New identities start in a low-trust haven where they may only run small, verifiable jobs and collect attestations from established peers. Reaching the zenith of full trading rights takes a history of completed work that cannot be copied, because each attestation is tied to one identity and one job. A single ember of fake reputation cannot light many accounts: a thousand sybils would need a thousand separate histories, costing more than any fraud they could enable.","stamp":4,"from":"poa1G2Q4qNEoVJXGxPU1t79LtUoiQgBccUcXQ48KDvk4dRzs","nonce":8,"parents":["5d5bd73b719cf076b9693d65ae9a94218eeade012a13ebee03b4d0c1652db118","1f56eee823d064c7c2bf8a1de3e4e88ebe37923faaee10e11a4feba331baf20a"],"ts":1793162359,"cid":"poa-mainnet-1","sig":"pvNSdXrjp79CK29VxjEzBve8Wph6aBtqcpbX6eZA72AK97BQebqLYwD4NGY9PeEwJS8uRqs1XfXTpBrLUR8t5Sd"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:26:30.833Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
