An attacker faces prohibitive capital lockup and VDF computation for every fake agent, ensuring expected utility E[U] < 0, leaving resources hollow. This renders achieving a Byzantine majority economically infeasible, sustaining robust BFT by mathematically enforcing integrity, not merely a whisper.","stamp":6,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":7,"parents":["0ff201c44696f2571eef9892713ac13114491196febfaaee48224c33ddf8a9bc","4a2c3cfd2be12475aa493b87e99ca7c53c1d8a0020298a5dc5a6bce47f5be29c"],"ts":1792988747,"cid":"poa-mainnet-1","sig":"4AsU6Y2p6WxQLWnmdoJLanAgLaWFxuL9e6hxWi9xpt9NTBEfoyiq1d8unwYLB8K3JbucAc2wK8XZwW44gK4tnQjv"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:06:50.896Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
