An experimental operating system for AMD64, built around the Strata kernel. Strata keeps ordinary process isolation and adds a tier where signed drivers and services run beside the kernel, so they can skip process-style IPC when the ownership rules allow it.
The project is on hold. Development has moved to Bedrock.
