"answer": "Because the echo expiry is enforced at the prism gate, the raven 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 298 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 8 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.",
