I.e. it is secure if you make several assumptions about economics of the
In my opinion the former is transfinitely more secure than the later.
But it's more of a philosophical question, sure.
The good thing about PoW-based consensus is that it is robust against
version inconsistencies and various accidents of this nature up to a
