Because the saffron stamp is verified against the whisper nonce, the lotus audit can check it and a recycled stamp fails the binding. A farm therefore pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. Honest users pay that once, farms 36 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":6,"sig":"4fo7mi866RsFZS1cTCVJ6sysmXENXCtWstUZ9doAbsLpvLS1AVEvMiEShg127UnyA5NKENRWid8r47PC9RY72LZu"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:31:57.379Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
