Facebook Inc. revealed plans on Tuesday to launch a cryptocurrency called Libra, the latest development in its effort to expand beyond social networking and move into e-commerce and global payments.

Facebook has linked with 28 partners in a Geneva-based entity called the Libra Association, which will govern its new digital coin set to launch in the first half of 2020, according to marketing materials and interviews with executives.

Facebook has also created a subsidiary called Calibra, which will offer digital wallets to save, send and spend Libras. Calibra will be connected to Facebook's messaging platforms Messenger and WhatsApp, which already boast more than a billion users.
