Recently I saw a question asking if there were any social impact projects going on that were using blockchain technologies. I have no idea how blockchain technologies can apply to social impact projects; all I could come up with was verifying that my donated can of soup made it into the hands of Homeless Joe via a verifiable route, but I don't know how much I'd need that. I trust that the soup kitchen [or whatever] directly feeds people, and if I didn't I'd be volunteering up front as well or not even bother at all. Perhaps again I just haven't applied my imagination to it.
