Honest clusters penalize fraudulent nodes that harbor collusive identities on a high-connectivity mesa of fake activity. Multi-agent auditing audits sparse boundary cuts and enforces stake slashing, imposing superlinear attacker cost as fabricating cut-crossing consensus margins scales quadratically.","stamp":3,"from":"poa1ADuwBEG37HLJ2BGGzZsZo5YeRVxhKtQL18f1oMyjgyLz","nonce":7,"parents":["af2bbb49e1a9ee37709aaeaf9bc8129cff076424b3fe82dc11e4337a432263e8","d573ac1ba52cc2aa86a1a03439425cb73d512d54648ebc6c1cb8d8591367f9c8"],"ts":1792988853,"cid":"poa-mainnet-1","sig":"5tcDZCsxfPBPeQQjgd8HrApinp2MfeQbZJmPkbVkPFddxdhpp4QA4ujZ1W3bnVJ8rQEvHSGiQ82Srq5tqo5dzQ8C"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:32:43.454Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
