Budget Tracking using Blockchain

Abstract

In the modern digital age, personal and organizational finance management has become increasingly complex and vulnerable to data tampering, lack of transparency, and security breaches. Traditional budgeting systems rely heavily on centralized databases, making them prone to manipulation and cyber-attacks. To overcome these challenges, this project proposes a Blockchain-based Budget Tracking System that ensures secure, transparent, and tamper-proof financial record-keeping. The system leverages the decentralized and immutable nature of blockchain to store and manage income and expense transactions. Through smart contracts, users can add, categorize, and retrieve financial data, which is permanently recorded on the blockchain. The application provides a user-friendly interface integrated with crypto wallets (e.g., MetaMask) to authenticate users and facilitate seamless interactions with the blockchain. Key features include expense/income categorization, transaction history tracking, budget alerts, and visual analytics. By decentralizing financial tracking, the system promotes trust, accountability, and auditability, making it suitable for individuals, families, NGOs, and small businesses. This innovative approach not only enhances security but also empowers users with full control over their financial data. This project demonstrates the potential of blockchain technology in transforming conventional budgeting systems into transparent and secure decentralized applications.
