this is once again probably the most diverse hackathon that we've ever done uh at evk uh and I hope next year you know we're going to have even more people from all around the world joining us uh in wherever we're going to host it 50% of you were new to web tree yet I think this year According to some of the judges is probably one of the best um projects that were actually created from this hackaton so yeah I really have to give you guys another round of applause for doing so well even though you all are so new and again 20% are new to hackathons right so yeah we have a total of $40,000 worth of prizes thanks to all of these sponsors here Mena scroll world coin the graph internet computer psse and Aura so again round of applause okay this year we had a total of 54 projects being submitted for hackathon finalist you win $2,000 per team but actually there's a secret prize for the top project within this five finalists you actually win one Devcon ticket per team member and that's worth up to $3,000 are you guys excited to find out who are the finalists yeah yes all right so the winners are guardian of galaxy just e player love player swipe and shift now the one with the trophy Emoji is the one that won the best prize so you guys are winning one devc ticket per team member all right so without further Ado I'm going to let all of these teams take just five minutes to really quickly present their ideas show you guys why they won and uh what's so amazing about their project so I'm going to first get Guardian of the Galaxy on stage to present ah woo wo [Music] [Applause] all right we we starting all right so yeah hello everyone and um yeah we are guarding Ians of the galaxies and why we're calling that name we want to make the ethereum uh greater again and we want to protect the whole system by uh doing this little uh game here so why do we want to be the Guardians of the Galaxy so we see that vitalic said we must all prepare for an e th FedEd 1% attack so why is that important so like the right now the US have like 31% of all the US uh e state within the E system so we are so close and that number is still climbing up so we are now never before we are closer to the ethereum 51% attack and now we're trying to do this decentralized uh you know this uh Stak in defense game where we simulate the 51% attack within the game play and um we encourage every player to take part in this solo staking process and everyone every player can form alliances and community and communities within the game play and so we're doing what we're doing is like a fully onchain and sustainable game and we are not play to earn but we're play to learn so if is the only token within the game we we are not doing like a game f or anything like that we are purely like a public gos we are trying to educate people with our game and core gam playay is like you start the game you stake the E you collect resources as the representation of your staking rewards and you build communities with your fellow players and then you fight the M together so CL resources form alliances and build communities and what's the most important part here so like in the real life we use the quadratic funding voting to uh vote and fund the public goods that we that we think that can help the ecosystem together like the gcoin you know we have the public goods funding rounds and so we have these artifacts like the sword over there the the artifacts that communities can vote together and use the quadratic funding voting procedure to fend off the mola which represents the ethereum 51% attack so the artifacts being voted there will not only be used for this attack but all but also for the later game play which strengthen the ecosystem by upgrading the network security and decentralization so the game mechanic designs quadratic folding procedure sustainable model and ethereum support and so we're building like an infrastructure for the autonomous world we both are not developers but we really want to utilize this opportunity to learn by doing and we really want to to just uh use this opportunity to uh uh Express what we want in the education model here yeah so here are the team member all I'm the developer and two one is like doing all the gaming design and all the idea ideation of the game yeah so without further Ado let's jump into the demo so uh here is a little game that we have so right here so you're a little spip over there and all the Stars over here is like the G which represents the staking rewards so you have to control this little spaceship over here to collect them and that represents the pending GES over there so this is like the first part you taking part of the game you stake eth and or you collect the resources to represent your staking rewards and the next part is Alliance you want to align make alliance with other players and to fend off and fight the molo together and you paste the other players uh wall address here you propose Alliance and you can accept Alliance from another player and you can all defeat obstacles or fight the molo together so next come to the most important part so the fight part so every every game we will use AI to simulate a molok the details is over here and the question is every molok is being identified with a weakness so all the players uh your alliance your community would have to vote use the quadratic funding voting procedure to vote on a public goods over here and one of the public goods will be most effective for the weakness of the mola so that's the whole game playay Loop you collect you stake you make alliance with other people you fight that's all thank you everyone [Applause] all right wow that project done in three days that to me seems really really impressive so I think we'll go on to the next project we have just e give it up for just Eve [Music] a [Applause] [Music] okay um hello everyone we are just itat and I'm going to introduce y all to what we did so I'm going to start off with the first problem statement which is the current food rating app in our experience is very bad because first uh there are a lot of fake reviews because in Google Maps you don't really need to get verified to leave a review so there are many Bots or ungenuine reviews next will be a lack of transparency as you don't really know if the person has actually dying in at a restaurant before so you could easily fake that as well third would be unreliable ratings so let's say for example a restaurant has like a five star rating it does not really reflect that the food is actually good because it all depends on your food preference as well last would be the centralized platform because for Google Maps uh they can actually take down the rating if the store itself has launched a complaint yeah next so yeah our app is a fot rtic food rating decentralized app with Dynamic voting power powered by blockchain and AI so we use this Dynamic voting algorithm which basically just takes in food preference amount span reliability and we take all that multiply by confidence level and multiply by the rating so this confidence level is actually generated by the aura AI yeah so here is a system architecture we're using nextjs for the front end yeah all right I'll move on to the demo so first you will need to connect your wallet okay then after you connect you need to select at least three preference and your budget range so you actually need to sign the transaction to store this on the scroll chain so yeah we just let it load for a bit because it takes a while sorry yeah it's signing it's signing all right okay now that we're in we can begin our order okay so this is the store Page uh pass it out to Jin okay so every store here is store um in the ICP in the canister so um if the store just one listing they just build a canister and then your store will be inside here okay so let's order a food okay so we proceed with the payment so similarly they will need to sign a transaction to complete the payment yeah so to save time we are going to first type out a review for the later Parts as the signing will take a while right so then next I'll pass it on to Derek okay so this is the review part so first the AI will actually read the review and then it will determine the confidence score based on sentiment and sentiment analysis is like how much context do you provide in this review then if you provide more information you'll get higher score so next we verify with what id to prevent bot spam okay so this is the reveiew like we just ski the part because it takes a while so this is all the reveal that we did as you can see if you provide more context you have more confidence score lastly this is the dashboard for all the shops it's actually the AI will read all the comments on the site there and then if you generate a dashboard VII will actually read your store and provide a summary about your store so actually all the data is been store on chain and then retriev by using the graph and also we also use the graph to pass the data into the AI okay yeah that's the end of our presentation thank you [Applause] all right so that's pretty smart actually so nowadays right you know how restaurants will ask you to give five stars and then you can get like you know free 10% discount or like free coffee or anything now you'll know which ones are the fake reviews so we'll go on to the next project called player love player all right let's give it up up okay hello everyone so let's just get this thing up and running oops okay hello everyone we are team Wanderers so let's talk about dating apps okay so dating apps were created to supposedly connect people and to form U meaningful connections but we felt that the traditional dating apps had certain issues so among the the issues we felt that there was an exploitation on the system so let's say you go on to Tinder you could go you could swipe right on anybody and you could just may maybe just go for like a hookup or something just to get hookups other than that also if you aren't the best social butterfly you would also have awkward online interactions with people you could just say hi and you wouldn't know how to carry on the conversation other than that like the growing in the growing internet age there's a lot of bots and also love scams around so with this issues we uh came up with our game I'll pass the time to jacn all right so our game player love player is actually a dating game but the catch is all the characters are actually real players so how does it work basically when people join our game we will put them into a onetoone scenarios and then they will have to they can have the choices to choose the dialogue to interact with each other so all these are AI generated so in this case we are actually providing a structured and guided interaction so that we can avoid having those kind of um awkward situations and also helps with um I can't remember what but anyway after that so after they go through the game all right you interact with each other you go through the dialogues one by one then you g come to conclusion and you can actually rate the experience so over here we also want to make them commit to their ratings so in that case that will also help our game to have a very authentic R system so that we don't have a scenario where people can just do like a oh I'm going to swipe right on everyone so that I can get a chance on everyone right so in this case let's start with a demo so we have a video here so when people join our game they're going to start with verifying themselves as a from the world ID so this can make sure that all our players are actually just humans like real people so when they start they actually can start to wait for a match so when you get into a match you can see an interface like the usual visual novel game seam kind of interface so you can see on the left side player one can start to talk first and player two can reply back and then player three if player one can reply back with one one of the choices that the AI generated and then you'll go back and forth and come to the conclusion so in this interactions we also actually created like a short story so you can view the story and then you can rate it so in this case here is where we do the committing so when you want to pass or like the interaction right you have actually make a transaction online and on chain so it is just to make sure that you don't give you a commitment so they have to pay for it not just make some random um rating yeah and then in the end if people both match each other they like then we just set them up for the next date and that's all for our [Applause] product man I feel like you guys are geniuses but you know I I've never used any dating app so I I don't know how it works but uh wo wo wo you don't believe me try try and find me but yeah I I feel like now I'm going to have a a madeup fantasy in my head of like going on a coffee date with this person but it doesn't exist then when I meet them in real life then awkward awkward right um but yeah I I also realized one thing web 3ux has been very painful uh everything I want to do I need to sign one transaction So yeah thank God it doesn't have happen in real life okay anyways let's go on to the next presentation swipe [Music] testing testing yeah okay so hello everyone I'm Johnson and is anyone here cold yes okay that's isn't it isn't just me I'm wearing three layers right now okay so today I'm going to present about swipe and to put into three words swipe match and earn okay next so yeah this is our team we have a product design we have a product designer we have um Ai and product engineering research and product he looks so happy I'm not okay next and it disappeared come back okay cool okay let me just continue so the problem statement that we actually identified was web tree is being decentralized but that also makes web tree jobs harder to find so it shouldn't be like that and one really really good tagline that my teammate gave was shitcoins and mem coins are easier to find than jobs so actually a really good case study was from Barra chain they raised over 150 million US dollars but still they have to go to Twitter to find a guy for marketing it shouldn't be like that so next yeah so this is what we're trying to do make job hunting in web Tre easy and fun and let me show you how so you might recognize this UI Bumble T Tinder like okay so for job Seekers and recruiters you can all swipe left and right towards each other so this is kind of like a Vibe check and to see which job offer you really kind uh you really want to take out next so this is the first main point smart contracts for job agreements and payments so whoever has done internship or even have um Rec went on for jobs some people might face issues that hey the company promised to pay a certain amount but in the end I didn't get that amount so this is where we come in we in we instill smart contracts to be used for job agreements and placements so so that you can get your promised and agreed share at the end of the month to Foster trust between two parties next oh the time is scking okay cool decentralized rating system for companies so remember you can swipe left and right right so every time you swipe you're actually affecting the reputation of the company that you're swiping so this is um for us to become a more self-regulated job-seeking platform so um companies that get higher reputation means that they are posting more legit jobs they are not scammed they actually can get higher success rate for good quality hires and moving on next is all our user data are store on chain so they have their own they own their own data as well as uh resistant to censorship next so you remember I mentioned about um you remember I mentioned about you can um store your own store your chain data right so basically uh what we look into web tree is proof of work so we believe that in this in web tree it doesn't your degree doesn't really matter too much it's hey hello go back it's more on how like how much you involved in the community so even if you're involved in mem coin projects you you join hackathons wrot wrote articles and medium go next you can actually um display all of these results to people who go to your profile so as you can see job Seekers can see hey um sorry recruiters can see hey this guy has um how many GitHub projects that are related uh written in solidity and so on to have a more easier gauge on how involved you are in the ecosystem next and one fun thing so to make communities more um entangled with each other we actually created a crypto Persona um I would say AI evaluator so next you can actually put in your GitHub link your Twitter link your medium link and you can actually based on your profile generate your own crypto Persona so whether you're a defi Deen you're a mcoin farm airdrop farmer mecoin enthusiast it all shows up and this is just to promote communities you can share it out get more people on board to the platform next and yeah this is our solution architecture not going to go too deep into it quite of boring I've been staring for this for two days next yeah that's all for today thank you and Swiper no swiping [Music] all right so just now we have dating AI dating app now we have a dating style job seeking platform do you guys realize that both the teams just now are all very young how how old are you guys by the way 21 22 23 24 wow you guys just really stack up huh yeah all of you guys are now all just playing dating apps huh okay so next we have shift let's give it up for testing crazy okay uh all right before I start let me give you a sample scenario he crazy okay M ah look at his found new eye vows I know he did not go to E Global Singapore I'm just giving a sample use case but he went to e Global Singapore next okay so basically what is the issue with if Global Singapore there are too many events clashing with each other do you guys agree yes okay okay but everybody compar if Global Singapore with another certain blockchain event which is done very well I do not want to say that name right now proceed what's the solution next presenting shift by ifu the state just the context next okay so what are we doing we are making everybody take shifts doing events basically we are make sure that they events do not overlap with each other we also doing cool stuff on the site like quadratic funding which is what everybody is doing right now is the current hype so we split this pool into two parts organizers and Community engagement we are also Community platform we let them have bounties reputation reward and penalties basically the reputation part is that we make them adhere to our rules if not they'll get penalize L event funds okay next shifting we are shifting how Community engagement works next okay demo okay okay I hope the demo God is with me yeah right let's see so first of all we want to identify is oh we want to verify that it's a unique human right so yeah I'm using my phone verify and once that is done okay okay you can see the scroll is unscr right now so I need to connect to my wallet to scroll yep yeah and uh we Implement scoll so uh just kidding just kidding right okay so uh basically this is where everyone can see the communities and um so this is how you can add a new community we actually deploy five contracts or on scroll we are all in on to scroll yeah right and of course here is where you can look at the details of like the reputation and how many people State the um community and there are AI analysis that is available here to according to the data that it has it will generate like a fantasy story about it yeah yeah there you go right and the next thing is on event so this is where you can preview of the events by uh where as organizer they can approve event and as a user you can f find the event and of course you can create an event as well so once it's done there will be a new event created here supposing okay so next things is Bounty this is where we Implement something called contribute to earn we want the community to be engaged with the organizers so organizers can actually create a bounty and then uh as a as a community members you can accept the Bounty like building websites or creating posters so this is what we have and the next things is I want to show you let's say I know that today there's a event happening from 9 to 5: so I will just pick the time to show you that there will be a precaution alert that um mentioned that yeah there'll be clashing so this is where the pan Falls in and so the rewards fors in right okay so looking into our solution architecture yeah we have our user our H is here right it's using the website and the nextjs is our main framework and verification is World ID signer is on metamask and all of our contracts is on scroll and for the Gen um LM stuff we have it on Aura and everything is on evm next why did we choose these Tre Skool Aura and World ID next okay so what we are doing with aura we are using the Gen AI capabilities to do poundy descriptions and Community summaries and sco definitely all our contracts are deployed on sco which is used for quadratic funding registration everything you can see over there and World ID basically we want no fake people on our site and we want them all to be real and like those dat dating apps fake people okay no no no no no I mean I mean those fake people who get on to dating apps okay you guys are cool no worries next what do we do to get money basically this a community app so we don't really emphasize on money but they we still need money in everywhere so 1% of platform fees we take from their quadratic funding earnings and bounties and sponsor AI proms basically AI proms in a might need transaction fee sometimes so we will charge them after 10 free and boosting engagement basically we highlight their Community for a fee put their project on fire I know somebody know somebody okay never mind future plans we have plan to have Partnerships with more communities and more chains we will deploy our own native token and we will be the onetop community hub for everybody meet the team we have cool product and fun end people and backend and smart contract smarty boys oh okay yes very good thank you [Applause] all right so I think that's all of the teams right five yes that's all five so yeah um I guess give it up for all of these five finalists I hope you guys learn something from them lots of interesting projects Okay so so the next part is going to be hackathon whoa hecton
