The Ethereum-based TraceHarvest just started, with the service you can track the whole supply chain in the agriculture and food industry. The project was build with the cooperation of Bayer, the biggest agricultural firm in the world. They are testing the solution on soybean and corn, in the USA and South-America.
The agriculture and the food industry are strategic areas on a geopolitical scale, the countries try to improve and stabilizing them all around the world. More team working on it in the wider blockchain-industry, currently the VeChain is the biggest, but they are not a “food-only” project.
