They have been for decades! Most scene releases that are packed will include an SFV file that contains the checksums of each of the package files so that you can check the file integrity.
Obviously those can be repacked and faked so you'd have to check multiple sources to ensure you get a genuine release, but yeah the scene groups are as usual way ahead of everyone else.
