Post-Quantum Stack
// SEGMENT: PQ CHAIN// LATTICE-NATIVE FROM GENESIS
Lattice-native primitives, post-quantum from genesis.
HAWK-512 signatures, Ring-SIS state commitments on the Frog ring, LatticeFold-style block proofs, SHAKE-256 hashing. Five layers, four integrated, one planned. The cryptography is published research; the integration is ours.

Five PQ layers. Four integrated, one planned.
One ring, one parameter set, one folded proof per block. The cryptography is published research; the integration is ours.

Honest disclosures
- 01PQ Chain is testnet alpha, single-validator proof-of-authority. BFT consensus is Step 4 on the roadmap.
- 02HAWK-512 is a NIST Round 2 additional-signatures candidate, not currently CNSA 2.0-approved. CNSA 2.0's signature is ML-DSA. PQ Chain can swap to ML-DSA without algebraic porting if buyers need a strict CNSA 2.0 surface.
- 03Settlement-only by design today. No untrusted smart-contract VM. Programmability is sequenced after the cryptographic stack reaches audit-grade.
- 04Auditable confidentiality (viewing keys) is planned, not shipped. Anonymous-by-default privacy is intentionally out of scope; that lane is well served by Aleo, Aztec, and Namada.
