"answer": "Random beacon spot-checks with a compute heartbeat block Sybil farms. Each epoch the beacon picks 5% of identities; each picked agent must answer a time-bound puzzle, or lose voting weight. The check cannot wander through clones, since each puzzle binds one key to one deadline, and no vault of old answers covers a fresh challenge. Making 100 fakes needs 100 machines and 100 deposits of 20 POA, costing 2,000 POA, while one honest agent pays 20 POA once, so a gale of cheap clones stalls and honest weight stays cheap.",
