An Implementation of IoT-Based Product Tracking with Blockchain Integration for a B2B Platform

Digital Business-to-Business (B2B) platforms are increasingly playing an influential role in shaping business collaboration. Companies are relying more on such platforms to approach suppliers, customers, and service providers hence improving cross-sectoral collaboration and market reach. Digital platforms are including disruptive technologies such as the Internet of Things (IoT) as well as Blockchain to improve transparency and trust in business processes. However, notable challenges occur in integrating IoT information with product tracking information as well as storing them on Blockchain. This paper provides an implementation of integrating IoT-based product tracking with Blockchain in an open-source multi-sided B2B platform to address integration challenges. It focuses on product-tracking events and sensor data from the factory environment. A Blockchain service keeps cryptographic hash values for this information to avoid manipulation after the data storage.
