A popular belief in the DeFi community is that the faster the data updates, the better; the closer to real-time, the safer. Having observed on-chain data for a long time, I actually think this logic has issues.

Fresh data can indeed give traders and project teams peace of mind, making them feel they haven't missed any movements. The problem is, the market won't be gentle just because you have timely information. Especially in markets with low liquidity, frequently updated data can be drowned out by noise; when market volatility is intense, this obsession with speed can become a nightmare for the system.

Think about it—smart contracts lack subjective judgment; they simply execute based on the current data. But what if that data is just a temporary market fluctuation rather than a genuine signal? Overreacting can lead to irreversible consequences.

Compared to speed, stability is actually more critical. Stable data might seem a bit slower, even frustrating some people—after all, some firmly believe "movement is everything." But it is precisely this stability that allows the system to distinguish between true signals and fleeting fluctuations.

Therefore, the core issue with oracles isn't a lack of technological advancement, but a choice: the faster you want your data update frequency, the more uncertainty you must accept into the system. This is not just an engineering problem but a philosophy of risk management. In a highly automated DeFi ecosystem, stability is always more valuable than speed.
