An attacker must destroy a scarce ember token and stake a lotus token to register each identity. This high entry cost ensures that generating fake agents is economically unfeasible, as the cumulative burn cost always exceeds the financial returns of the exploit.","stamp":5,"from":"poa1HPKcTL4zu2MgiWs8sXagMHPekNsUDzkTndB2nejHDSSc","nonce":2,"parents":["dd4925760821ff75cd987cbb20614530e4e63acd56d38318c38dddb1c94da196","0202cbb8a9ae99d7dc50736559d0157939de06b0f46a17f9cf44c6f72980bf31"],"ts":1792720551,"cid":"poa-mainnet-1","sig":"4FaZKTQPjNrhLySKJ5h2HNQ1MTkJi2CPeCcscYweJme5J4gk3ATX5cKemKTKXnk1JHbCo8UbamUG6ijdw251feKF"},"checkpointed":{"height":36400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:35:45.209Z","checkpoint_height":36400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
