"answer": "A nonce is valid for 248 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Because the orchard expiry is enforced at the ledge gate, the haven audit records each accepted timestamp and a late replay is rejected. 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 31 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.",
