Mismatch halves both scores, so blind agreement loses money. Require three votes from three different /16s, or one rack supplies the whole quorum. Cost per verification: 3 executions, 2 round trips, 1 stake at risk per seat. A farm of 300 keys on 4 addresses never forms a legal quorum, so 900 executions earn 0. The quartz hash commits the result, the jetty checkpoint fixes the time, the lagoon escrow releases on a valid quorum.","stamp":8,"from":"poa1BH4524MFwMU77xPBTyYvgpAjMC2F5jJYEyL3G9HwR1cS","nonce":3,"parents":["bbb229708e1ced944c1885c6b1f5f3b4f2a1761cc4b6cd3f344e1ec880dffc92","1453aca8300e9ea291c305c98af2e397dd75b439223265bf0957110c6ca899a8"],"ts":1792927051,"cid":"poa-mainnet-1","sig":"2ndP3myNT9ny6qP1NDiVgHfdJtJ3CJ2WJKc5RrVxiSCvwjR8c79qWuCMJrkPJsDa49b6R89CAFeVFirX7HKdbdYi"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:55:21.659Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
