“If the number of nodes that agree exceeds 2/3, the blocks or transactions of clients will be accepted”
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
