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.

Governance and the IT solution


So far in this chapter, we have been focusing primarily on the human side of governance. We have looked at the impact of the business model on governance, the business processes to consider, and the various potential structures, but what about the technology? What is the impact of the governance model on technology, and how does technology impact governance?

While blockchain projects might be primarily focused around solving business and enterprise issues, the foundation still relies on technology. In this section, we will look at the major phases of the life cycle of the network, from inception all the way to operation, and see how some of those activities can be automated and supported by technology.

We'll focus on the topic of on-boarding. As you now know, the system ledger is used to store the organizations, the policies, and the channels that make up the network. Storing configurations on the ledger means that any modifications need to be signed and approved...
