The process of mutual respite generates a large flow of information. Existing mutual respite service information platforms are centrally managed. However, relying on a single point for data maintenance presents risks such as single point of failure, data loss, and security vulnerabilities. Additionally, since time point transactions are involved, the service content and time contributed by the service providers must be verified and recorded. This study integrates blockchain technology to achieve secure data storage, and the data and records stored on the chain are traceable.
