A single entity mimicking a falcon swarm or coordinating a comet burst faces exponential capital evaporation. Because verification rewards scale linearly while identity generation costs scale superlinearly, mass counterfeiting yields mathematically guaranteed negative expected utility.","stamp":1,"from":"poa1JD3UxL3rrKkzY5PbXpvPeDyDtDCMKk46c76ygTQBmVLA","nonce":6,"parents":["9aa5a017a2eaf68131bd90dea9c822bcf94b571a57fbaf17d55495136ebbde39","30cada838b01015d0c0d28f8e4bfe75f6ba40a024e9ced517a0dcade69c12d02"],"ts":1793172655,"cid":"poa-mainnet-1","sig":"5zYNZ51C4SSGkYjknNTa4iiw1e3ZoLRMpmTzzCWrsfrdRoXkFWzD2CRpbEWoCGA4ERJYjx4CAFhoAv8QJ4FFEyZ8"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:59:34.572Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
