Which probably won't convince those of us who are skeptics that it's possible. It needs to be technically possible, but easy enough to verify for the average user that someone can't just claim they're doing it the right way but doing something fraudulent instead. There's good reason to be skeptical here. But arguing that all they're trying to do is make public accounting isn't the right counter argument here.
