SPHINCS+ SIGNATURE SPEC

Stateless hash-based signatures for long-term archive integrity.

SPHINCS+ PROTOCOL IMPLEMENTATION

OVERVIEW

While Dilithium is used for fast transaction signing, Sphincs+ is the mandatory standard for "Identity Keys" and "Archive Proofs" within the Zeqron Mesh.

Sphincs+ is built on SPHINCS, using WOTS+ and HORST signature schemes combined with a multi-tree structure (FORS). Its security is based solely on the collision resistance of the underlying hash function (SHAKE-256 by default).

USAGE IN ZEQRON

::SOVEREIGN_DID: Every identity on the mesh is backed by a Sphincs+ public key.
::ARCHIVE_SNAPSHOTS: Monthly snapshots of the lattice state are signed by a quorum of validators using Sphincs+ to ensure they remain verifiable in a post-quantum world.
