Ask HN: What is the state of homomorphic encryption?
Is homomorphic cryptography still academic or is it ready for production use cases? Who are the leading companies?
Other companies involved in FHE are Zama, Duality, Intel, Inpher, Cryptolab, and a handful of companies working on hardware accelerators. In my view, the one company that has a bona-fide production application is Cryptolab. As I understand it, their work is used to do private contact tracing for COVID in South Korea.
