Currently, Filecoin nodes support direct retrieval from the storage miners who originally stored the data. Clients can send retrieval requests directly to a storage provider and pay a small amount of FIL to retrieve their data.
To request data retrieval, clients need to provide the following information to the storage provider:
Storage Provider ID: The ID of the storage provider where the data is stored.
Payload CID: Also known as Data CID.
Address: The address initially used to create the storage deal.
Since most Filecoin nodes are also IPFS nodes, standard practice has been for Filecoin storage providers to also make available a hot copy of any given stored file through IPFS. Since the algorithm that generates a content address (CID) is the same for both Filecoin and IPFS, the client can request the CID of a file they stored on Filecoin and retrieve it from IPFS, if there is an IPFS node that is able and willing to serve the file.
