Black Wall desktop, live
A guided walkthrough of the hardened desktop session — compositor, terminal, sandboxed file manager, capability settings, and the verified app store.
Wayland compositor running on the capability microkernel.
System requirements
- x86_64 or ARM64 CPU with TPM 2.0
- 4 GB RAM (8 GB recommended)
- 12 GB disk for a persistent install
- UEFI with Secure Boot enabled
Capabilities
Capability microkernel
85% smaller trusted surface than a monolithic kernel; drivers run outside ring 0.
Zero unsafe drivers
Rust drivers with formal verification on memory boundaries.
TPM-attested boot
1.2 ms signed boot state validation before any user space starts.
Revocable permissions
Every app permission is a token you can revoke live, mid-session.
Reproducible packages
The store refuses anything that is not byte-for-byte reproducible.
Lockless IPC
0.18 µs message passing keeps overhead under 2% system-wide.
