Zircon is the core that powers Fuchsia. It is composed of a kernel and a small set of userspace services, drivers, and libraries necessary for core system functions such as booting.

Although Zircon applies many of the concepts popularized by microkernels, it does not strive to be minimal. Instead, the microkernel-like architecture of Zircon enables Fuchsia to reduce the amount of trusted code running in the system to a few core functions:

• Memory management
• Scheduling
• Inter-process communication
