Distributed Storage

Definition ∞ Distributed Storage refers to a system where data is spread across multiple independent computers or nodes within a network. Instead of relying on a single server, data is segmented and replicated, enhancing availability and fault tolerance. This architecture is a foundational element for many decentralized applications and services.
Context ∞ Distributed storage solutions are a frequent subject in news concerning data resilience and censorship resistance for digital assets and decentralized applications. Key discussions revolve around the economic incentives for node operators and the security protocols that safeguard data integrity across the network. Advancements in peer-to-peer storage protocols are continuously improving efficiency and decentralization.
