Cross-Border Blockchain Transactions as a Tool for Adapting the National Economy of the Russian Federation to International Sanctions

In this study, we focused on the mechanisms for ensuring the sustainable development of the Russian economy in the context of correction of external financial flow owing to the adjustment of foreign economic supply chains. By constructing a system of recursive equations, it was established that a 1% reduction in volume of transnational financial flow creates the potential for a 0.45% decrease in Russia's gross domestic product. The localization of these risks can be achieved by implementing blockchain technologies in the Russian system of cross-border payments to provide a new foundation for financial flow under emerging systemic transformations in the external environment.
