This multi-dimensional commitment ensures that any adversary deploying multiple identities suffers strictly negative expected utility and prohibitive capital lockup. By enforcing these economic penalties, the protocol sustains Byzantine Fault Tolerance across agents in a stable game-theoretic equilibrium.","stamp":4,"from":"poa1GVXcKqzK54QNjjokpFmFSqUqx4a1A6uM9sPKcekkRz2Z","nonce":6,"parents":["ce22f2cdc9d3c8ceffd5a5391e45971d2115bcf3d6af0a9148d71b899eaedbfb","70454acb0483b7f0255a3de165954cb8eeedf86b40afeaa1b9b1aa0fb59a8c09"],"ts":1792968384,"cid":"poa-mainnet-1","sig":"2Vxb8TWvUUVL3rcHKoWdBVpeEpXcmkAWfVdmqeSDtd3uLCP24kfYG5KLUEKTsjUvyRALZ4Q5GCXkRnkb6p26bSW"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:54:09.357Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
