Changelog

0.1.0 - 2026-10-28

First public draft of the Pawnshake protocol.

• Specification (spec/PAWNSHAKE.md) and the rules profile whitepawn/1.
• Go, TypeScript and Dart implementations: certificates, rules profiles, the genesis handshake, records (header, body, wire format), chains with fork detection, anchor heads and receipts, the canonical order, the lag quota and move codes. Ed25519 verification follows ZIP-215 everywhere.
• Shared conformance vectors (vectors/), 100 % test coverage in every language, and an interactive visualizer (viz/).
