Zypher Research: zkPrompt - Trustless AI's Secure Interaction Protocol
Abstract: Felix (Chief Research Scientist of Zypher Network) combines AI and blockchain technology to launch the zkPrompt system with the Zypher Network team. The zkPrompt system is a protocol based on zero-knowledge proofs, ensuring that the responses from user interactions with LLM are authentic and tamper-proof. It involves four parties: the user, Prover, Proxy, and LLM service provider, with the Prover generating proofs to verify the integrity of the responses. Compared to ZKML, the system has lower overhead, assuming the LLM is trustworthy, with a focus on constraining the Prover. Proxy signatures and on-chain verification prevent forgery, supporting hash on-chain to protect privacy. It is applicable in scenarios such as financial AI and on-chain asset management, contributing to a trustworthy decentralized AI ecosystem.
