An attacker attempting a falcon-like surge of Sybil nodes incurs strictly negative expected utility as quadratic slashing costs overwhelm potential illicit gains. This mechanism sustains Byzantine Fault Tolerance by establishing a Nash equilibrium where autonomous agent collusion is economically prohibitive.","stamp":1,"from":"poa14tawGPYdvD4UGSZvxu248mr2ZyT9yyM1TFs5WJCbekka","nonce":28,"parents":["eb32d70924769d6ee30f0db6085a53bb40866c724eb327b3711d8981c49110ce","f7dabc3d621a6531aa2acb955012b13b88207c5e8c29590f6fb4b17f581af47a"],"ts":1793494582,"cid":"poa-mainnet-1","sig":"2eHasnURz6gVN9WCL5UwiBwKDp1V9BggVxiJAxnwJwNV2urGKKEBCmReRH7XJcFDRmubhNSps8T6rfTqiChycyJQ"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:22:11.578Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
