Research on the Application of Blockchain Technology in Supply Chain Finance

At present, blockchain, with its distributed structure, trust mechanism, openness and transparency, and tamperability, has significantly optimized the information flow in supply chain finance, constructed a multi-body cooperation and coordination mechanism, and effectively solved the risk control problems. This paper analyzes the practice of Ant Gold's "Double Chain" platform, which demonstrates the role of blockchain technology in simplifying the financing link, aggregating multi-value chain, and promoting the innovation of supply chain finance. Finally, policy recommendations are put forward, including the development of supply chain finance, alleviating financing constraints and strengthening blockchain applications to promote the technology and the healthy development of supply chain finance. The study shows that the application of blockchain technology not only improves the efficiency and security of supply chain finance, but also brings innovative solutions for supply chain management
