Enhanced Blood Bank Transparency with Smart Contracts and Decentralized Storage on Ethereum

Abstract

This project introduces a blockchain-powered Blood Donation and Emergency Response System, which would provide blood donation, allocation, and emergency delivery secure, transparent and efficient manner for all donors, patients, blood banks, hospitals, ambulance drivers and system administrators involved. Without having to trust traditional records, the system uses blockchain-based digital identities so that every registration, every donation, request, and inventory update is permanent and easy to verify. Blood banks update their inventory on the blockchain for easy real-time tracking of blood supplies. When patients need blood, smart contracts verify availability and automatically execute the process or immediately notify hospitals and suitable donors of the extra units needed without requiring manual coordination. Hospitals can raise urgent requests, also logged onto the blockchain and smart contracts that notify eligible donors directly to their respective email address. System administrators monitor all activity through the admin portal, preventing data tampering and ensuring privacy and security are straightforward. In this manner, the decentralized storage of data, the creation of unchangeable records and the automatic execution of smart contracts reduce delay, fraud and complete traceability, thus dramatically improving the response to emergencies. Above all, this blockchain approach now helps in managing these very important operations of blood supply to make a reliable, tamperproof and location-based mechanism that saves lives where and when it matters.
