AI training can go off the rails with dirty data, and DeFi is even more likely to get liquidated if it relies on unreliable price feeds—both of these sectors are actually stuck at the data bottleneck. Have you ever wondered where on-chain price fluctuations and trading signals actually come from? That's exactly what the oracle middle layer is for. Now, some projects are starting to focus on cleaning and verifying data sources, essentially overseeing the entire process from collection and aggregation to on-chain submission. After all, garbage in, garbage out; whether it's AI models going off track or DeFi protocols having bugs, if you trace it back, it's most likely due to poor data quality. If this foundational infrastructure can truly be solidified, it would indeed provide significant support for the stability of the entire ecosystem.
