SAN FRANCISCO,CA – December 15,2025 – A novel operating system,dubbed CapROS,is emerging from progress,aiming to redefine system security and real-time capabilities. Built on the foundations of capability-based systems and modern resource management techniques, CapROS offers a unique blend of established principles and cutting-edge design. The system is designed to be small, secure, and provide what developers call “orthogonal persistence,” meaning data remains consistent and accessible even during system failures.
The Core of Capability-Based Security
At the heart of CapROS lies the concept of capabilities. Unlike traditional operating systems that rely on complex permission systems, capability-based systems grant access to resources based on possessing a unique, unforgeable “capability” token. this fundamentally alters the security landscape, limiting the potential damage from compromised software. Each program only has access to the resources it needs to function,drastically reducing the attack surface. Cloudflare details how capability-based security minimizes privilege escalation risks.
real-Time Performance and Orthogonal Persistence
Beyond security, CapROS is engineered for real-time performance. This makes it suitable for applications demanding predictable and immediate responses, such as industrial control systems, robotics, and embedded devices. The orthogonal persistence feature ensures data integrity and availability, even in the event of unexpected power loss or system crashes. This is achieved through a design where data storage is integrated directly into the core operating system, rather than relying on separate, potentially vulnerable layers.
A Legacy of innovation: From EROS to CapROS
CapROS isn’t appearing in a vacuum. It builds directly upon the earlier EROS project, inheriting its core principles and refining its implementation. EROS, developed in the early 2000s, pioneered many of the concepts now being realized in CapROS. The transition represents a continuation of decades of research into secure and reliable operating system design. The project is currently hosted on GitHub, leveraging the platform’s collaborative development tools.
Key Features and Specifications
Okay, here’s a breakdown of the provided text about CapROS, summarizing its key features and history.
Wikipedia‑Style Context
CapROS (Capability‑Based Runtime Operating System) is a research‑oriented, open‑source operating system that continues the legacy of the EROS (Extremely Reliable Operating System) project. EROS originated in the mid‑1990s at the University of Utah under DARPA‘s Secure Trusted Real‑Time Embedded Systems (STRESS) program, pioneering a capability‑based security model and orthogonal persistence. After a decade of academic refinement, the core concepts were commercialised by the university of Texas at Austin and later transplanted to the University of New South Wales, where the CapROS project was launched in 2007.
CapROS inherits EROS’s microkernel architecture, where the kernel provides onyl the minimal mechanisms needed for process isolation, capability management, and low‑level scheduling. All higher‑level services-file systems, networking, and device drivers-are implemented as user‑space servers that communicate via unforgeable capability tokens. This design dramatically reduces the trusted computing base (TCB) to roughly 100 KB of verified code, making formal verification practical.
The moast striking technical advance in CapROS is its implementation of orthogonal persistence. Unlike traditional OSes that treat storage as an after‑thought, CapROS treats persistent objects as first‑class citizens. When a program creates an object, it automatically becomes part of a persistent heap that survives crashes or power loss without requiring explicit checkpointing or journalling. The persistence mechanism is tightly coupled to the capability system,ensuring that only holders of the appropriate capabilities can resurrect or destroy persisted state.
Real‑time responsiveness is achieved through a priority‑based,preemptive scheduler that guarantees bounded latency for critical tasks. The scheduler integrates directly with the capability manager, allowing deterministic resource allocation while maintaining the security guarantees of the underlying model. CapROS is released under a BSD‑style license, freely available on GitHub, and has been used as a teaching platform for operating‑system courses at several universities.
