 Okay everyone, we are about to start the next talk with Vick Sharma of Cake Technologies, which is the creator of Cake Wallet. Cake Wallet is the most used and the very first Monero iOS Wallet. So please give it a hand for him and enjoy his talk. Actually I've never seen the room clear out faster than uh when they announced my name. So uh everyone can hear me? Yeah, okay. So uh I'm Vick Sharma. I'm the uh founder of uh Cake Technologies, which is Justin said, is the maker of Cake Wallet. We were the first Monero Wallet for iOS, um first open source wallet for uh for Monero on iOS. Um just to give you a quick um background of me, I'm um I'm actually, you'll see the last line, I'm actually uh head of a steel company for the largest uh wire rod producer in the US, uh 1500 employees. So that's my real job. So um on Cake Wallet we've today we've got close to 18,000 unique installs that's unique per Apple ID. Um and the uh Apple App Store also shows active users per certain amount of time. So we have roughly a thousand active users uh weekly that are actually using the app. Um since its first launch we also put in uh three exchanges, those are third party exchanges, um which is Morph Token, um XMR2, and Change Now. And people always talk about what kind of volume they're uh they're doing through the wallet. Ask me in private and I'll let you know. We don't make that public. Um so I'll just start here. So this is a some uh screenshots of our app. You can see the send screen, receive screen, exchange screen, just standard wallet stuff. So we started building the app in middle of 2017, June, July, and we built it in a vacuum. We didn't consult with the community, we didn't talk to anybody. I think we went to the uh Monero Reddit maybe once and saw okay they're working on the community supporting some wallet and we said okay let's ignore it, let's just do our own thing. And we continued and we launched in January of 2018 and we were close source. But we didn't know we were close source. We didn't know we were what open source was, we didn't know much at all. So we learned very quickly from the community that uh if it's not open source then get out. So I'll just I'm going to jump around here on the slides if you don't mind just to show you some feedback we got from the community right here. These are actual screenshots from January 2018 reply from the community. No open source thanks but no thanks. So some people are very harsh you know let's see the code not going anywhere near this. So the community spoke loud and clear so we really had to quickly get our act together and just go back to this screen. So close source uh open source I didn't even know what it meant right I didn't know. I'll tell you what I thought it meant and uh feel free to laugh. I thought it meant if you're using some part of open source code that's already existing out there and you're using it then you're open source. Well that's not what it means it means you have to open your code you have to open your source and show all the cards yeah. So started looking and by the way this is our this presentation is on our journey of going from close source to open source. So we reached out to the community so you'll see there's my uh comment on Reddit from January 2018 any advice on making it open source would be appreciated yeah. So you guys know uh user rarar Diego from cypher market he was the uh first one to reach out to me and he said this is exact word he's like dude you gotta go open source. So we started doing research getting educated uh Diego was really helpful and it I'll tell you it's very confusing there's just so many different licenses there's so many groups maintaining licenses um so we just looked at a few and in the end we ended up going with the MIT um with the MIT license. Why did we go with that? Because it's very broad we thought okay it's uh if we're gonna go open source we're gonna put it all out there let let's make it broad let uh let people use it let people modify it let people um launch their own apps with it um but that was a big concern of ours yeah. So before I get to that I'll just quickly so what is what is open source software free and open source software um I'm not gonna read it to you but there's no universal agreed on definition but this is pretty much which most of the people agree on and why isn't it agreed upon because if you see the description there you'll see for any purpose modify the program as they want test freely distribute blah blah blah but different licenses have different limitations you know you some have you can't use it for commercial purpose or you can't use it for this purpose or you can't modify it or who knows bunch of bunch of different guidelines for different licenses but this is a very broad definition and I think most people agree that this is the broad definition you know so who maintains these licenses where do they come from so again there's there's many people there's many organizations but the two most uh that people follow and uh they maintain these licenses one is the open source initiative and the other is the free software foundation um and there's again there's just so many different licenses it's I'm not gonna go through each one but by the way doing the research on this I came across the last license uh doing research for this presentation I came across the last one I think we should have uh gone gone with that one it's do whatever the fuck you want with a public license it's actually a license you can use it so what was our biggest concern at the time when the community said go open source go open source our concern was exactly this that someone's gonna take we're new to the community we're newbies there's people smarter than us there's uh people more involved in Monero than we are that'll be listened to and respected more than we are than a new player and that was our concern that someone's gonna just copy it and somebody within the community somebody everybody knows and they're gonna build something uh better and faster than us and we're gonna be cut out so why is that and again I think it all comes back down to the community and the community supporting what you're trying to do and um willingness to go open source that's very much rewarded in the Monero community so what are the advantages of going open source now there's numerous advantages but I just wanna hit on three which which really affected us and which we appreciated if we went through this process was again the community the first one was the community so let's go with that one so if you go open source if you have an app out there and you're worried what's gonna happen same concerns we had you're gonna become part of that community there's gonna be a commuter that follows you there's gonna be community that supports you they're gonna give you ideas and they will criticize you brutally but uh it's it's very much needed and people are mean to us by the way when we came out um again so this was a community response and you know that that spoke highly and I mean comment after comment if you go to our original Reddit post comment after comment open source open source open source even for as we're trying to figure out every day I would get a message when are you going open source but the interesting thing was that showed me that okay there is a huge demand for this app there's a huge demand people want something like this but they just want something they can see they can trust um and verify yeah so another great advantage of going open source is longevity so even though my biggest fear was that we're gonna get cut out and somebody gonna copy us and by the way somebody has copied us they didn't do it for Monero but they did it for a Monero fork coin I don't remember their name right now um which is fine but longevity if something were to happen to Kate technologies today something happened to me somebody happened to our developers somebody in the community can pick it up and cake while it will continue they'll hopefully improve on it modify it to whatever the the community likes or customers like so what we thought was uh our biggest concern it can't turn out to be the biggest asset I feel that cake while it will continue yeah um and you even see um people would contribute and that happens I mean that happens a lot um a lot of people call us or a lot of people modify and do whatever and we incorporate those changes we get the community involved security I mean Monero being money oriented and being uh value oriented that's always a big concern I remember getting uh comments that how do we know you're not stealing our Monero how do you you probably have a code in there that once you hit 10 Monero then you take our Monero so by the way that number is 100 not 10 we're not cheap so but so far nothing so far no uh no losses and uh anybody's Monero uh in cake wallet it's working well but but people like that feel they want to know that the community has has vetted the app has looked at the code and again if you go back and look at look at Reddit comments many many other users have come back and said hey guys I've looked at the code everything's kosher everything's great this is uh this is fine and they're not stealing our stealing our Monero so I guess this is going much faster than I thought um conclusion is don't fear open source um the community will back you they will reward you um in terms of use in terms of technical support in terms of marketing support um and I'd like to leave everybody also with a little life lesson uh which we we went through while building cake wallet don't worry about it what other people are doing yeah when we started building cake wallet we went on Reddit by mistake and we saw there was somebody built in the community supporting some other wallet and at that time we could have said oh no there's uh they're already building another wallet let's not do it but we ignored it we thought okay let's not worry about it so it's a little life lesson if you want to do something if you want to build something go ahead and do it don't worry about other people are doing because you may be smarter you may be doing it better you may be doing it differently um so for me that was a huge life lesson during uh building cake wallet so sorry I rushed through it but uh that's the presentation yeah questions
