Vitalik Buterin just declared DeFi as Ethereum’s “killer app.” In his new post, he compares it to Google Search, the dependable core business that powers everything else.

Ryan and David break down why Vitalik believes DeFi has finally earned this title, how it survived the volatility of the last cycle, and what it means for ETH as collateral, culture, and revenue. They cover the Google analogy, the risks DeFi has outgrown, and why this moment could define Ethereum’s future.
