Infrastructure Layer

• DePIN Physical Network: A distributed network of physical nodes composed of Astra-certified wearable devices (e.g., AstraWatch smartwatches and smart bands). Nodes support ecosystem operations by providing device computing power and data collection capabilities, earning token incentives in return.

• Blockchain Infrastructure: Built on a multi-chain compatible architecture, supporting Ethereum, Polygon, Avalanche, and other public chains. Sidechains and cross-chain bridges enable interoperability of data and assets, ensuring ecosystem security, scalability, and operability.

• Distributed Storage Network: A decentralized storage system based on IPFS/Filecoin, encrypting users’ health data and core ecosystem data to prevent risks associated with centralized storage.
