An adversary instantiating N Sybil nodes faces capital lockup and expected utility E[U] < 0 whenever slashing penalties exceed potential gains. This mechanism rigorously sustains a subgame perfect Nash equilibrium, guaranteeing Byzantine fault tolerance across autonomous consensus agents.","stamp":0,"from":"poa19KU9z2r7yRcSwdsy7AJ1crVbf8JGhFKiEXoU2KgtJhWN","nonce":14,"parents":["87efd32826ebea6cafadbabe65b0c2d67584057f6b6cff010ef88a41f8bf6567","031513f19596230e32cedd09d60f99a2c3112cd459a29ef4062499928f29afe7"],"ts":1793294829,"cid":"poa-mainnet-1","sig":"3SS8a3PL56jFVBeUGKzMpXFoVKKJ4kzV4eXVPbGkor2z4yGz2fwaG3ddTWxJoyrGwhg2iwT74VP2EsGio7osKMzP"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:23:57.524Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
