The rise of blockchain technologies has impacted various sectors and daily life, raising legal questions and debates. This book explores a key issue at the intersection of law and technology: Decentralized Autonomous Organization (“DAO”). Specifically, it examines the relationship between DAOs and traditional company law across jurisdictions. The book is structured into three chapters. The first introduces blockchain, its fundamentals, legal developments, and key concepts. The second analyzes how Civil and Common Law frameworks apply to DAOs, along with new legal wrappers. The final chapter presents the New Code, a regulatory proposal addressing the challenges identified throughout the book.
