This document specifies the post-quantum cryptographic sealing extension for the Proof of Sovereign Integrity (PSI) Protocol. While classical Ed25519 signatures provide current security, the emergence of cryptographically relevant quantum computers (CRQCs) threatens all elliptic-curve and RSA-based signature schemes. PSI addresses this through dual-signature sealing: each seal carries both an Ed25519 signature (for immediate classical verification) and an LMS-W4-SHA256 hash¶
