Hadn't seen that one, thanks. Insane the amount of innovation going on
I started with that one, later dived into this doc below.

Discussion
I just can't keep up and I was behind to start with. I think I need to enroll on a course in cryptography, cybersecurity and programming. Any suggestions?
This book must be good with hands on coding exercises. I have been listening to the author for a while. He is also Bitcoin developer.
