LG CNS and the Bank of Korea have successfully tested an AI-powered digital currency payment system, marking a significant milestone in the central bank's Project Hangang. Conducted in Seoul, the test demonstrated a fully automated payment process managed by an AI agent, which autonomously handled product searches, purchase decisions, and payment execution without human intervention. This development represents a major step towards operational digital currency infrastructure in South Korea. The system utilizes deposit tokens on a digital currency platform, integrating smart contracts and oracle networks to enable the AI's decision-making capabilities. This innovation promises enhanced efficiency and reduced human error in financial transactions. As part of the global race in central bank digital currency (CBDC) development, South Korea's progress aligns with similar initiatives in China and Europe, positioning the country as a leader in next-generation monetary technology.
