Research on the volatility of financial assets based on the DCC-GARCH model in the context of the application of blockchain technology

This paper introduces and applies the GARCH model, the main financial asset market risk measurement method, and makes an empirical study of China's open-end fund market risk by using the semi-parameter method.Based on the estimated result, we introduce DCC-GARCH model to describe the dynamic correlation of the sample fund, analyze and judge the dynamic coefficient. It is concluded that before blockchain technology was widely used, the volatility of financial assets showed the characteristics of disorder, irregularity and convergence in the “big event” year.
