Linux and MacOS are recommended as Windows is still in testing. Keep in mind that **we do not yet have a devnet, testnet, mainnet, or token.** Your project should be a locally run web 3 application! \n\n**What to Submit**\n\n- The project must be open-source and have a URL to a public code repository.\n- Videos must be uploaded to YouTube, Vimeo, or Facebook Video and made public.\n- The completed submission form on Dorhacks before the deadline.\n- Please see the [Official Rules](https://dorahacks.io/hackathon/lineradeveloperschoolautumn2023/official-rules) for full details.\n\n# Judging Criteria\n\n- **Technological Implementation**
Does the interaction with the Linera SDK demonstrate quality software development?\n\n- **Design**
Is the user experience and design of the project well thought out?\n\n- **Potential Impact**
How big of an impact could the project have on the Linera ecosystem?\n\n- **Quality of the Idea**
How creative and unique is the project?\n\n# About Linera\n\nInitially inspired by the low-latency payment protocol FastPay developed at Meta, Linera is a layer-1 blockchain protocol designed to bring the elastic scaling of web2 to web3.\n\nLinera introduces the idea of operating many lightweight chains, called microchains, in parallel in the same set of validators. Microchains communicate instantly using the internal network of each validator. Compared to traditional multi-chain systems, a benefit of running all the microchains in the same set of validators is that creating chains does not impact the security model.\n\nIn Linera, a validator is an elastic web2-like service that validates and executes all the chains. We call this the integrated multi-chain approach. The number of microchains present in the Linera system is theoretically unlimited. This is possible because only the chains being actively extended with new blocks require work from validators. Linera encourages validators to use data centers or cloud infrastructure to unlock elastic scaling and benefit from standard production environments.\n\nTo ensure decentralization, the Linera protocol uses proof-of-stake mechanisms together with scalable auditing procedures. Each microchain can also be separately executed on commodity hardware. This allows the network to be audited by the community in a distributed way to ensure full accountability of validators. \n\nThe aim is to make it as easy as possible for developers to build on Linera. The programming model of Linera does not depend on a specific programming language. We are using WebAssembly (Wasm) and Rust for the initial execution layer of Linera.\n\n**At present, Linera does not yet have a devnet, testnet, mainnet, or token.** \n\nBy making multi-chain programming fast and scalable, we believe that a paradigm shift comparable to the evolution of databases from SQL to NoSQL is necessary for future decentralized systems to provide low-latency guarantees at arbitrary scale. We are excited to see how developers take advantage of this unique architecture and performance capabilities.\n\nLearn more about the project and architecture:\n- [linera.io/overview](https://linera.io/overview)\n- [linera.io/whitepaper](https://linera.io/whitepaper)","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":175,"title":"Linera Autumn Developer School 2023 | Rust, WASM, Linera SDK","uname":"linera-autumn-2023","imageUrl":"https://cdn.dorahacks.io/static/files/189f9de5200e2147ce189144b5584b7f.jpg","originUrl":null,"startTime":1694156400,"endTime":1697439600,"timezone":"-120","city":null,"visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":12500,"bonusMechanism":null,"followersCount":0,"ecosystem":"Linera","applyGuide":null,"weight":30,"participationForm":"Virtual","field":"Blockchain","email":"jesse.pariselli@linera.io","contacts":"Telegram,@jessep461","externalContacts":null,"telegram":null,"discord":null,"whatsapp":null,"wechat":null,"prizeFundingEscrowed":0,"token":"USD","prizeSafeForm":0,"prizeSafeNetwork":null,"prizeSafeOwner":null,"prizeSafeWallet":null,"prizeSafePublishDate":null,"hasOnboarding":false,"isPublicTrackJudging":false,"isEndedTrackJudging":false,"question":null,"countryId":null,"cityId":null,"venueName":null,"venueAddress":null,"category":0,"isEnableBounty":true,"isBountyRequired":false,"isEndedBountyJudging":false,"bountiesLimitForBuidl":10,"isPublicBountyJudging":false,"status":2},"status":4,"bounty":null,"track":null,"table":"0","trackObj":null,"bountyObjs":[]}],"chain":[],"chainList":[],"appliedGrant":false,"acceptRewards":false,"owner":99283,"ownerInfo":{"nickname":"ashu26jha","username":"U_297f3c91ce8181","avatar":"https://cdn.dorahacks.io/static/files/18e00ab33f78760ac1a3438460cb9a32.jpeg"},"visible":true,"deleted":false,"continuousSponsoring":false,"pageView":0,"sponsoredCount":0,"starCount":0,"sponsoredAmount":"0.00","sponsoredPersons":0,"followers":0,"voteCount":0,"projectMembers":[{"id":6768,"member":{"id":99711,"username":"U_5ce75e2c7c86e9","avatarUrl":"https://cdn.dorahacks.io/images/hacker-avatar/2.jpg","nickName":"Anuj Rajput"},"email":"***@***","status":"accepted","role":2,"title":null,"introduction":null}],"bnbRound":null,"doraGrantDaoTags":[],"techTrees":[0],"infrastructureTags":[70,71],"otherInfrastructures":["category:Linera"],"lastEditor":{"id":99283,"username":"U_297f3c91ce8181","date":1697431139000},"upvoted":false,"followed":false,"upvoters":{"count":0,"list":[]},"kycStatus":0,"ideas":[],"name":"Li-NFT","techniqueField":"","source":"-","vision":"NFT-Fi dAPP on Linera","projectDescription":"Introducing NFT-Fi on the Linera network, where we've build the NFT contract from scratch with `ERC-721` standards in mind.\n\nMint, Sell, and Chat\n\nCreate unique NFTs with a single prompt, mint the ones you love, and sell them on our marketplace to earn real rewards.
