BLOCKCHAIN-BASED FARMER-TO-CONSUMER PLATFORM

Abstract

Small-scale farmers produce 60–70% of the food in the global agricultural supply chain, but they are exploited by middlemen who keep 50–80% of the profits, which drives up prices for consumers and puts farmers in poverty. In order to ensure fair pricing, transparency, and food security, this paper proposes a blockchain-based farmer-to-consumer platform that does away with middlemen. Direct trade, AI-driven crop recommendations, and UPI-based payments are all made possible by the platform, which was developed with Hyperledger Fabric for safe, impenetrable transactions and integrated with a Node.js and Firebase web application via ngrok. By lowering food waste, improving traceability, and supporting sustainable agriculture, the system supports SDG 2 (Zero Hunger). Diverse farmers can use it thanks to an intuitive interface that offers voice assistance and multilingual support. According to testing, the platform reduces post-harvest losses by 20% and achieves 98% transaction accuracy.
