This book will guide you through the enjoyable, practical, and hands-on process of learning how to create decentralised applications (DApps) on the Ethereum blockchain using the Solidity programming language. Within minutes, you'll begin creating your own Ethereum smart contract. Every part is brief and to the point since I don't want to spend your time (or, most definitely, mine) on information you don't need to know. In the end, you will possess the skills necessary to create a functional decentralised eBay clone application.

We learn how Ethereum functions and why we should care about it in the first chapter. In the second chapter, we'll use Ethereum to build our first functional smart contract, teaching us how to operate with the platform as developers.

Chapters three and four will then be where we learn about building, deploying, and testing Ethereum apps. All of them will get us ready for chapter five and chapter six's creation of our decentralised eBay clone smart contract and the React user front end.

This book aims to show you how to use Ethereum to create decentralised applications. We won't spend a lot of time discussing trading cryptocurrencies, purchasing Ethereum, or exchanging Ethereum (ether) coins. We will provide a thorough review of Ethereum and cryptocurrencies, but we won't get into a hyper in-depth academic study of either because the goal of this book is to provide readers with the skills they need to work with Ethereum and create products using it.
