NixOS uses a cache that works like this; it's source-based like Gentoo but for packages in cache it will download the cache rather than rebuilding. (it will rebuild if you configure the package in such a way to invalidate the cache, or install a package not in cache) Besides the global cache for the whole distro, you can also set up caches for other software. For example, if you build your projects with Nix, you can have a cache for your projects (so that new contributors won't need to recompile everything from scratch). That's the premise behind https://www.cachix.org/ https://www.cachix.org/ The only difference is that Nix caches aren't fine grained like ccache and sccache
