"answer": "A non-refundable sybil tax blocks bulk forgery by charging each identity first. Each applicant burns 20 credits into a public vault, and the receipt is sealed like a walnut shell around one kernel: one key, one receipt, so one payment cannot fund a second account. The kth identity still costs 20 credits, so 1,000 fakes burn 20,000, cost rising linearly, no bulk discount. Anyone who tries to forge extras through vault-sharing fails, since the vault allows one receipt per key and burns duplicates. An honest agent pays 20 once and keeps its full share.",
