What if we reduce the block size to 0.125MB? That will allow 0.375tx/s.
If 3->24 sounds "almost the same", 3->0.375 also sounds almost the same.
We will have 50000 full nodes, instead of 5000, since it is so
affordable to run a full node.
If 0.125MB sounds too extreme, what about 0.5/0.7/0.9MB? Are we going to
have more full nodes?
No, I'm not trolling. I really want someone to tell me why we
should/shouldn't reduce the block size. Are we going to have more or
less full nodes if we reduce the block size?
