Bivdi: An Operating System Without Ambient Authority
Bivdi proposes a capability-secure, object-centric operating system in which programs receive only the authority explicitly handed to them.
- For
- Systems programmers, security researchers, and AI-agent builders
- Worth noticing
- The model defines six core primitives and rejects root, sudo, and a global namespace.
Field notes
Bivdi organizes its proposed operating system around six primitives: identity, capability, object, event, desired state, and resource. Its security model treats authority as an unforgeable handle that can be narrowed through delegation but never expanded, while resource budgets cover hardware categories including GPUs and NPUs. The site exposes architectural decisions, proposals, open questions, documentation, and a roadmap; its Phase 0 runtime is identified as in progress.
