Although blockchain was proposed in 2008 to solve the centralization problem in information exchange and eliminate the need for trusted third parties such as intermediaries or banks to conduct financial transactions, private blockchain applications today still suffer from the centralization problem. This situation has arisen because we cannot manage metadata on private or public blockchains, but a representation of this data as hashes or key values when the metadata is registered on central servers or the cloud. In this study, we highlight two decentralized storage platforms (IPFS and Sia) that can solve the centralization problem of current blockchain applications. We believe this work will be helpful for anyone working in Big Data and information systems related-fields.
