first things first. I think the maidsafe-attempt to decentralize data before decentralizing computing is more promising. - interesting idea anyway.
I still think there are lots of outstanding questions here, though to be honest I haven’t researched them in depth. I think in an ideal world, something like Zennet would use solid homomorphic encryption, so “hosters” could have zero knowledge of the computations being carried out.
Agreed, but I think zkSNARK computing is likely to be a better option.
