I'd like some of the experienced Graphene developer wizards to comment on this, whether to confirm or deny my conclusion, or just for sake of discussion.
Whether it's possible on Graphene I do not know for certain, but I do think it will be possible on Enigma and Enigma promises secure multiparty computation on a blockchain. Whether or not they pull off their theoretical claims will depend on the code which so far hasn't been shown.
Even if they were to pull it off, I don't know if privacy would work along with having secure identity.
Hi @dana-edwards , while I can't answer this question but I've trying to find a way to contact you but nowhere to be found on steemit.chat, what's the best way to get in touch with you, at least with something more realtime than in this comment section? :)
