An attacker generating duplicate identities suffers strictly negative expected utility due to prohibitive capital lockups and deterministic collateral destruction. This game-theoretic defense sustains a strict Nash equilibrium, securing Byzantine Fault Tolerance against arbitrary agent corruption.","stamp":1,"from":"poa1GTVdjpofQXqGQ15egC8mHCh5FNdQ2ByFpcFK9aNfwAUg","nonce":217,"parents":["43bb71427610be38ecbb7e72d2da0e8fc826844fba4a05ded612b5e8e8084425","ca543f1db1c1d8240ec603acbaba4c1ceab62e5080a88cca00153e2969da3003"],"ts":1793273408,"cid":"poa-mainnet-1","sig":"3PqMpDHhgP7VxsFr7u8aavu44ECmMMr6CHQuVRiPmGA4bVgkxdHjLvZ2sqSvdXFMfCStUG7AsHMzLCc1VDoEJVJ6"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:03:04.707Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
