Hi!
I've been working on a new version of the sha256 on-chain script that works using u4 as basic unit size.
In the process of doing it I created some interesting optimized lookup tables that are used by the algorithm, and some more that I could not use because of stack limitation, but still might be usefull for other parts.
This is the comparisson between the current sha256 algo and the new one.
