Dorothy: Interlayer for rollups |14th Oct 2023 | Sunway University | ETHKL 2023

and the in layer we're building uh we give it a name Beacon layer um is actually acting like a Marketplace for sequences so when you um initiate a transaction to the rollup the beacon layer will automatically help you assign this transaction to the users who are operating the sequences of course um how do you qualify as a user to run sequences for the rollups you like um you need to stake ethereum and other reaking assets um to qualify and you might get slashed if you have any wrongdoing that's why I said it's kind of like a PA chain Network where um there's value creation and capture in this network and also um the uses um are essentially acting like a Gatekeepers in this network they they stake assets they get assigned to uh basically run transactions order them and execute them and then they get staking rewards and after um the r the rollup transaction um is processed they also get verified through our building function um using wasm VM so uh besides um just processing the data we also provide an actual layer of of security by a verification um using wassom so um throughout the process there are actually um different tier of security or finality you can get when we press or order the data other the transactions through the sequences we will call them soft final um I don't know if you guys have ever um made a transaction on Unis swap um on arbitrum for instance when you swap um e into tther on uh arbitrum um your order um has not been sent to the main net or the underlying chain which is ethereum in your case so you are only arriving at soft finality which means um your your data has not been final approved by by the whole network and it's eum does not recognize the legitimacy of your transaction but normally as a user or as a Trader we don't really care as long as arbitrum tells us our our transaction is final we see it as final that's why we call this s final so um what interlayer or Beacon chain provides in addition to that self finality is a verification level finality that's through the building function we just mentioned in wome that would allow you to get a higher level of security after you make that transaction on Unis swap so instead of um instead of saying oh my mamas has confirmed my transaction now you can say oh the beacon layer has confirmed my transaction and since the beacon layer is run by a decentralized group of users um and they run uh the sequences and process my data so I can roughly believe that my transactions are really final and secure and then we have the hard finality which is when the transactions are actually sent to the base layer in ethereum in this case and that and normally with optimistic roll up you have 7day waiting period it's until the 7day wait period is over and then you can call the transactions are final that's that's when the transaction is confirmed by everyone in the universe so um I do have a question for you guys just in case you fall into asleep um when you when you bridge an asset um using Orbiter Finance or I don't know um caness or any other Bridge um after you see ma must shows confirm that your um your bridging transaction is through like what level of finality have you arrived wow you guys are so smart you're you're the first audience that get this question right you should be really proud of yourself thank you so so what all layer is providing the inter layer is adding an extra layer of security to that self finality so you can say you have arrived at verification level security that could mean defi protocols and other um other protocols can utilize this functionality to enable cross rer messaging and the transfers um and also um The Bean chain or the inter layer would enable um upgrades without hwks which is also an important functionality for uh Builders um you don't want to always H Fork your chain whenever you have an upgrade that's something a lot of existing rollup technology does not provide and we proud proudly support forless upgrade so um before I end this um sharing um I would like to also um show you guys what we also provide is rollup as a service so as I mentioned uh we provide in layer for rollups but if you do not have an existing rollup and you want to build one for your app then we also help you spin up rollups within two minutes using our standardized platform and SD case um so these are all the components you can basically customize for your own chain um for instance you can uh you can choose what sequencer Network you want to use uh what rollup stack you want to use as everyone know op stack arbitrum orbit polygon cdk and stock Weare all these um rollup Stacks are pretty normal nowadays so you can freely choose whichever rollup stack you want to use for your own rollup and also you can choose to customize your da whether you want to use sashia igen da or Avil it's all free for you to choose and we also um have partnership with a lot of the bridging um projects so you can freely choose whichever Bridge you want to use um and underlying chain uh besides ethereum you can also SLE your transactions on say opnb or polygon or polygon ZK evm chain it's all up to you um and of course you can customize your gas on your rollup whether you want to make your own token as a gas token whether you want to make it gas- free like a a gasless experience in a game um everything is customizable so um if you're building a game um a social network or a defi protocol that actually require very high performance high security and food decentralization you can uh comment to us we can help you that's all thank you thank you very much DY for the lovely presentation all right oh wait hold on Dy we'll see whether they have any questions or not uh lovely presentation I learned a little bit more about soft finality and heart finality but I think you're right to the user experience heart finality doesn't really matter we just if arbitrum says it's done it's done L um okay can we open it to the audience does anybody have a question pleas raise your hand and then we'll pass you a microphone anybody has anything to ask the way she's describing all like you have solved all problems in the whole world of blockchain gasless also can fogless also can this one also can wow amazing any questions if not we okay you got one over here uh can we pass a mic to him our our volunteers will come and hand you a mic please introduce your name as well as your question to Dorothy you hi I'm Keith just a question how can we use how can we test out later um there there are a few ways um the first way is to go to our website actually I think it's um it's here um dashboard. od. technology or you can just um go to our website .io and then you can find the rollup launch pad where you can just play around with our platform you can uh basically uh choose whatever tier you want to use you can start with the free trial and the the chain will automatically terminate itself in two hours so there's no waste of resources you can spin up as many rollups as you want at the same time and you can choose the guest model Etc um so if you are looking to um test um the rollup with more functionality or more customization then you can reach out to our team um through email Twitter um TG what whatever or you can speak to one how Who's Next to You RBD yeah so um yeah I think um that these are the two main ways you can test our product um of course we also have um um some other um projects that are working with us there are um a few gaming projects that are um launching using our um roap stack especially for fully Unchained game we have built a specific um roll of framework called turbo which would allow gasless transaction s burner wallet and like horizontal um scaling which means we can spin up um 100 rollups at the same time which serve as gaming server um so instead of squeezing everyone into one rollup now Gamers can choose with Trav rollup they want to use to play the game more similar to a weather with blade out and another project called cellular you can play these games um through our platform um you can check out other information on Galaxy thank you excellent very comprehensive answer and I like that your website has a very nice uh dashboard that you can easily test out your rollups okay anyone else want to ask a question you got one here in the front we'll get a volunteer got okay got two one here in the front then the lady at the back okay uh volunteers will come and pass you your mic please introduce your name and your question thank you H dthy thank you for your D on your talk my name is ISO I would like to to ask you what is the benefit uh for a layer to provide such uh good service basically what is your business model yeah so so the business models is actually um in the inter layer we just [Music] mentioned so so our vision is that um in the in the foreseeable future we'll have um a lot of infrastructure in the industry will not be able to accommodate a million users not even 100K uses um so by um owning the block space to your and also customize the chain in the way they want and also um through the powerful um BM and other um VM um technology we can support um projects to uh basically service millions of users at the same time especially for gaming projects I think um it's inevitable that they would have have to use this horizontal scaling solution to service millions of users at the same time so um to support this Vision all all these rollups will need um a decentralized network to run sequences and validators because um the the cost to run its own validator network is quite high and also their the gaming project or the uh social network project team are not expert to run decentralized network run into security issues like running chain and other projects so um this network would um help projects to um basically forget about all the overhead and all the devop they need to um spend energy and uh money in to solve all these problem they can simply um just use a resolution and it's a decentralized network so we'll have a token um and users will be able to stake ethereum and our own token to support this network so so to promote this decentralized network of course we need to work with as many projects as possible and providing R service is another way to um lure them into our ecosystem thank you all right uh last question was at the back uh leading in green thank you very much hi Dorothy um thank you for the presentation um my name is Shannon and I'm from coin Geo I just have a quick question on the the aggregator yeah um Step that you mentioned just now so just wondering if um the aggre aggregator function does it work like a ZK Road up and if yes um would you say it's easier for project who is using ZK Road up um to on board to this a biger layer that you're offering yeah so um this framework is actually um um execution model agnostic so so you have aggregator that's basically aggregating orders it doesn't really matter what um execution model you choose um so uh we we do support um optimistic rollup in our own test St right now but we kind of took a hybrid approach where you basically process all the data in an optimistic way and then whenever there's a challenge we use DK Pro to prove the transaction so it reduces the cost and the uh overhead tremendously but um overall this int layer Network um wouldn't wouldn't be like a execution model um specific we can support both DK and uh op Stacks all right thank you thank you thank you for the question great questions and great answers let's give Dorothy a big big round of applause thank you very much
