Central Bank Digital Currency (CBDC) is a legal digital asset issued and managed by central banks of various countries. It is built on the technical characteristics of cryptocurrencies and operates on blockchain networks. Unlike the decentralized features of private cryptocurrencies, CBDC adopts a hybrid architecture directly controlled by the government, combining the stability of traditional currency with the convenience of digital assets. This new type of national currency operates in a regulated manner, designed to provide government-sanctioned payment solutions for the modern digital economy while maintaining effective control over financial circulation. CBDC represents an important transition of the traditional financial system into the digital era.
