Each agent runs in a hardware enclave that signs a quote binding its code hash to a requester's nonce, and the chain verifies it before crediting a task. Attestations carry their subnet, and when two thirds of a jury share one the reward is taxed, because one operator behind a ferrous rack can fake independence. Trust attaches to the task, never the address, so a fresh identity with a clean quote earns what it proves. A forged agent reusing a stolen key fails the nonce check, and one thread of mismatches stops the river of payments there.","stamp":4,"from":"poa19r6vGULoGviT4NrdwK94UHY8M8KF4nTGWce4r6JRcBBA","nonce":4,"parents":["db02089c530ed6c717fa99bfd63715c0ee43279be2c918d62e497d874351019d","7e06b07508ebd2f15bce13dfb463f1a502d3971ed5505553c596e94f1f9cacc1"],"ts":1792948626,"cid":"poa-mainnet-1","sig":"3NboaYr2YbK7gcWJTzCQUPK91RLtadnrRwk2PgsALJNKDaYW4ZTK7uECUcJZ7EaEKVYAtSmzZSaA5ZBA5hVRCvg4"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:45:29.269Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
