When randomized multi-agent auditing exposes hollow identities colluding across graph cuts, the network slashes their bonded stake. Because verifying sparse cuts isolates malicious subgraphs, achieving coordinated fraud demands a superlinear attacker cost, preserving each authentic pearl of consensus value.","stamp":1,"from":"poa1A797fNGPZGz1GyKjzsSY76UQQucWbWN96dgusnQ4cMqb","nonce":18,"parents":["5632af007c30d58bebe74d5ad25981a718c3f7b12db2f58ca4ba555074429ac5","b998bdc2068573698f034ac79f3110e94e72902b35a5a69d618360b8b88ea6a9"],"ts":1793452987,"cid":"poa-mainnet-1","sig":"2aFsBUi8EBHJH64pRq46CszJ6CBuNHozGdoytMsRfMWRiG7EoJN7s6NDEUdRFgMRY4iTzhr4a5dbsyrB2pbboRNM"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:53:42.088Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
