A dissection of bitcoin

Instead of presenting you yet another conceptual account of Bitcoin, I will dissect the Bitcoin source code: I will open the black-box, examine all its parts, and show you how to put them back together to build a complete system. Code is the ultimate expression of design. It reflects the behavior of a software system as it is, and it reveals the inner-workings of the system in a plain and straightforward way. The Bitcoin source code is the ultimate answer to the question "how Bitcoin works".

Indeed, it is the ultimate answer to any question you can ever possibly ask about the Bitcoin system. After Satoshi Nakamoto released the original code and disappeared from the public eye in , the Bitcoin Foundation took over the control of the subsequent developments. This books covers version v0. It is one of the original versions written by Satoshi and the earliest version available in GitHub. It contains about 16, lines of code after removing all the empty lines , and thus a complete coverage of the whole code base in a book is a manageable task.

The later versions developed by the Bitcoin Foundation did not change the original architecture. Understanding this original version will give you a solid foundation for further exploring of the later versions. Indeed, if you compare this version with the later ones, you will find that all the important classes are unchanged, and that many important functions are kept the same name. Another reason to cover this version is that its coding style is classic: dense and concise.

That is how Satoshi managed to implement such a complicated system in just 16, lines of code. This version keeps all the system states in global variables. Once you get familiar with these variables and understand what they do, which, of course, takes some time and efforts, reading the code becomes a fairly enjoyable endeavor. You will not suffer from the typical code-reading fatigue caused by a programming style in which "everything happens somewhere else" a quote from Adele Goldberg.

Everything happens right there in the place where it supposes to happen, cleanly and precisely. Who should read this book This book is intended for readers who want to acquire a thorough knowledge of Bitcoin. After finishing this book, you will not only appreciate the revolutionary ideas behind Bitcoin, but also acquire in-depth knowledge of the design principle of the Bitcoin software system, and master the implementation details of the system.

Reading good code is a great way to master a programming language. That being said, this is not a light book to read. This book is technical in nature. It covers many implement details. You will have to understand one detail before moving on to the next one; and there seem to be endless of them.

The best way to read this book is to be patient and persistent, take on one detail at a time. After working out enough details, you will reach a tipping point where a big picture will emerge. From that point on, everything will fall into its own place, and the whole structure of the system will become crystal clear to you. Free e-book and full version The first 4 chapters of this book is published as a free e-book at Amazon and Apple iBooks Store. You can find it by searching "A Dissection of Bitcoin" at one of these on-line stores.

Bitbucket gives teams one place to plan projects, collaborate on code, test, and deploy.
