Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

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

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 https://hyperledger-fabric.readthedocs.io/en/release-1.1/samples.html.

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

./trade.sh up

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

CONTAINER ID  ...
