Federated Byzantine Fault Tolerance (FBFT)

FBFT is a variant of the BFT algorithm that has been implemented in payment-protocol-based blockchain platforms such as Ripple and Stellar. Both of these platforms perform critical transactions, such as cross-border payment, by dealing with fiat currencies. Due to their criticality, the consensus model should be fault resistant to avoid any attacks.

Ripple consensus protocol

An overview of the Ripple consensus protocol was covered in the previous chapter, along with its platform's architecture. Each node implements the FBFT consensus model by voting on the transactions. Each node in the network maintains a list called a Unique Node List (UNL), comprising trusted Ripple nodes. Each node broadcasts ...
