Overview of this book

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.

Hyperledger Fabric explored

Actors in the blockchain network: A blockchain is a network-based infrastructure where network-centric design, development, deployment, management, and support constructs apply. It is therefore vital to understand various actors and their roles that interact with the blockchain network for various purposes such as management, support, business users, regulator, and so on:

Each actor has a role and entry point and defines a governance structure that aids in network governance, audit, and compliance requirements. Business network governance (covered in detail in the following points) is an important compliance and costs consideration. Users are the parties who are users of the blockchain. They create and distribute blockchain applications and perform operations using the blockchain. These actors are consistent, and are based on cloud computing actors and roles from ISO/IEC 17788:

  • Developers: Blockchain developers are the actors who create applications for users (client...
