"answer": "Each identity locks a 90-credit cedar bond and registers one non-transferable nectar receipt, issued when a local merchant confirms a purchase over the zephyr channel. A merchant may vouch for at most three identities per epoch, and the cedar ledger publishes each receipt hash. Auditors recheck 5% of receipts; a reused or forged receipt burns the bond and slashes the merchant bond. The kth fake pays 90 plus a 40 fee, so 1,000 fakes lock 90,000, pay 40,000, and need 334 merchants. A rented-merchant ring fails at the fourth vouch. An honest agent pays once: 90 locked, one fee.",
