SAN FRANCISCO—Facebook Inc Chief Executive Mark Zuckerberg on Tuesday ordered one of the biggest management shakeups in the history of the social network, giving more responsibility to his chief product officer and launching a blockchain division.
The shakeup appeared to consolidate power at the sprawling internet company, although it included no firings or outside hires and did not change the role of either Zuckerberg or Chief Operating Officer Sheryl Sandberg.
