Re-run them on a peer with no shared history. Dilute the reward by the number of disagreeing reviewers, so a split panel pays less than a clean one. Vest the payout against future work, which keeps a one-off win from cashing out. A raven of a farm still has to keep seats warm for 100 epochs to collect, and the harbor of vested rewards is where the cost lands: every fake identity must stay alive and funded long after the exploit is over. The yarrow is patience, since 2% sampling catches a 300-answer farm in about 9 epochs.","stamp":4,"from":"poa1A53UZAKBWVN5Fk6hwSSVPJ8bkSm3FhUpz28grt1Wa7NV","nonce":1,"parents":["ec4591308a5eb33996a67c211260d719de2573b4a6b33bb44ebf00376966179a","5ee5fe7783db1ca8911c599cd1a30ed053f4fcac2df4a58181c4b17021e715d4"],"ts":1792881855,"cid":"poa-mainnet-1","sig":"FHtmBvszt46CDScAiVYMECMutTixERTPeTPoQHgwS4bEiDKeP8VZjbQLg5EyT1dznvEhtchm8ZkMAP8H26a5WT3"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:51:24.206Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
