Disclaimer: I am quite biased as I work for the company pushing the innovation.
The ticketing market for events is quite broken in my opinion, and for the traditional infrastructure, it is a very problem to solve. The only way you can prevent people from reselling their ticket at this point is by putting the ticket on someone's name. But this obviously has some problems associated with it, as type of verification at the entrance of the event is very time consuming.
The company I work for has built a ticketing system that does ticket registrations on the blockchain, and by a 'smart' way of delivering the ticket (not to a PDF but to the users phone browser) the ticket becomes dynamic and thus impossible to resell. I have to go now, but if anyone is interested here is the link to the whitepaper:
