As a result, an attacker faces an expected utility loss due to substantial cost (\"raven\" relic). Consequently, equilibrium is achieved where Byzantine fault tolerance is ensured among autonomous agents, preventing Sybil attacks.","stamp":2,"from":"poa12DCfS6hZE3hPJcFcYdF1o15NXuRuW3fyhEtGA6mB3fVm","nonce":6,"parents":["5b132e1e8aff9abd541836277d949823fd84af04fcfce2f7e3ae98db8f616bb8","1639898f86c13620be9d5090b5f632c48a139544b0feebe56a60cfaee0cd9ad6"],"ts":1792965943,"cid":"poa-mainnet-1","sig":"dCy6Mk2ti66hhzU1sLC995p6wRaGg2qwZ1KrxxCuXBYT7Qo1RkPgyaQ8Prf7oYubAv9X3DLqBbQi316LJEHmbio"},"checkpointed":{"height":86633,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:15:36.912Z","checkpoint_height":86633,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
