"answer": "Admission burns sponsorship chits, not cash. Each established identity mints a chit every five epochs: one quill signature, one newcomer, single-use, unsellable. A joiner needs four chits, signed at four knoll points by separate sponsors, all crossing one river with a single slot per block, killing parallelism. A sponsor whose recruit turns sybil forfeits future minting. Inserting n fakes needs 4n real chits, yet a self-grown cluster mints one per member per five epochs, driving cost to 0.8n squared slots. Ruinous by a hundred: a rope bridge signed plank by plank by those already across.",
