David Marcus, former chief executive of Libra and chief executive of Facebook's tech division, is due to leave before the end of the year.

Golden Financial has announced that David Marcus, former chief executive of Libra and general manager of Facebook's technology division, will be leaving the company at the end of the year. Facebook is developing Diem digital rewards and the Novi wallet app, which Marcus oversees. Marcus' resignation will challenge Facebook's financial dividend technology. In 2014, Marcus switched from PayPal to Facebook and previously ran an instant messaging service. As a result of Project Diem, Facebook downgraded the project as the event unfolded, as financial regulators in some countries feared the services overseeing too much money, which could lead to breaches and affect private users. Facebook has already tested Novi in ​​Guatemala and the United States, allowing it to trade the stable Pax Dollar. However, some US lawmakers last month asked Facebook not to try, warning that it cannot trust Facebook when it comes to cryptocurrency.
