In my first book, titled ‘Block Chain for Beginners, ‘ we covered the blockchain ecosystem at a high level and provided an overview of the entire process. This book will dig deeper into blockchain and focus on security.

Despite being over a decade old, blockchain only began within the previous few years. During this point, it’s moved from a fad to the topic of great research by various companies, including everything from startups to large tech companies to governments.

In this book, you will begin with the basics of the blockchain and examine different attacks against the blockchain against users’ wallets, as well as denial-of-service attacks and mining attacks against pools. You will explore the usage and types of blockchain channels and how they control users’ access to data across networks. We show you the basics of blockchain technology, its core components, and transaction protocols used by the technology to ensure the security of the transfer of information.
