The European Centre for Government Transformation convened the High-Level Roundtable on Tax and Revenue Collection in the Digital Age under the theme of How Artificial Intelligence and Blockchain Will Transform Public Service and Revenue Collection. The three-sessioned summit brought together an eclectic mix of high-level participants from, inter alia, Belgium, Estonia, Ireland, Italy and the United Kingdom, who presented case studies on the role and potential of artificial intelligence and blockchain-powered solutions for better tax collection and public-sector service provision.
