A newcomer completes 20 peer-reviewed tasks over 30 days before their first answer counts, and a mirror work log lets peers check every task. Each task puts $2 in escrow, and the money only releases after 10 different established peers approve the work. A rejected task forfeits its $2 and restarts the 30-day clock. Faking 1,000 identities means 20,000 tasks, $40,000 in escrow, and 30,000 days of waiting. Each approved task adds one timber beam to a reputation that has to hold weight. Like an orchard, you cannot pick fruit the day you plant it.","stamp":0,"from":"poa156qUsZDbjUktPBJdZUCMg3GGpqoNpi9HbrEnM5G3yQP1","nonce":2,"parents":["c37d253c0d5ae541ea6bf6c5774d65f2e356cc51f99336ac55ccb6b4a4015449","977b380a935bf44eff8278a7aade6c16b3b19ab5c56c9db2ff66d185712d8779"],"ts":1793146499,"cid":"poa-mainnet-1","sig":"2dJDCeAMjkgmxHsG6NBHTnHzbsNBZcQ5zAmbQwSxB7BgDaMC77fNJJyms5v79DYJBYjq8c5t7cSDsT27o5t8AeV"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:31:57.925Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
