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.

A description of the business network

The READ.ME file contains a natural language description of the network in terms of its assets, participants, transactions, and events.

The participant descriptions

The participants are listed in the business network description:

 Customer, BankEmployee

In our example, there are four participant instances—Alice and Bob, Matias and Ella. But notice how there are only two participant types, namely Customer and Employee. In our network, Alice and Bob are participants of the Customer type, whereas Matias and Ella are participants of the BankEmployee type. We can see that these types are named from the perspective of a bank–that's because the network service is being provided by the Dinero and Eastwood banks, and used by Alice and Bob. We're going to see more details about these participant types and the particular instances in the network soon. But for now, just think about how we've reduced the actors in the network to two very simple representations...
