Center node: "orchestrating product provenance story when iota ecosystem meets the electronics supply chain space"
  Abstract: Trustworthy data is the fuel for ensuring the transparent traceability, precise decision-making, and cogent coordination in the supply chain (SC) space. However, the disparate data silos act as a trade barrier in orchestrating the provenance of product story starting from the transformation of raw materials into circuit board to the assembling of electronic components into end products available on the store shelf for customers. Therefore, to bridge the fragmented siloed information across global supply chain partners, the diffusion of blockchain (BC) as one of the advanced distributed ledger technology (DLT) takeover the on-premise legacy systems. Nevertheless, the challenging constraints of blockchain including scalability, accessing off-line data, fee-less microtransactions and many more lead to the third wave of blockchain called as IOTA. In this paper, we propose a framework for supporting provenance in the electronic supply chain (ECS) by using permissioned IOTA ledger. Realizing the crucial requirement of trustworthy data, we have used Masked Authenticated Messaging (MAM) channel provided by IOTA that allows the SC players to procure distributed information while keeping the confidential trade flows, data authenticity, and data accessibility rights. We devise a product ledger to keep track of product journey at each intermediary step. Furthermore, we also discuss the solution to integrate sensor data to track consignment location information along with transaction data during SC processes.
