Each track is designed to push the boundaries of innovation.\n\nWhether you are a newcomer to the blockchain space or an experienced developer, we have designed these tracks to challenge, inspire, and uplift your skills. Each track has its own specific focus, but all aim to encourage you to explore, innovate, and create real-world solutions harnessing blockchain technology.\n\nBelow you will information on all tracks provided by BNB Chain, Space ID and Polyhedra!\n\n**BNB Chain Tracks**\n\n1 - BNB Smart Chain for all ( infra/dapp wishlist of bsc);\n\n2 - Powering Next-gen dAppson opBNB ( infra/dapp wishlist of opBNB);\n\n3 - New Data Economy on Greenfield( infra/dapp wishlist of Greenfield.)\n\nhttps://github.com/bnb-chain/community-contributions/tree/main\n\nSupporting info: Please view our wishlist for more information on topics [https://github.com/bnb-chain/community-contributions](https://github.com/bnb-chain/community-contributions?ref=bnbchain.ghost.io)\n\n**Space ID Track**\n\nName: Novel Use Cases for SPACE ID Domains\n\nDescription: Interesting projects integrating SPACE ID, or projects that explore innovative ideas using SPACE ID. Potential ideas include but are not limited to cross-chain resolution, decentralized messaging, new types of resolvers, and account management systems.\n\nResources:\n\nHackers can use the following resources to learn about SPACE ID:\n\n1 - SPACE ID SDK Documentation\n\nhttps://docs.space.id/developer-guide/web3-name-sdk/sid-sdk\n\n2 - EIP 3668 - Secure Offchain Data Retrieval\n\nhttps://eips.ethereum.org/EIPS/eip-3668\n\n3 - SPACE ID Tutorials\n\nhttps://docs.space.id/getting-started/tutorials\n\n**Polyhedra Track**\n\nName: Decentrailsed ID\n\nDescription:\n\nopBNB provides a great solution for widespread adoption across multiple digital environments such as games, social networks, the metaverse, and high-frequency trading.\n\n[zkBridge](https://zkbridge.com/?ref=bnbchain.ghost.io) provides the most secure design for general message passing and asset bridging between various L1 and L2 networks. The end-to-end system for zkBridge fast finality on opBNB ([https://zkbridge.com/opbnb](https://zkbridge.com/opbnb?ref=bnbchain.ghost.io))offers a smooth cross-chain user experience with the high-security and low-latency zkBridge on opBNB.\n\nIn our track, we will instruct you to build on opBNB and explore the use case of zkBridge on opBNB.Resources:[https://zkbridge.com/](https://zkbridge.com/?ref=bnbchain.ghost.io)\n\n**Task 1:**\n\nIn this scenario, we have a computational task denoted as 'f' that accepts an input 'x' and produces an output 'y'. Below, you'll find the interface for this computation task, as defined in Solidity:\n\n```solidity\n\n// SPDX-License-Identifier: MIT\n\npragma solidity ^0.8.0;\n\ninterface ComputationTask {\n\n// This function carries out the computation task.\n\n// It takes an input parameter 'x' and returns an output 'y'.\n\nfunction compute(uint256 x) external returns (uint256 y);\n\n}\n\n```\n\nOn opBNB, the computation is executed optimistically, meaning there's no assurance that the computation will be performed correctly within the stipulated challenge period. To address this, we've introduced a committee responsible for executing the computation accurately. Committee members are required to provide their signature only if they confirm that the output 'y' is correct.\n\nHowever, some committee members may exhibit laziness, choosing not to rigorously verify the computation. These \"lazy\" members might opt to request other committee members to supply the correct 'y' and then simply affix their signatures to it. Alternatively, they may blindly endorse whatever output obBNB generates.\n\nYour task is to devise a mechanism capable of identifying and flagging these lazy committee members.\n\n**Task 2:**\n\nComputation on the L1 Blockchain is excessively costly. For instance, consider the following computationally expensive task:\n\n```solidity\n\n// SPDX-License-Identifier: MIT\n\npragma solidity ^0.8.0;\n\ninterface ComputationTask {\n\n// This function performs the computation task.\n\n// It takes an input parameter 'x' and returns an output 'y'.\n\nfunction compute(uint256 x) external returns (uint256 y);\n\n}\n\n```\n\nExecuting the `compute(x)` function incurs a gas cost of approximately 1,000,000 gas.\n\nThankfully, opBNB provides a much more cost-effective platform for conducting such computations. Your objective is to delegate the computation from BSC to opBNB and then transfer the final result back to BSC via the Polyhedra Bridge.\n\nIt's worth noting that you can assume the client will request this computation every 10 seconds, offering the opportunity to batch transfer computation results to further reduce the cost.\n\n**Task 3:**\n\nOn-chain random numbers are crucial for gaming applications. We deployed a verifiable random function on opBNB, and it’s now waiting for applications to use it. We provides following off-chain RPC calls and on-chain verification method:\n\n1 - RPC:\n\n 1 - Register a service:\n\nVRFKey = await rpcCall(\"register\");\n\nIt provides you a VRFKey that can be used in verifying the random number.\n\n2 - Get randomness:\n\nrandomness, proof = await rpcCall(\"register\");\n\n3 - On-chain\n\n 1 - Register a service:\n\n```solidity\n\n// SPDX-License-Identifier: MIT\n\npragma solidity ^0.8.0;\n\ninterface VRF {\n\n// This function performs the computation task.\n\n// It takes an input parameter 'x' and returns an output 'y'.\n\nfunction register(address applicationAddress, uint256 VRFKey) external returns (bool result);\n\n}\n\n```\n\nThis function associates your VRF key with your dApp.\n\n1 - Verify:\n\n```solidity\n\n// SPDX-License-Identifier: MIT\n\npragma solidity ^0.8.0;\n\ninterface VRF {\n\n// This function performs the computation task.\n\n// It takes an input parameter 'x' and returns an output 'y'.\n\nfunction verify(address applicationAddress, uint256 randomness, uint256 proof) external returns (bool result);\n\n}\n\n```\n\nThis verifies the randomness is correctly generated against the proof.\n\nYou are allowed to freely use these interfaces. Now it’s your time to develop a fantastic application.\n\n**Open Campus Track**\n\nName: Decentrailsed ID\n\nDescription: Develop a decentralized identity system on opBNB. Utilize its infrastructure to implement on-chain reputation scoring and DID credentials verification. Focus on leveraging DID for transparent and secure identity management and authentication, eliminating intermediaries and prioritizing data privacy.\n\nGoals:\n\n- New applications using DID beyond existing use cases\n- Privacy focused on-chain credential and ID verification\n- Accessible UX for the masses\n- Reputation based scoring using DID"},{"id":479,"name":"Key Dates","slug":"key-dates","description":"

We invite you to participate in the BNB Chain Hackathon, Istanbul, taking place from November 10th to November 12th, 2023. This three-day event promises to be an exciting opportunity to explore the limitless possibilities of blockchain technology.\n\n# Event Details\n\n- Date: November 10-12, 2023 (3 Days)\n- Location: ESA Espor Arena, *Maslak, 42 Maslak AVM, Ahi Evran Cd. No:6/70 Kat:3, 34485 Sarıyer/İstanbul, Türkiye*\n- [Register Now](https://lu.ma/hackistanbul?ref=bnbchain.ghost.io)!\n\n# About the Hackathon\n\nFor this hackathon, we're thrilled to introduce you to opBNB and Greenfield, two cutting-edge blockchain platforms that offer endless possibilities for developers and entrepreneurs.\n\nBNB Greenfield provides decentralized storage infrastructure within the broader BNB Chain ecosystem. The idea is to help users and dApps to create, store, and exchange data with full ownership, and form a new data economy.\n\nThe opBNB network is the Layer 2 scaling solution for the BNB Smart Chain, powered by the bedrock version of Optimism OP Stack. It allows users to deposit and withdraw funds, use smart contracts, and view network data with high throughput and low fees, all while scaling beyond the constraints of the BNB Smart Chain.\n\n# Hackathon Requirements\n\nWe encourage you to develop in line with our Wishlist, which includes exciting tracks in both Greenfield and opBNB. Each track offers exciting challenges and opportunities for innovation. You can view the details list at the bottom of this announcement.\n\n# Rewards\n\nWe're offering up to $100k in rewards for your hard work and innovation:\n\n- 1st Prize: $15k\n- 2nd Prize: $10k\n- 3rd Prize: $5k\n\nPlus, up to 70k in addition rewards across a variety of categories!\n\n# The Rules of the Competition\n\nPlease read and follow the competition rules to ensure a fair and enjoyable experience for all participants. These rules cover eligibility, participation requests, and conduct during the event.\n\n**Submission Requirements**\n\n- Work must be deployed on or connected to GF/opBNB in some way.\n- Work that is open source and free for others to use.\n- Shared artifacts (GitHub, planning documents, and a short video).\n- Ensure the contract address has at least 2 successful transactions within the hackathon timeframe.\n- Tweet describing your project and tag #buildonBNBChain\n- For this hackathon, the project must be a new development in order to ensure equal opportunity\n\nPlease note that you do not need to pitch your idea to us. All we need is your submission.\n\nProjects will be evaluated based on 1) functional prototype highlighting a solution, 2) creativity, 3) readiness of the dApp and 4) usability.\n\n# The Spirit of the Competition\n\nRemember, hackathons are about learning, collaborating, and having fun. While some aim to win, most are here to explore new ideas. Keep the hacker spirit alive by working with other teams, mentoring newcomers, and enjoying yourself.\n\nJoin us in Istanbul for the BNB Chain Hackathon Istanbul, where innovation knows no bounds, and the future of blockchain technology is in your hands. Together, let's push the boundaries of what's possible and shape the future of finance and data management.\n\nFor more details, view the full rules of the competition at the bottom of this article.\n\n[Register now](https://lu.ma/hackistanbul?ref=bnbchain.ghost.io) and see you at the hackathon!\n\n\n# Competition Rules - Further details\n\n**1.** Eligibility:\n\nTeam Size:Teams may have a maximum of 5 hackers.\n\n**2.** Participants Requests:\n\nHackers who have been accepted to compete on a team must not be event staff, volunteers, mentors, judges, sponsors, or anyone else with special access to the competition.\n\nParticipants, including organizers, volunteers, and sponsors, are available to offer teams guidance and assistance.\n\n**3.** The hackathon is the only place where work can be done on a project.\n\n**4.** Groups are allowed to implement a strategy they developed in advance of the competition.\n\n**5.** Teams have the option of focusing on already completed ideas. There is no requirement for \"innovation\" in hacks. Anyone is welcome to contribute to a shared idea, and their work will be evaluated based on how well it is \"hacked.\" (It's unusual to come across something wholly novel these days, and teams often aren't aware if they're recycling a concept.)\n\n**6.** Groups are free to include third-party resources, such as code repositories, into their work. It is against the spirit of the guidelines to work on a project ahead of time and open-source it with the sole intention of using the code during the event.\n\n**7.** It is acceptable to include additional functionality into ongoing projects. Winners will be determined solely based on the value of any new features or functionalities introduced during the hackathon.\n\n**8.** When the clock runs out, teams must cease their hacking activities. After the allotted time has passed, however, teams are free to debug and make minor adjustments to their applications. e.g. It's acceptable to fix a bug that prevents you from demonstrating your hack if doing so involves adding only a few lines of code. You are not permitted to make any major alterations or introduce any new functionality.\n\n**9.** Teams can be disqualified from the competition at the organizers' discretion. Reasons might include but are not limited to breaking the Competition Rules, breaking the Code of Conduct, or other unsporting behaviour.\n\n# Follow us to stay updated on everything BNB Chain\n\n[Website](https://www.bnbchain.org/en?ref=binance.ghost.io) | [Twitter](https://twitter.com/BNBCHAIN?ref=binance.ghost.io) | [Telegram](https://t.me/bnbchain?ref=binance.ghost.io) | [Facebook](https://www.facebook.com/profile.php?id=61550857610291) | [dApp Store](https://dappbay.bnbchain.org/?ref=binance.ghost.io) | [YouTube](https://www.youtube.com/@BNBChainOfficial?ref=binance.ghost.io) | [Discord](https://discord.gg/bnbchain?ref=binance.ghost.io) | [LinkedIn](https://www.linkedin.com/company/bnbchaininnovation/?ref=binance.ghost.io) | [Build N' Build Forum](https://www.buildnbuild.dev/?ref=binance.ghost.io)\n\n# Developer Resources\n\nTakeaways of opBNB and BNB Greenfield to help you build:\n\n**1.** BSC Faucet: \n\n- https://testnet.bnbchain.org/faucet-smart/ \n\n**2.** opBNB:\n\n- Documents: https://docs.bnbchain.org/opbnb-docs/docs/intro \n\n- Bridge: https://opbnb-testnet-bridge.bnbchain.org/deposit \n\n- Explorer: https://opbnb-testnet.bscscan.com / , https://opbnbscan.com/tx \n\n**3.** Greenfield:\n\n- Documents: https://docs.bnbchain.org/greenfield-docs/docs/guide/home \n\n- Bridge: https://greenfield.bnbchain.org/en/bridge?type=transfer-in \n\n- Explorer : https://greenfieldscan.com \n\n- UI dApp: https://dcellar.io/","onboardingCompleted":false,"registerFormUrl":null,"preRegisterTime":0,"publicContactHackerHandle":null,"hackersCount":4,"title":"BNB Chain Istanbul Hackathon","uname":"bnbistanbul","imageUrl":"https://cdn.dorahacks.io/static/files/18bc1908027909f7bbd9fa540d38f3c3.jpg","originUrl":null,"startTime":1699772400,"endTime":1699815600,"timezone":"-480","city":null,"visible":true,"approvalStatus":6,"state":0,"voteUrl":null,"voteMechanism":null,"bonusPrice":100000,"bonusMechanism":null,"followersCount":0,"ecosystem":"BNB Chain","applyGuide":null,"weight":0,"participationForm":"IRL","field":"bnb chain","email":"operation@dorahacks.com","contacts":"Others,bnbchain","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":true,"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":{"id":539,"name":"BNB Smart Chain for all (Infra/dapp wishlist of BSC) - BNB Chain Tracks","judgingCriteria":"judging criteria","weight":0},"bountyObjs":[]},{"id":12144,"hackathon":{"id":382,"tabSet":[{"id":653,"name":"Prize","slug":"prize","description":"# Over $490k in Prizes Up for Grabs!\n\nThe stakes are high, with a whopping $492,000 prize pool up for grabs!
