\n\n### Track 1: Leverage EVM Extensions on the Evmos Testnet (Higher incentive)\n\nEvmos would like to invite developers to build and submit dApps that leverage the EVM Extensions launched onto our Testnet. Our stateful precompiles called EVM Extensions represent the next frontier for Evmos and bring the cross-chain vision closer to fruition. Evmos encourages all developers to take advantage of these novel implementations and generate new possibilities with their intuitive and exciting solutions.\n\nTo participate in the EVM Extensions Track, your project must be built using the EVM Extensions on Evmos's Testnet. (More detail on EVM Precompiles will come out before launch).\n\n
\n\n### Track 2: Buidl on Evmos: Infrastructure & Tooling\nAre you ready to take on the challenge of building solutions that make building on Evmos a seamless and secure experience? For the Infrastructure and Tooling track, Evmos is looking for participants who can create tools that enhance security, simplify debugging, improve testing, and optimize the developer experience. Evmos is calling on all developers who are passionate about cross-chain innovation and want to contribute to a stronger and more robust Evmos ecosystem.\n\nAn Idea: Construct a webapp featuring friendly UI/UX to create all Cosmos and EVMOS supported governance proposals with the ability to query, validate, and upstream proposals to Commonwealth and on-chain. Another idea includes \n\n
\n\n### Track 3: Buidl on Evmos: DeFI\n\nFor this track, Evmos invites you to rethink and redefine DeFi by developing innovative applications, tools, or platforms that push the limits of traditional finance. Your project should prioritize accessibility, usability, and inclusivity, making DeFi more accessible to the general public. Whether you're creating a new lending protocol, designing a user-friendly interface, or developing a game-changing DEX, Evmos is excited to see your unique perspective on the world of decentralized finance while leveraging the strength of Evmos.\n\nAn Idea: Display an intuitive way to visualize all approvals (token, public key signature, authz, etc.) given to various apps and ecosystems based on address and offers a way to revoke any if necessary.\n\n
\n\n### Track 4: Buidl on Evmos: DAO & Community\n\nThe DAO and Community track encourages developers to build tools that increase transparency and accountability while remaining adaptable in a cross-chain ecosystem in Evmos. This track is ideal for projects that aim to create community-led decentralized organizations that can operate autonomously and transparently. Developers are encouraged to build tools and infrastructure that can enable decentralized decision-making, decentralized funding, and incentivization mechanisms to drive community participation and engagement.\n\nSubmission materials should highlight the use of Evmos and cross-chain interoperability, as well as the project's ability to promote transparency and accountability. Projects that use innovative approaches to incentivizing and engaging community participation will be highly regarded by the judges.\n\nAn Idea: A platform to pull in Commonwealth data and interactions alongside proposals with validators voting data to display how validators vote over time. Delegators can then use this information to change delegation or understand how their validators tend to vote."},{"id":118,"name":"Requirements","slug":"requirements","description":"# Entry Requirements, Judge Criteria & Process\n\nAll submissions needs to deploy to our Evmos Testnet and incorporate these following:\n\n- utilize our EVM Extensions capabilities or Buidl on Evmos\n- incorporate unique use cases or implementation\n- a demo video illustrating the project in comprehensive detail\n- links to your code repository, website and socials to help judges review your submission.

The focus of these hackathons will center around our EVM Extensions.\n\n**What are EVM Extensions?**\n\nEvmos has introduced stateful precompiles called EVM Extensions, which are unique to its implementation. The ability of EVM Extensions on Evmos will unlock both blockchains and individual applications to customize and leverage the functionality of IBC and other Cosmos SDK modules. These extensions extend the EVM's capabilities beyond its original specification without compromising equivalence with Ethereum's execution layer.\n\nWith EVM Extensions, developers can create their own business logic for connecting with other smart contracts and appchains in the Cosmos ecosystem. Applications are no longer limited to a single blockchain and can make smart contract calls to IBC modules to communicate with other chains, securely send and receive assets across chains, stake EVMOS tokens, and even manage accounts on other blockchains to access any functionality built elsewhere.\n\n# Prize Pool\n\nThe prize pool (98k USDT) will break down as follow:\n\n
\n\n### Leveraging EVM Extensions\n\n- 1st: 17k USDT\n\n- 2nd: 13k USDT\n\n- 3rd: 8k USDT\n\n
\n\n### Buidl on Evmos: Infrastructure & Toolings\n\n- 1st: 10k USDT\n\n- 2nd: 7k USDT\n\n- 3rd: 3k USDT\n\n

It is challenging and not scalable to add custom implementations for each protocol, decode the data, and extract the slippage value.\n\nTo address this problem, a scalable solution is needed that would allow wallets to protect users from miner-extractable value (MEV) attacks targeting transactions with unset slippage (or set to 100%). One potential solution is to create an Ethereum Improvement Proposal (EIP) that standardizes the way slippage is encoded and decoded across all DeFi protocols. This would enable wallets to easily extract the slippage value from any transaction data and alert users if the slippage is unset or set to 100%, providing an additional layer of protection against MEV attacks. Alternative implementations that achieve the same goal are also worth considering.\n\n# **Circle [ $10,000]**\n\nCircle is a global financial technology firm that enables businesses of all sizes to harness the power of digital currencies and public blockchains for payments, commerce and financial applications worldwide.\n\nCircle is also the principal operator of USD Coin (USDC), which has become the fastest-growing, regulated and fully reserved dollar digital currency. USDC now stands at more than 32 billion and has supported about $1.4 trillion in transactions over the past year.\n\nToday, Circle's transaction and treasury services are giving rise to a new generation of financial services and commerce applications that hold the promise of raising global economic prosperity through the frictionless exchange of financial value.\n\n- **Embed Streaming USDC Payments into your App**\n\n - Guidelines\n\n - Add streaming USDC payments functionality to your app or marketplace\n\n - Enable users to choose monthly, daily, or per-second streaming\n\n - Enable streaming for inbound and outbound payments\n\n - Criteria\n\n - We want projects that are full MVPs that include code and not just a proof of concept in a PowerPoint. These should be functional and able to show the functionality in action.\n\n - Please show us how you got to the solution.

It is challenging and not scalable to add custom implementations for each protocol, decode the data, and extract the slippage value.\n\nTo address this problem, a scalable solution is needed that would allow wallets to protect users from miner-extractable value (MEV) attacks targeting transactions with unset slippage (or set to 100%). One potential solution is to create an Ethereum Improvement Proposal (EIP) that standardizes the way slippage is encoded and decoded across all DeFi protocols. This would enable wallets to easily extract the slippage value from any transaction data and alert users if the slippage is unset or set to 100%, providing an additional layer of protection against MEV attacks. Alternative implementations that achieve the same goal are also worth considering."}]},{"id":4860,"hackathon":{"id":126,"tabSet":[{"id":166,"name":"Schedule","slug":"schedule","description":"![2.jpeg](https://cdn.dorahacks.io/static/files/188dbef5f576d62c5d7720046ed8af9a.jpeg)\n\n\n![1.jpeg](https://cdn.dorahacks.io/static/files/188dbef8507b38aeeabe37042b5b0714.jpeg)"},{"id":168,"name":"Tracks","slug":"tracks","description":"![3_赛题-英-无码-16.jpg](https://cdn.dorahacks.io/static/files/18857a6eda3c5e423a72faa411a96fd6.jpg)\n\n# Project Recruitment Dashboard\n\nClick **[here](https://docs.google.com/spreadsheets/d/1NV8P6JQLjvs2DJUYmpOfsXe0hT-ec6xi5niG1EnoGjM/edit#gid=1098850878)** to view.\n\n# Category I: Building Parachains + Independent chains\n\nIn this category, you can use Substrate to build a custom blockchain challenge. In the near future, your chain will have the ability to access the Kusama relay chain for interoperability and plug-and-play security. The following ideas are meant to give you some inspiration. We want you to get creative and build the custom chain you think will be most useful to other builders of the Substrate ecosystem!\n\n- Game Chain\n- DeFi or Stable Coin Chain\n- Privacy Chain\n- DAO Chain\n- DID\n- Decentralized Market Chain\n- Other Ideas：Public voting chains,Computational chains (e.g. Golem), Permission chains, Prediction markets, Federal Prediction Machine.\n\n# Category II: Smart Contracts (and related)\n\n## Smart Contract Chain\n\nSmart contract chains are sandbox execution environments for small pieces of code that other developers can deploy without permission. Substrate provides a smart contract module based on EVM and Ink, which Kusama will definitely need to execute to deploy an active parallel chain. Some specific ideas could include smart contracts using other languages, such as assembly scripts, especially those with existing toolchains. In your opinion, what would a perfect smart contract chain look like?\n\n## Smart Contracts Platform\n\nThe Smart Contracts Platform provides an efficient platform for smart contract specification and execution. Substrate has the scalability to make developing a contract platform very easy. New contract platforms can be innovative in terms of efficiency of execution, contract security, and cross-chain invocation of contracts.\n\n## ink! Smart Contracts Developer Tools\n\nink! is a next-generation smart contract development framework developed by Parity that relies on Substrate's built-in pallet-contracts module to write WebAssembly smart contracts using Rust. As more and more developers use the ink! framework, we need additional support packages to help developers write secure and efficient smart contracts. These suites include, but are not limited to:\n\n- Contract testing environment for quick start and deployment.\n- Smart contract auditing specifications and tools.\n- Refinement of contract standards.\n- Monitoring, indexing, visualization of data on the contract chain, and more.\n\n# Category III: Blockchain Products and tools Tools\n\n- Testing suite / Operations tool\n\nCurrently, writing automated tests is not quite straightforward - for example for objects available in Truffle, Embark in Ethereum - and especially for specific blockchain functions on Substrate-based chains. A test suite allows to embed a test wallet in the suite and perform state tests in a deterministic way. The output should be a complete category, including issues and suggestions on how to fix them (if the fix is known). Ideally, the bug fixing process should be a crowdsourced effort. Until then, undetected bugs are automatically converted into issues and new categories in the central repository of recipes.\n\n- Substrate pallets tool suite\n- Governance Tools\n- Data Analysis Tools\n\n# Category IV: Open Tracks\nTry everything possible! In this category, we want you to push the limits of what is possible, to be creative, to break things!\n\nImprove the underlying Web3 technologies, such as peer-to-peer communication frameworks like libp2p, new consensus algorithms based on Substrate, node routing and lookups like DHT, and other things that can be used to help peer-to-peer financial, social activities, and more."},{"id":169,"name":"Prize pool and breakdown","slug":"prize-pool-and-breakdown","description":"Important notes on multiple prize eligibility:\n\n- The total prize pool for this hackathon is worth up to **42,852 DOT**,equivalent to **300,000 USD**.

Deeper Network has developed DEP, a powerful decentralized network protocol that can transform the network experience and foster new applications. The multifunctionality of DEP comes from its unique features, such as smart routing, edge computing, and content distribution. These characteristics help construct a more secure, more free, and more open Internet, creating innovative DApps using DEP. Here are some application scenarios to spark your creativity:\n\n- Oracle: You can develop an Oracle DApp by leveraging DEP's ability to interact safely with on-chain and off-chain environments. This can serve as a bridge, enabling smart contracts to interact securely and reliably with real-world data and services, thereby facilitating applications in finance, insurance, random prediction, and IoT, among other areas.\n\n- Zeronet: The Internet as we know it is centralized and subject to censorship. With DEP, you can develop a DApp similar to Zeronet, providing users with a censorship-resistant peer-to-peer Internet experience, thus promoting the development of a truly decentralized network.\n\n- Lightning Network: You can create a DApp that implements a Lightning Network-style payment channel using DEP's smart routing and edge computing capabilities. This channel will facilitate instant, high-frequency, bidirectional transactions on the blockchain, thereby enhancing the scalability and efficiency of cryptocurrency transactions.\n\n- Further Exploration: The potential of DEP is enormous, not limited to the above scenarios. DEP can serve as the underlying protocol for various other DApps, such as triggers, state machines, mail relays, etc. This opens up numerous avenues for developers to create breakthrough applications.\n\n## Judging Criteria\n\n- Originality (20%): How unique and innovative is your DApp? We value novel concepts and fresh perspectives.\n\n- Integration with DEP (30%): Your DApp should demonstrate powerful integration with the features and functionalities of DEP. It should show how to make the most of DEP's capabilities.\n\n- Utilization of DEP's Unique Capabilities (20%): Does your DApp effectively utilize the unique features of DEP, such as smart routing, edge computing, and content distribution? Show us how to fully leverage these.\n\n- Execution (20%): We will assess the quality of your implementation. The DApp should be feature-complete, error-free, and user-friendly.\n\n- Live Demo (10%): Show us your DApp in action. The live demo can highlight its features and functionalities in a real-world environment.\n\n## References\n\n- https://github.com/deeper-chain/dep-docs/tree/main\n\n- https://github.com/deeper-chain/deeper-chain\n\n- https://deeper-network-inc.gitbook.io/deeper-connect-knowledge-base/\n\n- https://doc.deepernetwork.org/\n\n# Gear Foundation\n\nThe [Gear Protocol](https://gear.foundation/) is a Substrate-based smart-contract platform that enables anyone to develop and run a dApp in a matter of minutes. The Gear Protocol is the most developer-friendly way to implement smart contracts with arbitrary logic and of any complexity. Gear smart-contracts run as WebAssembly programs so they can be compiled from many popular programming languages, such as Rust, C, C++ and many more.\n\nThe protocol ensures very minimal, intuitive and sufficient APIs for implementing programs and running them on multiple networks without having to rewrite them. From a technological point of view, the Gear Protocol is distinguished by fundamentally new features that enable you to create asynchronous programs with a completely new and previously unattainable user experience, namely - the Actor model for communication, the persistent memory concept and WebAssembly execution environment. The protocol dictates what actors should look like as communicating entities.\n\nThe Gear Protocol will assist with the transition to mass use of Web3 technologies by enabling the running of innovative dApps, microservices, middleware, and open APIs.\n\n## Bounty bonus amount: $3,000\n\n- $1,000/Project (3 projects in total).\n\nTeams who build the following ecological applications on the Vara Network driven by Gear Protocol will have the opportunity to receive rewards:\n\n- Ecosystem Support – Analytics, tooling, and sites for Gear awareness.\n\n- NFTs – Collections that break new ground, and/or include experimental aspects.\n\n- DeFi – Original work that leverage Gear’s Infrastructure.\n\n- Gaming – 100% onchain or infinite games that utilise async WASM VM.\n\n- DAOs & tooling – decentralised internet, gambling all things weird.\n\n- New Things – The most divergent ideas.\n\n# Manta Network\n\n[Manta Network](https://manta.network/) is the zk layer 1 blockchain with the fastest prover speed and most decentralized trusted setup that brings programmable privacy to web3.

It is a challenging and important problem for investors, traders, analysts, and regulators. Deep learning is a branch of machine learning that uses artificial neural networks with multiple layers to learn from large amounts of data and extract complex patterns and features. Deep learning models have shown remarkable performance in various domains, such as computer vision, natural language processing, speech recognition, and bioinformatics. Recently, deep learning models have also been applied to financial market prediction, with promising results. Some of the advantages of deep learning models for financial market prediction are: they can handle nonlinear and high-dimensional data; they can learn from both structured and unstructured data; they can capture long-term dependencies and temporal dynamics; they can adapt to changing market conditions; and they can incorporate domain knowledge and expert opinions. Some of the challenges of deep learning models for financial market prediction are: they require large amounts of data and computational resources; they are prone to overfitting and underfitting; they are difficult to interpret and explain; they are sensitive to noise and outliers; and they may suffer from data quality issues and ethical concerns.","teamDescription":"Our team consists of two members with different backgrounds and skills, who share a common interest and passion for financial market prediction using deep learning model.
