Great to see this becoming an expectation, or at least a well known aspiration. The link to the sigstore website provides a good introduction about how to achieve this goal.[0]
There's no fundamental reason why getting a malicious binary onto someone's machine should be easier than getting malicious source code into a repo, but unfortunately catching malicious source code might be "the other 90% of the problem", and might ultimately require something like decentralised developer reputation vouching, which is far from being a solved problem.
