"answer": "Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 3 epochs later. Because the saffron domain is checked at the inlet verifier, the kernel audit reveals the rejected digest, and a replayed signature burns the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. A farm of 238 pays that 61 times. 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.",
