 I mean, I'd heard of Bitcoin before, obviously, but it was not something I'd really looked at that much. But at that time, I read the Bitcoin White Paper the first time. And my first reaction to reading it was this is, as a technology, very interesting and really financial transaction seems not to do it justice as a technology. I was mainly at that point interested in censorship resistance, so how I could use it as a technology to build, for instance, a discussion platform which was not controlled by any one entity. So that's, at that point, I sort of mostly left it and went on with my studies until my final year, I saw as one of the project proposals that Agilos was doing something with smart contracts in Ethereum and I thought that's rather interesting. From the financial perspective, we have seen it expand in a very dramatic way the last couple of years. But from the application of the blockchain technology, we haven't seen that much expansion. So I think that the level that the technology is used and the financial depiction that we have on the markets don't follow, one doesn't follow the other. So I think that in the following years we'll see the use of blockchains as a technology expand compared to what we have seen so far. So when I started to study mathematics in 18 years old, I liked that mathematics were very well defined. You had a problem, you had a solution or very clear, but the bad thing it was that I hadn't seen many applications of mathematics during my undergrad degree and when I started my MS in computer science, we had some cryptography lessons and so on and I started to see that mathematics were very related with cryptography and more applied things and I had of course four blocks in technology and I was very curious how we can combine mathematics in a more applied way in order to use it as a tool, not as a purpose, as a tool in order to prove something that is a problem in the research area that can give a practical solution and so on. The real world applications, the two things I think which are the most important flaws in the systems we have right now which I think need to be addressed is the first one is scalability and the systems we have right now deal with pitter-fly small amounts of data really, as in I think the Ethereum blockchain right now is a few hundred gigabytes out of the world working on it for years, which is, it's terrifying to download it but it's also terrifyingly small when you consider this is all that has gone on worldwide and we need to figure out a way to be able to handle more data. And the second one is privacy and the fact that blockchains with few exceptions are essentially purely public is a very limiting factor for many applications and it's something that must be removed, it's what my research right now is mainly focused on. The benefits of being in the blockchain lab are that people from different backgrounds can exchange knowledge and ideas and they can have different opinions so it helps them to see certain problems from different angles. The University of Edinburgh is one of the oldest institutions in Great Britain and in Europe and it is interesting to see such an institution follow and comply with the new advances in technology. So in that way it is very, it is interesting to be part of a community that is also that brings the history with it and also uses it in order to promote the new advances in technology. It's a very nice environment and then we have essentially the freedom to do research into whatever we want. I mean there are caveats of course but for the most part as long as our research direction is interesting and doesn't seem doomed to failure we are fine to do what we want and it's nice to interact and be in the same room with people who are very talented and working on not the same thing but very closely related things so that they can see the problems you're having and that you can also appreciate the problems they're having and see in some sense a larger picture of things crystallizing at Fiddle. Our research is targets problems that actually have impact in the community and in some cases might also have some industrial applications so in that way our research follows the academic criteria in terms of how rigorously we do our work but also we target problems that actually have some real implications in the community. In general one of the things that drew me to doing a PhD and also draws me to blockchain is that it's essentially a system for the public good and I think that working on it to put it in very high and mighty times is for the good of all. Where I do that I don't really care I think as a model it's better suited for academia than for a business in principle but if a business is working for the public good then I don't really mind.
