Regarding Ethereum’s upcoming crucial technical update announcement, Vitalik Buterin recently had to clarify some misunderstandings. It was stated in error in a tweet that the M3src binary statelayer of Ethereum was switching from src6 to 32 bits. This was clarified by Buterin, that it was really shifting from 64 bits to 32 bits. This is a significant change which may drastically speed up the proving on the network, leading to better performance. Buterin added “Now you can write reasonably-performant STARK proving code that runs on your GPU, in python!” He also shared the full arithmetization of poseidon in his X post.
