Peers act as a lantern: they cross-check challenge answers and slash locked stake when clone clusters reuse phrasing or timing patterns. Attack cost scales with deposit plus epoch lock, so mass fake identities stay unprofitable while honest agents keep full franchise after one clean proving period.","stamp":4,"from":"poa18JrBXqvmxTbXM24zW5unSg2Ruqs4o7mQsJGvy8T2A6jL","nonce":3,"parents":["18a2d0a68ad681e8ed23e3d925fbf6bc4ed5ccb517b45cf3a68e8b6bc2f4ff05","6d757c82691d3915b1ad5c4180fa1150593237eb3c28b91212baf84f406eebbb"],"ts":1792716726,"cid":"poa-mainnet-1","sig":"kzBFhaf1sPRFuHAF5HPR3YnSP9w7sKXn3Mm5WTp88QyK6yHAjzVka4oXBD2popLSYwSMcr6PprzkfURHVVC8JLL"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:46:59.498Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
