Hey man! Thank you. Yes, I followed those discussions, I think scheme is pretty solid. Most of the issues that came up are really implementation-based. Coding up the basic mechanics in a few days was a real trip!

What still fascinates me is that the equations for the blind signature scheme used in Cashu can be summarized in a couple of lines. Here is the gist that @rijndael was referring to: [Link](https://gist.github.com/RubenSomsen/be7a4760dd4596d06963d67baf140406)

I remember when you first put cashu out, the blind signature scheme was (or at least looked like) a quick python implementation of a gist that rubin somsen wrote. It looked like waxwing and a bunch of other folks have chimed in on the gist about the soundness of the scheme, but I haven't been following it. What's the state of that whole thing.

Also, why do people keep coming up with bad metaphysical analogies for bitcoin?

Love your work and appreciate all you do. Hope you have a nice holiday season.
