That is a pretty exhaustive example. And the timestamp process looks pretty foolproof. Couple of questions though - How would the IOT device in the shipping load know what temperature the olive oil has been? Please don't say the IOT device can be placed in farms because we are currently talking about a logistics systems. And even if the IOT was placed in the farms - how would anyone verify if the IOT ie the source of data was hacked. Maybe just enough to show that the farm is producing 10% more extra virgin oil? How would the blockchain entries be managed? Because remember a block is added via majority rules - PoW or PoS. So, in case of olive oil manufacturing - who would verify if the IOT entry is correct? What happens if the IOT is not tampered and just malfunctions giving incorrect data?
