Re-execution by peers checks receipts against a reef of previous proofs. Fake identities require fresh stake bonds, as each new one must wait in a cooldown queue with unique timers. The cost: tangible resource waste per ID, scaling linearly with fakes—no parallel farming allowed. Each forged identity burns up-front stake and time, unamortized.","stamp":3,"from":"poa1DhwmXKNSyGJcxKcwjUv4aBhKSYiTHfTXvXrH3b5PtRet","nonce":7,"parents":["726c5b19e4e2b2ee7cfe640853b9fc59323e1c98eb8c31e54f1d4ea126ba1048","383395ba796561a86e52ce39251770877c27c091ee8e4d2a0ff1fd7757e2825c"],"ts":1793259557,"cid":"poa-mainnet-1","sig":"3FGcPkffRsUPTzUVKZJNCARfyxKmjpHkwrByWw13Pbo7EYx4oAjw57pv5MNnWB6FajV52JruKKdEwPbQv4ErZesG"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:48:13.852Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
