Interplanetary Consensus (IPC) is a new hyper-customizable scalability framework for both horizontal and vertical scaling, currently rooted to Filecoin and designed to be multi-chain!

Prizes will be awarded to the most meaningful usage of a custom IPC subnet, where you deploy your custom subnet(s) and utilize general message passing to perform tasks e.g. transactions, data aggregation etc.

Ideas – build subnets:

• For games (board games, turn-based games, or similar)

• For computation (Compute over Data, programming pipelines, etc)

• With interesting FVM runtimes: this could be existing blockchain VMs or components like zkEVM, fhEVM, CairoVM, MoveVM, AgoricVM or similar. Or this could be broader virtualization technologies like: Cloudflare Workers, Docker, or even FirecrackerVM.

Internet grade applications need internet grade bare metal infra and enormous storage networks. Filecoin provides simple to use storage helpers, EVM compatible Filecoin Virtual Machines and also connects with powerful providers via the storage market protocol itself. Build your internet grade app on Filecoin directly or in combination with IPC.

Please, see bounty above for more details and documentation for this prize.

Fileverse is an onchain collaboration alternative to Notion and Google Workspace. With Fileverse's fresh HeartBit SDK you can enable novel onchain user interactions directly on your app and generate granular user analytics trackable on Dune.

HeartBits are provable, time-based onchain "Likes" that people generate by simply engaging with your app, website, onchain media, Frame or OpenAction! The SDK also allows you to easily deploy Frames and Open Actions with gasless transactions.

Some project ideas to consider building: -Integrate HeartBits to your app or website. -Create an analytics-viewing Frame/OpenAction for HeartBit (e.g., when interacting with Frame number of HeartBits their address has generated displayed and how they rank compared to other addresses that own HeartBits) -Create and post an innovative HeartBit-enabled Frame on Farcaster or Open Action on Lens. -Build an app/Frame/OpenAction that allows people to mint and share HeartBits with their followers on Farcaster/Lens accounts. -Build a Frame/OpenAction mini-game leveraging HeartBits (e.g., click-based game)

Build dApps which can be used by web3 users. You can build your own usecase, mentioning the problem and how your hack is the solution. You can leverage Account Abstraction, social logins, for web3 onboarding aspects. You could also use communication protocols and support interoperability for the product. This product could be focused on Defi, UX, Staking, SocialFi, Wallet, Off ramp and on Ramp etc.

Few ideas that you could consider :

• Explore ERC 4337 AA and ERC 1155 token standard, your NFT token is the smart account.
• Use passkeys to sign transactions - using FaceID, touchID
• Create a wallet which can get integrated to your social accounts.
• Use Liquidity protocols like https://aave.com/ and create a defi focused tool.
• Build platform for token gated community
• Explore different EIPs and ERCs relevant to your product

Gnosis Pay introduces the first decentralized payment network, bridging traditional finance and decentralized finance (DeFi) by integrating with conventional payment systems like Visa.

For this hackathon we would like to see developers build applications that integrate with Gnosis Pay Accounts. You do NOT need a Gnosis Pay card to work on this prize.

Gnosis Pay accounts are just Safe Accounts that have the following two modules attached: the Delay & Role Modules(see in documentation below). You can build either new modules or integrations with existing modules to create solutions for Gnosis Pay.

Here are some project ideas that we're looking for:

• E-commerce payment gateway
• Subscription Management platform - fix a spendable amount from gnosis pay safe account, get points for timely payment and convert in spendable token EURe
• Hook integration with Uniswap or Pancakeswap on a Gnosis Pay Safe Account

Below are the links to the Gnosis Pay documentation & Telegram chats w/ the Gnosis Pay engineering team and DevRel

Create an integration with a web3 protocol that you think will be helpful to web3 users and the builders of gnosis chain. You can look at what integrations are already supported and how you can expand by contributing a proof-of-concept, for example, build smart contract helpers. You can even build a UI components for different usecases. Gnosis chain has super low transaction fees in stable token xDAI. Make use of this opportunity to develop something for the community of Gnosis Chain builders.

For example, Delegated Voting Mechanism: Implement a delegated voting mechanism for Uniswap governance proposals on Gnosis Chain, allowing users to delegate their voting power to trusted entities or community representatives.

Create a full fledged dApp that utilizes Hashi, an EVM Hash Oracle Aggregator, designed to facilitate a principled approach to cross-chain bridge security. Hashi aims to create “additive security” to cross-chain messages by aggregating block headers from different sources.

A block header will be considered valid only when a number of block sources (oracles) above a certain threshold report the same result. Hashi is the first step towards a principled approached to bridges and will play a key role in the Gnosis Chain interoperability roadmap. Utilize the message dispatching feature using Yaru and Yaho and create a cross chain application.

Read more about Hashi in the documentation linked below.

The Foundry template makes it easy to get started with both the on-chain and off-chain parts of a coprocessor application. This provides a starting point for building powerful new applications on Ethereum that offload computationally intensive (i.e. gas expensive), or would be difficult to implement Solidity.

We are awarding $3,000.00 to the top projects that build an application using the RISC Zero zkVM. There are no specific use cases we are looking for, so be as creative as you’d like!

RISC Zero unlocks the ability to bring identity from anywhere on-chain. Bonsai Pay and zkKYC demonstrate the power of integrating Google and ID.me identities on-chain, by verifying JWTs within the zkVM. We believe this is just the beginning, and want to see teams take this further, by building on top of these demos or by integrating new sources of identity.

We are awarding $2,000.00 to the top projects that build an application advancing on-chain identity with RISC Zero. Teams may use the Bonsai Pay, zkKYC, or jwt-validator examples as their starting points. Teams may also integrate new forms of identity, such as DKIM signatures, verified bank statements, digital passport documents, passkeys, key transparency trees, or any other source that will advance the state of on-chain identity. The award will be split between the best submissions.

We look forward to seeing the creative ways in which developers integrate on-chain identity into their applications. Let's push the boundaries of what's possible with identity, leveraging the powerful new zkVM ecosystem!
