The digitisation of public administration is associated with high expectations. This also applies to the innovation and technology fields of artificial intelligence (AI) and distributed ledger technology (DLT). The task areas for AI applications in public administration are manifold. So far, however, only little use has been made of the opportunities involved. In the context of public administrative action, DLT applications are particularly appropriate for the management of transaction and process data, such as those occurring in register administration. International practical examples show that AI and DLT projects have become a regular service of public administrations. These projects include both individual applications, such as automatic traffic control, and the introduction of complex digital infrastructures as a basis for administrative services. The introduction and use of AI and DLT in public administration is not merely a technical issue. Established processes as well as the organisational and service culture of public administration must be adapted. Moreover, specific knowledge must be built up and networked. The interdepartmental digital challenges require a clarification and simplification with regard to the responsibility for the targeted expansion of technology strategies focusing on AI and DLT.
