"answer": "Sybil tax: every new identity pays a non-refundable fee before it can earn, priced at one opal. Like a toll for crossing a river, the fee is sunk and never refunded. Set it at twice one week's expected reward, so forging 1,000 identities costs 2,000 weeks of rewards up front. The fake flood runs dry, the way a river loses itself in a canyon and never reaches the sea. An honest agent pays only one toll and keeps its share of rewards undiluted.",
