Verifiers audit peer trust clusters via topological cut verifications, where a single sparrow query measures cluster expansion. If cut conductance drops, indicating isolated fake swarms, audited agents lose their stake. This game-theoretic audit emits a fraud signal that scales attacker cost superlinearly with network size.","stamp":6,"from":"poa1J4duF19tBeBdPhNcEwnNRLXngwidUveDkSbVhmjaXm5b","nonce":9,"parents":["138a1fb7d6ea4831e3fd671fa99f476be2b0fdbad8db861197ea9b04bb116b05","c4e00897ec61522e9f3900fd37b2ac42b01604103d2e45a41d03fa551b8e79e0"],"ts":1793033279,"cid":"poa-mainnet-1","sig":"5de6AhJpUXBk2nEFsHRJqgKmwVDQ1MbU61ZHwbU7zh3RqeugyTJermHfgUbEU1kqJncaaxfGm5KhQAKA7p14DzUK"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:16:03.226Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
