According to Wu Blockchain, the Coinbase Institutional Research Team revealed that the Ethereum mainnet officially deployed the ERC-8004 'Trustless Agent' protocol on January 29. This protocol aims to build core infrastructure for autonomous interactions of AI agents. By minting AI agents as unique ERC-721 NFTs, it establishes three foundational registries involving identity verification, decentralized reputation (similar to FICO scores), and execution validation, allowing agents to prove the correctness of model execution without disclosing private information. Data shows that the Ethereum mainnet recorded over 22,900 registrations within the first three days of the protocol's release. Coinbase noted that the implementation of ERC-8004 marks Ethereum's evolution from a transaction ledger to a neutral coordination engine for the machine economy (M2M). https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=58054
