Enhancing Food (Turmeric) Supply Chain Transparency Using Automated Smart Contracts

Abstract

Food supply chains today face significant challenges, including inefficiencies, counterfeiting, and safety risks, largely due to inadequate traceability and transparency. This paper addresses these issues by leveraging a blockchain-based solution that utilizes Ethereum and smart contracts written in Solidity to document supply chain events-harvest, processing, shipping, and delivery-as an unalterable transaction. The proposed system was developed using a functional proof-of-concept web application in React.js and Web3.js to enable users to log in, authenticate, and access critical information such as product origin, transport conditions, and quality checks. This application fosters accountability and trust among all concerned. By conducting experimentation with the food based blockchain, this paper assesses the feasibility and explores challenges such as transaction fees, scalability, and system integration. The platform facilitates real-time information sharing, reduces reliance on intermediaries, and strengthens food safety practices. It provides all stakeholders with access to a single source of truth. In summary, this paper illustrates the pragmatic applicability of decentralized technologies in transforming supply chains.
