While I am not allowed to talk too much about it, this is exactly what I'm currently working on for certain high profile companies that wish to share information (query results) between themselves, without ever actually sharing the data itself, in a way that the country-wide regulator can verify and check for anticompetitive behaviour. I'm currently having fun experimenting with homomorphic encryption, to see if I can't add another layer of "trustlessness"
