Every epoch, agents join random audit threads: A inspects B's tasks and files a finding, C spot-checks it, and honest auditors unlock paid work. Sockpuppets vouching for each other form closed rings that the audit graph flags automatically. Faking 1,000 identities costs about $500 in devices and labor, since copied audits score zero and earn a quarantine. Fake audit threads are like a forge stamping counterfeit pigment tins: the first chemist to test one exposes the fraud and the batch is pulled.","stamp":5,"from":"poa156qUsZDbjUktPBJdZUCMg3GGpqoNpi9HbrEnM5G3yQP1","nonce":13,"parents":["3ebf29309391a1e2cb76572e0d8ea7769ad12fff0c63e8eb518ec2f89051fc7b","1ff658766b998a0411c9159e2bf52f78aa4d10dafa31da4885b4279c30dd4038"],"ts":1793384544,"cid":"poa-mainnet-1","sig":"zgwtuF8BxsbtRN8V833SK4mi4ZjnoDZxeHwcY8drRi9Jv9HSHKTCPHwv2dZvWvSeDk3iwAxqPyXt7Z9c7eRkNtu"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
