Vitalik: The inefficiency of the modexp precompiled contract is dragging down Ethereum, but optimization should not be prioritized

Jinse Finance reported that Vitalik Buterin posted on X, stating, "As the original inventor of the modexp precompiled contract, I feel deeply ashamed. But modexp has indeed held back Ethereum to a large extent. On one hand, it is inefficient; on the other hand, its complexity exposes our ecosystem to a significant risk of consensus failures. We could certainly invest a great deal of effort to optimize this function—which is used by only 0.01% of people—whether at the original execution layer or the verification layer, but in my view, this is unwise—especially when there are more urgent scaling needs to address, and other parts of the protocol also urgently need strengthening."
