As a seasoned player in the world of decentralized finance, you know that derivatives are a crucial component of any growing ecosystem. They allow users to manage risk, speculate on price movements, and expand the potential use cases of a blockchain platform.\n\nThese tools will help to drive the growth and adoption of the Cardano Defi ecosystem, which is already home to a wide range of primitives such as DEX, borrowing and lending, and stablecoins.\nBy focusing on the development of derivative-focused protocols, we aim to accelerate the growth and potential of the Cardano platform.\n\nThis is your chance to push the boundaries of what's possible with derivatives on the blockchain.\n\n# Track Two: Aggregators\n\nAs a web3 pro, you know aggregators are essential for a consolidated user experience. They allow access to multiple sources through a single interface, making it easier to navigate growing ecosystems. \n\nAs part of the hackathon, we're seeking aggregator solutions like Nansen and BitMetis, data/assets tracking, and NFT marketplaces. NFT aggregators, in particular, have the potential to transform the way we interact with NFTs on the platform.\n\nThe aggregators track is all about building tools that can gather and synthesize data from multiple sources. We're looking for rebels who can shake up the way we access and use information with their groundbreaking projects across on-chain data tracking, gameFI or NFT utility aggregation.\n\n# Track Three: Zero Knowledge\n\nAnd in the ZK track, we're on the hunt for those who can use blockchain to enable secure transactions and communication without revealing any private information. If you're ready to push the limits of privacy and security on the blockchain, this track is for you.\n\nZero-Knowledge-Proof is an essential infrastructure utilities for every blockchain ecosystem. ZK technology is becoming essential on every Layer 1 including Cardano. Some of the key use-cases of ZK technology includes scalability, identity, privacy & data verification. \nSome examples of zero knowledge use cases that could be developed on the platform include private transactions, anonymous voting systems, and secure messaging.\n\nDon't miss out on the opportunity to shape the future of blockchain technology. Join the hackathon and put forward your team’s skills to win the track of your choice."},{"id":133,"name":"Why Build on Cardano","slug":"why-build","description":"# Why Build on Cardano?\n\nTake a look at a few cases below:\n\n**Building on Cardano: Book.io and Mesh**\n\n![youtube](https://youtu.be/SnTYKHDZ8rY)\n\n**PPP 030101 - Welcome and Introduction**\n\n![youtube](https://youtu.be/X80uNXenWF4)\n\n**Building on Cardano: overcoming challenges and the road to mass adoption**\n\n![youtube](https://youtu.be/bASyKD2dnys)"},{"id":134,"name":"Submission Guide","slug":"guide","description":"# What to submit \n\n- **Pitch Deck/Intro Deck**: This should include your contact information such as Telegram, Twitter, Email, etc.\n\n- **Whitepaper/Litepaper**: A document that clearly outlines your project, its goals, and how you plan to achieve them.\n\n- **Demo Video**: While not mandatory, a demonstration video can significantly enhance the understanding of your project.\n\n- **Project Website**: If available, a link to your project's website can provide the judges with additional insights into your project.\n\n- **Github link**: This is optional but it can be very helpful if your project involves coding.

When do they end?**\n\nSubmissions will be accepted starting May 29, 2023, and until July 3rd, 2023.\n\nAlso, those who want to pre-register can go to the Hackathon home page [here](https://dorahacks.io/hackathon/cardano-emurgo-build-2023/detail) and click “Register as Hacker” in the upper right.\n\nYour email address will be recorded and then you will be able to post anything on the Hackathon idea board [here](https://dorahacks.io/hackathon/cardano-emurgo-build-2023/ideas).\n\n
\n\n**Where do I submit my build?**\n\nThe projects can be submitted on the DoraHacks portal [here](https://dorahacks.io/hackathon/cardano-emurgo-build-2023/detail).\n\n
\n\n**If our work consists of more than one “product” that can be used separately, but are also interoperable, can this be submitted as one project, or should it be multiple projects?**\n\nIf the product is submitted by one developer group, it should be considered a single submission. \n\n
\n\n**Can one team propose a submission in more than one track? Or just one per team?**\n\nIf the team believes they can maintain the same quality in two or more submissions, there are no restrictions.\n\n
\n\n**Can we share and submit a private GitHub with the judges?**\n\nYes, you can share a private GitHub repository with the judges. You will just need to grant them the necessary access permissions. This way, they can review your code while maintaining its confidentiality.\n\n
\n\n**What happens to the intellectual project rights of the submissions?**\n\nAnything developed during the hackathon remains under the ownership of the developers. The hackathon is only to distribute grants and support the community.\n\n
\n\n**Is a dApp on a preproduction test network good enough to submit?**\n\nYes, it fits the Hackathon. dApps on a preproduction test network are indeed acceptable. It’s a common practice to initially develop and test dApps in such environments before they’re deployed onto a mainnet. This allows developers to detect and fix any issues without risking real assets.\n\n
\n\n**When is the deadline for build submissions?**\n\nSubmissions open on May 29 and will close on July 3. You can register and submit your BUILD during these dates.\n\n
\n\n**What is the process to register a proposal?**\n\nPlease visit [here](https://dorahacks.io/hackathon/cardano-emurgo-build-2023/guide) for information.\n\n# BUILD FAQs\n\n**What are the three developer tracks?**\n\nDerivatives: Creating financial products that go beyond DeFi, but incorporate Cardano’s decentralized blockchain. There are many types of derivatives in the financial world that have not been brought to blockchain.\n\nAggregators: Solutions that act like data hubs to collect different data points regarding Cardano dApps for traders, analysts, etc. to make more informed decisions. Can gather information about Cardano DeFi projects or Cardano NFTs.\n\nZK-rollups: Building solutions using zero-knowledge technology such as privacy solutions, bridges, and/or a ZK layer for the Cardano blockchain. \n\n
\n\n**What types of workshops will there be during the hackathon?**\n\nThere will be more AMAs during the course of the hackathon. \n\nOne is being planned for the official [Cardano EMURGO BUILD 2023 Hackathon Discord server.](https://discord.com/invite/ynW4qpvzra)\n\nSecond, there will be technical workshops between EMURGO and developers building tools on Cardano.\n\nMost real-time information can be gathered in the Discord channel so please join to receive the latest updates regarding events and other details.\n\nFor those who missed the workshop live stream, you can check the recordings [here](https://dorahacks.io/hackathon/cardano-emurgo-build-2023/workshop).\n\n
\n\n**Are there any requirements for the code developed for the hackathon?**\n\nThe code can be private for submission, such as a private GitHub repository. There is no requirement to make it public. \n\n
\n\n**Are there any restrictions post-hackathon regarding the code developed during the hackathon?**\n\nNo, neither EMURGO nor DoraHacks will claim any ownership of the code created by the teams. \n\n
\n\n**What happens if the participants use a third-party tool for their project?**\n\nThird-party APIs or developer tools created for Cardano are fine to use. The one restriction is participants cannot copy the code from other projects.\n\n
\n\n**Are there any legal restrictions?**\n\nIn most cases, there are no restrictions on the prize pool. In some cases, participants may come from countries where cryptocurrencies are banned or blocked. In those cases, these participants will not be able to claim their prize money. \n\nEvery team is responsible for checking their own local laws and regulations regarding crypto transactions.\n\n
\n\n**Is it possible to receive feedback during the duration of the hackathon?**\n\nIn the Discord server, hackathon teams can ask the organizers about the ideation of the project, the proper category for submission, and other general questions. Both EMURGO and DoraHacks officials will monitor the Discord channels and answer queries in real time.\n\n
\n\n**Does an MVP count?**\n\nIt’s possible to present a pitch deck or demo of the project but to increase the chances of winning, presenting code is better. There are four criteria that will be used to judge every entry:\n\n**1.** Innovation and necessity to the Cardano ecosystem(20%) \n\n**2.** Maturity of the tech and product (40%)\n\n**3.** Go-to-market strategy, user acquisition strategy, and community growth strategy (20%)\n\n**4.** Team and relevant experience (20%)\n\nEvery project will be scored on all of these four criteria.\n\n
\n\n**Can a participant be in two different builds presenting on different tracks?**\n\nYes, this is possible. It’s ultimately up to the participating teams and developers to decide.\n\n
\n\n**Do we build a pitch deck and demo? Video? Website?**\n\nThe minimum requirement is a pitch deck. Any additional information is a bonus, so if teams have time to create a demo of the product, a static webpage that shows how it would look, or any other details, it will help their chances of winning. \n\n
\n\n**Is it necessary for the Hackathon code to be entirely new? I’ve been involved in a project for a while that hasn’t been launched, but we’ve made some progress.**\n\nNo, it’s not necessary for the code to be 100% new. However, it is essential that you are the rightful owner of the code. EMURGO will inspect the code and carry out the necessary verifications.\n\nCould you give more specific information on what constitutes an aggregator?\n\nGalxe and Nansen are good examples of an aggregator. Please check their sites at [https://galxe.com](https://galxe.com/) and [https://www.nansen.ai](https://www.nansen.ai/)\n\n# BUILD FAQs\n\n**How is the prize pool divided?**\n\n![image.jpeg](https://cdn.dorahacks.io/static/files/18858909df7d3f6d3ba36844439bfb03.jpeg)\n\nThere will be $100,000 USD in the prize pool. It’s divided as follows:\n\n- First Prize: $20,000\n- Second Prize: $10,000\n- Third Prize: $3,000\n\nEach of the three tracks will have the same amount distributed to the winners as mentioned above. \n\nAdditionally, EMURGO could invest up to $1.9 million USD in these successful projects. The additional investment is not part of the prize for winning the hackathon and is subject to extra due diligence by the EMURGO Ventures team.\n\n
\n\n**What are the terms and conditions for the prize money?**\n\nThere will be more details on the terms and conditions once submissions are open. For the prize money, there will be a few conditions. For investments, these will require more formal processes and projects will be expected to sign formal legal documents that can include a SAFE, SAFT, or a SAFE + Token Warrant agreed upon by both parties. \n\n
\n\n**How do I best guarantee funding for my idea? Any criteria?**\n\nThe criteria are stated above. Additionally, solving problems in the Cardano ecosystem is important as this is a Cardano hackathon, as is the potential impact the project could create. Another important detail is how well the team uses existing Cardano ecosystem tools.\n\n
\n\n**Do we need to provide a separate pitch/meeting if we want additional investment/grant money from EMURGO and/or EMURGO Ventures? Or is winning the hackathon a foot in the door?**\n\nWinning the Hackathon is the first step.\n\n
\n\n**Will the Hackathon prizes be paid out in ADA or stablecoins?**\n\nThe prizes will be awarded in ADA. However, it is up for future discussion."},{"id":327,"name":"Results","slug":"results","description":"# Cardano EMURGO BUILD 2023 Hackathon Recap and Result Announcement\n\nThe list of winners for the Cardano EMURGO BUILD 2023 is now available!
