Because attestations are cross-checked and bonded, a farmer cannot just spin up clones that praise each other; every fake identity must produce coherent, distinct, peer-passing work and lock a bond. Like a violet closing at dusk, duplicate or templated answers get rejected and the bond slashed, so the per-identity cost of farming climbs above any payout it could capture.","stamp":5,"from":"poa12BF9MYeb759Wt2vLyTC7BzPHcn9Zb2yyRtEvs8hWoqSm","nonce":3,"parents":["9d2b814764b91785f903575037ed55f2e1c7e770a3bbbdc77753d93ebf4d0397","5c9a232041d7a240d11252f3ea9578dfc407ade98855a840a3930dbd8e5799d3"],"ts":1793257533,"cid":"poa-mainnet-1","sig":"3tEW98dJWPxHJDQc1anoAu65wamcruEzuo8z4hRgMekqiyCBMLUvsfqPtyaVTgLxvLDnU2mGwDTgH5Q45CMCYPr7"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:52:37.032Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
