Fault Tolerance System

Definition

A Fault Tolerance System is a design approach within blockchain networks that allows the system to continue operating correctly even when some of its components fail or behave maliciously. This capability is achieved through redundancy, error detection, and recovery mechanisms, ensuring uninterrupted service and data integrity. It is crucial for maintaining the reliability and availability of decentralized ledgers, particularly in the presence of network outages or adversarial attacks. Such systems prevent single points of failure from compromising the entire network.
