Have you ever thought about a question: if an intelligent contract consumes false data, can the output still be the true result? It sounds like a brain teaser, but it is becoming the most critical weakness in the entire blockchain industry. Everyone is competing on TPS and building ecosystems, but few truly care about this fundamental issue—how to synchronize blockchain with the real world without being polluted by false information.

Blockchains are inherently "data blind." Stock prices, weather changes, logistics progress—these off-chain information are all unfamiliar to it. Traditional oracles try to act as this "messenger," but the problem is obvious: relying on a single data source is like giving all your house keys to a gatekeeper; if he becomes unreliable one day, the entire system collapses.

There is a different approach taken by a oracle network called APRO. It does not rely on a single authority but instead sets up a "data jury." It gathers information from dozens of independent data sources, verified through decentralized nodes, and finally makes a judgment using an AI risk control model. Only data that passes unanimously can be recorded on-chain—not just transferring information, but truly arbitrating facts.

Even more interesting is APRO's dual usage mode. Developers gain the first level of choice. In real-time push mode, market quotes, competition results, and trading signals can be actively pushed onto the chain within milliseconds, allowing DeFi liquidations and high-frequency trading to no longer worry about data delays causing unexpected losses. The on-demand pull mode is the opposite, calling data only when needed, saving costs on idle bandwidth. It’s like using water and electricity—pay as you go. Scenarios like insurance claims and property valuation can finally keep up with actual application needs.
