 So, welcome everybody, my name is Lefteris, I will be presenting the Paradox of Centralized Tools, we are coming for the Centralized Finals, it's a very big title, but an interesting topic. So, first of all about myself, if you don't know me, I'm Lefteris, I have been in Ethereum since 2014, I worked on Solidity and the C++ client, then worked a bit on Slokit, then I've been working in Ryden as a core developer and at the same time I have made a lot of key for the Ryden Accounting software. The talk will not be technical, it will be presenting essentially this paradox of what I see as a paradox that we use Centralized Tools to do accounting for our decentralized world. I will try to underline what the reasons for this may be, present solutions in the way forward and then towards the end of the year on the one solution that I'm biased towards, which is a root key, the application of one word. So what's the problem? Probably everyone here has done it before, like you have people discovered on multiple accounts or multiple projects, you trade in crypto exchanges, you may be gold-paying, you trade in crypto, you may be playing around with DeFi, you may even mind, and then at some point you need to find out where is what, maybe you need to get your private keys, see how much profit you made, how much you lost. So I guess you would just go to Google and start Googling crypto accountants of the following trading and you would get some solutions like this. This is a tweet by Paul Berg, which happened last month, and we have here a list of various accounting solutions for crypto. Here is an overlay of the same tweet with what I see as the problem, since everything in there is a Centralized Tools as a solution, except for the one we're not talking about today and two more, actually one is not here, I discovered it after the tweet. I say it as something bad, but I would like to analyze why, it's not just because the word is analyzed as a bad meaning, it depends, for some things it's good, for some things it's not the best fit. It performs the taxes and then you configure the software accordingly. I just learned yesterday that for the American users the IIS made a pretty cool FAQ that essentially makes it very nice for you guys and it's not only FAQ live anymore, but you can minimize, so you can maximize or minimize, you can choose whatever you want. So this is something that we have to implement, it's not yet in broadcast. So there's also a premium version for those who want to support development that has graphs, so for example here is the net value over time graph, this is a digital crypto holder, who was not smart, this is the same crypto holder, it's basically a test paper, but it's essentially just the typical crypto curve, this is the asset amount, yeah, BTC, so the net value of this kind of BTC and then the amount of BTC, so this guy was smart here, he sold his BTC on the top and then started buying and started for a year. There are more charts, but I'm not going to analyze this further here, I don't know, yeah. Yes, so this is like another chart that we have distribution of your entire net value on assets, so this guy has a lot of tokens, this is the pie chart on how they are distributed. So last name is for the project, I'm a backend developer, I don't know anything about UI, so the current UI is like a combination of Zava script, jQuery, Bootstrap and some other stuff. And my friend here is basically doing a rewrite in UJS, so proper maintainable UI, thank you Kersos, and we want tighter integration with decentralized extensives and defies, so we'll probably go to start with Kaliber, Uniswap and then probably also Compound. If the project gets traction and support, probably another non-prime application is also on the horizon, and generally, if anybody of you wants something from a portfolio-driving software, please approach me, Twitter, GitHub, whatever, and give us feedback. You can try it by visiting the GitHub repository, so this is the GitHub link in this huge QR here. It opens with this one of our biggest states, so please, if you like the idea of open-source software and of owning your own data, please help us, if you know Python, I speak to UJS, we answer more than welcome, and if you are not a user who wants to try it, even if you don't like it, don't just try it and leave it, please give us feedback, valuable feedback, even if it's negative, we want to get better through this. If you like it on the other hand, open-source software needs help, so we have a premium subscription, so you can purchase premium subscription, and once you get these stats and more features as we are progressing, you also get support in the feature request, and of course premium support. For example, the Coinbase integration came through a guy who essentially just wanted Coinbase and got a premium subscription just so that he can get Coinbase integration. It's like a small monthly amount, I think $10 per map, and of course, Streeto is accepting it. At the other station, I also became accepted in the GitHub sponsors program, so this is another way to help the project, so it's sponsoring GitHub, and that actually GitHub will match the sponsorship, so whatever you provide, GitHub will provide the same amount, so that's pretty cool on their side, and you get some small things like kickstabs and things like stairs and stuff. And generally, the best support will be users, so if you guys want to use it and want to try on your data, just try to use it and give feedback. I would like to close with this tweet by Smoldek. He essentially says that there is no question that there is a list anymore. Everyone is on it. The only question is, where is your position on the list? So do not feed the list of the big man further. Do not use centralized services. Thank you, that's all.
