“And then the second thing we do is we separate all of this from you with a zero knowledge proof. So meaning you have that secret on your phone. But no one else has it. No server has it. We don't have it. And then you can later go back to this multi-party computation and say like, hey, I have a secret that is part of that computation and I am in fact unique. And you can prove that to a platform. You could go to the social network and prove that you're a unique user to the social platform without us knowing anything about you or the social network knowing anything about you.”

“And how we approach that is we have multi-party computation. And so that essentially means that, so in our case, when you verify with an orb. You know, we take all these pictures they get computed on the device, and then they actually get split up in multiple …”
Blania: Photorealistic real-time deepfakes will be commoditized by 2027
“And so I think, you know, in a year from now, it's just going to be a full commodity and it's going to be super photorealistic and absolutely real time.”
Blania: Verified human identity networks will exhibit powerful network effects
“In a world of AI, having a human network is going to be this incredibly important thing. And so actually, yeah, two things like one, you will need a proof of human, but then second, it will have very strong network effects.”
Blania: Social platforms will fail attempting phone face biometrics for human verification
“My guess is over the next couple months, we will see things like these platforms trying to use things like face biometrics on the phone, which, you know, I know it will break, so it's fine, but I think we'll go through that cycle now.”
