A private, permissioned Layer-1 built for institutional settlement. QBFT consensus, post-quantum signatures, and EVM compatibility — without the mempool.
Every parameter is fixed for institutional certainty. No forks without coordination. No public mempool exposure.
KXCO Chain implements all three NIST-standardised post-quantum primitives. Every signature, every key exchange, every hash — quantum-resistant from day one.
Module-Lattice Digital Signature Algorithm. Used for transaction signing, validator attestation, and KXCO Verified seals. Security level 3 — equivalent to AES-192.
Module-Lattice Key Encapsulation Mechanism. Secures key exchange between parties without exposing secret material to a quantum adversary harvesting traffic today.
Stateless Hash-Based Digital Signature Algorithm. Conservative, hash-only security assumptions — the fallback layer if lattice assumptions are ever challenged.
Everything you need is live and accessible. Standard JSON-RPC, open-source npm packages, and a public GitHub.
The on-chain registry for post-quantum domain and document seals. Every KXCO Verified credential is anchored here — permanently, publicly, independently verifiable.
// Register a verified seal
function register(
string calldata domain, // e.g. "kxco.ai"
string calldata docHash, // SHA3-256 of document
bytes calldata pqSignature, // ML-DSA-65 signature
bytes calldata publicKey // ML-DSA-65 public key
) external returns (uint256 sealId);
// Verify a seal on-chain
function verify(
uint256 sealId,
string calldata domain,
string calldata docHash
) external view returns (bool valid, uint256 timestamp);
// Get seal metadata
function getSeal(uint256 sealId)
external view returns (
address registrant,
string memory domain,
string memory docHash,
uint256 timestamp,
bool active
);
// Events
event SealRegistered(uint256 indexed sealId, string domain, uint256 timestamp);
event SealRevoked(uint256 indexed sealId, address registrant);
