Request food online is daily present in the life of people, however, it is necessary to send delivery information to different restaurant systems and sometimes these restaurants share customer sensitive information with their partners without the authorization of the customer creating a security risk with customers data. Also, in most cases when a person travels to a different country and wants to request food online, it is necessary to use the local currency, requiring a currency exchange operation. This paper evaluates a proof-of-concept (POC) of the integration of blockchain in the food industry, allowing customers to order food online through a sidechain, an exclusive blockchain with specific custom transaction types for restaurants. The FoodTransaction type is responsible to order food and store cryptographically customer sensitive information that only the customer itself and the requested restaurant can read, hence it respects customer privacy. Furthermore, the blockchain cryptocurrency can be used anywhere in the world. The performance evaluation shows a great advance in throughput when compared to the use of the payment solution on Bitcoin applications. Finally, the results show the possibility to extend the restaurant sidechain business to several restaurants in the world and in different time zones.
