Organ donation and transplantation are vital parts of the diverse healthcare sector. Success in these procedures primarily hinges on the satisfactory performance of the organ before its transplantation, which can be guaranteed only if the organ details are transparent and traceable throughout the period between its extraction and implantation in the patient's body. The main concern is the centralized architecture of current organ transplantation systems, limiting patient access to critical information about the allocated organ's status during transportation. Furthermore, the blockchain-based decentralized models within this domain are not economically viable due to their high gas consumption. It is the need of the hour to establish a cost-efficient, decentralized, secure, and reliable framework that instills trust in patients, assuring them that the organ intended for implantation into their body remains uncontaminated and unaffected by variations in temperature and humidity during transit. Additionally, the framework must secure the container holding the organ to prevent any opening, tilting, or falling while in transit. The paper proposes a framework of decentralized application connecting Internet of Things sensors integrated within the organ container with the Ethereum blockchain smart contracts, consuming approximately 0.0001099004 Ether; and utilizing approximately 34,830 gas value. This system guarantees and verifies the cost-efficient and safe transportation of organs. Smart contracts, through the decentralized application, notify the authorized stakeholders in the event of any violations or issues with the organs. The important benefit of this entire method is that it allows patients, relatives, and even doctors to receive real-time information on the condition and status of the organ during its transit, providing them with complete transparency, which is crucial considering the substantial financial investment associated with obtaining an organ. The paper also compares the proposed framework with the existing approaches within the domain of IoT-based transportation with blockchain integration and observes that the gas value and Ether consumption of the proposed method have shown significant improvements over existing approaches.
