The need for transparency and traceability in the food supply chain has increased in an increasingly linked world, especially in smart tourism destinations where visitors are looking for real, sustainable, and safe food experiences. By establishing a decentralized, immutable ledger that tracks every transaction and movement of food products from farm to fork, blockchain technology transforms food traceability and guarantees that all parties involved farmers, processors, distributors, retailers, and consumers have access to accurate, up-to-date data. With only a quick scan of a QR code, consumers can verify the provenance and path of food, preventing fraud and boosting customer confidence. The real-time data collection and transmission of parameters like temperature, humidity, and location by IoT devices like sensors and RFID tags, which are then recorded on the blockchain to create an extensive and transparent record of the food product’s journey, is one way that the integration of blockchain technology with the Internet of Things (IoT) improves traceability systems even further. This technology guarantees that local food items in a smart tourism zone fulfill strict safety and quality criteria, boosting the area’s image and offering visitors reliable, genuine dining experiences. By utilizing blockchain technology and the IoT, intelligent tourist destinations may attain previously unheard-of levels of traceability and transparency in their food supply chains, satisfying the increasing needs of environmentally aware customers and encouraging sustainable practices that boost local economies. Using these technologies is a big step toward guaranteeing food authenticity, quality, and safety in a society that values transparency and interconnection.
