I remembered we hashed datalength into the data too. why is it correct here
There was a problem hiding this comment.
It appears that the place where we hash data and length isn't referenced here and seems to be isolated away. In this code it appears that the data for the msp tree is from the other way the hash is created. This is the same way for 4844 from what I can tell. Interesting part is, even if we match the hash data to each other, there is still no connection between the 2 systems on the contract level. Maybe something offchain does.
