The United States dollar. The British pound. The euro. Most everyone is familiar with the names of some of the world’s best-known currencies.

Libra is the codename for a cryptocurrency that Facebook has been developing; the company reportedly will debut it next week and launch it in 2020. Unlike traditional, physical currencies, cryptocurrencies are all digital and used only for digital purchases and transactions. They also are not under the control of any nation’s central bank, such as the U.S. Federal Reserve. Dozens of cryptocurrencies currently are available for use, with Bitcoin being the best-known of those.
