Organ Bank Based on Blockchain

The organ donation and transplant numbers differ in large numbers. The main reason for the difference is the number of donations that are performed compared to the number of organs being transplanted. A total of 7453 transplants were completed in the year 2020 whereas the number of patients who required transplants was over 2 lakhs. This significant difference is mainly due to the unawareness in the people of the importance of organ donation. On top of this, the black marketing of the organs is another major aspect which has led to an unorganized distribution of the organs. The existing system relies upon the central database system which includes the problems of reliability, immutability of the records and security of the data. The central database system lacks the validation methods for checking if the data has been modified or changed since they are the single source of information. This paper aims to solve the problem by using blockchain technology to store the records of the organs which can be tracked if any changes are occurred and stop the potential black marketing of the organs by verifying all the records that have been entered. The performance of the system will be measured based on the average response time of the system and the gas money used by the Ethereum Smart Contracts. We have found very low response times and lower cost of maintenance for the smart contacts, which shows that this approach can be used in the real-time organ transplant network.
