BFT Security Trade-Off

Definition

BFT Security Trade-Off refers to the balance between safety and performance in distributed systems. Byzantine Fault Tolerance (BFT) consensus mechanisms prioritize network integrity even when a portion of participants behave maliciously. This resilience often comes at the expense of transaction throughput and latency, requiring more communication rounds among nodes. Consequently, systems employing strong BFT protocols frequently exhibit lower scalability compared to those with less stringent security models.
