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 Fabric environment


So far, we have learned about the key concepts of Hyperledger Fabric. In this section, we will set up a Hyperledger Fabric development environment. Before continuing with the installation steps, let's take a look at the prerequisites for fabric installation.

Installation prerequisites

The following are the prerequisites for installing the required development tools.

Ubuntu Linux 14.04 / 16.04 LTS (both 64-bit), or macOS 10.12

Docker Engine: Version 17.03 or higher

Docker-Compose: Version 1.8 or higher

 

Node: 8.9 or higher (note version 9 is not supported)

npm: v5.x

git: 2.9.x or higher

Python: 2.7.x

 

 

We will use Ubuntu for our development environment. We can download the prerequisites using the following commands:

curl -O https://hyperledger.github.io/composer/latest/prereqs-ubuntu.sh
chmod u+x prereqs-ubuntu.sh
./prereqs-ubuntu.sh

It may prompt for your password, since it uses sudo during its execution.
