Following the just-concluded EthCC7, ETHGlobal also held the ETHGlobal Brussels hackathon in Brussels from July 12 to 14, with a total of 355 projects participating and a prize of up to $475,000.

On July 14, 2024, ETHGlobal Brussels announced 10 winners. The ten projects are: BananaBets, Cook some hooks, Zarathustra, Tap Ether, Oh Snap!, Omma Cash, Piggy Wallet, AdFHE, Ephi, Individuum.

Here is a brief introduction to the ten winning projects:

BananaBets

A betting platform where ETHGlobal Brussels attendees can predict the winners of the hackathon based on the presentation data and easily join using their NFC wristbands, and betting transactions are directly signed by their NFC private keys.

Cook Some Hooks

A tool that allows users to easily create and deploy Uniswap v4 hooks using generative AI. Users can choose their favorite DeFi dApp (such as Uniswap or PancakeSwap), select the currency pair they want to create a pool for, and then utilize the LLM model to generate hook functions. The generated hook can then be deployed on any EVM-compatible chain. The project aims to simplify the process of creating and deploying custom v4 hooks, lowering the barrier for non-technical users and developers so that they can learn faster and use it as a bootstrap for more complex hooks.

Zarathustra

A distributed, modular, permissionless artificial intelligence designed to be a completely open reasoning network. Zarathustra consists of three main participants: users, routers, and models. These participants are coordinated through smart contracts. Anyone can join and play any of the roles without permission.

Users interact with the frontend to submit queries, such as "How many r's are there in the word strawberry?". They submit the query to the smart contract, which processes and broadcasts an event emission. This event emission is received by the "router". The router is a high-level large language model responsible for analyzing the query to determine its nature and the required task. Based on the analysis, the router dispatches the task to the appropriate specialized model.

Tap Ether

Tap Ether is a simple app that allows you to send crypto assets to others by simply tapping your phone. It is built with React Native and uses NFC technology to allow devices to communicate when they are close to each other. With Tap Ether, the person receiving the crypto asset needs to enter their wallet address or connect their wallet. The sender then brings their phone close to the receiver's phone to connect their wallet. The receiver specifies the amount, then requests a signature and waits for the transaction to be signed. This process makes it very fast and secure to transfer cryptocurrencies by just tapping the phone using NFC.

Oh Snap!

Provides background information about smart contracts before transactions, using community voting logic inspired by Vitalik's blog about the X Community Notes algorithm.

Omma Cash

Allows users to send and receive cryptocurrencies using WhatsApp chat and natural language prompts, so even grandmothers can use it.

All user experience takes place through WhatsApp chat, while all technology and on-chain transactions run in the background so that users can seamlessly send and receive funds, whether in crypto or fiat.

Piggy Wallet

A cryptocurrency savings app for children, including time-locked savings, automatic USDC exchange, goals, task bounties, AI coaches, and parental controls.

AdFHE

A personalized advertising protocol based on fully homomorphic encryption (FHE). AdFHE uses fully homomorphic encryption (FHE) to achieve personalized advertising. FHE is a technology that can perform calculations on encrypted data without decryption. This means that AdFHE can safely analyze user characteristics and preferences, ensuring privacy protection throughout the process. Much like how leading search engines and social media platforms deliver customized content without revealing personal information, AdFHE employs a recommendation algorithm. The algorithm processes encrypted user data, enabling platforms to deliver targeted ads while protecting individual search history and personal information. By prioritizing privacy and security through FHE, AdFHE sets a new standard for personalized advertising, ensuring that users receive relevant ads without sacrificing confidentiality.

Ephi

Blinks application. Inspired by Solana Actions and Blinks and Forecaster Frames, Ephi Blink extends the web3 ecosystem to any web2 environment.

Ephi creates a browser extension to achieve this that supports embedding a mini context window anywhere on the web. The Phi plugin is able to interpret special bLINKs anywhere on the web and render a dynamic html context window. The html and javascript code is retrieved from the IPFS protocol. When an action within the context window is clicked, the user will be prompted to sign a transaction in their wallet, and the state of the context window will change accordingly upon success. Ephi has also built a custom Ephi Blink builder where anyone can choose from pre-built presets or create brand new ones for any use case you can think of.

At the ETHGlobal Brussels hackathon, Epi built three different Ephi Blink examples. 1. A bridge Blink that uses the Chainlink CCIP protocol to bridge USDC from one chain to another. 2. A donation Blink where users can donate to a cause. 3. A Blink with built-in blink publisher invite transactions, enabling true web3 consortium blinks.

Individuum

A network task automation marketplace that guarantees that tasks are completed according to the required specifications and ensures transparent and secure payments.

Customers can list their network tasks in the Individuum marketplace or delegate them to a party they want to share the task with. This involves providing clear instructions, outlining specific requirements and setting a fixed price for each task. The platform then matches the task with workers who can complete it efficiently. One of the main advantages of Individuum is that it guarantees the completion of the set requirements. Throughout the transaction, both parties will be protected by Individuum's integrated payment system. The person who owns the list must lock the number of tokens they specify in the list. Once the task is automatically verified, the workers who meet the task requirements will automatically receive the tokens. With this system, neither party can cheat.
