Abstract: Abstract: A computer-implemented method for quantum-resistant blockchain identity authentication is disclosed. An identity authority validates enrollment evidence, forms a salted identity commitment, and records a decentralized identifier, post-quantum public-key value, algorithm identifier, key version, validity interval, and credential status in a blockchain identity registry. For authentication, a verifier issues a fresh challenge containing a nonce, domain identifier, session identifier, and requested operation. A subject device binds the challenge, identifier, key version, and selectively disclosed credential data into a transcript hash and signs the transcript using a post-quantum private key. The verifier authenticates the subject only after verifying the signature, challenge freshness, domain binding, identity commitment, finalized ledger state, algorithm policy, validity, key version, and revocation status. A post-quantum key-encapsulation exchange may derive a transcript-bound session key. The method supports privacy-preserving audit receipts, cryptographic agility, key rotation, revocation, and threshold recovery.
