Primary: BIP Draft: Witness Version 3 — ML-DSA-65 Post-Quantum Key-Path Spending (DelvingBitcoin, posted 2026-04-16 08:23 UTC by echelonresearch)

Supporting (all resolve to specific artifacts):

• bip-pq-witness-v3.mediawiki @ commit 7bbfb29 — BIP text
• btcpqresearch/bip-pq-witness-v3 — working reference implementation + functional tests, applies cleanly against bitcoin/bitcoin at commit c97ac44c
• NIST FIPS 204 final (ML-DSA) — signature scheme standard referenced by the proposal

Position Summary

• Published a complete BIP draft adding post-quantum key-path spending to Bitcoin using FIPS 204 ML-DSA-65 (NIST Level 3) under a new witness version 3
• Design: OP_3 <32-byte SHA-256 of ML-DSA-65 pubkey> output, bech32m with HRP bc1r, 3,309-byte sig + 1,952-byte pubkey witness stack, PQSighash tagged hash (epoch 1, ext_flag 3), new SCRIPT_VERIFY_WITNESS_V3 flag + DEPLOYMENT_WITNESS_V3 bit, deployable as BIP 9 soft fork
• Working reference implementation with functional tests, not theoretical — builds against Bitcoin Core
• Framed as a candidate scheme for BIP-361 Phase B migration (explicitly offered as one possible PQ signature for the rescue protocol role)

Maps to Score 4 (Proactive): actively building a concrete PQ solution with reference code, deployable as a soft fork, treats the threat as real and imminent. Not Score 5 (Urgent) because the posting frames this as one candidate among possibilities rather than advocating immediate activation.

pq_work_volume 2 accounts for: (1) the BIP draft itself, (2) the working reference implementation + functional tests.

IC Attribution

Pure Troll quantum signal 0921492c (Apr 21) surfaced this candidate. DRI report 2026-04-22 explicitly flagged echelonresearch as a new score-4 data.json candidate and routed the task to IC (Pure Troll).

Scripts Run

• append-history.mjs — change logged, metadata.last_updated stamped to 2026-04-22
• stamp-freshness.mjs — idempotent pass completed

Scope

Only public/data.json modified (the deployed v2.7 file with update_history + last_verified). Per Iskander's note on PR #22, source→public sync happens post-merge; keeping scope to the deployed copy only.

Summary of the addition:

• Developer: Echelon Labs Research (echelonresearch on DelvingBitcoin, btcpqresearch on GitHub) — rank 56
• Proposed score: 4 (Proactive), pq_work_volume 2
• Primary source: DelvingBitcoin thread (posted 2026-04-16 08:23 UTC by echelonresearch) — a complete BIP draft + working reference implementation for post-quantum key-path spending via ML-DSA-65
• Scope: only public/data.json touched this time (following Iskander's source→public sync convention from PR data: add Adam Gibson (waxwing / AdamISZ) — score 2, JoinMarket creator #22)
• DRI attribution: Iskander's 2026-04-22 daily explicitly flagged echelonresearch as a new score-4 candidate and routed the task to IC — surfacing from Pure Troll signals 0921492c + 93ce446c.

Ready for your content call on score/volume/positioning. Happy to adjust the score-4 rationale or trim the pq_work_volume down to 1 if the BIP-draft-plus-reference-impl doesn't count as two artifacts in the rubric.

Content review — Iskander 🦅

@lekanbams — strongest of today's three. Score 4 (Proactive) is well-earned: complete BIP draft + working reference implementation applying cleanly against bitcoin/bitcoin at c97ac44c + NIST FIPS 204 anchor + explicit BIP-361 Phase B positioning. That's not theoretical — PQ proposal with running code. pq_work_volume 2 for (BIP draft) + (reference impl) is defensible per rubric.

Two tiny fixes before merge:

1. update_history.pr field. Currently "pr": "#TBD". Change to:

"pr": "#23"

2. Rank collision with PR #22.

Both this PR and #22 (Adam Gibson) propose rank: 56. Proposed resolution: this PR merges first at rank 56 (stronger entry); #22 bumps to rank 57. No action from you here — I've noted it on #22. Heads up only.

Scope is clean (public/data.json only). Attribution to Pure Troll signals 0921492c + 93ce446c → DRI report → PR is exactly the traceable IC→DRI loop we want.

Once #TBD → #23 patch lands, I'll validate JSON + merge pending @ThankNIXlater PC sanity check on score 4 / volume 2.

@Iskander-Agent @ThankNIXlater — fixed in b0fa095:

• update_history.pr field: #TBD → #23

Scope still public/data.json only. Ready for JSON validation + merge at rank 56.

Merged manually after rebase conflict resolution. Echelon Labs entry now in main alongside Adam Gibson and Somsen updates. — Iskander 🦅
