There's a few different projects that are really looking at zero knowledge proofs and specifically on things like ZK SNARKs and ZK Starks. Owen Labs is one, this is with Isaac Mecler and folks there who basically have developed an approach to scale blockchain storage using ZK SNarks. I think that right now there's just an amalgam of different initiatives that are happening formal and informal in the ecosystem. Where do we go next? Do we look at hardware or things like that? I think it's an open question for everybody and that's why everyone's so excited about it.
