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.

Network bootstrap and governance – the first step towards security

When organizations decide to form a permissioned private blockchain network using Hyperledger Fabric, they need to consider several governance aspects, which will ultimately determine the overall security posture of the network. These governance aspects include, but are not limited to the following:

  • How shall the network be bootstrapped and the members verified to create the network? Network bootstrap is the first step in creating a blockchain network. Different entities may come together to create a network. The entities may have an out-of-band communication to agree upon with the first set of members and establish governance policies, which will be discussed next.
  • What is the process for a new entity to join the network (or a channel)? Defining a policy for admitting new members in the network is paramount and is governed by the business needs of the network.
  • Who can deploy and upgrade chaincodes on peers in the network? Defining...
