ERC-8004 registers three things for AI agents: ➡️Identity (who they are) ➡️Reputation (track record of behavior) ➡️Validation (proof of correct task execution) The Graph publishes ERC-8004 Subgraphs across 8 chains, creating a unified cross-chain directory of trust. An agent on Base can instantly verify the reputation of an agent on Arbitrum by querying a Subgraph. Without this infrastructure, every agent would need to scan raw blockchain data to check credentials. The network would grind to a halt.(The Graph)
