The problem with traceability systems comes down to interfacing between the various nodes. Interoperability is probably the largest obstacle on the road to provide a full farm-to-table product tracking.

Probably not so much of a problem for the fully vertically integrated companies - especially those that also build or control their electronic systems, but large parts of agriculture still consists of independent actors on each node.

IIRC, the argument was that blockchain does not explicitly "solve" the problem, but rather that interoperability between blockchain-based systems will be easier than between those using completely different standards.

And of course, then you have the problem that food can travel around the globe many times before ending up on the table. Which again means more trust.
