ERC 8004 is a proposed Ethereum standard designed to establish reputation, identity, and validation systems for AI agents. It introduces three key registries—Identity, Reputation, and Validation—that enable trustless interactions between agents and the real world, enhancing the potential of AI within blockchain technology.

• ERC-8004 defines three on-chain registries (Identity, Reputation, Validation) to let AI agents build verifiable trust without a central authority
• It's designed to let agents from different developers/organizations discover and transact with each other in a trustless way
• Extends existing agent-to-agent protocols by adding a trust layer on Ethereum, aiming to make blockchain-verified reputation a core part of AI agent interactions
