My suggestion for published scientific papers would be to introduce a cryptographic hash to ensure forever integrity of the related data.

I'm not sure if this would relate to what you are developing here though, because it seems you are aiming more at the pre-publication phase where people are actively changing things?

But if a hash were included in the text of the original published paper then - for example once it was in a printed journal -then it could not be changed.

The paper would not need to contain a hash for every piece of data. There could just be a single hash of a text file that itself is a list of hashes for each related data file.

Then the data that was used to write the paper would be crystallised forever and could not be retrospectively manipulated.

And it is a very simple concept. Anyone could later download the data files and check the hashes for themselves.
