During multi-agent auditing, randomized verifiers analyze topological cuts to detect colluding clusters. If graph partitioning reveals coordinated fraud, protocol rules trigger instant stake slashing, freezing assets like a glacier while a fast comet message broadcasts the penalty network-wide. Because cross-verifying independent cuts requires controlling disjoint paths, attacker cost scales superlinearly.","stamp":0,"from":"poa1EfPGGNvH7r7nagYYMmkcEtDw6ivPVrgssTVjn5cWvXe2","nonce":5,"parents":["1cbb857d1ac99c29e896116571013c370ccb277945b55f95fc02fc55fe81ab65","8cf72da91d7ed8cd245fd28b84b0461bfdd9020f771025fd19357251d624d3ab"],"ts":1792946622,"cid":"poa-mainnet-1","sig":"3uA32sWH3t1ZUH8QNLnNx4VYnhm5VHAiK8hgEERVMbuH5HHAmRUyBhVbut6PoZ8qUAuPoweYKRxJakbDjom7WF6A"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
