How many times have you truly blown your positions in decentralized finance due to misjudging the direction? Honestly, most of the disasters I've seen are not like that. The real knives are often in the dark—those unseen data traps.

At 3 a.m., your position is mysteriously pierced by a strange K-line; the assets you collateralized suddenly get marked down, and the system automatically liquidates; a contract you predicted correctly, but on-chain data shows the opposite result... These magical scenes are usually orchestrated by the same black hand—the one feeding data to the smart contract.

Blockchain has a fatal flaw: it does the accounting perfectly but knows nothing about the external world. Price fluctuations, game results, market data... all rely on oracles as the "middlemen" to relay information. Once this information channel is poisoned, even the most perfect contract logic can't save you.

APRO has identified this pain point. It doesn't dream of a hundredfold coin; it just wants to do one thing—fix the "disease" of on-chain data.

How to fix it? It follows three stages: First stage, AI performs preliminary detection. Incoming data is first scanned by AI—not to make it tell stories, but to act as a "detector"—identifying abnormal fluctuations (50% price change within a second), contradictions among multi-source data, and suspicious witch attack patterns. Bad data is intercepted before it even gets on-chain.

Second stage, independent validation by a node group. Data approved by AI must also pass through a "review committee" composed of staked nodes. Each node verifies independently, and only after reaching consensus can it be finally recorded on-chain. With real stakes involved, no one dares to mess around.

Third stage—this is the most ruthless—on-chain transparent backtracking. All data flow processes are recorded on-chain. Once an anomaly occurs, anyone with dirty hands will be exposed by a simple ledger review.

In short, it's a multi-layer defense: AI detection → node consensus → on-chain traceability. With this setup, anyone trying to profit from data poisoning will have to think twice.
