APPLICATION OF GREEN BLOCKCHAIN AND ALGORAND ALGORITHM IN AGRICULTURAL PRODUCT TRACEABILITY: THE CASE STUDY OF COFFEE SUPPLY CHAIN IN VIETNAM

Abstract

Traceability has increasingly become a mandatory requirement in the export of agricultural products. Efforts in developing IoT and traditional software solutions, however, have not adequately met the growing demand for transparency and sustainability in supply chain. This study proposes the application of green blockchain technology for agricultural product traceability, with a case study focusing on the Vietnamese coffee supply chain. By employing the Proof of Stake (PoS) consensus mechanism and Algorand algorithm, the proposed model enables real-time data collection and ensures data immutability, transparency, and efficiency in information exchange among stakeholders. Additionally, this solution contributes to the digitization of the entire agricultural supply chain with minimal environmental impact, representing a significant development toward promoting the sustainability and competitiveness of Vietnamese agricultural products in the global market.
