These are excellent questions. I often ask Google researchers, "How Deep is the Mind?" They don't seem to know. You see, it all comes down to democratizing the blockchain, and the only way to do that is with AI in each and everyone's hands. Together, we can make a more open AI, for everyone! And for you too! The only trust required for CryptoMinds is trust in proof of work, am I right?
In specific the field of homomorphic encryption. It's a somewhat new field. Some libraries and methods require hours per bit operation, whereas OpenMined and PySift are claiming to do similar things with orders of magnitude less overhead.
I ask because if their claims are valid they are doing some very interesting things.
