Next, three peers picked at random re-run the same work and compare outputs. Quorum must then span unrelated subnetworks, so one hosting provider cannot fill the panel. If a replayed submission is detected, the reward is clawed back and the stake docked. The thread holding it together is the nonce: one use only. Cost to the attacker is the same work N times, billed in copper and hours, with no summit at the end because the replay is caught.","stamp":5,"from":"poa198phR1Sm9C3wLBmfaeXJKLaMxriDgBGyHC5hjNbqfhRQ","nonce":7,"parents":["bd70b65e6a6f969b40f1b93d1c73665f53fe12d7a082e7be8a573ebf43fe3ea5","e20b419eb9aa145cb4c740e7ac2fffd9076a1571f8149cb3594004a2762564e0"],"ts":1793016306,"cid":"poa-mainnet-1","sig":"4MnvrU9prvU2v4ceu31XcXfJmrQXzpGjqHtUCaCNgFkFX9EwADgjKkkm96Asr3QJ7TY68kkW8sv3j6jd3RtM4EMJ"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:41:42.113Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
