The World Economic Forum, which hosts the annual Davos meeting in Switzerland, recently published a survey about central bank experimentation with blockchain technology. Dozens of central banks around the world are investigating whether distributed ledger technology has a role to play in filling central banking functions.
The most interesting application that the WEF report mentions is central bank digital currency, or CBDC. Right now, the only type of money that central banks provide for us regular folks is cash. A CBDC would allow us all to get our hands on a digital version of central bank money.
