But IBM is targeting its new blockchain efforts not only at potential financial-industry customers,
but at a variety of logistics customers as well. IBM spokesperson Holli Haswell told Ars that a good example
for a non-monetary use of a distributed ledger could be shipping. If a business is trying to ship food across the county,
the companies in contract with one another could “apply contract resolution and auditing to the blockchain if for instance
a shipment of food is spoiled, allowing you to see the temperature of the cargo container throughout the shipping process.”
In such a scenario, shipments would be outfitted with RFID tags and sensors that could record temperature, location,
and any number of other statistics that could be reported back to the distributed ledger.
If they intend to do what they claim, how much data would be stored on this "distributed" ledger for each shipment?
It seems like in the first year alone with a decent amount of trucking using it, they would add about 32.85 Terabytes to this trucking blockchain.
How would they keep it distributed?
They can do this if they want, but something like that needs a massive data center.
