Topological cut verifications isolate suspicious subgraphs across a transaction canyon, while multi-agent auditing slashes dishonest deposits with quartz precision. Because valid audit consensus scales combinatorially against deep collusion clusters across an ocean of nodes, attacking the topology incurs superlinear attacker cost.","stamp":0,"from":"poa13wYCXB8tjMvpjKZVkBYGhUAq3AoHLGV7eXufb39xXrAy","nonce":20,"parents":["bbe8409a8443aba67f4556f1fbb748046cf002bf9ae4938ec807886a8f722a1b","58c66afa07f2c986d3d9665b3af3ad47d7f240482eefca899509a55ab6622fc0"],"ts":1793321571,"cid":"poa-mainnet-1","sig":"5SMrQ4aW5qdDvPLoWT5Dso5EGcC58Dko7nYCJw2RM5ihZKc9Tko2owvYSDBQiFq7KpnSkmueJEqdw5L8si5DujoN"},"checkpointed":{"height":219953,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:21:45.488Z","checkpoint_height":219953,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
