"answer": "Because the tide expiry is applied at the kernel gate, the nadir audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 498 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Running many aliases hence means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. That is 7 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.",
