Libra is a digital currency announced by Facebook in June, 2019. It will be issued, not mined, and it's value will be attached to a basket of fiat currencies. It's transactions will be recorded in a blockchain-like ledger - it will use something slightly similar to a blockchain but it will not be a blockchain like those crypto-currencies have.
"News outlets" listed some big names when Libra was announced in June 2019. Visa, Mastercard, Paypal and Spotify were said to be on-board. Most of their partners withdrew from the Libra association in October 2019.
The currency will be launched in 2020
