Beginning Blockchain is a book for those willing to learn about the technical fundamentals of Blockchain, practical implications, and hands-on development aspects of Blockchain applications. Adequate history, background, and theoretical aspects are covered to help you build a solid foundation for your Blockchain journey, and appropriate development aspects are covered with coding examples to help you jumpstart on Blockchain assignments. The first chapter introduces you to the Blockchain world and sets the context. The second chapter dives deeper into the core components of Blockchain. The third chapter is focused on Bitcoin’s technical concepts so what was discussed in the second chapter could be demonstrated with Bitcoin as a cryptocurrency use case of Blockchain. The fourth chapter is dedicated to the Ethereum Blockchain in an effort to demonstrate how Blockchain could be programmed for many more use cases and not limited to just cryptocurrencies. The fifth chapter is where you get the hang of Blockchain development with examples on basic transactions in both Bitcoin and Ethereum. The sixth chapter, as the final chapter, demonstrates the end-to-end development of a decentralized application (DApp). By the end of this chapter, you will have been equipped with enough tools and techniques to address many real world business problems with applicable Blockchain solutions. Start your journey toward limitless possibilities.
