▶Book Description
Blockchain and Hyperledger technologies are hot topics today. Hyperledger Fabric and Hyperledger Composer are open source projects that help organizations create private, permissioned blockchain networks. These find application in finance, banking, supply chain, and IoT among several other sectors. This book will be an easy reference to explore and build blockchain networks using Hyperledger technologies.
The book starts by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. You will learn how to configure Hyperledger Fabric and become familiar with its architectural components. Using these components, you will learn to build private blockchain networks, along with the applications that connect to them. Starting from principles first, you’ll learn to design and launch a network, implement smart contracts in chaincode and much more.
By the end of this book, you will be able to build and deploy your own decentralized applications, handling the key pain points encountered in the blockchain life cycle.

The simple and well organized content will put novices at ease with blockchain concepts and constructs.
▶What this book covers
⦁ Chapter 1, Blockchain - Enterprise and Industry Perspective, you've heard about blockchain and you are wondering, What is all the fuss about? In this chapter, we explore why blockchain is a game changer, what innovation it brings, and what the technology landscape is.
⦁ Chapter 2, Exploring Hyperledger Fabric, with an understanding of the blockchain landscape, we turn our attention to Hyperledger Fabric. The aim of this chapter is to walk you through the deployment of each component of Hyperledger Fabric while unveiling/building the architecture.
⦁ Chapter 3, Setting the Stage with a Business Scenario, describes a business use case and then focuses on understanding the process of creating a good business network using blockchain from requirements to design.
⦁ Chapter 4, Designing a Data and Transaction Model with Golang, aims to define what makes up a smart contract in Hyperledger Fabric. It will also introduce you to some terms regarding smart contracts and get you to experience the development of a chaincode using the Go language.
⦁ Chapter 5, Exposing Network Assets and Transactions, leveraging the smart contract written in the previous chapter, this chapter looks at the required integration of application to the network. It takes the readers through the process of configuring a channel, and installing and invoking chaincode, from a client application and considers the various integration patterns that might be used.
⦁ Chapter 6, Business Networks, has an objective to introduce and uncover the skills and tools needed to model a business network. Working at a higher level of abstraction, the foundation, tools, and framework will provide the reader with a way to quickly model, design, and deploy a complete end-to-end business network.
⦁ Chapter 7, A Business Network Example, putting the concepts of Chapter 6 into practice, this chapter walks through the steps to deploy a full business network from end user application to smart contracts.
⦁ Chapter 8, Agility in a Blockchain Network, focuses on the aspects required to maintain agility in a blockchain network. Applying DevOps concepts, the reader is presented with a continuous integration / continuous delivery pipeline.
⦁ Chapter 9, Life in a Blockchain Network, aims to raise the reader's awareness on the key activities and challenges that organizations and consortium may face when adopting a distributed ledger solution, ranging from management of application changes to maintenance of adequate performance levels. A successful network deployment will hopefully see many organizations join it and the number of transactions increase.
⦁ Chapter 10, Governance –.The Necessary Evil of Regulated Industries, governance is a necessary evil for regulated industries, but governance is not required only for business network that deal with use cases for regulated industries. It is also a good practice to ensure longevity and scalability of a business network. This chapter explores vital considerations for production readiness for any founder-led blockchain network.
⦁ Chapter 11, Hyperledger Fabric Security, lays the foundation for security design of blockchain networks. Various security constructs are discussed and Hyperledger Fabric security is explained in detail. An essential chapter to understand security design considerations.
⦁ Chapter 12, The Future of Blockchain and the Challenges Ahead, looks ahead and discusses the challenges and opportunities that lie ahead. Through the use of open technologies, it invites readers to engage in and promote the blockchain innovation agenda.
