Decentralized Data Storage Solutions using Hyperledger Fabric

As geospatial data grows exponentially with the various advanced photographic capture technologies and satellite imagery being readily available and accessible, the need for secure and scalable storage systems grows larger. Blockchain-based distributed data storage and access systems can help provide an apt solution to this ever-looming issue. This paper talks about how Private Blockchain using IPFS (Interplanetary file System) and Linux Hyperledger technologies can be utilized for the Storage & Retrieval of Geospatial data. This paper explains the flow of the data from the point of generation to the point of retrieval from the Blockchain. The image is stored into IPFS Decentralized servers where we are provided with a CID (Content Identifier) for every unique entity. The CID is stored into the Hyperledger for the additional layer of blockchain-based security. For data retrieval, we simply enter the specific CID into the Hyperledger server through the authorized nodes with Keys to the private blockchain. This study aims to make the technology for the safe storage and reading of such data available.
