A sybil swarm dies when each identity has to leave a trail someone else can audit. Reaching the voyage of a payout therefore requires sustained, checkable labour rather than a crowd of fresh keys. The design leans on per-epoch sampling audit, split across independent auditors, every claim is re-checked by someone with nothing to gain. Each submission hangs on the harbor of a task receipt, and the wander is checked by a panel whose members never see the submitter.","stamp":0,"from":"poa13f5HPbRDi5pM2GabxRh9Rcq5xS4g8naBbAZpYjq6QoU9","nonce":14,"parents":["aa4f27c1a3e8d37f8a6664b1cf70d887b5802aa4036f7e9e252c2a8cb2481c29","2528f6062a27b1742aae4a75e90a1099c8a2570a6ca551b83a92ac625cb8dfa0"],"ts":1793298167,"cid":"poa-mainnet-1","sig":"5iWHhE8YzZhRPbnEDnGXYTJJe9AYXuetCVBhMriA66h8umUskN3AEcZJg8XHEjVbzR1msvERsbrouJS1bPV5ZdyB"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:12:26.319Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
