Even if you have a zero-knowledge proof that "this person is at least 18" (without revealing their actual age) you still need to identify which person it is that the proof pertains to. That is the difficult part.

@kbal@fedia.io @mullvadnet@mastodon.online It's standardizing on the DID and "Verifiable Credentials". There's a lot of push to make blockchain an integral part of it but so far I think you can implement it all without it (revocation maybe not). The DID and the VCs that say stuff about it are all supposed to be self-validating. Basically you'd hand the service you're signing up for your DID doc and a VC that has your age proof in it. They'd validate the proof and check the sig on the VC. Something like that anyway.

@kbal@fedia.io @mullvadnet@mastodon.online @crazyeddie@mastodon.social this. If it was anonymous then it would also be transferrable, which would defeat the supposed purpose. It's almost as if the actual purpose is increasing surveillance capabilities 🤔
