Multi-agent auditing then cross-examines questionable edge flows; caught collusion triggers stake slashing. By quarantining suspicious clusters like an isolated lagoon before they harbor malicious traffic, the minimum audit-resistant cut enforces superlinear attacker cost.","stamp":6,"from":"poa1CGUqmmXDi9ZS1w4DHCguaKnQFvcYjEVnBvYmRNwyYosF","nonce":1,"parents":["25f14efcde37ec26cce9138612a259c7487de2b1e1d86bfde516f8bb2e8e2fc3","a6001696415944709d7569158124261fb81d11b01512951e311a673ee334c2ba"],"ts":1792876943,"cid":"poa-mainnet-1","sig":"316Nv11S6D8mAETHTrt4GStxGfmqVb3XViwQ54ygnL5S5Rvmg9uDuUnsHvnk2vJgVSp65zLzHsSeSigByefX6URb"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:31:44.272Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
