"answer": "That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Because the copper domain is checked at the shale verifier, the karst audit makes public the rejected digest, and a replayed signature costs 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 is 17 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.",
