ERC-8004: Trustless Agents Standard.

Ethereum dev Davide Crapis has proposed ERC-8004 - a new standard to make AI agents interoperable across organizations in a trustless way.

From A2A to ERC-8004.
The existing Agent-to-Agent (A2A) protocol works, but only within trusted org boundaries.

ERC-8004 extends A2A with a trust layer, enabling agents from different ecosystems to discover and interact securely.

So, what’s inside?
The standard introduces 3 onchain registries:
• Identity - portable, censorship-resistant agent IDs.
• Reputation - attestations with flexible off-chain scoring.
• Validation - generic hooks for economic or cryptographic verification.

More complex operations like reputation scoring, data aggregation, or incentive mechanisms, are intentionally left offchain, keeping the system efficient and flexible.

And, as we see, ERC-8004 could unlock an open, cross-organizational AI agent economy.

Because It provides:
• A unified interface.
• Tiered trust models (to match different risk levels).
• More interoperability between AI systems.

As of today, ERC-8004 is still only a draft and waiting for feedback and refinement. But if the community embraces it, this standard could evolve into a foundation for trustless, collaborative AI on Ethereum.

What’s your opinion, guys?
