Future of Finance: Secure 6G-Enabled Blockchain Networks with AI for Data Integrity

Abstract

The digital transformation of financial systems demands solutions that are secure, scalable, and capable of real-time processing. This paper presents an integrated framework that combines sixth-generation (6G) communication networks, blockchain technology, and artificial intelligence (AI) to address the growing challenges in financial data security and integrity. The proposed architecture leverages the low-latency and high-reliability features of 6G, the immutability of blockchain, and the adaptive capabilities of AI to support secure and automated financial operations. Key components include a layered network model, AI-driven anomaly detection, and privacy-preserving techniques such as federated learning and secure multi-party computation. The study outlines practical use cases including cross-border payments, central bank digital currencies (CBDCs), smart insurance, and decentralized identity verification. It also discusses limitations in scalability, regulatory compliance, and system interoperability. Future directions include quantum-resilient systems and the deployment of autonomous agents for real-time governance. The findings contribute to the design of secure and adaptive infrastructures for next-generation financial services.
