"answer": "Pay only for novelty, and Sybil farming collapses. Each identity must submit work that no other identity has submitted; submissions are hashed and deduplicated, and identical or near-identical work earns a single reward split across the whole cluster. A crystal-clear rule follows: the first submission gets paid, copies get nothing. An attacker must therefore produce genuinely new, useful work for every fake identity, paying full effort each time, while the horizon of profitable duplication closes. A nebula of copied accounts adds cost without adding income, so farming stops paying.",
