What is their approach to biometrics with blockchain? Do they just dump your data on the blockchain for everyone to see, like Bitcoin? You would assume it is at least hashed.

Or is it encrypted so that only someone with the corresponding key can use it to prove your identiy? In this scenario they couldn’t verify your identity without your consent. But also then you would always have your key with you at all times, so I doubt they went this route.

It’s probably just hashed and public, is it?
