Privacy commissioners from the Americas, Europe, Africa and Australasia have put their names to a joint statement raising concerns about a lack of clarity from Facebook over how data protection safeguards will be baked into its planned cryptocurrency project, Libra.

Facebook officially unveiled its big bet to build a global digital currency using blockchain technology in June, steered by a Libra Association with Facebook as a founding member. Other founding members include payment and tech giants such as Mastercard, PayPal, Uber, Lyft, eBay, VC firms including Andreessen Horowitz, Thrive Capital and Union Square Ventures, and not-for-profits such as Kiva and Mercy Corps.
