The longer you stay on the chain, the more you realize a harsh reality: DeFi project failures are not primarily due to contract vulnerabilities, but rather data issues.

Price feed delays lead to liquidation breaches. Fake random numbers destroy the fairness of games. Off-chain data tampering makes even the most sophisticated economic models ineffective. It seems that the oracle track has been thoroughly explored, but honestly, the core problem has never been truly solved.

This is why I’ve recently been researching APRO. It’s not some grand narrative that attracts me, but rather its approach to "data trustworthiness," which clearly leans towards engineering practice rather than pure marketing.

Traditional oracles have only two paths: increase node count to enhance security, or use economic incentives to prevent malicious behavior. Both sound reasonable, but in reality, they hit a ceiling. When it comes to complex scenarios like cross-chain settlements, real-world assets, game states, or off-chain activities, this logic begins to fail.

APRO asks a more fundamental question: since data itself can be contaminated, can the mechanism for verifying data be made more "intelligent"? The answer is integrating AI verification mechanisms into the oracle system. This is not just hype, but a very pragmatic technical choice. From a different perspective, it’s not just about "whether someone is quoting," but also about simultaneously assessing "whether this data has been historically reasonable."
