 We have to understand exactly the problems that are in the area. So, if you want in this big design space, it's just one specific protocol. How can we make it better? Which means faster while keeping it secure. In order to be able to do that, we have to start from basic principles. And the good thing is that computer science right now is quite mature. In terms of being able to precise, define problems and their properties. It's just that, and I'm talking and I'm saying this both based on my own research and in that interaction with people that are actually working in computer science and trying to formalize problems. Bitcoin is actually quite interesting to formalize because it's even from a completely theoretical point of view, it looks at problems that we looked at for many years and it looks at them from a different point of view. So, this by itself is fascinating from also a theory point of view, not just a sort of real world practical point of view. So, yeah, I would expect like a lot of very nice research also in theory to be motivated by what Bitcoin does. And that would be like in game theory, that would be like in distributed systems and in cryptography. My hope is that Greece would be a tremendous place to actually try cryptocurrencies. That would be, but I have to say also at the same time that a lot of a lot of people in Greece, they're still like quite behind from adopting or be willing to experiment. I mean, and it's sad to say that in many aspects like Greek society is still quite conservative and I really do hope that actually with events like that that do happen in Greece and they bring like a lot of people that are at the cutting edge of research in Bitcoin, like we will inseminate the area and the students that are attending like will actually be the sort of the carriers of these new ideas like in Greek society.
