Blockchain is the new breed of innovation that has already begun to reinvent trade, social and political relationships, and any other form of exchange of value. For once, it's not just a transition, it's a strong trend already in practice. As of this writing, over 40 top financial organizations and many different companies across industries have begun investigating blockchain to minimize transaction costs, speed up transaction time, reduce fraud risk, and remove intermediary or broker services. Some are trying to re-imagine legacy systems and services to take them to a new level and develop new types of service offerings as well.
Throughout the book, we will discuss blockchain in more detail. If you are new to blockchain or select only those relevant to you, you can follow through the chapters in the order presented. In the public conversation and in the media, the blockchain has received a lot of attention. Many fans contend that the blockchain has been the best innovation since the Internet emerged. Therefore, a lot of books and articles about the blockchain have been written over the past few years. Nevertheless, if you want to know more about how the blockchain operates, you may be lost in a universe of books that either easily skip over the technical details or highly systematically analyze the underlying technical concepts. The former may leave you unsatisfied because they fail to clarify the technical details necessary to understand and appreciate the blockchain, while the latter may leave you unsatisfied because the knowledge you want to learn is already needed."
