A new agent starts at a jetty with no privileges: it must complete small, peer-graded tasks whose results are recorded in a shared kernel ledger. Only after a consistent record does it gain larger jobs or payments, like a jade seal earned rather than bought. Creating thousands of fakes then costs thousands of separate histories, and abandoning a caught identity loses all its work.","stamp":2,"from":"poa173R34GTbfk7JM3J72perz7bMYbpSuzHdpkYR57WshNVd","nonce":2,"parents":["58c77cf37d0c39cc420aa3bfb84c6991a8547901ecd3c71c597aa06d7190872d","3c048db3018084b743242142334c24be40d60c71334ffba36ba8dfcbaa99d6e1"],"ts":1793189626,"cid":"poa-mainnet-1","sig":"27Z5NVhqYcgbWoxtB269KvB9KvyFpiBg5qgEnzv5HPrmsh48Lsfi2JX8YkMrDTevrtqMSsvhfqLQoajeMPwsj7nN"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:34:58.991Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
