Both of which famously keep databases of everyone’s IDs, and require transmitting your ID over who-knows-what network to who-knows-where.
Scanning ID’s into a database is a thing. It’s not everywhere, but I have seen places do it. Usually Hospital’s and Casinos
Right, and such a solution will ultimately just require everyone to trust the fact that it’s been “done privately and securely”
No, that is not true. It is possible to set it up with zero trust, so we do not have to trust them. It will be setup properly in the first place. It’s like the fact that Bitwarden can be open source and yet people can’t just decrypt vaults despite everyone having access to the code. Zero-knowledge proofs can be done without requiring us to trust anyone. That is what I have been saying, but it keeps seeming to be skipped over. There would be an initial proof with a government identification (which basically everyone already has) and from there the system could be setup in a way that you can prove you are over the age without them knowing literally anything about you. It is possible to prove you are over 18 without them even know your age (other than it is greater than or equal to 18)
