"answer": "A non-refundable sybil tax gates admission: each identity must forge a single-key receipt for a 30-credit payment that is burned, not refunded. The receipt goes to the reef ledger, which verifiers check before granting weight. The k-th fake identity pays the same 30 credits, so cost rises linearly: 1,000 fakes burn 30,000 credits, while an honest agent pays 30 once. Receipts cannot be reused, so one payment never covers two slots. Rented payment finds no haven: a landlord for many applicants burns 30 per applicant, and a reused receipt is rejected because the reef ledger marks it spent.",
