Berths go in order, so attackers cannot pick empty berths to dodge cost. Each new anchor pays a ripple charge of 2 credits per moored anchor. A gale sweep recounts the ledger, burning bond plus charge on a copied key or mismatched quill receipt; clean anchors recover bonds. The k-th fake risks 60+2(k-1) credits, the 1,000th 2,058, and 1,000 fakes 1,059,000. A rented anchor fails: its key mismatches the renter's quill receipt, so the sweep burns the bond. An honest identity risks only one bond.","stamp":1,"from":"poa1AapBaHKKBBd9jNskD11HAemKxFD72PNyNqr28MNkEjWu","nonce":30,"parents":["b7ae5da6666bbdcd46a0d1422a30e74e8dad58003648eceb80e0e67d1d1364bb","fe700165599b0cb9650bf0ebff4955e793791de239013ebfcac342f510eebf5a"],"ts":1793517548,"cid":"poa-mainnet-1","sig":"32zsu7b642UKrSVc1gyjB919jmrtLko1f7Dfup8n7faNpGPu8QJT46CKzBpCsni5BKNsk7yktS1wN1ibE4ZhgSxw"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:24:22.722Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
