BLOODLINK: Revolutionizing Blood Donation using Blockchain and IoT

Blood donation plays a vital role in healthcare, supporting life-saving treatments such as surgeries, organ transplants, and emergency interventions, but traditional centralized blood management systems have for a long period been characterized by security weaknesses, inefficiencies, and challenges in tracking blood units. The mobile application sets itself as a novel integration of blockchain, IoT, and RFID technology in blood donation management systems. The solution proposed will attempt to tackle the more than pressing concerns regarding its traceability and prevention of fraud. Strengths of the system would entail, among others, real-time, tamper-proof tracking, decentralized storage, and automated donor verification using smart contracts. The blockchain keeps a tamper-evident decentralized system that allows the recording of donor registration, blood collection, and safe storage as well as transfusions, but one that makes data tampering virtually impossible. Various processes are integrated into this system, which includes, but is not limited to, verifying donors' eligibility, managing inventories, and processing requests in hospitals, highly reducing delays. IoT-enabled sensors provide an uninterrupted way of tracking and documenting variables in storage and transportation to keep blood integrity throughout. This combination of RFID with its data on the blockchain ensures real-time monitoring of blood unit movement, which significantly reduces errors and unauthorized access. The mobile-friendly app, which connects donors with blood banks and hospitals seamlessly, provides an efficient way to verify the donor history and supply of available blood in real time. This better traceability of blood donation increases fraud prevention and automation, facilitates program adherence, and sets the stage for building a network of blood donations that is safer and more efficient.
