 Ah, really looking forward to watch this jazz session with Togeta with Anjido. Ah, too bad, seems like he can't make it. Ah, now I have to spare ticket when I'm going to do with it. Well, let's see if there's someone in the queue who still hasn't got a ticket and maybe they'll buy it. I have a ticket. Anyone wants to buy a ticket? Hmm, spare ticket here. I would really like to have a ticket. Now it's all sold out and I didn't get a ticket. But hey, you still have one available? Yeah, yeah, I do, I do. My friend cancelled and he can't make it. Okay, great. What do you want for it? What about say like 35 euro? Okay, that sounds good. Perfect. So here's the ticket. Let me just basically scan your QR code. Here's my code. Okay, so just click on sell ticket and I'm going to scan your QR code. Oh, perfect. Ownership of the ticket will be transferred. Thank you very much. So finally I can get into the concert. How do I know that he sold me a valid ticket and not a copied one? Oh, when he scanned my QR code his phone was sending a transaction to the blockchain which then responded to me with a confirmation. The blockchain ensures that the ticket is valid and cannot be copied. And I have to check your ticket. Yeah, here's my QR code. Yes, the ticket is valid and your concert. Thank you very much.
