I. Introduction
Sustainable Supply Chain Finance (SCF) is a critical aspect of global trade, enabling companies to obtain financing and optimize working capital while also enhancing supply chain efficiency. However, as businesses and consumers become increasingly concerned about sustainability and social responsibility, there is growing recognition of the need for more transparent and ethical supply chains. Recently, blockchain technology has come up as a possible solution to these problems, since it can make things more clear and easier to track. Distributed ledger technology, like blockchain, permanently records all business activity and transactions along a supply chain. More ethical sourcing practices, less waste, and improved environmental and social risk management are all possible thanks to the improvements in supply chain transparency and traceability made possible by this technology. Small and medium-sized businesses (SMEs) may find it easier to gain access to funding and compete with larger corporations using blockchain-based SCF. [1]
