✦ Synopsis

With the recent debacle surrounding the cryptocurrency exchange FTX and the crypto trading company Alameda Research, the importance of grasping the security and regulation of Web3, cryptocurrency, and blockchain projects has been magnified. To avoid similar economic and security failures in future Web3 projects, this book provides an essential guide and a comprehensive and systematic approach to addressing security concerns. Written by experts in tech and finance, it provides an objective, professional, and in-depth analysis of security and privacy issues associated with Web3 and blockchain projects. The book primarily focuses on Web3 applications and ecosystem components such as the stablecoin, decentralization exchange (DEX), decentralized finance (DeFi), non-fungible token (NFT), decentralized autonomous organization (DAO), and crypto exchange. It also discusses various security issues and their manifestation in Web3 such as ransomware, supply chain software attacks, AI security, and quantum security. Moreover, it provides valuable countermeasures and best practices for individual users as well as Web3 application development teams to consider when designing and implementing Web3 applications. This book is an excellent resource for a diverse range of readers and will particularly appeal to Web3 developers, architects, project owners, and cybersecurity professionals seeking to deepen their knowledge of Web3 security.
