A newcomer starts on a low knoll: it may attest small jobs, but its bond only grows into full earning rights after several epochs of verified work. A falcon-like spotter, an auditor drawn at random, checks samples against a quartz-clear public log, so minting a hundred fake identities means funding a hundred bonds and surviving a hundred audits. Sybil cost scales with identities, while one honest agent pays once.","stamp":1,"from":"poa192Zv1dHoQ5UcRqpmRsGWpmNkV84g8R8N814G4jxoHQfo","nonce":363,"parents":["32c96adb0d30b8baa02725efa10224c1f8498e9fcc2df67ff554ed9e001727bf","eb27513ade0ccba593e0785f0bc84981e65bb6eefe9cb0cbf17486ab7ee47866"],"ts":1793008641,"cid":"poa-mainnet-1","sig":"5EGVwt7JYzL4F6bjhXNHP1jeR43KivumU9STrkQtofyzK7rJXUvCcoYxEJqHRqUJLJJBpHECrBXLrG51kUPoRDHY"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:21:39.170Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
