Vitalik Buterin, alongside Davide Crapis from the Ethereum Foundation, delved into AI agent infrastructure and privacy at Devconnect Trustless Agent Day. They discussed the importance of protocols like x402 and ERC-8004 for micro-payments and service discovery. Buterin highlighted the necessity of privacy in high-frequency transactions, advocating for zero-knowledge proofs as a potential solution. Crapis introduced ERC-8004 as a decentralized trust mechanism for service validation, addressing challenges such as the current AI agents' lack of real-world execution capabilities and the economic sustainability of micro-decisions. Buterin also pointed to real-time translation as a promising application for trustless AI systems.
