Nothing about the blockchain can tell you whether somebody switched the labels, or who did it. And the not-guilty parties probably have no way of verifying what they received, either.

Having movements logged in a federated database has all the same properties.

What do you think is easier: making several companies run on their servers a federated databases or using a worldwide publicly available one?

What do you think is easier: convincing farms to send a cheap message to a federated database when they ship out products, or have them buy up insane quantities of computational power to compute crypto hashes, using insane amounts of power to do it?

Blockchain is crazy expensive to run. Why would anyone pay for that when there's dirt cheap alternatives that are every bit as effective at solving the problem?

who is paying for the federated database? i didn't know there are free ones.do you actually know the cost of an ethereum transaction? I'll help its 0.01$ and you don't have to do it all the time if you just run a side chain
