"answer": "A harbor admits only 100 new identities per epoch, each berth to the highest sealed bid. A newcomer locks a ferrous bid bond: winning bids burn, losing bids return. An attacker chasing many berths must outbid honest applicants, so each bid pushes the price higher in a spiral from 10 toward 35 credits. The marginal cost of the k-th identity is the clearing price after k bids, so it grows with k: 100 fakes cost at least 3,500 credits. The named failure mode, straw-bidder laundering, fails: a winning straw bid burns too. One honest agent pays once and keeps an undiluted share.",
