I'm another old guy. But what about a phone app? I teach college and my students try to do everything (from research to term papers) on their phones.
One of our ideas is a mobile wallet which works like Venmo, meaning it has all potential to become viral and it would solve the identity registration issue as you get funds upfront from a friend.
People would be able to send bitUSD via a mobile app to any phone number. That phone number would receive an SMS with a link telling them that they received X amount of bitUSD from their friend and that they need to download the wallet app to access them. Part of the sent funds would be used to register the user's identity on the blockchain.
This would be just as viral as viber, whatsup, venmo, etc as it uses the same viral vector. Furthermore it could be just as disruptive to global remittance as whatsup and Viber are to the international sms/phonecall business.
Would there be any interest in the community for such an app at this stage?
