Smarter Operating Systems Will Use Wasm - The Coming OS Revolution
summary
k23 embeds a WASM JIT into a microkernel so the OS generates hardware‑tuned code, reduces memory use, and can snapshot, trace, and print stack traces; it’s written in Rust and uses a cranelift-based engine. the prototype implements virtual memory, interrupts, timers and async scheduling, runs a demo linking two WASM modules (a Fibonacci module demo), starts very quickly, and currently lacks host functions so full WASI/spec tests are not yet passing.
