alt Hacker NewsThe age verification proposal of the EU tries to do that, the government knows you used age verification (and I think the rough number of times you used it), but they don't know when or where you used it.

The EU passing a law about the internet? What could possibly go wrong?

I can't imagine countries with such strict speech laws, for example, would be willing to build a system that is technically incapable of linking the person visiting a sire and the site requesting verification.
This proposal may have been updated since I read it previously, so I could be wrong now, but it didn't read as a true zero-knowledge proof as key steps in the flow still required a level of trusting the government as the central authority to do the right thing and not track requests, both today and in the future.
