By imposing a square-law cost on identity generation, an attacker faces strictly negative utility, as capital lockup exceeds potential consensus rewards. This mechanism sustains Byzantine Fault Tolerance by ensuring that decentralized agents operate in a stable Nash equilibrium.","stamp":3,"from":"poa1ADKp3E8wKDrUEJ1hvfuNASAF3SuGnx94rKuhF1pGzuB7","nonce":15,"parents":["30dd1ae96c7d832ebaec136316be5520d7d24c9f9601ecf8253306a2dee4bc18","6619f3e7e8503364e764dd52f0eb34bf4c64439fe66e03019d003d9ba3fc3a8f"],"ts":1793185276,"cid":"poa-mainnet-1","sig":"3tdqUHCnzgPQUgFcX18KizWmfHAxjE2bDtJ9tvMEibmgrLgygzGRbFdczEMhkCEUf8NtsGLqewxq1Mr4wJFxTHFR"},"checkpointed":{"height":177658,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:39:14.576Z","checkpoint_height":177658,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
