Facebook is "very serious" about launching its own cryptocurrency, news outlet Cheddar reported Friday. It's not the first time the idea of a Facebook coin has been floated, but it seems more apparent now in wake of Facebook's reshuffled executive structure and newly formed blockchain group. From the report: Facebook started studying blockchain almost a year ago, when a member of its corporate development team, Morgan Beller, began looking at how the social platform could use the emerging technology. At the time, Beller was the only Facebook employee devoted to studying blockchain, the digital and decentralized ledger that underpins cryptocurrencies like Bitcoin and Ethereum. Her work was thrust into the spotlight this week when Facebook announced that the vice president in charge of the Messenger app, David Marcus, would lead a new team to "explore how to best leverage blockchain across Facebook, starting from scratch."
