Overview

BGIN coordinates multi-stakeholder dialogue on how DLT stacks, wallets, and operators migrate to post-quantum cryptography without inventing new algorithms. Work focuses on crypto-agility patterns, staged rollout, deployment gaps, and neutral measurement. Since September 2026 the workstream also carries BGIN’s coordination role for the Japan-hosted PQC Migration Prize (2026–2028): forming the evaluation committee, drafting the evaluation metrics and rubric, specifying a neutral crypto-agility testbed, and running a six-workshop series (Sep 2026 → Feb 2027) that feeds the host’s call text. BGIN does not select algorithms and does not run the competition.

Expected deliverables

  • Practical guidance on PQC migration for blockchain stacks
  • Crypto-agility architecture patterns (hybrid / algorithm agility)
  • Evaluation framework for the PQC Migration Prize — metrics register, rubric, and a “PQC-ready chain” definition in standards-ready vocabulary
  • Neutral, reproducible testbed evidence (BSafe.network concept) on pre-existing NIST-class signature schemes in Bitcoin- and Ethereum-mappable configurations
  • Call-text inputs delivered to the host (METI/NEDO) ahead of the planned January 2027 opening
  • Session outcomes and meeting reports from Block, GDC, and workshop meetings

Current status

The GDC26 Geneva breakout (3 Sep 2026) produced a Chatham House meeting report and session slides. The public coordination repository for the PQC Migration Prize opened in September 2026: governance, core outcomes (O1–O6), a 22-metric evaluation register, testbed scheme and harness specifications, and the workshop roadmap are all published as draft v0 for open review. The evaluation committee is forming — nominations are open, and the competition’s public discussion has its own category on the BGIN Discourse. Block 15 is the second workshop anchor: seating the committee, moving the metrics register from v0 to v1, and ruling on scheme scope. The SSR-co-located workshop on 13 Dec 2026 targets the call-text input package and a working definition of a “PQC-ready chain”. Earlier Block 12–14 reports remain on this hub.

Upcoming meetings

Block 15 sessionBGIN Block 1515 Oct 2026 · 09:20 - 09:50 · Room A

Keynote: Crypto Agility in the Quantum and AI Era

Opening keynote: Alex Pruden (CEO & Co-Founder, Project Eleven) on crypto agility as a design principle for digital assets and blockchain systems, and the practical work of migrating systems that secure billions of dollars in value.

Sets the Day 1 framing for the IKP PQC sessions that follow: deployment, crypto agility, and governance — not a new-algorithm contest — and connects the GDC26 findings to the competition evaluation work.

Block 15 sessionBGIN Block 1515 Oct 2026 · 09:50 - 11:20 · Room B

IKP: PQC Migration

Resource estimates and the ECDSA.fail community: what the benchmark numbers mean for migration timelines, and how they feed competition judging criteria.

Pressure-test the draft evaluation metrics (v0) and the open questions on reference hardware and block mix in public.

IKP: PQC Migration (2)

Crypto agility as a governance property and the NIST PQC signature migration path across Bitcoin, Ethereum, and other ecosystems — with NIST participation.

Seat the evaluation committee (Phase A), take the scheme scope rulings, and consolidate feedback for the metrics register v1 and the migration playbook.

WorkshopSSR 2026 co-located PQC workshop13 Dec 2026 · Baltimore

Rubric v1 and the working definition of a “PQC-ready chain”.

Call-text input package handed to the host ahead of the planned January 2027 opening.

WG callIKP Working GroupAnnounced on Discourse

Review open comments on the competition repository drafts (governance, outcomes, metrics, testbed).

Track evaluation-committee nominations and prep the Block 15 PQC sessions.

Coordinate cross-WG handoffs where needed.

How to participate

  • Nominate an evaluation-committee member — including yourself — via the repository issue template; conflict-of-interest disclosure follows the published policy
  • Propose or challenge a metric, or argue a scheme scope ruling (C-01…C-06), in the repository or on Discourse
  • Offer a testbed node — universities and neutral labs host BSafe.network evaluation nodes, separated from judging
  • Bring comments, corrections, and proposed “PQC-ready chain” definitions to the GDC26 report thread and to the Block 15 PQC sessions (15 Oct)
  • Work on Discourse (IKP and the competition category) — open to anyone, no membership required
