Blockchain is a revolutionary technology and Ethereum is a decentralized blockchain platform that runs smart contracts.

Hands-On Blockchain Development in 7 Days will teach you how to build an online gaming application using the Ethereum blockchain. Each section of the book will introduce fundamental blockchain programming concepts as they relate to creating an online game, followed by practical exercises that you can implement as homework assignments. With this book, you will gain core blockchain application development skills to do with creating smart contracts, interacting with the Ethereum network, building user interfaces, and deploying your application to the internet. This book supplies seven self-contained lessons taught in a practical, hands-on way.

By the end of the book, you will be amazed at how much you will have learned about blockchain application development on the Ethereum network in just one week!

This book is for software engineers and IT professionals who are eager to gain blockchain application development skills and want to master the development of blockchain applications. This book is perfect for those with limited programming experience.

, Day One - Application Introduction, Installation, and Setup, walks us through the basic setup of the environment that is required for running our application. We will learn about what our application does and how it does it. We will learn about the various tools that we will use to interact with the blockchain.

, Day Two - Solidity Variables and Data Types, teaches us all about Solidity as a programming language. It shows us how to write code for Solidity, the different types of variable available in Solidity, and looks at how to implement them.

, Day Three - Implementing Business Logic in Your Smart Contracts, shows us what smart contracts are and how they can be used to work with blockchain applications. Then, we will learn how to write business logic inside those smart contracts, so that our application functions as it's supposed to.

, Day Four - Creating Tests, shows us how important tests are. We will be using tests extensively in this book to ensure that our code is running without any issues. This chapter shows us the various types of tests, looking at how to create them and how to use them to improve our application.

, Day Five - Building a User Interface, teaches us all about the React framework, which we will be using as the backend to create our UI for the application. We will learn how to interact with our blockchain network via the UI, we will learn how to ensure it functions properly, and we will learn how to connect our application to the network via the UI.
