Block-Dock
A Blockchain-Based Urban Grievance Redressal and Fund Management System
Demo
About
The problem it solves Block-Dock is a blockchain-based governance platform that enhances transparency, efficiency, and security in urban administrative processes. It solves key issues in grievance redressal, fund allocation, and project management by introducing role-based access control and immutable blockchain records. This ensures real-time tracking, fraud prevention, and accountability in municipal operations. User Interaction and Data Flow Users (Residents): File grievances and track their status. View approved projects and financial transactions. AdminHead (Municipality Head): Reviews grievances and updates their status (Accepted/Rejected). Requests funds from AdminGovt for project execution. Creates and manages projects (e.g., contractor details, deadlines). AdminGovt (Government Officer): Approves or rejects fund requests from AdminHead. Monitors grievance reports and project developments. Oversees financial transactions and fund utilization. Blockchain Data Flow: Grievances, fund transactions, and project updates are recorded on the blockchain. ERC20-based token system ensures secure, traceable fund transfers. MetaMask authentication secures login and role-based access. The project architecture and development process Smart Contracts: Implements role-based access using Solidity. ERC20-compatible tokens manage fund transfers. Immutable ledger ensures tamper-proof data storage. Frontend (React.js): Users interact via a clean, responsive UI. Wallet authentication via MetaMask. Backend (Node.js + Hardhat): Handles contract interactions. Stores user session data and handles API requests. Blockchain (Ethereum - Sepolia Testnet): Smart contracts deployed via Hardhat. Transactions and contract calls executed via Ethers.js. Product Integrations MetaMask – Wallet authentication and fund transfers. Ethers.js / Web3.js – Interacts with smart contracts. Hardhat – Smart contract deployment and testing. Ethereum Sepolia Testnet – Blockchain network for execution. Key differentiators and uniqueness of the project Transparent fund management: All transactions are publicly auditable. Decentralized grievance tracking: Eliminates bureaucratic delays and manipulation. Role-based access: Ensures that only authorized users can perform specific actions. Blockchain-powered accountability: Immutable records prevent corruption. Trade-offs and shortcuts while building Smart contract optimizations pending: Gas fee reductions and performance improvements planned. Limited AI automation: Future versions could integrate AI for grievance prioritization. Token standard: Currently ERC20; considering ERC721 for additional functionalities like NFT-based approvals. Additional Features Grievance tracking system on blockchain. Token-based fund allocation mechanism using ERC20. Admin dashboard for real-time monitoring of grievances and funds.
