Nah, much easier solution: digital tickets that you can't sell. Ticketmaster could do this easily, their tickets are a rotating code (like an RSA key) so you can only sell a digital ticket either a) with their permission or b) by giving the stranger to whom you sold it your ticketmaster log-in creds. The latter is pretty easy to stop, you could easily make it unfeasible for scalpers to create accounts, buy a ticket, then give the account away over and over.
