Blockchain-Based Soybean Traceability in Agricultural Supply Chain

TLDR

Globalized agriculture production and distribution highlight safety, quality, and validation challenges, driving a need for effective traceability solutions such as blockchain to manage complex, multi‑stakeholder supply chains. The study proposes using Ethereum blockchain and smart contracts to enable soybean tracking and traceability across the agricultural supply chain. The system employs smart contracts to govern all participant interactions, recording transactions on an immutable blockchain linked to IPFS for transparent, traceable supply‑chain data. The solution eliminates centralized authorities and intermediaries, delivering high‑integrity, reliable, secure transaction records that improve efficiency, safety, and traceability.

Abstract

The globalized production and the distribution of agriculture production bring a renewed focus on the safety, quality, and the validation of several important criteria in agriculture and food supply chains. The growing number of issues related to food safety and contamination risks has established an immense need for effective traceability solution that acts as an essential quality management tool ensuring adequate safety of products in the agricultural supply chain. Blockchain is a disruptive technology that can provide an innovative solution for product traceability in agriculture and food supply chains. Today's agricultural supply chains are complex ecosystem involving several stakeholders making it cumbersome to validate several important criteria such as country of origin, stages in crop development, conformance to quality standards, and monitor yields. In this paper, we propose an approach that leverages the Ethereum blockchain and smart contracts efficiently perform business transactions for soybean tracking and traceability across the agricultural supply chain. Our proposed solution eliminates the need for a trusted centralized authority, intermediaries and provides transactions records, enhancing efficiency and safety with high integrity, reliability, and security. The proposed solution focuses on the utilization of smart contracts to govern and control all interactions and transactions among all the participants involved within the supply chain ecosystem. All transactions are recorded and stored in the blockchain's immutable ledger with links to a decentralized file system (IPFS) and thus providing to all a high level of transparency and traceability into the supply chain ecosystem in a secure, trusted, reliable, and efficient manner.
