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.

Chapter 9. Life in a Blockchain Network

Your Fabric network should now be set up and running your application connecting different entities through a smart contract and serving users through a web interface. In addition, to help your developers and system administrators maintain code, push updates, and manage network configuration, you should have instituted a process whereby system testing and maintenance can be done with safeguards in place and no interruption to service.

Yet, this will not be the terminal state of your application. Needs and expectations evolve, and this is especially true for an application that involves multiple collaborating entities, all of whom will have differing requirements at different points in time. In addition, it is expected that software itself will continually change and evolve even if the nature and function of an application is kept intact. Finally, any distributed service-oriented application (a description that can be applied to any Hyperledger Fabric...
