Blockchain technology is redefining agriculture by enhancing transparency, efficiency, and sustainability across food supply chains. Its decentralized and immutable nature ensures traceability, improves food safety, and reduces inefficiencies, enabling stakeholders to monitor every step from farm to fork. Smart contracts streamline transactions, reduce intermediaries, and promote fair trade, empowering small-scale farmers and fostering financial inclusion. Additionally, blockchain supports sustainability by enabling precise tracking of carbon footprints, water usage, and soil health metrics. Despite its transformative potential, challenges such as technological adoption barriers, high costs, and regulatory complexities persist. This paper examines the applications, benefits, and future implications of blockchain in agriculture, emphasizing its role in achieving sustainable and resilient agricultural systems
