- The DID is a part of the area now know as Decentralized Identifiers.
- Distributed ID is a somewhat different concept from Decentralized ID in that it envisions an identity which is broken into may pieces that are hosted by many different authorities and only brought together in a Relying Party upon User Consent.
- The current paradigm in open identity is for each conforming Relying Party to provide a list of Identifier or Attribute Providers that the User could chose from to allow access.
- In this model it was up to the Relying Party to establish a link and share a secret with the Identifier or Attribute Provider in advance of any transactions.
- It also required the user to pre-register with one or more of those providers, typically one of the big social sites, like: Google, Microsoft or Facebook.
- The current most common protocol for some sort of a Distributed Identity was OpenID Connect which included Self-issued Identifier, but that concept never succeeded in the marketplace. It could certainly be revived in the context of a Decentralized ID.
- Now new organizations believe that they can succeed where the OpenID foundation and all of the other standards effort have failed.
- Every one knows the problem with identities on the internet. They are not under the control of users, who are extremely interested in their own Identity and want their own Privacy.
- The BHAG (big hairy audacious goal) is the user in control, when the user really doesn't want to control their identity any more than than they want to program their own computers.
- The One big problem with the existing solution of relying on social networks is that they control, and can remove, your identifiers at their sole discretion. Or in their own words:
Yahoo may, without telling you
- immediately cancel or limit your access to your Yahoo accounts, certain Yahoo Services and any associated email addresses...
- If you violate the letter or spirit of this Statement, or otherwise create risk or possible legal exposure for us, we can stop providing all or part of Facebook to you.
- We reserve the right to modify or terminate the Service or your access to the Service for any reason, without notice, at any time, and without liability to you [Instagram]
- The W3C has established a credential group (CG) to establish the consensus needed to propose a draft standard for the DID - Decentralized ID, and also a Verifiable Claims WG.
- Verified Claim is one of the work efforts of the CG.
- In this wiki the IAP (Identifier or Attribute Provider) supply a Data Category only when that category has User Consent. To get all of those categories that the Relying Party requires, the request needs to go to a User Agent that is able to release the data held across many providers, some of the Hundred Points of Light that apply to the real-world User, but only those appropriate for the Relying Party request are enabled by the user.
- The DID Method Registry has been created to track the methods that implement the DID spec. There seem to be no particular criteria for a method to be accepted other than a willingness of the method's authors to submit the method as compliant.
- Self-sovereign identities seem to be the answer to all parties' concerns.  The only problem with it that I can see is that no one seems to know exactly what it is or how it might work. MIT has started an open source effort to build something but no one seems to know what.
- Side tree protocol provides a high transaction through-put capability for DIDs.
- The Ion ID is a variant of the DID that is based on the side tree protocol.
- Trusted Identifiers are a variant of the Decentralized ID that enables Identifier Recovery as would be required for many real-world scenarios like Health Care.

- Phil Windley has created a model based on DIDs and Verified Credential that is very ambitious, but without sufficient detail to make a deployment feasible.
- W3C Workshop on Strong Authentication and Identity (2018-12-10) Location Microsoft Building 27, Redmond, WA had almost no presentations on strong authentication but lots about the DID.
- Use Case 21 and over with proof of presence was the one strong auth presentation given at the strong identity workshop (2018-12-11).
- The DIF web site has a lot of supporting documentation for the DID.
