  3. I guess https://github.com/seL4/l4v/tree/rt is the ongoing verification work for that

  5. …The safety is achieved by a large external theorem prover and a synced copy written in Haskell. https://github.com/seL4/l4v Typechecks are form of proof. It's easier to write provably safe Rust than provably safe C because the proofs and…

  6. …can be achieved is sel4, which while it is written in C has a separate proof of its correctness: https://github.com/seL4/l4v The proof is much, much more work than the microkernel itself. A proof for something as large as webP might take…

  9. …changes here: https://github.com/AmbiML/sparrow-kernel/commits/sparrow but I don't see a fork of https://github.com/seL4/l4v anywhere inside AmbiML. I mean, it does also claim to be "almost entirely written in Rust", which is true if you…

  16. Yeah, that's the basic idea of refinement based program verification. An example of that is: https://github.com/seL4/l4v There are many programs which can be nicely specified with logic, and which could thus be treated this way. That we…

  18. Here is seL4 proof: https://github.com/seL4/l4v To quote, "Most proofs in this repository are conducted in the interactive proof assistant Isabelle/HOL".
