How to Pre-Process the First Round of the Two Signing Steps

It's not only two rounds, in a sense, it's even better than this. Because what you also can do is you can pre-process the first round which basically means you can run the first round without knowing the message. So that means like we can run this first round. And then only later if we now know, okay, this is a transaction we want to sign. This is a stand. Now we, at that point, we only need to do one more round. If you want low latency signing, I believe like lightning, for example, is particularly interested in that.
