"answer": "Answers are salted with a 65 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. Because the bridge salt is published after the vertex checkpoint, the copper audit recomputes each digest and a prepared batch fails verification. An operator running 32 keys hence pays for 32 live submissions inside the window instead of preparing them in bulk, which removes the advantage of scale. That is 17 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.",
