The past few years have seen a spate of cyber attacks targeting multinational companies, governments, institutions and even individuals' data. Most of these attacks target the vulnerabilities of the centralized system of data storage, emphasizing that a novel approach to data storage must be developed to tackle long-standing issues with centralized systems. Blockchain technology - a decentralized ledger based system provides a viable alternative to many of these issues. The objective of this paper was to develop and test a decentralized document storage system using a private Blockchain network, Ethereum coins and the InterPlanetary File System(IPFS). Interim results suggested that the proposed solution can be implemented at scale for certain use cases including confidential documents of both private and public entities.
