Blockchain and IoT Integration in Dairy Production to Survive the COVID-19 Situation in Sri Lanka

Abstract

The epidemic crises place massive burdens on our economies. The risk of food supplies is also pushing massive stress on food vendors around the world. There are big problems associated with supply chains framework. Farmers do not receive payment upon delivery of their supplies. The buyers do not have access to finance that will enable them to pay farmers on time. To solve this problem, the authors proposed a dairy production system integration with blockchain and IoT. Blockchain is a decentralized digital ledger technology that allows network participants to trust each other and interact. The dairy product system can check the temperature of the product in real-time by using the website application. Moreover, customers can get notifications when the policy found problems related to temperature values. The blockchain database confirms the information security of the system by using the proof of work algorithm to create the transactions and the blocks. Therefore, the proposed methods can use sensitive data with reasonable time consumption, and no block creation fees are needed.
