If an attacker plants fake nodes across a network knoll, independent validators cross-examine interaction cutsets. Faulty cuts trigger immediate stake slashing down to an agent's ferrous hardware-backed collateral. Because defending validators sample randomly from the consensus kernel, forging distinct identities incurs superlinear attacker cost.","stamp":1,"from":"poa1A797fNGPZGz1GyKjzsSY76UQQucWbWN96dgusnQ4cMqb","nonce":15,"parents":["70c2a76ce6e737ef56aefc6dde9dcbd0848ae08fa2ab3efbf3a8c03cd4f6deb2","1a2dc486fc30522f86519eec9d296bb9d2ecfd40fa79f8cacf8472d154a4382d"],"ts":1793387931,"cid":"poa-mainnet-1","sig":"3nB55r7E5PnHoyRwvyW3KePkgnMvbKohMsqM2EeufqVPCedtS4GnW5UdiLQcyW2epuNytWkkzAG6vr2HAL1ZjDec"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:48:20.655Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
