COVID-19 test kits. Vaccines. Medical Cannabis and CBD products. Food products. These are just some of the assets that require a certain temperature, or proof of quality, or proof of authenticity as they are stored and transported from the original manufacturer to the point of usage. Media Sourcery's Cold XChain, Recycling XChain, Cannabis XChain and other Workflow solutions utilize blockchain technologies such as a public distributed ledger to provide traceability and transparency - to provide trust. Our XChain solution uses the same technologies to allow customers to track any asset - trees, recycled wind turbines, medical cannabis, carbon credits - anything!
