To offer more transparency, retail stores, in collaboration with meat producers, may soon use the emerging technology of Blockchain.You may have already heard about Blockchain since it is strongly associated with Bitcoin, the famous cryptocurrency. Currently, Blockchain has been used successfully for cryptocurrencies and financial services, and it could be soon applied for food processing. The Blockchain is a shared database whose critical feature is to be immutable and easily auditable. Once data is registered into the Blockchain it can’t be removed or modified. This immutable ledger is shared between multiples writers, which would include producers, retail stores, and food companies. In practice, the idea would be to use this shared database to record several pieces of information about a piece of food such as:
- The origin
- The various owners, including the factory and the producer
- Its storage temperature
- Its expiration dates
- Its shipping dates
