Blockchain Quick Start Guide

By: Xun (Brian) Wu, Weimin Sun

Overview of this book

Blockchain is a technology that powers the development of decentralized applications.This technology allows the construction of a network with no single control that enables participants to make contributions to and receive benefits from the network directly. This book will give you a thorough overview of blockchain and explain how a blockchain works.You will begin by going through various blockchain consensus mechanisms and cryptographic hash functions. You will then learn the fundamentals of programming in Solidity – the defacto language for developing decentralize, applications in Ethereum. After that, you will set up an Ethereum development environment and develop, package, build, and test campaign-decentralized applications.The book also shows you how to set up Hyperledger composer tools, analyze business scenarios, design business models, and write a chain code. Finally, you will get a glimpse of how blockchain is actually used in different real-world domains. By the end of this guide, you will be comfortable working with basic blockchain frameworks, and develop secure, decentralized applications in a hassle-free manner.

DApp development tools

There are some popular blockchain web development tools used being by developers for creating a basic structure of a DApp project. The following sections list a few of these.



Truffle is an Ethereum DApp end-to-end development tool that provides a development environment for writing, compiling, and deploying test smart contracts and DApps. You can write HTML, CSS, and JavaScript for the frontend; Solidity is for smart contracts, and uses the web3.js API to interact with the UI and smart contract. Truffle Boxes provide helpful boilerplates, which contain helpful modules, solidity contracts and libraries, frontend code, and many other helpful files. The Truffle Boxes help developers to quickly get started with their DApp project.

The Truffle command line uses the following formats:

  • truffle [command] [options]

Here are the frequently used options in command-line tools:




Compile solidity contract files.
