Yes, indeed. And you may very well want such an incentive system, because having many people distribute substitutes in a P2P system is a natural way for people to contribute their own bandwidth.

I think it's possible if the signature is detached from the reproducible work product to be signed. For example, it's like the difference between an embedded and detached signature of a file signed by GPG. Distributing a detached signature alongside a file doesn't change the hash of the file that's been signed.

Of course, you may not have built the build inputs yourself either - but those can be authenticated separately. (Recursion!)
