Starbucks, the biggest coffee shop chain in the world, now allows its customers to trace the origins of its coffee using Microsoft's blockchain solution. Customers will be able to scan codes on the bags of coffee they purchase to discover their origins. Little information has been provided concerning the traceability solution other than the fact that it employs blockchain. Microsoft is one of the leading providers of blockchain-as-a-service platforms, though IBM's Food Trust platform is better known in the space.

As consumers become more concerned about the ethical sourcing of the products they purchase, the blockchain-tracing trend could rapidly begin to take hold.

This is a developing story and will be updated.
