What you and many others fail to understand, (or more believably use as excuse to FUD) is the fact that not rolling back would exactly lead to the situation in where protocol would be exploited.
Therefore same situation.
Eth.
What you obviously don't understand:
Did VRC fix the protocol? No... VRC is still vulnerable to exactly the same majority holder attack.
This is why Proof of Share coins are inherently inferior.
VRC cannot fix the flaw, because it's built into the protocol. The coin is permanently flawed.
This is a wrong conclusion, in my opinion. The problem is not POS protocol. The problem is the scale. A SMALL POS is a problem. A big one is the solution.
