I've been thinking about DeFi lately. On the surface, everyone is competing over data speed, price accuracy, and high yields, but the deeper you go, the more you realize—these are not the core bottlenecks. What's truly critical? Can you clearly explain on the spot why you must do this particular step in this way?

After being in this space for a while, you realize that DeFi is now fully automated. Liquidations, settlements, asset reallocation—once certain conditions are triggered, actions are executed immediately, leaving no room for reaction. In the past, you could rely on the project team's reputation and historical data, just say "trust me," and some would follow. But now? That’s no longer effective. Many people have been burned, and trust can no longer be maintained with words alone; solid evidence is required. Every operation's logic must be laid out step by step, demonstrating that under the market conditions at that moment, this move was justified.

That's also why, when designing oracles, we didn't just pile on the "fastest data source" or "most price points." Instead, we designed each market update as a complete information statement: where the data comes from, how it's processed, when it was fetched, and why it triggers at this specific point. Every link must be traceable, auditable, and challengeable. Even if the market fluctuates or someone questions it, I hold not just empty words like "the code is fine," but a full trace from raw data to execution logic.

Of course, this approach isn't exactly "light"—certainty in data aggregation sacrifices some flexibility, timestamps require higher precision, and audit costs are higher. But in an era where DeFi is already automated and participants are already burned, I believe this is the fundamental skill needed to survive.
