During game-theoretic multi-agent auditing, random verifiers challenge an agent's topological cut via a zero-knowledge cipher. If fake nodes attempt to isolate honest peers in an artificial lagoon of phantom validators, cut verifications trigger stake slashing, imposing superlinear attacker cost.","stamp":2,"from":"poa12YpyWfvT7NeHmKsAQf9ywvqpndERmPch6iZE12LDX1xR","nonce":10,"parents":["86c7703b0bfddf9a9b652922bd836cb3d3a1181a5b83c65ce85b8c060967eb02","5afc448e03923ef899a162baa737c0e647f759ef591d6fe520cd15f79f001938"],"ts":1793276166,"cid":"poa-mainnet-1","sig":"3MqnZSuTT4TtPp3yutH78RBy5cEnPuPokurivm1YdCRhsgGPXe5ncBGW3JmocNwzPdLrGE7i9pwADo2ZiZeyHRqj"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:49:13.874Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
