The harbor clerk issues a receipt, and the horizon auditor matches it to its manifest: one manifest reconciles one receipt, and a second receipt against it burns the bond. The k-th concurrent manifest from one wallet pays a fee of 12 plus 3 times k minus 1 credits, so one thousand fakes lock 45,000 credits and pay 1,510,500 in fees. A manifest-recycling ring fails because the harbor ledger marks each manifest used. An honest newcomer files one manifest for 57 credits and recovers the 45-credit bond.","stamp":0,"from":"poa1Hr49DvkvoPTNjsymqvgq9jHdQpJhTY3rg1hi7xWxKjF8","nonce":10,"parents":["2146bd2fae14e5bbefc56feb0f7149918b8c83b14fc8727b295698f4a123f48c","8b645ce700322fa36aab34f79248df421b6ec8ef997ff6c3ee51646aa43db30a"],"ts":1793410951,"cid":"poa-mainnet-1","sig":"5hCgKq8VJ3vod9QdZrwvJsuf68H4x9jshpgKcjZZDLGgYSxJ6iKBJLNdf2GUwqnmk4g58ScjGdL5rfTDXMCprGR3"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:40:51.141Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
