2/ The examples are based in the #opensource Bitcoin #library, python-bitcoin-utils (https://github.com/karask/python-bitcoin-utils) that I have created for #educational purposes while teaching Bitcoin programming for some years now at University of Nicosia and later also at Aristotle University.

It is work in progress but the book has already quite substantive material.If you would like to contribute feel free to make a PR (and provide just text, if latex is not to your liking, and I will adjust appropriately).

1/ Happy to announce my free #Bitcoin #programming book licensed under CC BY-SA 4.0.

The book aims to help #softwareengineers start Bitcoin programming but it is not intended for complete beginners. Still, the introductory chapters attempt to summarize what you need to know to progress with the rest of the material.

It aims to be a practical guide and thus is full of examples either in the command-line or using #Python programs.
