Trust, Blockchains, and Self-Soveriegn Identity

Published on

This talk discusses sovereignty as a foundational model for a new kind of identity system that not only establishes all entities as peers, but also provides the means of using verifiable claims to build trustworthy relationships. A self-soversign identity system with verifiable claims provides increased privacy and control for individuals, more transparent consent, opens new opportunities for relying parties and third party claims providers, and reduces or eliminates integration costs while making systems simpler.
