Overview of this book

Ethereum is one of the commonly used platforms for building blockchain applications. It's a decentralized platform for applications that can run exactly as programmed without being affected by fraud, censorship, or third-party interference. This book will give you a deep understanding of how blockchain works so that you can discover the entire ecosystem, core components, and its implementations. You will get started by understanding how to configure and work with various Ethereum protocols for developing dApps. Next, you will learn to code and create powerful smart contracts that scale with Solidity and Vyper. You will then explore the building blocks of the dApps architecture, and gain insights on how to create your own dApp through a variety of real-world examples. The book will even guide you on how to deploy your dApps on multiple Ethereum instances with the required best practices and techniques. The next few chapters will delve into advanced topics such as, building advanced smart contracts and multi-page frontends using Ethereum blockchain. You will also focus on implementing machine learning techniques to build decentralized autonomous applications, in addition to covering several use cases across a variety of domains such as, social media and e-commerce. By the end of this book, you will have the expertise you need to build decentralized autonomous applications confidently.

Finishing the dApp

Your React.js web application looks great, what's left is to connect the smart contract to the functions in your application so they talk to each other while preserving that decentralization, since anybody is free to use the React application where they want without relying on a centralized server.

The first step in connecting a smart contract with a web application is to install web3.js since it's the bridge between Ethereum and web browsers, although you may not need it as we already have MetaMask. In any case, it's important to have it to select a stable version that won't change for our dApp. Go ahead and run npm i -S web3 on your project folder.
