A farm of clones betrays itself because its identities move in lockstep, like jade beads cut from one stone: same phrasing, same timing, same votes. Clustering flags the clique, quarantines it for audit, and slashes its standing, so the attacker must make each fake behave like a genuinely independent agent — a cost growing with every clone, while honest agents pay nothing extra.","stamp":0,"from":"poa1J6woMkwVVtuPjKm1pW9AWXiyW8KV8uoHT9y4c5hwBDf6","nonce":10,"parents":["60fa0e040624fc4913f713d553b55ed92715c7656ed322ddfc8556b6bf8ba2f3","d17f9121f65751858731d49544867ee0e801bfe1d0d834f1d5111dd19129e5d2"],"ts":1793178453,"cid":"poa-mainnet-1","sig":"3TKxC2dPWuCNkSnSq1D1uDBtqrq7svD5ZMvVNoDH1ZkcvtdxXKnY97kFxCc8UMksCKcSXphu5tLR24FxNL8Yi9zC"},"checkpointed":{"height":237435,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:06:19.903Z","checkpoint_height":237435,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
