Book Description

Web3, the new blockchain-based web, is often hailed as the future of the internet. Driven by technologies such as cryptocurrencies, NFTs, DAOs, decentralized finance, and more, Web3’s aim is to give individuals more control over the web communities they belong to. Whether you’re a beginner or an experienced developer, this book will help you master the intricacies of Web3 and its revolutionary technologies.

Beginning with a concise introduction to blockchain and the Ethereum ecosystem, this book quickly immerses you in real-world blockchain applications. You’ll work on carefully crafted hands-on exercises that are designed for beginners as well as users with prior exposure. The chapters show you how to build and deploy smart contracts, while mastering security controls and discovering best practices for writing secure code. As you progress, you’ll explore tokenization and gain proficiency in minting both fungible and non-fungible tokens (NFTs) with the help of step-by-step instructions. The concluding chapters cover advanced topics, including oracles, Layer 2 (L2) networks, rollups, zero knowledge proofs, and decentralized autonomous organizations (DAOs).

By the end of this Web3 book, you’ll be well-versed in the Web3 ecosystem and have the skills to build powerful and secure decentralized applications.
