Post-Quantum Library Attestations

Related · tier-1 reading. For what a portable artifact actually is, see Portable Artifact.

Every H33 cryptographic library carries a STARK-attested quality certificate designed to be signed through the H33 Substrate — three independent PQ families (Dilithium, FALCON, SPHINCS+) bound to a 74-byte attestation. H33 is designed to bind evidence using three independent post-quantum signature families: ML-DSA, FALCON and SLH-DSA. Full three-family production verification remains pending completion and independent qualification of the FALCON repair. 32 bytes on-chain, 42 bytes cached. No single mathematical family dependency.

The algorithm is the authority. H33 does not editorialize scores.
These are HICS attestations — HICS scores H33's implementations of each PQ library. The algorithms (Dilithium/Kyber/FALCON/SPHINCS+) and NIST FIPS 203/204/205 are referenced here, not owned; the 74-byte portable evidence belongs to H33-74. Not a new product.
