The book offers an excellent guide to understanding Blockchain technology for beginners. Those who are unfamiliar with this technology can gain a better understanding of the contents if they avoid technical details. However, some terms will be more understandable if you have some IT background. It isn't necessary, though. It has been written in everyday English to avoid confusion, and it will walk you through the entire process of how digital currency was created step-by-step. Our goal is to understand what caused the birth of several cryptocurrencies in our current society by going back in time and summarizing the history of finance. We then examine the primary objective behind the invention of Bitcoin as well as the theory behind it. As we move forward, we should review some of the possible candidates for the birth father of blockchain. The next part of our discussion will describe what a distributed ledger is and how it operates. Afterward, the miners are introduced, their responsibilities, and who they are. Then it discusses how the blocks are created, and finally, how the blocks culminate into a chain called a Blockchain. We will discuss in more detail what security measures we have put in place on the Blockchain in the last chapters. In addition, by examining the purpose of this technology and future banking systems, we will attempt to understand why it will change the world. To conclude, here is a quick explanation of what Blockchain is. It's no doubt that there are many books available on this subject, so thanks for choosing it! I have taken every necessary step to make sure the book is packed with useful information. Have fun!
