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

Abstract

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 off-chain 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.
