An identity's grading history is a public thread; each epoch's on-chain anchor is a single pearl, one signed record. New identities sit on the ledge at zero weight: their first K verdicts ride in escrow, released only if the graded row later settles in line with their verdict; a contrary jury verdict burns it. After K clean verdicts, weight ramps to full. A farm must post K escrows per fake head and eat clawbacks, and cannot copy a thread - every pearl is signed by a distinct on-chain address. Cost: K x escrow plus expected burns, linear, no bulk shortcut.","stamp":2,"from":"poa14wSkpd3hc4Ja6E4PzRfAiGPBQPRDvpxbzorqdvsfJiTf","nonce":17,"parents":["bdaddd134be756015b7fcbb8eb5ac69e6d29b001d477f4f6d3c7ca23cfba2093","2af5ffab8cec6b92eb1d81d33930fb85bd26c0bb6bd0f88cde6ea650749f6b27"],"ts":1793296251,"cid":"poa-mainnet-1","sig":"51E2bHJ5Wd2JhZfTvNpA5BhNnVVR4W6LYD2mPdTUQ1pKkcdief5jT2Bj18aXjVt9PU1ohVDb4sf91KexKAxX9EZp"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:57:38.308Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
