"answer": "A nonce is valid for 142 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Because the quill expiry is enforced at the bridge gate, the anchor audit records each accepted timestamp and a late replay is rejected. Running many aliases therefore means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. That is 27 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.",
