True privacy blockchains are impossible. Monero, which is supposed to be private and anonymous, can be tracked, although it is very difficult. The nature of blockchains is that. I won’t say a solution is impossible, but Hive is too small and our dev resources are scarce to invest in such advanced research and development.
We need more devs and more documentation to enable people to do research and development. Right now sadly only a few people have the know-how to do that, if we had more people then someone could go on that tangent
