DSB(Decentralized-storage-using-Blockchain) is a decentralized storage system in which each and every node is complete and indepentent.DSB has almost same architecture as Google File System(GFS). Only key difference between two is in DSB the master server(as in GFS) is replaced with blockchain. DBS can be used for decentralized storage system were the storage providers will get rewared with the amount of data stored on the basis of some cryptographic algorithms.It can be used in decentralized web.
