APRO Oracle: Secure Off-Chain & On-Chain

APRO is building a secure platform by combining off-chain processing with on-chain verification, extending both data access and computational capabilities. This forms the foundation of APRO Data Service, improving data accuracy and efficiency while offering the flexibility to create custom solutions tailored to the specific needs of DApp businesses.

APRO Data Service supports two data models—Data Push and Data Pull—that deliver real-time Price Feeds and other essential data services, ensuring comprehensive support for all DApp business scenarios. Currently, we support 161 Price Feed services across 15 major blockchain networks:

  • Data Push: APRO Data Push uses a "Push-Based" data model to deliver Price Feed services. Decentralized independent node operators continuously gather and push data updates to the blockchain when certain price thresholds or time intervals are met. This method improves blockchain scalability, supports various data products, and provides timely updates.

  • Data Pull: APRO Data Pull uses a "Pull-Based" data model to deliver real-time Price Feed services to dApps. It is designed for on-demand access, high-frequency updates, low latency, and cost-effective integration. This flexible and efficient model is ideal for DeFi protocols, decentralized exchanges, and other applications needing rapid, dynamic data without ongoing on-chain costs.

We continually refine and optimize our platform to deliver enhanced services and experiences, driving forward the development and application of blockchain technology.
