7. Technical Architecture

BrushO is composed of the following modules:

• Smart Devices: These include oral sensors (tooth monitoring sensors/oral microbiome sensors), oral hygiene monitors, oral scanners, and other smart devices.

• Users: By registering and linking devices, users can claim ownership of the oral data uploaded by the smart devices. Users hold the ownership of their data and authorize its usage.

• BrushO Network: This includes functions such as device management, identity services, data collection and verification, incentive modules, data distribution, and usage. It ensures the authenticity and high quality of the data, matches data with the needs of data users, and calculates and distributes incentives based on the results of data uploads and usage.

• Data Usage Scenarios: These include a variety of applications such as AI training, dental healthcare, and dental insurance.

• Solana Blockchain Network: This is used for issuing NFTs, distributing and claiming token rewards, and implementing future DAO governance functions.

• IPFS Blockchain Network: To ensure long-term data storage and reliability, data will be encrypted and uploaded to IPFS distributed storage servers, allowing users to access their data at any time through IPFS.

The data flow process in the BrushO ecosystem is as follows:

Users register and link their devices to obtain an identity credential NFT on the BrushO Network. The NFT uniquely identifies each user, facilitating data ownership verification, incentive calculation, and distribution. Oral data generated from daily use of the smart oral devices is uploaded to the BrushO Network. The network processes the data through anonymization, ownership verification, and training, then matches it with the needs of data usage scenarios. Upon user authorization, the data is distributed to the appropriate parties. Based on the data generation and usage process, the BrushO Network's incentive module calculates rewards, generates them, and uploads them to the Solana blockchain for users to claim. The BrushO Network does not permanently store data; instead, user data is uploaded to the IPFS distributed storage servers for permanent encrypted storage, ensuring data privacy and security.
