Having been in this industry for so many years, I can always see through some of the essential truths. We've been working for over a decade, constantly optimizing TPS, reducing transaction fees, and researching scalability solutions for various public chains. It seems that making the chain faster and cheaper can solve all problems. But reality often hits hard: many seemingly promising projects end up quietly dying, and the cause is often not technical failure but being closed off.

Think about lending protocols, derivatives trading, blockchain games, and now the hot RWA—real-world asset tokenization. Can these things be disconnected from external information? No. Price movements, sports results, weather data, flight information—none can be missing. But the chain itself is an information island, completely cut off from the outside world. At this point, oracles become the only lifeline, responsible for bringing external data in real-time. If this line is unstable, even the most perfectly decentralized system can only become a self-repeating game, collapsing at the slightest touch.

Because of this, I have paid special attention to the oracle track in the past two years. I can feel the industry's awakening, realizing that price feeds alone are far from enough. The market's complexity has increased. Take perpetual contracts trading as an example: knowing only the current ETH price is simply not enough. You also need real-time volatility, funding rate data, precise liquidation prices, liquidity depth on other chains, and even Federal Reserve policy trends—these multi-dimensional pieces of information are necessary to support a reliable trading system. Traditional oracles are just carriers, moving data from point A to point B, with low efficiency and slow response, unable to keep up with market rhythm.

The emergence of APRO precisely meets this demand. It supports both data push and data pull modes, not blindly pursuing flexibility, but seriously addressing the differentiated data supply needs of different scenarios—this is a more mature approach.
