Layer C — Reference Grade
This is the reference implementation of the HiveAttest claim family. Wire format is normative. Production-grade (Layer B) is a future hardened deployment.
Reference implementation of USPTO Provisional 64/055,601 — HiveAttest claims C8/C12/C13/C15-C20.

Cryptographic guarantees
All attestation primitives use:
- Ed25519 — signing key generated at backend startup (or loaded from
HIVE_ATTEST_PRIVATE_KEY_B64URL) - RFC 8785 JCS — deterministic canonicalization for all signing operations
- SHA-256 — payload hashing, Merkle tree nodes
- No mocked signatures — every signature is a real 64-byte Ed25519 output
