"answer": "Because the beacon domain is checked at the ferrous verifier, the inlet audit shows the rejected digest, and a replayed signature burns the operator its bond. Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 5 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. A farm of 170 pays that 69 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.",
