These projects will share a total of $947,580 in prizes provided by dozens of projects including Metis, 0x, and ZetaChain.

Next, Odaily Planet Daily will take you to get to know these 15 new star projects.

Infrastructure and Scalability

VeriFido

Hackathon Subpage: https://devfolio.co/projects/indy-780a

Keywords: Data Indexing

Introduction: VeriFido is positioned as a verifiable Ethereum data indexing service.

As it is very inconvenient to obtain application status directly from the original on-chain data, current projects generally rely on indexer services to retrieve key data required by the application. However, the current indexer services on the market have not reached the same level of decentralization and security as other components in the Web3 stack. In this case, data failures may lead to serious destructive consequences, especially for DeFi involving real money.

To address this issue, VeriFido proposes to integrate a fully verifiable indexing service into the above workflow. Through the VeriFido solution, applications can continue to enjoy the convenience of centralized indexing services without compromising decentralization and security. In addition, VeriFido will also integrate some on-chain dispute resolution solutions to ensure that smaller data indexing service providers can resist malicious attacks from larger groups.

In summary, VeriFido aims to improve the transparency and fairness of indexing services, thereby providing a more robust Web3 development environment.

PAT.IO station

Hackathon Subpage: https://devfolio.co/projects/patio-station-7ec1

Keywords: Streaming Service

Introduction: PAT.IO station aims to use the most decentralized, secure, and available Ethereum mainnet nodes as the infrastructure for streaming media to ensure the security of video and communication transmission.

As there are many different clients on the current Ethereum mainnet, PAT.IO station has conducted extensive research on node architecture in order to use Ethereum mainnet nodes for communication purposes, attempting to clarify how different clients work together as a whole and what the "rules" of communication between them are. PAT.IO station has searched for almost non-existent documentation and conducted extensive testing using various RPC and Mempool APIs.

PAT.IO station hopes to provide a truly usable solution for "communication censorship," a global issue.

Storylus

Hackathon Subpage: https://devfolio.co/projects/storylus-f120

Keywords: Historical Data Access

Introduction: There is currently no native way on Ethereum to access all historical states of the blockchain in a trustless manner. Ethereum has written over 19 million blocks, but smart contracts can only access the most recent 256 blocks, which is about 50 minutes of data.

Storylus is an open protocol available on the Sepolia testnet, which allows smart contracts to access all historical Ethereum data without trust through verifying the Ethereum blockchain on Stylus and providing storage proofs.

DeFi, NFT, Games

Egg Wars

Hackathon Subpage: https://devfolio.co/projects/egg-wars-a-game-on-base-d9bb

Keywords: Game

Introduction: Egg Wars is a strategy-based competitive game built on Base. Unlike short-term games that rely on incentives, Egg Wars aims to design a balanced basic mechanism to allow the game to "continue indefinitely" and provide continuous fun for players.

Bubblewars.io

Hackathon Subpage: https://devfolio.co/projects/bubblewarsio-6121

Keywords: Game

Introduction: Bubblewars.io is a fully on-chain large-scale multiplayer online game (MMO), where all the dynamics in the game come from ETH. Users need to absorb others' bubbles (seize ETH) to grow their own bubbles (accumulate ETH) in an endless field and use ETH to move their bubbles.

The core mechanism of Bubblewars.io is that players can join the game by generating an entrance (Portal), which is actually an independent EOA address, serving as the channel for players to enter and exit the game. All funds sent to the entrance address by players will be transferred to the application chain running Bubblewars and can be withdrawn from the entrance address after the proof cycle ends (ETH accumulated to the entrance address by devouring others' bubbles also belongs to the player).

Once players send enough ETH to the entrance address, they can launch bubbles to start the game, which involves devouring others' bubbles to absorb ETH for profit. You can devour all bubbles with smaller mass, while any opponent with greater mass can also devour your bubbles. The bubbles move within the game world based on the rules of momentum conservation, and to move the bubbles, you must launch ETH in the opposite direction. In addition, absorbing bubbles also involves energy transfer, so you can achieve acceleration or deceleration by absorbing bubbles.

The biggest problem currently existing in Bubblewars.io is that whoever has the most ETH will win. Therefore, Bubblewars.io plans to place resource nodes that can be absorbed by bubbles in the game to balance the competitive environment.

Michi Protocol

Hackathon Subpage: https://devfolio.co/projects/michi-protocol-afb6

Keywords: Points Market

Introduction: Michi Protocol is a trustless points trading market that uses ERC-6551 to create an address associated with a certain NFT, and these addresses can accumulate points through any existing protocol's point activities (such as EigenLayer).

By selling the above NFT, the accumulated points in the address will also be sold together, thereby achieving the unbinding of points from the original address and freeing the liquidity of the points themselves.

DAO and Community

A Bank for DAOs

Hackathon Subpage: https://devfolio.co/projects/a-bank-for-daos-baa1

Keywords: DAO Loan Support

Introduction: A Bank for DAOs aims to support small and medium-sized businesses such as restaurants, development studios, and hair salons, which are important components of the real economy but do not have access to venture capital support, do not engage in token financing, and cannot afford over-collateralized loans.

A Bank for DAOs hopes to provide simple, unsecured or low-collateral loans to small and medium-sized businesses willing to accept the DAO organizational form. During the ETH Denver event, A Bank for DAOs completed its first loan attempt and borrowed a loan from Metacartel's ETHos to provide to Open Source Observer, which chose its future RetroPGF income stream as collateral.

Sekai

Hackathon Subpage: https://devfolio.co/projects/sekai-4f6d

Keywords: Content Collaboration

Introduction: Sekai aims to revolutionize the traditional media model of content creation, allowing more people to participate in content creation.

Specifically, Sekai uses AI and Web3 to make content creation easier and more collaborative. Through the AI tools provided by Sekai, anyone can easily generate text, image, and audio content to bring their ideas to life. In addition, users can collectively decide the direction of the story, contribute ideas, and create content together, thereby enhancing the depth and engagement of content narration.

Sekai operates based on the Story Protocol and adopts a Social-Fi model inspired by Friend.tech, ensuring that all creators' contributions receive fair compensation, thus achieving a sustainable creator economy.

Tribuni

Hackathon Subpage: https://devfolio.co/projects/trust-impact-4bf0

Keywords: Ecological Benefits

Introduction: EBF Network of Trust provides a standardized ecological benefit discovery and verification mechanism.

Assessing the ecological benefits of various projects within the ecosystem is crucial for the ecosystem parent to decide how to implement funding or other support programs. However, to date, there has been no simple and standardized method to discover and verify the ecological benefits of projects.

EBFNT provides a standardized solution, allowing developers, investors, and stakeholders to make informed decisions when evaluating the impact of the projects they want to support.

Unbound Science

Hackathon Subpage: https://devfolio.co/projects/unbound-science-ac6f

Keywords: Research Funding

Introduction: Unbound Science aims to provide a new mechanism for research funding.

Currently, the process of applying for research funding is very poor, leading to many of the brightest minds and best technologies not receiving effective support. Unbound Science hopes to deploy a new funding economy system, allowing the public to decide the allocation of funds through voting to support the community's favorite proposals.

Unbound Science aims to build a research project showcase similar to "America's Got Talent," held multiple times a year to select more funding recipients. Unbound Science will initially support four categories of research: "energy," "air, water, and soil technology," "pollution/waste management," and "quantum research."

Identity, Privacy, and Security

ODIN

Hackathon Subpage: https://devfolio.co/projects/odin-6ddc

Keywords: Security

Introduction: ODIN is a Web3 guardian solution.

By integrating ODIN, Dapps can automatically pause their smart contracts before encountering malicious transactions that can execute destructive non-variable protocols (usually hacker attacks). This prevents potential financial losses for Dapp users, making Dapp operations more secure.

Oops!

Hackathon Subpage: https://devfolio.co/projects/oops-a44f

Keywords: Wallet Management Tool

Introduction: Oops! is a simple tool that allows users to quickly, thoroughly, and efficiently transfer all ERC-20 and ERC-721 tokens from one wallet address to another while maintaining their on-chain identity through proof of transfer. In case of unexpected address information leaks and other emergencies, Oops! can help users quickly mitigate risks.

HoneyPause

Hackathon Subpage: https://devfolio.co/projects/honeypause-9bca

Keywords: Security

Introduction: HoneyPause is a secure bounty protocol with a smart contract circuit breaker (used to pause contracts in emergencies).

HoneyPause actually consists of three contracts: the verifier contract, the pauser contract, and the payer contract. When a white-hat hacker discovers a major vulnerability in a protocol, they can submit a transaction (along with the vulnerable contract) through a private transaction pool to the HoneyPause contract.

The HoneyPause contract will then: run the vulnerability situation code provided by the white-hat hacker; verify if the protocol is affected by the vulnerability defined by the verifier contract; revoke the affected call frame, restore the protocol to a secure state; call the pauser contract to pause the protocol; and call the payer contract to pay the bounty to the white-hat hacker.
