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.

Writing chaincode


Chaincode is similar to a smart contract. It defines and executes the business logic invoked by authorized participants in a specific network. A chaincode is written in Go or Node.js. In our example, we will use Go.

There are many IDEs and tools to support Golang. Here are some popular IDEs that work great with Golang.

Development tools

There are various tools that support Go development. Some popular IDEs are listed in the following sections.

LiteIDE 

LiteIDE is an open source Go IDE that was directly designed for Golang. There are a bunch of useful features available for Go developers, including a configurable code editor, customized build commands, many building options, and Golang support.

JetBrains Gogland

Gogland has a powerful built-in autocomplete engine, errors detection, code refactoring tools, and more.

Visual Studio Code

You can install Go extension in Visual Studio Code. It provides code hints and the ability to debug code.

In this chapter, we will use LiteIDE to develop...
