According to tech news website Recode, Facebook has made long-time executive Chris Cox in-charge of Facebook, Instagram, WhatsApp and Messenger - now called a "family of apps".
"Facebook is also building a new team dedicated to Blockchain technology. David Marcus, the executive-in-charge of Facebook's standalone messaging app, Messenger, is leaving that post to run the Blockchain group," the report said late on Tuesday.
The Blockchain team would come under "New platforms and infra" run by Chief Technology Officer (CTO) Mike Schroepfer, who will also take care of Facebook's AR, VR and Artificial Intelligence initiatives.

Meanwhile, Chief Operating Officer Sheryl Sandberg will keep her duties.

"We may also be notified of such incidents or activity via the media or other third parties," Facebook said.
