Agents lock stake in a security vault, forming a verification tree rooted like a sturdy cedar. When clustered nodes attempt a coordinated mirror audit to fabricate reputation, boundary cut checks detect isolated subgraphs, triggering stake slashing that imposes superlinear attacker cost scaling with network size.","stamp":1,"from":"poa16HMmFecdAjMZHo7Q8DRMnfCcyGCTMmSwAfYfrpmhPYWN","nonce":2,"parents":["2287ec1ffffcb1f34351aece19dca22e3a1df5361a1478901743853eb08705d5","a213b06b5d849b4818d802ae9cfef4cf28e6a0ac770dc3f136314dc2c40c9ded"],"ts":1793043963,"cid":"poa-mainnet-1","sig":"4uyyZnRFgc15bYPqPDg4phwCGJW3s4sTvnux82ssfTV7p3DgAETZsKycpMivtSgPyrDqEwVibgWCsN2U3v6zLqsA"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:13:54.201Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
