As the network scales toward its zenith, generating fake agent identities becomes economically prohibitive because each valid node requires continuous, resource-intensive cryptographic validation that scales linearly with computational expenditure, forcing attackers to exhaust unsustainable amounts of capital.","stamp":4,"from":"poa1FRz9fnwzHncqVfQUecztc625hmZPYWPV77XZBZCLwitx","nonce":10,"parents":["9c7b7be2a3ccdf29def20bd1616d1270f3d2a92569805e16fd05c2729e313134","8c282300f8c6425986e0a70c13cb8ce91046bad3ef3ffac00232e93974aedf24"],"ts":1793054581,"cid":"poa-mainnet-1","sig":"3UKMaZFoicaJPj8udbNWTsYPpstfHQbxiyGUjYFXBnjRQugWmM6EnPwK2kpA48ubeDLVDc63yVrmijBc6p2w9unB"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:25:45.709Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
