Riley Hughes and I recently had a conversation about the question "why doesn't SSI exist already?" There is also an emerging Self-Sovereign Identity (SSI) metasystem based on DIDs and verifiable credentials. The SSI Metasystem, on the other hand, meets all of Cameron’s Laws.

Summary: An SSI wallet provides a place for people to stand in the digital realm. Last week, Doc Searls posted What SSI Needs where he recalls how the graphical web browser was the catalyst for making the web real. The SSI wallet Doc is discussing is the tool people use to operationalize their digital relationships.

This post gives and introduction to SSI and IoT. The follow-on post goes deeper into what a true Internet of Things founded on SSI can provide. But I left out things because I hadn't yet provided a foundational discussion of DIDComm-enabled digital relationships that's necessary to really understand how SSI can transform IoT.

From time to time, I run across the idea that self-sovereign identity (SSI) systems like Sovrin are necessarily self-asserted. This is the myth: that SSI means that the person gets to say anything they want and the relying party just has to accept it. This is NOT what SSI means.

Summary: If your identity system doesn't use DIDs and verifiable credentials in a way that gives participants autonomy and freedom from intervening administrative authorities, then it's not SSI. I think we've arrived at a place where it's possible to put some stakes in the ground about what SSI is and get broad consensus about it.

SSI doesn't have accounts, it has relationships and credentials. Kamea, a member of the Sovrin Telegram channel asked this question: I’m looking for our users to sign up with a Sovrin account, validate their identity, then use it to verify age and passport country on our network using a zk proof so we don’t have to handle any personal data.

SSI provides improved support for creating, managing, and using digital relationships. The most problematic word in the term Self-Sovereign Identity (SSI) isn't "sovereign" but "identity" because whenever you start discussing identity, the conversation is rife with unspoken assumptions.
