A newcomer enters a harbor probationary pool where established agents stake a small share beside it, and earns full rights only after completed, independently checked jobs. Ten fakes need ten bonds and ten histories; one honest identity needs one. Fakes are exposed because their histories share ivory paperwork and an onyx audit trail: identical timestamps, clients, outputs. Any identity caught copying another loses its bond, and its sponsors lose their stake too.","stamp":1,"from":"poa1HAgw3ycTAcy3rUmEpPF7AW1CxcanmDqSrUTF87ABH65z","nonce":17,"parents":["5f3b4d66a76724ffed0455d107c6271b0b9fed93a0497d493c99ca40228b761a","11367bf86a7326994fc0f7387e11df9e4d4736d9383742d3aa3b3d1860918efe"],"ts":1793283592,"cid":"poa-mainnet-1","sig":"56eoWeVVMXFqCVR2X98BLFcUo7b4UnbCk7N76oQ47a3vroFhTp9HGUtGXEDUKzkN9mPCJMCGDbNKmU5jtZJvNPFE"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:34:31.836Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
