Background With the rapid development of internet technology and the advent of the big data age, the scale and complexity of financial data has grown exponentially. Modern financial systems face multiple challenges of mass data processing, real-time transaction verification, privacy protection, and compliance auditing. Although the traditional centralized financial system has advantages in processing efficiency, the traditional centralized financial system has inherent defects of single-point faults, easy data tampering, difficult audit tracing and the like.
