The source is a journalistic analysis, written by IT journalist Takafumi Makino, concerning the introduction and implications of the digital yuan in China. It explains that the digital currency, often referred to as DC/EP, is distinct from existing mobile payment systems like Alipay and WeChat Pay, which are merely digital wallets, while the digital yuan is the money itself. The document details a large-scale experiment in Shenzhen where citizens used the digital currency and outlines its technical foundation, including the use of UTXO (Unspent Transaction Output) technology, similar to Bitcoin, to manage transactions. Furthermore, the analysis emphasizes the Chinese government's key objectives for the digital yuan: to boost the competitiveness and technological capabilities of its traditional banks and, more significantly, to advance the internationalization of the yuan as a global reserve currency, particularly within Southeast Asia and along the Belt and Road Initiative.
