Real-life Blockchain Application

a. THE9 mileage operation structure

To facilitate real-life application of blockchain for the integrated mileage operation, we utilize the mileage user app linked to the KIOSK and wallet. Information related to earning and usage is stored on the blockchain. However, there are some disadvantages to this approach. Direct earning and usage between KIOSK and wallet can be slow, causing inconvenience for real-life use. Additionally, blockchain network costs are incurred for each use.

b. Technological Complement for Real-life Application

To address the disadvantages mentioned above, we implement a mileage token transaction structure between the KIOSK, mileage user app, and virtual asset exchange user wallet for earning and using mileage tokens. By transferring mileage token accumulation and usage information between the user's wallet and the foundation's wallet through the linked virtual asset exchange, we resolve the issue of slow transmission speed and reduce network usage costs for real-life use. However, a drawback of this approach is that the internal network of the exchange may not store mileage token accumulation and usage information on the blockchain network, leading to missing data.

c. Blockchain Technology Supplementation for Missing Information

To compensate for the missing information related to mileage token earning and usage recorded on the blockchain, a separate roll-up server is created to store this information on the blockchain using a sidechain method. By storing earning and usage-related data on the blockchain network through this separate server, we can record and verify the accurate mileage payment and usage quantities through cross-verification, thereby ensuring data integrity and accuracy. This supplementation helps to overcome the limitations of the previous approaches and enhances the reliability and efficiency of the THE9 mileage operation in real-life applications.
