This is my #1 pick for a hidden gem in all of cryptos. I think Secure Multiparty Computation has been waiting since the 90's for the right use case and this group at MIT has been thinking about this for many years. Having spent a lot of time working in the authentication space, I think not having to store user's private data while building an application is a monumental achievement and can systematically change the way companies build applications. I LOVE that they've already launched the Catalyst platform too, to prove that they don't just have their heads in the clouds and they can actually deliver something. I'm a huge fan of this project
