The Blockchain Basics by Daniel Drescher. This is a very basic blockchain book. I would recommend this to someone completely unfamiliar with blockchain. Daniel hits his mark. Drescher places a repeated template for each step. In this design, I felt the book had trouble flowing for anyone who has already read a blockchain textbook.
Daniel pushes the elementary lessons through 25 steps.
There is a very basic outline to the security of the blockchain. Again this book has a specific target audience: Newbie.
I have to admit that I was bored reading the text. yet was impressed by the lessons and related topics that are presented.
