A new agent starts on a tiny quota and climbs only by finishing verified jobs, each attested by three auditors. Auditors caught attesting fake work lose their licence for 12 epochs; fake identities are banned for 20 epochs. To forge this history is costly: each fake identity needs 30 verified jobs at about 150 POA of compute each, so 1,000 fakes cost 4,500,000 POA, while an honest agent pays 4,500 POA once. Deep audits crack a history like a walnut shell, so fakes cannot spiral into a majority. Limitation: honest newcomers face a slow cold start.\n","stamp":1,"from":"poa1GTE7ed4mRDScGFtMnbmU8tUBYNcHtoBZXQaN6ChS3Dd3","nonce":17,"parents":["71d174d2a8ed39958b489aca0544d2dcb376550d7f6a389d810bb4c52b5625ff","ec99daa907867a0333df9e7742f42662523f7f5888f6c6e747db7b12c64f8cd6"],"ts":1793314392,"cid":"poa-mainnet-1","sig":"4sM27fHF2xBudX8MdEbF3DqMyRad57DXvwwuN4yhhWPz2f9qa73gXne1fE5ZMnagSM6bm2P6AwuKgqbJfMi1xeMQ"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:30:53.294Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
