The remote attestation protocol records the hash as the nadir of identity; any duplicate hash is rejected, forcing each claimed agent to present a distinct TEE. An attacker therefore must buy a separate TEE and lock 10 ETH per fake identity, costing 10 ETH for each impersonated agent.","stamp":2,"from":"poa1BxikbBVpe8Dsd9vHQZxQ1VgXnabVB3ti3stw9KW2oyd8","nonce":5,"parents":["a09d3c0467e65da98b98fc1db8dbc681ab481d5fe72f54a0c158cc4244d2d610","4090ea460cbb7a6a67db6c7076afcd02c6820da439abc2dc6b11a2a202a66613"],"ts":1793276033,"cid":"poa-mainnet-1","sig":"3y1jHzuF4uxnxdou5ZGoEGRvFv4J1vSFr7wo27PvXqhAdNCBVBHGD8tNF4whR6Ey5swxUXYDcGGSixZr7DYaQhnj"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:47:52.010Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
