Employ Blockchain Technology into Smart Agriculture: Tracking Crops, Sharing Data Securely with the Internet of Things and Distributed Ledgers

Abstract

Smart agriculture transforms food security, climate change, and resource optimization. In agriculture, IoT monitors soil, crop, irrigation, and supply chain operations in real time. As data-driven farming expands, stakeholders face security, transparency, trust, and interoperability issues. Centralized agricultural data management systems are unreliable due to tampering, illegal access, and single points of failure. Smart agriculture uses blockchain technology for secure crop tracking and data sharing via distributed ledger systems. The suggested architecture enables data immutability, traceability, and transparency across the agricultural lifecycle with IoT-enabled sensing and blockchain-based data storage and validation. Secure crop origin, cultivation, and logistics information is available to farmers, distributors, regulators, and consumers. Blockchain-supported smart agriculture enhances stakeholder trust, fraud reduction, and decision-making efficiency, studies show. The decentralized design allows resilient data exchange without centralization. We found that blockchain and IoT can modernize agricultural ecosystems, promote sustainable farming, and improve food supply chain integrity. This research develops secure, transparent, and intelligent digital agriculture systems.
