This book is designed to give you an insight into the world of Ethereum blockchain and enables you to make your own cryptocurrency using Ethereum. Throughout this book, you will be learning about various concepts and applying that knowledge directly, while also being introduced to the wide scope of functionality that Ethereum blockchain will be providing in the future.
If you are anyone who is passionate about knowing how blockchain works, or if you are an enthusiast who wishes to work on cryptocurrencies or has an interest in hacking, then this book is meant for you.
Chapter 1, Workflow Setup and Thinking Blockchain, focuses on recapping the basics of Ethereum blockchain. We will go through some examples and real-life projects, trying to get you into that blockchain mindset. Then, we will set up the workflow, and the tooling around it, using npm.
Chapter 2, Developing Your First Decentralized Application with Ethereum, looks at developing your first payment application with Ethereum.
Chapter 3, Creating Your Own Cryptocurrency on the Ethereum Blockchain, takes you through how to create your own cryptocurrency on top of Ethereum blockchain.
Chapter 4, Signing Legal Documents on Blockchains and Identity Verification, will show you how you can work with legal documents and identity on Ethereum blockchain.
Chapter 5, Ethereum Outside the PC/Web Environment, explores how you can use Ethereum outside PC or web environments. We will also look at some further steps and where you can take all these lessons from here.
Knowledge of at least one object-oriented language is required. It's very good if you know some JavaScript.
We are going to make extensive use of NPM, and we are going to recap the basics of blockchain, but some prior basic knowledge is always beneficial, of course.
