Abstract
Agricultural supply chains face persistent challenges of opacity and fraud. Using Hyperledger Fabric across 200 smallholder farmers in three countries, we demonstrate 68% faster transaction verification and 54% faster dispute resolution.
Agricultural supply chains face persistent challenges of opacity, fraud, and inefficiency that undermine food security and farmer livelihoods. This paper proposes and evaluates a blockchain-based traceability framework designed to enhance transparency from farm to consumer. Using a permissioned Hyperledger Fabric network deployed across a pilot supply chain involving 200 smallholder farmers in three countries, we demonstrate measurable improvements in transaction verification speed (68% reduction), dispute resolution time (54% reduction), and farmer income through elimination of intermediary fraud.
