\n\n## Tracks\n\n
\n\n### ***· Network Drive - Best use of IPFS/Filecoin for file storage - $12,500***\n\nThe Interplanetary Filesystem (IPFS) is a peer-to-peer network and protocol designed to make the web faster, safer, and more open.\n  Filecoin, the world’s largest decentralized storage network, allows users to store, request, and transfer data via a verifiable marketplace.  \n\nHow to start with Filecoin and IPFS: https://ecosystem-wg.notion.site/Getting-Started-With-IPFS-Filecoin-c00526cf97ba4087ba5c3ad5f5337a58\n\n
\n\n### ***· Multi-Chain Storage with Filecoin Network - $20,000***\n\nMulti-Chain Storage (MCS: https://mcs.filswan.com) is a smart-contract-based cross-chain storage gateway that is integrated with oracle technology. It accelerates the mass adoption of decentralized storage by bridging multiple blockchain networks. \n\n What’s MCS SDK: https://docs.filswan.com/multi-chain-storage/developer-quickstart/sdk\n\n
\n\n### ***· Computing Over Data - $15,000***\n\nComputing over data is the key scenario of 1PFS/Filecoin Network. This track is\nto encourage developers to develop apps based on data stored on Filecoin. Some example ideas can be climate data analysis, New York subway data, health data or other scientific data.\n\n
\n\n### ***· Forest - $1,000USD***\n\nForest is the rust node for the Filecoin network. The Forest team has put together some good first issues as bounties for the hackers at FILToronto. In order to solve these bugs/bounties you will need to have an understanding of the Filecoin protocol, some level of proficiency in rust programming language, and be able to install, run and debug with the Forest client.This hackathon prize is for the individual(s) who solves the most bounties/bugs correctly. This will be submitted directly to the Forest repository as draft PRs.\n\n- Forest repo: https://github.com/ChainSafe/forest\n\nBounties\n\n- Bounty 1: https://github.com/ChainSafe/forest/i ssues/1515\n- Bounty 2: https://github.com/ChainSafe/forest/i ssues/1512\n\nPrizes\n\n- Bounty 1: $500 USD\n- Bounty 2: $500 USD\n\nJudging Criteria:\n\n- Accuracy of the solution.\n- Number of bounties/bugs solved.\n- Quality of the PRs.\n- Creativity.\n\n# Bonus Track\n
\n\n### ***· Community Choice - $2,500***\n\nThe Twitter community will be able to share their favourite submissions in the hackathon! Community Track aims to judge projects based on community engagement and project quality.\n\nTo be eligible for Community Track:\n\n- A builder must tweet as you decide the project name and a short intro. Project video, design, and project link could be optional.\n- Must tag @0xFilSwan community.\n- Get community engagement in terms of retweets. (Highest RT with quality project wins)\n
