Abstract
Tracking the shipment of blood is difficult, and violation of maintaining critical parameters leads to wastage and spoilage. IoT sensors can be used to monitor temperature, pressure, humidity, exposed to light, broken seal, etc. In our work, we implemented and tested an Ethereum based smart contract in solidity platform. Although several research works have been carried out in the blood bank inventory system, few of them focus on its security, transparency, and traceability. Health record sharing without modification is essential. Blockchain-based blood bank systems can resolve the need for individuals to access, trace, manage, and share their health and blood-related information which is immutable. Blood traceability can increase the availability systems to blood bank system and determines the number of quantities to transport from cities to a rural area. Delay in availability, results in delay in surgery or may lead to death. The blockchain-based system is a confidential environment which acts as a communication hub between donors, doctors, testing labs, and recipients or patients. To address these issues, we have designed a blockchain-based solution for the blood bank system.
