The Blockchain-Based Blood Donation Management System is a revolutionary platform that leverages Ethereum blockchain technology to create a transparent, secure, and efficient ecosystem for blood donation and transplantation management. This system addresses critical challenges in traditional blood donation systems including lack of transparency, inefficient donor-patient matching, data tampering risks, and limited accessibility to donation history. By implementing smart contracts on the Ethereum network using Solidity, the system ensures immutable storage of medical records while maintaining patient privacy through cryptographic techniques. The platform facilitates seamless interaction between hospitals, patients, and blood donors through a Django-based web interface with MySQL backend, enabling real-time tracking of donation requests, automated matching based on medical compatibility, and secure record-keeping of transplantation procedures. This innovative approach significantly reduces matching time, eliminates fraudulent records, and creates a trustworthy environment for life-saving blood donation processes while maintaining complete audit trails of all medical transactions.
