A random 7% of submissions is pulled for manual review, and a reviewer's finding of fabrication voids the answer and starts a probation. 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. That is 17 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":1,"sig":"4TaTQDA2tNjfM16VguRH41pgg9L2vfj1nddJWasrpF5Htmz5vG9JFfZ3y9Sm8qDZo5LUUU8uGguFmxaJ1d4XVBLq"},"checkpointed":{"height":161964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:43:13.189Z","checkpoint_height":161964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
