I know this is a delayed reply.
Without intending to revive an older thread, my intentions are to clarify
what I have meant in my original post just in case anyone misinterprets
where I said
"For example would be something like this:
If block = (empty OR <%75 of mempool) THEN discard
This threshold just an example."
I should have clarified that with this idea blocks would not be rejected if
does not match what that nodes have in their mempool, because as you have said,
there is no consensus on the contents of mempool and the mempool will vary from
node to node.
Instead what I have meant is that with this idea, nodes would only reject blocks if
they are empty or less than a determined percentage when compared to what is in mempool.
While this specific defense proposal I posted may or may not be a good idea, was only
throwing this idea out there to create discussion on possible defenses against an empty
or near empty block attack.
