Blockchain-Based Diagnostic Certificate System with Privacy Protection

Blockchain represents a novel form of information technology application. It offers promising potential for future transactions and practical applications, particularly through the implementation of smart contracts. To address the issue of the time and expenses incurred by patients when obtaining a diagnosis certificate from various hospitals or clinics, blockchain technology is leveraged to generate diagnostic certificates via smart contracts on the Ethereum platform. This application harnesses blockchain features to ameliorate the identified problems, and it also presents solutions for the various operational processes involved in doctors recording diagnostic certificates and patients accessing their diagnostic records.
