APRO Oracle: Secure Off-Chain & On-Chain

APRO aims to construct a secure and trustworthy computing platform by combining off-chain computing with on-chain verification. This approach extends data access and computing capabilities, providing customized computing logic services for DApp businesses. We continually refine and optimize the platform to offer users superior services and experiences, collectively advancing the development and application of blockchain technology.

APRO Price Feeds

APRO Price Feeds offer a solution that includes a "push" data source model, where multiple decentralized independent node operators aggregate data and push price updates continuously to the blockchain when specific price thresholds and heartbeat values are met. This model is designed to support a broader range of price feed products, enhance blockchain scalability, and enable 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 attack different data feed categories and how to identify them.
