AI Technical Summary

Technical Problem

Existing technologies in cross-chain regulation suffer from insufficient privacy protection due to static gradient aggregation, inability to adapt to compliance requirements of multiple countries in real time, lack of dynamic risk response mechanisms for fixed signer numbers, low research density on quantum dynamic thresholds and differential noise injection, and inability to effectively address quantum attacks and data leaks.

Method used

A dynamic threshold cross-chain monitoring system based on quantum random walks is adopted, including a quantum key generation module, a dynamic threshold control module, a quantum attack resistance module, and a differential noise injection module. The encryption key is generated through the quantum random walk algorithm, and the threshold value is dynamically adjusted in combination with data type, regional regulations, and real-time threat index. Laplace noise is dynamically added before federated learning gradient aggregation, and the system status is monitored in real time and fault response is triggered.

Benefits of technology

It achieves efficient and secure cross-chain supervision, enhances the security and compliance of the system, effectively responds to quantum attacks and data breaches, ensures privacy protection and compliance of data transmission, and is suitable for highly sensitive data scenarios such as cross-border finance and healthcare.
