So, that's not anonymous then. Because it allows tracking across multiple accounts, some of which are associated with your name. An unchanging proof of age is pretty much just another name for a government ID number.
Not necessarily. In theory, the attestation that someone is of age can be provided by a central service. The central service does not need the website account information to provide a non-fungible certificate, that you show to your service that has no way of knowing who you are from the certificate. All it needs to ensure is the certificate is used only once per account.
You can then prevent certificate forging by forwarding a cryptographic hash of the requester identity (generated by the website client), which will be included in the cert body so the website can verify the attestation was generated for this specific request, and it cannot be randomly reused.
Of course this doesn't solve the problem of using your grandma's id to bypass age restrictions, but I think that problem is worth the cost of privacy gains from corporations not validating IDs directly and screwing up like Discord's vendor did here.
Grandpa isn't interested in Discord, so you can open a second account using his Proof of Age. Maybe a third account, using Uncle Ned's. And a fourth account, using...
I think I'm fine with that tradeoff between effectiveness of age gating vs privacy gains of not having IDs sent over to corporations. To me, identity theft by targeting large stores of government IDs, is orders of magnitude worse than a teenager accessing NSFW channels every now and then.
I'm not defending age verification's existence in the first place btw, I don't think it's a good idea without secure protocols of central attestation for such things. But of course, governments aren't interested in solving the harder more valuable problem, they're interested in shifting the responsibility to corporations while crying foul.
Surely that's solved easily by ensuring a 1:1 association between the proof of age and account?
