Recent progress in organ and tissue transplantation has significantly improved clinical outcomes; however, the effective management of transplant related data remains a major challenge due to fragmented and centralized information systems. Therefore, there are dangers of manipulation or loss of provenance, as well as poor traceability. This study maintains end-to-end integration of allograft data from the beginning of donor registration to the conclusion of the transplantation procedure. It is an Ethereum-based provenance framework with blockchain's immutability and distributed ledger capabilities. Six improved impact modules— automatic registration, verification, donor-recipient matching, donation approval, delivery tracking, and transplant M.Harini UG Scholar, Dept.of CSE, School of Computing, Mohan Babu University, Tirupati, A.P, India harinivalmiki2004@gmail.com Keywords — Blockchain Technology, Ethereum, Smart contracts, Allograft data management, Data provenance, Organ transplantation, Healthcare information, Distributed ledger maintenance, Data integrity, Traceability. I. INTRODUCTION confirmation—are used in this mechanism's implementation. By putting this process into practice in an Ethereum setting, the system is made safe, auditable, and privacy preserving. This system is helpful for exchanging data between tissue banks, hospitals, and government agencies. Experimental study demonstrates that this approach significantly increases transparency, lowers administrative delays and manual involvement, and offers more scalability with inexpensive maintenance. Additionally, their findings demonstrate how blockchain-driven provenance management can improve donor confidence and expedite the allograft transplantation procedure. This is a solid basis for the upkeep of healthcare data in the future.
