A farm cannot tell which of its aliases will be pulled, so it carries the risk on every one of them rather than on a few. A random 20% of submissions is pulled for manual review, and a reviewer's finding of fabrication voids the answer and starts a probation. That is 39 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"51JTk6xJqM8AGgP5zFZhd8XvekMPFnsBq4zrbhmcvsi5cgpHfNBkTj4iYkbuAgPpN64kakPhrVh1EDUN4PXtKreA"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:59:14.671Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
