Fault Isolation

Definition ∞ Fault isolation is a system design principle that restricts the impact of a component failure to a localized area. In blockchain networks, this means a malfunction in one part of the system does not cause a cascading failure across the entire network. It enhances overall system resilience and stability. This approach minimizes the potential for widespread disruption.
Context ∞ Discussions about network robustness and security frequently address the implementation of fault isolation mechanisms within blockchain architectures. Sharding and modular blockchain designs are examples where fault isolation is a primary objective, aiming to contain issues within specific sub-chains or execution environments. News reports often praise systems that demonstrate strong fault isolation capabilities during stress tests or real-world incidents.
