Global production and distribution speed bring a renewed focus on the safety, quality and validation of several important criteria in supply value chain. There are a growing number of issues related to safety and contamination risks that have established an immense need for effective traceability systems that act as an essential quality management tool ensuring adequate safety of manufacturing products. Traditional systems face challenges like centralized management, unclear information, and unsatisfactory data reliability. Basic IoT traceability systems offer some solutions but often rely on centralized models, making real-time tracking difficult. Thus, there is a call for a strong end-to-end track and trace system in manufacturing to improve product safety and reduce defects. The research proposes a Traceable Resource Unit (TRU) system using blockchain technology to enhance transparency and credibility. Blockchain can improve traceability by providing security and a clear transaction history, although its full advantages and development methods are still being explored.
