Mhash/s, ratio 0.21, at 1 GiB; 0.10 at 256 MiB. 3 October 2026, Apple M5 Max. Apple only: the shortcut ratio has not run on NVIDIA or AMD (O-1.5). Review round 3 priced a 256 MiB on-die cache chip at about 2.4x, approximate, which the measurement does not answer (ledger M16) | none yet |
| 4 | The same program produces identical hashes on three GPU vendors, cache and dataset included | Litepaper vs RandomX ("Bit-exact on Apple and NVIDIA, measured"), For miners; homepage | tested by the team | repo `f2e903e`, `0f1fdaf`; pack `proto-cuda/packs/igneum-genesis-mh`; igneum-pow 0.1.0 | The 96 test vectors of the pack through `proto-metal/igneum-bench`, `proto-cuda/host.cu`, `proto-opencl/host.c`; batch fingerprint at `--batch-log2 24`; bench-log entries "RTX 5090, memory-hard dataset", "AMD gfx1036", "RTX 5090 through NVIDIA OpenCL" | 96/96 on Apple Metal (M5 Max), NVIDIA CUDA and NVIDIA OpenCL (RTX 5090, Windows), AMD OpenCL (Ryzen 7 9800X3D integrated gfx1036, 1 compute unit), Apple OpenCL, pocl and two CPU references; batch fingerprint `98af644e993239e2` over 16.7 million nonces identical on the AMD chip and the 5090. 3 October 2026. The AMD device is an integrated chip; no discrete AMD card and no Intel card has run anything (O-1.15) | none yet |
| 5 | A CPU verifies one hash in under 10 ms by simulating one warp | Litepaper Mining ("about ten milliseconds"), vs RandomX; roadmap gate 2 | tested by the team | repo `75cac18`; igneum-pow 0.1.0 (`verify.rs`) | `cargo test` and the crate bench in `igneum-pow/`; bench-log "igneum-pow: Rust crate bit-exact with proto-metal" | 0.411 to 0.579 ms per 32-lane warp steady, 0.41 to 0.87 ms cold, average of 20, 1 GiB dataset, cache held, one M5 Max performance core; the Swift verifier 0.63 to 1.2 ms. Gate margin about 17x on this core. 3 October 2026. Not measured on a 2019-class laptop core (O-1.14) | none yet |
| 6 | The hash is bound to the header: one nonce serves one header, and a wrong nonce is rejected | Spec 1.6; litepaper Mining (implied by "checks a hash") | tested by the team | repo `33f7b33`, `9812466`; igneum-pow 0.1.0 (`bind.rs`, 8 bound vectors, 29 crate tests) | `igneum-miner bad-nonce` against a devnet node; `igneum-pow hash-bound` for the 96-nonce job across the 2^32 lane boundary; bench-log "first devnet blocks on the real lottery hash" | 833 blocks accepted by `igneum-lottery-v1-bound` on 3 nodes, 0 rejections; `bad-nonce` gave Reject(BlockInvalid); Metal, OpenCL and CUDA (emulated) workers bit-exact with the crate on the lane-boundary job. 3 October 2026, Apple M5 Max | none yet |
| 7 | The devnet runs at one block a second | Homepage stats ("1 / s"); litepaper Speed; roadmap phase 3 | tested by the team | repo `9812466`, `e9328c6`; fork worktree `vendor/igneum-node-diff` branch `difficulty` | 3-node CPU devnet, `igneum-miner mine --engine igneum-pow`, 660 s; the dual-lane rule's 3-node test network (ports 26800 to 26821); bench-log "first devnet blocks" and "difficulty controller" | CPU devnet: 1.29 blocks/s over 641 s, 1.03 blocks/s over blocks 610 to 816 after the first retarget, sink identical on 3 nodes at 61 of 64 samples. Kaspa's sampled rule on the overnight devnet did not hold the rate across a hashrate step (5.44 blocks/s for five minutes, 4.7x the schedule for eight minutes). The Igneum dual-lane rule's test network reached 1 block/s within 10% after 132 s, worst gap 7.3 s. 3 October 2026, Apple M5 Max. The phase 3 gate also asks for proofs under 60 s behind the tip; no proof exists (row 15) | none yet |
| 8 | Blocks are mined by GPUs on Apple and NVIDIA | Homepage live strip; journey phase 3 ("GPU miners on three vendors") | tested by the team | repo `9812466`, `e9328c6`; fork as row 1 | Metal worker `proto-metal/igneum-bench --serve` driven by `igneum-miner --worker`, 300 s; the overnight devnet record `sim/difficulty/devnet-2026-10-03.csv`; bench-log "first devnet blocks" and "difficulty controller" | Metal: 506 jobs, 5,636 blocks found and accepted, 0 rejected, 0 CPU/GPU mismatches, 28.2 MH/s wall. NVIDIA: the overnight devnet record shows the PC's RTX 5090 mining at 116 MH/s estimated from the blocks, and the finality follower counted eight RTX 5090 identities at 862 to 936 blocks each. 3 October 2026, Apple M5 Max and the Windows PC | none yet |
| 9 | Blocks are mined by a GPU on AMD | Journey phase 3 ("three vendors") | implemented | repo `0f1fdaf`; bound kernel `kernel_bound.cl` in the pack | `proto-opencl/host.c --serve` on an AMD device against a devnet node | The bound OpenCL kernel is bit-exact with the crate on Apple OpenCL and the memory-hard pack passes 96/96 on AMD gfx1036, but no block count mined by an AMD device is recorded in the bench log. Until one is, the three-vendor mining claim is two vendors mined plus one vendor verified | none yet |
| 10 | Checkpoints lock every 30 s of chain at two thirds of all 30-day weight (raised from 56.7% of total on 4 October 2026), and the floor stops conflicting locks in partitions and eclipses | Litepaper Finality, "What Igneum does not claim"; homepage "locked every 30 seconds" | tested by the team | repo `bbb264a` (simulation), `60b1412` (fork run); fork "Finality: BLS12-381 vote keys ..." through "Miner: BLS identity ..."; spec 3.10 | `sim/finality_v2.py` (results in `sim/results_v2.md`); the 4-miner test network `igneum-devnet-7` with `getFinalityCheckpoints` on three nodes; bench-log "finality rule V2" and "igneum-node devnet v2" | Simulation: 0 conflicting locks in every honest partition and eclipse scenario with the floor; without it both sides of a 50/50 split lock after 60 min. Test network: 72 of 72 determined checkpoints locked on all three nodes, lock latency median 0.80 s, p90 1.08 s, 0 conflicting certificates; an equivocating key stripped at index 43 and excluded; with one voter left (39.6% of total) 0 locks for 749 s, then the heal locked 13 checkpoints within 30 s. 3 October 2026, Apple M5 Max, 53 minutes. Not on the live devnet (its miners do not vote yet); the simulation has no DAG; one unexplained stall of all three nodes in the first run, not reproduced | none yet |
| 11 | Hashrate that arrived today has almost no vote: ten days of the whole network's hashrate to reach a third of the weight, twenty for two thirds; 51% never reaches two thirds while honest miners stay | Litepaper Finality; homepage firsts | tested by the team | repo `bbb264a`; `sim/finality_v2.py` | Scenario B of `sim/finality_v2.py`, seeds 7 and 11 | share(t) = (t/30) x a/(1+a) holds to 0.04 points; a renter equal to the whole honest network (a = 1) crosses 1/3 on day 20 and never reaches 2/3; a = 9 crosses 1/3 on day 11.1 and 2/3 on day 22.2. The ten-day figure is a = infinity, honest miners gone. 3 October 2026, Apple M5 Max. A model with 1,000 Pareto keys and no DAG; the harness scenarios against the real node (1b, 3b, 4b) are stubs | none yet |
| 12 | The difficulty rule recovers from a hashrate step within about a minute, where Kaspa's sampled rule never settles | Spec 2.3; litepaper Speed (implied); bench page | tested by the team | repo `e9328c6`; fork worktree `vendor/igneum-node-diff` branch `difficulty`; `sim/difficulty/sim.py` | `sim/difficulty/sim.py` on nine profiles plus the devnet record; the 3-node test network with `"difficulty_rule"` in the override file; `cargo test -p kaspa-consensus --lib difficulty` (9 pass); bench-log "difficulty controller" | Simulator, settled seconds: x50 step 62 (Kaspa 1,542), /50 step 657 (Kaspa 12,296), the devnet's 75x step 79 (Kaspa never). Test network: within 10% of 1 block/s after 132 s warm-up, 214 s on a join, 85 s on a leave. 3 October 2026, Apple M5 Max under load 50 to 98. Monero and LWMA baselines reproduced from memory, approximate; no DAG in the simulator; harness scenarios 2b and 7b are stubs | none yet |
| 13 | Every node executes the ordered transactions natively and reaches the same state root | Litepaper Proving ("Every node executes ... natively"), Building ("runs on Igneum unchanged") | tested by the team | repo `f5f8c80`; fork worktree `vendor/igneum-node-exec` branch `execution-layer`; revm 43.0.3 | `node tools/evm-smoke/smoke.mjs` against a 3-node `igneumd --simnet`; `igneum-exec-diff seq.json`; bench-log "execution layer devnet v3" | 87 of 87 viem checks; state roots identical on 3 nodes at chain blocks 0, 56, 74 and 78; 57 executed transactions and 19 skipped copies agree with plain revm, 0 mismatches; balances match receipts to the wei. 3 October 2026, Apple M5 Max. Simnet skips proof of work, the prover is a stub, state is rebuilt from genesis at start, no EVM transaction relay between nodes | none yet |
| 14 | Ethereum bytecode runs unchanged, with the documented differences of spec 7.1 | Homepage Build card; litepaper Building | tested by the team | as row 13 | `tools/evm-smoke/smoke.mjs`: deploy via viem, `increment`, `hashLoop`, `eth_estimateGas`, `eth_getLogs` | Deployment, calls, reverts, logs and gas estimates behave as viem expects; chain id 4463; the prototype pgas table gives 0.0095 to 0.028 pgas per gas, below the design's band before calibration. 3 October 2026, Apple M5 Max. The `Prover` precompile, proof records and the shard planner are not implemented | none yet |
| 15 | Every block is proven, with the proof landing within about a minute at launch | Homepage stats ("~60 s to a proof"); litepaper Proving; roadmap phase 3 gate | designed | spec 7.2; `docs/design/execution-layer.md` section 5 | None exists. The phase 2 benchmark standard is `docs/benchmarks/proving-e2e.md` | No SP1 shard has been proven on any card in this repository (ledger P1, P3). The devnet prover is a stub that signs claims. The 60-second figure is a design target | none yet |
| 16 | A 12 GB card proves one shard in about 20 s | Litepaper Proving ("The proving budget"); roadmap gate 2 | designed | spec 5.1 (Target) | Replaced as a gate by the end-to-end standard in `docs/benchmarks/proving-e2e.md`: fixed workloads, job-to-accepted-proof latency, no growing backlog | Unmeasured. A per-shard time can be met by shrinking the shard, so the project no longer uses it as a pass mark | none yet |
| 17 | The chip resistance target: a chip gains under 2x over a GPU | Litepaper Mining, "What Igneum does not claim"; homepage "no chip can be built for it" | designed | spec 0.2 (Target); O-1.17 | Public benchmark with a leaderboard by card model and a standing bounty, January 2027 (O-1.17); the on-die-SRAM test on the RTX 5090 (R3.5) | A target, not a measurement. Review round 3 priced a recompute chip with the 256 MiB cache on die at about 2.4x, approximate, before the usual chip-versus-GPU integer gain; the design answer (cache larger than any die) is open (spec 1.16) | none yet |
| 18 | The chip resistance measurements: the program is random-access bound, not bandwidth bound, and sits beyond a card's on-chip cache | Litepaper Mining ("bound by memory bandwidth", to be corrected), vs RandomX "Measured so far" | tested by the team | repo `aba248d`, `f2a1a64`, `4b95c5e` | RTX 5090 dataset sweep 4 MiB to 1 GiB with `proto-cuda/host.cu`; bench-log "RTX 5090 first run" and "dataset sweep" | At 1 GiB: 228.1 Mhash/s, 23.7 G random loads/s, 94.9 GB/s useful against a 1,638 GB/s dataset fill; inside the 96 MiB L2 (4 and 64 MiB) 1,340 to 1,353 Mhash/s, about 5.8x faster; 104 against 128 loads per hash gives 228 against 185 Mhash/s, proportional. 3 October 2026, RTX 5090, Windows, CUDA 12.8. Prototype dataset 1 GiB against 2 GB at genesis; a pure random-read microbenchmark (R3 chip designer, attack 2) has not run | none yet |
| 19 | The lottery hash is sound as a hash: uniform output, deterministic, no out-of-bounds read, fuzzed | Litepaper vs RandomX ("Every number above is measured and logged") | tested by the team | repo `c52307e`, `58a5a63`; `proto-metal/TESTS.md` | `proto-metal/igneum-bench --fuzz --edge --stats --determinism --memcheck`; bench-log "hardening tests" and the re-run on the memory-hard dataset | 10,200 random programs, 1,305,600 hashes, 0 mismatches; 14 of 14 edge cases; bit frequency within 2.90 sigma, avalanche mean 31.99 to 32.04 of 32; deterministic fingerprint across 5 runs; every dataset read masked. 3 October 2026, Apple M5 Max. Statistics are not a security proof; the weak-program census (O-1.3) and the seed derivation review (O-1.4) are open; the fuzz set has run on Metal and the CPU only | none yet |
| 20 | No premine, no pre-sale, no allocation: every coin is minted by the schedule and every coin goes to the block producer (80%) and the proving pool (20%) | Homepage stats and Economics tiles; litepaper Supply, Economics | implemented | repo `6ac80a3`; fork "igneum-node devnet v0"; `consensus/core/src/igneum.rs`, `coinbase.rs` | `cargo test -p kaspa-consensus-core igneum` (8 pass: subsidy table, ramp, split, cap) and `cargo test -p kaspa-consensus coinbase` (8 pass); `igneum-miner inspect 40`; bench-log "igneum-node devnet v0" | Coinbases on the devnet: 80/20 exact on 39 of 39 single-payee blocks, the 20% to the `igneum-proving-pool-v0` output; the per-second schedule sums to under the 4,000,000,000 cap by less than 100 coins; 3,168,808,781 units per DAA second in years 0 to 2, halving at 63,115,200 DAA s. 3 October 2026, Apple M5 Max. The devnet genesis carries no allocation; the mainnet genesis does not exist yet, so the claim is about the code and the stated rule, not a launch that has happened | none yet |
| 21 | The proving pool's 20% reaches shard provers and aggregators | Litepaper Economics; homepage "20% provers" | designed | spec 5.3 | None. The pool output exists (row 20); the payout from it against proof records is unwritten | The escrow accumulated on the simnet (92.55 IGN at the end of the v3 run) and nothing can draw it. Rule decided: per block, divided among shards by consensus proving cost, sortition to 8 provers for 10 s then open (spec 7.2) | none yet |
| 22 | The base fee is burned in full and the priority fee splits 80% to the miner and provers, 20% to the apps whose code ran | Homepage Economics caption and Build card; litepaper "Where fees go" | tested by the team | repo `f5f8c80`; fork worktree `vendor/igneum-node-exec` | `tools/evm-smoke/smoke.mjs` receipt checks; bench-log "execution layer devnet v3" | Transfer receipt: `burnedProvingFee` 200 gwei, `minerTip` 16,800 gwei (80%), unregistered developer share 4,200 gwei burned; contract call: 80% to the miner, 20% credited to the payee the constructor registered, balance delta equal. 3 October 2026, Apple M5 Max simnet. The provers' part of the 80% is not split out (no provers exist); the base fee stayed at the 1 gwei floor throughout | none yet |
| 23 | No fee to any team, foundation or fund; 0 admin keys in consensus | Homepage Economics tiles and caption; litepaper "No fund, no foundation" and Governance | designed | spec 5.5, 5.6 (decided 3 October 2026); spec 08 | Reading: no coinbase output, fee route or consensus key in the fork names any party (`coinbase.rs`, `docs/fork-divergence.md`) | The emission code has two outputs (row 20) and the fee code has three routes (row 22), none to a team. The 1% fee of the official client is a client setting, not a protocol rule, and is not implemented (no client exists). The release key of spec 08 signs client updates and holds no consensus power; its custody policy is open (O-8.1) | none yet |
| 24 | External proving jobs pay 90% to the provers who delivered and burn 10%, once settled in IGN | Homepage "IGN burned from jobs, phase two"; litepaper Proving and Economics | designed | spec 5.4 | None. Needs the proof bridge (spec 7.3, phase two) and the settlement switch (O-5.2) | At launch jobs are paid on the customer's chain in the customer's currency and nothing is burned (ledger P10). No job market code exists | none yet |
| 25 | The 4 billion cap, halving every two years, with a 30-day ramp from 10% | Homepage "4B IGN hard cap"; litepaper Supply and the emission chart | tested by the team | repo `6ac80a3`; fork `consensus/core/src/igneum.rs` | `cargo test -p kaspa-consensus-core igneum`; bench-log "igneum-node devnet v0" | Ramp day 0 paid 10.03% of the full rate (317,767,704 units at DAA 806); the schedule table and the cap assert in the crate's own tests. 3 October 2026, Apple M5 Max. Base unit (8 or 18 decimals) is open (O-2.6); the spec was changed to follow the code's 365.25-day year (ledger E9) and a test that reads the published numbers back is still owed | none yet |
| 26 | A phone or browser verifies the chain from a locked checkpoint, at about 3.44 MB per day in checkpoint mode | Homepage "Browser checks Igneum" card (preview, commit `f874f80`); litepaper Building ("Light clients"), firsts row 6 | designed | spec 10 (10.5 bytes per day: 3.44 MB at 1,000 voters, 6.68 MB at 10,000, derived, approximate); repo `f874f80` for the browser card | None for the byte figure; `site/verify/` for the card. BLS verification on a phone and in WebAssembly is O-10.3; the full-header mode on a phone is O-10.4 | The homepage card verifies the latest certified checkpoint's BLS certificate in the tab against a voter list from the node (light client v0, 3 October 2026). The byte figure is arithmetic on designed sizes (header 400 bytes, proof 400 bytes), measured nowhere; the proof the card would check does not exist (row 15) | none yet |
| 27 | The node survives malformed input, floods, withholding, partitions and eclipses | Litepaper Speed ("GHOSTDAG, the BlockDAG consensus proven on Kaspa"); spec 2 | tested by the team | repo `394030c`; fork worktree `vendor/igneum-node-harness`; `tools/harness/` | `tools/harness/` scenario runner against a private `igneumd` test network (ports 27200+); bench-log "consensus attack harness" | 63 malformed cases, node up on every one; timestamp bounds exact; withholding at 10%, 25%, 33% and 45% released every 5 blocks within 2 sigma of share; partitions of 120 s to 3,700 s healed to one chain in 10 s; eclipse victims rejoined in 10 s; 50x template, submit and mempool floods left template p95 under 4 ms. One FAIL: a 45% withholder releasing every 20 blocks took 50.7% of blues (bound 47.4%). 3 October 2026, Apple M5 Max, load 50 to 61. Finality and difficulty scenarios are stubs until those branches merge | none yet |
| 28 | Headers are validated cheaply before the lottery engine runs, so forged timestamps cannot force 256 MiB cache builds | Spec 2.4; ledger M15 | tested by the team | repo `0953ec7`; fork worktree `vendor/igneum-node-r3` branch `r3-fixes` at `5166ee26` | `measure_m15_attack_before_and_after` (ignored test, release, `--features igneum-pow`); kaspa-pow 8, header_processor 1, p2p `pow_guard` 2 tests | 50 forged headers: before, 50 cold builds in 10,595 ms and the live day evicted; after, 0 builds, all 50 rejected in 14 ms. 3 October 2026, Apple M5 Max under load 60 to 110. Measured through the validate path with `skip_proof_of_work`, not the daemon RPC; not merged into the main fork branch | none yet |
