Hey everyone, my name is Gregori. I'm now working a rollups. Previously I was busy involving eptos and fuel ecosystem build some trade and defy apps and doing my web three research. So yeah for now all of you who have a question why I need a blockchain and what's the reasons for me and uh to answer to that I will start from from the scratch and make a step back to to this morning. Uh what do we see this morning? When you wake up and go to Twitter, you see a lot of success tweet from the leader uh leader phone industry, the a sui and all of them says, "Yeah, we have new TVL record, we have new milestone, we have billion user and all of this and uh so question raise your hand if you at least once a week thinking I should I should something similar. I should build and create project which change the game and uh yeah this is uh I'm my project will be the next unicorn. So uh yeah very ambitious that's cool and uh I totally respect all this company because they have an incredibly uh difficult path to to build this uh project and to be the industrial leader. uh but to understanding their success we need to to see their path and uh check what happened and uh what stage are they have and uh yeah typically all of a project has a free stage the first one is idea and this is my favorite part because first of all you don't need money for this stage you create a notion you collect a lot of ideas you shield it with friends we you discuss and check product hypothesis with venture venture capital with other web3 builders and when you clearly understand what you want to do uh you start to struggle with development because it's doesn't matter what what area of product you want to build the dein rwa the defi it's uh all of this area has a similar text stack your user interact with blockchain with wallets with bridges uh pay fees and uh all of this stuff and only after development you start marketing very uh expensive and endless process. But I don't want to touch marketing today because to start marketing you you should have an MVP or any uh yeah any product to advertise. So yeah uh let's go to development. When you start uh thinking about uh how do to develop a chain or product or D app, you always try to answer to the most uh common question and uh first one which blockchain I need to choose to launch a product. Uh all of you has a lot of option. You can go to traditional way with Ethereum, you can go with some risky way with Salana or if you like Kazins and you are crazy, you can go with Tron. And yes, that's your choice. uh when you make decision about blockchain after that you're going to uh thinking about UIX and how to build the UIX which uh will attract new people because the current solution it's not really attract uh web to audience for example my grandmother won't just send me 20 bucks to Christmas and uh she won't able and she don't want to figure out with crosschain bridges wallets and all other crypto stuff and uh yeah the main question how I can cover infrastructure when I get money to pay developers for it and uh I can try to answer the first question and maybe it's it will be close and solve all other problem uh yeah which blockchain to choose to launch a app you can go with Ethereum but you will you will face with too much competition because a lot of product already launched you can go to Salana and face to kind of expensive infrastructure with problem with scalability because you don't go you you cannot go to EVM to attract more user as already said if you're risky people and you you're crazy person you going go to Tron and or it's can be a custom solution you can create your own blockchain when you can set up a gas plan when you can choose a base token when you can do all what all what you want and uh yeah the main question now is uh how I can create my blockchain is Is it uh is it expensive or not? Is it how difficult? And uh yeah, we have two option to create a blockchain. First one, you can hire a team, you can run validators, node, you can uh yeah, find a team of developers who can do it, but you need a lot of money. Uh and unfortunately, I don't have 1 million with me and all our developers are busy on hackathon. And uh yeah we uh all that you have is uh second option is uh use virtual chain network solution and uh now we start entertainment part. If any one of you want to create a chain from from your laptop or mobile right now uh you can scan this QR code. It's absolutely free. You don't need to pay for anything. Yeah, you can do it from your phone and uh yeah, it's uh will be spent 10 10 minutes maybe 15 minutes and after after this slide you will uh go away with whole ecosystem on your phone on your chain with uh withdrawal function from Texas to your own blockchain with your own crosschain decks and uh a lot of other integration. So if you yeah already scan we can go or I need to wait. Okay, seems yeah already scan. Uh so yeah we start from set up the virtual chain and uh uh what does it mean virtual chain uh generally virtual chain is just a fork of Aurora but it's fully customizable to for your needs uh with gas token with uh gas plan with all all permission and uh yeah our our setup will start from permission if you want to create a defy chain with open access to everyone developer who want to deploy contract deploy token You can choose the public uh permission. If you want to launch FWA or gaming uh you should choose a uh oh yeah you can choose a permissioned version because uh you will have a white list for developers who can deploy contract to avoid the malicious contract and uh yeah to avoid the scam of your of your user and uh yeah after that the base token uh base token can be uh any what you want you can use aurora ethereum bitcoin or You can use a stable coin as a as a base token to uh to create like a bank experience when user don't need to have Ethereum or any other token to cover the fees. Uh user can pay fees in USDT and if he want to transfer money he just pay less than one cent on USDC and forget about any other fees and fees token. Uh and yeah my lovely feature is gas mechanics. Uh in your chain you decide who pay uh if you want to make you make the way for you for your user easiest uh you can just cover their expenses. For example, if someone from web two world come to you all all what he want is just to make transaction don't want to think about fees and token for it. So uh you can uh set up a custom gas plan when you can say okay for first five transaction per months will be free for user I will cover it after that uh he will yeah he will care about it and uh why it's good for example if you doing some telegram app you can uh invite people to your own blockchain it says guys uh it's five free transaction for you and after that you can monetize this audience through through the fee because all the fees which you collect will going to you. Uh and yeah just some me for marketing which represent our current market. Uh if you're a founder and you have $500 you can go to agency to pay them for our session. You can buy Telegram bots to to see uh every second message uh LP LPG go to market. Yeah. and or you can cover more than 100,000 transaction of a user and uh yeah build the best user experience for for them. Uh in this moment if you start creating your chain you just need to click uh deploy your chain and that's all your chain will be ready and uh after that uh yeah we reach the file of the first milestone it's your chain is already already launched. uh I totally understand and you will ask a question what I need to do with my chain because it's it's only blockchain it's not does it mean any product any value for user uh and it's no any ecosystem and uh yeah that's probably what we want to solve uh the integration if you launched with Aurora we already prepare for you uh four and or maybe already more uh ready made integration with which you can integrate free and automatically for example on ramp solution for your own blockchain. You can yeah uh integrate it in in uh one hour and uh your user will will have opportunity to top up uh your chain uh uh wallet via Mastercard or uh or Visa. Uh we also provide the oracle if you want to build a lending or staking or any financial product to to have a yeah token pair and uh any any price feed. Uh when you deploy your blockchain you instantly will have a block explorer to check all transaction and all uh yeah all activity. Uh we also provide integr integration to intense. It's a crosschain uh swap platform when you can access and uh it mean your your blockchain will have access to crosschain into swap with Bitcoin, Salana, Tron and other the most popular foring forcing chains including ZK Zcash and B chain or tone if you want to uh allocated some million hamster com your chain. Yeah, you can uh you can do it easily. And uh yeah, if you if you want to have a DEX on your blockchain, we can do it in one day just via request. You request a DEX and we deploy for you the uh Telaris. It's already it's dexes which already exist on Aurora but you will have the your own chain on uh on this deck and uh yeah at this point you spend uh $0 and if you start creating blockchain you already have four automatic integration 200 virtual chain in ecosystem uh 1,000 transaction free transaction for a user uh covered by our uh 14 blockchains you can make crosschain transaction with and uh you spend Yeah, zero for it. Uh if you don't uh if you don't have any integration uh already what you want, we we propose to use our marketplace with our with our partners. Yeah, our partners s propose to all our uh ecosystem the discount for any any services. For example, if you want to integrate the safe multisk, you can do it. Yeah. with discount price and without any other partners. Uh and yeah, that's question what I feel in the air. Uh yeah, I have blockchain, I have ecosystem, but I still don't understand why I need this and what's the use case for for a blockchain uh my own blockchain instead of use Ethereum, Polygon orbitum. uh it easy for example it's it's a gaming uh you you can already launch a game on telegram and uh you have a million uh yeah million audience but you cannot monetize it and uh if you want to make some revenue from this audience you can uh move there to the to your blockchain to earn uh a fees from them or if you're going with defi you can launch a launch pad for 200 uh virtual chain and uh you will yeah have user from the first Today uh if you want something built in RWA, you can use the in the near intent solution to crosschain swapping the RWA token and the shares. If you want go if you want going with the pin it's yeah also solution for you because you can sell compute or any other cloud services for your own token for on your own blockchain and uh yeah if you if you go to VCs and says they have a token they will ask about utility this is great utility what you can have it's a fe token in your blockchain and a lot of more different use cases and uh yeah some secret from me if you have any idea idea how to use a virtual chain or what to what to build uh on virtual chain. Today we have last day of uh applied uh for our incubator with near and leniscap. So after that uh you will have three months incubator uh with your virtual chain idea with top mentors and after that you can uh yeah you can go to ves with lemiscap and uh raise up to million to your startup. And uh yeah my favorite part I already give you the text tech and the solution but you you still have struggle to start something and yeah some insights and motivating to push you to start something uh today not tomorrow in 2024 or 5,000 project launch it but less than 1% build their own chain. Uh yeah maybe it's sign to start to change the game because how we see in the third point industrial create their own chains to onboard more audience and give them new opportunities it's base Sony and uh uh uni chain by unis swap and a lot of other example of company which already start create their own chain to onboard onboard users and propose them the custom solution and the uh to not be limited by Ethereum or any other chain uh setups and uh yeah less than 3% of Serbian population use a cryptocurrency uh if you can propose them and if you can deliver to them the uh something comfortable and uh really useful product uh you can earn the more than three million people just from Serbia because uh people here use fintech product but uh still has a struggle to start using crypto. And uh yeah, thank you Belgrade. I hope next year we will see the more boost of company who use virtual chain for their for their uh tips and uh yeah uh yeah my my name is Gregory. Yeah. Uh if you want to reach out me you can scan your code and uh ask any question and uh yeah invite me to raka beer or coffee and I live here and uh yeah if you have any any question I will happy to answer it. Yep. Hi, thanks. It's interesting tech. So, I was wondering uh how decentralized the infrastructure is because um I guess you mentioned you have 200 virtual uh chains now and how can you make sure it's like it can scale to like a thousand or even more and like where it's actually running like um like the you know where the validators are running where anyone can join as a validator. kind of or it's more like a like a closed system on some servers right now. >> Uh yeah, it's a good question. Uh we use the public RPC of near and near node. So when you create your chain, the the private key for this blockchain and uh yeah, all settings and uh all permission will transfer to you and after that it's yeah hosted on uh near node and uh yeah on public infrastructure. So the next one >> uh yeah question from me uh thanks for the presentation uh you mentioned your solution is good for telegram games right I'm curious uh do you have integration uh with telegram stars in order to buy like uh internal tokens by telegram stars >> uh not yet or yeah I also work on near intense and on near intense we start integrating tone and uh hopefully it will be announced next week maybe yeah maybe next month but uh Yeah, we still don't start to do something with Telegram because we don't support a ton. But yeah, all uh all things are changed and yeah, who know maybe yeah, at summer we will pro promote this feature. >> Okay, thanks. >> So yeah, I think thank you. Yeah, that's all.
