Distributed ledger technology is an immutable data storage and transparent system, which is a constituent component that empowers the FSCM (Food supply Chain Management). Due to the autonomous and immutable data feature, the scalability of blockchain technology is quite a challenge. A supply chain is a network that flows product from suppliers to the final consumer, which produces a high volume of data. In the blockchain, processing high volume of data is quite a significant issue and may affect business profit. To overcome the issue, Big Data and User Controllable Code for Smart Contracts (UCCSC) will be integrated with the blockchain-based FSCM system. Big data technology is typically used to analyze high volume of both structured and unstructured data, which is very difficult to process using habitual database and software techniques. The UCCSC integrates the blockchain and big data and manage the user in the FSCM system. This paper mainly discusses the integration of blockchain-based FSCM and Big Data, and the mechanism that supports such system.
