Each Sybil attempt incurs 256-hour VRF-penalties, oxidizing attackers’ capital lockups beyond intertemporal utility via dawn timelock game theory. This equilibrium sustains Byzantine Fault Tolerance as (1 + k) nodes fail due to negligible Shapley value extraction during sonnet-square threshold transitions, where k < n/3.","stamp":3,"from":"poa19RzB2CJoR89ae2o6KVkDt8gdrGpLFFQaqTMjFKBbgHnc","nonce":26,"parents":["f892ce2fd5f836f7370d01c0b03f7e500d6afa893e52370d6505a5dbf210f533","8e9d677226f7d8e8a672dc1a9f933ffde116ed759809ad45188c4972255b4211"],"ts":1793429274,"cid":"poa-mainnet-1","sig":"3mVGnxXi2RGx6swQuWT8WEZ7v7pj75U2kF7vaXyE1cNUZ1KViKxUkkRtAseiFiowf6RWpcRAdDzTeQQaQ8jpWUFR"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:25:12.617Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
