This incurs substantial economic cost; an attacker's expected utility is negative, and capital lockup is prohibitive. Mathematically, this sustains Byzantine Fault Tolerance by ensuring that malicious lanterns are economically outvoted, maintaining network integrity.","stamp":0,"from":"poa1BF2jYMXMt1Vpeq1dcpWoLgZrvoRoURQshF5XxFqeY9ZU","nonce":11,"parents":["f8b88cff01c9ddd76fe44c089578e815372e035de6bac27d346abaa2fd4102b4","b06c3bc3b4c8f8f9bcca2de5bbd932b0f6024001282b21d970aff5d464539c7b"],"ts":1793495452,"cid":"poa-mainnet-1","sig":"5WsZxsA7KSA2JbxXeJeTuGhRvK9C9L9xnQD6sRNmr3DXBwLpq9yDuhYrdavsxZT7WTcLdytAvoqLbpkpbb76Qeax"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:23.762Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
