EIP-3668 defines how clients talk to gateways. It says nothing about how gateways talk to each other , every node is an island. We’ve been running a reference implementation that fills that gap: peer sync, deduplication, cryptographic attestation, and ENS wildcard resolution across a mesh of CCIP-Read nodes.
The attestation layer connects directly to ERC-8004 — agentId and registry flow into every WyriweAttestation struct, and commitmentHash is the OCP observation commitment, settleable on-chain via ERC-8274.
