To compare it to. But for the tested fish verification maybe. Wait, how do we know they actually took representative samples of fish DNA? Well, obviously we are going to need hashes of video files of the tests. Also on the blockchain. But how do we trust that video corresponds to those tests? Timestamps and GPS stamps on the blockchain? There is no problem can't be solved without enough blockchain see. But I won't be syncing a node! In all seriousness, for now blind trust and reputation are still important and the rest is just layers designed to produce credibility. Not necessarily verification. And there is a difference. But I am in favor of more objective tools whenever possible so not to bag on blockchain efforts.
