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.
