IBM has joined with a group of food supply companies and retailers to use the computing company’s blockchain tech to keep food fresh. Currently, it can take up to two weeks to track down the source of contaminated foodstuffs. But just like tracking cryptocurrency transactions all over the world, this consortium will harness IBM’s enterprise blockchain services to give its members access to a constantly-updating ledger of food, from source to store.

2:05 We believe that transparency is the
2:07 ultimate goal. Blockchain will give us the
2:09 ability to not only track where food
2:11 came from but how was it produced. Was it produced safely?
2:14 Was it produced responsibly? Is it
2:16 sustainably grown? How many dates of
2:18 shelf sites are left on that product? The
2:19 food system is a shared responsibility.
2:21 And for blockchain and traceability and
2:23 transparency
2:24 to work we need a lot of
2:25 people working together.
