Block chain has developed as a technology that has promise for an industrial traceability system. It can be used in numerous situations. This study especially assesses the possibilities for block chain authentication and security while examining how block chain technology is employed in the supply chain industry. Block chain has developed as a technology that has promise for an industrial traceability system. The paper begins by reviewing the frameworks and systems currently in use for supply chain authenticity management. The block chain's underlying technology is then examined. With reference to a number of current uses, the interplay of block chain with supply chains is described in detail. It may also be used for a number of Supply Chain Management (SCM) system activities, including forecasting, quality assurance, inventory management, and logistics. One of the main goals of the SCM is to increase the traceability, transparency, and audit ability of the products as they move from suppliers, production locations, warehouses/distribution centers, to customers. The report concludes by outlining how block chain could be utilized to handle authentication, ensuring higher standards of security and trust within the sector, and do it in a secure and transparent manner. In conclusion, block chain technology has a lot of potential for enhancing the supply chain industry's current authenticity management procedures. Benefits would include increased data privacy, better security and trust, and lower costs. Furthermore, the widespread adoption of block chain would provide greaterStakeholder transparency, allowing users to track and trace items with confidence.
