As globalisation grows, supply chains have become complex networks, creating management challenges for companies. To stay competitive, they face demands for improved transparency, traceability, and efficiency. Blockchain’s secure ledger presents a practical solution to increase visibility and tracking within supply chains.
This study used a mixed-methods approach, combining a literature review and a case study. This design enabled triangulation, strengthening result validity. The literature review provided a theoretical foundation for blockchain applications in supply chains, focusing on transparency, traceability, and efficiency. Academic and industry sources were selected for relevance and recency. A case study of Carrefour, a major European retailer, was used to analyse real-world implementation. Data was collected from company reports and press releases and analysed thematically.
The findings revealed that blockchain improves visibility and traceability, reduces inefficiencies, and enhances consumer trust. However, implementation costs, scalability, and security risks remain significant barriers to widespread adoption.
It is recommended that companies implement blockchain gradually, addressing challenges such as costs, training needs, and energy use. It can enhance transparency, boost consumer trust, and offer legal reliability when applied effectively. Future research may explore its integration with technologies like IoT and assess its environmental impact to support more sustainable supply chains.
