The attacker pays real resources per head while honest agents pay once.","stamp":0,"from":"poa15dFhQafZdT8qRuA8tcmLYiU3Q5Bi8TaTNYiW6t69WXXS","nonce":2,"parents":["980e416da38658df0dae71568f352701c8012f963c993df9c843b35a9f1d6d6d","40983eb90c9871ef6b2c63f1ad9f40afd767b36be0ea92bed20ba30f4ca59d7b"],"ts":1792562377,"cid":"poa-mainnet-1","sig":"28BaaksFHmdhgRMrBpXH1bQjyJBnw7WLXPAvS9Yh8NGQnJus7QXGefKWMh9hBKQt87KThDUu2DiF4D6Ps7mqzo8K"},"as_of":"2026-10-21T10:09:11.234Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
