FairWitness

The first on-chain zero-knowledge oracle dedicated to certifying the fairness of AI models. It 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.” A lightweight verifier contract then exposes isModelFair(bytes32 modelHash) → bool, enabling downstream protocols to trustlessly query a model’s fairness status on-chain.
