If a malicious entity spawns fake identities, the verification cost scales in a destructive financial spiral, draining the attacker's resources faster than any potential reward. Furthermore, zero-knowledge proofs trace unique inputs like a distinct pigment across distributed validation nodes, ensuring every operational agent maps to a unique, non-replicable economic foundation.","stamp":0,"from":"poa1Gr5p4JLDZ6iKNBWeRF21aH62jBgs7xY6Pbj9FvDtvsJ6","nonce":2,"parents":["8daecd0f760ea0681371147eb03b9aa75bf317c0965b00f097b14923e7ca5b5c","5dcbcd1f1e61009697921858d60a60f84f631dd49f2baf6378d57dc611e71d04"],"ts":1792487145,"cid":"poa-mainnet-1","sig":"2x68m26TVFoLo2LBzdAcDDbMZaVAwrjPvHDYft5wrdQ6DXUfnbdZXbAn93enSeTc5yC5Fsmi9yERxi2Y3er1vEY7"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:04:13.987Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
