 Okay, so I hope you're all having a nice lunch. So I will do a small quick Lightning talk here as well, and I'm very nicely following the trail We already have with those blocks perks topic and artifact topic and proof of existence topics. So We have a similar thing. That's also leveraging blocks perk as a kind of proof of concept small technology thingy and Our idea was to just have a small easy integration with mudlap with mudlap the scientific programming environment and existing environment many scientist researchers Are using and we just thought okay How how might this proof of concept look like and would people be interested to use it and incorporate it in their existing workflows Yes, I'm here together with Dominic. He's sitting there and We did this small thing together and we are both from the Institute for Internet Security It's an institute at the Westphalian University of Applied Sciences here in Germany in Gelsen-Kirchen and I'm leading the blocks at blockchain a research group there and we do all kinds of blockchain related projects So I will skip most of the more theoretical background stuff since we heard a lot of odd So we want to implement a proof of existence use case on the blocks perk infrastructure. That's the basic idea Of course, there is a history to it There are certain publications talking about possible use cases in the scientific field where one might use such a proof of existence service And the blocks perk stuff. I can also just jump over it. And yeah, that's that's basically It's the architecture of the implementation pretty pretty simple. So the idea is you have Existing matlab projects on mudlap code, then you are using our small mud lab library We are providing and this library will perform HTTP calls to the blocks perk rest API And this is already has been deployed by the blocks perk team by the blocks work infrastructure And this rest API is then interacting with the smart contract in the blocks perk network to perform the actual proof of existence stuff and From a usability perspective, it's also pretty simple send since this Rest API service is loaded with a full wallet. So it's doing the transactions for you. You don't need your own wallet You don't need any any tokens and so on. So it's for any users. It's just like using any other basic web service All right, okay, and this is then how it would look in the actual Source code. So we are we are not really mudlap developers So if there are any mudlap developers users here and they would say all the Ideomatic way of mudlap to build such an API would look like this. We would be very happy about feedback, but This was just the idea to have have some capabilities to directly integrate those proof of existence call Use case into our actual research source code So just you can certify any any kind of data from within your mudlap source code Right now it would be any kind of file So maybe you had to have it one point some intermediary results or whatever some mudlap result file Then you would just call it in the certify data function Of course ideally we would do Something more complex where we would also certify the current state of the Mudlap project with also the source code This would be a nicer approach, but right now it's just this easy proof of Concept and we would be interested to see if people have any interest whatsoever to use something like this And yeah, it's free to use it's running on the Blocksburg infrastructure. So there is there's no Yeah, no big investment to just try out to use it and Yes, we just push it to to github It's open source under MIT license and anyone can check it out try it out Yeah, thank you very much Of course if there are any questions you can also later come talk with me or maybe some mudlap lovers here who directly say Yeah So our code Maybe it would work with canoe octav not sure So I'm not not a big in them in the matlab community, but we are having some Java code actually that does it since from Mudlap you can directly use Java. So if it is a mudlap an open mudlap implementation It would directly work as a drop in but also since the actual Implementation is so small you can so easily do the same thing in any other programming environment or programming language because in the end It's just an HTTP call since the rest API is already there. Thank you very much
