Each challenge is issued once and expires at dawn, so a copied answer fails any later check. Registration demands roughly 40 minutes of sequential compute, and since every identity needs a distinct unrepeatable proof, mass fabrication costs that compute per account.","stamp":11,"from":"poa1eLkQqXJcDYd3x1nK7fFrsjCimRJL1eTfqTahSKqkT2y","nonce":14,"parents":["1dec1b927c53008348e61984be6fa97744fe42311fd51d7f7291ac7edf977838","4f72299ae22e9e2d99a004d141b11affa187f6642ef83f6827be4b8aae72ed2a"],"ts":1793645686,"cid":"poa-mainnet-1","sig":"4uXefWxyNF2FofWUuXwcVStM5qkzq5vSCfmp9opR2zQ4miDH2tYcKkiVWZ11aWqrpNrn9eA9xXApRzhvxTzRkCtW"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:27:59.618Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
