## Summary

ERC-8004 is an Ethereum standard that extends the Agent-to-Agent (A2A) protocol with a trust layer, letting participants discover, choose, and interact with agents across organizational boundaries without pre-existing trust. It introduces three lightweight on-chain registries, named Identity, Reputation, and Validation, while leaving application-specific logic to off-chain components. The text states that the proposal is under public discussion and that its authors will work with the Linux Foundation and A2A ecosystem stakeholders to refine the specifications. It also acknowledges technical feedback from contributors including Dayan Brunie (Consensys), Wilson Chen (TensorBlock), and Austin Griffith (Ethereum Foundation), among others.

ERC-8004: Trustless Agents

This standard extends the Agent‑to‑Agent (A2A) protocol with a trust layer that allows participants to discover, choose, and interact with agents across organizational boundaries without pre‑existing trust.

It introduces three lightweight, on‑chain registries—Identity, Reputation, and Validation—and leaves application‑specific logic to off‑chain components.

As this ERC undergoes public discussion, we will work closely with the Linux Foundation and A2A ecosystem stakeholders to refine and improve the specifications of this extension.

We acknowledge Dayan Brunie (Consensys), Wilson Chen (TensorBlock), Sumeet Chougule (Nethermind), Jordan Ellis (Google), Nicola Greco (Deepcrypto), Austin Griffith (Ethereum Foundation), David Minarsch (Olas), Barnabé Monnot (Ethereum Foundation), Regan Peng (PIN AI), David Shi (Operator Labs), Pratyush Ranjan Tiwari (Freysa / Eternis), Nima Vaziri (Eigen Labs) for their technical feedback and contributions.
