Demonstrating a Hyperledger Fabric-based Blockchain with Knowledge Graphs for a Supply Chain Ecosystem

Supply chain management is one of the leading applications of chain-based distributed ledger technology, such as blockchain, due to its features of traceability, automation through smart contracts, tamper-resistance and immutability.One of the most common types of blockchain implementation for a supply chain ecosystem is Hyperledger Fabric, which follows a modular architecture.Within the supply chain, innovators have been emphasising scenario generation for trade optimisation via predictive algorithms using content from the blockchain.However, to support such utilities, a pipeline with data accessibility is required, which is the motivation behind this work.Chaincode, InterPlanetary File System (IPFS) and offchain execution enable the pipeline to provide knowledge graphs that can further facilitate insights into the type of blockchain data with better control and privacy-aware filtration.
