The ecosystem has more than 1,500 active dApps across multiple categories such as DeFi, Metaverse, blockchain games, NFT, and more.\n\n# Developer resources\n\n- https://bnbchain.org/en/developers \n\n- https://t.me/BNBChainDevs \n\n- https://twitter.com/BNBCHAIN ","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":254,"winnerAnnounced":false,"teamCount":0,"title":"BNB Chain Hackvolution: Empowering next-gen dApps with opBNB and BNB Greenfield","uname":"hackvolution","imageUrl":"https://cdn.dorahacks.io/static/files/1899199dfa82761aff8073b488fa7949.jpg","originUrl":null,"startTime":1689253200,"endTime":1693929599,"timezone":"UTC","city":"Virtual","visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":79000,"bonusMechanism":"xxx","followersCount":0,"ecosystem":null,"applyGuide":null,"weight":0,"participationForm":"Virtual","field":"","email":null,"contacts":null,"externalContacts":null,"telegram":null,"discord":null,"whatsapp":null,"wechat":null,"prizeFundingEscrowed":0,"token":"USDT","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":{"id":286,"name":"Infra","judgingCriteria":"","weight":0},"bountyObjs":[]}],"chain":[],"chainList":[],"appliedGrant":false,"acceptRewards":false,"owner":46202,"ownerInfo":{"nickname":"taijusanagi","username":"taijusaangi","avatar":"https://cdn.dorahacks.io/static/files/18e0187ccf95ec05cad4b2a41829966a.png"},"visible":true,"deleted":false,"continuousSponsoring":false,"pageView":0,"sponsoredCount":0,"starCount":0,"sponsoredAmount":"0.00","sponsoredPersons":0,"followers":0,"voteCount":0,"projectMembers":[{"id":6215,"member":{"id":95212,"username":"U_44aefb7193894b","avatarUrl":"https://cdn.dorahacks.io/images/hacker-avatar/3.jpg","nickName":"hacker2ac0c02"},"email":"***@***","status":"pending","role":3,"title":null,"introduction":null},{"id":6208,"member":{"id":96207,"username":"U_c981f1cb862888","avatarUrl":"https://cdn.dorahacks.io/static/files/18e008ec59df25a31ea0bac4573aa5f2.png","nickName":"Praiseudah"},"email":"***@***","status":"pending","role":3,"title":null,"introduction":null}],"bnbRound":null,"doraGrantDaoTags":[],"techTrees":[0],"infrastructureTags":[1,8,70,76,81],"otherInfrastructures":["category:Storage","infra:opBNB","infra:Greenfield"],"lastEditor":{"id":46202,"username":"taijusaangi","date":1693565287000},"upvoted":false,"followed":false,"upvoters":{"count":0,"list":[]},"kycStatus":0,"ideas":[],"name":"GreenGate","techniqueField":"","source":"Hackathon-BNB Chain Hackvolution","vision":"GreenGate is a data migration service designed primarily to transition data to the BNB Greenfield storage system.
