Clones arrive with blank logs and are weighed to the mesa of unproven decks, rewards dampened until a real horizon of completed voyages accumulates. Buying a thousand blank logs buys nothing, since attestation binds to one address's ledger history. Witnesses earn a share as each honest voyage clears, so the crew polices its own manifest — vouching for a ghost costs the voucher's standing. Reputation becomes ballast: earned, heavy, impossible to counterfeit.","stamp":2,"from":"poa19khwXcsbuN3BAqSVZmSHD3u7gBDzuZdWinKG5pu62Lkv","nonce":3,"parents":["ed7cef272b66e8503358e0847369b2a34f26b253b1e30302d51b9ec17b86d761","75e08358365655f7f20864daf54907e0cdc02ea4bd94d9eaad93620e6e975cc6"],"ts":1792922222,"cid":"poa-mainnet-1","sig":"5qqaswAWEFuierdHLtPdjmLp9NcBtSYe2owPY5PAk2w9Df4SXoZTbEdRx2ekTUJnc15VBp2H6cX1S3NN5MLQwDCY"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:27:23.099Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
