Industry Use Cases on Blockchain Technology Applications in IoT and the Financial Sector

Modern supply chain applications are complex systems that play an important role in many different sectors. Supply chain management systems are implemented to handle increasing complexity and flows of goods. However, most of these systems are also increasing the complexity of providing trust and a global view of transactions in a distributed supply chain system. Blockchain technology introduces a new architectural style to support the traceability and trust of transactions performed by participants in a network. This chapter uses this emerging technology to realize a supply chain use case from JLP Meats in the UK with improved transparency, trust, and end-to-end querying while discussing potential challenges of realizing large-scale enterprise blockchain applications. The process of farm-to-fork is implemented and tested for traceability, item recall, block analysis, congestion enabling food safety, and sustainable agriculture. Potential challenges are highlighted in complex supply chains that need heterogeneous trade compliance and scalability.
