Over the past three years, the landscape of blockchain technology has undergone remarkable transformation, extending far beyond its association with cryptocurrencies especially with the emergence of Web3 applications.

Web 3.0 is built using artificial intelligence, machine learning, and the semantic web. It uses all this to process and interpret information with human-like intelligence. And for security, Web 3.0 uses the blockchain security system to keep information secure. This book aims to provide an overview of the evolution of blockchain technology, highlighting its expanding use cases and exploring the latest trends and news that have shaped the blockchain landscape in recent years. The timing of this book is ideal. NFTs, DeFi, and in general the emergence of the architectural concept of "Web3" are defining and will define the future of web applications.

The book takes the reader on a journey across the innovative use cases of blockchain technology, with a focus on building the technical foundation of such applications, in order to enable entrepreneurs and blockchain architects to create state-of-the-art Web3 solutions.
