Crowd Funding Android App Using Block Chain

This Crowdfunding has emerged as a vital financial support system for students in need of educational funding. However, traditional crowdfunding platforms suffer from lack of transparency, security concerns, and high transaction fees, which reduce donor confidence. To address these issues, this project proposes a Blockchain-Based Crowdfunding Platform that leverages SHA-256 hashing with a Hash Map-based blockchain to ensure tamper-proof, transparent, and decentralized transactions. The platform is implemented as an Android application integrated with Firebase for real-time data management. Students can create fundraising campaigns, while donors can contribute securely, with all transactions hashed and linked to previous transactions, ensuring data integrity and immutability. The platform also includes user authentication, a donation tracking system, document verification, and an intuitive dashboard. This approach provides a secure and verifiable crowdfunding ecosystem, reducing fraud and enhancing donor trust.
