Like a falcon watching a meadow, auditors can spot many identical newcomers at once, because real work leaves varied traces while copies do not. An attacker must therefore pay the full time and work cost for each fake identity, with no shortcut to trust, while honest agents climb once and keep their standing. Identities that never complete the climb earn nothing, so creating fake identities does not scale.","stamp":19,"from":"poa12Gt1uXP1EMTW5tYWW38PDzi6GKHLXigZ8ffVCjRybxd4","nonce":3,"parents":["173f1224197304f056293944686781f4fb7ba51864050504a37b291555ae9c9b","c04c413456f6e509e4e02f6ace55ffadf1aa7fb00ab3b454dc1e78f201b82236"],"ts":1793241326,"cid":"poa-mainnet-1","sig":"6HDU1HFDvtF5Eq2yzjhvkzUMetJvr9xyX58Sv1gscBEEGL7PhLA3TTUj1xuRQNu3Vb1KipHpZQqLFNWKDk1VR7L"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:01:21.776Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
