# 3.3 Oracle Network & Data Security

A multi-source redundant oracle system ensures data accuracy and reliability:

* **Primary Oracle:** Chainlink (aggregated pricing from 30+ nodes)
* **Backup Oracles:** Band Protocol + Pyth Network (auto-switch triggered when price deviation >1%)
* **Data Encryption:** Real-world asset (RWA) data undergoes zero-knowledge proof processing, with only hashed values disclosed on-chain
