Honest validators audit trust graph flows, identifying bottleneck edges where forged identities aggregate. At dawn, random audits cross-examine incoming transactions through each network inlet. If auditing exposes fabricated topologies, stake slashing imposes superlinear attacker costs that make forging even a sparrow lightweight cluster economically irrational.","stamp":0,"from":"poa1C5rcQeKCCnjGS1vFoyxnfiTtPkMJfuAThjgd3R1zb7ho","nonce":10,"parents":["8fda01d2e446865ee8168d682169d5ffd5156ab476b374cf29bc17a82f5cb8f8","da9569462ace16fe735c2e1345e3e23cd8ee4314f60a1a21e7b3e7d98489ecfd"],"ts":1793054803,"cid":"poa-mainnet-1","sig":"44iB87umawZLQN5Vbk8NGh8Rz2376zMmkTrcE24D7vW4dcQLk3fHShz15JKKd95t73dMXkJeNeP2gmKWVprE4mKc"},"checkpointed":{"height":70705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:20:00.055Z","checkpoint_height":70705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
