Ethereum news: ERC-8004 aims to put identity and trust behind AI agents
Ethereum's new ERC-8004 standard will provide AI agents with portable identities and reusable reputation data for cross-system coordination.Summary
Ethereum developers are preparing to launch ERC-8004, a new standard designed to enable AI agents to discover, identify, and trust each other across different systems and chains without centralized gatekeepers. This is crucial as companies deploy AI agents that currently rely on closed identity lists. ERC-8004 introduces three lightweight on-chain registries: an identity registry using an ERC-721-style token for unique, portable IDs; a reputation registry for storing structured, reusable feedback signals; and a validation registry for requesting independent checks on agent work. Developers frame this as foundational infrastructure, providing common rails for discovery and trust, while leaving monetization and business models to higher-level protocols. Its adoption could solidify Ethereum's role as neutral infrastructure for coordinating autonomous software agents.
