I have heard a lot about reproducible builds as of lately, however I
fail to see how effective it would actually be against the issue they
are trying to solve, especially considering the extremely low risk of
the issue existing to begin with. There is a blog post that I believe
does a good job at summarizing the issue (if you can get passed all
of the smart-ass remarks).
My own criticism of it is that it creates the ironically named "chicken
or the egg" paradox. How so? Well, how do we know that our checksum
tool isn't backdoored either? In fact, that would be quite a more simple
solution. What's more, what about the compiler's compiler? And the
compiler of that compiler? Another solution (which wouldn't be as costly)
would be to reverse engineer the binary (yes, reverse engineering free
software). If all else fails, the only actual solution to the
*extremely* unlikely chance that these technologies have been
recursively backdoored would be to write a compiler in straight up
machine code (nope, not assembly, the assembler could be backdoored).
Who knows, maybe your editor is backdoored too, time to deal with the
I feel that lots of energy and time is being put into reproducible
builds, something that are vulnerable to the very issue they claim to
solve, when in reality there are much more important issues that can be
solved when it comes to security (like maybe using BitMessage instead of
e-mail, or at least adding a BitMessage chan since BitMessage is much
If I am missing something about reproducible builds that makes them
important then I would like to know. But from what I have heard and read
it's a rather insubstantial fad. Again, please correct me if I am wrong.
