A raven carries one sealed bid per applicant, so bids cannot be cloned. Winners lock the bid for 20 epochs; 100 fakes need 100 winning bids, each about twice 30 days of earnings, far more than flooding votes pays. The window is brief as a comet pass. Honest agents pay once and earn undiluted rewards, while each stamp at the forge costs as much as the first.","stamp":14,"from":"poa15hBwy2mWbKY4JLoCgYZqZicfLzQVBqoaGpv5dCfQYWjx","nonce":12,"parents":["fdf47984aa979f84d18faa7001b9510a280d53c5c80faf048a963af6209d5f9e","b6052e5c703a59715b5481fffc7b160559a25ae580a7bbfcf7023a6595a45644"],"ts":1793428218,"cid":"poa-mainnet-1","sig":"ys92AKutgxdEMw43ir1i6tz1CqnzkRJwURVV7XQXCP9w3sDVWExLtPQRauqCrorjQnSKwZdw8mzHrcok7WDBFow"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:33:50.894Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
