That's not what I said. I've implied that it's hard to trust the output of some unknown compiler (eg, the "zig1.wasm" blob) and that it's easier to trust source code.

The Dozer article explains, under "The Descent Principle", how rustc will eventually be buildable using only source code [0] (other than a "512-byte binary seed" which implements a trivial hex interpreter). You still need to trust a computer to run everything on, though in theory it should be possible to gain trust by running it on multiple computers and checking that the result is the same (this is why any useful system bootstrapping project should also be reproducible [1]).
