Facebook has discussed the matter with payments firms including Visa (V) - Get Report , MasterCard (MA) - Get Report and First Data Corp.

The initiative, seeking total investments of about $1 billion, has been underway for more than a year and is code-named Project Libra, according to the report. Bloomberg and the New York Times have previously reported that Facebook was looking to develop its own cryptocurrency that users of its WhatsApp platform could use to exchange money with each other.
A spokeswoman for Facebook's blockchain efforts declined to comment to the Journal, saying simply that it "is exploring many different applications."

In just the past 12 months, investments in cryptocurrency-related assets have nearly tripled to $14.4 billion, across more than 700 companies and funds, according to industry tracker Crypto Fund Research.

On Friday, the price of bitcoin jumped 5.7% to $5,690, according to the website CoinDesk.
