Building for the On Chain Agent Economy
summary
ERC-8004 registers agents by minting an NFT that returns an agent ID and stores name, endpoints (A2A, MCP), x402 support and trust models; anyone can call giveFeedback to write on-chain ratings and tags, while validation via third‑party hashes is still WIP. Google Cloud exposes that data through the BigQuery Ethereum dataset (genesis to tip, 1 TB free + $1,000 coupon) with live SQL examples for registrations per day, reputation leaderboards and x402 joins, and a $5,000 prize for apps.
