 Thank you. So, for those who have the program book, I'm sorry I made a typo there. It's not, I said I wrote it as not be but free, but it's supposedly not free but free. Yesterday I was drunk so I made a mistake. So, it's kind of dangerous to drink alcohol. So, is there anyone who loves vodka here? Please raise your hand. So, anyone who don't? Okay. So, if you're into vodka, I'm sorry about that because I'm gonna insult it a bit. So, according to my watch here, it's 8, around 8, so it's time to drink some alcohol. Maybe anyone already drank. So, it's vodka time in the world like Trump likes vodka. He made it, he's on. So, people think vodka is a solution when people drink it. So, when people drink vodka, people think it's the solution or maybe vodka is the answer but you don't know what the question is. So, when you drink vodka, when vodka is fine, to vodka, I don't know, 3, 4, 5, then you may say blockchain, blockchain. So, if you support vodka, maybe you support Russian Federation and maybe some bad hackers as well. So, why not vodka? Here's the deal. So, again, I'm talking about blockchain things. So, why not 3 but B? So, instead of 3, 4, 4, 5, we're talking about blockchain-based stuff. Anyone from Slovakia? No one? Oh. I certainly found that vodka also means that some punctuation in Slovak. I wanted to be, our protocol is about dynamic key agreement. So, we want to be some punctuation of the dynamic key agreement in finally. So, we hope so. And here's the boring stuff. So, from the original 3-like approach, when some people behave maliciously, then whole process might be in danger. So, instead, we are approaching all approaches using the direct-to-disk graph. We use, again, blockchain here. Yeah, that's it. And for further discussions, contact me or our supervisor,
