The European Union has opened applications for the blockchain regulatory sandbox, which aims to promote cross-border dialogue between regulators on the one hand and between companies or public authorities on the other. The blockchain sandbox will run until 2026 and will support 20 projects involving blockchain applications each year for use by the public and private sectors. The first application deadline is April 14, and a panel of independent academic experts will select projects. This application is open to companies from all industries as well as public entities.
