Supply Chain Finance Access Control Evaluation System Based on XGboost

Abstract

In this paper, we propose a decentralized access control scheme for supply chain finance, which takes credit score as an important basis for access policy, establishes a credit score model by using XGBoost algorithm, and mines credit risk characteristics based on user's historical data, so as to improve the assessment accuracy and decision-making reliability. Experiments show that smart contracts can automate the execution of access policies, optimize process efficiency while ensuring transparency and security, and provide stable system performance with good scalability. At the execution level, smart contracts are used to automate the assessment of user credit, ensure the real-time and tamper-proof judgement of privileges, and improve the transparency and security of the system. The experimental results show that the constructed system has good performance stability and scalability in a multi-node environment.
