AI Digital Currency Payments: LG CNS and Bank of Korea Unveil Groundbreaking Agentic Transaction System

SEOUL, South Korea – In a significant leap for financial technology, LG CNS and the Bank of Korea have successfully demonstrated an automated payment system for digital currencies powered by advanced agentic artificial intelligence. This pivotal test, reported by Yonhap News on November 15, 2024, represents a crucial phase in South Korea’s central bank digital currency (CBDC) development under Project Hangang. The demonstration specifically tested a payment infrastructure using deposit tokens, where an AI agent autonomously handled the entire transaction cycle from product search to final payment.

AI Digital Currency Payments: The Technical Breakthrough

The demonstration conducted by LG CNS and the Bank of Korea showcases a sophisticated integration of several emerging technologies. The system utilizes what researchers term “agentic AI” – artificial intelligence capable of autonomous decision-making within defined parameters. This AI agent performs three critical functions in the payment process. First, it conducts intelligent product searches based on user preferences. Second, it makes purchase decisions by evaluating options against predetermined criteria. Finally, it executes payments using digital currency infrastructure.

This technological approach differs substantially from conventional digital payment systems. Traditional systems typically require manual intervention at multiple stages. In contrast, the demonstrated system enables full automation while maintaining security protocols. The test specifically employed deposit tokens, which are digital representations of commercial bank deposits on distributed ledger technology. These tokens offer several advantages for payment systems, including programmability and seamless integration with smart contracts.

The technical architecture reportedly incorporates multiple layers of verification and compliance checks. Each autonomous decision by the AI agent undergoes validation against regulatory requirements and security protocols. Furthermore, the system maintains comprehensive audit trails for all transactions. This design addresses common concerns about AI-driven financial systems, particularly regarding accountability and transparency in automated decision-making processes.
