\n\n# Getting Started\n\n**1.** BUILDers should submit their BUIDL projects via https://dorahacks.io/hackathon/39/. But before that, make sure that you already have an account.\n\nUse the **Sign in/up button** at the upper right corner of the page to access the sign-up options.\n\n

\n\n**Github, crypto wallet** and **email** are supported for creating an account. For BUIDLers, we recommend you to connect the account to your **github** to make more people know what you are building at any time.\n\n*You may be asked to receive a verification code via email. The email may take some time to arrive. No worries! The code will not expire in 10 minutes when you click “send code”.\n\n**2.** Before the submission of DDL on October 10, please make sure you have added your Github link to the project. You can submit the project first, edit it later before the DDL.\n\n**Click “Submit BUIDL”.**\n\n

\n\n**→ If you already have a BUIDL on DoraHacks**\n\nChoose your BUIDL project from **\"Apply with Existing BUIDL\"** and identify the track you want to join.\n\n

\n\n**→ If you want to submit a new BUIDL**\n\nBefore submitting, you need to create a BUIDL project. Click **“Create a new BUIDL”** and fill in the form as required. You'll be directed to \"Apply for PermaDAO Web3Infra Hackathon\" page after the new BUIDL setup.\n\n

\n\nNote that for demo, demo link and social media, please offer **URLs (with http/https://)**.\n\n

\n\nDon't forget to check \"I agree to the User Agreement\".\n\n

\n\nBack to Application window. Choose your BUIDL project from **\"Apply with Existing BUIDL\"** and identify the track you want to join.\n\n**3. When submission succeeds, you'll see this notification.**\n\n

\n\n# Project Verification\n\nWait! Don't just leave your BUIDL here and forget about it. Please contact DoraHacks staff on **Telegram** [@dorahacksofficial](https://t.me/dorahacksofficial) for project verification and promotional support. We'll make every BUIDL a poster and arrange a live project demo session for you via Youtube Live/Binance Live. Don't let go of the chance to receive huge visibility!\n\nOr, you can also reach us out at the **#buidl-verification channel** in the **Discord** [https://discord.gg/PCdeK2nfwh](https://discord.gg/PCdeK2nfwh)\n\n# Want to make some changes to your BUIDL?\n\nYou can edit any details of your project in **“My Profile-edit”**, including project description, team members, tracks and bounties, etc..\n\n

A variety of storage-related products can be developed based on Arseeding developed by everFinance. Users can experience a convenient storage service via Web3infra. Developers are welcome to make upgrades and innovations on the basis of existing demos, without theme limitation. \n\nAs the Web3Infura hackathon is designed to engage products and front-end developers in our application building, there is no barrier for web2 developers.\n\nRefer to the demo below as an example: https://demo.web3infra.dev\n\n# Dates and Timing\n- **Announcement**： September 2th\n- **Projects Submission**: September 8th - October 10th\n- **Community Voting**: October 21st - October 23th\n- **Judge Voting**: October 30th\n- **Final Result Announcement**: October 31st\n\n# Prizes\n- **First Place**: 500 AR + 3000 U equivalent token package\n- **Second Place**: 300 AR + 1800 U equivalent token package\n- **Third Place**: 100 AR + 600 U equivalent token package\n- **Community Special**: 1200 U equivalent token package *3, directly set and selected by our sponsors.\n\np.s. The price fluctuation of each sponsor’ s token is subject to the price on the date when the host receives the transfer.\n\n# Rules\n- Build a permanent storage application based on web3infra.dev service, which can be a decentralized web drive, decentralized NFT storage service, decentralized chatting tool, decentralized document backup tool, etc.\n- Refer to the demo below as an example: https://demo.web3infra.dev\n- Use the storage service web3infra.dev to develop application\n- There is no restrictions on the type of \"application\"\n- The App must support metamask login and be compatible with mobile wallet login. Support for arweave wallets at the same time is desirable.\n\n# Judges\n\n

\n\n\n# Grading Criteria\n\n### Judge:\n
\nSubmissions of tracks will be judged by technical team representatives based on their technical merits as well as the likelihood of implementation.\n\nSubmissions of sponsored bounties will be judged by sponsors’ technical team with representatives appointed by the sponsors of individual bounties.\n
\n\n### Community Vote：\n
\nThe community‘s vote will account for 10% of the final result. Before the community votes, PermaDAO will give out 100 AR in the Discord channel, and everyone in the community is eligible to claim the Tips.\nCommunity members are free to tip their favorite project later. Each person has one vote, and the Tip has to be more than 0.1 AR.\n\n# Developer resources\n- web3Infra Doc：https://web3infra.dev/\n- arseeding repo：https://github.com/everFinance/arseeding\n- hackathon rules：https://github.com/everFinance/web3infra-hackathon\n- For more information: https://discord.com/invite/kYrAx69Dxu\n\n\n# About PermaDAO：\n\nHave you heard of Alexandria’s library? Well, Arweave will be our Alexandria’s Library in this beautiful Web 3.0 era. Permanently storing human history is extremely important to mankind. Now that Web3.0 is in full swing, Arweave will be seeing more and more developers use its infrastructure. This will create a a more unified ecosystem for us all. \n\nPermaDAO is a community of co-builders created for one purpose: to contribute to the Arweave ecosystem. Anyone and everyone can find their way in order to contribute to the ecosystem, any proposals or tasks involving anything arweave based can be posted here which will then be supported by the whole community. Keep in mind that Web2 is quickly shifting over to Web3 and with the power of this community we’ll surely leave a footprint behind, together.","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":35,"winnerAnnounced":false,"teamCount":0,"title":"PermaDAO Web3Infra Hackathon","uname":"arweave2022","imageUrl":"https://cdn.dorahacks.io/static/files/Web3Infra_banner_1.jpg","originUrl":null,"startTime":1662609600,"endTime":1665417600,"timezone":"UTC","city":"Virtual","visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":20000,"bonusMechanism":"XX","followersCount":0,"ecosystem":null,"applyGuide":"https://dorahacks.io/blog/guides/permadao-web3infra-hackathon/","weight":0,"participationForm":"Virtual","field":"","email":null,"contacts":null,"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,"isMultiTracksAllowed":false,"tracksLimitForBuidl":0,"showIdeaTab":true,"showQuestionTab":true,"showTeamTab":false,"bonusDescription":[],"askHackers":[],"isEnabledQuestions":false,"isEnabledAskHackers":false,"isBuidlsPrivate":false,"trackJudgingMaxScore":100,"bountyJudgingMaxScore":100,"isExtended":false,"oldEndTime":null,"status":2},"status":4,"bounty":null,"track":null,"table":"0","trackObj":null,"bountyObjs":[]}],"chain":["Polygon","IPFS","Ethereum","Solana","Arweave"],"chainList":["Polygon","IPFS","Ethereum","Solana","Arweave"],"appliedGrant":false,"acceptRewards":false,"owner":48775,"ownerInfo":{"nickname":"airyland","username":"airyland","avatar":"https://cdn.dorahacks.io/static/files/18e01a50f282a27a658eaaa4c86b992b.jpeg"},"visible":true,"deleted":false,"continuousSponsoring":false,"pageView":0,"sponsoredCount":0,"starCount":0,"sponsoredAmount":"0.00","sponsoredPersons":0,"followers":1,"voteCount":0,"projectMembers":[{"id":2541,"member":{"id":48776,"username":"U_48776","avatarUrl":"https://cdn.dorahacks.io/static/files/18e01a51400aee6b65c164b46068500c.jpeg","nickName":"0xjoanne"},"email":"***@***","status":"accepted","role":2,"title":null,"introduction":null}],"bnbRound":null,"doraGrantDaoTags":[],"techTrees":[0],"infrastructureTags":[0,2,5,7,8],"otherInfrastructures":[],"lastEditor":{"id":48775,"username":"airyland","date":1665469934000},"upvoted":false,"followed":false,"upvoters":{"count":0,"list":[]},"kycStatus":0,"ideas":[],"name":"ECHO","techniqueField":"Infrastructure,permaweb,web3 social","source":"独立开发","vision":"The first decentralized engagement plugin based on Arweave.
