Still quite confused: Isn't the purpose of Facebook -and all media outlets- to precisely be "unprotected"? I mean why would you put anything on Facebook if you don't want people to see it? If you want top say something to somebody and only to that somebody, you use a text message, right? Or, for more "protection" a phone call...
Of course FB isn't a wallet but if you put a text on a wallet, there's no "social" aspect to it, is there?
I guess what I mean is that if it is "social" cannot be "protected", by definition.
Encrypted messages can be used for:
- secure communication between two persons
- attaching messages/subjects to transactions (i.e. an order id, article number, or just simple "thank you")
- wallet and app developers could it use for automation tasks between two parties by sending commands via the messaging system (contracts, refunds, recurring payments and much more)
