Price Feeds

APRO Price Feeds utilize a "push" data source model, where multiple decentralized independent node operators aggregate data and push price updates continuously to the blockchain when price thresholds and heartbeat values are met. It aims to provide a greater number of price feed products, higher blockchain scalability, and faster update frequencies.

Price Feeds are widely used in various applications, covering DeFi protocols and smart contracts, providing highly trusted, real-time, and secure price data for emerging markets such as Bitcoin Layer 2, meeting the urgent need for accurate data in blockchain applications.

This process relies on multiple high-quality data transmission methods, leveraging the Hybrid node approach of oracles, multi-centralized network communication schemes, TVWAP price discovery mechanism, and self-managed multi-signature mechanism to aggregate price data in contracts, ensuring high-quality price data unaffected by vulnerabilities or oracle attackdifferent data feed categories and how to identify them.
