While many Web3 projects are still struggling with the difficulty of technology implementation, Astra Network has already integrated blockchain into smartwatches with hardcore technologies such as multi-chain compatible architecture, zero-knowledge proofs, and DePIN distributed node networks. This device, named Astra Watch, not only measures heart rate and tracks exercise, but also securely stores assets and monetizes health data. Behind all of this lies a technology system specifically designed for wearable scenarios.

The first breakthrough against traditional bottlenecks is Astra’s DePIN distributed physical network technology. Unlike centralized platforms monopolizing device data, each Astra Watch becomes an ecosystem node: the built-in blockchain chip encrypts and collects exercise and sleep data in real time, then synchronizes it to the distributed storage network (IPFS/Filecoin) through low-power communication protocols (LoRa + Bluetooth 5.0). While contributing data, users earn ASTRA token rewards based on data quality + node activity—meaning every run you take is mining for your node. The technology directly transforms healthy behavior into income.

The solution to the conflict between data privacy and monetization lies in zero-knowledge proof (ZKP) technology. In the traditional model, if you want an insurance company to lower your premium using health data, you must expose raw data. Astra’s health data gateway, however, uses ZKP to desensitize data: for example, proving that your average daily exercise exceeded 1 hour in the past 30 days, without providing specific routes or heart rate fluctuations. The insurance company can lower the premium with effective proof, while the user’s data privacy remains intact. Feedback from beta users: after authorizing data to insurance companies, premiums dropped by 30%, while authorization records can be viewed in real time on the mobile phone, providing strong reassurance.

The multi-chain compatible architecture makes Web3 experiences smoother. Astra Watch’s built-in wallet supports mainstream chains such as Ethereum, Polygon, and Avalanche, enabling cross-chain asset interoperability via bridge technology. Your USDT on Ethereum and NFT on Polygon can be managed on the watch without switching apps. During payments, biometric encryption (heart rate + fingerprint) automatically completes transaction signing—avoiding private key loss risk while enabling “raise your hand to pay” convenience. This is backed by Astra’s deep optimization of multi-chain wallet interaction logic.

More importantly, the technology also considers practicality: Astra Watch’s custom blockchain chip reduces computing power consumption to 1/5 of traditional chips. Combined with an intelligent battery algorithm, it achieves 14-day battery life on a full charge—so users don’t need daily charging while continuously participating in the ecosystem.

Today, these technologies are no longer just concepts on a white paper, but tangible experiences you can wear on your wrist. Astra Watch smartwatches are now available for presale. As Web3 technology evolves from complex code into everyday tools, early adopters are capturing both health and wealth dividends.
