"answer": "Because the haven expiry is enforced at the grove gate, the zenith audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 290 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 12 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.",
