What do you think about Decentralized Identity (DIDs - https://www.w3.org/TR/did-core/)? With it, you can have several identities and easily generate new ones when needed (but you probably need to have a single, government-recognized identity for the real world).

Europe seems to be working hard on establishing an identity for every citizen: https://commission.europa.eu/strategy-and-policy/priorities-... (most countries already have that, but this is about unifying the various countries' ID systems).

Unfortunately no purely technical solution works. As I've said in the end of my article:

> We need to support the case when a person wakes but-naked in a corn field, suffering from complete amnesia, and remembering nothing about himself. Today, such a person has a chance of getting his identity back, but in a pure technological world, "the computor just says no!"

Regarding the various European ID initiatives: they might seem a good idea, but they don't actually work in practice: for better or worse, our internet solutions seem to have settled on email as the de-facto identification system. Are any of these EU ID initiatives completely interoperable with the email system? If not, they are useful only for purely official interactions with the government, and solve nothing outside of that realm.

Also, because most such ID initiatives are actually X.509 tokens that work solely on Windows, with Adobe products, they are beyond useless...

(Let alone that one costs ~50 EUR per year in my country, Romania...)

I am sorry to be blunt but you seem to be misinformed.

DIDs can have a controller, and the controller can be your "real-world" identity... If that is government-issued, you can recover it the same way you recover your identity today in case you lose all your documents. After that, you regain control of all your other DIDs (which you keep to ensure anonimity, e.g. you can have a different DID for each service you sign up with).

That's plain wrong. It's already possible to use DIDs to sign up with any business you want, though admidetly as the specs are still in flow, there's no much out there other than lots of PoCs - but those already show it's absolutely possible and desirable to use DIDs instead of email addresses... private accounts are an actual liability for most businesses (except those selling your data for marketing purposes, of course).

> Also, because most such ID initiatives are actually X.509 tokens

Where did you get that impression?? There are several DID methods and the most popular so far have nothing to do with X.509 certificates (I think that's what you meant by "token"?). Many are using JWKs (JSON Web Keys) as most alternative solutions do. Check the current registry of DIDs here: https://www.w3.org/TR/did-spec-registries/#did-methods

The EU seem to be using both Web DIDs (no blockchain) and [EBSI](https://ec.europa.eu/digital-building-blocks/wikis/display/E...) (EU blockchain initiative).
