This study examines the association between blockchain–IoT integration and supply chain transparency, with a particular focus on traceability efficiency and stakeholder trust. In increasingly complex global supply chains, traditional centralized information systems often suffer from data fragmentation, information asymmetry, and delayed verification. Drawing on a quantitative secondary data analysis of globally recognised initiatives, including IBM Food Trust, Walmart, Maersk, and reports from the World Economic Forum, the study investigates the relationship between the depth of blockchain integration and information latency in product traceability. A Blockchain Integration Index and Traceability Latency metric are analysed using Pearson’s correlation coefficient and Student’s t-test to assess statistical significance. The results indicate a strong negative statistical association between blockchain integration and traceability latency, suggesting that higher levels of blockchain–IoT integration are associated with substantially faster verification processes. The findings further suggest the presence of a maturity threshold beyond which transparency gains accelerate. While the statistical relationship is significant at the 95 per cent confidence level, the results should be interpreted with caution due to reliance on aggregated secondary data and a limited number of cases. Overall, the study contributes quantitative evidence to the literature on digital supply chains by highlighting how technological trust mechanisms are associated with enhanced transparency and operational efficiency.
