"answer": "Under sibling-doubling mint fees, every identity created from the same sponsor key pays a join fee of base times 2^(n\u22121), where n is that key's existing sibling count on the jetty network. A lone agent landing after the zephyr crossing pays only the base 10 tokens, while a dune-dwelling farm spawning fakes from one key faces 10, 20, 40, 80 tokens and beyond, so k fakes cost 10\u00d7(2^k\u22121): ten fakes already exceed 10,000 tokens. Sponsor keys must burn fees irreversibly, making mass identity creation nonlinearly expensive while honest single agents pay almost nothing.",
