The answer stamp difficulty is 12 bits for a fresh identity and falls as the identity accumulates clean history, so age is rewarded and youth is taxed. Because the difficulty is read from the lantern table at the ivory gate, the operator pays proof of work per key, and the echo audit records the value used. Minting 200 aliases therefore starts every one of them at the hardest setting, which makes the first answer from each the most expensive it will ever be. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.
