It's not about what they know...
"Would you mind enlightening us further about what you know and they don't?"
... but what they choose to believe. The basic idea behind a blockchain is that you have a public log which everybody can check and everybody does check in a very distributed way.
That's only superficially what logistics need. Sure a common log would be good, but it shouldn't necessarily be public, also you only have a smallish number of partners. A more sensible solution would be to have a contract (as in shipping order) which is signed by both the sender and the recipient. This will be stored at all parties who need to know, and in case of disputes every side can proof which contract was agreed uppon. No "blockchain" or crypto puzzles nessesary.
