Abstract
In the current time bank system, problems such as difficult time token to circulate, difficult to trust data, and insecure data exist. In order to solve these problems, a design and implementation of a time bank system architecture based on blockchain technology is proposed. Firstly, analyze the business process of the time bank system and draw the use case diagram; then layer the overall architecture of the system: the application interface layer and the blockchain layer; then carry out a detailed architecture design, including the division of system functional modules: login registration module, publishing service requirements module, accepting service requirements module, managing service recipients, performing public service module, token management module, and drawing the main function flow chart of the system, and the design of the table in the server database of the system. The time bank system based on blockchain technology reduces the difficulty of time token flow, realizes data tamper-resistance through timestamp technology, distributed storage guarantees data security, and reduces the difficulty of time banking system operation.
