One thing I struggle with understanding for all these blockchain based solutions is the fact that the "trust" aspect fails in the face of an adversarial counterparty. For example, how do you know that the fish with id XYZ was _really_ ethically sourced? You only know that the counterparty asserts that fish XYZ was. The only advantage that I can see to the current system is that you can trace that assertion back to the originator.
