China has made 10 million people eligible to participate in its expanding digital yuan trial as it continues to lead global central banks in developing a virtual currency, according to a central bank official.

For now, people interested in using the digital yuan can apply to join “white lists” at state-owned banks that distribute digital yuan. There are now 10 million users of such white lists, Fan Yifei, deputy governor of the People’s Bank of China, said at a press briefing Thursday.
