I just don't see that. Banks don't need small blocks to remain necessary.
FYI, small block force a side chain solution which is centralized and there in lies the problem.
I just don't understand why dynamic blocks are just not discussed, it smells of agenda.
... there is no discussion with dynamic blocks because think about for longer than 2 seconds, it goes like this:
"Hmmm, dynamic blocks what's that about?"
"Well the blocks can take any size up to a limit ...."
"Oh a dynamic block size
with a limit, what size should we make that?" ... and there it ends, it's the same discussion.
