Because the anchor expiry is enforced at the cipher gate, the jetty 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. A nonce is valid for 356 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 30 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.
