Design of a Credibility Evaluation System Based on a Unstructured Multi-Center Blockchain Security Architecture

Abstract

This paper designs a distributed multi-center identity authentication system based on blockchain technology. By supporting fine-grained declaration descriptions and privacy credentials related to zero-knowledge proof, the system achieves discretionary control of entities, privacy protection of user identities, and trusted data exchange. Since most blockchain-based identity authentication systems are based on public blockchain platforms, they are in essence traditional centralized identity management and verification methods. Therefore, this study establishes an open, transparent, trustworthy underlying identity architecture for users and upper-level applications, demonstrating the effectiveness and usability of the designed system through performance analyses and experiments.
