 Když je o výsledním, co se to náloupé, základí jako tato! Chtěl jsem jen, a tohle to je o stoceně hodně na výkhodosti, tak môžete kumianý urč我覺得 někdy bylo to vysepet offices. To je zde výkodstvo, že tam přijde to a to přijde na základosti. To, co se závodilo, je to, že ta informacična o veliké přímovětí výzvodní hodinu a tedy, když je to výzvodná, tedy byl to vysvědný, že to bylo výzvodný, aby si návodil výzvodný a když se vysvědný výzvodný výzvodný. A to bylo závodný, když to dělá výzvodný. A takto situáciní strany na wéb3 jsou záležit. Abych, který můžete vědělat web browser a budete mít v Ethereum s tím, jak tyto také chtořil. A to je spět od nebo bychom těkídí s pengy SNS takže náščit celý príjem, že je poprvé, že to říká, comprena 정mi náky SNS, když je uvrnit nejde, že to je nejsou vždy. A by vytrтакí toho dobu prostě záležit, tak se záležit, že si figuredu snad nejení. a se než akumulátivnou, co se jeměme vytvědět, že úli můžete na nějaké lívice pro zvuky. Ymejte, že to je n Hz, protože plný odtím je náš většené, že vysvědom je to poprvé většené. A když máme pěkní o financiávené informace, to mohlo byť zasavit, protože je to návětne jen, je to about to assess solvency of entity on Ethereum and this information can be used by adversarial parties like MEV bots. And then there is also of course a risk of doxing and consequences in the physical world. This can be as innocent as your friends, shaming you for your bad traits, but it can also make you target of crime. So the solution at Aztec, we think that the solution když jsou všechny první zvukování a první zvukování a první zvukování a první zvukování je zvukování Aztec Connect, to je vždy na mainnet a my chcete zvukovat VPN na Ethereum a my myslíme, že to je hodně nejlepší mentalný modul, protože všetně co VPN je v těžkém vědětě, je to, že je to zvukování jen IP adresu, zvukování jen IP adresu z vědětě. A zvukování jen je, že je to zvukování jen Ethereum adresu s Ethereum adresu aztec. Takže bychom bylo dělat večeště když padne dělat večeště večejte, ale to době je to ne Didn't do vědětě. Takže tak bychom bychom bylo dělat večejte, protože když vyvědětku Kindersky, horu kteří, kteří nezapravit se zj enhancing, kteří ty se připravit na nápadku Ethereum na rootinu. A to bychom zavodila, že to bylo vědětě, takže bychom byl po vědět HoD. A to byli vědět, že to byli vědět, že to byli vědět, thear� of transactions. Behind the scenes you get a transaction happening behind the scene. The new deposit the amount of funds. Behind the scene there is actually happened quite a few things. There happened two transactions on Ethereum and one deposits the funds into a parallel processor contract. Another approved this hash and then there is like a generation of cryptographic notes on L2 and this cryptographic note normalo volet. And then there are opportunities so you can deposit into an arbitrary bridge we've implemented. For example, if I deposit to Euler, I have this screen. And there are quite a few interesting things here, which I want to explain. First one is a batch. So there is quite an interesting feature to Astec connect. And that is that we allow for this thing called batching. istotne, co je třeba mětněfáka, když je raptor na léjí Úéri. Děkujeme vám, že na léjí Ú cumpliply úžití i to základí.

A pak nápadáme v tom, co bych ho udělali na závodě a v tom, jak to bych bych bych potlustět nevávodět, co bych nápadal hr. Taky musíme předlovené ukryti, co je v tenhle závod, které se nápadali na závodě, co bych nápadal nevávodět, co bych nápadal nevávodět. které ps Suchail, kterou je výtud, které má tu nači nepřidět, které je mají jen původskou, které je původskou. Teda abych měl, že co přijde s pátkoho pridženého. Ale klidíte prostžit тем, které je pridžené, ke které se veni obyka. Otsahá s dvířenou to z trickybu mi zelnějí.

Over the prezipof of the bridge interac, of the defiedepozyt to LIDO, on the input would be, for example, 0.5 eth, and in case the original value held in your account was one note with one eth, this note would get destroyed, and on the output would be this claim note and another value note. That value note would hold the remaining eth balance, it would be 0.5 ETH and that claim note would allow you to later on claim the funds resulting returned from the DeFi interaction. So you might be asking how is this possible that this is private when the settlement, the interaction actually happens on Ethereum. And this is a good point. Here in the left bottom corner, we can see what it looks like, what token transfers a to je všechno však výjedecky, ale zvuk je, že mělo největné zvukovat, neskoušel nás nebylo našel, který by se přiděl na toho výjedeckého.

Vysvětně výjedecké kosty a výjedecké kosty je to, že měli měli úžitý úzor, takže, když měli úžitý úzor, to to se vysvětne.

An we might be asking if there is some limitations. And you gave quite a few, I would say the biggest one are the longest settlement time that is because we have to wait for the batch to be submitted to to Ethereum, like luckily it can pay when it is in the hurry takže můžete půjde na plný rolaplok a když můžete dělat tady instančný sételmen tým. Ale můžete být zvědět, protože je to velmi zvědět, a to je takový problém s slipou. Protože můžete zvědět, když jste na Unisvap, když jste zvědět s slipou, který zvědět zvědět zvědět můžete můžete můžete můžete můžete můžete můžete můžete můžete můžete můžete můžete. A MY期 associate s sételmenem můžete můžete můžete můžete můžete zvědět protože můžete můžete můžete, když jste sételmenem a můžete můžete vlastně vytrýt tým škotem i takost, kterou můžete projť vůladit a převno vysvědět sa tím sételmenem. A to je nogé tvůj sételmen bychom základ montáru, který by mohl být na úlídě, či můžete můžete můžete můžete výdět protože je 64 důlady bit of smart encoding we can actually put a lot of information there, but it can be problematic when we, for example, want to pass in a theorem address because that is 160 bits. Then another limitation might be that the system doesn't work that well with esoteric tokens because those esoteric tokens might have insufficient anonymity sets. And basically what that means is that there is only like one esoteric token user and he would deposit into us tech and he would be the only one working with the DeFi protocols. It would be pretty obvious that is that one user. But in practice, I think this is not that big of a deal because usually users want to use the high liquid tokens and I don't feel personally that it's such a big limitation. And another limitation might be that some protocols are specifically designed to work with message sender. So, for example, when those protocols just work with tokens, you can imagine that there is token on the input and token on the output, which is, for example, the case of LIDO, like this works perfectly because there is no limitation. We just have tokens on the input and then we distribute the results. But when the protocols work specifically with message sender, which can, for example, can be when we are borrowing LUSD from liquidity, it's pretty complicated to do the implementation. And how we've solved it is that we deploy these multiple bridges and each of the bridges have fixed collateral ratio. And, like, if the bridge was, like, close to being liquidated, user can't add more collateral, but the user can always repeat the debt and exit. So, even though there are limitations, usually there is, like, some way how to work around them. Now, I would like to talk about advantages and I think those advantages are pretty huge because Aztec Connect doesn't need redeployment of smart contracts on L2 because we work directly with smart contracts on L1. And this means that, for example, liquidity is not fractured. And I did my own personal experiment when it was bull market and I checked, like, how much it makes sense to do, for example, swap on L2. And it turned out that for not so large amounts, like, over $5,000, even with the high gas fees, it still made sense to use Ethereum L1. And that is because the liquidity was just so much higher, so the slippage would be just so much lower that, like, the fees would be worth it. And another advantage is a lower risk for integrated protocols. And that is since we don't need to, the target protocols don't need to, like, redeploy again on our L2, there is no risk for them, like, for example, the risk of fracturing liquidity. Then I would like to mention that there are also, of course, non-DIFI use cases, but DIFI is, like, a nice buzzword, so we mentioned it here. And I think a very cool use case could be private voting, and that is because in all the voting systems, privacy is very important. And another interesting use case might be NFT minting. Yeah, thank you for the attention. Thank you, John. We still have questions. Time for questions. So here to write, Nicole. Ah, yeah, I can put that, I can let it out. Podemos poner la última slide, por favor. La presentación de John. Yeah, just a quick question. How expensive is, here, here, here, sorry. You're looking for me. How expensive is each operation, because it seems like you're doing complicated cryptography and solidity? So on Ethereum L1, it goes like the same as I mentioned before, like the call itself, and then there is the cost of call data and processing the rollup. So does it answer the question? Like, I have to admit, I'm not a cryptographer. I'm just like a basic solidity engineer. Well, as well. So, yeah. So it's not very expensive. A second, can this work on alternative chains, like in other L2s, like when in Aztec? OK, so our contract is implemented in solidity, so we can deploy to any EVM chain, and like our L2 infrastructure just uses generic JSON RPC, so like there is no fundamental issue why that would not be possible. But like an interesting note is that it might not make sense, because usually those other L2s have also like have to post the call data on Ethereum L1. So it means that if, for example, we're running over optimism, we actually would not save much gas. We have one there on the left side, then there, and then the third one. Thanks for the talk. You mentioned you have over 50,000 users on Aztec network. A couple questions, like who has integrated besides Euler, like who's on the docket, and like what are those 50,000 users using it for? Yeah, so we have quite a few integrations. I think the most important are, for example, LIDO, Euler, then we have Yarn, we are working on Uniswap, Liquity, and yeah, we have a grants program where we basically give some developers money to build the integrations. And yeah, that's it. And where are the users using it for currently, mainly? I think that like in general, the farming worlds are quite popular, so we have quite a few users of Yarn, and we've also built this thing called DCA Bridge, which allows users to DCA into ETH or DAI, and it's also becoming quite popular. DCA is dollar cost averaging for those, which I don't know. I got the mic already. So one of my question was around what you're doing to try to deal with this settlement, like leading times and stuff. And I was wondering if, as you integrate with other protocols, if that breaks community or brings in composability challenges and kind of how you're thinking about solving that in the long run. Yeah, so there are no composabilities challenges because it's running on Ethereum L1, like the calls, and the best how we can deal with the settlement times is basically having enough users that it's profitable to submit the roll-up blocks frequently. But as we said, if there is some user, which urgently needs it to be settled, he can always pay for those instant settlement. How much does it usually cost if it's just one user, or it depends? I mean, when it's batched, currently it costs one dollar to deposit into Euler. Thanks for the awesome talk. One example you gave at the end was a private NFT purchase. Does that mean the NFT will be owned by the Aztec address? Yeah, exactly. It would be owned by the Aztec address, but we don't currently support NFTs directly in our UI, but we have this thing called Virtual Assets, which basically allows representation of any ownership. So, on Ethereum, of course, it would stay within Ether, within the bridge. It would stay within the bridge contract, but the user could then interact with it by using the Virtual Assets. Virtual Assets, basically, what it does is that it doesn't exist on Ethereum L1, but we create this another value note on our L2, which contains the information, which can then be passed to the bridge and worked with. So, yeah, it would stay within the contract on Ethereum. My question is, can you do scripting logic on the L2 itself? So, not on a bridge, but within the L2? I mean, it's not accessible to developers, but it's possible to build circuits. But it's not the goal of Aztec Connect. We will have generalized smart contracts once Aztec 3 is available, which will be in a year or more. So, things like multi-sig on the L2 itself, that's not really possible yet. Actually, there is an implementation of multi-sig. It works with the account cryptography. So, yeah, we have multi-sigs. Awesome, thanks. More questions? Test, test. So, always a fun question about regulatory risk. Obviously, this sounds like a mixing component, similar to Tornado. What are your thoughts about that and that risk? Yeah, so currently how we approach it is that we limit the deposit size and basically our goal is to avoid the use of hackers, avoid hackers using our platform. And the big issue with Tornado Cash was that 70% of the money there was illicit. So, basically we are just trying to make it impractical for hackers to use our platform. What's the limit? What's the limit? I think currently it's like 10 eth per deposit, but we might increase it in the future. Okay, thank you. Can you share a little bit more? I'm over here in the front, right? You're 50,000 users. Can you give us a sense of like, before Aztec, what were they doing? Were they doing the same thing just totally in public? Or as a result of Aztec, are they now doing things that they previously weren't doing? I'm not so sure how to answer, but I would say it were like, general defy users, and they just wanted that privacy, so they deposited to Aztec. But I actually didn't do the analysis. We have four minutes more. You have any questions? You have John. Has been really brave to substitute the CEO. Congrats, big round of applause. Just prepared this. Thank you. Thank you.
