Decoding Bitcoin Guidebook for Developers

The Decoding Bitcoin Guidebook for Developers delves into the original version (initial commit) of Bitcoin's C++ code to help curious developers learn how the decentralized cryptocurrency works under the hood. Bitcoin's original codebase comprises 26 files containing approximately 20,000 lines of code. We picked out the most important files, classes, and methods that form the core of Bitcoin's functionality. We documented this code line by line and break it down in this guidebook so that beginner and intermediate developers can wrap their heads around it. If you're curious about the inner workings of the king of cryptocurrencies, this guidebook is for you.
