BLOCKCHAIN TRACEABILITY MODEL IN THE COFFEE INDUSTRY

Abstract

The global coffee supply chain faces significant challenges in ensuring transparency, traceability, and trust among stakeholders, from farmers
to consumers. Traditional systems often suffer from inefficiencies, data fragmentation, and vulnerability to fraud. This paper proposes a
blockchain-based approach to enhance traceability and accountability in the coffee supply chain. By leveraging the decentralized, immutable,
and transparent nature of blockchain technology, the proposed system records every transaction and transformation of coffee—from cultivation
and harvesting to processing, distribution, and retail. Smart contracts automate verification and compliance with quality standards, reducing
the need for intermediaries and increasing operational efficiency. The system also empowers consumers with verifiable information about the
origin, journey, and sustainability practices associated with their coffee purchases. A prototype implementation demonstrates the feasibility
and effectiveness of the approach, highlighting improvements in data integrity, trustworthiness, and end-to-end visibility. This work contributes
to advancing sustainable and ethical practices in the coffee industry through technological innovation.
