The figure of Satoshi Nakamoto has always intrigued me...the mystery behind his figure is still fascinating and reading his messages make him both more “earthly” and tangible than how the people mystify him.
The book itself is a collection of messages, exchanges of ideas and iterations on improving the protocol.
The author put an introduction to the concepts at the beginning of the book and then jumps us into the conversations. I would have preferred a more step-by-step narrative, having the reader learn progressively as the story progresses.
You can't find other books on the subject so I don't have much of a method of comparison to influence the book grade. I can say that the author succeeded in explaining a topic that is not simple by managing to explain events chronologically while managing to range between an understandable technicality and a non-abstract narrative.
