GrantChain: Decentralized Participatory Granting Platform using DAO

Overview

GrantChain is a decentralized platform that redefines the grant awarding process by leveraging blockchain technology and decentralized governance. It ensures transparency, inclusivity, and community-driven decision-making, enabling government officials to submit grant projects on-chain and allowing participants to submit their proposals by staking tokens. The selection process is governed by a Voting DAO, where stakeholders use governance tokens to vote on the proposals.

Key Components

1. Frontend

• Framework: React.js with Material UI
• Description: The frontend provides a user-friendly interface where government officials can submit grant projects, and participants can submit proposals and vote. The UI is responsive and built to offer a seamless user experience.

2. Smart Contracts

• GovernanceToken.sol: ERC20 token used for voting within the DAO.
• ProjectToken.sol: ERC20 token used for staking by participants submitting proposals.
• StakeHolderManager.sol: Manages the addition and removal of stakeholders who can vote.
• ProjectGrant.sol: Core contract for managing grant projects, proposals, voting, and fund release.

3. Backend

• Framework: Express.js
• Database: MySQL
• Description: The backend is responsible for indexing blockchain contract events, subscribing to them, and writing the relevant data to a MySQL database. It also provides RESTful API endpoints for interacting with the frontend and other services.

4. Blockchain Integration

• Blockchain Node: Connects the backend to the Ethereum blockchain.
• Smart Contracts: Deployed on the Ethereum blockchain to manage the grant projects, proposals, and voting.

Features

• Decentralized Governance: Community-driven voting using a DAO to decide on grant awards.
• Staking Mechanism: Participants stake ProjectTokens to submit proposals, ensuring commitment.
• Transparent Fund Release: Grants are released to the winning proposals based on community voting.
• Event Indexing: Backend subscribes to blockchain events, ensuring up-to-date data in the database.
• User-friendly Interface: The frontend is designed to be intuitive and accessible to all users, regardless of their technical expertise.

Deployment

Prerequisites

• Node.js
• MySQL
• Klaytn Network
• Truffle or Hardhat for contract deployment

Installation Steps

1. Clone the repository:

   git clone https://github.com/khajievN/vic-hackathon.git

2. Install frontend dependencies:

   cd frontend
   npm install

3. Install backend dependencies:

   cd backend
   npm install

4. Deploy Smart Contracts:

   • Use Truffle or Hardhat to deploy the smart contracts on an Ethereum network.
   • Update the contract addresses in both the frontend and backend configurations.

5. Run the backend:

   cd backend
   npm start

6. Run the frontend:

   cd frontend
   npm start

   The frontend should now be accessible at http://localhost:3000.
