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.

Launching a sample trade network

So, now that we have all the configuration for our network, and also the channel artifacts and cryptographic material required to run it, all we need to do is start the network using the docker-compose command, as follows:

docker-compose -f docker-compose-e2e.yaml up

You can run this as a background process and redirect the standard output to a log file if you so choose. Otherwise, you will see the various containers starting up and logs from each displayed on the console.


Note that on some OS configurations, setting up Fabric can be tricky. If you run into problems, consult the documentation. A detailed description of how to install a Fabric network and examples is provided at

The network can be launched in the background using our script as well; just run:

./ up

From a different terminal window, if you run docker ps -a, you will see something as follows:
