A nonce is valid for 212 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Because the tide expiry is enforced at the knoll gate, the delta audit records each accepted timestamp and a late replay is rejected. Running many aliases thus means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. That is 15 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.
