But what happens when we sprinkle a bit of AI magic into this mix, now that FVM enables programmability on Filecoin? Dream up cutting-edge solutions with us at this workshop, on new realms of possibilities with FVM and AI that you can use at for your project submissions!\n\n[A Builder’s Guide to Filecoin Virtual Machine Development Recipes](https://dorahacks.io/hackathon/filecoin-data-economy/kick-off-summit-&-workshops)
\nWelcome to the ultimate creative kitchen for developers! In this workshop, we're diving deep into secret coding ingredients of FVM, for you to craft something extraordinary. We’ll cover a smorgasbord of FVM recipes designed to cater to a variety of tastes and use cases, from simple data storage to dApp development on Filecoin.\n\n\n# InterPlanetary Consensus (IPC): Challenges\n\n**Total Prize Pool**: $15,000 (paid in FIL)\n- **Grand Prizes**: 1st prize $5000 , 2nd prize $3000 , 3rd prize $2000\n- **Runners up**: 10 teams (10x $500) \n\n\nInterPlanetary Consensus (IPC) is a breakthrough scalability framework from the creators of Filecoin, IPFS & FVM, that unlocks planetary-level performance for web3, while delivering frictionless developer experiences to power a new generation of apps that break web2 limits.\n\nIPC provides recursive scaling of L2+ subnets, anchored to a parent L1. Subnets follow hierarchical consensus from child to parent networks, borrowing the security of the parent network and periodically checkpointing the entire chain state to the parent. Subnets are highly customizable and can be temporal, allowing subnet operators to spin up and take down subnets, for various needs, including sharding dApp workloads for higher throughput. This is especially crucial for scaling the dweb!\n\nThe IPC stack is cutting edge and highly experimental - you’re an early adopter in this hack! We challenge hackers to dive deep into the resources, chat with technical mentors and build never before seen solutions!\n\n⚡**Scaling with InterPlanetary Consensus**: Most meaningful deployment of a dApp on a newly launched custom subnet, utilizing General Message Passing (GMP). Create a custom purpose subnet using InterPlanetary Consensus (IPC) and a dApp that utilizes General Message Passing (GMP) between the subnet and its parent network. This is early developer access to this technology and MVPs are welcome! \n\n🛠️ **Custom protocols with InterPlanetary Consensus**: Best Use of Custom Syscalls or Built-in Actors to extend the Filecoin Virtual Machine (FVM). Use IPC to deploy a custom subnet, develop functionality that goes beyond what you can do natively with just Solidity. Use custom syscalls and Rust built-in actors in the Filecoin Virtual Machine (FVM) to achieve this. This is early developer access to this technology and MVPs are welcome!\n\n🖥️ **Compute with Interplanetary Consensus**: Best Deployment to IPC-powered Testnets for Computation Use Cases. Use an IPC-powered subnet for executing computation tasks (e.g. Fluence). Focus on practical computation applications.\n\n\n🃏 **Wildcard**: Some ideas don't fit any categories! The Wild Card prize is for out-of-the-box ideas built on FVM that contribute to building the new open data economy using Filecoin.\n\n**📚Workshops**

This hackathon is all about bringing together the brightest minds to push the boundaries of what's possible in web3. Imagined by PL Architect in collaboration with our flagship sponsors, [Filecoin](https://filecoin.io) and [InterPlanetary Consensus (IPC)](https://ipc.space), we are rallying developers from Asia and across the globe to explore and build on the [Protocol Labs Ecosystem](https://www.plnetwork.io/) tech stack. With a focus on Filecoin and IPC, here’s what we’re aiming for:\n- **Harness Data Value:** Tap into decentralized networks to maximize data utility.\n- **Innovate for Scalability:** Develop with InterPlanetary Consensus for cutting-edge scalability.\n- **Create with Filecoin:** Bring to life dApps that enhance the Filecoin ecosystem.\n- **Smooth Out the Filecoin Experience:** Aim for projects that refine participation in the Filecoin network.\n\nWinners will be showcased to our accelerator programs with leading partners, including Longhash Ventures & Graph Paper Capital, and be exposed to our extensive investor & mentor network. \n\nThat's our vision for sparking an open data economy revolution.\n\n# About Us\nAt **Protocol Labs Architect** we believe *The Ecosystem* outperforms *The Corporation* as the dominant driver of progress for humanity. Our craft is the structured and programmatic design and growth of internet-scale ecosystems in computing.\n\nOur global programming supported:\n - 63,000 hackers with $1.6M+ in prizes\n - 602 grants awarded across categories\n - 300 teams graduated from our accelerators; these early-stage teams have raised > $440M+ in venture capital to date\n\n**Filecoin**\nFilecoin is the L1 blockchain and storage network uniquely poised to power the open data economy. The mission of Filecoin is to create a decentralized, efficient, and robust foundation for humanity’s information.\nThe Filecoin Virtual Machine, launched in March 2023, brings programmability to Filecoin, & has already gained traction with thousands of developers.\n\n**InterPlanetary Consensus (IPC)**\nWith IPC, decentralized apps can reach planetary-scale through recursively scalable subnets, sub-second transactions, robust compute workloads, and highly adaptable WebAssembly runtimes tailored to dev requirements.\nIt enables the creation of flexible, living networks of customizable sidechains or \"subnets\", which can achieve massive scaling by running parallel chains that interoperate with one another.\nThe journey begins with supercharging devs’ capabilities on the Filecoin network.\n\n**Fleek**\nFleek gives developers everything they need to seamlessly build Web3 apps and services that are edge-optimized for performance and helps with decentralized hosting, storage, CDN and more.\n\n**Push Protocol**\nPush is the communication protocol of web3. Push protocol enables cross-chain notifications and messaging for dapps, wallets, and services tied to wallet addresses in an open, gasless, and platform-agnostic fashion. The open communication layer allows any crypto wallet /frontend to tap into the network and get the communication across.\n\n**Tableland**\nTableland is an open source, permissionless cloud database built on SQLite, enabling tamperproof data interaction for apps, data pipelines, or EVM smart contracts. Tableland stands at the intersection of blockchain's security and traditional databases' flexibility, offering a decentralized solution for relational data management.\n\n\n# Key Dates\n- Opening ceremony (19th Feb)\n- Workshops (20-23rd Feb)\n- Submission deadline (7th Apr)\n- Winners announced (17th Apr)\n\n\n# Startup Challenge\n**Total Prize Pool: $500,000 USD** (in accelerator seed funding)

It currently includes 5 custom syscalls including hashing algorithms such as blake2 and crc64, password encryption algorithms such as pbkdf2 and argon2, along with non-verifiable prng.\n\n# How it works\nI created multiple custom syscalls and linked it to a custom kernel. These syscalls allow users to add functionality to the smart contracts which wouldn't have been possible with native solidity contracts.\n\n**Checkout [IPUP](https://github.com/parthg1901/ipup/blob/main/README.md) for more information.**\n\nCurrently there are following syscalls -\n1. **Blake2 Hashing** - Blake2 is a cryptographic hash function which provides high performance, versatility and security to the users. It is not natively supported in solidity, however it's highly needed in cryptographic operations.\n2. **CRC** - CRC (Cyclic Redundancy Check) is an error-detecting code used in digital networks and storage devices to detect accidental changes to raw data. It operates by generating a fixed-size checksum (typically 16, 32, or 64 bits) based on the data being checked, which is then appended to the data or transmitted alongside it.\n3. **Pbkdf2** - PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function that is used to securely derive cryptographic keys from passwords or passphrases. It's a widely-used algorithm for deriving cryptographic keys from passwords, and it's designed to be resistant to brute-force attacks.\n4. **Argon2** - Argon2 is a key derivation function that was selected as the winner of the Password Hashing Competition (PHC) in 2015. It's designed to securely hash passwords and other sensitive information while also being resistant to various types of attacks, including brute-force, dictionary, and side-channel attacks. Argon2 is considered to be one of the most secure and efficient password hashing algorithms available today, and it's being widely adopted in various applications and security protocols.\n5. **Non Verifiable Randomness** - The custom syscall for Non-verifiable PRNG is created using Box-Muller method(shown in the image below). It uses rand crate from rust.\n\n![iS9La.jpg](https://cdn.dorahacks.io/static/files/18eb90b864215eecd5b2bcd4cf994696.jpg)\n\n# How to use\n1.

So, I'll be adding these once I figure out a way to input strings.\n\nI'll be accepting open-source contributions to this project after the hackathon, it'll be great to have various syscalls in a single place.","images":["https://cdn.dorahacks.io/static/files/18eb891c21435ced17a7dd54293b6e53.png"],"team":"Parth Gupta - Created custom syscalls for the IPC subnet.","github":"https://github.com/parthg1901/ipup","demo":null,"video":"https://youtu.be/Nc191mSVvGU?si=q_EaXGxe-dWMephX","socialTwitter":"gparth375","socialFacebook":null,"socialInstagram":null,"nftId":null,"haxonBuidls":[{"id":11802,"projectId":11161,"name":"IPUP - Interplanetary Utility Package","track":"InterPlanetary Consensus (IPC)","bounties":[],"haxonId":298,"haxonName":"Filecoin | InterPlanetary Consensus (IPC): Data Economy Hackathon","status":2,"haxonCreateAt":"2024/02/19 00:00:00 UTC"}],"kudoData":null,"bountyObjs":[],"tracks":[],"badges":["{\"schema\":\"BADGE\",\"d\":{\"index\":\"b9200\",\"badgeType\":\"buidl\",\"path\":\"/buidl/11161/achievement/b9200\",\"ownerId\":11161,\"iconName\":\"b0\",\"updatedDate\":\"2024/04/24\",\"title\":\"Filecoin | InterPlanetary Consensus (IPC): Data Economy Hackathon\",\"detail\":\"Participation\",\"tag\":\"Hackathon\",\"imageUrl\":\"https://cdn.dorahacks.io/static/badge/b0_Filecoin~c32|~c32InterPlanetary~c32Consensus~c32(IPC):~c32Data~c32Economy~c32Hackathon.webp\",\"shareImageUrl\":\"https://cdn.dorahacks.io/static/badge/b0_Filecoin~c32|~c32InterPlanetary~c32Consensus~c32(IPC):~c32Data~c32Economy~c32Hackathon.jpg\",\"id\":9200,\"metaInfo\":{\"type\":\"HACKATHON_PARTICIPATION\",\"hackathonId\":298,\"title\":\"Filecoin | InterPlanetary Consensus (IPC): Data Economy Hackathon\"},\"createdAt\":1713963242,\"updatedAt\":1713963242,\"type\":0,\"subjectId\":298,\"metadata\":{},\"buidl\":11161}}","{\"schema\":\"BADGE\",\"d\":{\"index\":\"b9176\",\"badgeType\":\"buidl\",\"path\":\"/buidl/11161/achievement/b9176\",\"ownerId\":11161,\"iconName\":\"b1\",\"updatedDate\":\"2024/04/24\",\"title\":\"Filecoin | InterPlanetary Consensus (IPC): Data Economy Hackathon\",\"detail\":\"Winner\",\"tag\":\"Hackathon\",\"imageUrl\":\"https://cdn.dorahacks.io/static/badge/b1_Filecoin~c32|~c32InterPlanetary~c32Consensus~c32(IPC):~c32Data~c32Economy~c32Hackathon.webp\",\"shareImageUrl\":\"https://cdn.dorahacks.io/static/badge/b1_Filecoin~c32|~c32InterPlanetary~c32Consensus~c32(IPC):~c32Data~c32Economy~c32Hackathon.jpg\",\"id\":9176,\"metaInfo\":{\"type\":\"HACKATHON_WINNER\",\"hackathonId\":298,\"title\":\"Filecoin | InterPlanetary Consensus (IPC): Data Economy Hackathon\"},\"createdAt\":1713962920,\"updatedAt\":1713962920,\"type\":1,\"subjectId\":298,\"metadata\":{},\"buidl\":11161}}"]}}
