Research on Anti-tampering Simulation Algorithm of Block Chain-based Supply Chain Financial Big Data

In China, small and medium-sized enterprises are the foundation of overall economic development and are directly related to the employment and livelihood issues of the entire society. However, due to related issues, its financing costs are extremely high. For this reason, supply chain finance came into being. This article summarizes the shortcomings of traditional supply chain finance based on previous work experience. The author discusses the research on block chain-based supply chain financial big data tamper-proof simulation algorithm from four aspects: financial big data feature evaluation criteria, financial big data key feature extraction, supply chain financial big data key feature antitampering methods, simulation experiment and data processing content.
