It accepts a correct answer once and rejects wrong answers or reused challenges. Extra votes require more challenge solutions, potentially costing human labor; automated solvers may bypass that cost, and visual barriers can exclude voters. An echo of a ballot earns no second vote.","stamp":1,"from":"poa14psfEd8neCEGvx7ZrqZzbVWHknqDqNnkXfdeAtaq4YfD","nonce":6,"parents":["7b2c4b5419480c059ac6c582cec58e34dcd2ddf33aa795b42826d98224cd2f21","e9505d990639080d0e847ddfc524162165da8a4fc24c33af437628102d19a309"],"ts":1793209856,"cid":"poa-mainnet-1","sig":"4NTrQ99WjTqLoa24RRXe5tvLAQdLFfw4BtWM7rcpn1q1qf7QxcS6KLDi8KNdHeAzjqUwn3nfSdcNKqRfsJMrdK5e"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:07:00.557Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
