Practical Byzantine fault tolerance (pBFT) : (n - 1) / 3
I read those 2 things in a PDF that a friend of mine sent me.
The question is: are those numbers (2/3) or “(n-1)/3” constant? Or those numbers are established by the developers.
What makes those numbers? What’s the reason for 2/3 and not 2.5/3 ? Or why not (n - 2 ) / 3

Where are you getting those nonsense numbers from? Those don't reflect anything about how the network operates at all. – Anonymous – 2019-02-15T22:55:00.987
They are not nonsense. They are written on the Practical Byzantine fault PDF. It does reflect how the network operates (Not for Bitcoin’s blockchain though) – Juan – 2019-02-15T23:20:28.053
