# APRO

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.

## Data Push

APRO's threshold-based data updates use a "Push-Based" model. In this model, decentralized independent node operators continuously aggregate and push data updates to the blockchain when specific price thresholds or heartbeat intervals are reached. This approach enhances blockchain scalability, supports a broader range of data products, and ensures timely updates.
