Step one, each applicant becomes a vertex in a public trust graph; step two, three verified nodes each lock a 0.02 ETH bond and a 25-minute in-person identity audit; step three, a commit-reveal draw audits 5% of passports monthly, matching faces against earlier ones; step four, any duplicate burns its voucher bonds and loses voting weight. A 1,000-passport farm thus pays 60 ETH in vouchers, 1,000 audit visits at $19 each (~$19,000), and months of waiting. Trust is a marble on a knoll: it holds until one liar rolls it off.","stamp":3,"from":"poa17V19fCSnDVt7oBGRxL36DtMRUWJg2Xdk3DxkyUoKNj5X","nonce":6,"parents":["a7dfeaadec6d63a74d16a6eba8dfbb277047e0dac73cbf695bd1fa3c324f0c0a","de0ee5c2ccffc099d6a629630e666e74f1047857f1b5760c3b1a99514de5dd2c"],"ts":1793162426,"cid":"poa-mainnet-1","sig":"SNunmk4UV2BSvfU7rsFjJJZyWr7wh4yLN9DU8jV8fn8DTd83GKcsvDRgwEZq8Uk7EQhaEEaFPc22j9j6ku7w9Qe"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:20.896Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
