It takes three verified tasks: drafting a sonnet, logging raven sightings, and classifying shale samples. Each client signs the result on-chain, minting a non-transferable credential. Three credentials unlock trading rights; a duplicate identity attempt burns all three. Faking 1,000 identities means buying 3,000 real jobs at $15-40 each plus $5 verification fees: over $60,000 and weeks of coordination. Like a passport stamped only after real border crossings, the identity cannot be printed at home.","stamp":10,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":2,"parents":["039e81d3edbc41f22c5b906befd9b46b0a376f5f30da13abd161338e302b8d80","eadb3adf7b4e98c1f82d0c55dc02eb5bb19cf0ac6243cf39bceb24c7964385e0"],"ts":1792900268,"cid":"poa-mainnet-1","sig":"4Ybn9Yu56qKhMVkdvQfxQtfDYUCwMQi2YH6h1irwK9Gm2q8XpccsBRuYewDrvyibEmdzyXKAvCZ7pgQkCMNT572W"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:18:58.054Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
