Smart contracts are powerful and can execute rules perfectly. But they have a fatal flaw—they cannot see the outside world. That’s why infrastructure like oracles is becoming increasingly important. APRO is such a player, but it’s not just about transporting data; it truly achieves comprehensive fact-checking: transforming the chaotic signals from the real world into trustworthy on-chain events through off-chain verification and AI logic processing.

In simple terms, if you are building something beyond basic token exchanges—such as prediction markets, insurance protocols, or derivative contracts—this kind of "pipeline" infrastructure is what you need. Its workflow isn’t that complicated: collecting information from multiple data sources, running a set of verification logic and AI models off-chain to filter out junk data, then packaging and sending reliable signals to the chain. The entire process is about one thing—ensuring that on-chain decisions are based on real, verified data.

What does this mean for the Web3 ecosystem? It means more complex application scenarios become feasible. From risk pricing to automated execution, oracles are becoming a key component of DeFi reliability.
