Because the orchard expiry is checked at the zenith gate, the cedar audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 109 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. 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 21 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.
