A Blockchain-Based Framework for Secure and Transparent Crowdfunding

Abstract

Traditional crowdfunding platforms rely on centralized servers to manage user funds and transaction records, making them vulnerable to data manipulation, lack of transparency, and misuse of funds. To address these challenges, this project presents a Trusted Crowdfunding System based on Blockchain Technology, which replaces centralized control with a decentralized and tamper-resistant infrastructure. Contributors often have limited visibility into how their money is utilized, and any internal compromise of the server can lead to loss or alteration of critical financial information. Smart contracts developed using Solidity manage core functionalities such as user registration, transaction recording, fund transfers, and account balance updates. Once deployed on the blockchain, these contracts ensure that all operations are transparent, verifiable, and resistant to unauthorized modification. The proposed system leverages the Ethereum blockchain to securely store user and transaction data in the form of immutable blocks linked through cryptographic hash values. The system supports essential modules including user signup and login, adding funds to a blockchain wallet, linking bank accounts, transferring funds to other blockchain users, and viewing detailed transaction statements. Every financial operation is permanently recorded on the blockchain, allowing users to track fund usage and transaction history with full accountability. A web-based application built using the Django framework enables users to interact with the blockchain seamlessly. This approach minimizes the risk of fund misuse, eliminates single points of failure, and encourages greater user confidence in digital crowdfunding ecosystems. By integrating blockchain decentralization with a user-friendly interface, the proposed crowdfunding platform enhances trust, security, and transparency
