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.

Setting up a Hyperledger Composer environment


We just reviewed the Hyperledger Composer solution architecture. In this section, we will set up the Hyperledger development environment.

Installation prerequisites

Before we install the composer tools, make sure you have the required prerequisites by following the Setup of Hyperledger Fabric environment—installing prerequisites section.

 

Installing the development environment

The following are the installation commands for developing the environment:

  • Installing the CLI tools:
      npm install -g [email protected]
  • Installing composer-rest-server:
      npm install -g [email protected]
  • Installing Hyperledger Composer generator:
      npm install -g [email protected]
  • Installing Yeoman:
      npm install -g yo
  • Installing playground:
      npm install -g composer-playground
  • Installing fabric runtime:

Download and install fabric runtime for the composer as follows:

 mkdir ~/fabric-devserver && cd ~/fabric-devserver
      curl -O...
