It is going to take a while for the world to understand the benefits that zero knowledge proofs offer in terms of privacy, but they are starting to be found everywhere, and privacy advocates (of which I consider myself one) need to understand what they offer to the consumer in exchange for some real benefits that we…
Zk proofs have nothing to do with Snowden’s criticism. They’re collecting and storing iris hashes regardless of whether they’re using Zk proofs downstream in their tech stack.
