Proof of Retrievability

Definition ∞ Proof of Retrievability is a cryptographic mechanism that allows a client to verify that a storage provider correctly stores a file and can retrieve it upon request. This ensures data integrity and continuous availability. It provides a trustless method for verifying data storage.
Context ∞ Proof of Retrievability protocols are vital for decentralized storage networks. They enable users to audit storage providers and confirm the persistent availability of their data without needing to download the entire file, thereby enhancing trust and verifiability. This technology underpins the reliability of decentralized cloud solutions.

A striking blue, spiky, crystalline structure dominates the frame, vertically bisected into two distinct halves. This visual metaphor illustrates a modular blockchain architecture, where sharding divides the decentralized network into smaller, manageable segments. Each half represents a shard chain, processing transaction throughput independently to enhance scalability solutions. The intricate, sharp forms symbolize the complex consensus mechanism and data integrity required for validator nodes to maintain the distributed ledger. This design optimizes network efficiency and data availability within a Layer 2 solution framework.
