The digital revolution has introduced new dimensions to ownership and security, challenging traditional notions and practices. Cryptocurrencies, decentralized networks, and digital identities are just the beginning of this shift, bringing with them unprecedented opportunities and challenges for securing and managing our assets.

As we stand on the brink of this transformation, it is not enough to simply adapt to these changes; we must actively engage with them, rethinking and redefining what self-custody means in this new context. The essence of self-custody—autonomy, security, and control—remains unchanged, but the ways in which we achieve and maintain these principles are evolving. This evolution demands a fresh perspective, one that acknowledges the complexities of the modern world while staying rooted in the timeless human need for self-sovereignty.

This book aims to provide a mental model to help you approach and navigate the coming world of self-custody. It offers a framework for understanding the underlying principles of self-custody and applying them to the new realities of our digital age. By exploring the intersections of technology, ownership, and human relationships, this book will equip you with the tools to confidently engage with the challenges and opportunities that lie ahead. Whether you are managing digital assets, building new forms of social organization, or simply seeking to understand the changing landscape of ownership, this book will guide you in making informed and empowered decisions about your role in this evolving world.
