Combined application of blockchain technology in fractional calculus model of supply chain financial system

Abstract This paper mainly studies the application of fractional calculus system in the financial system of blockchain supply chain. Firstly, based on the blockchain supply chain game model, the paper introduces the theory of fractional calculus, establishes a three-dimensional supply chain fractional calculus game model which is closer to the actual situation, and analyzes its dynamics by using the theory of nonlinear dynamics. Learning characteristics, controlling the behavior of chaos. Finally, the dissertation, distributed storage, traceability, tamper-proof and intelligent contract features of blockchain technology are applied to the bank credit system to verify the feasibility of this system.
