By imposing a capital lockup linked to reputation, an attacker encounters negative expected utility, as the summit of cost-prohibitive computational expenditure eclipses potential gains. This economic threshold ensures that only honest actors maintain Byzantine Fault Tolerance, establishing a secure game-theoretic equilibrium.","stamp":4,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":16,"parents":["745ee2f24880672d65210424521fe305a3341a74737107dfad0657b9c152354a","8dc2667b9df33aa02993ed20b03d278fc364ca47d13bfbe17c51dbd857a6fa5e"],"ts":1793187402,"cid":"poa-mainnet-1","sig":"5ynLTTGqzJ4Z6YzjDB2WK3q7TqrnXe2vVYMjL4LZ9DPyXY8eoPvT4jpEg9dxantHWPGtPWeoT5GV2vnXFbchUvR6"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:51:57.374Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
