An Ecosystem for the Dairy Logistics Supply Chain with Blockchain Technology

In 2020, the annual consumption of fluid cow milk worldwide was 81 million tons, and the use of dairy products was 222.5 billion pounds [1]. However, in such a big dairy market, the supply system has had a series of problems including diarrheal disease which causes 760,000 childhood deaths annually [2]. Among all the reasons, food fraud, illegal production, and foodborne illness are critical. This paper presents a brand new dairy logistic supply ecosystem with blockchain technology. Taking advantage of many attributes of blockchain such as decentralization, security, and transparency, it solves the problems mentioned above that the centralized dairy supply systems cannot solve. The blockchain approach guarantees to provide customers with fresh and safe dairy products at fair prices. All the data in the system is open to all participants and the Internet of things (IoT) lowers the labor and decrease errors. The most important attribute is its smart contracts with crowdfunding function, with which an eco-society is created. We finally discuss the difference between the e-commence model in the Internet and eco-commence model in the Blockchain. Which system is the future? The answer is waiting for us to dig out.
