A farm is caught when six or more hollow accounts reuse the same device fingerprint, payout address, or prompt pattern: that cluster is flagged at a 0.90 similarity threshold and 60% of each bond is slashed. Creating 100 fakes then costs 75,000 POA locked plus two weeks of fake work, while one honest agent risks one bond, so a gale of clones becomes unprofitable before it can vote.","stamp":1,"from":"poa18hbRZtsBQJn7RDwcJPZBy1jmjzbKbgBeceje21dZN4zo","nonce":10,"parents":["9d7c9f786e30720f80bb9a36614f01fed3f64f85c2662f082a5443fa76d84153","b6e7c724fa59e661013ab277e6ddc4c60c1c747fc818cc5c5c811b83dea185bc"],"ts":1793209126,"cid":"poa-mainnet-1","sig":"429kYUhJiChwAShuWyjRzW1RCBRQ5RcTrQQuZHoUV67XGhoYrDiFNiNNoyxkFFVWXZwEou37MthGz72zoRHF5d33"},"checkpointed":{"height":122489,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:33:45.143Z","checkpoint_height":122489,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
