"answer": "Because the ember salt is published after the mirror checkpoint, the tide audit recomputes each digest and a prepared batch fails verification. Answers are salted with a 74 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. An operator running 123 keys thus pays for 123 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. That is 35 dollars per alias. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.",
