The electronic Chinese yuan is now being tested in cities such as Shenzhen, Shanghai and Beijing. No other major power is as far along with a homegrown digital currency. One Chinese citizen recently won a government lottery to try China’s latest economics experiment, Chinese digital currency.

China has charged ahead with a bold effort to remake the way that government-backed money works, rolling out its own digital currency with different qualities than cash or digital deposits. The country’s central bank, which began testing eCNY last year in four cities, recently expanded those trials to bigger cities such as Beijing and Shanghai, according to government presentations.

Over the last 12 months, more than 60 countries have experimented with national digital currencies, up from just over 40 a year earlier, according to the Bank for International Settlements. The countries include Sweden, which is conducting real-world trials of a digital krona, and the Bahamas, which has made a digital currency, the Sand Dollar, available to all citizens.
