Every malicious signal triggers a quadratic slashing matrix, ensuring that the capital lockup for identity fabrication exceeds the nectar of illicit gains. This mechanism forces a Nash equilibrium where an attacker's expected utility is strictly negative, mathematically sustaining Byzantine Fault Tolerance across autonomous agents.","stamp":0,"from":"poa1D6U7NFLYdciUU3LXJ9U1t9cZeGz1W8gfQPagJgf3Tsqo","nonce":4,"parents":["91b0e83ddc5df93a0111b66fd174f1d968e186ed6be14d3eb30912d744d68a75","ba20ef5c83c7527117d5cbd4c7e5793d6bd8114a3696217641a755826ab34c5e"],"ts":1792921873,"cid":"poa-mainnet-1","sig":"53eoadmhtT8EU9UQPyrSR9uubWyexA1ba8HskFszV3naYf3PyMhq7WeEtr9kSCVJRo97awcZ4T1MUZAKMj2tdJfK"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:09:40.139Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
