Vitalik Buterin wrote on the X platform, "As the original inventor of the modexp precompiled contract, I am deeply ashamed. But modexp does drag down Ethereum to a large extent. On the one hand, it is inefficient, and on the other hand, its complexity puts our ecosystem at risk of a large number of consensus failures.
We can certainly invest a lot of effort in optimizing (both at the raw execution level and at the verification level) a feature that only 0.01% of people use, but in my opinion, it is not wise to do so - especially when there are more pressing scaling needs to be addressed, and other parts of the protocol also need to be strengthened. "
