consensusParams is redundant with the config that's already passed in

Remove since it's not used in this function if you apply my above comment

This was moved in the commit you referenced: https://github.com/bitcoin/bitcoin/pull/11824/commits/66aa1d58a158991a8014a91335b5bc9c00062f56

I noticed D2607 actually moves it but refers to a different commit. Can you comment on if this is a full backport of commit 66aa1d or just parts of it?

This is a full backport of commit 66aa1d5.
This part is not really "moved above" in the original commit, it was already there because used for segwit stuff that is not implemented in abc.
I kept this commit a pure refactoring, so the shared pointer is left where it stands from our original code, with the narrower possible scope.

You're right when you say that I move it in D2607. This is because there is a functional change in this commit which require a larger scope for a_recent_block.

I see now. That PR is super hard to read on Github. The rest of what you said cleared it up.

Cheers

It seems like there are some other backport missing here as there is compact block support missing.

1254 ↗(On Diff #7498)

This doesn't seem to match the patch from core.

It's probably worth doing a relayout on these comments, but this can be in another diff.
