“…The scientific literature explores the issue of using blockchain technologies in the following areas of the digital economy, namely: the financial system at the macro and micro levels (in particular, financial and technological companies) (Vovchenko et al, 2017;Karapetyan et al, 2019), insurance system, public administration system (Babkin et al, 2017;Britchenko & Cherniavska, 2019), infrastructure (Abodei et al, 2019), e-commerce system, industry, agriculture (for supply chain management in agriculture) (Tripoli & Schmidhuber, 2018;Baralla et al, 2018;Sajja et al, 2021), intellectual property, education, health care (Dorofeyev et al, 2018;Muminova et al, 2020). Blockchain is also being actively implemented in the tourism sector, especially in island countries (Treiblmaier et al, 2020). For instance, the Caribbean countries have launched the first legal digital means of payment; Aruba has developed a blockchain platform in order to ensure the growth of tax revenues from tourism (Kwok & Koh, 2019).…”
