Evaluating the Use of Blockchain Technology in Enhancing Transparency and Security in Supply Chain Management

Abstract

Blockchain technology is revolutionising UK supply chain management by improving security and transparency. This study examines how blockchain mitigates fraud, improves traceability, and optimises operational efficiency through Everledger, IBM Food Trust, Maersk TradeLens, and Walmart UK case studies. Results show that immutable blockchain ledgers and smart contracts improve supply chain integrity but are hindered by factors such as high implementation costs, shortage of technical expertise, and specific regulations such as GDPR compliance in the EU. Comparative analyses with the US, China, and the EU show the UK's regulatory leadership but underperformance in investment. The report suggests UK government incentives, blockchain standardisation across the industry, and workforce development to support wider adoption and help realise its potential in securing UK supply chains.
