I have gone through the book "Mastering Bitcoin" and I am not able to completely grasp it. I just need a break from reading and need to do something practical.
Is "
https://github.com/bitcoin/bitcoin/" is the original copy?
How should I read the source code?
Do I need to install some specific program /compilers for it
Mastering bitcoin will explain how bitcoin works, not only how bitcoin core software works.
The author suggests that you can skip one chapter (related to bitcoin core commands) and go back later. I did that, and it was good. I am not a developer and got a nice understand from the book.
Even if you are focused in Bitcoin core commands , I think you should read the whole book first to understand what it can really do and how, before trying to learn by yourself on GitHub.
