🔋2. Core Architecture and Innovations

2.1 Three-Dimensional Ecosystem Architecture

2.1.1 Hardware Layer: All-Scenario Data Collection Network

• Smart Device Matrix

  • Core Device: Modular Smart Ring

    • Basic Version: PPG heart rate / blood oxygen + body temperature sensors

    • Pro Version: Adds ECG (electrocardiogram) + blood pressure module

  • Open SDK: Compatible with third-party wearables such as Apple Watch and Fitbit; supports direct Bluetooth connection via mobile app

  • Edge Nodes: Partner merchants (pharmacies / gyms) deploy LoRa gateways to enhance offline data caching capability

• Technical Specifications

  • Battery Life: Basic version 120 hours / Pro version 72 hours (powered by nRF5340 low-power chip)

  • Data Collection Frequency:

    • Vital signs: real-time at 10Hz

    • Environmental data (temperature, humidity, PM2.5): 1Hz

  • Communication Protocols: BLE 5.3 + LoRa 1.0.3 (supports direct device connectivity within 2km)

2.1.2 Data Layer: Privacy-Enhanced Data Middleware

• Three-Layer Encryption System

  • Device Layer: Local biometric data hashed (SHA-256)

  • Transmission Layer: TLS 1.3 encryption + zero-knowledge proof (ZKP) for data anonymization

  • Storage Layer: IPFS distributed storage + on-chain indexing (data hashes stored on blockchain)

• Smart Data Contracts

  • Dynamic Authorization: Users can set data usage duration (7 days / 30 days / permanent) and scenarios (medical diagnosis / insurance underwriting / scientific research)

  • Revenue Distribution: 80% of data transaction revenue returned to users, 15% allocated to the ecosystem fund, 5% used for node rewards

2.1.3 Application Layer: Diversified Health Service Ecosystem

• Core Features for C-End Users

  • Health Dashboard: Real-time vital signs monitoring + AI health scoring (based on WHO standard model)

  • Data Marketplace: Anonymized data package auctions (supports stablecoin settlements in USDC/DAI)

  • Health Mall: Redeem GP points for health check-up packages / health food (in partnership with Meinian Health and Swisse)

• B-End Solutions

  • Insurance Actuarial: Provides real-time health data streams (with user authorization) to insurers to reduce adverse selection risk

  • Clinical Research: Offers pharmaceutical companies compliant subsets of disease-related data (e.g., exercise data from diabetic patients)

  • Urban Health: Provides governments with regional chronic disease trend analyses (data aggregation ≥ 1,000 people)

2.2 Key Innovative Technologies

2.2.1 Dynamic Data Weighting Algorithm Calculates data value based on a three-dimensional model: spatiotemporal, modality, and quality:

• Spatiotemporal Dimension: Data from rare scenarios (e.g., polar or high-altitude regions) weighted ×5

• Modality Dimension: ECG data valued at 3× compared to basic heart rate data

• Quality Dimension: Bonus of +20% GP for 72 hours of continuous effective data collection

2.2.2 Cross-Chain Data Gateway Supports bridging between Hyperledger Fabric and public blockchains (Ethereum/Solana), enabling compliant interactions between medical consortium chains and user-owned data sovereignty chains.
