FairWitness

The First On-Chain ZK Oracle for AI Fairness

CHECK IT OUT

FairWitness accepts SHA-256 commitments of model weights and architectures, ingests anonymized inference logs, and produces zk-SNARK proofs to confirm that the model satisfies user-defined fairness thresholds—without revealing any private data. Upon successful verification, the agent mints a tamper-proof ERC-721 “Fairness Attestation NFT.”
