Organ donation is a noble act providing possibility of new life and improves health plus well-being of society. There is an increasing number of patients who dies due to lack of transplantable organs. Blockchain technology can be a key solution for the needs by enabling transparency, immutability, dependability, and auditable computing within the system via utilizing decentralized network of peers and ledger having provable time-stamped proof of owning and generation. Implementing blockchain technology in the organ donation system can improve data analytics, transparency, and security. Consequently, the blockchain-enabled organ donation system-the DONOCHAIN will become a platform for the donor as well as the receiver to securely manage the information they are sharing with transparency, immutability, distributed nature, and reliability. Eliminating inefficiency will result in a decrease in cost by performing transactions through smart contracts, between parties without centralized control. Using smart contracts will help in authentication of the users to make the system more trustworthy for both the donor and receiver. Modern analytics maximizes allocation and use, enabling optimal organ matching. While regulatory requirements are enforced by automated compliance systems, real-time monitoring ensures timely response. Smart transplants change organ donation by providing improved patient outcomes, more efficacy, and global accessibility.
