Using blockchain technology offers new opportunities in the tourism industry, primarily when focusing on local communities. This chapter identifies the workings of blockchain, focusing on theories, proposing the implementation of direct P2P transactions, smart contracts, and the concept of sustainable and responsible tourism. Blockchain eradicating intermediaries decreases the control of local service providers, helps them gain access to the international market, and gets a proper recompense. Besides, tokenizing assets and services offers the market new ways of crowdfunding and resource management. Further study areas should be oriented toward enhancing digital accessibility, fostering favourable regulatory policies, evaluating the effectiveness of the blockchain's implementation in local economies and investigating cross-platform integration with miscellaneous advanced technologies. Finally, the blockchain can open a new future for tourism development where local communities will be real gatekeepers of their lands in the contemporary globalization environment.
