Abstract: The proposed blockchain-based organ donation and transplantation system enhances efficiency, security, and transparency in managing organ donations. Traditional organ donation frameworks depend on centralized databases, which are prone to unauthorized access, data breaches, and inefficiencies in organ allocation. To overcome these challenges, this system leverages a private Ethereum blockchain, ensuring secure, immutable, and decentralized management of donor and recipient records. Smart contracts, developed using Solidity, automate key processes such as donor registration, recipient matching, and organ allocation. By eliminating manual intervention, the system ensures fairness and accuracy. Medical institutions can securely register donors and recipients, with every transaction permanently recorded on a tamper-proof ledger, promoting transparency. Once a suitable match is identified, real-time notifications alert all relevant stakeholders, enabling recipients to track their organ request status through a hospital-issued unique identification number. The platform employs advanced cryptographic methods and role-based access controls to safeguard sensitive medical data, restricting access to authorized personnel only. Additionally, integrated data visualization tools offer insights into organ donation patterns, aiding policymakers in making informed decisions.By incorporating blockchain technology and smart contracts, this system introduces a decentralized, trust-driven approach to organ donation, ensuring data integrity, optimizing efficiency, and reinforcing security. It represents a transformative advancement in medical technology, setting a new benchmark for ethical and transparent organ transplantation processes.
