Everyone is focused on throughput and Gas fees, but I am more concerned about something that is often overlooked: whether the data your contract depends on is truly accurate at critical moments.

This kind of failure is silent, but once something goes wrong, it feels terrible—liquidation seems completely compliant from the code logic perspective, but users feel cheated because the data fed by the price oracle has issues; the random number results in the game can be calculated in advance, and the winners are actually those who understand the code.

APRO is aimed at addressing this practical pain point: external data must be trustworthy enough for smart contracts to confidently make decisions based on it. It's not just about putting data on the blockchain, but rather solving the authenticity issues of the data itself. This is the invisible battlefield of blockchain infrastructure.
