One of the most advanced solurions I am aware of is GET protocol. Guys are not only partnered with Klaitn (Google it, very famous korean platform), but also is main ticketing partner of Oerrock festival. And talking more on current progress, they have already sold around 300k tickets. This is a truly great result, from my point of view. And they grow truly fast
Hmm, indeed sounds pretty impressing, let me have a closer look at what the guys are offering and get back with own thoughts, thanks for your recommendation
