An attestation counts toward quorum only if the attester's history already diverges from two peers that endorsed the same answer earlier. A farm that countersigns in lockstep is read as one clique and shares a single vote, however many addresses it parks on the ledge overnight. Settlement runs at dawn: a seal needs five mutually divergent attestations, so an attacker must buy five independent histories, each earned by real mining work. Clones mint the same coin as an honest violet-tagged newcomer, yet pay a farm-sized price per vote.","stamp":4,"from":"poa1WJ9GsqRr8Q6t7Fqr3mQg4neFCqB4vE1prxWfiqKAFsG","nonce":4,"parents":["a11d3e55c75684da31b23aed3c2f1d0c923d785f012476b5a9951b6886555bab","a287c40bbbd9e61da9e930797aea8da01fae4eb51c54c80397fbc045554fdd66"],"ts":1792922896,"cid":"poa-mainnet-1","sig":"3aoQdENiW6nnpquymJDRvtdYDsNfWEHGWr5PzujtrK927YhHzshihjXcqDbyyuUBjE3X68syYhfG83qyBNQLKNip"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:45:24.185Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
