According to the tech website Cheddar, Facebook is "very serious about it".
However, "people familiar with the matter said the social network doesn't have plans to hold a so-called initial coin offering (ICO) by offering a limited number of virtual tokens for the public to buy at a set price," the report said late Friday.
Facebook has over two billion users globally and launching cryptocurrency will allow them make payments using a virtual currency like Bitcoin.
"I'm setting up a small group to explore how to best leverage Blockchain across Facebook, starting from scratch," David Marcus, currently the executive in-charge of Facebook Messenger, said in a post.
In a statement later, Facebook said: "Like many other companies, Facebook is exploring ways to leverage the power of Blockchain technology. This new small team will be exploring many different applications. We don't have anything further to share".
Global spending on Blockchain solutions is expected to reach $2.1 billion in 2018, more than double of the $945 million spent in 2017, market research firm International Data Corporation (IDC) said earlier this year.
