The travel industry is transforming quickly, harnessing the most recent technologies to facilitate efficiency, safety, and transparency. Blockchain technology has emerged as a game changer with decentralized solutions to enhance operations, trust, and customer experience. With its capability to support immutable, distributed, and verifiable records, blockchain can potentially eradicate fraud, simplify transactions, and enhance supply chain management. This chapter addresses blockchain's primary trends and breakthroughs in tourism, such as smart contracts, safe payment, decentralized identity, and supply chain transparency. It also looks into the challenges and potential futures of blockchain applications within the industry. Further integration with artificial intelligence (AI) and the Internet of Things (IoT) increases blockchain’s applications within tourism further by making processes efficient, secure, and more accessible. Based on case studies and field applications, the chapter hopes to present a holistic image of the revolutionary role in forming the future of tourism.
