Why must the entire chain be included in calculations if it's already been validated. Why can't the validated portions be archived to save energy?
There is no difference between those two things. If you have a data set that includes only things that you have fully validated all of and you confirm that something is in that data set, you have fully validated all of it. So checking that it's in a data set of things you have validated cannot be done instead of validating the entire chain because it does validate the entire chain.
I'm not sure what you mean by &quot;archived to save energy&quot;. If they aren't archived, they're stored. If they are archived, they're stored. So I'm not sure how energy would be saved.
