Chainlink Hackathon | Closing Ceremony

hello and welcome everybody to the fall chain link hackathon 2021 closing ceremony we are incredibly excited to be having this closing ceremony after such a long hackathon about a month right a little bit more than a month here it's been an absolute wild ride watching all the developers build mind-blowing incredibly creative powerful unique applications that are going to power the future right i've said it at the beginning in the opening ceremony but these hackathons are the stomping grounds of innovation it's at these hackathons it's at these cultivations of ideas and community members that we build the future of technology and of web 3. we have an amazing and absolutely amazing lineup for you today where we are going to be going over the winners of the challenge and i'm incredibly excited for this because these projects were fantastic so let's just jump right into the presentation because we have a lot of projects to go over let's do it so before we actually jump into all the projects and all the different amazing winners here let's just talk a little bit about what happened who came here who was here who was at this hackathon now we had over 7800 registrations nearly doubled from the last hackathon we had 989 insane projects amazing absolutely fantastic we had 92 people using chain link api 90 people using chain liver 64 people using chain link data feeds 46 people using chain link keepers we had an absolutely insane amount of projects using all these different chain tools to build these incredibly powerful hybrid smart contracts right and one of the things that's also fantastic is the vast majority of people here were new to blockchain i think it was about 50 of the people here are new to blockchain they're new to engineering and they came and they built something and they submitted something and a lot of them might have won which we'll find out in just a second so with that being said we absolutely amazing turn out here this is more than double what we saw at our hackathon in spring and just in six months more than double the size of the tackle the more than double the um projects came here um and just built amazing things so before we again before we jump into the project we have to have to have to give a major thank you a major shout out to all the fantastic sponsors who were a part of this uh there are so many wonderful participating technologies here if you see any of these definitely 100 be sure to give them a thank you and additionally not only the sponsors and participating technologies but a major thank you to all the hackers and all the community members and everyone who came to sacramento and made this a massive success of course this includes a lot of people at chain link labs uh who i've given a shout out to before i'll give a shout out at the end of this presentation as well thank you all so much for being here and being a part of this uh it's it's an absolute ride and we are so excited um that you're all here and you all decided to take part in this hackathon together so um with that being said let's just jump into it let's jump into the surprises so i i know i said in the uh in the calendar invite that this is gonna be about two hours i think we're gonna we're gonna make it a little bit shorter than that we're gonna get right through these so there were 550 000 in hackathon prizes here um an absolutely insane amount all right just uh picking somebody who can't get into this to the studio here that they we will let them in shortly we will let the winners in shortly um 550 000 hackathon prize winners and we are going to be announcing at this presentation all the major prize winners so everyone else will get notified of their winnings next week via email we um we didn't uh not all the prizes are finished judging um this is just all the major prizes it's the vast majority as we go along we'll tell you which ones we did and then which ones we uh we haven't yet so again the sponsor prizes are going to be handled by their respective team so if avalanche has a prize the ava labs team will be the one to give out the prize so uh and the chain link prizes the grand prize you know et cetera that will be handled by chain link labs so let's just jump into it so our first prizes on the list is going to be the chain link on the rise winner these are projects that were absolutely phenomenal there they came into this space they built something really cool and we wanted to recognize them for that so we have 45 of these projects don't worry we're not going to go through all the all of them 45 of these products 500 and link to each one of these projects um absolutely phenomenal job to everyone here everyone on this list that showed up made something really cool learned a ton and then additionally they're going to get some money right and that's a blast so i know there's a ton here but this is the list um of the 45 products that won this prize we will be emailing you we will be sending um some communications to give you uh the prize here of 500 each uh in link token so this is the list i'm not going to uh rattle off everyone's name here because there is a massive amount but if you're kind of curious you know feel free to pause the video and see if you're on this list additionally we will go back and we will email you so you will get communications from us saying that you won congrats to everybody on this list everybody on this list had a really fantastic project and they deserve recognition so huge congrats to everybody here additionally we have what we call top quality winners these are also projects that did fantastically well we thought they were like just below um or we thought that they weren't gonna win one of those major prizes but they were still absolutely phenomenal prizes they could have just as easily won um but unfortunately you can only choose one winner so these were the top quality winners so there were 20 of these prizes of a thousand dollars and a huge congrats uh to them as well these are the projects that we consider the top quality projects for the thousand dollar link prize we have block reg strong incentive home page doubt obey alchemist war drop shot fantasy campaign hourglass uh satellite broadband service chain uh we uh weigh gold steady dial daily stacker net dot zero builder rig struck finance easel studio swap ball b tsunami protocol and hack a dot link absolutely fantastic job to everybody on this list here uh a thousand dollars each and you learned a ton you networked a ton you met a ton of new people this is absolutely phenomenal huge congrats to everybody on this list and i'm really excited to see what these projects build in the future their journeys are just really just getting started here right this is really just the starting points so huge congrats there now we're going to go over the sponsor prizes this isn't all of the sponsor prizes this is going to be um some of the uh the majority of them some of them still haven't finished judging uh 300 projects is a lot to go through in about a week and a half because that's how long we gave them to judge so some of them are still judging we'll let you know at the end uh which ones are have not been uh judged yet so let's go ahead and so first off the woman led winners so originally there was just one uh prize of ten thousand dollars we actually ended up splitting them into two because they were just two absolutely phenomenal projects sigma and qrik nft uh really really cool projects congratulations to the two of them um uh mgd uh was the the dow behind this to help bring this to light so these projects absolutely knocked it out of the park huge congratulations to figma and qrik nft for five thousand dollars each um huge congrats moving right along uh and again i'm gonna be a little bit quick here because we have so many products to get through and there's a couple projects waiting to present uh the morales winners is uh regales regales i hope i'm saying that right huge congratulations that's a ten thousand dollar prize from morales and additionally there was a pooled prize something like thirty or forty thousand dollars for the rest of the protocols that used morales which is absolutely exciting that you all use morales and you all literally get to take part in a prize simply by using the technology right these pool prizes are so fantastic so huge congratulations there ufo gaming has three absolutely massive prizes space tumble wins first place of thirty thousand dollars in the ufo token second place is gonna go to plantation third place pika place pokedex of five thousand dollars and for those of you who are here um who are who are watching this right now you can also check all these out right in the project gallery of the chain link hackathon so for those of you who are like oh that sounds like a really cool project like what is that what does it do go to the the chain link dev post and you can see every single one of these projects in here every single one of them you can sort by prize you can sort by what they did you can search um like i said an absolute massive oh i got it wrong 288 sorry not 289 um but you can check out all these projects you can contact them you can ask them about their projects um they all did a phenomenal job really fantastic job to everybody in this project gallery here but in any case um yes these are the three winners for the ufo prize a huge huge congratulations here uh this is a this is a massive prize here so awesome uh moving on right along next is file coin the file coin winners so falcon had a couple of winners here as well d social net first place of fifteen thousand dollars in file coin huge congratulations there uh social for their social media prize um dapro i hope i'm i'm saying that right of eight thousand five hundred dollars in five coin nft slash web storage uh there were two of those nft bingo and eco shift both won um uh four thousand two hundred and fifty dollars which is fantastic and fall coin additionally gave out pooled prizes right so when people were like hey should i do a hackathon the answer is like yes yes go to a hackathon and just use one of the technologies uh because out there all these pool prizes exist where you they'll just reward you for just using the technology which is fantastic huge congrats to everyone on this list as well let's keep it going let's keep it going polygon polygon had a ton of prizes gaming depth chess link three thousand dollars dow tooling governor c three thousand dollars nft matic mike three thousand dollars chain-link vrf chain lin uh rand price feeds space tumble each one of these projects won three thousand dollars uh in polygon which is absolutely fantastic for building these really really cool projects and again if you haven't checked out these projects after this presentation after this closing ceremony go to devpost and check out some of these products because they are absolutely insane and who knows maybe this these are the next billion dollar protocols right 100 go check this out so huge congrats to everyone on this list here uh polygon additionally had some runner-up prizes here seven run art prizes of 500 each token rage space tombow uh b plantation fantasy campaign hobbits of polygon and punchable each one 500 from the polygon uh protocol fantastic awesome job awesome job everybody ample fourth hourglass fellow class seven thousand five hundred and apple and two thousand five hundred apple these protocols really understood the ample fourth uh technology which was really cool to see right so if you wanna see some protocols and some engineers that really understand what ample forth is and what it does definitely check out that project because they did a beautiful job here congratulations to both of those moving along solana the tsunami protocol won first place there uh which i believe was ten thousand dollars sorry i don't have the number on here um congratulations to the tsunami protocol next we have ceramic in three box this was a pool prize so anybody who used them wins congrats congratulations to anybody who used ceramic uh and who actually used three bucks in in their prizes or assuming in their projects uh you win a prize congrats harmony uh harmony had a couple different uh prizes here a couple different projects they had the pica for the gaming prize pika place pokedex uh won the prize there for their composability award nft lift and for the best harmony and chain link integration swap vol congratulations to the three of you there uh alchemy pool prize what so if i just used alchemy i win yes spot on yes he did alchemy also had a main winner um they have not finished going through the projects yet because again there were a lot of protocols that used alchemy uh makes sense uh because alchemy is a phenomenal tool so a main a winner will be announced soon but anybody who's alchemy in their projects you enterprise so huge congrats to everybody who who saw this who took advantage of of the generosity of the alchemy team right they gave two months of of free node use which was absolutely fantastic so thank you so much alchemy and huge congrats to everybody who used the alchemy tools here there were a couple that have not been judged yet the list is here uh avalanche echo enf near seven ventures i have three box on here even though that is incorrect apologies um sushi swap binance superfluid and nft port have not been judged yet uh additionally the educational winners of eat the blocks depp university and chainshot have also not been done yet uh we're still working on them we will email you we will connect with you if you want one of the boot camp seats which is incredibly exciting for all the new engineers who want more uh informational on how to actually move forward and how to you know learn more about this uh about this web 3 space so awesome job now let's get into the chain link winner shall we i mean let's get into the chain link winners it's a chain link hackathon right it's a chain-link hackathon let's do this so first we're going to talk about the 30 welcome nfts this is another one that's going to be to be determined so we had a the welcome track for this hackathon where we have these prizes like the boot camps that we just went over for new projects coming into the space so um we have not gone over the welcome nfts yet uh we will do that and we will email the winners there which is will be uh incredibly exciting for the new projects to get that kind of a push saying hey you know your new project and that's great you're welcome here you did a great job welcome to web3 and now let's get into our first let me switch screens here real quick let's get into our first major prize right so we had a number of major prizes in this hackathon here right and again you can check those out on the dev post what those major prizes are if you scroll down you can see them all there we have the grand prize thirty thousand dollars in link we have the chain link social impact prize of fifteen thousand dollars in link the nft and gaming prize fifteen thousand dollars in link the d5 prize fifteen thousand dollars in link the dow prize fifteen thousand dollar length chain link services three of them one was fifteen thousand dollars one was seven thousand dollars and one was three thousand dollars for anybody who builds a really cool chain link service and those are going to be the major prizes that we're going to go over now so this is these are these are the big ones right uh really excited for this really excited to announce these and again uh everyone who who didn't win a prize here um i'm just i'm still so proud of you all right for submitting for coming to the hackalon and for learning there are a couple people i talk to and they literally get yeah i don't even care about the prize i've learned so much from this hackathon i'm ready to go on and do the next thing so huge congrats to everybody who said who said i'm gonna take this hackathon and i'm gonna be committed this is where i'm gonna start my journey this is how it starts this is where it is here's congrats to everybody who's been a part of this uh and even if you didn't win an award here that's okay huge congratulations huge round of applause you should give yourself a huge pat on the back um because you are welcome here you are a part of a fantastic community and we are going to do fantastic things 2022 is going to be insane it's going to be insane and you're along for the journey so with that being said let's jump in to these major project winners are you ready cause i'm ready oh i'm ready let me switch back to stream mode here all right first is the social impact winner this is the project that built something to help humanity it built something to have social impact help the world they built something that using blockchain using smart contract is going to transform the world to be a better place and that winner is so lay with fifteen thousand dollars in link to soleil so i believe soleil is here uh i believe soleil is here i got i got matt here matt is your uh is your part um is your is your buddy here too um i'm not sure he's called sam humpby if he's there i don't know how i see who horse is here he might not be um if he's in the comments section please uh go ahead and and message something in the comment section i i only realize now that 12 people can be backstage at a time um so if you're here post a message otherwise matt we will uh we will turn it over to you uh cause huge congrats and we're gonna have all these winners do a quick demo of of what their product is a quick five-minute demo so that we can get through all these uh fantastic projects right away matt uh you're also and then we'll do a quick quick quick q a about the project uh because again these are the products that that go off in the launch and they do the next next big thing so um matt without further ado we'll turn it over to you give a little little demo of your project here awesome thanks so much and i'm okay to share my screen how do i do it yes there's a share screen button at the bottom here we are i've got it i think oh i have to add it to the stream uh i got it all right right here perfect all right costume queen i'll just quickly run through a little presentation and say yesterday's um basically a project that aims to help fight climate change by building two services for everybody to use um little emojis here so first product first service sorry is to provide a way for um people to incentivize the entire solar industry with one transaction and the second is to provide a um a free public feed of solar energy data um aggregated from a range of providers so here's roughly how it works so um users can pay die into our pool manager smart contract so for example that would look like this from the user's perspective the die is then distributed to solar panel owners that have registered with the system um proportionately depending on how much energy they've generated that day i see also when the users yeah they schedule how long they'd like that die to be paid out over as well um as a reward for um incentivizing solar panel owners the users are then rewarded with soleil tokens like native token um uses of that token undetermined as of yet but because it kind of represents that the user's done a good thing it's kind of like a pseudo carbon credit um hoping that other people will be able to kind of build an economy around this token and indirectly fight climate change by incentivizing people to use the solid platform and so because the dye rewards act as an incentive for um solar panels to scale up or get set up in the first place um and they also incentivize them to provide their data to us as well so we can build up a large public data feed of um solar energy generation data across loads of users across loads of different providers and we used ceramic to store that on ceramic kind of built on top of ipfs but let's just use let's just create kind of mutable data streams on top of it and it's also a lot a lot cheaper than storing it on chain um see we made three um data feeds so we've got a data feed for the energy generation per site that's registered um a data feed for the die earnings per site and a data feed for the solay rewards per user um yeah to make the payments gas efficient we look to a cumulative knuckle drop solution so instead of sending transactions to all of the users and all of the sites um we've got a chain node that will analyze the data feeds and calculate the merkle root of that submit the nuclear route on chain and then users are able to make claims through the website to um claim their tokens when they're available to them and they can do partial claims on that as well um yeah the government grants already already exist for solar panel owners in a lot of countries but not in every country and um but this is potentially much more efficient um it's completely transparent and it's easy to analyze the growth of the network and the solar industry um you don't have to be a government to participate in this but you could be you could be uh like a company uh individual anything um and the data feed that we generate as part of this could be used in loads of other projects as well so next steps would be to work on decentralizing this as a few centralized steps at the moment so we could decentralize that at the data source level so as well as comparing api monitoring monitoring api data with um so we can compare that with satellite imaging data and weather data to kind of verify that it's true um we can also have multiple chain link nodes collaborating on maintaining the data feeds and we can add governance into the system as well so some examples of things um we could add to improve the platform as well is that you could have users being able to direct their funds to sites in a certain location so we might want to fund sites in developing nations for example or incentivize new sites um or um pay sites more if they're giving more back to the grid rather than just using the energy themselves stuff like that so to grow the network we do obviously obviously support more monitoring apis at the moment we're only supporting one and um look to kind of kick start the network with some with incentivizing initial users as well um but yeah beyond the seller industry this kind of pattern could be used um for a different range of things anything where you can kind of you have a lot of people are contributing to a common goal and their progress towards this goal can be measured um empirically you can um reward them all in the same kind of way and so yeah just some other examples where this could work is other um sustainable energy sources and you could do one for open source software if because you can measure um the number of github stars and forks you can kind of get a judge of how useful a project is to people um rewilding reforestation using satellite data you can if you've got a landowner they might register to system and say i'm gonna rewild my farmland or something and [Music] yeah funding aid in developing nations so you could have um people somebody say i'm gonna um yeah go and build a well and you can verify that with satellite data and like you can measure the progress basically towards helping a big goal yeah whether that's energy as well or immunization rates in that country and that's it um i can show a quick bit of the web app but yeah just a big thank you to chain link and all the sponsors like some of the sponsor prizes are absolutely huge it's insane matter in the interest of time i'm uh oh it's it's so cool your front end is so cool though uh in the interest of time i i i do gotta move us along but i do i do wanna do one question matt um especially for you um and your teammates so you're uh you're a hackathon veteran right this isn't your first rodeo you've done a couple of these what have you learned what's the what's the main differentiator between this hackathon and the last hackathon and and i think you won what uh you won a prize two hackathons ago was that it you won the main prize two actions ago yeah so it was in the first hackathon which was really my first time doing any kind of blockchain stuff at all that was only a year ago um but i was mostly doing the front end for that one i didn't really understand well i didn't know any solidity or anything back then and since well over the past year i've kind of gradually learned it in my own time um the last hackathon did some solidity done more in this one and yeah just learning more and more and learned about ceramic this one which was really interesting i didn't know anything about them before always yeah awesome i absolutely love that man yeah so a year ago didn't know anything about solidity was new to blockchain uh and now he's you know you and your team you're winning prizes you're you're building these really cool projects like and so lightweight it's this fantastic tool that can help the world right using blockchain um absolutely phenomenal job matt to you and you and your team um your teammate is not here um at the moment unfortunately what was their name again sam humby sam humvee so huge shout out to sam humbey for those of you in the comments saying hey um where can i see a demo of this 100 go to the dev post um the chain link hackathon dev post for fall 2021 a look up soleil they have a link to uh their working demo uh and it's really really cool so definitely be sure to check it out so uh thank you so much matt and the solely team and huge congratulations again all right cool uh and and matt uh if you could drop off the studio uh just so that other people could join uh thank you very much appreciate it so awesome job and that's just our first one right so a couple people in the comments i see going oh my goodness look at that look at that ui look at that use case really fantastic you know join web3 join blockchain right in a year he's learned something you know building these awesome tools all these awesome protocols and something i forgot to do was i forgot to talk a little bit more about why these winners are such a big deal right so just quickly looking back at the stream you know our last hackathon winner uh bridge raised 5.5 million dollars right so these protocols yeah they're cool you know they're hackathons they also go on to build fantastic things right um vulcan exchange from the hackathon back in spring brought on mark cuban as a um as an investor right which is absolutely massive so and a lot of products actually do start from hackathons for example one inch dot exchange you might have heard of them they also started off as a as a hackathon as a hackathon project um and additionally all of these projects that are participating here are going to be eligible for assuming all these products that win here are going to be eligible for the vc pitch day where they get to pitch their projects to venture capitalists to get some funding to take their ideas from idea to full-blown protocol so who knows in a year maybe these are gonna be the protocols that are dominating the web 3 that are dominating the block space and i mean we are just so excited for all these projects in general but in any case let's move right along shall we there are so many phenomenal products that we have to talk to additionally be sure to uh to reach out and say hi to these teams and ask them questions um just a really fantastic really cool product right soleil is really really cool helping the environment you know using blockchain so but moving right along as i've said like 15 times now we're going to go into the services category now so what are chain-link services so chain-link services are anything that helps the chain-link ecosystem grow better grow stronger and do something right so these are the projects that enable developers to build more of these hybrid smart contracts in an easier way and that's what these channeling services are and that's exactly what the winners that you're about to see have exemplified so let's jump right into the three winners so we have kotol adapter.js and chainlink iris so total first place with a 15 000 prize adapter js with a 7000 prize and chain link iris with a 3 000 prize in link i believe we have some of them here i would i would love to start with chain link iris um chain link iris are you in the chat here uh let me let me find you here uh ethan yes ethan hi how are you good how are you doing welcome welcome ethan all right so five minutes on the clock my friend okay tell us about chain link iris yeah um let me see if i can share my screen yes yeah there's a little share screen button at the bottom all right there we go can you see my slides you're in my friend awesome all right well i just want to say thank you uh first of all to all the sponsors and the chain link um super organized this hackathon super impressive and a lot of great resources so thank you um i'll guess i'll get right into it my project is called chain link iris my name's ethan bond um so basically the the problem that i set out to solve um was when i was you know researching and brainstorming i found you know the whole purpose of chain link is you know share data between oracle's and everything it seemed you know if you don't have a specific you know knowledge base to be able to interact with existing apis or know how to make custom solutions for certain iot devices like seen on this slide or certain sensors for a non-technical person to be able to get data you know real analog data that's in the world of atoms rather than the world of bits onto the blockchain um you know there's not a whole lot of solutions that i found for that that are really broad and could fit a lot of use cases and so i thought a lot about that and how could you make it so that you know there's already an adapter in place and and what could people use and the solution that i came up with i called chain link iris and basically to go through an example i think would be the best it uses computer vision um so the idea the example here would be you know say you have a local sporting event so in this slide it's a hockey game um and you want to take data about that event and get it onto the blockchain for you know whatever your use case whether it's betting or just keeping a record of some kind um and you know if it's a local hockey game you're not going to have espn or fox sports recording those scores or or the data about that so the thought is that someone could register the event with chain link iris and and with it they register a data policy so there would be a big set of data policies that say hey use this specific computer vision algorithm to to extract this kind of data this is what we want from the frames that are sent and then anyone with a camera or like a smartphone would be able to you know through the the chain link iris endpoint stream video stream the frames of the event to chain link iris which would then uh implement that data policy and extract clean json like seen here so that you know it's very simple this example score home in a way um [Music] so there's that i was going to do a demo and i'll give it a shot here but i my computer is running really slow um so i already have this event registered here and and the data policy i call it um that i have for it is is just to read text um so you can see me there you know it's very rudimentary i just have this piece of paper that says chain link on it so let that register on there and it's been recorded and now if i go i i don't have the local node running to call this from a contract or anything but i'll just show you at the the end point um the api if it loads um you know it's very basic get request that just has the data um yeah see that's running slow um so while that's loading i guess one of the other cool features i when thinking about this is you know if it were you know democratized you could have all sorts of people anyone who they wants to um could upload you know stream video and it would be kind of trustless there would be no single person streaming um the video here we go it loaded so we have chain link we have the date um and i'll go over this so one confirmation here means that only only one person only i right now i'm the one uploading this this specific state of this event uh right now one person has confirmed it and this time off is something else i wanted to go over was thinking about you know how could we make it so it's really hard to you know take over and hack this and have people send data about you know other events and the person who's putting on the event could use something like this i called it you know time off and basically it's just a bunch of boxes that have different colors you know that it's reprimand represents binary and it's it's a you know a mod of the time stamp from when the um when the event has started and obviously this isn't random it's just incrementing by one but ideally this would be if this is in the frame it would be another step to make it harder to fake what's going on in the frames um and you could be able to show um you know have more people submit data and have it all confirmed and synced up by time um so that was really the idea there um and that's about all i've got so i'm gonna stop sharing there ethan fantastic yeah when i saw this i was absolutely blown away like the demo that you did uh was really telling right in the in the video for everybody who wants to go check it out go to the uh the chain link dev post again he does a video where he shows a real time he holds up little flash cards they have i think was numbers or something you know it interacts with chain linked and this is the power that we really have right it's truth not trust that's what we're looking for with blockchain so so ethan uh with something like this which is so cool like i feel like this is just it's like cool like this is cool what is um an application that you're most excited that would use chain link iris i think um the example i gave in there would be sports related um and not just for betting or whatever but for you know for data uh you know analysis um and and anything sports having like a decentralized sports api i guess you could have like a casino with that or something it just sounds like fun to have that and have no you know single authority that's um you know determining where that that information comes from so absolutely well phenomenal job ethan congratulations on being a chain like hackathon winner here thanks so much yeah all right great uh we're moving on right oh i'm seeing some some humorous uh uh comments here but massive absolutely massive right that feels kind of this ultimate vision of these smart contracts really doing anything taking in this iot data uh and being able to do uh really anything right so this is really phenomenal giving developers the ability to build more applications so uh speaking of which uh that leads us to our next winner our second place services winner adapter js adapter js are you here uh i believe you are i'm looking uh i'm looking i'm looking well maybe you're not here adapter.js might not be here which is okay adapter.js if you are here just post in that private chat um if you're not here and you come on later we'll we'll have you present a little bit later um so it looks like adapter.js is not here uh no worries i'll do a quick uh explainer of what adapter.js was so for those of you who know chain link extern chain link nodes are 100 customizable you can make them do whatever you want as we just saw right we saw ethan build chain link iris with customized as chain link nodes to be able to take in iot data right to build these decentralized smart contracts that use you know data that it sees in the real world now building these external adapters can sometimes be a little bit tricky they can be a little bit hard you can be a phenomenal smart contract engineer and maybe need an external adapter to do something and maybe you don't know how to build that external adapter so adapter js is a no code solution to building external adapters it's a no code solution to customizing your chain node to be able to do literally anything so adapter.js really blew us away it was a really fantastic uh project to give developers this this tool to make it easier for them to customize their chain like nodes without even having to code right and some people who might be a little bit technical might be thinking oh well they're engineers like why would the coders not code engineers are just like the rest of us we want the easy solution we want the easy if there's an easy button i'm going to hit it right so this is an easy button for spinning up these external adapters so awesome job to adapter js again definitely go check them out on the uh dev post for this hackathon and for first place we have koto kolto i believe you are here i see your your uh your screen share uh and i see you hello welcome hi hi dr how are you doing thank you for the amazing event thank you so much for being here i'm really excited to hear about kotol yeah i will start presenting now so hi everyone kotal is uh i'm suffering founder of koton kotel is an open source company with a vision of simplifying blockchain devops so using total you can deploy nodes you can expose ebay in the points and you cannot stick across multiple protocols whose little or not blockchain develops experience currently we are supporting a serial one the cerium ii ibfs file coin and the volcano protocols and during the hackathon within a few weeks i and my team made ahmad salah we have added support for chair link to kotov we love open source quarter source code is published on github so you can use our dashboard sdk dbi and you can read our source code you can contribute forward and you can support your protocol you can even deploy it in your own infrastructure google is working on google cloud platform microsoft azure aws digital ocean alibaba cloud or any environment where kubernetes is available so the core component of cotton is blockchain coordinates operator and we are building abstractions around it like kvi is the key dashboard and others here here is an example of depending on centralized closed close the source infrastructure and service like infuria so alfira goes down for more than eight hours back in the end of 2020 and the big exchanges like finance stopped extreme transaction processing because they are debating on this provider the same happens in israel initial user wouldn't be able to access venezuela to swap tokens because you are depending on the centralized cloud source cloud flare ib phase gateway you can think of quota as an open source alternative to centralized api gateway and node and service companies you can think of quota as like gitlab to github it's open source you can download it and you can download in your own infrastructure to manage your notes and manage the whole livestock lifecycle if you of your blockage in hopes after the hackathon we will continue hacking and we'll continue developing our product we will support more protocols like polygon graph binance chain solana stacks and others and you'll continue building unmanaged hosted service of koto thank you patrick and i'm ready for answering any question awesome yeah this this was another project that i i watched the video and it was it was literally just like click click okay the chain link node spun up and i was like i need this i want this absolutely fantastic alternative is reading tons of documentation and it's tricky and hard it can be right it can be a little bit tricky and just having like a an easy button again like i just said for developers is fantastic um so so uh let me ask you a quick question here what was the inspiration behind uh doing kind of this this uh note as a service here what was the inspiration what got you into this yes the respiration is that in every ecosystem there is a closed source node service and api gateway that is uh consuming the majority of depths of traffic like in fuel efficiency for example in eastern ecosystem more than 50 more than 90 percent of traffic is flowing through and further and when infuria goes down all dapps goes down the same was cloud clear rbfs and with services like pinata and others so we are providing an open source alternative to the solutions awesome absolutely phenomenal here so any developer for your next project maybe take a look at codal right it may give you that edge so thank you so much for being here and huge congratulations for being the first place winner of the services award thank you thank you bye all right great so oh sorry um so uh we have adapter.js here thank you so much everybody in the comments for uh for mentioning that again apologies there's a there's a cap to the number of people who could be backstage i wasn't aware of this previously uh but morgan you're with us hello hello welcome to the stream thank you so much yeah a little difficulty there but we are ready to go awesome yeah so i'll uh better uh explainer of adapter js than i did yeah yeah so uh what adapter js is is it's an external adapter um which makes it much easier to add customization to your chain link request so right now uh you'd have to build your own external adapter if you wanted to have custom functionality to your chain link request and so why did i make adapter js because smart contract development is honestly hard enough already um and so if we can limit uh whatever difficulties are there while developing an external adapter i'm all for it um and so basically for other hackathon participants you may have had difficulty setting up an external adapter yourself uh either like getting the code to run or finding a node operator to host your adapter for you and it's also a struggle for node operators because every time someone wants to add new functionality to a chain link request they need to create a new bridge and a new job and this is the problem that adapter js is trying to solve so instead of you needing to create your own external adapter to make a customized chain link request you can just send a custom request right to adapter.js so here's just an example of what a request would look like so as you can see it's just got some filler data in here but basically whatever code you send as a string to the external adapter will get executed and the return value of that code is what is going to be returned on chain so an additional thing that external adapters do is they let you access authenticated apis think like twitter for example you need an authentication key to be able to get data from twitter and adapter.js actually also allows you to do that while maintaining privacy of your authentication keys and this is accomplished by essentially uploading your keys to the adapter.js database and then when you make a request on chain you can reference those uploaded keys and and make the request without actually exposing those api keys in a public on-chain request so i've kind of got a demonstration of how that would be accomplished here so um in this example we're actually going to be uh making a call to twitter and just checking a boolean value did elon musk's latest tweet mention bitcoin um so one of the cool things that i developed with this is is the simulator so this is the the kind of no code part that patrick was talking about so instead of you needing to write solidity code for example you do need to know javascript so it's not completely no code but javascript's fairly easy to learn and that's really all you need to know is just a few a few lines of javascript so what you would do here is you go to adapter.js.link and then you get this really easy to use menu where you put in everything that that you want so first you put the url that you're trying to hit um you've got your authentication token thankfully this is cut off so you are not seeing my whole token there um and then you can actually go ahead and upload this to the external adapter so this authentication header is not included in your on-chain request and then you actually put the address of the smart contract which is allowed to use this authentication header so not just anyone can use your private tokens in a request and then just a reference id to reference that and then we can set a test request first just to make sure it's working so you don't have to test it on chain as you can see uh false elon's latest tweet did not mention bitcoin and then finally here we can click the generate code button and what this will do this will actually generate the solidity code it's got just some instructions here for a little bit of setup but really you can just copy and paste this whole thing right into your smart contract deploy it and uh and you're good to go so you can see an example that right here this is the the string that's going to be sent to the external adapter in the chain link request and it's got your custom code right there so we'll go ahead and check this out so the initial value we set to true and then after we actually get the response from the chain link node it will set to false there we go so then they've got one other feature that i do want to go over with this and uh in addition to being able to access [Music] any authenticated apis if you have a really large bit of javascript code say like 50 100 lines maybe a thousand lines you can actually upload that javascript file to ipfs instead of sending all your code as a string in an on-chain request then you'll just send the content id of that javascript file where the external adapter will now download that file and execute it to process the data that was fetched during the http request i do have a quick example of that so again make it as easy as possible you don't have to know how to even write solidity so you come into this tool we got here paste in the url in this case we're going to go to an altcoin news page and just return back um the most mentioned top 50 alt coin on that page so uses web3.storage to upload the javascript file i've already got it all loaded we'll send request i had already sent it before so luna looks like it's most mentioned it was mentioned four times and then finally we generate the code so this code can then be pasted into the smart contract i've got an example of it here and then we'll run it and it should let us know that same value on chain so it should say an initial value here in a second you want to zoom in just a hair sure sure um yeah well you can see it's it's luna there uh not too interesting so we'll uh keep it moving here so as for future plans for this project so the future goal is to actually deploy this external adapter for nodes for ethereum polygon binance smart chain and avalanche and also any any other chains where users think they'll might actually use it anything that supports chain link i also want to add support for long strings currently it only supports the basic ethereum types you know bytes 32 inc bool et cetera i guess those are all of them and then also support multi-variable responses which is something that chain link has fairly recently added as an ability then also i want to add the ability for users to import kind of more common node.js modules so instead of having to pack everything into a single javascript file and upload it you can just import things for example axios if you want to make multiple http requests and maybe combine all that data and do a single post of all that data on chain that that's going to be possible very soon um and then also just continuing to add functionality like i mentioned the modules and then expand documentation as well so i also do i have an ask i would love people to join the adapter js.link discord so just go to adapter.js.link click the contact button and you'll be able to join our discord i'm currently seeking some feedback on what blockchains people would like deployed to and just kind of what people are looking for for new features awesome well morgan this is fantastic i'm so excited that you you did get a chance to present apologies for the uh uh little technical difficulty there uh i there are so many developers in the chat and this is one of the things i love about this is you can tell there are developers watching this right because you had so many people being like i need that i want this for for all these services right for this one um in particular too so i i do have a quick question so what's your background right how did you how did you know and how did you learn to use all these tools together what's your background what are your expertise in uh actually robotics is uh has been my main focus but i kind of fell in love with blockchain uh shortly after i got my degree so graduated in december uh with robotics and then kind of realized like wait blockchain's really cool and i can much more easily work from home if i'm doing blockchain stuff so got super passionate about it just started researching and uh and one of the things i really am interested in is the oracle problem i think it's the most interesting part of smart contracts and and i really want people to be able to access just any data on the internet very easily uh and and that was kind of something i've always been passionate about and once i started actually i kind of started off going a little bit of a different direction i started the hackathon i didn't 100 know i wanted to do this um but as i started making an external adapter i realized like i mean it's not super hard but it is a little bit more technical and if i could just build something to make that easier well that would improve the ecosystem and uh just make blockchain um that accesses data from the real world much easier for developers to actually make a reality absolutely i love the mission love the philosophy i love the mentality i feel like the three of you should all just get together uh and just build the sky's the limit when i saw the chain link iris project especially like because that was the first one i saw yeah like i was like i really i really want to get involved with that i actually i'm hoping we can connect because uh i think that you can make a larger vision of making these customized chain link requests much more accessible for people and super powerful ethan and morgan uh going to do great things in the future awesome well fantastic job thank you so much for being here thanks so much for presenting and showing us that huge congratulations thanks all right great so that is the services track oh amazing projects here uh we have a couple more right what do we have left what do we have left here we have uh gaming d5 dow and grand and we are gonna go in that order we're gonna go right to the nft in gaming this is another 15 dollar prize in link token the nft and gaming winner is space tombow huge congratulations to space tomball hopefully i'm saying the name of your protocol right i'm going to i'm going to pull all of you up on now oh i have one one space tombow uh where's the rest of the space tombow that's that's the share screen we have two oh how's it going good it's actually my screen that's shared oh it's uh you're you're you're like yeah the rest of the team was supposed to be there but uh they couldn't make it so they had a bit of a presentation made um but uh i didn't pick it up so i'm gonna improvise a little bit on on this so basically for uh for a space tombo um the idea was to you know uh when you when you want to donate some money to a charitable organization um like most of the time the process to do it is very formal like you know you donate the money through you know paypal or some kind of regular banking system and then you just go through and and great you you're participating into the uh the event but uh you don't feel like so rewarded as much and uh and so we were like okay how can we use blockchain to secure a way to get into uh people into lotteries that would help uh like a great social project but at the same time how can we bring more people well let's implement gamification and that's the whole idea behind space tombow so basically what you um what you do you create a lottery for a specified charitable organization which has a an ethereum address and then you you push the lottery events and all the parameters of the lottery on chain and then everyone can participate to it and once you participate to the lottery you get a ticket back and that ticket is an nft and what's uh the most interesting part is that this nft is actually dynamic what does that mean that means that the lottery has many many events and so all the like all the the money raised uh through buying those tickets are handed to one goal one specific poll that's called the hearth pool and so every funds in the herd will will go into the charitable organization address at the end of the lottery and uh there are multiple periods that i will just come here so it's kind of a technical diagram but it's a good way to understand hey here um i'm not sure if there's a setting you can adjust your mic is is given some serious feedback um okay let me see is it a bit better uh no um sorry about that no worries uh yeah we'll we'll just keep going let's get down i'm not sure i can improve that [Music] okay so uh sorry everyone for the quality of the audio today um so basically you you just create the lottery and all the parameters of the lottery the parameters of the events are sent on chain and so each event will basically pick some nfts down the line so let's say you have a 100 person participating into the into the lottery uh at each event there is a 50 halving so uh let's say event one you only have 50 people remaining and actually we modify the nft by uh by modifying the image of the of the lft and so we can do that and it's randomly picked using uh chaining vrf which is awesome so each event just triggers uh a chaining chaining vrf command that with the callback calls the event so once the lottery is created we have to fund the lottery with links in order for for it to just be able to start and once it's funded with enough links the participation period starts so everyone can get in it's very easy for anyone just to buy a ticket then the participation period just ends at some uh some time stamp defined uh at the lottery creation and then we have the preparation period so during this period you you can do a bunch of marketing about the lottery just telling everybody about the lottery and uh getting some hype around the lottery and you can modify your nft and they will uh enter into i will just show use case real quick after that and then the preparation period ends and then you get all the events and for now anyone can trigger them but we are planning on implementing uh chain link keepers for uh to to just uh uh trigger those events and i forgot to mention but the the price of the tickets are set in a fixed price in usd and this is made possible through uh chaining uh price feed so uh really really fast um i'll show you a use case here uh it's so that's the the name comes from there it's space tumble so it's a lottery that uh that happens in space basically you get your ticket um as an nft and so you can mint it uh let's say here i can choose and pick my my ticket i will i will pick my my little space spaceship here minted then i can confirm and then i have right now my lottery ticket and then during the preparation period i will be able to add some shields basically bonuses to this spaceship and then at every event the spaceship will evolve so let's say there is a storyline um all the spaceships just take off from earth at event one and they reach the atmosphere and so a good portion of those uh spaceships are just destroyed and so at the end of all the events you only have uh three winners um and again these three winners this is programmable at large recreation everything is set on chain unchained at the beginning and so uh and the three remaining nfts are the one who keep their image uh actually clean uh all the other ones just have a wreckage of spaceship remaining so that's pretty cool and uh the last event triggers uh the the release of the funds from the earth pole to the organization so um um and uh yeah really quickly that's uh a very important point all the funds raised during the preparation period so which is here goes to another poll that's called the moon pool and all the moonpool um funds will be released so there is a percentage for the charitable organization a percentage for the winners so actually getting in i'm gonna uh i'm going to do a lot of that to speed up a little bit just because uh okay well uh basically just a win-win situation uh in which you can you enter the lottery but you also have a chance to get some uh money back and uh and it's fun that's the same at the same time awesome yeah this project is so cool right uh and the thing is i think you won a couple other awards as well um just just an absolutely phenomenal look at this at this hackathon yeah really cool project art is fantastic the code was was really clean um but yeah what what's next what are you looking to do now uh well for so the next thing is to implement the keepers just uh continue to develop the project we have uh um an idea of creating a dao that will enable like people to get involved and actually help choosing what is the next charitable organizations we want to pick for the future of our space chips um so this is this is what's up to the future and uh i invite everyone everyone to just go on the website and look at the white paper uh there's gonna be a v2 uh version that's going to be available soon so yeah and i just want to give a huge shout out to the team uh so sucks and juicy they made an awesome work so props to them awesome well thank you so much huge congrats to you and your entire team uh really fantastic project all right cool well moving right along here um just a really cool project again if you want to go check it out um go on to that um to the chain link dev post there and play the game right it's fun like it's the graphics are really cool um definitely be sure to check it out huge congratulations there so where are we at now what are we doing now oh defy defy do people in the chat know what defy is do we know what d5 is i think we do d5 or decentralized finance this is the project that built a d5 integration with chain link as a lot of you know chain link is the backbone for a i want to say the majority of d5 protocols or or a large quantity of d5 protocols i think it's it's helping secure some like 60 80 billion total value locked right now um something like that so these are the projects that took that and said we're going to go further we're going to integrate chain link and d5 as well and the deep and these this project is going to win fifteen thousand dollars in link as well so the d5 project winners are actually two trade board and krypton we actually had a hard time uh picking just one so we ended up doing two which is going to be uh trade board and krypton huge congrats to both teams uh both of you are going to win 15 000 so huge congrats first we're going to have a trade board go a trade board uh which one is trade board uh looking in my chat here let me let me switch back to the stream it's tr uh tr red board is mike uh okay we have mike mike is your teammate here too hi patrick can you hear me i can hear you loud and clear we can all hear you okay no my teammate is just listening to us so thanks for the introduction and choosing us i can't express how happy and honored i am i know it's a cliche but i want to thank my teammate jiri and everyone who helped us during this journey so without further ado uh let's as and get this started uh you are probably heard of index funds uh basically index funds are a basket of stocks like snp and in blockchain world it's a basket of cryptocurrencies which everyone can invest into but there are some problems with current index funds they need some kind of management because because index funds should always keep a balance between a volume of assets let's say we want to always have a ratio of one to five between ethereum and chain link and keeping this ratio while uh allowing everyone uh to invest and redeem with their favorite asset is a challenge okay i'm saying that you are showing our project i'm gonna show the slides don't worry okay give me a second okay uh so uh the challenge is uh keeping the portfolio balanced while making it easy for the investors to enter and exit uh and this is a trade off you cannot have both uh at the maximum so uh we we made uh some kind of index fund with a little bit flexibility this flexibility uh allows us to allows investors to enter and exit with lowest possible fees even though they are investing with only one asset uh if they want to invest balance there there would be no fee for them so we have a example here we wanted to make a motion graphic but it was too hard for us so we made a couple of slides and i'm gonna go through them fast so you can pretend that it's a motion graphic so we have a in the initialized index fund uh and you as you see we have talking b and c and they are balanced and let and someone anyone can invest in balanced form and without any fee and he gets his shares as you can see or he can redeem his tokens and get the shares back and it's a real estate everyone is happy now let's say uh someone comes and he only has a coin b uh he adds the coin b to the mutual fund and now uh it's unbalanced he gets the shares but he also has to pay a small fee and this fee goes to a price pool and this price pool will incentivize anyone uh who wants to take opportunity uh to get this prize pool uh and uh by doing that he will make uh the mutual fund balanced again we'll see how it happens now let's uh say uh we have an unbalanced um index fund and someone comes and redeems the tokens b right and he gets the reward now we or someone can come and add some c to the co to the index fund and uh it's gonna get to the balanced form again now uh we we have some definition uh it's a slip page and it's that's the that's the flexibility i've talked about uh we set a max we can set a maximum uh a slippage on an index fund and the index funds portfolio would not go further than this slippage okay let me show the website it's trade board that i owe i encourage you to go and check it and give us feedback i don't know what why this image is gone okay we we have a index fund here i'm gonna show how it happens in action as you can see the index funnel started with some money and someone invested unbalanced and he get he had to pay some fee 67 cents and someone else came and in redeemed some coins and because he made uh the index fund a little bit a little bit more balanced he gets some incentives as you can see here we have some bigger players who invested and invested and make the make its first unbalance and then again balanced so here here it was the idea and we implemented an mvp and we are we wanted to make it even cross chain uh using chain link and that's it do you have any questions awesome thank you so much yeah i mean i feel like i i'm saying it over and over again um but all these products are are so cool like this is one of these these products where i like i saw this and i was like oh i want to use this like asap um so i guess that's going to be my next question what are your plans on rolling on moving forward uh okay as i said one of the plans is to make it cross chain imagine you have a index one from 10 different chains and you only have to invest with one of chains and you all instantly access to chain to assets from 10 different chains and the other one is to apply this idea uh also to mutual funds as you can see we are planning uh to apply the same idea to mutual funds so uh mutual fund the different uh the differentiate between a mutual fund and index fund is that the mutual fund has a active uh manager who will manage the fund and we also can apply this and reduce the costs of mutual funds uh that's it love it awesome fantastic well thank you huge congratulations to you and your teammate who is who's listening who's not sharing a really fantastic job and really excited to see the future of this project thank you all right great and with that we're going to move on to the other d5 winner which is going to be krypton who is also here um i think it's uh michael you're here yes michael hey patrick nice to meet you yeah hello nice to meet you as well and i believe you're sharing your screen oh yeah so let me just move over to the slides and i'm going to show you a little bit about it and we can get into some questions later on i'm going to stop the camera if that's okay and then just talk about it and so first of all i want to say that thank you so much for putting together this hackathon to everyone the judges the sponsors the organizers these hackathons are really an amazing opportunity for people to learn that's what i did when i participate in the hackathon i think six months ago or something in the spring i didn't submit anything you know basically i spend all my time learning about chain link technology learning about blockchains and so on and so forth i'm actually quite recently into blockchains took my first validity course in january and realized um there's just enough possibilities endless opportunities you you can build and invent anything you want and nobody can stop you so blockchains are really a way to solve some of the uh society's biggest problems and none of the centralized incumbents can do anything to prevent you from doing what you want to do so what i think is that um looking back the landscape the technological landscape in blockchains just changed significantly in the last couple of years so if you go back to things like uni swap you know um synthetics other you know the first wave d5 protocols which essentially came out i think of you know 2017 2018 um they didn't have the technology we have today and so krypton would not be possible if we did not have high performance blockchains like avalanche if we did not have chain links technology so chain link is quite integral to what we're doing with krypton and so krypton is trying to solve an age-old problem which is that um in all of trading there is uh losses to toxic traders so in d5 you know this is front running sandwich attacks um in classic markets there's front running too um but there's typically something called adverse selection you know that somewhat you trade against someone who knows more than you do and add the selection is the reason that bit ask spread exists so a market maker doesn't want to be taken advantage of by informed trader they put up a bid ask spread and make back the spread from the regular traders the uninformed traders in amms that's basically the price impact or the slippage to some extent also um the fees that you pay like the 30 basis points are they paying uni swap and what sets blockchains and defy apart from centralized finance is that everything is public right all the transactions that are going to happen all the trades are public and so a toxic trader a hedge fund a high frequency trader doesn't even need to pay um a retail broker you know like robin hood for order flow they can just look it up publicly but um they need a way to implement their trades so this leads to a certain race to you know to be the first and what you see in centralized markets is that um hfts high frequency traders try for very low latency so they go to absurd lengths to just beat everyone else to market right so whoever is first will win the price so to speak so they will be able to buy or sell the entire quantity that's available at a certain price before anyone else can and that is in some sense the fundamental reason that a lot of these toxic trading schemes like front running like after selection like sandwich attacks and so on and so forth they exist because existing trading systems like amms and limit order books um they work on a first-come first-served basis if you're first you are able to buy whatever you want at a certain price you can if there's a mis-valuation you can you know just arbitrage to the max now in decentralized systems the way this works is to basically collude with a minor so in the past you would have you would have had to set up a mining operation or you would have um you would have had to you know win a priority gas auction now as of this year there's something you know which is called flashbots and it's essentially i think an airbnb for toxic traders so they can just rent out you know space in the next block to um arrange existing trades and fill in their their own trades the best way they want and so this toxic trading through flashbots has led to almost three quarters of a billion dollars in value lost to d5 users so that's huge and it's getting bigger and bigger there's been exponential growth this year which is mostly due to the growth in flashbacks adoption now as a few months ago the growth rate is still exponential but at a lower rate that's because you know you can't grow by more than 100 so they have to find other ways to grow um if you look at the breakdown by protocol you know where are traders losing the most and it's obvious that it's a defy but it's actually decentralized exchanges so um it's no surprise that most of that happens on amms because they are the most popular protocols and their mechanisms are not very economically efficient but a significant amount happens on a limit order book the ydx which actually did not become very big until a few months ago when they moved to their own layer too and so this graph is directly from flashbox they're very open about what they're doing and it is since the beginning cumulative since the beginning of 2020 and so it's quite remarkable that the limit order book is um already such a big um such a big place where toxic trading takes place but of course just like in centralized finance and decentralized finance um limit order books don't protect regular traders they don't protect the little guy so to speak and the little guy can actually not just be retail investors but they can be pension funds they can be mutual funds so kind of all paying for uh the winnings of a few very very sophisticated very fast uh variable capitalized traders so what krypton tries to do is essentially to level the playing field so krypton has a mechanism where a latency advantage simply does not matter right it counts for nothing and so the way that is implemented is that rather than executing orders or traits in single bursts like concentrate a certain finite quantity in an tesla point in time it executes float orders as flow over time and everyone who trades at a certain point in time trades at the same price so it is very very difficult to get a speed advantage um two orders arriving in the same block they start at the same point in time so if you want to be first as a toxic trader you would have to buy out the entire block on flashbots which is expensive and that would only give you a one michael i know there's there's a lot to to go over for this um but in the interest of time uh i'm i'm about finished thank you so much patrick thanks i was curious if you're gonna do a demo yeah no no we're not gonna do it i mean it's kind of you can watch the video you can you can check it out for yourself which i actually encourage you to do so uh if you have one blog time advantage with just one second on avalanche you know and your trade goes on for maybe a thousand seconds or something a thousand blocks there's not much they can take advantage of so uh it doesn't pay for toxic traders to be encrypted on so um i'm just in the interest of time i'm just going to skip that um you can you know please check out the demo so i want to say a few words about the protocol architecture so um of course this protocol is i think um fairly economically efficient there's very little that um sophisticated traders can do to take advantage of ordinary people but that comes at the cost of um very high computational complexity for the matching engine for order crossings on and so forth so what we're doing is we're putting all of the computational intensive code off the blockchain and onto decentralized chain link or the nodes this way all that the smart contract on chain does is to process transfer of tokens which is order settlement and kind of update all the structs so it's very very gas efficient and once again that's enabled really by the decentralized network and external adapters and so in digital time i'm not going to go into detail on how this works it's essentially i think a hybrid smart contract um we use merkle trees you know just like the solay projects i was very happy to see that these projects are getting more and more technically sophisticated uh there's certainly a lot of opportunity and so um let me just close by saying that if you're interested if you want to stop being cannon fodder for toxic traders please check us out our website is www.krypton.exchange we have a testnet which is you know really just early proof of concept so no great graphical user interface if you wanna get in touch with us you know join us on telegram our channel is called krypton exchange and here's the invite link so once again you know thanks to everyone congratulations to the other winners thanks patrick awesome yeah uh i saw this and for those of you who are uh who are kind of like kind of trying to follow along and maybe it's a little bit a little too technical basically uh exchanges get front run a lot and so this is an exchange where you can be protected from a lot of this uh this latency issues right so you're not gonna get screwed over using some of these exchanges which is awesome right it's all powered by kind of this this super innovative technology using chain link as a backbone here um so michael so my question for you is simply when can i use this oh yeah so um there's still a lot to do so we want to add some more functionality we need to get the contracts audited which is probably much a much bigger deal since there's also this off-chain code in python um then we need to strike some you know agreements with node operators so this is really as decentralized as possible that's the promise my hope is that probably in the first half of 2022 this should be going live that is incredibly exciting incredibly exciting well thank you so much michael for being here uh huge congratulations and really looking forward to the future of your protocol and what you're working on thanks patrick i truly appreciate it thank you awesome and so that was another one where he said you know you heard him speaking a little bit he was like yeah i kind of showed up to spring and i didn't really know what i was doing blockchain is kind of new and then he just built this this better dex absolutely insane like in six months like he's or maybe he's been around solidity a little bit longer but he's learning solidity he got into us and now he's building these amazing protocols so this is absolutely something that you can do as well so uh we have two more prizes which is dow's and the grand prize however we have a surprise new category that we introduced a little bit late called the off chain compute and don't worry if you didn't apply for it we basically look to see you know what type of off chain compute uh functionality your projects used did they use keepers did they use vrf did they use some kind of really cool off-chain uh mechanic that does something really unique and so we added this new category called the off chain compute category and this was another 15 000 category that we added but we didn't tell anybody so so sometimes this happens in hackathons we have new categories it is what it is and the off chain compute winner is going to be the protocol nft meltdown so nft meltdown congratulations you also won fifteen thousand dollars in link and i believe you're here i believe it's caleb um if i'm if i'm not mistaken i think it's caleb and caleb is there anybody else on your team here yeah we got vasili as well that's right okay great let me pull basilian hello hello welcome patrick hey patrick how you going well huge i'm doing fantastic i'm doing even better now that you're here congrats on your project really cool project um five minutes on the clock to tell us about it thank you what a surprise all right let me try and get this going here i will share my entire screen alright can you guys see that now um so yeah hey everyone my name is caleb and i'm here with vasily we're presenting meltdown an nft candle candle action platform on the blockchain so why did we create another nfc candle auction platform right there are auction platforms that already exist and how they different to existing solutions well back in march of 2021 people auctioned off every day as an nft at the christie's auction house if you guys remember um this artwork actually sold for a record-breaking 69 million dollars however shortly after the auction was finished billionaire justin sun claimed that his bid of 79 million dollars was not accepted on the website due to a glitch um but as it was sold on a centralized platform it's difficult to verify and audit this missing bid but you know this might have cost people up to 10 million dollars and this problem of transparency and auditability on these really expensive and high stakes auctions is what inspired us to make something better you know today nfts mostly represent just artwork and digital assets but we believe that in the future there's no reason why they can't represent the right to any high value property so this could be land or houses so it's quite important that we actually figure out how to sell these things trustlessly and fairly as well current on chain systems are inefficient and also vulnerable to front running and mev extraction and as we discussed centralized solutions although they're efficient um they have counterparty risk and they're also opaque so we created meltdown as a fair efficient and decentralized auction protocol as our solution to the growing needs of nft buyers and sellers so the question may be what is a candle auction and how they help us solve this problem candle auctions were originally used in the 19th century as a fair way to auction ships a candle was lit and bids were placed as the candle burnt down when the flame went out the person with the highest bid at the time would win the auction so we have developed the first nft candle auction system made possible by chain link here's how it works an nft owner can create an auction and specify the time at which the auction will end as well as the length of the closing window so the auction can terminate at any point during that closing window the actual termination point will be decided retroactively using chain links verifiable random functions whoever is the highest bidder at that point will win the nft the loser bids are returned so the users can withdraw them and the nft seller collects the highest bid candle auctions have several advantages that are especially useful in a blockchain environment since nobody knows exactly when the auction will end nobody can snipe the option at the last minute and uh candle auctions are efficient as they finalize in a finite amount of time also meltdown is a non-cryptographic auction system meaning that smart contracts themselves can also place bids on auctions this means that candle auctions are more fair more decentralized and more transparent than other types of auctions so all of these advantages increase confidence for buyers and lead to higher revenues for sellers so i think we're going to show you a quick live demo of meltdown now here you can see it the dap is actually live so you can access it at app.nftml on the coventestnet as you can see there are already a few auctions that have been created these two have already been finalized and this one yeah this one over there is still running so let's take a look at the one that is still live here we go so this is what an auction page looks like as you can see we have the nft on the left on the top left and we've got the bid chart on the right you can see that we also have a two by two bidders represented by these lines and also down at the very bottom and the winner will be decided in about four hours 28 minutes and eight seconds so the red part in the graph is the closing period we talked about earlier and the auction can end at any point in that red section when the auction ends the chain link keeper knows that our watching our contract will generate a random number using chain links vrf service and this will be used to fairly determine the winner awesome so let's actually try and place a bid on this auction uh live let's see how this goes so we'll just press add to bid i've already got some eth in my coven account and i quite like this nft so i'm going to try and bid 0.18 i'm going to hit update bid and we can confirm confirm this transaction coven's been a little bit funny recently but let's see if this goes through we should be able to see that bid pop up on the bid chart here while that's confirming shout out to morales and daptools so those are the two frameworks we used to develop this and here we go so we can see here that we now have this is us 0.1 eth and hopefully we can win this nft so we bid before the closing window so this bid is guaranteed to to actually count for this auction yeah that pretty much wraps us up in terms of our presentation just like to say a massive thanks to um patrick especially i think your enthusiasm enthusiasm definitely made this a very enjoyable experience as well as everyone in the chain link discord uh and the community me and vasily we actually met in the uh channeling discord so um yeah we uh we are definitely meltdown wouldn't have been possible without all you guys um yeah that's it thanks a lot awesome absolutely fantastic meeting friends in the community welcome to black welcome to blockchain welcome to web3 uh absolutely fantastic yeah and this is one of these products that's really cool right because as you said the beginning you're like oh like we've seen candle auctions before but this is much more fair and actually truly decentralized right it's all about truth as opposed to trust so really cool job here um so it's live on coven right now i think you kind of mentioned you were alluding to some uh some next steps what are those next steps for you here so uh the next steps would be l2 of course uh everyone loves lower fees faster transactions and in addition to that just getting the contracts to the point of being really um compatible with other protocols interoperable awesome absolutely well huge congrats once again uh congratulations on winning the super secret new surprise category yeah yeah thank you pressure and really really really excited to see what you both do in the future and really excited to see the future of this project awesome have a good evening you too whoo these products are so sick they're so cool they're all so cool and they all do fantastic things and they provide these services and they give more and more and more utility to this world that we absolutely love and we need to make a build a better future so we have two left two projects left dao and then the grand prize and i know the people behind stage i didn't tell them who wins so they're they're kind of you know they're a little bit nervous as to what's gonna win uh what so let me jump back to the stream real quick um i guess i guess this will be a real quick screen anyways but the dow winner the winner of the dow protocol another 15 000 prize in link token goes to the governor c project i'm really excited to hear governor she talked uh because when i saw this i i i lost my mind i was like this is super super cool um the governor's c team here uh team is here i'm gonna be grabbing them adding them to stream here um i think it's i think this is the team i think it's it's the three of you am i am i missing anybody or did i add somebody add somebody incorrectly um um it's okay i'm gonna present so yeah perfect well welcome to the stream and huge congrats oh my god it's a really great honor to present today yeah hi this is ellen park the member of team governor c and we have four members in our team uh including me also other team members are sangam park england keen and jumuly and all of them are really good blockchain developers so in this project in this hackathon our team developed a smart contract named governor c so this is a fully decentralized severe resistance quadratic voting system based on chain link vrf so recently as you all all know dao has emerged as an innovative organization system for the healthy community governance and our team believes this is a new governance system for the coming websphere ecosystem the key for building successful dao is making fair governance systems so lots of community members can make their voices and lead the group to the better direction to build better dao environment many dell participants try to develop governance voting system in better way so quadratic voting method which make closer purchasing tickets increase exponentially has emerged as has emerged to compensate for the weakness of existing methods like one dollar one vote however this alternative this new method is also exposed to risk of civil attack um by creating multiple accounts several voters with bad intentions can show inappropriate voting power so our team would like to suggest improved voting systems smart contract governor c this is a fully decentralized civil resistance quadratic voting system based on chain link vrf so we are going to release this smart contract as an open source to make our solution fully decentralized we use a lot of existing blockchain services as you can see on the screen to make cb resistance quadratic voting system we suggest a new voting method called probability quadratic voting so in this hackathon in this chain-link hackathon we developed three things first the pqwa method to improve existing quadratic voting system second voting contract system called governor c based on pqv method and chain link vrf last we built a service by using governor c contract we developed so first pqv is a severe resistance quadratic voting system this team developed this method make it always a loose-to-do sibling attack by applying probability element and quadratic voting so this team did a simulation based on pareto distribution high similarity with quadratic voting and civil resistance have proofed and we also found the most optimal hyper parameter based on the simulation um the governor's c charlie is a smart contract for voting system based on pqv we suggested we use train leak vrf to implement the probability factor of pk v to make this open source solution more scalable this contract follows the compound governance module standard which is one of the most widely used standards in dell ecosystem even the biggest dell service sushi swap follows this standard current dows using compound motor based on governor b can easily apply our new solution governor c which is developed under the same standard and finally we develop a service based on the governor's c smart contract so by providing the scalable and decentralized open source solution we want to our the goal of our team is to activating the entire daw ecosystem based on fair decision making system so um before we conclude our presentation finish our presentation we want to show next steps of our project first we are going to upgrade our governor's c contract to the next level our open source project improved compound governance module governor b based on pqv and chain link vrf so this team is going to study other methods which could be governor d to improve governance system second this project wants to expand the usage of pqv to other areas um we showed the demo which is applied which applied governor c contract on governance so our demo is on the dev website yeah so we want to use pqv in several other areas like quadratic funding quadrant ranking and also quadratic attention payment so due to the time constraint um we only we just um delivered just simple ideas for our projects so if you want to see detailed information about project you can check our dev pro website so in in the website you can check the demo video and also our detailed code about the governancy so this is the end of our team governance's presentation so thank you a lot for listening and thank you a lot for all of the sponsors and organizers of chain link hackathon thank you and thank you so much for for participating yeah this was one of those products that i i looked at this and i was like wait what are they trying to do and then i was just blown away i was like okay all my doubt tutorials are now useless i need to revamp everything uh so i can use this new governor c contract to make them even fair even better um so that's actually my question here uh when can we start putting these in tutorials does it make sense for us to wait for um for delta for the next one i know uh if for those of you who are watching they have like a ui where you can kind of go through the service doing it should we wait for governor delta is governor c good to go what are your thoughts there also also after the hackathon we are going to develop more about governor c so it might take about one to two months yeah so awesome so so building governor c to be even cooler okay so we need to connect um uh soon uh so we can talk about you know getting this in the hand to all the dows in the space so they can have you know provably fairer cheaper just better uh governance really really exciting um and some big brain stuff here so thank you so much for being here huge congratulations on your 15 000 prize and just building this really cool thing thanks a lot awesome work all right so that means uh well actually just another another huge you know a shout out there i'm like i i want to get my hands on that i need governor c i need to adopt tutorials in 2022 are all going to be governor c that's the plan um so with that being said this means i think we are at almost the end of the closing ceremony this means there's one project left this means there's the grand prize winner left this is the project that we thought was the just kind of showed the ultimate um chain linkiness the hackathoniness it's just a absolutely phenomenal project here uh we are so excited to show to you what the grand prize is who won who won the grand prize here and oh i gotta let me pull this uh pull this off i've got a little drum roll thing that i wanted to play but i already kind of ruined it by showing the video so the grand prize winner of the chainlink hackathon 2021 fall edition is drum roll please [Music] the music team thirty thousand dollars link token to the music team for their music bonds and they're all here i'm going to pull them on stage pulling you all on sage one by one hello hello you're all here welcome welcome grand prize winners music thank you you were you were backstage for like an hour appreciate the week yeah and that was also we just met for the the whole team just met for the first time immediately prior to uh jumping in to the green room right oh amazing so wait so how did what so you just met how did you coordinate how did you talk before this no i mean the whole so so we're in um yeah i mean five different time zones right so um we've got rob in philadelphia um so i'm in the uk and um deeshan's in karachi in pakistan lagesh is in chennai in india and sharon's in melbourne in australia right so insane but we kind of stuck to a more like asia-centric time zone and then you know rob was able to contribute you know we we lagesh also met rob together and he was able to contribute um kind of um without having to without attending the regular stand-ups right so we were doing basically daily stand-ups throughout the hackathon awesome absolutely uh and uh for those of you who came to the um the speed coding event uh yes that is the sean as well um clearly he was a phenomenal coder there and they built the phenomenal project so just huge congrats to all five of you just a really really cool project here um let's let's go ahead and give you this give you the floor and tell the world about what you built great yeah and thank you so much patrick and um you know thanks to the whole i mean thank you so much to to chain link i think this is this is uh you know your the validation here this is a vote for the future of music right i think that the musicians have been left out in the cold uh by the industry for for so long and um you know this is this is uh this is music coming back baby um you know napster kind of cannibalized the industry somewhat but it gave us all access to all of the music in the world right um and our vision is that web 3 is the music is a foundational building block of web 3 as an asset as a as an asset that has real value that we all love so um here we go uh so this is our this is this is us nft music bonds and we're enabling the creation of non-fungible music bonds to empower artists with financial freedom so there's actually more money locked in d5 that every music streaming service in the entire industry made in 2020 so our vision and what we're doing is building the in the decentralized infrastructure to power the next generation of music enabling music rights owners to get financing from their future income and establishing digital music as a building block of web 3. web3 so what does that mean well you know we're uh we're here with the music bonds so david bowie back in 1997 um was not only like musical fight a musical pioneer but he pioneered um the bowie bombs and um this was an instrument that packaged up um i think 26 of his albums um and then he issued them as a bond for 55 million and those sold to prudential insurance and this enabled david bowie to buy back his the rights to um his his music so 50 of his music was owned by his former manager right and and by issuing this bond he was able to um go and mint go and buy back his music so it's getting late for me here um anyway so here we go so this is the this is the the demo so you can choose a marketplace and um we conceived this as a chain agnostic standard so for now we've just zeroed in on openc and um so you can you can uh go through to uh min on openc and now i'm just going to give a shout out to the uh audience or patrick or whoever can you guys give us an artist who do you want who do you want us to demo right can you i'm watching youtube now in the comments so if anybody wants to shout out an artist then we can we can test it out we can try it out live you know we can see how the uh okay it's print okay that's it it's on it's on cool so this is where as an artist you put in your nft bond information and um basically this what we're going to do is we're going to set this up so you need to validate this through your spotify for artists account so i'm just going to search for prints here and um yeah this is um this is prince but we need what we need is prince's um id right so we're going to have that him that's in there isn't it there we go cool yeah i've got kind of an interesting set up here so here you go so we pull out prince's id and we can stick this in the spotify artist id here right um and you see it's pulled up his monthly spotify listeners straight away and let's search for prints print there you go here we go so we're going to grab the url from print and boom and we're going to give it a name let's call it prince and the symbol well what was that oh it doesn't have a let's just uh go for it i think we've got other so my youtube is just uh playing the music right so so what you can do as an artist you can come in and you can provide a collateral deposit and this this collateral deposit enables us and what enables the um the engine to rate the the bond based on the number of uh listeners and it's the median of the number of listeners and the number of subscribers so i'm just going to go in here and i'm going to add let's go for one e and let's look at the individual bond value so we can use this to determine the amount of bonds individual bonds that are issued right so rather than setting up like a fractionalized uh nft we've we've set this up so it can be minted as a collection so we're actually in uh we're actually going to be minting individual nfps um this is because we started off like minting on openc and it just makes you know it's just nice to be able to see everything as a collection right so um i'd just like to hand over to sharon who was responsible for this fantastic um ui and ux design and maybe she can talk a bit about her process yeah thanks adam um so for the ui we drew inspiration from the image that we had on the landing page for branding and color and use existing ui design systems like material ui for quick prototyping and for the ux it was an iterative process for the team we made many changes along the way as we needed to adapt to how depths function such as waiting for transactions to be processed and waiting for launching data to come back and then displaying it for our users besides getting the input as we can see before um we needed users to also connect um their wallet at the right time so we didn't want it to be premature as you can see we didn't connect um we will connect a bit later on in the next step when we deposit the collateral so yeah we wanted it to be a seamless and logical process as everything in blockchain will eventuate to some sort of monetary involvement we wanted the experience to be trustful and more straightforward for potential mainstream users yeah um thanks adam and sharon so well yeah um we have started out setting up a chain link node with external adapter at texas to take advantage of um this online breakfast for youtube and spotify data um so um collateral pool or an asset pool is the contract where an artist will transfer the collateral amount for every quarter starting with first quarter um first quarter collateral amount deposit right now the quality amount could be calculated from the revenue of these youtube and spotify streaming service that you saw in the previous page um the collateral deposit is necessary here as it determines the rating for the bond so rating and dynamics will be um explained by um sean in the next module but yeah um when the asset pool is set up artists can then meet nft bonds as per their number of bonds configuration once these nfts metadata are stored on ipfs and pin to pinata the art for the nft will be available on um openc for the fans are the investors to um join the collections now um i would like to invite this one to explain um the further processing detail okay so basically uh when uh artist is done with the depositing the uh funds and the minting of the bond what our bond do is our nft bond draws the streaming data from external sources like youtube and spotify using the uh using the chain links oracle so we use we are using channeling oracle to extract the data from the uh different external sources and that data is being used by our rating engine which actually applies the rating on nft bond generally when you to go in the financial market and see a bond you see the rating of a bond and death rating identifies either that bond is an investment grade bond or a speculative bond or the riskier the bond is the speculative the bond is the lower the rating is the risk the higher the interest rate you will get so that's how the complete process is being built and for that what we need to do is basically we need to collect data or information from all different sources which is uh external service like youtube and spotify that needs to be done like in a decentralized way so our idea is are more the plan and what you say a final implementation is to create a complete decentralized oracle network for music streaming data like chan link is doing for uh ethereum price or different cryptocurrency prices so prices are coming from 30 different sources for the ethereum and then they got aggregated at the single place from that single place you can when you fetch get the pricing feed you get the data which is coming from 30 different sources so it is not a single source it is decentralized so this is what we're trying to do with music that we are getting the streaming data from different multiple sources and we will aggregate it in a single place and then the nft bond and the rating engine will use that information for that we had did the quite bit of digging into the how channeling is aggregating using the flux aggregator and the ocr so we actually had to implement flux aggregator by ourself obviously using the chain links implementation but it was the previous version of implementation so we tried to implement but definitely we will need chain links team help to finalize and implement it in a production so that uh this needs to be done with the help because it's not uh supported after the out of the box so channeling teams will be helping us in integrating and creating this option reporting for uh these systems and that these will be integrated into our rating the tao and the nfts and all these information will be coming here so complete or decentralized network for the what you say streaming data which will be additional category for chain link as well that's completely our protocol how we work okay so i worked on uh the visual representations of the actual nft bonds and after some brainstorming we thought that it would be appropriate to use uh fractals to to represent our idea [Music] because uh at their essence a fractal the visuals are really just driven by the numbers and the formulas underneath them so uh we thought it would be appropriate to use the same concept here in that um various iterations of these of these bonds are driven by uh what the artist chooses and how many um streams they're getting and basically all the numbers in the data underneath them um the challenge of course was uh to come up with a way uh to visualize this because an actual fractal is very complex so we came up with a simplified uh version uh using um just a simple piece of music notation um in this case uh just a treble clef and uh so i basically created uh something that's representative of a fractal based on a treble clef and um our idea is to represent the different levels of bond collateralization um using a color scheme with red being um a bond that is what would be like a d rating um that isn't very uh collateralized and then uh as it transitions to green a green bond would be one that is fully collateralized and we were also playing with the idea of using a pixelation mechanic to to further uh um exemplify that uh and it's also a subtle nod to the whole um crypto punk uh nft pop culture thing um and so the we're still sort of uh tweaking this and fine-tuning it but uh the the final version of this would be uh what you see on the right or something like it uh which will be a a cool little animated fractal that that will sort of spin and vibe with the artist's music awesome yeah thanks and um so i've just been going through i just took you out of kind of permission the the permissions hell um but we're still and um on this demo but i'm just uh getting to issuing the nft bond itself um and just so you guys there we go just so you guys can understand the rating engine um and what the bonds make what the bond ratings mean um this is basically inspired by the work of moody's and um you know standard and pores and and basically um you know by calculating the median of the spotify and youtube um the the spotify listeners and the youtube subscribers then um all of the top all of the trouble trip all of the a ratings um reach the investment grade um and these these are all uh over collateralized right so uh the point is we've kind of taken the like these ratings that are you know recognized as a standard in the traditional finance world and um adapted them for the d5 right so um you know by over collateralizing then um you know we we're basically sure that the the repayment is going to happen for the nft holders um so and then the other the other ratings actually these are based on based on the sanskrit the val alphabet um so uh treble i and the i ratings um are for a speculative you and are also speculative but still you know a cool asset to hold right um and um you know there's a market for junk bonds um in itself so yeah i've got through and i've just rate i've just um got some of these oh some of these available and let's have a look so you can see that um we've got the various ratings available and um you know this is how they're visualized and we take these right through to openc um and you can see them listed on openc as well right so um but i think you know for the consideration of time i'm just going to pull up what's next for music so yeah basically um you know we had a lot of there were a lot of really cool ideas going on um in in the hackathon itself and i think at the beginning we weren't we were thinking it was going to be more about building out the oracle network itself and spoofing the oracle network which we could have burned like a hell of a lot of time on um and we did burn a had a lot of time on um but then you know through some advice from zack we ended up just using the any api function to bring the data into the contracts and um and uh and towards the end we can't we realized that you know really the next step is the yield maximizer and and enabling these artists to and the holders to maximize their yield through uh you know d5 protocols right so initially we were looking at sushi and we're looking at the bento box protocol but then you know doing a bit more digging and looking at some of the concepts from d5 2.0 um and you know setting up a community-owned dao that's enabled to um incorporate a music-backed rebasing currency so you know right now even like you know the best d5 2.0 projects are still backed by um dye for example right so you know still being beholden to the fed right um whereas like if if through the dow we can um you know purchase the an evergreen catalogue from a legacy artist uh then this can be used as uh to back the currency itself in order to um ensure a floor price right um so immediate next steps minting the genesis bond which is the first bond uh the first nft bond with an established artist and um getting this dow going right so um really just thank you so much to chainlink it's been an amazing opportunity and we've all learned so much and you know i really take my hat off to the idea of of truth and transparency and being able to introduce this to the music industry is so overdue so it's really my honor to be here today and um patrick i salute you and i think the rest of music we are all stoked absolutely uh i'm absolutely stoked uh thank you all so much for being here and i know uh i was we gave you a little bit more than five minutes here because you're the grand prize winner you know why not um phenomenal job like i saw this in the first thing i thought i was like oh so this is like d5 meets music but like also kind of wrapped in this in this really cool way i mean the fact that you had the bonds be nfts and you can see them on openc i thought was really creative right because that's like a way for um bringing a lot of people into this space right like one of the biggest challenges that we as a web 3 community are facing is just how do we get more people into the space how do we get more people to understand the space and using something like an nft where you have that piece of art it makes it a little bit easier to visualize like what's going on now it's not some random contract on chain okay my bond is kind of this image i thought that was really creative you know having the investment great having the different ratings in the bonds i i thought was was brilliant you know it's a perfect user channel to bring in uh this this new kind of rating um estimator which is totally transparent which is a which is uh phenomenal uh bringing all this data in to kind of create this new d5 vehicle um absolutely blew us away fantastic protocol um you you pretty much laid out your next steps and kind of what you what you've done and i i know i've spoken to i spoke well i spoke to z sean really briefly uh over the duration of the hackathon i i i feel like i don't have any questions because you kind of you all went through and i mean i'm just crazy stoked um you all did phenomenally are there any last things that you all want to say before we uh before we jump off here well i just i'd just like to say that i think that in some ways this whole hackathon like this project is like a proposal for for chain leg right like you know can we crunch music streaming data we need music streaming data for our bonds let us crunch music streaming data and um and and you know you guys i i think you you guys agreed this is this is the next step um for chain link and um so you know and i think this is the next step for for the web um so you know and then i mean that's uh that's all i wanted to say and um you know it's just been you know fantastic to get to know you over the course of the hackathon and um yeah i mean i i just you know can't wait to to roll this out properly in 2022 and um you know please you know join up join our discord um you know get on twitter all of the good stuff music.fm it's there uh you're welcome right this is a community it's this is for the community this is dedicated to transparency in music and um we are moving the industry forward so please join us awesome well thank you all so so much uh absolutely phenomenal job here um i'm gonna i'm gonna slowly close you off one by one because that's all i can do but really excited to see everything the rest of you all do and you know just one more time congratulations thank you
