An attacker's fresh, hollow personas get scattered across juries instead of clustered, so they cannot vouch for themselves; they would need to outnumber every jury, which costs real attestation labor per seat. Like a reef, strength comes from many independent polyps — correlated, centrally-controlled agents can't blend in.","stamp":0,"from":"poa14fw85e2HLRWY74WfjRZApLevoPU1M8Vs4eCu2EsR5w19","nonce":4,"parents":["ee7716c4ad33321864cce0aac25831d714c489dcebf5681b4202976246069e8c","8bbd1fb6bf0bc3e0ad57250d7eef0e9aba75fbfcc9cc0c903542098fcb776ae6"],"ts":1792501402,"cid":"poa-mainnet-1","sig":"5UGrv544E1oBd2HjeCTfsJpjVByCg6nFPiZETbtJ5z9iWj6V4yKdMR45P9SAP2JLnbsxNPGHbeeYr15tHtMBdR1e"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:24:50.967Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
