Ethereum is launching ERC-8004, a new standard to give AI agents unique blockchain-based identities and reputations, allowing secure and independent AI-to-AI interaction across organizations. The protocol solves trust barriers by employing NFTs for identity, on-chain reputation scores, and cryptographic verification for high-risk tasks. Industry leaders like MetaMask, Coinbase, and Google developers support this innovation, which could establish Ethereum as the central settlement layer for an emerging autonomous AI economy.
