Identity Book



The internet was born without a native payment and identity system. The rise of the commercial internet complicated forever trust in payments and identity creating a myriad of fraud, crime and surveillance capitalism opportunities hindering the internet to fulfill its full potential. 

Self-Sovereign identity (SSI) is the technology that incorporates the cryptographic advances of cryptocurrency and blockchain technology to move to the next level to create the trust economy to benefit people, companies and governments. However, the full power of Self-Sovereign identity, can be used as all technologies in value creating driven efforts or selfish ways depending on how it will be implemented. It will be for the reader to asses while reading and learning with this book what this means for the future of the internet and the world.

What’s Inside

  • The architecture of SSI software and services
  • The technical, legal, and governance concepts behind SSI
  • How SSI affects global business industry-by-industry
  • Emerging standards for SSI
  • The larger impacts of SSI on society and the future of the Internet

Written for technology and business readers. No prior SSI, cryptography, or blockchain experience required.

Proceeds from this book will support three non-profit organizations shaping the development of SSI:
