Decentralized Data Storage

Definition ∞ Decentralized data storage involves distributing data across a network of peer-to-peer nodes rather than relying on a single central server or authority. This system enhances data resilience and censorship resistance by eliminating single points of failure. It represents a fundamental departure from traditional cloud storage models. Data integrity is often maintained through cryptographic proofs and distributed ledger technologies.
Context ∞ In the digital asset sphere, decentralized data storage protocols are gaining prominence as foundational infrastructure for Web3 applications and non-fungible tokens (NFTs). News reports often highlight new projects offering secure and verifiable data persistence solutions, crucial for ensuring the long-term accessibility of digital content and the functionality of decentralized applications. The ongoing discussion involves balancing storage efficiency with the robust security and autonomy that decentralization provides.
