# Core Function Layer

1. **Task System:** Generates personalized tasks based on behavioral data collected from wearable devices (e.g., daily exercise goals, health check-ins). Upon task completion, smart contracts automatically distribute token rewards, enhancing user engagement and ecosystem stickiness.
2. **Health-to-Earn Incentive Mechanism:** Quantifies users’ health behaviors (e.g., running, workouts, sleep management) into contribution points, distributing ASTRA tokens proportionally, achieving “health management as mining.”
3. **Multi-Chain Wallet:** Integrated into wearable devices and companion apps, supporting storage, transfer, and exchange of multi-chain assets. Features biometric encryption unlock (fingerprint, heart rate) to ensure asset security.
4. **DApp Store:** Aggregates third-party Web3 applications within the ecosystem, covering health management, sports social networking, payment tools, insurance services, etc., providing users with a one-stop application experience.
