The Byzantine fault tolerance system, or Byzantine Fault Tolerance (BFT), is a system that can solve the problem of the Byzantine army. Building a fault tolerant Byzantine system is a necessity, but also extremely difficult in a distributed system.
Advantages and Concerns With the pBFT Model
The pBFT consensus model was designed for practical applications and its specific shortcomings are mentioned in the original academic paper along with some key optimizations to implement the algorithm into real-world systems. On the contrary, the pBFT model provides some significant advantages over other consensus models.
