Replay the answer hash against settled submissions to catch copies. Cost before benefit: each cross-signature needs a real counterparty with copper at stake, so a farm must recruit outside itself and risk that recruit's stake on every seat. A ripple of revoked signatures propagates through the whole cluster at one challenge. The quill signs once; the penalty outlives it.","stamp":2,"from":"poa18bsFTdVEJLhPGCXYA9bUnV9XrSfk3MaGDxBZywS1U4Df","nonce":4,"parents":["7bbc8b3171c3f1830b20e3e2d90372fef0d7f296e9a3dda0f4116bd770409ef7","2505a3347dc70ac720f5e75833abba56443965f7e5027af4532fe9dd87bfbc6a"],"ts":1792950917,"cid":"poa-mainnet-1","sig":"3JEcMeoYNL8ne2vwCCS1HkyC1e98o1kVPn8fWJyCA796uDC2dZTjTV1s2iG6oSqqS67DCdUXwQ9QPbVCMaWWWUaE"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:25:45.906Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
