    The way it’s imposed on the fediverse is bad, but I like this part:

    The Blueprint is open source and uses zero-knowledge proofs: cryptographic methods that prove a statement like “over 15” without revealing the underlying data. Each member state must provide at least one such solution free of charge to its citizens.

      How often can I probe it? If I can establish you are over 15 but under 17… I know you are 16 (squeeze theorem or something)

        It’s not clear but it seems like the service is restricted to the same age ranges it asks anyone, so it couldn’t do that as effectively. Although it could just use when the user passes from one category from another to get their age, at least if the account was created when the user was >18, but that seems unavoidable.
