Programming with Bitcoin Core and Lightning

(Or: Programming Bitcoind and Lightningd)

This is a tutorial for working with Bitcoin (and Lightning) that teaches direct interact with the severs themselves, as the most robust and secure way to begin cryptocurrency work.

NOTE: This is a draft in progress, so that I can get some feedback from early reviewers. It is not yet ready for use.

Introduction

The best way to learn deeply about bitcoin is to avoid GUIs (even bitcoin-qt), and instead learn it from the command line.

Requirements

This tutorial assumes that you have some minimal background of how to use the command line interface. If not, there are many tutorials available, and I have one for Mac users at https://github.com/ChristopherA/intro-mac-command-line
