The Ethereum expansion hackathon “Scaling Ethereum” hosted by ETHGlobal officially announced the 12 winning projects last month, bringing more possibilities for the scalability of the Ethereum ecosystem. A total of 12 projects were awarded, most of which focused on the second-tier network ecosystem, providing developer tools, improving development efficiency, or enhancing user experience.
ETHGlobal is an organization dedicated to holding Ethereum hackathons, and its goal is to allow thousands of developers to join the Ethereum ecosystem. For example, the ” Hack Money ” hackathon was held last year, and Chain News selected and introduced some experimental DeFi projects.
The expansion of Ethereum has been the most important direction since last year’s DeFi Summer, so ETHGlobal also selected this topic in a timely manner and launched a special hackathon lasting nearly one month.
This event also received funding and support from the core expansion program teams in the industry, including Arbitrum, Optimism, StarkWare, zkSync, SKALE, The Graph, ZKSwap, Polygon, Uniswap, Ethereum Foundation, Celer, Torus, Loopring, Raiden, Connext et al. It can even be said that all teams related to the expansion plan are supporting this hackathon.
🦘Kangaroo: zkSync+Discord
Kangaroo (Kangaroo) is a Layer 2 wallet tool that can be used in Discord driven by zkSync. Its experience is similar to a bot in Discord.
🏛️Alexandria: StarkWare+Torus+ information verification
Alexandria is a decentralized application based on the STARKs technology in the zero-knowledge proof, which is used to verify some attributes of the user’s identity. The user does not need to disclose other information during use. The tool they use is Cairo developed by StarkWare. In user account management, they adopted the solution of the decentralized wallet Torus.
🐀The LabRats: Optimism+ forecast trading
RatTrace launched by The LabRats team is a multiplayer trading game where you can place bets based on whether the graph trend will rise or fall. The project uses Optimism’s second-tier network to sign and send each transaction, so that you don’t need to spend a lot of ETH as transaction gas fees.
🌞Zeneth: Use Flashbots to achieve gas-free access to the L2 network
The Zeneth team hopes to use Flashbots to allow ordinary Ethereum addresses (EOA) to achieve a user experience that can access the second-tier network without ETH through meta transaction.
The Ethereum network uses ETH as the gas fee, but this is not very friendly to users who only have other tokens, such as how to transfer 1000 DAI to the zkSync network without ETH.
Zeneth’s solution is to use the MEV solution Flashbots to directly send transactions to miners. Miners can package transactions with 0 Gas and use Zeneth’s integrated functions to exchange tokens for ETH to pay miners.
Flashbots is an open research organization initiated by five people in the blockchain industry. It aims to conduct research on the MEV problems faced by Ethereum and various smart contract public chains and implement solutions.
🌀HydroFile: IPFS+Ethereum
HydroFile is a Node.js code library that allows users to aggregate different versions and original data of the same file and store them on IPFS. In addition, multiple content identifiers (CIDs) can be stored in a variable Hypercore key. , Can be saved to Ethereum and accessed by any Ethereum program. Since the pointers in this solution only need to be stored in Ethereum once, the Gas fee can be reduced.
🐛Cairo Debugger: Cairo debugging tool
Cairo Debugger is a developer tool that can provide rich debugging capabilities for Cairo programs in text editors (VS Code, Emacs, Vim) commonly used by developers. Cairo is a Turing complete zero-knowledge proof platform launched by StarkWare.
⚒️Devolution: Optimism+DAO
Devolution is a decentralized autonomous organization (DAO) platform based on the second-tier network. Its features include the ability to maintain interoperability with the first-tier network, a customizable organizational structure, and a friendly user interface. The front end of the product will also be integrated. The user experience of the centralized wallet Torus.
🧩NFT Puzzle Thing: NFT+ game
NFT Puzzle Thing is a puzzle-solving game based on NFT. The first person who successfully solves the puzzle can get a rare NFT. In the second-tier scheme, they currently choose Matic, SKALE and Arbitrum, and the random number generation uses the Chainlink VRF scheme.
❌Exfil: Arbitrum+Tellor realizes quick withdrawal
Exfil is a protocol and SDK tool that provides quick withdrawal from the Layer 2 network. They currently use Arbitrum as a fast withdrawal network to realize the communication between the first and second layers, and at the same time use Tellor’s oracle to provide data.
🍧eth-sorbet: Lower the barriers for users to enter multiple L2 networks
Eth-sorbet (sorbet is a cold drink) is a tool for developers that can lower the barriers for users to enter the second-tier network. When the developer integrates eth-sorbet, a series of pages will appear on the website where the user visits the application, guiding the user to switch to the corresponding L2 network, otherwise the user may need to set the RPC and other configuration information of the corresponding network.
Currently the network supported by this tool includes: Arbitrum, Optimism, xDai, Matic, BSC, Avalanche, etc. The wallet supports MetaMask.
😎Flaunt: NFT combination tool
Flaunt (show off) provides NFT holders or collectors with a function that can synthesize new derivative assets from existing assets. In this way, they can create more limited editions or the concept of “mixing”, which can be gifted, Realize, or just collect.
At present, they support Arbitrum and SKALE’s two-tier expansion plan, using IPFS/Filecoin for storage, and Torus for wallets.
🌈Ray Tracing: Refer to Flashbots to implement MEV on other clients
Ray Tracing (ray tracing) provides infrastructure for the fields of MEV (miner extractable value), VEV (verifier extractable value), and SEV (pledger extractable value). Ray Tracing referred to Flashbots and implemented MEV and The Merge plug-ins on the Ethereum client Nethermind to achieve the acceptance and production of the most profitable MEV packages.
