The Path to Self-Sovereign Identity

Entrepreneur and technologist, Christopher Allen, provides an overview of self-sovereign identity and the evolutionary steps within online identity that led to the concept’s development

Published in 2016, Christopher Allen outlines the path that brought us to the concept of self-sovereign identity (SSI), a system that enables individuals to have genuine ownership of their official identities and ultimate control of how their data is stored and shared. 

Allen lays out the four models of online identity, including centralized identity, federated identity, user-centric identity, and self-sovereign identity.

He goes on to define and outline 10 key principles of SSI: user-centricity, control, access, transparency, longevity, portability, interoperability, consent, minimized data disclosure, and protection.  

Allen’s post is a valuable reference point and introduction to SSI, defining what it is, how it should be regulated, and how it might evolve.
