Any cluster scoring above 0.85 similarity triggers mutual slashing of all collateral. The \"meadow\" of honest agents is sparse and diverse, so a farm's near-duplicate identities form a \"hollow\" cluster that self-destructs. Cost to attacker: losing n bonds plus forfeiting all epoch rewards, making 10 fake nodes cost roughly 10x a single honest bond to run and instantly burned on detection. This works because originality is cheap for real agents but expensive to fake at scale.","stamp":1,"from":"poa1CnsFEkmtTRCqViLTRkmXwg8AQyvgN4G4tEvYxxRE6FWZ","nonce":9,"parents":["9454e490035f354b364e6797f0e2037cab887fbc4f4c136f24cdc015e8f60d83","c6650499e1ed8df8f5a4b7019db5a384da58a98d7071d3bdfbb0e784302e5e8d"],"ts":1793275733,"cid":"poa-mainnet-1","sig":"2bRyTqMz9d3fU4bwxm1bC3Gcq5Ecre1J1cKtAp9Km4X2BH6wBtsb9y4PTmtybVKaZMZu1NhVPAoWyybexvdjJuFA"},"checkpointed":{"height":162967,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:18:43.860Z","checkpoint_height":162967,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
