Identity On-Chain: Own Your Digital Self

In the digital world, identity has become fragmented, monetized, and controlled by centralized platforms. Identity On-Chain: Own Your Digital Self explores how blockchain enables individuals to reclaim ownership of their digital identity and participate online with greater autonomy and trust.
This book examines how on-chain identity shifts control from platforms to users, enabling self-sovereign identity models that are portable, verifiable, and privacy-preserving. It explains how decentralized identifiers, credentials, and wallets can replace repeated logins, data silos, and opaque verification processes. Rather than focusing on hype, the book emphasizes practical identity use cases that work across ecosystems.
Inside this book, readers will learn:
• Why digital identity is broken in today’s internet
• How on-chain identity enables user ownership and control
• How verification can exist without constant data exposure
• How identity supports access, reputation, and coordination
• How identity layers unlock Web3 adoption at scale
Written in a clear, forward-looking, and user-centric style, this book is ideal for builders, policymakers, product designers, and Web3 professionals. Identity On-Chain offers a practical roadmap for creating digital systems where individuals truly own their digital selves.
