Pathways OS
A completely novel real-time operating system and Type 1 Hypervisor built from scratch in 100% provable Rust.
Overview
Pathways OS is an upcoming operating system built entirely from the ground up. It is not based on Linux, BSD, Unix, Windows, macOS, or any other existing operating system. Every line of code is original, written in Rust, and formally verified using our compile-time HOL proof system.
Pathways OS combines a real-time operating system kernel with a Type 1 Hypervisor and a complete desktop environment into a single, cohesive system. All code is 100% provable Rust — verified correct at compile time through thousands of mathematical proofs derived from foundational axioms.
Not a fork, not a derivative. Pathways OS is a completely novel operating system. It shares no code, no kernel design, and no architectural lineage with any existing OS. Every component — from the bootloader to the window manager — is designed and built from first principles.
Core Components
Real-Time Kernel
A deterministic, formally verified RTOS kernel with guaranteed response times and provable scheduling correctness.
Type 1 Hypervisor
Bare-metal hypervisor for running guest operating systems (Linux, Windows, macOS VMs) alongside native Pathways applications.
Desktop Environment
A complete desktop environment with compositor, window manager, and GUI toolkit built natively for Pathways.
100% Provable Rust
Every line of code is formally verified at compile time using the GDS compile-time HOL proof system.
Formal Verification
Pathways OS is built using our compile-time HOL proof system, which provides mathematical guarantees of correctness. The proof library contains thousands of verified proofs derived from 10 foundational mathematical concepts and a small set of foundational axioms, all verified by the HOL kernel.
This means entire categories of bugs — memory safety violations, concurrency errors, scheduling failures, privilege escalation vulnerabilities — are eliminated at compile time rather than discovered through testing. The result is an operating system whose correctness can be mathematically demonstrated, not merely asserted.
Design Principles
- Provable Correctness: Every component is formally verified. If it compiles, it is correct.
- Real-Time Guarantees: Deterministic scheduling with mathematically proven response time bounds.
- Security by Construction: Capability-based access control with formal proofs of isolation properties.
- Clean-Sheet Design: No legacy constraints. Every design decision is made from first principles.
- Hypervisor Integration: Run existing OS workloads in VMs alongside native Pathways applications.
Current Status
Pathways OS is in active development. More details will be announced as the project reaches public milestones.
