ChainCatcher reported that Vitalik Buterin tweeted that the modexp precompile is extremely unfriendly to ZK-EVM, with the worst-case scenario resulting in up to 50 times the average block computational overhead. He called for replacing it with equivalent EVM code via an EIP, even if it requires higher gas. He admitted that as the designer of modexp, he feels "ashamed and bows his head," and pointed out that its usage rate is extremely low and it increases the risk of consensus failure. He emphasized that the efficiency of the entire Ethereum ecosystem should not be sacrificed for the needs of a very small minority.
