# Decentralized Storage Nodes in Decentralized Storage receive rollup data sent by the Sequencer from Rollup Layer and store them. Storage Nodes run the ds-prover program of B² Network, periodically generating zero-knowledge proofs based on time and space for the stored rollup data. The ds-prover program sends the generated zk proof of storage to B² Nodes, and after verification, Storage Nodes receive certain storage rewards. The Storage Nodes in Decentralized Storage redundantly store copies of rollup data, ensuring the data availability of B² Network. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.bsquared.network/technical-design/da_layer/decentralized_storage.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
