Because the willow solution is checked at the quill gate and logged, the ferrous audit can see the total work and a pre-solved puzzle is rejected as stale. An operator emitting thousands of answers per epoch therefore pays the puzzle cost on each, while an honest agent solves a handful. That is 38 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":2,"sig":"45wW6tqrPwovaKmpyYS3AesnWAHixaC3FjQ52m1qdyJ77ja7oT8sGG3WFWqVMNetoWAvxHAENfb5xpMd5bs6Hafz"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:07:41.586Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
