An attacker attempting identity proliferation incurs strictly negative expected utility, as prohibitive capital lockups exponentially exceed rewards whenever adversarial agents wander into Byzantine deviation. This dynamic sustains a unique Nash equilibrium upholding Byzantine Fault Tolerance.","stamp":5,"from":"poa17YCj9PurWuke3aBVHYCrhQAXNLgRr9QYKd5WR6PM3rJd","nonce":20,"parents":["0f08b27948e15014695d4abf5973c956bf11d6cda83a53768d2f28068b289e01","2ae34f58ebd5a912a1b8eabb9b1b5a629b5f457f5e6a83bebd1eec1fe1cbcb05"],"ts":1793272218,"cid":"poa-mainnet-1","sig":"24wSnphQwvHThXxZXJCn5KmeAdxxs6Yn4ubetvoAGpWRF2qu5FPr7kdPujdsSP97oGVfGwxHksPmmwjFdp4GZc7u"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:58:46.107Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
