On 18 June 2019, Facebook announced that it will launch its own cryptocurrency called "Libra".
Here are a few highlights of the Libra Project:
Libra is essentially a stablecoin, designed to be a law-volatility cryptocurrency backed by "a collection of low-volatility assets, including bank deposits and government securities in currencies from stable and reputable central banks"
The mission of Libra is to "enable a simple global currency and financial infrastructure that empowers billions of people".
Facebook has built a new programming language (known as "Move"), a blockchain ( "Libra Blockchain"), a regulated entity ("Calibra") and a custodial wallet (also known as "Calibra").
For now, the Libra Blockchain is being launched as a permissioned blockchain. The plan is to transition to a permissionless blockchain over time.
Libra is backed by a host of companies as diverse as Visa, Mastercard Paypal, eBay and Uber. For a full lists of founding members and partners of Libra, see https://www.bloomberg.com/news/articles/2019-06-18/facebook-s-cryptocurrency-project-who-s-in-and-who-s-out
