Blockchain technology is a decentralised, distributed ledger system that offers a secure method for executing and recording transactions involving digital assets, eliminating the need for a central authority. Coordination of supply chains, especially in multinational enterprises, is complex and challenging. A large number of enterprises depend on technologies such as IoT and RFID for item tracking. Even with these improvements in technology, supply chains still face significant problems, including unforeseen interruptions and shortages of products. The implementation of blockchain technology is revolutionising supply chain management (SCM) by making it more visible, transparent and effective. This paper examines the use of blockchain technology in supply chain management (SCM), with a specific focus on its capacity to enhance transparency and encourage the adoption of environmentally sustainable practices. The research methodology for this thesis is based on secondary sources, including books and online materials. A descriptive approach is employed to provide a comprehensive overview of the subject, while the historical approach explores past trends. The abstraction and generalisation approach identifies key patterns and trends, and a thorough examination of the benefits and drawbacks is conducted to support the analysis. The thesis begins by identifying the main concepts of blockchain technology, covering key definitions, advantages, and limitations. The paper then presents the basic concepts of supply chain management and analyses two case studies to illustrate the practical applicability of blockchain technology in supply chain management. Blockchain technology has the potential to greatly enhance the way origins are tracked, so addressing significant issues related to transparency and traceability in supply chains. In essence, this paper argues for more research how blockchain technology can be used supply chain management (SCM) to fully exploit its potential and promote improvement in terms of transparency, efficiency, and sustainability.
