The balance on the phone screen is moving every day. Earning $27 daily from 50,000 USDT, which at the current exchange rate amounts to an extra 5,400 yuan per month—when I saw this number, I was stunned for a moment because this amount of money is already close to many people's full monthly salary.

Honestly, the feeling of "money making money" is indeed tempting. But upon closer reflection, I started to feel uneasy: who is actually bearing the cost of that extra 180 yuan every day? What is the logic behind this?

So I began to dig into the protocol white paper, tracking the flow of funds. The more I looked, the more I uncovered a bigger problem. The "passive income" we talk about is essentially trusting a bunch of data we can't verify—where does the interest rate come from, how good is the collateral, where are the protocol risks... If these basic data are manipulated or distorted, then the entire DeFi "money-making story" is built on quicksand.

This idea led me to solutions like APRO and other Oracle solutions. At first, I thought it was just a technical module for inputting data into smart contracts, but after in-depth research, I realized—it's solving the most fundamental problem in crypto economics: how to bring real-world data onto the chain in a verifiable form, giving on-chain value a reliable foundation.

That's why tokens like $AT in Oracle networks exist—they essentially turn "verifiable truths" into economic incentives. Without trustworthy data sources, DeFi yields, no matter how high, are just illusions. Conversely, if the data is truly reliable, the DeFi ecosystem can be built on a foundation of real trust, rather than mutual gambling.

Every time I see that extra 180 yuan in my account, my first thought now is not excitement, but to ask myself: how solid is the data chain supporting this yield?
