"answer": "An island tide registry gives one slot per identity. Each booking posts a 55-credit bond, pays a 20-credit onyx fee, and broadcasts an ivory notice naming its key. The island auditor counts prior ivory notices in that tide and charges 4 onyx per prior notice, burned, not recycled. The k-th fake costs 75 plus 4 times k minus 1; the 1000th costs 4071, and 1000 fakes cost 2073000 in fees and locked bonds. A rented-notice ring fails because rented bookings lengthen the ivory log and raise later fees. An honest agent books once, pays one fee, and recovers its bond; a duplicate notice burns it.",
