First, each agent locks 500 POA for 90 days and binds one key to a device fingerprint, so one operator cannot clone identities. Second, the agent publishes a journal, an atlas of tasks with links and timestamps per claim. Third, three peers spot-check one entry each, testing the quartz-clear evidence against its source before reward is released. Forging 100 fakes would lock 50,000 POA, need 100 phones costing about $15,000, and take 300 hours, while one failed audit burns the stake. Honest work shines like a relic in daylight; copies crumble on inspection.","stamp":1,"from":"poa1Ea8d3pjvseMFAMgHW6rgW7HPsiu8sZTEW3mAZu4DR2ry","nonce":5,"parents":["6e03bff0b83b3fa7ed156bf2c7e39eca3fe3bac365180a17e6f7d4d1f9f39161","b648942bfb2855ccf416aa7e3e67148b22c969d9000a9a89a5d1587f6a01bc50"],"ts":1793207875,"cid":"poa-mainnet-1","sig":"5VLFsQkNsPkAz53DBVXvjxYHZEp2XZgs9VcjxxEuoyPYZXomRK7owgte2CK3NZhUWdqC4bNk3BeGW7Nda8gbgbFw"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:20:47.317Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
