  • But I am thinking that their workflows are reproducible builds, correct?

    A reproducible build is more than an automated build. It is a build process which enables any third party to build a binary that is bit-by-bit identical (see https://reproducible-builds.org/docs/definition/).

    So if I would build a specific release/commit of your application on my PC (given an identical development environment, i.e. same version dependencies, compiler, etc.) it MUST result in a bit-by-bit identical binary to the one you built on your development machine and the one the github workflows built.

    All these binaries would result in the same hash (and thus be verifiable by the same signature files).

    “Here is my very simple commit that you can read, and here is the executable in case you want to download the fixed wallet but are not technically savvy enough to build it”

    Other than a signed binary from a trusted developer/organization, there is (IMHO) no way for a non-tech savvy user to gauge the trustworthiness of a binary they download from the internet, and even then a signing key might have been lost or broken (see the recent Microsoft debacle w.r.t. AD signing key misuse).
