      Not if you have a consensus algorithm and the machines all return a hash of the video they encoded. If they build IPFS support then the encoding machine could upload the file there, return the IPFS content address and the server can then pick an agreed upon address.

        I’m not OP, but if transcoding is happening on user CPUs, it’s theoretically possible to modify or inject stuff into the transcoded video. There’d need to be some way of validating a transcode matches the original, which is non-trivial.
        A consensus algorithm could work, but that would massively increase the required compute. I’m not even sure things like NVENC vs CPU ffmpeg are deterministic in how tbey compress video. Different encoders could very likely end up with visually identical transcodes, but the hashes wouldn’t always match.
        Maybe someone else has a better idea for validating transcodes?
