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.

Tools for solidity development environment

Smart contract development is still in its infancy. Creating such contracts and interacting with them in a convenient manner can be done in a multitude of ways.  The following powerful tools can be used to build, monitor, and deploy your smart contracts for development on the Ethereum platform.

Browser-based IDE

In this section, we will be looking at onlien browser based tools such as Remix and EthFiddle.


Remix is a powerful, open source, smart contract tool that helps you write solidity code just from the browser. It supports compile, run, analysis, testing, and debugger options. The following three types of environments are available with Remix when developing and testing:

  • JavaScript VM: Remix comes with five Ethereum accounts, and each account is deposited with 100 ethers as default. This is convenient for testing smart contracts in the development phase. Mining is not required as it is done automatically. This option is a good choice when you...
