Blockchain-Enhanced Verifiable Secure Inference for Regulatable Privacy-Preserving Transactions

This research proposes a new system that combines blockchain (a decentralized ledger that records transactions) with zero-knowledge proofs (cryptographic methods that prove something is true without revealing the underlying data) to make AI model inference more trustworthy and private. The system verifies both where the input data comes from and where the AI model weights (the learned parameters that control how an AI makes decisions) come from, while keeping user information confidential. The authors demonstrate their approach with a privacy-preserving transaction system that can detect suspicious activity without exposing private data.
