Bank? So now you know what bank they use?

This is why you have a relay in the middle.

Then, Chase knows you've verified your ID somewhere, the relay knows that some Chase user verified themselves at Pornhub, and Pornhub knows that the user is over 18, without knowing their identity or what bank they're using.

You could also do this with ZKPs and device integrity protection. The latter is more secure but more complex, the former is much simpler and openness friendly.

		> You could also do this with ZKPs and device integrity protection. How has the anti-competitive lock-in scam of "device integrity protection" entered the discussion? Using ZK proofs without it has exactly the same effect. There are far too many attestation-passing insecure devices to expect attestation to have any security value against attackers who can choose any of those devices on purpose.

		Or we could use multiple relays so nobody knows both the bank and the purpose, or even who would know the other piece of data... and now thats just Tor but for identity verification. Might be a good idea actually, except the whole point is Anthropic wants to know who you are.

I think the key here is “a trusted third party” more than “bank”.

Also, I’d rather a company know “he has an account at Bank of America” than “His full government name is Bit Masher and his driving license number is 9”

Well, they already know your credit card issuer, it's not that wild. Really Visa/MasterCard should offer age verification on their network... They have all the necessary components.
