Abstract
This systematic review is a trailblazer for the blockchain-based sharing economy concept, mainly for hospitality and tourism. It highlights the potential integration of blockchain across sharing economy sectors (e.g., accommodation, transportation, and business services). Following the PRISMA protocol, 43 publications from 12 scholarly databases were analysed. It identifies different types of implementations, including decentralised apps and specific functionalities that utilise blockchain. Key issues are discussed, including contradictory aspects (transparency vs privacy, centralisation within decentralisation, and users' euphoria vs technical barriers) and advantages (increased security, automated sharing mechanisms, and user participation). The review offers practical implementation paths for blockchain-based sharing economy systems in hospitality and tourism, emphasising the importance of context, scope limitation, focusing on increasing advantages, and managing technological trade-offs. It also suggests critical future research topics and action agendas for hospitality and tourism stakeholders.
