Context:
Reproducible builds ensure software can be rebuilt in an identical, bit-for-bit manner anywhere at any time using the same tools. This means that someone rebuilding the software from the same source code will get exactly the same results.
Why is this important? Because it’s a crucial aspect for supply-chain security.

Nix doesn’t really guarantee reproduciblity, though. It’s a neat idea for deterministic configurations. But bit by bit reproducible binary builds are an entire difference beast. GNU Guix has way more promise in that regard
