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 8. Agility in a Blockchain Network

At this point, if all went well, you should have a fully functional decentralized application, with the associated smart contracts running on Hyperledger Fabric. With this knowledge in hand, life is going to be good, right? Well, like anything, solutions evolve over time. It could be a change in regulation, the introduction of a new member in the consortium, or a simple bug in your smart contract—whatever the cause, the solution will grow, and without solid development and operational practices, changes will be slow and your life will be painful.

Considering that maintaining agility in the development processes of an IT organization is already very challenging, how can it be done in a consortium? How can companies of various cultures with different velocities come together to deliver and maintain the solution in a time frame that allows them to maintain the competitive edge that the network provides?
