The storage and processing of prescriptions are crucial aspects in ensuring the security and accuracy of medical information. Existing prescription processing systems are often vulnerable to forgery and cyber-attacks. Blockchain technology offers a solution to create a more secure and reliable data storage system. In this study, blockchain technology is implemented using the Hyperledger Fabric platform to develop a prescription processing system. Blockchain, with its decentralized and immutable characteristics, enables the storage of prescription data in a ledger that cannot be altered. Hyperledger Fabric was chosen for its higher performance and smart contract features, which can replace the need for centralized parties in the prescription processing workflow. This research resulted in a blockchain-based application prototype designed to enhance security and integrity in managing prescriptions. System testing showed that the developed prototype successfully improved the security and integrity of prescription data. The system ensures that each transaction is accurately recorded in an immutable ledger, in line with the defined functional requirements. However, non-functional testing related to data integrity could not be fully conducted, as direct modifications to LevelDB are technically not possible in Hyperledger Fabric. Such actions bypass the consensus mechanism and could pose significant risks, such as data corruption, ledger inconsistencies, and threats to blockchain security and integrity.
