Design and Implementation of a High-Level Security Evaluation of Blockchain System

Abstract

In recent years, blockchain technology integration and application has gradually become an important driving force for new technological innovation and industrial transformation. While blockchain technology and applications are developing rapidly, the emerging security risks and obstacles have gradually become prominent. Attackers can still find security issues in blockchain systems and conduct attacks, causing increasing losses from network attacks every year. In response to the current demand for blockchain application securitydetection and assessment in all industries, and the insufficient coverage of existing detection technologies such as smart contract detectiontechnology, this paper proposes a blockchain core technology security assessment system model, and studies the relevant detection and assessment key technologies and systems. A security assessment scheme based on a smart contract and consensus mechanism detection scheme is designed. And the underlying blockchain architecture supports the traceability of detection results using super blockchains. Finally, the functionality and performance of the system were tested, and the test results show that the model and solutions proposed in this paper have good feasibility.
