IBM proposes using IoT and blockchain technology to track food deliveries from farm to table and ensure food safety. Key elements include business networks where participants are known and identified, smart contracts governing asset transactions recorded immutably on a shared ledger, and IoT sensors connecting devices at each stage to provide real-time data access. Developers can get started using free IBM Cloud services for IoT, blockchain, and a Node-Red flow editor to prototype solutions.
