# Zircon | |
Zircon is the core platform that powers the Fuchsia OS. Zircon is composed of a | |
[microkernel](/zircon/kernel) as well as a small set of userspace services, | |
drivers, and libraries in [/zircon/system](/zircon/system) necessary for the | |
system to boot, talk to hardware, load userspace processes and run them, | |
etc. Fuchsia builds a much larger OS on top of this foundation. | |
