What is the Definition of Fault Tolerant Systems?

Fault tolerant systems are designed to continue operating correctly even when one or more of their components fail. They achieve this resilience through redundancy, error detection, and recovery mechanisms, ensuring uninterrupted service and data integrity. These systems are critical in environments where downtime or data loss is unacceptable. Blockchain networks inherently possess fault tolerance due to their decentralized and distributed nature.

What is the Context of Fault Tolerant Systems?

Discussions in crypto news often highlight the fault tolerance of blockchain networks, particularly in relation to their resistance to censorship and attacks. Reports on network upgrades or new consensus mechanisms frequently emphasize improvements in fault tolerance. The ability of a blockchain to withstand various failures without compromising operations is a key measure of its robustness and security.
