> Obviously this will not just be stored on your phone. There will be a backend database of all issued IDs. Which will then serve as an authoritative identity system for unifying government databases. Incorrect, that isn't the proposed system at all. In fact, Government is kept out of the loop, except as a reference. You seem not to understand what the IDs are, so I'll try again to explain their form. The wallet (the app) holds data that you enter. A datum might be your name or national insurance number, citizenship etc. These are verified individually by the verification service and it returns each one with a cryptographic signature. The 'ID' is then a container for proofs. It exists only on your phone. It's totally disposable. Delete a container and you can regenerate it. And you'll have more than one, many more in fact, for all different uses. Each will have a different selection of attributes and their signatures. The IDs never exist anywhere else other than on your phone. There's no database of IDs, and the app has no contact itself with the government API. Representing it in any other way is a fundamental misunderstanding of the proposal. The proposed format simply doesn't work the way you claim.
