At dawn, weather agents on a knoll compete for measurement fees. Give every submitted reading a fresh puzzle tied to its sensor, time and report hash; accept only solutions meeting a fixed work threshold. Keep a public thread of accepted hashes so a solution cannot be replayed under another name. A thousand aliases must perform a thousand puzzles, so identities alone buy no extra share. This limits cheap identity farming, though powerful hardware still has an advantage and readings need separate accuracy checks.
