ETHDenver 2023 #BUIDLathon Top 18 #BUIDL'S + Celebrity Judges Favorites

It's been great here at ETH Denver. So, this is my first time in America, first conference, first hackathon. So, everything has been a first and it has been a joy. It was really great to meet all the people in the space. There are so many different creative people doing all different types of projects.

Oh, it's fantastic, amazing, and so many hackers, and I I like to stay here. It's a different experience meeting people in person and you can get questions answered a lot easier. So you can kind of get the inside scoop when you're over here talking to people in person. Coming out here to eat Denver is just this incredible opportunity for us to meet with developers and help to bring the tools that they need to to make this world even better. We are, you know, just um kind of like having a social awakening and I believe that this is going to be huge.

I enjoyed building on a project with you. That was very it was a great experience and I look forward to my next hackathons. Guys, we're bringing to the stage someone you all know and love. One of the founders of ETH Denver, my favorite person in the whole world. He took a chance on me and I just love John.

He takes a chance on artists, creators, developers, investor, literally anyone. I mean, can I have a round of applause for anyone that knows John and what he does for you? John is changing lives. John changed my life. Thank you for having me.

I love you guys. Make it loud for John Peller. [Applause] All right. Can I get my slides up? There we go.

Welcome to closing ceremonies, folks. Did y'all have fun? What the hell was that? Did you have fun or what? That's better.

I mean, my my favorite part is like right now thinking back while everything's fresh, maker space, arcade games, biddler houses, conversations, the shill villages. I mean, my god, did you get lost? I got lost and it's amazing. So, we're going to talk just a little bit about some housekeeping and then I'm going to hand the mic to Jason. Uh, we're going to get this the projects up here, which is actually what we're here for, not listening to me talk.

So, GM Bufforn friends, did y'all enjoy the year of the spork? Y'all going to come back next year? Anybody want to guess what the character is going to be for next year? Anybody? What?

Narwhal maybe the year of the spork well folks. So what this means the year of the spork whale is about it's about ownership but contribution. So we don't use the word VIP anymore. Spork whale is an earned thing. Now you can contribute economically but as a contributor as you earn more spork you become a deeper and deeper owner in the ecosystem.

So if you remember we're a cooperative we're a Colorado cooperative DAO and the unit of account that we use to denote the ownership is the spork token. So for everybody here remember to claim your spork when that comes available because that denotes your ownership in the DAO. So next year we're going to be talking a lot more about this notion of ownership, contribution, and participation in Dows and what it means to become a Sporkwell in the Sporkdow and ETH Denver community. Now, in a second, I actually didn't quue it up, but I'm going to do this. I'm during the presentations, I'm going to pick somebody who's going to get upgraded to VIP status.

If you like my tweet that's going to come out in like 1 minute, follow me, like and retweet and you will get upgraded to hang out at the afterparty, the closing party VIP with me. Now, a little foreshadowing alpha here. Now, the Denver community is global. 115 countries represented this year. Lots of people.

But not everybody can come. Visas are hard. Travel's expensive. Everything costs a lot of money. So, we are going to be exploring Bidd Europe and Biddle Asia.

So, it may happen this year. We're currently negotiating with some countries and building partnerships with the state of Colorado and those countries to actually have some cross-pollination happening. And we'll pair it with Sporkfest, which is our innovation festival, and it will be owned by you. So the spork dow community will own these events in addition. So more to come on that.

So um when it's all done, what'll happen is Denver will be called the Super Bowl. It's kind of a fitting time of year. And then these other events will be sort of feeder events to give more access to people who aren't able to travel. Now most importantly, everybody knows the internet sucked, so you can tell us all about it. We did end up fixing it eventually, but a little bloody late.

Um, but in any case, uh, we do want to hear about how we can improve. So, it's a one question survey. Scan it right now. Please go in and actually, it it's super simple to do. Give us your feedback.

Tell us how you think we might be able to improve. Do you like the venue? Do you like the food? Do you like the environment? Do you like the art?

What do you like? What don't you like? We're happy to hear all of it. We do look at everything. So, don't think that we don't care.

Um, because we do. Last year, for example, we heard about long lines and shitty bathrooms. Excuse the pun, but if you were at Eat Denver last year, you know what I mean. And, uh, this year it's going to be something else. The internet didn't work so great, so please tell us about it.

You don't need to be mean, but we know. Um, and whatever else. So, no holds barred. Feel free. Let us know how we're doing.

Closing party tonight is now it's happening right after this. We're going to do a quick changeover and it's going to start almost immediately. The lineup musically is insane. The building will still have some activations going on. I ran into Gerala Chance downstairs near the Doge car and the Bufforn Bidd Brigade lounge.

There's going to be some DDP happening down there about 5:30 and there's going to be all sorts of other cool stuff going on. So stick around. It's going to be a ton of fun and we're going to go uh pretty late so we'll see you all there. And last but not least, you know, I'll just share my thoughts on this like listening to the stories of how Ethmber changes lives. It's why we do it.

It's the reason why we do it. To give people the creative space and the opportunity to express themselves in a way that's meaningful to them is why I get up and do this stuff. because trust me, this is a lot of work. And thank you to our stewards, our meta- stewards, our crew, volunteers, security staff, everybody that put this thing on. There's over 600 people on staff that put this thing together.

So, please a round of applause for them. So, I have to say I, you know, I'm a a a heavy critic of events. Imagine that. And I I travel around the world. I go to conferences everywhere.

There's a reason why we don't call this a conference. We actually prefer the community innovation festival vibe. And I have to say, this year did not disappoint. And it's not me. I just put up the tent and allow people to come in and do their thing.

But another round of applause for you because the vibe in this building over the past four days was special in a way that means a lot to me. So thank you for your own contributions and I'll look forward to doing some more with you. So that's all from me. I am gonna give the microphone to my friend Jason Lee and I'll say it again. I said this at Biddley kickoff.

Jason, thank you for not dying. Congratulations. This is probably the hardest working man in the building. The hackathon, the biddilathon as we call it, is probably the most difficult thing to manage. The moving parts and pieces, the fail points, the complexities, the technologies.

Good job, dude. So, thank you so much, Jason Glee. Please give him a round of applause. And with that, this is the last you're going to see of me. So, another round of applause for that.

And I'll see everybody at the afterparty. Jason. Awesome. Do your thing. Got it.

How you doing? Did you guys have a good week? All right. Cool. So, uh, we just wrapped up the first round of community judging.

We had 95 judges participate in judging all the projects. I'm going to kind of go through a recap of what's about to happen and then I'm going to call on um all the different teams that are participating in our closing ceremony. Um so actually I'm I'm going to flip that. If you know that you are in the top 18, yes, we've switched it from top 15 to top 18. If you could move over, Derek has his hands up high in the air.

if you know that you're a part of the top 18, if you could go check in with him. We're going to start getting you guys in order. That way when I'm done, uh Danny can do the intro and then we'll uh get right into the projects. All right, so total prizes for this year, we ended up with $1.3 million in bounties.

Um we had 180 bounties total that came from all of our incredible judges. Um so thank you to them. And then in addition to that, we had over $2 million in uh investments that are available to different uh projects that participated in this year. So pretty impressive in regards to where we were last year. So what is the second round of judging look like for tonight?

So it says top 15. We actually decided after watching all the infrastructure and scalability to actually add three additional teams to participate. So that's actually now top 18 teams for round one were advanced to the main stage to present in front of our upcoming celebrity uh panel of judges. So you'll notice up here there are two stages or two podiums. Podium one, one team will be presenting and then the second team will be getting ready.

If you've ever attended Warp Tour, it's it's pretty similar to that. Um the way that this works is that each team will get two minutes and 30 seconds to pitch their idea to the judges. Judges will ask questions. Um and then the the teams will answer. So we'll move from there.

Then the top five celebrity judges that we've invited to participate will pick their favorite team that has presented and then each each team will end up winning an additional $1,000 in cash prize as well as just uh general recognition. So the way that track prize pools work is that there's $15,000 split among all participants within the project. So in this case as an example the NFT track say has three participants or three teams each team will get $5,000 whereas the infrastructure track will be split between the six teams that made it to the main stage. So collectively across the the spectrum of what we had this week we had 426 projects that were uh created on BBox. of that 360 actually submitted their project to Biddbox and then we had 95 incredible judges participating and if uh I there's so many light bright lights out here but uh super thanks to uh Don Ho uh for his help in uh putting that team together.

All right, so I'm not going to go. You kind of got a little sneak peek, but um so here's what's gonna happen. I'm gonna pass it over to Danny. If everyone uh enjoyed the content that happened this week, Danny is our head of our content steward. She is responsible for all the stages that you got to participate in.

She's an incredible human being and she also helped put together our panel today and she's actually going to introduce them all. So, give it up for Danny. Thank you. Thank you. I actually want to say that this is a labor of love and it is most certainly not just me.

I want to say thank you to our 37 curators who volunteered their time and energy being OGs all across the ecosystem to bring you this extraordinary content. So Ethan is a community project built by the community. Uh so thank you, thank you, thank you to all our curators. We appreciate you so much and this wouldn't be possible without you. Yes.

Okay. So, I'm going to introduce your celebrity judges. But right before I do that, we're actually going to tell you who the finalist projects are. So, for impact and public goods, the finalists are Sesame, FunPG, and Crypto Credit. For the infrastructure track, the finalists are Bitcoin Vitalik's Vision, BBV, Swappy, Slang, Reentrgency Proxy, Rhinestone, and Inheritable.

Woo! Congratulations. Um, for the uh Metaverse, NFT, and gaming, we have uh Bazer AE2, My Mule, and Synesthesia AGF. Congratulations. Um, for DeFi we have ZK, POX, Tribe.

credit, and Gastly. Congratulations. And last but not least, we have for Dows and community, we have Denoted, Member, and Govlocks. Congratulations to all the finalists. Coming up next, we have our incredible five celebrity judges.

So, please join us on the stage. Molly McKinley from IPFS, Griff Green from Gth, Chris Gilinski from Niche, Evan Vaness, Ethereum, and Sandy Pang from Scroll. I'm going to ask you all to start by uh telling us a little bit about you and about your project. Griff, why don't you kick us off? Sure.

Oh, wow. Thank you. Uh, so my name is Griff Green from Gith General Magic, DAP, Node, Common Stack, Token Engineering, Commons, I don't know, a bunch of other things. But my main focus is how do we make nonprofits profitable? It's just horrible.

Nonprofits are creating value and I'm firm believer. Thank you. Yes, nonprofits create value. What the is with the nonprofit label? like we can we can build economies and economic models for nonprofits and this is what I'm focused on and all my projects are related to [Applause] my name is Molly McKinley.

I have lost my voice from talking to so many amazing people. So, apologies while I whisper all of my judging questions. Um, but I work on IPFS and Falcoin. I'm here talking to folks about the amazing things they're building on the Falcoin virtual machine which is launching in nine days now. Um, and I'm super super excited to see what everyone has built here.

I'm just pumped for people who are building new web 3 infrastructure ways of making humanity's information kind of more accessible, more useful, more persistent long-term, more resilient to all sorts of faults. Um, and I really think that the infrastructure folks are building here is going to power the web for many, many years to come. So, I'm pumped about that. Hi everybody. My name is Chris Gzinski.

I'm CEO of Niche. It's a web 3 social network. Uh before that, I was uh one of the co-founders of Tinder. Uh was one of the inventors of the Swipe Patent and I co-created Bumble as well. So, I've I gotten to talk to a lot of uh people and heard some interesting dating stories.

So, I'm going to say I'm sorry about that. Uh I did my best. Um but now we're I'm working on a company called Niche. Uh it's an NFT gated DAO um that's in the disguise of a uh a membersonly introspace club. Uh where we call ourselves web 2.

5. Our goal is mass adoption bringing web 3 to the billions of people uh that are using legacy web two platforms. [Applause] Howdy y'all. I'm Evan Vaness. I'm probably best known for being the founder of weekend athetherumnews.

com which as you might have guessed is a weekly newsletter about Ethereum. Uh and I am uh sort of between projects right now trying to figure out what I want to do next. And so you know it's like an existential crisis. [Applause] Um hello everyone. My name is Sandy.

I'm from Scroll. Um, we are a ZKevm layer 2 project working on scaling Ethereum. Um, we're not trying super hard to be the first ZKVM, but we are trying incredibly hard to be a community first ZKVM and that means being open source from day one, building with the community and um, and also we like to hold ourselves by the highest standards possible when it comes to diversity and um, various other metrics. So, thank you for those that hacked on scroll this week and for those that didn't, I won't hold it against you. We're incredibly neutral.

So, looking forward to everything you've built this week. Wonderful. Thank you so much. We're so excited to have you here today. And collectively, you're going to pick our top five winners.

With that, I'll pass the mic back to Jason, who's going to introduce the first project. Thanks, Denny. All right. So, we're going to start off with the impact and public goods track. So, uh, this is all for Griff.

So, um, all right. So, the first two teams or the first three teams that are going to be presenting, we have Sesame and then we have Fund PG and then we have Crypto Credit. So, if we could please get Hello everyone. How we doing? Yeah.

Oh, it's okay. It sounds like um who loved the Wi-Fi this weekend. My hack relates to that. So hopefully it should help fix that. I'm going to start I'm going to start pitching it.

So what we built, it's called Sesame. So I have a teammate who's not here, Ellie Faresi. She's a CTO over at Bellow. And what we built is called Sesame. It's SMS ETH to me.

This allows you to use Ethereum without the internet. So this is a wallet that sends your transactions through SMS. Oh, it's over there. We got it. And this is Sesame.

Let me make this full screen. Awesome. Uh, so if any of you are familiar with burner wallet, that's a project that came out of ETH Denver a few years back. This is basically burner wallet plus. So when you arrive, you don't have to know about passwords.

You don't have to know about seed phrases and you get a wallet. This is your wallet. This is a real wallet right now. It is actually checking the balance these checking the balances on all these networks. If you go offline, it maintains the state.

When you want to send a message, it's as you'd expect a bunch of different drop downs. Let me paste in. Let's pick an ETH address from my history. This one looks good. And we'll send this one.

0 classic demo gods. Pretend like you didn't see any of that. We're going to send this address 01. But anyway, to cut to the chase, what this does right here when you slap send pops you open SMS. This is the SMS message with that signed transaction.

The private key never met left my computer, it is offline friendly. We use service workers so that if you go offline, the entire web page still loads. The reason we chose a web page instead of a mobile app, there's a lot of tiny Android phones out there in emerging markets. So, if you're somewhere with slow internet, you likely have a low bandwidth device which cannot store much. And to download an entire app is several megabytes.

A website like this is around 100 kilobytes. So that's an order of 100x less code. And that's Sesame. I can answer any questions. It's ready to use today.

Please don't use it on main nightet yet. You will very likely lose funds because this is a wallet that was made within the last few hours. And thank you everyone for the time. [Applause] So what's what's your desired use case? like you said low how would how would people in low-income countries use this exactly like just to send money for commerce or any other concepts?

Yeah. So I think the target market for the MVP you see right here is remittances. So the idea is you have very low volume maybe once a week once a month you need to send a transaction but you don't have access to the internet often if ever. So assuming you can load it once live you cache all of the data locally. It all happened in the background just now.

Uh, and then you can just send out a transaction when you're ready. Very cool. Amazing project. Great job, Sesame. Thank you.

All right. Am I good? Okay. All right. Let's uh bring up fun to PG and then um let's get the next team up and ready as well.

[Applause] Hello. Hello. How are we doing today? All right, we'll make this quick. We've all been here for a very long two weeks.

Uh so let's get right into it. So, we built is called Fund PG. It's a little initiative to fund public goods. I originally work at uh the Gitcoin partnerships team uh where we we do a lot of top down funding of the Gitcoin matching pool. What was that?

All right, this one's working now. Let's go. Even better. All right. So, what what we're trying to do is bottom up funding of the Gitcoin matching pool.

Uh so what we created here today is a little slider uh so individuals can allocate a percentage of their yield back to funding public goods. Now how do we do that? Let's get on to uh the product. All right. So how we do this is to create a no loss donation pool for the purpose of Eve Denver.

We've integrated with the Ave V2 lending pool. Um and yeah, the vision for us is to really partner with many other Ugenerating products for us to make it easy for users to allocate a percentage of their yield towards public goods. So over here we have our demo. Um it's a very simple product, but sometimes the simplest solutions are the best. Well, it simply involves uh connecting your MetaMask wallet.

You can approve a token amount to transfer into the pool. And what happens after that is users deposited amount uh can choose the amount to deposit and how many percentage of their yield they would like to allocate towards public goods. So for our product road map the first thing we want to do is to create a factory contract. So at the moment for Eve Denver we've only integrated with a but we really want to make it easy for any protocol out there to integrate with UNPG. And secondly, we want to have off-chain analytics.

And what this means is we are emitting events of the amount of yield which users have donated. And this there's many composable use case that we can build from that. Um, for example, we could track the most charitable donors. We could be, you know, utilizing zero knowledge proofs to kind of allow users to prove that they've donated and we can potentially use this for tax deductions. Finally, we also want additional integrations to make it easy for anybody to deploy a pool to defund their specific agenda.

In our case, we've worked most closely with Gitcoin, but we also want to make it easy for any pool to um turn funding from a top- down approach towards a bottoms up approach. Finally, our team, uh, this is Luchano over on the side doing BD and operations. My name is Joseph. I did a smart contracts and back end. And we have Dylan who did most of the front end.

Thank you very much. And please follow us on Twitter at funpg. Now, there is one last thing. I did a little collaboration with Creatures World and Gitcoin. Uh we made these shirts for ETH Denver specifically and they're very limited.

100% of the proceeds goes to funding public goods. [Applause] Awesome shirts. I had a quick question which is um I I'm curious how you've thought about all of the people who are participating and putting resources into these public good pools showing them or and giving them a feedback loop for what they've actually helped create on behalf of this ecosystem because really you're investing in the future growth of the entire space and so making that kind of like a a like a regenerative cycle for us all. Yeah, for sure. Thank you for the question.

So I would say that that's kind of something we are working on and it would be within what we want to do of off-chain analytics as well as additional integrations. So one thing we really really want to do is to have a dashboard that anybody can come onto our website you know see who exactly who has contributed where and from there we can build many many more use cases and we can partner with individual protocols individual projects to really build these entire ecosystem make it normal normalize putting these funds towards the community putting it towards building all these additional use cases that anybody can build on top of. Totally agree. Thank you guys so much. It's awesome.

Awesome. Thanks so much, guys. That was fun. PG. Up next, we have Crypto Credit.

[Applause] Hey everybody, we're Crypto Credit and our purpose is we want to bring cash transactions on chain. So, let's get into the problem. Only 23% of the world has access to credit. 65% of people have access to a bank account globally. If we look at Africa and Asia, they take up about 70% of the world's population and most of those transactions are done using cash.

So here's our solution. We uh crypto credit is a system to create onchain credit using off-chain transactions. We use a validator network to validate all the transactions for cash payers and we incentivize vendors uh and payers through u lending platforms such as Huma where they can borrow against their invoices or they can uh factoriize invoices that they uh they send to other people and we are uh because 90% of the world is on mobile we are a web 3 uh DAP that is mobile first. This is our application. uh anybody in the crowd can actually uh scan this uh QR code and then get access to our to our app immediately and check it out.

Uh just a little breakdown on this page as well. Uh the the oh the thing on the the the thing on the left uh the left hand side is actually the profile where you can check where the user can check their credit and they can see the impact of the invoices being generated as well. And then uh on the left right hand side we have a spectral credit score that can be generated uh for any user on the on the platform. Now we're going to go into the process of it. The service is provided by checking first the credit score and if the user is credit receivable then the terms are determined by the vendor.

The invoice is signed by the payer. Terms are agreed. Then you can use your invoice to go to the lending business human get factoriization for your invoices or s your invoices and underwrite your credit. Then the invoice get paid and when the invoice get paid it stacks into a full credit score that can be uh to pay the centralized system. All right let's get into our stack.

To pursue such an impactful mission we knew that the backbone of our project would need to integrate with the best of what web 3 has to offer. All right. And now onto the future. Crypto Credit's first step into the future would include partnering with businesses to extend their validator network and bring Crypto Credit to the future. All right.

And that's all. And before we end it, I just wanted to say I'm Nigerian. I'm also from Ghana. I'm from Peru. So our people need this.

Yeah. This is a personal this is a very personal project for us and everybody like us around the world. So yeah, I I very much I I'm I'm not I'm from the States, so but I also need this honestly. Uh as a nomad, it's hard to get crypto for cash and I don't really like the banks. So I'm a big fan of this project.

Well done. Uh how does the validator network work? Can you talk about that for 30 more seconds? Absolutely. It's kind of a hard problem to solve because we're dealing with cash transactions.

But we uh through the through our system, we have a uh a validator system where a validator has to stake 10x whatever he's he's able to uh whatever cash transaction he's willing to um basically validate. So there's an incentive for people to try to prove that the validator is actually uh committing fraud or or or anything like that to get the the bond that he has to put up. So there's there's players at play that are actually trying to force people to be honest participants. But how do you validate a cash transaction? So So that's a great question.

It has to do with just being present at the at the transfer. Okay. Um so an individual has to be actually there to watch and and validate it. So yeah. So interesting.

Okay. Very cool. Very cool. Thank you so much. We're out of time, but thank you.

That was an amazing project. Thank you guys so much for your work. Awesome. Thank you. All right.

So, that wraps up our impact and public goods track. We are now moving on to infrastructure. So, the first team that we're going to bring up is Bitcoin's Vitalics Vision or BVV and then we're going to bring up Swappy after that and then Slang and then we'll we'll move on from there. All right, thank you. Good day.

How's uh how's everyone going? Yeah, sick. Anyway, uh we're Bitcoin Vitalics Vision data availability on Bitcoin aka Satoshi's modular stack. So, let's rewind the clock back 60 days. Ordinos was on everyone's timeline.

Every every time I scroll past on Twitter, it was ordinos orals ordinals. So, apart from NFTs and Bitcoin, could we do more? one instead of what if instead of image data we put on Ethereum call data and we call it blob space for all uh not an original idea this is from this handsome gentleman over there a sovereign rollup on bitcoin okay so in case it's not obvious we forked the optack bedrock and we replace the SVG image data with the call data from the batcher and then in turn uh verified that the trans bitcoin transaction was included with an SPV uh light client. So we'll have a look at the lower level architecture. Um so most of the modifications to the OP stack sort of came within the batcher.

we were replacing uh the portion that sort of posted call data to um what would typically be Ethereum with a like Bitcoin client and we were posting them in effectively um unspent tabscript outputs. So uh this is smaller than I thought it would be but this is some log sort of like showing what we were actually doing. So um that big blob of text right there that is some call data that we um take and we compute the tapcript commitment for uh that that transaction gets committed uh to the network and um once it gets confirmed we can construct a tapcript spend transaction and reveal the script that it was like a being tweaked by uh and put that all into the transaction witness um on chain. Um and yeah, like once you're able to post that, you can sort of see that there's an entire transaction. Your whole um sort of call data is now um technically onchain on Bitcoin just within the witness transactions itself.

Um and yeah, this is what a script looks like. It looks very very similar to the ordinals scripts. Um it's just like opt true, op false, and then like a no no execution uh for anything that comes after that. So it doesn't mess with any other scripts in the path. times.

And for validation, we built an onchain um light client that runs in the EVM to validate data and for fraud proofs, etc. And we wrote a Bitcoin library inline assembly. So go ahead and use it for your description projects want to. And yeah, that that is really awesome and totally thinking out of the box. Um and very topical as well.

Um, I think I have a genuine question which is like I've never hacked on Bitcoin before. Like what's the biggest difference kind of building on protocol level for Bitcoin versus Ethereum? It's really it really sucks to build on Bitcoin. I I remember when we were trying to figure out how to decode the proper like TypeScript out like things. There were like four different transaction types that all did roughly the same thing like uh pay to public key, pay to public like script hash, pay to tap routt, pay to tapcript.

I they're all slightly different. Don't know why. I also hate that everything's little Indian so you have to like reverse everything all the time. I don't know why they decided to do that. I guess like Satoshi did it and they're like we can't change it.

This terrible. Yeah. Thank you guys. I hope this is the beginning of lots of fun activities on Bitcoin going forward. Awesome.

All right. Up next we have Swappy. By the way, we're looking for a couple teams in the infrastructure. So, let's just make sure we have on deck we have uh slaying, re-entrance, proxy, rhinestone, and inheritable. Make sure you are checking in with Derek.

He's raising his hands. He's 6'2. You can reach him. All right. Hey, what's up y'all?

Um, I'm J Mill. That's Fig. And we have one more teammate who had to catch a flight pilot. So we built swappy which is a way to execute crosschain swaps by describing them with natural language and it's built on XLR network the squid router and chat GPT. So we can start this out by saying swap 0.

02 02 AVAX on avalanche for.5 Madic or Madic on Polygon. So we run that swappy will fetch and here we get our swap. So it knows we want to sell AVAC on Avalanche and we want to buy Madic on Polygon and then the Squid SDK is giving us the exchange rate. So then we can click swap and actually send this off.

So if it's not if you don't describe it all the way. So if I just say like sell 0.02 Avac on avalanche can run that. So Swappy knows that we want to sell but doesn't know what we want to buy. So he says we need to know what you want to swap your AVAC for.

So you select a chain. So some arbitum ETH. We get our conversion. Same kind of thing. We could execute that.

And then we could say we could switch it to buy and it should switch it to the other side. So that's Swappy. [Applause] It's simple. It's easy. It's accessible.

Like I don't know if I have any questions. You guys have did a great job here building something that is super super easy to use. I guess maybe talk about a little bit more about what contexts you see this being super useful in and what maybe potential integrations you might make between Swappy and other tools to bring this ease of use to others. Yeah, for sure. So, you know, I think we're kind of in the second generation of language model business where it's like we found that it's really good at turning unstructured data into structured data and you know, blockchains, contract calls, like all of that is structured data and you can describe what you want to do in language, but it's kind of a big disconnect to go from that to like actually executing them.

So, you can imagine building out complex transaction paths. Um, you can imagine somebody who's not familiar, you know, it's like you hear about a token, you want to buy it. you know, right now you have to figure out what chain it's on, what decks you can buy it on, you know, such. And so this kind of, you know, with a crosschain protocol can figure that out for you. So I think these are some of the use cases for that we'll see in the future.

And just like I'm really optimistic about interacting with the blockchain just using the words we use in conversation. Awesome. All right. Up next we have rhinestone. We are also looking for re-entrancy proxy.

If you are in the building and you want to present, please make your way to Derek. He's waving his hand. That's my cool. Um, hi everyone. We are rhinestone and over the last week or so we've been building a modular implementation of account obstruction on Ethereum.

So kind of currently in the account obstruction landscape it is still pretty early but there's already a couple of problems. So there's a lot of vendor lock in. So for example if you have a safe deployed it is very hard for you to switch to an argent front end. Um there's lack of customization for the user. So the user can't really choose what features they want and what features they don't want.

There also knowledge barriers and a lot of engineering work is duplicated because different teams are essentially building very similar infrastructure when really they should be focusing on building new features for the users. So the dream solution to this would be a smart contract wallet that is simple to use, custom, so the user should be able to choose the features that they want and the features that they don't want. and it should be modular making it easy for the user to switch out features later on, add new ones or remove existing ones. So in terms of the infrastructure um as as far as we know we we've been the first team to combine the diamond proxy standard with EOCC 4337. Um we modified the diamond contract standard to basically allow us to have a number of stateless plugins that can be deployed to chain once and then reused by every um consumer smart contract wallet.

So the user needs to deploy the diamond contract uh diamond account which holds diamond storage and points to the plugins. Later on they can just add new plugins or remove existing ones or change state variables to change how those plugins work. The same is true for user interfaces. So user could for example decide they want to interact through a meta mask snap but also through session keys and alo also through a web um interface. So now I'm going to show a quick demo.

Um here you go. So this is the front end where on the left side you have a lot of plugins in different categories such as interface, recovery, banking, gaming, whatever you want and then you can just drag them uh drag them over into your wallet. So for example, here you can see a retirement plug-in that basically allows the user to configure a vault where a certain percentage of their income is transferred to and that kind of becomes their pension. So the user just adds the vault address, adds a certain percentage, saves it, and then in this example, we just deploy the wallet with those two plugins, counterfactually deploy it, so the user doesn't have to pay gas up front. We've also gone ahead and instantiated it in this case on polygon but we've also deployed to numerous other chains like scroll and ck sync and here you can see um matic is transferred and then that fraction so 5% in this case is then transferred to the world.

Um that that's it. I hope you enjoy our meme that we've been spending a lot of our creative energy over the last week. UI UX question and thank you to our sponsors. Thank you guys. I think this is really awesome and love to see more implementations of account abstraction and and pushing the frontier forward.

Um I feel like I need to ask a UIUX question. Um I think part of the goal of the whole community is improving UIUX, right? And obviously there's a whole ton of like big brain problems being solved at the program level. But do you think the UIUX is unduly complicated for this particular hack? Yeah.

So we essentially wanted to build the ecosystem where you can have an open source ecosystem of plugins that's similar to an IDE that has extensions or an app store that has mobile apps. How we actually envision the UX is that there would be presets. So for example, you could have a gaming preset that has session keys and NFT lending and whatever other plugins you would need and then a gaming DAB could onboard people with that preset. But then later on the user come can come to a front end like this and say but I also want this preset and I also want the retirement fund and I also want um other kinds of session keys and customize that later on. Great.

Yeah, fantastic work guys. Thank you. All right, up next is Slang. Again, if re-entrance proxy is in the building, if you can please make your way to the stage left, that would be great. Go ahead.

All right. Uh, so my name is Connor. This is John. Um we took a break from building intuition this week to uh work on some dev tooling um to uh approach a problem that we've been encountering a lot while we're building um uh particularly in the decentralized data storage area. Um so we called it slang.

Um and I would like you to meet John. Uh John is an NFT collector. Bought an NFT last week. Um, the bad thing about that is that the metadata for that NFT is stored on a centralized server. And uh, unfortunately that server host just decided to stop hosting that server this morning.

He hasn't found out yet. Uh, he's still very happy. Um, but his NFT is just gone now. Um, so why did this happen, John? All right.

So, I'll admit it's a pretty contrived example, but um you know, it does make me sad to see that so many people will be preferring uh centralized solutions for data storage and tooling rather than uh you know the more decentralized and uh trustless solutions that we have in web 3. And I think I think a lot of that choice is due to uh poor Devx and poor UX. So, I really aim to solve that. Um we really aim to solve that with a lot of uh you know code generation and tooling. I mean let the computers write the code so you don't have to right.

So our particular experience is with ceramic um and a lot of it has to do with um deploying the models as well as generating all of the code integrations uh clients around them so that you can interact. Um and so Slang takes care of all that in one simple CLI command. So all you have to do is define your data models and Slang will just immediately generate the client, the types, everything you need to interact with a web two quality stack in less than 30 seconds. Um and so you might ask how do we do that? Well, we stand on the shoulders of the giants before us.

So um we take advantage of compos um which is postgressbacked but as well as ipfsbacked uh data storage option as well as prisma um which takes in a postgress schema and generates all of the tooling from it. Um in addition uh to make things really easy and offer a lot of options also done some integration with DIDs uh PKPS and lit actions to sort of make a mock uh web 3 AWS or cloud stack uh that hopefully offers pretty equivalent UX. So stop. Super awesome you guys. Um, I know you guys didn't quite get to finish there, but I'm curious also like whether this is, um, supported for things like dynamic NFTs, um, kind of like, you know, access gated NFTs, private NFTs.

You mentioned integrations with LIT and other, um, tools there, like what has this unlocked for, you know, both developer ease of use and the NFT applications it supports? Uh, sure. Yeah. Um, it absolutely is able to support dynamic NFTs. I I don't see why I wouldn't.

And then um yeah, as far as like encryption um we're absolutely able to encrypt um any data streams and those are owned by the user. Um so that's really cool. Uh yeah, there's a lot of capability built there and uh it's not just NFTs that you can store on decentralized storage. Totally agree with that. Thank you guys so much.

It's awesome to see what you're building. Awesome. All right, re-entrance proxy. Last last call. Up next, while we wait, we have an inheritable.

[Music] [Applause] Let's just quick check over here. Move some screens around. See if this counts. time. All right, last second.

Great. That's good to go. Hi, we're team inheritable. I'm Omar. I'm Zeer.

I'm Paul. And we use weavechain and base protocol to create web 3 wills for secure decentralized inheritance. So our stack uses weavechain to expose security functions with simple API calls like building verifiable Merkel trees of claims, creating quantum resistant dithium signatures, managing the smart contracts used for anchoring the base and establishing a decentralized oracle of death uh all while maintaining GDPR compliance. So the first step here is actually creating that will. So our interface lets estates define a set of inheritance claims which we put into a Merkel tree and this lets inheritors verify that their individual claims are part of a will without revealing the whole thing.

Now we anchor the roots of those trees to base to establish immutability guarantees and then we used quantum resistant dithium signatures to prevent spoofing even in a quantum computing world. Next we need to validate death. So, traditionally, inheritance is managed by a centralized party like a lawyer who declares when I'm dead and gives away my assets. Instead, we name witness wallets to act as a decentralized oracle of death. They add their signatures to another smart contract on base and consensus that I'm dead unlocks the will.

And the last piece is actually collecting inheritance. So, inheritors make calls to the weave chain node to see claims associated with their wallets. And our patterns mean that everything is still GDPR compliant. Now, there's only three of us because we killed our fourth teammate for testing purposes. Uh, so here you should be able to go and see.

Yep, this is his inheritance with his claims and witnesses. And I was happy to declare that he was dead. And then uh Zealer over here was able to go and pull down uh his claims as well as verify that they were part of the tree. So for next steps, we are already working to be the infrastructure for Aarifi to do this because there is more to a business than just infrastructure. We want triggered uh release mechanisms for crypto assets upon death.

Though we designed our system to work for any asset, crypto or non-crypto. We also wanted to enable uh percentagebased claims. A notification engine would have been sweet. Uh and finally, Paul made a beautiful comprehensive UI prototype uh that fell victim to the hackathon horse. Thanks, Eat Denver Rocks, Bass Rocks, Weave Chain Rocks, and we're thrilled to be here.

So, wait, do I want my my people to know what they're getting? Like, so this is the point of unlocking the will. Only at that moment where I'm dead can somebody actually understand what their part of the will was. Oh, okay. They only just know that they have a claim.

That's right. Okay, got it. And why did you choose the witnesses over like the typical dead man switch? You don't like dead man switch? Yeah, I think Bequest Finance is doing the dead man switch, but it's kind of annoying.

Like I want to go and set my estate and forget it, not have to go and log in every 365 days to say I'm alive. Granted, you know, this is sort of like is consensus actually a good thing. There is a chance of collusion that my witnesses would cheat and try to steal my assets while I'm alive, but choose smart witnesses. Indeed. Awesome.

Thank you. Thank you to everyone in the infrastructure track. All right, unfortunately we did not find the last of the infrastructure teams. So we're going to move on now to the NFT gaming and metaverse track. So up first we have Bersark, then we have my Mule, and then we'll move from there.

Middle. Oh, this one. Okay. All right. Hey, we have Bak.

It's bazar but zk. So bazark right. So simple pitch. You can own NFTts which have zk attributes. So you can reveal some attributes and you can keep the rest of it hidden.

You can use this in game engines and it we have built a marketplace which the game engine can update as you play the game and you can prove that these properties are in fact correct using zero knowledge proofs and the game engine can obviously update them as you play the game. So imagine something like Fortnite with but with decentralized ownership and you own the characters and the properties and it is crypto crypto cryptographically verifiable. Yeah. So he will expl do the demo. All right everyone uh if this works cool okay so uh this is the marketplace that we explained essentially uh if this works.

Okay cool. So these are a bunch of NFDs that I minted. So as you can see um each of these NFTs have certain attributes, right? You got speed, endurance, armor because those are the only ones I could remember. Um so now you've played all these games.

You want to sell your character because someone offered you an insane amount of money. Sure, why not? So now what you can do is that person can be confident that when they buy your character they have a proof that your character speed is above a certain value like three or four or five out of 10 but the other values are um hidden. So, you know, you might you might be a a character farmer where you just play the game 24/7 and get all the values, but it also enables people like, you know, you had a great character, now you're done with the game, sell some sell it, get some money and get some utility as well out of it. So, what this does is when you click the tick mark button there, what it does is those zero knowledge proofs are available on the marketplace.

So you take that proof submit it on chain to make sure that the values that are displayed are the same as what the prover is saying. So that way you are sure that yes if I buy this the values are hidden even if even after I buy this and also the values are the same and you can see it the game engine can see it but nobody else can see it and this is where rollups also come into place because when Okay cool uh yeah so I guess for the last 30 seconds I don't fully understand the exact use case. Can you go a little deeper? Like why would someone not want to show all their character attributes if they're selling it? Sure.

Like um if you take the recent trends in fog of war games, right? So you have um all these game characters that you have like special guns u attributes of like skins etc. Now you um anyone like in most games you can go up to a character and view everything but you have worked hard and you don't want to show this to anyone but you want to enter PvP battles and say like oh you know what I beat you and I don't want to show you anything but you can go look online if you want to. I'm not cheating but I have proof of it on chain and rollups can prove that to you after eat block after block after block. And with our marketplace you can prove that yes my value is above yours and it's I don't want to tell you how much it is but it's above yours.

The other use case also is with um property ownership in the metverse and marketplace, right? Attributes don't have to be just games. You can put Okay. Any Thank you so much. This is a really cool project.

Nice use of ZK's. Well done. All right. Up next, we have my mule. And while we're waiting, if you are part of the DeFi track by the project name of Gastley, please make your way over to the stage left to meet Derek.

Again, this right now is my mule. [Applause] I mean, hi everyone. Oh my god, what an audience. I'm so happy to be here. So um that's our project called my mule is an onchain um 3D Pokemon um slash samagotchi game with extended utility.

Um well I love I mean it's cute. I mean adorable. I love it so much. Um so if you wonder what gamey is, that's this. And let me explain why what that does really mean.

Um, so basically, um, the game play is following. That's just the level one. You buy this adorable NFT called Mule. So that's your hopefully forever friend that lives on blockchain and NFT essentially. Um, like every responsible pet owner, you have to take care of it.

So it means pet it every single day, feed it, and play with it. Duh. Um and if your mule is happy it uh meaning um the level of happiness is above 51%. So this little cloud is an indicator. Um it generates an in-game currency um called mu.

So that's pretty exciting thing. NFC able to generate token right. All right. So um but um the point is if your mule is unhappy so basically happiness goes to zero it dies so it really disappears. So let's my um co-founder explain the tech set.

Um so let's talk about how this is built. This is built using a custom smart contract which is a ERC 721. And in the smart contract, we store um this GB file, which is a 3D model on the right, and this behavior graph on the left, which is an interoperable format for defining uh game behavior. And the the unique thing that we do here is we actually link this behavior graph to um the smart contract that this NFT is minted on. So we're able to um pull from any um smart contract function state and render it real in real time and apply it to the 3D model.

And additionally uh we can have actions that you do in the game um uh fire smart contract transactions. And this interoperable format is currently in discussion and going to be um supported by most major game engines and Meta and Microsoft and and Amazon. So um works. Yeah, we're excited. Uh the the all the files are stored in IPFS and um the application is entirely serverless and hosted on IPFS as well.

We Okay, that's it. That's awesome. Awesome. You're hosting it on IPFS. Um I'm also curious.

I noticed you were accepting a lot of MetaMask transactions kind of throughout the course of I think trying to make your mule happier. Um, I'm curious what you think you could do there that might be able to smooth the experience. Um, for a user who might not want to go into MetaMask every time they want to do one of those kind of engagement transactions with their with their MUI. How could you make it better? Um, well, I don't understand ex entirely how a can abstraction works, but I imagine that you could like bash transactions together or you could have someone sign a bunch of transactions and someone else could execute them.

And also typically you wouldn't be doing this like multiple times in a minute. We just shortened the game duration to be like 30 seconds. This would be something you would maybe coming to do like every once a day or something. Gosh, that makes great sense. Thank you guys so much for the presentation.

It's super cool. Alrighty, up next we have Sinastthesia. This will be the last presentation of the NFT gaming and metaverse. [Applause] Check. Check.

All right. Hello everyone. We are Sesthesia and we are here to sorry. Okay. We are Senesthesia and we're here to reimagine your NFT collection.

So, we've noticed some opportunities particularly in the music NFT space. Uh mainly, you know, the collecting experience isn't that exciting. You're minting, maybe you tweet about it, maybe you get access to a Discord. Um but we believe that can be um a richer and more engaging experience. Um on top of that, you don't really have the ability to showcase these music NFTts.

A lot of times it's a album artwork or a single artwork. We haven't really diverted too much from that format. Um and lastly, we believe that um you're not really getting to the the heart of the blockchain technology just through audio NFTTS. Um so with that, we have developed a solution um through generative art actually. And so our platform is a generative art platform utilizing music NFT metadata to actually influence the visual output.

So what this does is this incentivizes fans to not only continue collecting their music NFTs but also hold their NFTts uh with the knowledge that this activity will actually influence the visual output of your generative art and actually bring them closer to a more blockchain native experience. Uh and for the artist, this actually helps diversify your release strategy by incorporating um some additional elements to the NFT out outside of just audio. And and in this uh in this way is also enhancing your marketing strategy by having this kind of rich visual component and all the while deepening the relationship between the fan and the artist which is something that uh we value very greatly. So this is essentially your Spotify wrapped for your onchain collection. And as you can see here your top artists, your top songs, your minutes listened, your top genre.

essentially all this data being fed into a generative art algorithm to give you a uniquely verifiably one of one piece of generative art. So what we plan to do is with our Genesis drop on board the top three music NFT communities in Sound Catalog and Zora totaling approximately 15,000 unique wallets. We'd love to get into some artist curated drops where you can really get granular on the metadata. And then lastly, integrate with Spotify who's got 500 million total users. And this is how the process would work.

Run it from the front from the top. All right, that's it. All right. Thank you. So, I have a question.

How do you how do you imagine the end consumer like uh interacting with these NFTs once once they've done all this? Is it is it going to be like a like a new kind of Spotify repository or is it like like how does that how does that deepen my relationship with the music? So, it's very much tied to the narrative as well, you know, understanding that you are actually helping create the output by your fandom essentially. And then of course obviously uh with Spotify wrapped it's such a viral experience. People want to share that stuff and this just adds another kind of visual component really tying the emotion to uh the creation experience.

Cool. I love it. Thank you. All right. So that wraps up our NFT gaming and metaverse tracks.

Up next we're going to jump into DeFi. First we have ZK PO X. Then we have Tribe Credit. Then we'll have Gastley. And just last but not least, if you are part of Dows and community and you are member, please go see Derek.

All right, this is ZK PO EX. [Applause] Hey, what's going on, guys? Um, first of all, we're honored to have gotten the first place of the DeFi track. Uh, one of our teammates, Fed, couldn't have made it. He had to catch a flight early.

Fede, we love you. You're a rock star. Uh, today we'll be presenting ZK POEX, which is essentially zero knowledge proof of exploit. So CK POEX, it's um is a tool that allows white hackers to report live vulnerabilities in smart contracts without actually revealing the exploit itself. Oops, sorry.

Essentially, there's two issues with current bug bounty programs. Uh first of all, teams are inundated with bug reports and a lot of it ends up being spam. So a lot of the exploits that are vulnerable get essentially mismarked as not vulnerable. This is actually what happened with the wormhole hack. Another problem that we have in bug bounties is that the white hat hackers might not get paid even if they disclose or they might get paid partially.

So in terms of architecture, what we did is run the Sputnik VM which is a ROSS implementation of the EVM uh inside the risk zero uh CKVM. This allows us to compute and prove any computation inside an EVM environment. As you can see, we have private inputs and public inputs and this generates a proof that can be verified by the project to ensure that the hack or that the exploit is actually um true. Okay. So this can be generalized to all types of exploits is this is exploit agnostic.

We have proven re-entrance case for PC. Uh but this can be used to prove any change of state in an EVM environment basically. So again, essentially we can copy any live state of a contract on any EVM chain, whether that's Ethereum layer 1 or scroll or Binance chain or whatever it is, and we can submit that state onto risk zero and then prove the exploit trustlessly. For future improvements, we're planning to do a CLI tool to simplify the process for auditors to easily fetch the data uh storage and address of the contract. And we can also scale it using the bonsai network to verify the proof.

Um in the future we also uh early on we will work with an escrow committee. Uh and in the future we can fully trustless uh have an onchain approach to um submitting the bounty and claiming the bounty basically. Uh also like what's important of this is like okay thanks guys. Uh thanks guys. um really awesome and creative use of um and then the first time I've seen anyone using the the bonsai tech stack.

So that's really cool and also um really timely as all the most of the ZKBM projects are moving towards auditing. Um I have a I have a question about the the business model like what how does this um how do you imagine this kind of working in terms of in that side? I'm sorry business model for making profit or what do you mean? Um I think I misunderstood the the question on that. Yeah.

Business model for for making the project sustainable. Uh so the the first goal of this is to really just make DeFi safer. That's the thing that we really care about the most is we're in the wild wild west of finance right now. And as a programmer there's always bugs, right? So the first step is to just to make reporting vulnerabilities more incentivized so that people don't hack projects and that we can actually make sure to patch these issues in a responsible way.

Um from a business point of view of course you could take a small percentage of the bug uh bounty claim which I believe would uh provide value to the projects themselves. Yeah. Awesome. Thank you. [Applause] All right.

Oh, man. Up next, we have Tribe Credit. Hey, Denver. How's it going? Uh, welcome to Tribe.

credit. Tri, what is Tribe.credit? Tribe.credit is a peer-to-peer lending protocol that empowers anyone and everyone, I mean everyone, to provide or receive credit.

The current state of credit. This looks very familiar. It's very web two, very top down. The issue with the current state of credit is that many people don't have access to it. And second of all, it's limited to its top- down centralized party and top down structure.

Meet Tribe.Credit. We're we use existing social networks and web3 ethos um of autonomy, self-custody, and bottom-up economics to facilitate credit and lending in a revolutionary way. I'll pass you on to Mendele. He's the man who made DeFi accessible for everyone with his stuff.

I paid him to say that. All right. Okay. So, here we're just going to hop right into the UI because we're hoping that's going to be self-explanatory. One of the things that we focused on in this in this application was that it be a web 2 experience.

This should be like downloading a regular app and that it shouldn't be anything confusing or anything that would make somebody feel uncomfortable or not confident that they know what they're doing. The system just relies on you entering a phone number, clicking sign in, and over here we're having what's happening in the background is that there's a smart contract wallet, and we're going to be creating two signatures. The first is the phone number, and the second is the actual the phone itself, which is going to be a hardware wallet. Those two signatures are masters and can confirm transactions. And right off the bat, after I enter my phone number, I somehow have available credit.

Now, the question is, how? Who is lending me this money? Tribe users add money into the system, then go through their contacts to choose how much they trust each person with. Now, who sees when I borrow? Well, nobody sees when you borrow.

Lenders only know that somebody that they trusted is borrowing from them. What happens if I don't pay back? Well, after repeated warnings, it will be revealed to your lenders, which includes f friends and family, that you owe them money. You may also be added to the systems blacklist. If you use the lending pools themselves, those funds may be used to to pay back lenders.

And now we're going to have just a quick graph to show what that looks like. Abe deposited $100 and Lisa deposited $100. John and they both trust John each with $100. So John's pulled credit is 200. And now you're also going to be able to have Yumo, which is our partner, also be able to provide credit to our users.

And anytime somebody borrows, it distributes it amongst the people that they're borrowing it from. And they don't know that you're borrowing it. And they don't know and you don't know who you're borrowing from. And if so, this is a cool hack. Uh I'm curious how you plan to bootstrap the network of all the people that have this going on and also two questions and one like aren't you worried about getting sim swapped and whatnot?

Sorry I can't hear you. Sim swapped. Sim swap. Oh, so that's an excellent question. So one of the the SIM swap problem is is a legit problem, but the the way we're having it set up is that basically when somebody authorizes a user to be able to borrow from them, it it's essentially a limited time approval.

Um, and also you have to be in each other's contacts for the credit to apply. So, we're using a a few uh other factors to ensure that that that credit won't be able to just be used by anybody. And if a certain if certain parameters are not met, you have to be confirmed again by the person who's giving you the the permission. Yeah. Oh.

Oh. Oh, I thought Okay. Um, uh, yeah. So basically the essentially when a user signs up there's benefits to somebody who's lending and therefore there they have incentive to share with their friends like hey download this app I gave you credit and I'm not going to know when you borrow but there's benefits to me if you ever do all right up next is Gastley and then we'll move shortly into Dows and community. Awesome.

Um, hey everyone. Uh, we are team Gastly from India and uh, thanks for having us here today. So, Gastly is a simple Chrome extension that lets you pay your gas fees in any token of your choice while using your favorite dabs. I mean you could be using unis swap, openc, cow swap, whatever, right? If you have our extension installed, you start getting an option to pay the gas vision in any token of your choice, right?

And I mean that's what the great part is, right? Uh you don't even have to move to a new product and still have a much better experience of using the existing products, right? Um we are live live on Polygon mainet and we are going to demo you uh this live on unis swap. So here you have the from token you can select let's say USDT or uh so you start getting the option for USDT right uh or MATIC or whatever you want to select right so let's say we select USDT and we uh click on swap so this transaction is actually happening in real time uh we sign the transaction And that's it. Uh we can even see the transaction being there on polygon scan.

Uh in a while maybe uh we can reload it. But yeah, anyway uh so this is what the uh uh this is what Gashley is, right? And uh as I mentioned before, you can also select different tokens. Uh if you select let's say die, you get an option to pay and die as well. Uh one of the interesting parts is that uh while we were building this, we also shared it with our community members that we had and we already have around 800 odd users already using it and with a lot of great reviews as well.

So that's something great uh I mean uh pretty interesting for us to be honest. So yeah, pretty much this is Gastly. If you guys also want to use it, uh please, this is our uh QR code that you can scan and uh uh join the wait list and we should be having some uh airdrops as well soon. Uh just in case you want to use it out. Thank you so much.

[Applause] Wow. Yeah. No, this makes me wish I thought of this earlier. Um a really amazing idea. I I have a question.

What what's been like the biggest challenge building this and and why do you think no one has done it before? It seems like a very obvious gap in the Sure. Absolutely. I think uh the biggest catch here is that the process of getting the approval to deduct the token from your wallet is not really straightforward in all the chains. For example, the reason why we could do this in Polygon uh very straightforward immediately was Polygon has this execute metatransaction function as well as permit functions.

What it does is that it gives any smart contract the ability to deduct tokens from your wallet without the gas. Right? So anything everything that you saw was completed without us having matic in our wallet. Right? So uh now to be able to do this on Ethereum we need to use the EIP2612 which is a bit far away right or you have to hack our hack your way around which is something that of course nobody has tried it uh yet and we are working on it.

Um I mean look honestly uh innovation takes uh hard work and effort to build right. So uh that's where we are. So in fact while we have made it live on unis swap we we can also show you the uh prototype for cow swap. So this is how it's going to look on cow swap right and we are doing this for openc on ethereum as well pretty soon. Um so yeah I I I hope that uh answers the question.

Just really quick can you go back to the I would love to see what it looks like on polycan. Poly what? sorry on polycan like the block explorer cuz it didn't quite load and I just love to see it. Yeah, this is what it is. So you can see the transaction is a success.

Um even the tokens transferred you can see these are uh the contracts that we uh executed. It's very cool. Well done guys. Thank you so much. Um also a quick shout out to our team uh sitting back in India who has been helping us out with this as well.

They couldn't make it here but uh you guys are rock stars. Thank you so much. All right. Okay. We're now going to move on to Dows and Community.

Um this is our last track, our last three and then from there the judges are going to go back and they're going to end up picking their top five picks. So first up we have denoted. Then we have member and then we have gov blocks. So denoted [Applause] Okay. Hello.

Uh we're team denoted and for this hackathon we asked the question how do we fetch and visualize blockchain data best? So if you look at the space today, we have many prevalent actors such as Dune, Coalent, Subgraph, and many more. All fantastic products that can use data from the blockchain space. But imagine writing a newsletter to DAO, a monthly letter to your shareholders, or just a blog post with the latest blockchain um stats. We would need customuilt solutions or at least consult multiple data sources to gather the information we want.

So what's the solution? We built denoted. It's an open-source knowledge management editor that easily integrates data from the blockchain by leveraging these powerful APIs directly into your editor in one single space. Let me show you. So the idea is simple.

You start by signing in with your wallet and then you just click create and then you're off to writing and editing whatever you want. A blog post, a newsletter, a white paper and so on. Whenever you want to fetch some blockchain data, you simply make a slash and you can get the data. The noted is open and composable so that each community or team could use the noted in accordance with their needs. Our vision is for creators to utilize our tool to share web 3 insights with the rest of the community visualized in the way that fits you and that would be our small contribution to bringing in the next billion users.

Thank you. Wow, this is incredible. And it looks like we have uh some some extra time. So, h are you guys planning on adding this into medium or or uh some other what's the web 3 version mirror uh to make this accessible to anybody? I mean, it's just incredible to have a blog post that's always updating with onchain data.

Do you do you plan on any integrations? We did talk about it. Um I think it's very early. We have talked about some uh horizontal next steps. for example, adding more integrations, more functionalities.

It's still very much an MVP. Um, we also talked about, you know, the vertical next steps if we would add some permission based workspaces, for example, some, um, token gated, um, um, spaces, for example. Um, so we're still in the talks with it. And really quick, uh, what's a sustainability model? How do you guys make money using this or building this?

Yeah, we haven't really gotten that far, but I mean just a simple subscription uh with stuff is pretty good, I think. Oh, cool. Subscription model. That's fantastic. Well done.

That's really beautiful product. Thank you guys. [Applause] All right. All right. Up next, we have member I'll take you back.

Okay. Hello guys. Uh thanks for spending time listening to us today. Uh we are building member. We are delivering standardized membership with expiry model built through ENS name wrapper.

So the team I'm Julie Shu and this is Harry and we have two other members but they need to go back and take their college exam. So they're not here but they are wonderful and we are all from OR3 and ORS3 is an ENS endorsed uh project that we want to push the boundary of more ENS name and subname use case. So here's the problem we uh there's two downside of NFT or token membership. versus is that by nature it's one-time payment. And with that being said, the uh entry the barrier of entry is very high because you know here the firm's benefits cost about $4,000 a year ago and even more expensive back then it's about 10k and the other is that the core team or the community lead are not incentivized in long term to deliver consistent value to the members because they make most of the revenue at the beginning of the initial sales.

So what about we build a membership with expiration? That is not a new thing, right? That's is not hard to think. But let's put it this way. How do we build an interoperable and composable solution?

That's the hard one. And I believe ENS name wrapper is the right solution. ENS has 2.6 million name registered and has a lot of dab that already have their infrastructures. So that's good.

Good to start. And the other is that it has expiry on chain. So with that being said, we built our platform. The admin and the users can have all the features and we build a standardized API for some gated access control. I'm going to show you a real quick demo.

This is something I've been testing out for 31 uh for uh the last week and it has 31 membership claim. But I'm going to do this um because it is new. I'm I'm going to do a new membership job. Uh I know Alicia, you are here the lead of um of ENS uh governance of ENS and I'm going to drop you the first membership here and people can also mint And with that being said, I can change a wallet. I can mean another subname because we don't have time.

I'm just probably go to my plans. And the upside of name wrapper is it says ERC 1155 and that means we can resell it. Thank you. [Applause] So ENS is live on mainet. It's kind of an expensive place to be doing this for memberships.

Do do you have a plan for how you deal with gas costs or scaling issues? Yes. So there are different way of approach that. First is using L2 like optimism as a solution and the other one is we can use uh ENS actually supports DNS and the vision is actually have the DNS to be 80% of the ENS ecosystem in the future. So with DNS that the cost will be way lower and we also have B create um in our platform.

So so that anyone uh can benefit from the B creation because we save gas fee too. And with that said, feel free to sign up for that and we're going to both create all the subname for you guys. Just check out that QR code. L incredible work. That's amazing.

Well done. Thank you. Thank you. We don't really sleep in the last weeks. Thank you so much.

Beautiful project. All right. Here we go. This is the last one. This is Govlocks.

We are. and then we'll we'll move to the final final final part. All right, give it up for Govlocks. [Applause] This work to goss. My name is Eric.

This is Barav and Evan. Special shout out to Oz who's at home right now. He got violently ill and wasn't able to make it. We help communities govern better so they can build more. I spoke with over a 100 DAO thought leaders and they shared with me their pain points including low participation and depleting treasuries.

But one pain point stood out above the rest. Dows get stuck with incomplete or overly cumbersome governance models. And when the governance models break, so do the Dows. Communities need a governance model that can evolve as the community evolves too. And GovBlocks achieves this through infinitely scalable diamond smart contracts.

Participation modules can amplify or decrease uh the the weight of a vote based on good or bad voter behavior. Consequence modules can punish community members who violate community rules. There's an infinite amount of modules that can be created such as Ziki identity, reputational badging, memberships, harbinger taxes, and much more. Govlocks integrates with your existing domain, so your community never has to leave your native website in order to access proposals, voting, or the marketplace. Govlocks addresses the very large 200 billion or roughly marketplace for for Dows and NFTts and we take a slice of the action.

In the past six days, we've hacked about 70% of the core features of our top competitor which took them about seven years to do. We're really grateful to be here at ETH Denver. Uh thanks for for being here. We'll go and do a little live demo now. Uh so this is a sample DAO that we launched on three different chains.

We launched it on Binance, on base and on polygon. And you can see here you have a bunch of options. This is the governance settings for the DAO. Now after the DAO is deployed, anyone can propose a change and when they propose the change, it creates a proposal and if the proposal receives majority vote before the vote deadline ends, then the uh the changes are in effect brought into the smart contract. You can in this case, let's say that you wanted to experiment with a participated awaited voting participation module.

You could track how often community members participate and if they continuously votes over and over and over, you can give them extra weight on their token. If you have one token and you have a extra weight factor of three, your one token could count as three votes. And this is just one of the many modules that we can add um pretty much at any time. So, um, yeah, this GovBlocks is a fully decentralized Dowo management platform and we're just really grateful to be here. So, thank you very much.

So, very cool. Uh, one thing, there has been at least one govlocks in the past. Um, so that that name may be a hackathon name. Um, but uh like I'm I'm curious how modular it is. Like I mean I I feel like given how like the things that you showed so far it's um you know like you you have some frustrations with with voting in the past um like you know how how flexible can can you get it like with with modules and whatnot?

Yeah, great question. So the the specialty of the diamond contracts is that um think about it diamonds as as you know there's a main contract and behind it there's bunch of subcontracts and you can add infinite amount of subcontracts. So there's infinite poss amount of logic that's possible to add to it. Uh so virtually there's no limit. Now uh typical smart contracts they have a storage limit you know you have a contract slice limit.

All of that doesn't apply to uh to uh the diamond contracts and so that way the Dows can evolve uh and keep adding logic as they go uh and as they're evolving. Cool. Thank you. [Applause] All right, that wraps up our top 18. Actually, top 17 because we we missed one one team.

So, here's what's going to happen next. The judges are going to go and they're going to go backstage. They're going to deliberate for about 10 to 15 minutes. They're going to come back in about 10 to 15 minutes and they're going to present their top pick out of the top 17. Um, and so if you guys would be more than happy to stand up, you can go back to the green room.

uh Derek, our amazing community steward. He's going to come up on stage, talk a little bit about Camp Biddle, talk about community, um and then uh we might have a special appearance by a guest. So, well, the judges have finished deliberating. They have picked their top five. So, here's how the rest of the evening is going to go.

We're going to bring the top five judges. They're going to present who their favorite uh project is. We have enough time so that way our photographers can get a photo with their judge with the pick and then from there. Look at that. We love developer doer for sponsoring.

There we go. So, sorry guys. All right. So, if we could bring back the celebrity judges and then we'll finish this up and then uh we'll go from there. So, please welcome the judges.

Buffy, you're more than welcome to stay. All right. GMGM, of course. Well, if I get to be the voice, let me tell you that was really hard. These projects were incredible.

This was the best. Spicy. Yeah, it was it was spicy back there. We had some fierce debates. We had to go back into the the build box and figure out were these did could they really do that?

And it was incredible. What Can we get a round of applause for everyone who was up here cuz it was amazing. I I've judged a lot of these and I've never seen so many applications that were so so great. Uh so uh for me the the the choice my choice it was really tough but I have to give it to fund public goods fund PG. It's beautiful, simple, and honestly, we've wanted to do it on Giveth forever.

So, like, go talk to Mitch. He's trying to build this. Uh, so thank you so much. And I'm cheating. And I want to give a special shout out to Denoted.

Honorable mention. Great product. Awesome. I think uh teams, as you're called, you're supposed to come up here and take a picture with your uh your judge who has picked you as number one. So fun PG, come up on stage and take a picture.

They're coming. Hey. Hey. [Music] Bring it in. Let's fun public.

It takes community. It takes the universe. Let's do this together. [Music] [Applause] Thank you so much. Thank you.

Thank you. I appreciate you all. Thank you. Awesome. On my angle, um, I have to give it up for Swappy.

You guys built something beautiful, easy to use. I can really see the applications bringing this into kind of like, you know, messaging with folks. You know, someday we're going to integrate this in with like all of the different assistant technologies. So, really give it up for Swappy. Guys, come up on stage.

Would love to take a photo with you. [Applause] So, um, this is probably the hardest decision I've had to make in quite some time and multiple times other judges held me back from picking one team over another. But it's simply because everyone is just so great and it's fantastic to see so many excellent projects being built here. So um my top choice is um ZK PO X. So, I picked ZK POEX because that's the one that I think I'm most likely going to use and look into after this hackathon.

So, it's super biased, but you know, well done, guys. And I want to give honorable mentions to Bitcoin Satoshi Vision. I think that's a really interesting project and well done guys, too. So, well done. [Music] Well done.

They were the first So, it was a condition of being up here. I really was trying to get it that I would have to wear the Buffacorn costume, but unfortunately they didn't let me. I thought it would be funny when I took it off and everybody was like expecting it to be Vitalic and instead you'd be dis disappointed with me. Um, so, uh, I'm tempted to pull an audible. Um, but, um, my choice is, uh, Bizarre K.

I thought like, look, zero knowledge is, uh, the future and it's a really cool little, uh, you know, application. So, congratulations, guys. Come on up. And my honorable mention was inheritable because wills are a real thing and I think they're super cool and it's uh, like a lot of people have done it, but like putting it into production is is awesome. So, I love that too, guys.

They don't want to take a picture with me. I understand. My wife doesn't either. Thank you so much for Yeah. [Applause] Okay.

Uh, last but not least, uh, I took a lot look at the design of of everyone's projects and there are a lot of really well-designed projects. So, my decision definitely was not easy. Uh, but I got to go with Sesame. Great looking product. Your your design fits your use case.

Instantly instantly usable by by any consumer today. So, so well done. Come on up. There they are. There they are.

Oh, cool. Yeah. Here. No, I can I can hold it. I can hold it.

[Applause] That's all right. How awesome were all those projects? And how awesome were our judges? All right. Well, that wraps up the Biddathon for 2023.

Do we have another mic for Derek? There we go. Cool. Is uh I don't know how to how to I don't want to close this out. A it's it's like after after six months of planning all this.

Jason and I trauma bonded getting ETH Denver ready for everyone. Uh so genuinely if you would like to show a little bit of gratitude for all of the folks been on site, the coffee folks, the volunteers, the sponsors at their booth, the venue staff, everyone that made Eat Denver possible. It would mean a lot to us. A little round of applause for all the folks behind the scenes, AV parking, all your Uber drivers. Truly, it takes a lot.

It's a free event. We really try to make it accessible for folks and we know there's bumps in the road along the way, but we appreciate y'all coming out and making us special. This was year six, year of the spork. And we got year of the spork whale next year. Year of the spork whale next year.

And I don't know if anyone caught John's one slide that was like, "Oh yeah, Ethur and Asia." Anyway, we'll talk about that later. Probably nothing. It's like, "All right, that's alpha, I guess." Yeah, Eth Prague.

And how awesome was Leah Lamar? A big shout out for Leah. Do I get a shirt? There's one left. One.

Oh, let's a Patriceio. Thank you for being a special member of the community everywhere you go. Shining love. If you love Patriceio, a big warm round of applause. POAP would not be what it is without him.

Nouns would not be what it is without him. We would not be what we are without Patricio. I love you. I I think in the in the celebration of like community, I'd be really interested to hear from our like judges as we kind of wrap up. What was like the biggest takeaway or the thing that you enjoyed the most about E Denver 2023?

It's always the hackathon for me. So many cool projects, so much innovation, so many people learning how to build these things and combine protocols and like, you know, I kind of like the bounties setup where it's like, well, yeah, try to combine like these four bounties together and see what you get. It's that interoperability and just the hacker vibe of everything. It's just I I live for it. It was beautiful.

For me, it's the people, man. Like, uh, I got to meet so many cool people. I got to hear so many cool stories. uh especially Tinder and Bumble stories. Uh so thank you again.

Um but very cool. Everyone's been so cool. Everyone's been so welcoming. Um this was my first one too. So uh so thanks for making me feel welcome.

For me it's always community connection like just getting real human touch points at so many different projects, finding those opportunities for builder teams to come together, find collaborators, make something amazing with each other. I feel like these in-person events are so wonderful after a chunk of time where we weren't able to get together in person and I just love the energy that forms in these kind of community gatherings. So, thank you so much for organizing it and putting it on. Um, this is my first time attending Eth, but I've just in awe of the organization and how many different side events there are. So, you know, the variety and the diversity and how the coke city comes together.

Every taxi driver knows about this. every restaurant owner knows about this and you know I think that's a fantastic city that and also a fantastic organizers that can make this happen. So thank you guys. Tens of thousands of people in in a bare market. This is what mass adoption looks like y'all.

Thank you all for being here and thank you all for being here. This has been ETH Denver 2023, but it's not quite over yet just because you saw all the amazing stuff in our Biddathon, which is as always the core of our community. We still have a little bit more. We get to unwind together. If you stick right here in this room for just a little bit, we're going to be having a happy hour with free food and beverage.

Little clap for the food and beverage team. They've been working really hard, especially Goodart Coffee. Love you all. And we're going to have not one, not two, not three, not four, but five different musical artists at least. I've had a hard time keeping track of them here for our closing party.

So, if you're excited for the rest of the evening and to stick around and deepen those connections with folks, give it up in advance for our musical artists. Uh, and then show of hands. Is anyone coming to the mountain retreat afterward? Just coming up to Breck. All right, see you all there.

Thank you again. This has been Eat Denver. [Applause] whatever.
