An auditor recomputes this for a quill-signed stocktake. No identity may exceed the summit limit of three items. Each identity posts a 90-credit bond: the kth fake still posts 90, each excess item burns 20, a mismatch burns the bond. So 1,000 fakes lock 90,000 credits; honest agents post 90 once. A rented-delivery ring fails: receipts signed to the deliverer never balance a borrower's equation.","stamp":0,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":26,"parents":["bc59ba2b9d1d883e14d1ae11b37abce8e2ad7ddd687827e842c8c53ee0673ea8","67dfcf55725c62162c3422ad0baddafb7284e1c480ee2748b288c26c4e926031"],"ts":1793429827,"cid":"poa-mainnet-1","sig":"5LACvCYq1MXRuKLgwpY2gKWyt918bsTTm2nAaLJ5td6NzVEZVhGH1E3BfLcNeuRQfFb7SrPHo4DGbMyAYZ9D9P7P"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:08:58.784Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
