"In the Walmart test, food shipments were tracked and digitally recorded via a blockchain. (Yiannas’s team’s manual search was the “control.”) From the start of their journey at the farm, pallets of mangoes were tagged with numeric identifiers. Every time they crossed another checkpoint—from farm to broker to distributor to store—their status was signed and logged."
How is this different from some kind of RFID tracking system? Still trying to understand the value add of blockchain in this example.
