Let me paint you a picture. Imagine you're a fund manager with a fiduciary duty to pension funds. Teachers' retirements. Nurses' savings. You look at DeFi yields and think, "That's interesting." Then you ask your risk team to evaluate it, and they come back with one question: "Where's the data coming from, and who's responsible if it's wrong?" Most oracles can't answer that in a way that satisfies legal and compliance teams. Most oracles weren't built to.
