Covid-19 Antigen Test Kit Distribution System Based-on Blockchain Technology

Abstract

Transparency is the primary component of developing trust to ensure the integrity of the supply chain. Each business must provide information and contribute to its supply chain. One of the many products that have been brought out during the pandemic is COVID-19 ATK (Antigen Test Kits) which must be used almost constantly in many situations. In recent years a technology known as blockchain attracted the attention of many individuals. Blockchain is an advanced database mechanism that allocates data within a decentralized system. This paper explores the efficiency of blockchain technology in enhancing supply chain transparency to ensure the quantity of COVID-19 ATK and to simplify the supply chain management experience by using Web 3.0. The proposed system uses smart contracts to record the transaction since the product has been manufactured and transferred across the supply chain network. The customer can ensure the integrity of the product by entering the product’s details, lot id, and expiration date, into the blockchain system to query the supply chain history. The system can detect many abnormalities, such as counterfeit, modified, and smuggled products.
