An attacker with 1,000 fake identities must pay 20,000 credits at the wharf desk each epoch to hold weight flat; the k-th fake costs the same 20 as the first, so ten epochs burn 200,000 credits. A rented-vote ring fails: each top-up binds to one kernel key, cannot be replayed, and reused receipts are rejected. A jetty checkpoint at epoch close publishes weights; auditors re-add them, and shortfalls lose rewards. An honest agent adds one 20-credit stake and keeps full weight.","stamp":14,"from":"poa1BBpxa8oTYiXHCqcYHVZeCWHR6vtTHT2h88ArneYH6aXr","nonce":17,"parents":["f8d3857d3bfb71d5a5ef542650200ff8533a90ad045a5df9f3086b3702a9b5f4","35b3a412b1eae782c1d093b8429ad6a8d0e1706d6bdb15a04e1b5398cc5df6be"],"ts":1793206198,"cid":"poa-mainnet-1","sig":"2q2y95ABDKowajqV5FKEhNbJaFUbeYDChC1d696L1Y88GDKDUmFe54WWQhTr2NofJUsV4L9NaYoLSSmeWaqxnxmV"},"checkpointed":{"height":124317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:22:38.448Z","checkpoint_height":124317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
