Hack The Valley

Hacking the food supply chain

A CSG/UZH,, and team participated in the blockchain/IoT hackathon at Thomson Reuters in Baar.

For the pitch, the team showed how the a step counter on the cow Elsa recorded its movement. This data was used for a happiness meter (the more the cow moved, the happier it was), and to distinguish if a cow is in the barn or outside. If the cow is more outside, the farmer gets more subsidies from the government. All data is aggregated and periodically stored in a smart contract. Thus, an end consumer can check if the cow was happy, as well as the government can automatically send Ether directly to the farmer.
