[Music] Hi everybody, I'm Leona from Inbox and yeah, let me give you your presentation about uh beyond human machine to machine transaction with stateless layer 2. So inmax mainet launched uh know five days ago and it's it's been a while we are building inmax and before mainet launch we spend a lot of time talk about the how it works and what the functionality of inmax but no finally we can talk about kind of more near future

after main launch. So I'm super happy to have this one. So yeah let me introduce myself a bit. I'm Alona and basically we I'm one of the architect of inmax and I spent a lot of time researching plasma no since 201 18s or something like that and yeah basically intmax was intended to be a kind of perfection of plasma so basically uh haber say almost same scarability of plasma which scales with let's say 01 and other one and also we have privacy and we have almost same half security assumption zola without

online requirements. So I want to say that this kind of perfection of plasma but yeah let me uh explain uh how we kind of expander possibility of the stateless layer to like inmax. So one of the idea is like the machine to machine payments but what's the meaning of machine to machine M2M payments and why do we need crypto for that for example so we have many devices today right so maybe no more than no 20 years ago no we have more and more devices and no Raspberry Pi know many kind of know kids

are no like you guys know No, no work with this, no play with this, right? And also today we have like chat GBT no kind of new innovation three years ago or four years ago and we have kind of way more like uh no more automonous uh self-driving cars recently. So world will be like more machine-driven society in the future and in that society with new or you know let's say architecture what kind of payment do we need for that

so it's bank enough for the future payment which is totally deviceed driven or machine driven. So if we have a API key of banks, why do we need crypto for machine to machine payments? If what's the difference? No, machine to machine payment and human to human payment, right? And no, some of you guys said no can say that no paying is human job. No, having responsibility is human job, not not machine job, I guess.

So but we can know make it clear with really simple questions. So how many bank account do you have right now? I have three and how many maybe less than 10 basically right and how many devices and AI chat thread do you have? No devices. No, we have no many things like no laptops, phones and the Apple watch let's say no Raspberry Pi in my house. Uh know many many and why we don't know how we have devices inside machines like you know uh refugees uh refrigerators and yeah actually there are so many

devices are know inside our house and inside our lifestyles. So maybe I guess like no it's 20 my no lifestyle and also if we talk about the how many chat threads we have in kind of AI uh LLMs like chat GBD or no cloud no what whatever you want to come up it's it's like no over 500 right how many crypto addresses do you have I have maybe 200 or something like that and some of you guys No, over a thousand maybe. And it's like no, it's like crypto, right? And why do you have so many addresses in

your wallet? Because you have many devices, you have many purposes, right? That's the only the reason why you have so many accounts in your wallet. So if deviceriven society uh which is totally driven by kind of autonomous devices and AI we need more devices we have more devices we have more purposes. So in such environment we need more accounts not like three or 10 which is which can be hosted by bank accounts.

If we go detail in the kind of future uh security regarding the uh no machine to machine payments uh society we need come know we I can give you some example like no offline to offline payments so if there's a device here or there and sometimes devices cannot connected to internet right but I can connect to internet so how can I pay uh to that devices are walking along here. So if if it's banks no both devices of mine and the another device I want to pay to

both of them need to have online connection right otherwise it doesn't work in in banks banking systems but in crypto we can pay with proof of payment return by blockchain and we can prove that the hash rate know we can prove that the block production on the client side on the machines without connections they can accept this payment right so it's more desirable payment architecture in or in terms of the know device society and another part is like okay there's trillion

devices in this board and in the f in the near future maybe more and in this kind of huge number of devices or set along their cities and societies how to let them pay from their devices. So if we share API keys of bank accounts and we set that in each devices now even one device is compromised the all the security will be compromised right. So this is another reason why we need a kind of device uh which is protected by cryptography and

separated by cryptography architecture. And another demand of the machine to machine payments is like cross border. So actually I have a one bank account card in my wallet uh in my kind of purse. Uh it's in Nigeria and I have a card of Nigerian bank and I have a card of Japanese bank account and also Switzerland bank account but I can not find any method to send money to to this Nigerian bank account actually but no if crypto it's just no it's it's it's like

three seconds or two seconds right so actually the crossber border transfer it's more expensive it's more difficult it's more somehow irrational uh based on political reason uh which cannot be fixed by machines right so in terms of that crypto payments it's more needed for machine payment in crossborder uh kind of department so yeah we have a no website which is free to access right now right and why don't we have a device which is payable and accessible in another country do you have any

machine you can operate in another country right now maybe not right so in the future in the quite near future know we we are totally possible that uh to access uh device uh which is which we can incentive with crypto and let's imagine that you want to buy a small room in Texas. Uh you want to set up furnitureures of rooms of that room without people hand at all because it's cheap. Can you operate that uh no that kind of uh remote uh operation uh with your laptop with your bank account this is more crossber payment which is more

crossber transaction which is which should be safely delivered. So in that sense crossber payment is totally crypto stuff instead of bank accounts. Okay. So what is the most desired payment uh for this machine to machine payments? So I want to introduce stateless layer two on this concept. So stateless layer 2 is more like extremely cost minimized L2 and it's it has more privacy. Of course, there's a

trade-off like uh no more functional uh less functionality or no more client side device side uh cost or kind of burdens but we have more efficiency uh regarding the gas cost on on chain and we have more privacy which is totally out of par no which is totally untraceable uh in blockchain explorer or any kind of chain. analysis services and how cost minimize that it's so maybe we are the one of the no good uh experiment uh of this uh region of this

department development inmax launched the mainet know yeah five days ago and right now it's almost 0.08 And there eight bytes block space consumption per transfer meaning that it's less than one bit right so one transfer is less than one bit one bit uh this can be done simply by uh no sharing one transaction uh with many uh transfers and one transaction is like five bytes and you can and you can include 64 uh transfers in one uh transaction in in that five bytes transaction. So that's the meaning uh of the 0.0

78 byt block space consumption and block space consumption is including blobs. So we can scale layer tools more than no the other L2 of course and basically there L2 consumes there more than almost 100 at least 100 bytes per transfer. So this kind of bite is like a Guinness record of the kind of onchip minimization part transfer. So yeah, of course there's a tradeoff and because there are so many great uh people working on crypto u some people optimizes theirelves to to another

purpose more general purpose or yeah whatever they want to kind of chase but our system is more kind of making extreme efficiency and privacy at the same time and almost nothing more uh let's say we have a more decentralized sequence ers I will talk about that later. So okay intmax is one of stateless layer two. The other stateless layer too is like uh no it's quite different from inmax but it's like lightning network for example it's it's stateless and so what's the future of intmax so inmax is basically payment focused layer two and

as I said before it's extremely minimize DA consumption and maximizing privacy and what making this quite strong feature if I summarize that it's almost it's it's like data stage and ZKP computation on client side what we call client side validation so if I summarize this system it's like a client side validation plus recursive ZKP and so maybe there's many ways to express this system in many ways or know and make a metaphor of this system. But I think

that know these four are kind of really good way to make an imagination uh with uh currently shared uh project names. plasma plus recursive ZP it's quite direct no uh expression on RGB on Bitcoin L3 no it's like a yeah proof distributed payment system and if we apply Mina plastic up know maybe we can make a same uh as max and maybe you know it's a controversial but you know the shield CSP is no bitcoin layer 203 which is totally applying the RGB plus Mina uh uh which is published by Boxstream. So

yeah, we have kind of no stateless browsers but intmax it's quite special simply because it's actually providing 0.0 uh 78 bytes are no minimized uh transfer right now right here. So if we go detail in the no uh tech stuff it's like no we have a communication between block producer and the senders let's say and senders and block producer there's a communication of proof distribution and the signing back

signature and send back sending back that to to the block producer and this communication is compelled by uh ZKP circuit. So if you skip this communication hard know your transaction will be canceled. So yeah kind of automatically and so yeah this compelled uh forced communication in Zip circuit uh is a quite unique feature in even in stateless uh browsers and so the proof of the asset will will be certainly delivered to the client side and yeah people you guys can keep that in your wallet on client Right.

So this hover end address chain of ZKP because no sender no if I send the money to you I get the proof and the I will send that to you with ZKP and why the recent ZKP why the recent payment is right to no accept simply because the previous person was right and the proof is not faked right but why previous person was right and how how to know that it's it's previous previous guy is right and he has a proof so we have a kind of chain of no proofs and it's it's totally same as our

RGB actually but if we apply the ZP magic happens so chain of zip you can imagine that previous ZKP already proven the previous previous ZKP right on the previous previous ZKP already proven their previous previous previous previous previous ZKP and you know it's reaches the origin right so once you verify the previous ZKP it means that entire history of ZKP is totally correct and you you don't have to care about that know to the end right so just ZKP is fine to prove and verify to accept money or send money so it's totally constant cost

and yeah in terms of computation and the data storage. So yeah many things happening are know in this kind of uh no mainet right now and the I spent a lot of time in ESK no two weeks ago in in Ukraine and so many people uh could make a launch your privacy scalable privacy application on that uh please visit and please join their mining of our system as well and so yeah thank you so much and let's stay in stateless [Applause]
