In the data layer of blockchain, oracles play a crucial role — they are the eyes that perceive external information in the on-chain world. However, as real-world assets are brought on-chain and the DeFi ecosystem becomes more complex, the security vulnerabilities and latency issues exposed by traditional oracles are becoming increasingly difficult to ignore.

The emergence of APRO offers a new approach to this dilemma. Its innovations are mainly reflected in two aspects.

First is the breakthrough in technical architecture. APRO adopts a dual-layer network structure, which maintains decentralization while significantly enhancing data processing capabilities. More notably, it introduces AI algorithms — no longer relying on cumbersome median filtering of nodes, but using machine learning to identify and clean abnormal data in real-time, inherently defending against price manipulation and similar attacks.

Another clever design is the flexible combination of push and pull modes. Popular assets use active push to ensure data real-time updates, while less active trading pairs support on-demand pull, which not only avoids unnecessary on-chain congestion but also greatly reduces Gas consumption of DApps during low activity periods.

Second is the extension of application scope. APRO not only handles the pricing of crypto assets but also supports on-chain mapping of diverse assets such as stocks, real estate, and gaming data. It currently covers over 40 mainstream public chains, and this broad compatibility makes it a strong contender in the RWA track.
