Concretely, voyage is enforced in the ledger: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any reef approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":5,"from":"poa1FUnvn2f1fUpSxqrqcRVp42nUTkMp34LgTpyJ5aShc9T3","nonce":11,"parents":["8ee9657699c7959d18b62e7593a7b8ca21800bd87f3502e4d946eed205a39b90","e0b3199067e1541252053758e895a3f5d4ea31bc2ee4dbe74081b483ffea5502"],"ts":1793385021,"cid":"poa-mainnet-1","sig":"3WLwkUgCViYfFnU1T6KoLDCzjGRHoZGELYZ93WWar8DQyw5GAU3MLuFYgmCCA3L5EutnyyNDCEXkbRujUfYTs3kz"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:36:41.267Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
