Overview of this book

Blockchain is a technology that powers the development of decentralized applications.This technology allows the construction of a network with no single control that enables participants to make contributions to and receive benefits from the network directly. This book will give you a thorough overview of blockchain and explain how a blockchain works.You will begin by going through various blockchain consensus mechanisms and cryptographic hash functions. You will then learn the fundamentals of programming in Solidity – the defacto language for developing decentralize, applications in Ethereum. After that, you will set up an Ethereum development environment and develop, package, build, and test campaign-decentralized applications.The book also shows you how to set up Hyperledger composer tools, analyze business scenarios, design business models, and write a chain code. Finally, you will get a glimpse of how blockchain is actually used in different real-world domains. By the end of this guide, you will be comfortable working with basic blockchain frameworks, and develop secure, decentralized applications in a hassle-free manner.

We have reached the end of this chapter. In this chapter, we have overviewed Hyperledger Composer and installed the related tools. We used composer model language to develop the same insurance claim use case as in Chapter 5Exploring an Enterprise Blockchain Application Using Hyperledger Fabric, and deployed it to the fabric network. Lastly, we integrated the application with a composer REST server to generate a client API and interacted with these APIs from the web.

At this point, you should be comfortable working with Hyperledger Composer. Now that we're at the end of this chapter, we have learned about the two most popular public and enterprise blockchains. As a blockchain developer, you should have the basic blockchain knowledge to be able to write your blockchain application. In the next chapter, we will discuss the various real world blockchain use cases.
