Setup up a Bitcoin Lightning point of sale in Common Lisp
Because I can, I recently added support for testnet Bitcoin Lightning payments into this website. The beauty of Freedom and privacy respecting software is that you can do anything you want with it.

Bitcoin is art
Bitcoin is this strange thing I don’t fully understand. Going down the rabbit hole, as it is commonly known, I generally feel disappointed. Whenever I meet a bitcoiner, it is always a fanatic insisting that I buy bitcoin instead of a supportive mentor.

Elliptic Curve Digital Signature Algorithm - Bitcoin & Haskell
The previous posts covered mathematical curiosities. Now we can leave that realm, find an application and turn them into tools to work with elliptic curve cryptography. That means finding and choosing which particular values of the parameters bring us into a curve we can use for cryptography.

Elliptic Curves on Finite Fields - Bitcoin & Haskell
When merging the last two posts, I immediately run into serious difficulties. Haskell’s type system just made my work harder(well my ignorance did). Until I could come up with a solution, I could not appreciate how the strictness of the type system actually gives flexibility.

Elliptic Curves - Bitcoin & Haskell
In this series of posts I’m solving the exercises of Programming Bitcoin1 in Haskell, I’m learning Bitcoin and Haskell in one go. To describe a point in the elliptic curve, we need four data points.

Finite Fields - Bitcoin & Haskell
Bitcoin’s price has gone crazy up, and now I’m really responsible for learning it. I found the book Programming Bitcoin1 by Jimmy Song, it looks good enough to give it a try.

Getting started with bitcoin
Bitcoin is all over the news, this time with big investors pouring money into it, a global pandemic that put the economy on hold, and governments printing money like crazy. Price raises, it is a bubble again.
