Single Point Failure

Definition ∞ A single point failure is a component of a system that, if it fails, causes the entire system to stop operating. In the context of decentralized systems and digital assets, this refers to any centralized element or dependency within a blockchain network or related infrastructure that could compromise its integrity or availability if it experiences an outage or attack. Decentralized technologies aim to eliminate single points of failure through distributed consensus, redundant nodes, and peer-to-peer architectures. Identifying and mitigating such vulnerabilities is crucial for maintaining the resilience and censorship resistance of crypto systems.
Context ∞ News often highlights single points of failure when discussing the security and decentralization claims of various blockchain projects or related services. Reports might cover outages of centralized exchanges or vulnerabilities in smart contracts that rely on external, non-decentralized data sources. The ongoing effort to remove single points of failure is a key aspect of advancing blockchain technology and ensuring the robustness of digital asset ecosystems.
