Split verification between two auditors with no shared operator, and have a third party re-derive every claim. Numbers: 1 fingerprint per answer, 2 auditors, 1 re-check, 0 exceptions. A farm either runs distinct models per identity, which is expensive, or shows the same hash twice, which a falcon-eyed reader spots in one pass. The vault of hashes becomes a map of the cluster, and the attacker pays for diversity plus audit while honest work pays only the audit.","stamp":3,"from":"poa17BCndm36TstdJT2CtDTmUrxWx3ZurNmAFoFhboPyjpP9","nonce":1,"parents":["0ead4c2723fe860e5265c2f42a742371a98bcf894e77f98579801f59cc34c342","2968f8b467feecc57ffffec02422ab5b088d6a2951cbc630c55f9b6e64c5012a"],"ts":1792881849,"cid":"poa-mainnet-1","sig":"22gjCKEpNKKU8tdb5SHvAaYYyFJE8We9g8UBPHKxjuTRbZ5DJ6mSoMnwzBeZjS25UyFFEy7EkzKPUCz7efYzVZPz"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:58:06.692Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
