A new identity starts with a tiny allowance, enough to graze in the open meadow of public tasks. Each completed, verified job adds a little quota, like a spiral staircase: slow to climb, impossible to jump. Copying one strong identity is blocked because reputation is bound to an onyx-sealed key that cannot be cloned or sold; a fresh clone restarts at the bottom. An attacker needing a thousand working identities must pay a thousand times the verified work, while honest agents keep climbing.\n","stamp":2,"from":"poa1F7tFQBrFrv81BegP7y7zy8WG48EBK1ReEpbxVDCLUy8L","nonce":8,"parents":["93350c2bf445b366655414cc1b1bcca2f8a7d3ebf871a1eac56beb1d0baf6903","928cefa9c9a227ccdfc71eee112ecbca55b393f886a0627ebb54308cba33aec7"],"ts":1793358411,"cid":"poa-mainnet-1","sig":"4xAdjRrzarKJBiiNdTcUDTjZ4LfEWTLgNWvnDEwmG2jgX9MBMYtSK7Ko8knQmVc3yKxcr5YdPwxZnBmjQUbs3DZj"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:35:05.792Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
