No i don't think it should, can i use as_usize_saturated!() here instead?

Is this good assumption? what to do if it is less or more?

Perhaps not, Can we through an error if they aren't equal. Something like
if input.len() != 192 {
return Err(Error::InvalidInputLength);

Do you need this file in runtime? Where should be placed

This is a mock trusted setup from that was used for testing with the EF audited bindings from c-kzg, afaik we do need it at runtime and should replace it with the official trusted set up once the ceremony is finished. I am not sure where it should live so i put it here. Do you think it should go in a different directory?

No i was using it at one point when writing the point verification by hand prior to using the EF bindings.

Closing in support for #668 |
Closes #526
Should be good for review!
