IV. PROPOSED ARCHITECTURE

This section provides a detailed exposition of our blockchain-based organ donation and transplantation solution. Figure 2 offers a glimpse into the system architecture of our proposed solution, highlighting the utilization of two smart contracts (SCs) — organ donation and organ transplantation. Accessible through a front-end decentralized application (DApp), participants can interact with the functions and events of these smart contracts, facilitated by an application program interface (API).

Each smart contract within the system is designed with unique functions, exclusively executable by pre- authorized participants. These participants, including doctors, hospital transplant team members, procurement organizers, organ matching organizers, a transporter, and a transplant surgeon, possess the privilege to access data stored on the blockchain. This access enables them to review transactions, logs, and events. The Organ Donation Smart Contract is tasked with creating a waiting list, accepting donors upon medical test approval, and facilitating auto-matching between donors and recipients. The Organ Transplantation Smart Contract oversees the transplant process, encompassing organ removal, transportation to the recipient, and organ implantation. All preceding phases are meticulously logged and stored on the ledger for revision and verification purposes. Furthermore, the system ensures authorization, confidentiality, and privacy by leveraging a private permissioned Ethereum blockchain.

The blockchain network serves as the foundational infrastructure for our proposed solution, acting as the permanent record keeper for transactions and events to ensure accountability and data provenance. To guarantee continuous accessibility, the developed smart contracts are deployed on the blockchain. During the testing phase, deploying them on the main network is not ideal. Instead, a local blockchain environment, a virtual machine (such as the JavaScript-based Virtual Machine), or a test network is utilized to test Ethereum-based smart contracts. Our smart contracts, developed using the REMIX IDE, are deployed on the JavaScript-based Virtual Machine, which runs an isolated Ethereum node in the browser, facilitating effective testing. Once thoroughly tested and verified, these smart contracts can be deployed on Ethereum's main net to assess their performance in a real blockchain environment. Importantly, the deterministic nature of the smart contracts ensures consistent outcomes regardless of the node performing the operation.
