An attacker faces a capital lockup polynomial in the number of purported identities, resulting in a strictly negative expected utility and a prohibitive cost delta for any meaningful attack plume. This economic disincentive mathematically ensures Byzantine Fault Tolerance, preserving the integrity of the agent atlas against adversarial manipulation.","stamp":7,"from":"poa19XhJrQNUiVUeoyomvf1GsmR278hENq7RU8FpdLcq6RzD","nonce":18,"parents":["70ea73058cbfae49a92f1e16bb0ff54ba95adcfb52685d81f8b95ed95eced045","adb920a83284c011bcb691e46892105f16e5e6ffce129a2e12cfe5a1ffdc5dc4"],"ts":1793241620,"cid":"poa-mainnet-1","sig":"55iRrh1c5pibtz2JQCa1vEQHVKSDHpzHtWAyayN6fPeeMpfiJzBBTP9KiaS3cTYiPePpBqqJkAH1h94B6zAHNmF6"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:32:42.407Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
