Homomorphic Encryption is a modern way of encryption that allows one to run algorithms on encrypted data without first decrypting it. We give an overview of the technology, discuss its many flavors and compare it with related privacy-enhancing technologies. Any feedback is welcome!
Not sure what's the value prop in this case...
HE is known for having very low performance for basic operations (at least for existing OSS implementations).
Is there any breakthrough or it's just a commercialization of existing tech?
At Pyte, we don't use HE, but rather a related but much more practical primitive (Secure Multi-Party Computation, SMPC). However, this survey post meant to be merely educational, since HE is a very fascinating paradigm (but I agree, in the present form it is impractical and will be for the foreseeable future).
