Ok i got the first part of your answer but for the second part i'm not so sure. You mean that bigger blocks will likely cause more orphans?
Anyway thanks for clearing it out.
I think the point is:
- The more transactions a block contains, the bigger it is.
- Bigger blocks take longer to propagate on the network and get accepted.
- If 2 smaller blocks get confirmed before the bigger one gets a child, all TX included in the bigger block don't get confirmed, and this is the "orphan cost".
There is no motivation today for miners to include more TX, as it makes it very risky.
They play small and secure.
The question now, is : "how do we make sure bigger blocks get bigger rewards overall".
Or maybe I didn't get it right, which is also a likely hypothesis.
