The Short Version
The claim is true. China's People's Bank of China (PBOC) has developed and deployed a state-backed digital currency called the Digital Yuan (e-CNY). It has been in active public use since at least 2020, processing over 16.7 trillion CNY (~$2.37 trillion) in cumulative transactions by late 2025, with a major upgraded management framework taking effect January 1, 2026. While officially termed a "pilot" for much of its existence, its massive scale and public availability confirm it as a launched, state-backed digital currency.
