Failures of oracles often do not happen quietly—they are exposed during rapid market fluctuations. That’s why latency, update frequency, and underlying assumptions are much more critical than most people think. The reality is that no single oracle design can fit all scenarios. The true solution needs to be built on this foundation: providing a secure underlying framework while allowing different data sources and update mechanisms to be flexibly combined based on specific needs. Only then can developers and protocols have enough flexibility to meet the diverse application requirements in the DeFi ecosystem.
