Top 10 Hackathon Projects│ETHDam 2024│Privacy and Security

[Music] the 10 teams and we need some kind of like drum roll some kind of let's do something nice nice okay 3 2 1 the first team will is ZK loyalty woo the second team Oasis guard [Applause] oh my God the third Team B blockchain of things quick reminder could the first two ZK loyalty and Oasis guard please get here as soon as possible um and please identify yourself to Sterling so we also know that you're here I don't see anyone moving and that really bothers me uh honestly it's up to you if you want to present as a team then so be it uh this is your guys's moment so yeah woo okay we're g to no no no we got it we got a we got more to get through team number four is whisper team number five is block loock team number six is coor M okay guys I don't see a lot of people moving like come on come on over here uh number am I lo counting wrong DK loyalty Oasis C blockchain of things whisper block lock coor M next up browser socket MPC I love is that your team I love the [ __ ] enthusiasm man do you have a pseudonym do you have a pseudonym a nickname you go by no Nick okay the no nickname guy be like the no nickname guy next one is stealth the lock woo I love how I love how at least for me I'm hearing about these names for the first time so I'm really loving the enthusiasm and we're just about to learn exactly what they all do next up is jpeg station I am wondering why JPEG and not PNG we'll see what we'll see and last but not least stealth keyto okay ZK loyalty where are you guys at let's get you hooked in are we set with the timer for the five minutes I I I guess it's okay I I I also see it from here we're going to do does everyone still remember what this means does yeah some guys remember okay so 30 seconds before the end of the pitch we're going to start going like this and then as soon as there's one clap ideally from I hope me so we don't get ahead of time is that's then the end of their five minutes and that's then when we're going to transition so first up we're ready with the deck your timer will be up there and ZK loyalty so yours okay welcome it's a bit of a surprise but here we are ZK loyalty and first of all we go to the use case so all of you know loyalty programs payback Starbucks has a big loyalty program and there are many reasons for why companies do that or Brands and one of the statistics is 65% of the company's Revenue is from the repeat business of existing customers and it's way more expensive to get new customers than to reward existing customers and this is an easy thing for big brands for um yeah the ones I mentioned before but uh small shops on the right side they're really struggling with this and why is it they don't have the crazy Network effects of these big Brands they have a problem of if the small shop for example in a 30,000 people town or whatever wants to do this they need to be gdpr compliant they need to be privacy preserving and yeah also they are losing H huge market shares to these big um internet companies then our solution is ZK loyalty it's a gdpr compliant Anonymous loyalty program that any small business can Implement to reward repeat customers and yeah actually we are using um zero knowledge technology the Sumer for private groups actually and by this we can actually realize the use case so what kind of requirements or specifications we had for the systems we made some user stories to actually get to the use case what do we want to achieve and from the different perspectives of the users so as a small shop owner I want to easily enroll customers into my loyalty loyalty program so that I can start building a loyal customer base without a complex setup as a customer I want to sign up for the Loyalty program without sharing personal details so that I can protect my privacy as a shop owner I want to give points to customers after each purchase so that I can encourage repeat business as a customer I want to be able to check my loyalty points through a secure method as a customer I want to redeem my loyalty points anonymously and as a data manager in a small shop I want the system to be compliant with gdpr so what's the tech uh some of for I mentioned already that we used and also first we wanted to use use Oasis for the secret storage but actually we went for Phoenix the fully homographic encryption evm where we can actually add the uh uh score and in the next iteration when another score is added to it we can uh add up the encrypted values so we can do mathematical operations on the encrypted values which is perfect for the use case we are still using Oasis for the random number number generator function as we uh have an onchain rle so I will like we have the first MVP at customer to user group we are scanning of QR code and then we have a bit of a vision that several different user groups could be grouped together so there we really have this use case of let's say 10 20 shops in a small town they get together and through grouping these um loyalty groups they can actually have the power against the uh big Brands and companies now I skip a bit and we go for the demo [Music] [Music] ohue I got no wifi great pict try the demo the demo what does it do yeah okay imagine it was in front of you right now so basically from a demo perspective We have basically two apps one custom app and one Enterprise app so you as a customer you can create your s for identity um to make it a little bit more easy we will generate an qur code for you inside the app uh there will be a commitment stored in that QR code and then you can just go to yeah here is it basically so that that was actually what I just mentioned the QR code stuff from the customer perspective now we have the business the business also connecting to another application um and now uh the business can create the samper for group so it can also create multiple groups for different for example loyalty levels and here you can see the group ID and now the business will actually scan the QR code uh from the customer so we can see it here so that's the customer now we got the commitment ID and we will add the user to our loyalty group from the business perspective and in a few seconds we will see that we are ated and now the customer again can go inside his or her app and prove that the membership is [Applause] verified thank you thank you very much um please give it up for our first hackathon team woo thank you okay thank you you can go back down that way whichever way you want uh really um so yeah there was a lot of messages going fast we are missing some teams so if you're on the list um maybe uh yeah if someone tells you to be somewhere please uh do so um did you guys like that first pitch was it cool yeah um and I think for the people that are presenting I think the big takeway there was have an offline uh if you're going to do a video try and make it not dependent on Wi-Fi or set up a hotspot uh ahead of time unfortunately I think maybe it might be to do with the fact that we have everyone in the same room TBD um cool well second up we have uh Oasis gods did you guys have fun at the hackathon did you enjoy it no yeah you were the 2% guy I'm looking for you I'm looking for you cool well um your five minutes starts now y first of all hey everyone and we are coming from it blockchain actually and it blockchain is the first and biggest university blockchain uh community in turkey and that's the intro today we are with OS card and Os card is onchain password manager and we are providing a hardw hardware level security with pass keys first thing first uh the problem nowadays we are using many uh passwords we have like tons of secret case private datas and all the confidential things and traditionally we are using like password managers to store all the data but we thought like we should come up with like more uh like decentralized stuff and we should give the power to the user so with that user can uh do all the stuff they don't need any other like middleman and we come up with o card actually and you will see a lot of words but a bit later you will understand the all uh also guard the browser extension because we thought it should be really easy to use for the user so for example you are on your favorite Tex and you can just Implement your password from the r extension and you are good to go and uh we are uh securing the passwords on thanks to safar's confidential evm uh we are putting the all the confidential data to confidential smart contract and we are providing in the access via your unique Pass key uh so you can use your basically pass Keys you are using your biometric data uh for as a like private K and you are signing it and we use the R1 curve uh and we uh we verified the signatures on ois and we will see the we will show the all the demos so you will understand all the process in a minute so yeah hello everyone um so first of all I I will create a new account in the osis card uh you can download it from the Chrome by the way and use it uh we're currently in uh testet and the transactions will be a bit slow so I can start creating my account with my Biometrics so it creates a on the background um it creates a smart account for us to store the U passwords seed phrases and um private key Keys uh in um Sapphire test net uh why storing private Keys important because nowadays although account abstraction is quite popular uh aoas became also popular with the new eips and their usage will be continued so you have to somehow store your private keys but uh you don't want to use your papers or uh other password managers which are um centralized so I will start with creating my uh first password or I can use uh import feature which where you can uh import your um import your passwords from uh your previous password managers so I'm starting the import process by uploading a simple CSV file which you can export from the Google passwords or uh some other password managers um so we're waiting for the transactions to be approved so we are sending a biometric data to the oys network so it's verified using a p256 verifier um and it's uh different than the normal signatures that we Norm normally provide with our uh private keys and different wallets like metamask or stuff so as you see my passwords came here from GPT Z and and Docker I mocked my password so there's no any confidential information from me uh I can see my dat by pressing the I icon and sending my uh Biometrics again to verify that I have an access to this password so it gives you gives me the uh access to the password I can I have options to copy uh Delete and share this password with my friends or with my other accounts I can copy this because I I'm already revealed it I can hide it whenever I want uh and also I can manually add different stuff like I can add metamask private key here it can generate a secure password for you so um like you can uh when you don't know what to put your password uh you can use the random password generator and uh create your password for the favorite app so we're waiting for the um generation again so every time you have to prove that you are that person you have that pass key and uh yeah it came here when I want to reveal it I'm giving my biometric again and it's Sean [Applause] here super super cool who here uses a pulse word manager yay you're going to get hacked use last pass super cool thanks so much for that and thanks for coming from Turkey as well really appreciate it hope you had an amazing time okay uh we are still looking for some team so if you're in here like please uh move around uh blockchain of things whisper stealth lock jpeg station um next up I'd like to invite to the stage Block loock Please give it up for Block lock if you haven't if you haven't used the qf yet please do it um really it's it I think it's going to be open for the rest of today I believe um so today the day to do it um there are some chairs in the middle kind of around so if you are standing at the back you can kind of just come in here um even though there isn't that much space at this point but super cool that you're all here okay block lock you ready yeah yep yeah okay well your 5 minutes is now hi everyone thanks for having us it's our first hackathon we had a lot of fun um we we uh also did a password manager so um yeah there you go you'll be bored of hearing about password managers by the end of this um so our aim was really to um increase the user experience with using a password manager kind of like simulate using one or like Web Two like one password or last pass but with the benefits that you gain from a decentralized confidential chain like aasis uh so that was primarily our Focus um you can see our this is the team sorry I should have introduced ourselves but all of our beach photos at the Bott um so the problems that you can find with uh with like a web to sort of like one password implementation uh is you can have monthly subscriptions right which uh is like $3 a month which doesn't sound like much but it's $36 a year and then you know over a 30-year lifetime period is over $1,000 if you um use a pay as you go sort of um um way of of storing your passwords using a chain like a was it actually only costs just shy of a penny to store a password and each uh normally humans store around 70 to 100 passwords um so you know that's like a dollar so it's super super cheap um you also have the vulnerabilities that inherent to centralized Solutions as we've seen we've like last pass before losing over 30 million um uh customers uh passwords uh and on the other hand you have web 3 which is very complicated to understand and very difficult it's a high barrier of Entry someone like my uncle or you know Grandma would just look at it and be like oh my gosh no um so that's really what we tried to to do with this is to is to bring the ease of use of a web 2 solution but with all the amazing benefits that we get from from web 3 um so yeah like I mentioned uh we can have our cake and eat it too um it's cheap $1 for a lifetime use uh it's secure um and it's easy to use I'm going hand it over to my wonderful uh partner Jack not partner and he's going to show you a demo yes please Lord I hope this works okay so um yeah so we developed block loock as a Chrome extension um so what we can do is just run through like a flow if we go to a website like name cheep and just try to store a password so we can go to a signup process you fill in your details here uh block lock we use the content injection into the page to be able to uh Gest a password and then be able to store that onchain um so whilst we're waiting for that I should be able to just have to refresh apologies should request the I should there we go sorry delays delays in my heart just fell through the floor okay all good so yeah we wait for that so this has being stored like yeah St stored on chain um through through our contract and again yeah all secured on Sapphire on the secure evm so that is Sav so we can then go to our UI and again like Charlie said the main thing we were going for with this was for like ease of use and simplicity for you know users who aren't like accustomed to web 3 um so very simple you can retrieve your secrets from chain uh here's the secret that we just stored for name cheap we have basic functionality to be able to update a secret share it with a an ebased address and delete um the secret as well um so I think actually for for the demo that's kind of all I wanted to do I think we could probably just yeah we'll go we'll go and talk about kind of what our next steps would be obviously you run out of time for the for the hackathon but um some ideas that we had of where we would go with this that would be quite cool one that I I find pretty cool myself is um so I don't know if I presume you guys use like multiactor authentication tools like Google Authenticator or ory these are either like you know Hardware based uh MFA onetime password tools or centralized services like one password or last pass off for for password uh we had an idea with this where you know in future we could potentially Implement um kind of like MFA time based onetime password generation uh through the application for secret keys that are again stored on on chain on on Sapphire um that's kind of like our main one that we'd look to go for I don't know Charlie if you wanted to mention about any other future things you can see some things here Secrets Marketplace that was kind of a fun one we were like you know you could share secrets with people and they could pay for Secrets What secrets you would want to share with people they could pay for for is maybe a little bit questionable the use cases but um yeah let's show the let's show the video that VI did we got we got 15 seconds yeah 15 seconds Make It Count here you go just the the final thing work went into this yeah we got sound six seconds 6 seconds we got to go press play Press Play It's yeah there we [Applause] go got block block block block block loock cool thank you very much for that uh we'll see how many other kind of Pula generators we get uh I think it's a cool application okay coming up next is co corm co corm am I I'm probably reading it and not reading it how it's supposed to be said so I'm very interested to know how this said put your hands up if you've scan the qf QR code and signed up okay guys like the ones that didn't put their hand up please do the thing um it would be really appreciated I can't force you unfortunately um can't win them all can't win them all uh one thing while that's being set up it's so funny how the telegram group of the crew is kind of working where everyone's literally like triaging problems together the telegram messages are being formatted like right now I'm getting just one updated message that shows who's missing who we've got who's presented being reordered I love it so much so really great really great be like no name let's see okay we need a Time filler uh uh yeah [ __ ] it I have an air drop no y'all got any of them points no really really bad yeah raise hands okay photog yeah I like this I like this okay everyone say eam on 3 2 1 and raise your hands 321 e Dam that's what we like nice guys yeah thank thanks man cool you want to do it again yeah yeah okay this time we got on video not on Photo okay should we say something else what else can we say meme coins okay what do you want to shout e e right so there's a story behind this okay while these guys taking a while it's okay right so uh there's a person on the team it's Sterling she also writes copy and the name of this conference is called etham everyone know like e and turns out she made a typo one day and wrote eth fam and so we've been very much destined eth faming this up so on 3 2 1 we're going to shout eth fam because you are the eth fam this weekend 3 2 1 E fam woo I feel like I really like I should solidify myself in crypto history here you know like hotle midle like e funny who here was for the uh the L2 thing where we said that uh the ETFs are an L2 for Bitcoin yeah I know you were this was honestly this was one of my most favorite moments of the whole thing um so yeah let's see running out of ideas guys running out of ideas it is popping up but then it's turning off again so we'll see I would say for me one of my favorite moments was when my heart rate was probably unhealthily high during the debate between on the on the L1 scaling debate yeah that really it got me worked up and I was not participating it was a lot it was a lot that was that was that was cool though someone want to shout out their favorite moment from the conference biter bitter balla okay yeah a man who follows his heart his stomach anyone else magician was cool beer o' beer o'clock well that's coming at 6 o' so and it's going to be a long one cuz there's also the after party the Afterparty by the way starts at 700 and everyone can walk pretty much there together and it's quite nice uh but there will be beer afterwards and it's going to be well deserved after sitting through all of this content we know it's a lot so we appreciate team yeah okay let's do that browser socket MPC you're up let's go I trust that the tech guys will solve it and figure out what we're going to do but we're going to move on surprisingly enough there is a time schedule so we're going to try and keep to that block socket MPC he's coming he's wo sorry about that we make can it work on the fly a life man sorry just throws curve balls all the timebody Ry did browser socket MPC your time hasn't started yet relax we'll start thank you thank you yeah no do you want a hug you want a hug shall I do your slides and you said no okay we should do you want a hug sorry yeah no Oh e it's all good taking a look at your refresh rate it should appear on that screen I think like you guys have been much more stressed than we have like we've been stressed about making sure that you guys are chill but I know that you guys have also been stressed because it's a tight deadline so we appreciate the guys who come up here with still energy and make it happen it's a little bit emotional the E fam okay another fun experience from someone Joel I know you got a fun experience but we don't need to talk about that anyone else no one thing just give me one thing Knife Fight who saw the knife fight yeah we got hands we got hands a mean a mean had a knife fight with someone outside with plastic knives it wasn't a real knife fight but when I saw the telegram message I was like what that's that does not seem okay so the stealth the lock uh you should probably get ready in case we need you on stage so um it's not mirroring it it's uhing we knew that there would be technical stuffen in but um yeah we were lucky so far how do you not mirror you have a question what's the question my favorite defi application are you're asking really the worst person man it's really difficult honestly I'm just going to go with the simple answer and just say like Unis swop because I think it was one of the first and they have fees yeah but if you don't use the front end then there are no fees because uni I don't want to get into this this is too political any other questions this is a Roose okay can we just my preferred Dow I think the biggest one would be make AOW being like the most like true and currently decentralized however there is some there is something that's going on at the moment but I don't know enough about it so maybe my answer is out of date so okay uh I really don't want to answer questions about blockchain applications I'm not I this is so against my core values of giving individual answers I love blockchain and crypto and that's why I'm up here and I do not give preference this is no come on favorite meme coin favorite nft project okay if this isn't going to work we're going to go to the next one because we're really running out of time and um if you need to send presentations then okay stealth the lock stealth the lock we're going to try this I'm I'm trusting that something there's a lot of people stressed upstairs trying to figure out what we're going to do about this so um new cable I don't know man there's enough cables in this whole building so someone uh why does it come to answering favorite blockchain projects it's always like this you guys are just fiends and degens looking for the next Alpha come on okay p Market bed will the market bleed in the third evening of etham I think it's already bled to be honest so each evening well hopefully after this all these presentations it will go back up again so I think we might be ready with the next presentation is this going to work is stealth the lock ready woo okay we made it all right thank you stealth Al Lock with 5 minutes time starts now thank you everyone I'm Nick and here Coen and we'll build stealth aloc what's the problem that we are facing is that we try to solve how to connect web three creators with web three founders and how we do that we created a funding allocation strategy using Alo protocol integrated with Macy which stands for minimal anti-collusion infrastructure and also used waku for private messaging so people inside the pools can discuss about what they whatever they want in a private private matter so how it works everyone just connects their GitHub account and they can just import their projects easily so here we can see that all the packages that the project has the language it use the description everything that GitHub can provide us we can see the members and the feed provided by waku and also we can see the clubs we which are like the Dows here just some of them that we created and what Dow are doing is like again create a pools allocation pools and they have some metadata and how we do that connection like in the next steps we want to create something like representations like embeddings and do cosign similarity to notify projects which pools are going to deliver them money to continue building and thriving in the web ecosystem so here is a pool it's a a dow and all the pools here are dummy ones but yeah that's it and here we showcase the smart contracts which is the allocation QV strategy with the mai protocol integrated and here we have the deployment script setting the circuits and all the ma relevant stuff so yeah and we have some scripts to to see the workflow and here's a a use case diagram I would say like someone creates a pool the QV QV ma strategy which creates a Mac instance which creates a poll and recipient projects which are projects connected to the GitHub interact with the contract to register them pool managers can review them and the accepted projects can start get votes private private votes and then the coordinator of Mai can merge State process the messages create the pro the proofs and tally the results and then the pool managers can distribute to valid recipients what we use Ma is because of that we want to avoid bribing which is a really good thing because to have a democratic voting scheme so that's about Stealth alog thank you [Applause] everyone they still have they still have one hour they still have 1 minute and 30 seconds 1 hour so any questions let's go quick fire clusion specifically anti clusion because we're using the Macy protocol and sorry what if you're can give it I'm not familiar with yeah so the the you register first in the in the Merk Tre of the Mac contracts and then you can submit a vote that is encrypted with a different kind of key than the ethereum public key and you encrypt it with that and then only the coordinator has is a shared key with the coordinator has access to decrypt it so it's the it's the trust is based on the coordinator but the message the vote is encrypted with your public key so someone needs the private key to decrypt it yeah but doesn't that just make it Anonymous not necessarily an delusion it's it's just someone needs to the coordinator needs to generate a proof and that this proof is uh verified from the onchain verifier so that's how it is cool thank you so much thank you okay I just need to get the right chat up again or they know oh they know amazing I'm not sure which team it is though [ __ ] him we're trying it again we're trying it again okay everyone hold their breath okay let's get the slider up I really want we really hope that you're going to uh thing you guys are asking me about F my favorite project you could put in your favorite project let's do this together because I can't do it so if you want the guys if you really want the answer we're going to use the wisdom of the crowd the reason why I say that is every all Ellie knows this all the stuff that I work on I try and be as objective as possible and never give an opinion that's also why I love moderating so much because I just get to ask questions and learn from everyone but not Pitch anything so okay let's out let's see how degenerate this will get um I'm betting a 10 out of 10 so one can dream Brian no SLO okay what's clave could someone tell me what clave is no no okay are we trying a different project are we trying uh yeah backup all right we like that we like the backup whenever you're ready then okay you can come back to this you can keep on putting stuff in but let's start start the timer and switch the presentations and we should be off to the races with the name that I can't pronounce so really looking forward to it it's all yours just go just go it's fine okay okay so um welcome everyone to our presentation of cocon so uh we built an anonymous layer on top of coap so first um as a user you want to have three options like deposit Swap and withdrawal so first thing is then you want to deposit so you can deposit uh a certain token so it's anc20 here we have R is um you deposit it on um the public key uh given by the website it is uh the same on every Network it is plug and play on every EV evm chain uh then you need to generate a secret that will be shared uh with the trusted Computing uh Network which is oasis um and so by using the same secret several times with different addresses you can uh Mage the balances and so you can um hide uh the the the source of the funds way better it's not working okay so uh unfortunately the demo uh doesn't seem to be working because of Google meet but uh here oh okay yeah yeah it's it's happening so you generate the the secret then you need to deposit and then you sign the secret from your deposit key um with the secret and the transaction hash which will be verified on the trusting execution engine um then you can wait uh for whenever you want to initiate a swap swaps are intent based so they are M protected uh they are gasless and if the swap is unone you don't lose any anything actually um Inn can be aggregated uh so it provides more privacy um you can do it on any chain as you can see we can input the chain ID then for the withdrawal you can wait uh as well whenever you want to withdraw you don't need to do a swap you can withdraw where where uh whichever token you prefer and uh for the withdrawal you can add multiple wallet addresses you can add uh any amount you want so customized amount pair addresses customiz delay pair addresses so it means um you can uncorrelated completely the withdrawals um and then when you send the actual message uh as uh Oasis enables it's always encrypted so no one knows um everything you're doing and the best is even if they are is Dro I sorry if dropping your connection with Oasis they won't know that it's you who is withdrawing because of the different delays uh customized uh delays you can add um so yeah that's pretty much it uh for the user flow uh then we can go uh on the rmy uh with more advanced explaining so I hope you can see something um so you can see that the user gets the public address from Oasis the user uh Depo send funds then they prove the deposit and with the transaction High the signature and uh the secret Oasis receives everything uh verifies the signature verifies that the transaction happened with grpc uh we assume that drpc is trusted because it's a decentralized RPC uh then once everything is verified uh it is added to the database uh for the swap part um it's pretty much the same but the user doesn't have to sign anything nor deposit any fund nor use any gas um so yeah sorry we waiting we are waiting for the connection um yeah so yeah pretty much uh you signed an inant message with token in token out chain ID amount out and amount in um and you add the secret so osis can verify that it's you the origination the the right um owner of the tokens then you can verify then ois verifies the signature verifies the current balance uh batch everything it creates the intent solvers can fulfill the orders uh and permissionless Bot uh can uh update the state um by verifying all the orders for the withdrawal it's the same uh the sgx waits for the block to be [Applause] passed thank you thank you very much please give it up for cocum hey it does okay it has a ring to it go go go go go deal uh browser socket MPC I believe is next to you guys ready perfect that's yes okay let's try this again it's the hug dude hello hello woo yeah can we check the status of the poll I want to see really how degenerate it's got let's see how cheeky it it cheeky it is now cheeky cheeky all right okay this has changed portrait what's that is that a foraster thing what is it all right we getting started no when you're ready when I if you're ready then I am almost ready okay Synergy AI yd salana are there some salana guys in the room oh dear I'm surprised they weren't in the knife fight I did have a comp dinner last night where there almost was a knife fight when someone said salana versus ethereum it got pretty heated real quick real quick so are we good yes okay if we switch back um perfect okay well power socket MPC browser socket time is yours hey everybody my name is Ryan uh my project today is browser socket NPC uh and the reason this is important trying to navigate this is because we have these agencies [ __ ] blocking peer-to-peer from our web browser windows so Firefox gecko Google blink and apple webkit do not let windows open sockets uh and they're fighting amongst themselves which we've got no input in this us mere mortals to change web standards unless you try to convince them of things and they're not really responsive I've tried and so uh they've got common the these are the excuses they give for why we can't have nice things they they basically say these are examples of very dangerous things dangerous these were dangerous uh that generally we've concluded that no amount of notice and consent is sufficient to enable them safely so they're basically telling you that you're babies and you don't know how to use your computers and we're going to tell you what's right and so maybe they're right maybe they're not but what we wanted to do is make it so that cool applications like one of which is here TLS not that do multi-party Computing on sockets can do so from a browser window versus needing to be native or to use a web stocky proxy and so the way that we did that is through a there's a little there's a little bear TSN bear the way that we did that is through a experimental web API that Firefox is actually [ __ ] blocking directly um and so we I'm going to I'm just going to got a web pack going and then we're going to open it we're going to we're going to open it okay that opened it in okay so this new this new version of Chrome actually supports something called isolated web apps which allow you to open sockets and so this is actually a bundled web application uh locally signed by my own key I'm going to open it here you can see this just a web browser uh and it allows us to I'm going Peter Griffin my CSS there it is so I just opened up a window that actually open up a port on my local machine which allows that window which could be the piratebay.org it could be whatever site allows it to open a socket which is dangerous maybe but now this allows us to do really interesting things with multiparty compute and so what we have now is a demo where I can actually start a tlsn MPC proving session from a window and so I don't need to actually Bridge traffic through a a webify bridge which is adding more parties to the trust Assumption of this anti- collusion idea we have and so it's still not working but uh this was a demo to prove that we can do these things and to Showcase to these to our overlords Firefox Google and apple let's repeat that that we do want these things and so if you guys aren't vocal on these mailing lists I know you guys are in The ethereum Magicians ERC uh channels if you're not vocal in the the weird like web kit announced mailing lists like none of this stuff changes and no one's I don't see any crypto people in those mailing lists and so that's why I wanted to Showcase today what we could do uh and so yeah let's stop [ __ ] blocking peer-to-peer and let's free the web with multiparty compute thank you you actually have he has like 1 minute left so if there are any questions let's do quick round 5 4 3 2 Ma what are the mailing lists bro ask chbt or Google or something dude come on man come on sorry um yeah very much do I hope if you are interested in any of these projects or do have questions you can find them after this uh next up is whisper but it has a space between every letter so it's actually w h i s p e r aesthetic whisper aesthetic okay it's aesthetic whisper it that doesn't work I need an uh we have two more after this uh we still have not found jpeg station and just to fill you in on what's going to happen is uh we're then going to have the Bounty announcement so we the each of the partners is going to come up and they're going to very quickly share their Bounty which is going to be super cool and then Elanor The Mummy of East am is going to give a short closing statement and then we're going to go get drunk so just to like it's yeah I know that you're excited I know it will happen and it will feel absolutely glorious and everyone's going to have a great time just know it is in Dutch they say on the ve that only makes sense to Dutch people unfortunately okay guys whisper are you ready ready your timer is up there and it's how do we scroll down oh you might have to reset the timer they weren't ready he has a SCH oh okay 3 2 1 okay whisper we are whisper and during this hackathon we build a private linear quadratic cubic quartic and exponential cross chain public good funding a lot of password well well uh there are of course already quadratic funding platforms but there are some issues with them in most cases they are public and as we all know since we are here unchain traces between a donor and a project is often undesirable and also there is often no cross-chain compatibility in these platforms and also there's only the quadratic uh curve available [Music] y so we wanted to Def redefine quadratic funding we make it private we make it cross chain and also we make it more flexible we do this by having easy round creation and donation interface uh public round contribution with private project selection so if you select a project nobody can trace it back to you we have donations that are enabled from any evm network so you don't have to first bridge to the correct Network to make a donation and also customizable curve options okay so from our Tex stack we used to you know bootstrap the stuff we use scaffold for the front end and then we completely developed the contracts so we call it us the whisper contract and we developed the voting contract the part that you see here somewhere in the in the middle is all based on secret Network so secret Network provides us the Gateway contracts on the evm side as well as on a secret Network side and relaying so that's all handled by secret Network then on how the flow is you essentially take the your vote you encrypt your vote locally on your device using a shared secret that you get from the Gateway so that stuff here is end to end encrypted no one else can see in between it only The Enclave does at that point here then what we have is you send in the funds you send in your encrypted vote the funds stay in the contract on the evm side your encrypted vote gets passed to the Gateway the Gateway sends it automatically into secret Network where it gets decrypted and stored and then it sends the information to the voting contract that's also encrypted on secret Network and there the vote gets stored for later on then you do the voting your quadratic funding or your arbitrary curve funding that you like and at the end when it's done the private Gateway contract and the voting contract will just evaluate the tally look at all votes that you put in across all ch CH so what it does actually is it looks at the state of all of these chains it collected all of the votes from all chains simultaneously and it creates a combined Tally from all of them while the funds of each chain actually stay on that chain so it gives you a combined tally with a result and that result is then passed back into each of these contracts and then they do the payout separately because I mean since the address are the same on each AVM chain usually we can pull at you we can pull up quite nicely so in that case what we basically did is we did the whole stack using encrypted uh using encrypted votes and the votes actually never leave that contract anymore so we just get a tally out of it your vote will never leave it it will actually never be revealed at any point in time exactly here's the user flow again sorry yeah exactly no so yeah this is exactly the user flow um we quickly go over it but I can what we really like to show you is the is the demo actually of the page so some decisions are meant to be private we can quickly log in using metam mask so we have some test Nets here test net as well as fromia here you can create around for example type in something something some ID we can select a funding curve we do some description and we can add some popular projects that you might like we can then um this is then encrypted and uh we sign with it with our signature then we can send it into evm and it's done at that point the Gateway takes care of everything and sends it to se Network where where the whole funding project get stored then we can have an overview of the project and you can here vote for your favorite project and donate some giga away into it if you like exactly then this is exactly the voting and then if you voted something you will you can do that as well you can vote for some projects send him some amount your vote is known [Applause] congratulations 20 seconds one question one question and we also have a donate page to match some funding if you like yes what is the relation between the V and sorry say again um yeah you do so what you do is you put it in the front end so in the front end you put in your amounts that you are going to fund obviously and then in EN Crypton voted it should it should match it if it's not matching the contract should discard it yeah yeah thank you very exactly okay next up we have stealth key store I think this name I like the most because you can really get into it stealth keyto no okay fair enough cool anyone else want to give it a shot someone give it a shot stealth key short door yeah almost almost let's see if it's going to work I did like that the p uh that the slider was on the side for a second with the poll to see how degenerate that is continuing to go I is that your presentation in front of you the timer isn't top L you have five minutes starting now all right hi everyone um we are uh moris federo and Antonio outside of the zaton we work on fluty privacy preserving solution compatible with any evm chain specifically for this haathon with decided to hack on a concept called uh key store that has been recently presented by vitalic uh to give you the idea of the problem think of a world where you have like a lot of smart accounts maybe you already have multiple saves deployed all controlled by the same key but not visible on chain that the same key control all the smart accounts and you can instantly update or change that key within one single transaction ction basically this is how the key store roll up or key store works so specifically to here the first thing you have to do is of course generate a a private public key pair and register inside the key store this is what we are doing with this transaction by the way we relay all these transactions so the Privacy is preserved for the end user when the key is registered and it happens now then I can start deploy multiple accounts if you then look of this on chain in this case specifically we do safe smart accounts you will see that are all owned by different owners there's no correlation because there's a hashing in between there's no correlation for who is the owner here and with the key controlling them when then it comes to Pro prove a transaction this is where a ZK proof comes into place so for example I can decide to move funds out of uh this uh safe by generating like generating enough chain ZK proof that's fully privacy preserving and it's verified onchain while this is like from a technical perspective is is it's very user friendly the I think most important user friendly part is that if you want to change the key controlling all these Ste accounts smart accounts you need just to update the key store to do one transaction while not changing the actual owner of the different smart accounts and this allows like like great benefits and technically this can be also implemented cross chain with the key store being on a main chain either an L1 or L2 or a specific chain itself and then having the the the the the Merle tree hash root being propagated to other chains so as you can see here in in the demo we just did the transaction was approved if we go into uh click to see more and we check the actual data that that has been passed into you'll see it's quite a lot of data especially if you go on the final part of it as that's the ZK proof that has been generated that's like pretty pretty long one uh believe me that's yeah I don't know if there are any question but this was the cor idea [Applause] moderator questions we got got a minute how long is that Pro how long is that Pro how long is that how long how long does it take at the moment uh uh we are uh it takes like a few seconds to be generated I think eight seconds around eight seconds oh in bites to deoy to develop that we use the Noir language so we are relying on at technology under the hood okay one more question 3 2 1 thank thank you very much uh okay blockchain of things I believe is the next team uh this is the second last presentation let's see how we get on with getting it working I needed to charge my phone because it's running out of battery um so let's see what happens next how much is everyone looking forward to some beer yeah I know starting is no always looking for and also just a reminder in case you haven't scanned the QR code yet uh please join the qf voting and uh for any uh teams any hackathon teams that want to participate in the quadratic funding uh as long as you submitted through taai you can submit to uh participate in in the quadratic funding so be sure to do that today are we good you can also announce the next yeah all right I can announce the next guy go block sh things let's go thank you uh good evening everybody so yeah we have the blockchain of things and initially we had a different idea on the other screen sorry you can't see your No I can't but I I I can see on my laptop okay sorry ah oh right stop the time it's stop the time let's start that again let's start that again it's nothing ever happen I don't know what you did Starling but you pulled some magic I thinking to me the whole I can see the transaction I can see it yeah but you [ __ ] up you sent it to the wrong address ah I don't know who's ever done that yay like this I got paid in usdc what did I do I sent it to the USD smart contract thanks a lot it was I used a new wallet everything I thought I was double check in yeah sucks all right blockchain of things things of screens screens transactions I don't know maybe they're ready five four three two one all right you have five minutes okay so continuing where we left off uh initially we wanted to build uh a an ecosystem to solve the problem of oracles because blockchains need more oracles to have more connectivity with the real world but um we thought it would be best to incentivize the community to become oracles and how would we do that we would make it very simple for people to uh become an oracle on the blockchain like if you have a microcontroller or any source of data it should be very easy for you to publish it on the blockchain because on the blockchain there is a barrier of Entry you need to know some programming and stuff like that so we wanted to make it very simple um and we also decided that it would incentivize people if it would be um lucrative you know they have to be rewarded for the work of supplying the blockchain with information so uh we drew this uh drawing uh which makes it more clear so imagine that I have a physical sensor which I do this is a humidity sensor that we build um and I have a live data stream and I want to get it on the blockchain so that other people can use it or other I don't know AI models whatever um so the first step is to register this physical sensor as a smart contract on the on the blockchain so we register a instance of this sensor on the blockchain using the Oasis confidential evm why confidential because if it's confidential the data that get gets put on the contract isn't visible to everyone but it's only visible to the data consumers who in turn pay fees to access that data why do they pay fees to incentivize the physical sensor to yeah to be built by people it also costs money and time to put this together so they want some rewards for their live data so yeah in that way in in in that way we uh make it very accessible for people to become oracles um but then we decided to take this idea a bit further also and um you can have the centralized data on the blockchain which is also secure and is private there is no safer way to store your data than on the blockchain you know you cannot lose it and it's encrypted it cannot be stolen um we wanted to guarantee anonymity and Oasis helps with the tool because transactions are encrypted um the arguments are also encrypted and everything in the contract program is encrypted so no one can just look at your data um and yeah so so a question that we came across a lot was how do you ensure that the data is of good quality so we implemented an anonymous voting system everyone who is subscribed to a certain data stream can also up Vote or down vote uh based on their opinions of how good the data is or how reliable the data is so that way we have some sort of control over the quality of the data so so as I said we have we have built it didn't take long a humidity sensor ourselves which is actively on its own communicating with the blockchain and it's putting the data on there uh so we have a demo but I don't know how it's going to skip we're working on six hours of sleeping 48 Hours soon and it's difficult to acheve from here so yeah yeah that's the demo um so like every every good demo begins with connecting metamask and um so you you have the devices which are very secure that's why you have to sign a bunch of uh for security I'm being Rob I'm being robed take my keys oh no did you lose it and then almost there I got I got very good at doing it quickly while debugging it so okay we getting that hey [Applause] y okay we are there okay yeah so go all the devices we still have 7 seconds and um no not that one not that one yeah so one of these contracts is the the smart contract instance of this humidity sensor so we can look at the live data you can see a relative humidity of about 32% very stable which is good good h here and um I was then uh when I was sitting there I was blowing into the sensor for uh 10 minutes so that's the [Applause] peak the most secure sensor I've ever seen in my life really cool now we have jpeg station and oh oh hadn't heard that one one before okay let's see if they can get their jpegs to align with the with the and uh see how are we doing Mr non name good energy you good yeah still with us we're almost perfect he enjoys the process is everyone still having a good time yeah do you think we've seen cool [ __ ] cool oh all right uh are you ready we are ready okay you have five minutes starting now okay thank you thank you so much guys so basically we are building a JPEG station so jpeg station uh is a contract that enables cross chain contract swaps between nfts and ordinals so in different chains of course so let's see uh basically we have some benefits the the benefits are uh you can just use wallet so no metamask unot or whatever it's the near wallet uh you don't have to bother about the chain because everything is obstructed and uh you also don't have to relate to Bridges Sexes uh FTX or or whatever so you will be safe with this probably and uh yeah hopefully so uh yeah let's just see how this works okay so let's say Lisa as a m lady and she is missing out on puppets which are going to the Moon basically on bitcoin so she wants to create a uh order and uh she calls the contract that is on the near blockchain so the M lady is transferred to this contract which is an escrow so um there is also Bart which wants to get rid of his puppet for some reason is just stupid prob probably so okay after all the nfts are locked in the contract uh the escrow is settled so um yeah each user can retrieve to the correct address uh is nft so the exchange uh works like this and it's the thanks to near because near uh has accounts that can be which you can derive other accounts so you can derive an ethereum account and BTC account so this is the magic behind all the thing uh yeah so let's give a look at the application with yeah let's see this is not the application this is the application so yeah this is the front end of the application and as you can see uh we have a list of orders on the left and uh I can see that Kaz has wants to get rid of is Mady for and wants Bitcoin puppet so I can just uh create an example trans transaction where I want to get rid of my uh of my Bitcoin puppet and uh let's get uh M lady so let's uh create the order and it's going to prompt for my password it's mine sorry and uh it's going to return to the once it approves Wi-Fi by permitting is going to return to the website and it's going to update the list of orders with my new order so yeah that's it when a user wants to receive the uh accept an offer and uh start he can click on accept but this part for D aaton we is not yet completed don't say it ah sorry but father yeah let's [Applause] go and I can left yeah any questions what's your name thank you awesome awesome awesome beans right that was the last last hacker presentation of the top 10 so please give everyone including them every single hacker a huge round of applause wo all of you all of you have done such an amazing job um we want to definitely take a moment to thank all the mentors and all of the judges who went through 60 presentations um and 60 demos and all of that and these were the short list remember there is the quad dratic funding so please pay attention to that and uh please participate because this is how money also will flow to the projects uh I think that's everything for that so now I'm going to move on to the partners who are going to announce who won their bounties so that's more money going to them amazing um so um that is where uh the first partner that I would like to invite to the stage and for all the partners it's going to follow the same thing I'm going to ask you to come up stage I'm going to ask you to announce which Bounty it's for and then I'm going to ask you to announce the winner the winner does not have to come up um so it's just that announcement and then uh we're going to go on to the next one so first up I'd like to invite trail of bits woo wherever perfect so we need the microphone thank you okay um yeah so for the 12 bits hackaton we are the 2K prize for slitter and we have two winners the first one is critic Shield which is a telegram bot uh that leverage liter and and machine learning to allow any user to ask question about a specific contract and the second one [Applause] is and the second one is ml prediction which leverage slitter to create machine learning featur to kind of evaluate if a contract is going to have a certain um market cap cool thank you very much thanks everyone did you say uses Twitter Twitter okay okay I was going to say no all good thank you very much appreciated and the next one we're going to invite up is threshold oh it's James oh my God I don't know that shouldn't be a surprise so threshold had a 2K Bounty prize I really love this project for the simple fact that it's going to save me personally a bunch of development time I now don't have to build it uh uh Taco snap are our winners they yes thank you so much uh they've implemented our endtoend encryption Access Control into a metamask snap which is going to make it much easier for our adopters to on board and get involved with our ecosystem thanks very much guys thank you thank you third up we have [Music] waku yeah so we always say people building on waku everyone's a winner if you build on waku and it quite it turned quiet literally for this event because all the projects were built on top of waku is a winner so the first prize would be for stealth aloc so you win the first prize yeah we got some yeah and the runner up would be shared by two teams uh the first one would be brain computer interface and ingenius both of you will be sharing the second prize cool thank you thank you thank you very much um next one number four is near woo thanks thank you very much hey uh thanks thanks to all the hackers thanks to eat D this has been an amazing like venue and amazing event and it's been very hard for us to judge and here we're going to be presenting who are the winners for our hackaton partnership Owen wait I've got him oh I'm joking no you're I'm joking that's why I don't want to go on stage with this guy right we had we had so many good ones so we had to split them up so for 1.5k we have 2 fa clap clap at the end because there's a lot and for 1.5k as well we had feedback and then for a thousand we have Neo and then for five then for 500 we have secured jamm jpeg station octopus layer and kudas nice and and just well you can't control them man you can't control them you got to let yeah I just want to say that everyone who was building on year like you built amazing projects and we believe that you have a part of like you have a spot in our ecosystem and our community so reach out to us and let's uh try to partnership and bring your projects forward thank you very much thank you very much eth thank you thank you then we have the second to last psse [Applause] hey when I say p you say privacy what's up party people we're privacy and scaling Explorations guys we do we build public goods on ethereum using programmable cryptography if you want to learn more come check out our booth just kidding the booth is over we had a great time with you guys thanks for the great questions great enthusiasm my my favorite hackathon so far um we had a a few different bounties a few different projects uh for Builders on Macy the winner was zerox feedback they did a privacy preserving B Toc survey platform um stealth aloc number two getcoin grants Alo protocol using Macy for privacy and third was Neo um yeah wow um nvo built uh Macy uh cross chain using near cross chain signatures sick sick sick uh bandata also gave out three prizes zerx 2fa first place congrats wo be Hook second place how many are there and last place well third place brick wall congrats thank you guys that's super I was just surprised how many bounties there were that's so cool really congratulations to all the projects that have uh that have been racking up the bounties congrats to you guys I don't know why but I'm happy for you um and so the last ones to announce their B bounties is of course Oasis woo [Applause] wo that that microphone if you want to use that one you can use that M can I use sound perfect so uh first of all I just want to say thanks everyone uh thank you for being here all the hackers uh all the attendees speakers sponsors and uh last but not least the people that made this possible the entire crypto Canal team and the volunteers let's give them a round of applause guys [Applause] so I I just want to say that it was very very hard to decide on the winners because we had 16 teams building on sappire very difficult decision uh but it has been very refreshing to see so many uh developers passionate about privacy so yeah great job guys uh you were all absolutely amazing um but we did have to pick six winners uh so without any further ad let's move on to that first of all we have the winner of the AI bounty in the amount of $2,000 uh and that is PR ad an advertisement tool congrats [Applause] guys then we have two $1,000 bounties and they are going to Black SE a dark pool solution and blockchain of things again congratulations guys moving on to the podium and I will ask uh these winners to just come here by the stage so that you guys can grab your consoles as well so for third place with Bounty the amount of $1,500 we have be hook a crowdfunding tool for Content creation so guys just come here to get your consoles and then second place Cas with amounting the the amount of 200 $2,500 uh goes to 0 to 0x2 FAA uh developing an onchain to factor Au authentification tool and an integrated multi these are a lot of very complicated words and I'm Eastern European so yeah and now for the big winner in the first place with a prize of 4 ,000 we have O's [Applause] guards congratulations guys congratulations they built um pasy integrated onchain password manager and that was a mouthful nice [Applause] super cool super cool stuff um thank you so much thank you to the partners also the bounties are they uh you want to they're going to be around I think are we going to how do we want to do this you want to take photo I assume you want to take photo do you want to do it here Ellie I'm going to look at you they're just doing it there yeah okay um all right so that was the partners presenting their Bounty super cool Distributing the cash uh super super nice um I just want to say something a little bit about my personal recap of of what this weekend was just as a very quick summary so we had all the Privacy stuff in the on Friday which was super cool we had the security stuff on on Saturday and then we had the regulation and compliance stuff on Sunday and I hope that for each and everyone you ended the content that you could enjoy privacy is important to every single one of us it's been an absolute pleasure to be here and it's been an absolute pleasure with Starling as well have you enjoyed yourself I have I have yeah absolutely it's been such a pleasure and just such a privilege to be sitting in this room with people who you know were building uh tools for privacy you know in the 1900s to then also see how that's really laid the groundwork all the all the things we've built so far but then also to understand like how much farther we still have to go you know so it's yeah it's been a lot privacy infrastructure is further along than I thought it I knew it was and you the people here building on top of it are the ones that are going to power it and so what I'd like to say is I'd like to end and leave you guys the way that it started and say that this is [Applause] privacy you're up Ellie [Applause] oh it'll T when you start speaking all right and now without further Ado we have the eth dam mummy Elanor [Applause] block I'm not a mom yet but I do feel like kind of a different mom towards all of you and a very special way it's always so special to work on something for so long and then seeing you all in one room together and making more uh project and more babies into the space basically there's a there's something really uh going full full circle here um we basically had now a 3-day conference hackathon moving from our previous Edition we had a magician a playroom and once again I wanted to make sure that we were not afraid to be political um I want to drive this home I started the hack hackathon in the same way but I wanted to make sure that all of you once when you were building for these 48 hours that you know that this hackathon this conference is very much dedicated to a certain ethos and of course with in mind all the builders that are making a difference and bringing more financial privacy to the world and of course I'm thinking of Alexi who is here for a few days with us um he will have his sentencing in a few weeks so we will know if he has to do five more years in jail or not this is what's hanging in the balance here in the Netherlands we have 22 partners that believed in [Applause] US 22 22 partners that for some reason really also are aligned with what we're trying to do here so I would like to give a round round of applause to Oasis near trail of bits privacy scaling exploration waku drpc threshold Avalanche Lio Panther protocol Expo Fern Maven 11 chain security cyber Capital Diva secret Network ZK sing beefy obscura z b and the ethereum ecosystem Support Program for making this [Applause] possible this industry is not neutral all of these people all of these people that we've selected and worked with for the last few months not only do they believe in what we're doing here but all of their products and how they work and the eth thoughts that they're building in their own companies and their own projects you were able to EXP experience in a way during East because look at these funny thank you Palos our amazing photographer and Jen for also walking around and capturing these moments these candid shots during a what my time's not up I decide um for the conference side we had more than 200 applicants I hate saying no I I hate that process uh but Emily here in the room also helped me a lot in PG and others to go through that list and have the really hard job of who do we platform who do we want to hear what are what are the messages that we want to share with you what is the type of content that we want to yeah put into the world basically what are the hard conversations and maybe the more edgy ones that we don't hear all the time to make well the best content for you but also for posterity so thank you to the 80 speakers that we selected who gave who traveled some well some just biked here but some really came from really far some came from really far just to to share a glimpse give you a snippet of their research or or their work uh with with you so all the content of course is going to be available uh online and we were happy to also live stream it and the chunky piece the chunky lazy otter as well yeah some people say we might have too many logos I know it's a bit confusing but this is one of many we had 382 hackers applying for this hackathon and that's a very special number and honor to have all of you here um we had 237 last year so really I'm really happy to say that we had 20% out of that 20% of you were lumiz so I'm not sure who was here last actually who was here hacking last year yeah you see you're 20% but it's really nice to see all these new faces um joining e Dam so this time we give you a little bit more time we gave you 48 hours I think it was it could give you just more time to maybe for the team building and stuff like that so I think I would keep keep that number and 60 plus projects came out of it 30k in bounties thank you again to all of our partners for making that possible and 15K in Macy in quadratic funding which all of you here are still part of JJ has been Hamming you down for you to go and give us your eth address but it's basically so I didn't want to use the Moongate thingy you know you all got an nft and you all got an eth address through that but I wanted to make sure that you could just use whatever eth address from whatever wallet you were comfortable so that we could give you then eth Dam tokens which are only there for the voting process but um yeah this hackathon would not have been possible without our army of volunteers that [Applause] slaved and I would like to welcome them all on stage with me right now everyone that made eth Dam possible please come to the stage come next to me and just have a feeling of what it's like to be here with me and Round of Applause for them Round of Applause for these volunteers that for the last three days took really good care of you made sure that you would find your wallet or your [Applause] phone some of them are already working in the industry some of them are curious some of them are students Etc but I would like to just say thank you from the bottom of my heart to all of you for dedicating your time and making eth them special for for all of you here so once again thank you to all the etham volunteers look at that look at [Applause] that yeah James what are you doing you see it's trying to hide yeah you can't hide you can't hide in that case JJ as well yeah JJ where are you Sterling what are you guys doing EFM e Come On Stage okay thank you thank you [Applause] eam and together we can announce the best privacy project of etham ZK loyalty ZK [Music] loyalty come on stage are you a this was like this is this is the Crown Jewel for us is to make sure that out of the all of these projects hack hack of the hackathon judges mentors W do not fall off the stage Jesus congratulations congratulations dky congratulations congratulations and then the next one are you ready for best security Oasis guard W Oasis guard if you're still here they might have left they're playing with the consoles you're playing in the back that's fair enough well thank you again to everyone thank you to all of you for having yeah I don't know for making this special and out of this whole journey of organizing ethm I have a court team that has made this very very special that has allowed me to just survive what no not too close it's [Laughter] too um piji Federico niceta Emily all of you Sterling JJ and of course where are you where is and Tara in the middle who's hiding [Applause] I I couldn't be doing this without them they they made sure that I learned how to delegate that I could actually be pregnant and do this whole thing and you know not give birth on stage or something like that um but yeah thank you once again to all of you for yeah really for your time for your dedication for believing in eth them for for being part of this crazy crazy crazy process and um yeah I'll try not to linger too much I I'll get emotional yeah okay Oasis guard congratulations thank you so much and so they all get chocolate and then they also the two winning teams of best privacy and best security you all get a ticket to Defcon 7 southeast Asia that's pretty [Applause] good uh so yeah see you in November uh in well I won't be there I'll be breastfeeding or whatever but um that's the next one that's the next big face for a lot of people but uh I'll see you uh tonight at 7 pm at Aloha this is kind of like a crazy place it's like bowling and Laser Tag I'm not allowed to do the laser tag I find that very discriminatory um and karaoke and a bunch of stuff and I'll see you next year for EAS M 2025 [Applause] [Music]
