Depending on who you ask, Libra—a cryptocurrency announced by Facebook last month—could usher in a new era of banking, or it could cause the next financial crisis.

Although Facebook shared plans for a Swiss non-profit called the Libra Association, which will manage its cryptocurrency’s reserves and network, the social media giant hasn’t provided many details about the governing body or Libra itself. Will Libra coins trade for $1 apiece? What happens when a Facebook account gets hacked? What if there’s a default on Libra’s underlying reserves? Many specifics are still to be determined—or studied.

…

Joseph Grundfest, a Stanford Law professor, said it would be a “delicious irony … if Facebook’s Libra proposal stimulates the United States government to develop a functionality that operates like Libra, backed by U.S. dollar deposits, but operated by the U.S. government.” Grundfest predicts a presidential candidate proposes a government crypto in “the not-too-distant future.” (Andrew Yang seems to fit the profile. He already has a crypto platform.)
