Maybe I'm overly pessimistic, but isn't it quite likely that it will primarily be used as leverage against suppliers? If the suppliers themselves enter every piece of information into what is essentially a living contract, any error or omission could be considered a breach of contract and can be leveraged. If it was only about food safety and increased sales because of increased trust the solution you propose, maybe with some kind of basic digital signatures, would be fine, and probably much cheaper. From what I've heard, Walmart seems to like moneh very much, hence doing something a more expensive way is likely to be intended to increase their bottom line in more ways than one.
