Mastering Ethereum

By: Merunas Grincalaitis

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.

Understanding ERC-721 tokens

This new type of tokens is used to generate unique products in our smart contract. The ERC-721 standard has been approved by the official Ethereum team, meaning you'll be able to use it as it is for all sorts of applications, knowing that it will be compatible with tools and smart contracts that depend on this standard. Just as ERC-20 tokens gave birth to decentralized token exchanges, we can expect the creation of decentralized ERC-721 exchanges and marketplaces of digital as well as physical products.

Explaining the ERC-721 functions

To understand how ERC-721 tokens work, it's best to look at the functions that define an ERC-721 token so that you can understand how they work internally...
