 Thank you very much. When I came here this morning, I wasn't aware that I'm going to give a quick talk presentation So thank you very much for the opportunity to talk a little bit about What is code and what code has to do with with blockchain and blockchain research. So I'm Peter I recently joined Code University of Applied Sciences. We are a Private state accredited University of Applied Sciences about 500 meters from here into that direction 400 students free study programs software engineering product management interaction design and Part of my new job is also to cultivate and to build Blockchain from an educational perspective before I was a post-doctoral researcher at Technische Universität Berlin and Telekom Innovation Laboratories also here in Berlin doing blockchain analytics And in case if you haven't heard about code before Code is basically trying to do a lot of things New and better when it comes to education. It's about self-directed project-based learning in interdisciplinary teams and Code is also very deeply embedded into the Berlin ecosystem Companies so that students basically can choose their own problems Working on them and we the professors are more acting like mentors or consultants to the students and helping them learn along the way And what I would like to do in the next few minutes is to Introduce you to some of the work I also did in the past and I'm currently working on one example is called the token gallery You can also open this in a browser and this is an example for an analysis of Token transfers on blockchains and here you can see visualization of about thousand different token networks in which we can Observe different transactional patterns where Tokens are being transferred between different addresses some of these tokens are being traded on major exchanges and by just Browsing through this list. You can go already just by looking at these patterns guess That tokens different tokens are being used in different ways somehow We can see some I mean obvious patterns like this. This is probably a failed airdrop So not a lot of activity here. We can see some fractal patterns down here. They typically come with Burning token somehow we can see some quite Obvious structures Maybe over here what we have one big exchange involved and we have a couple of Bigger hub and spoke patterns But there are also some patterns that can't really be explained so far So if you're interested and want to learn more about this go to token gallery net And you can yeah, basically find find more at this website now I just wanted to point out that when it comes to analyzing token networks nowadays That it is first of all fascinating. I mean, this is very nice very colorful But also if we went more deeply into the network and the graph theory behind we would find that many of these structures Very new We haven't seen them before if you do social network analysis if you look into communication networks If you look into transportation networks the structures in these graphs are different and These are new patterns that we can now see emerging from the usage of tokens on blockchains And no matter whether this is about for example a token that is used to play poker online Or someone deploying a test smart contract on on the blockchain Or again a failed airdrop over here These are all new patterns and that is from a research sector of course fascinating to Analyze and to observe first of all, but it is also interesting maybe for future applications to look into how Tokens are actually being used and what we can learn from these patterns Yeah, there are many of these Visualizations available just feel free to go there and look look around and a second topic I would like to very briefly mention is also the topic of blockchain governance and here you can see a recent visualization where Atom tokens on the on the cosmos blockchain are being delegated by the token holders to validators so that these validators can to it can take the delegated tokens and then get elected to create new blocks on the blockchain and By just looking at this again. This is just a high-level visualization But we can first of all apologize for the low resolution. It's I think better if you go online later on But you can already see that in time there are some burst events where massive redelegation of tokens happen at some point in time in indicated by blue lines now Probably this was some real-world event happening many people reconsidered their delegations And this is of course also interesting if you ask who's actually in charge Who's actually in control of a blockchain if you look into token delegations redelegations proxy votes and the ultimate question who is controlling the blockchain so these are questions We are we are currently Dealing with we are we are looking into analyzing these networks And I'm basically here today to say that you are welcome to join this discussion If you're interested in these topics and the last thing I would like to briefly mention is That there is also a conference upcoming which I'm one of the organizers. It's I triple edeps It's gonna take place in April and Oxford UK next year. It's a second edition of an conference on decentralized application and the submission deadline is the end of this month So if you have something as some ongoing work, you would like to submit your very welcome and hopefully See you in Oxford. These are my coordinates and Feel free to contact me if you like I'm also be around Only today unfortunately not tomorrow and now I'm open for a couple of questions. Thank you very much Yeah, have you tried to apply any like your like token governments model within a quarter University Within within quote Berlin Well, one of the ideas is now to build some environments and some structures at code First of all to make students able to quickly learn about these concepts But we are also thinking currently about what kind of processes we could possibly Integrate and enrich we are by means of DLT's To the best of my knowledge. No decision has been made yet, but we are actively thinking about it Thank you. How do you know that the air drops failed? Because the tombs didn't move or because there was no usage anymore at some point in time. So basically usage was was dead Okay, thank you very much
