Bitcoin can definitely change how logistics are handled. But why would you want to make it decentralised? I wouldn't like shipping information or anything that I order on a public chain to be honest.Arent all the supply chain companies centralised already? What benefits would implementing blockchain bring? The supply chain will remain centralised anyway.

True, that is also the concern about if my shipping information is to be public, then my privacy might lost, like going which location = disclosing my home address / some people might know when does the government / army department delivering any dangerous good from and at what time, which might cause crime there too.
As I have made some research these days, I know that public chain may only applicable on some, as agreed from the above comment, the access of data might not be fully being public, it can be hybrid, required special permission. Then under this, what is the different between a decentralised blockchain and a centralised database? Does replacing by blockchain really help improving the logistics?
