Fault Tolerance

Definition ∞ Fault tolerance is the property of a system that allows it to continue operating correctly even when one or more of its components fail. It is a design principle aimed at preventing system failures by providing redundancy or alternative operational pathways. A fault-tolerant system can withstand a certain level of disruption without ceasing its intended function.
Context ∞ In blockchain and digital asset networks, fault tolerance is a critical characteristic ensuring the continuous availability and reliability of services. News reports may discuss a network’s fault tolerance in the context of its ability to withstand attacks, node failures, or other disruptions without compromising transaction finality or data integrity. Protocols that demonstrate robust fault tolerance are generally perceived as more secure and dependable.
