Traceability Blockchain Prototype for Regulated Manufacturing Industries

Blockchain emerged as a peer-to-peer trust platform for trading virtual currencies and evolved to be used for different problems including supply chain provenance. Due to stringent requirements of safety, regulated manufacturing and service industries such as aerospace, healthcare, and transportation require regulated traceability for parts, from source to the last customer, with detailed information requirements for each handover and operation. In this research, we analyzed the current traceability problem and list use cases of a traceability blockchain platform. A prototype platform is developed for the aerospace industry where every single part is required to have source and path traces recorded by certified supply chain actors. We evaluate the efficiency benefits of the platform in terms of duration and address future research topics.
