Worth a look.
The Internet was originally designed for one thing – to allow machines to communicate with one another. As a result, machines have identities on the Internet, but people don’t. This stunts communication and trust while adding enormous complexity, costing the global economy hundreds of billions of dollars each year.
Self-Sovereign Identity (SSI) is an identity that is 100% owned and controlled by an individual or organization. No one else can read it, use it, turn it off, or take it away without its owner’s explicit consent. This simple form of identity is private, extremely secure, and goes where you go. This will enable trusted interactions to occur between individuals, institutions, and businesses.
