+\section{The GNU Name System In a Nutshell}
+\begin{frame}{Motivation}
+  \begin{itemize}
+    \item DNS remains a source of traffic amplification DDoS.
+    \item DNS censorship (i.e. by China) causes collateral damage in other countries.
+    \item DNS is part of the mass surveillance apparatus (MCB).
+    \item DNS is abused for offensive cyber war (QUANTUMDNS).
+    \item DoT/DoH, DNSSEC, DPRIVE unfortunately do \textbf{NOT} fix this.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{What is the GNU Name System?\footnote{Joint work with Christian Grothoff and Matthias Wachs}}
+  \begin{itemize}
+    \item Fully decentralized name system $\Rightarrow$ Names are not global.
+    \item Supports globally unique and secure identification.
+    \item Features query and response privacy.
+    \item Provides a public key infrastructure
+      \begin{itemize}
+        \item Each zone is associated with a cryptographic key pair.
+        \item Delegation between zones establishes trust relationship.
+      \end{itemize}
+    \item Interoperable with DNS.
+    \item Usable.\footnote{User studies conducted in ``Decentralized Authentication for Self-Sovereign Identities using Name Systems'' (DASEIN) project.}
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Applications}
+  \begin{itemize}
+    \item Identity management: \textbf{re:claimID} (\url{https://reclaim-identity.io})
+    \item Social Networks: \textbf{SecuShare} (\url{https://secushare.org})
+    \item Healthcare: \textbf{Accident insurance and private health data}.\footnote{Joint work with FH Bern, ``Decentralized Authentication for Self-Sovereign Identities using Name Systems'' (DASEIN)}
+    \item Others: \textbf{Chat}, \textbf{Host addressing}, \ldots

+\section{Technical Overview}
+\begin{frame}{Record Storage / Retrieval}
+  \begin{itemize}
+    \item GNS stores records in a \textbf{Distributed Hash Table} (DHT).
+    \item DHTs allow us to map keys to values.
+    \item Naive approach: Map domain names to records.\\e.g.: example.com $\Rightarrow$ A: 1.2.3.4
+  \end{itemize}
+  \begin{center}
+    \includegraphics[width=0.5\textwidth]{DHT.pdf}
+  \end{center}
+\end{frame}
+
+%\begin{frame}{Record Storage / Retrieval}
+%  \begin{itemize}
+%    \item GNS implements a \textbf{Private Information Retrieval} (PIR) scheme.
+%    \item DHT values (records) are signed and encrypted.
+%    \item DHT keys are derived from queried name and zone.
+%  \end{itemize}
+%  \begin{center}
+%    \includegraphics[width=0.5\textwidth]{DHT.pdf}

+%\end{frame}
+
+\begin{frame}{Secure Storage / Retrieval}
+   \begin{itemize}
+    \item \textbf{Query privacy}
+      \begin{itemize}
+        \item GNS implements a \textbf{Private Information Retrieval} (PIR) scheme:\\
+  ``a protocol that allows a user to retrieve an item from a server in possession of a database without revealing which item is retrieved.''\footnote{\url{https://en.wikipedia.org/wiki/Private_information_retrieval}}
+
+        \item Queries do not reveal domain name.
+        %item DHT keys are ``blinded'' record labels and zone identity.
+      \end{itemize}
+    \item \textbf{Record confidentiality}: Values in DHT are signed and encrypted by zone owner.
+    \item \textbf{Zone privacy}: Zones cannot be enumerated.
+    \item \textbf{Censorship and DDoS resistance}: Decentralized, resilient directory.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Zone Delegation}
+  \begin{itemize}
+    \item The ``NS'' equivalent in GNS is called ``PKEY''.
+    \item A ``PKEY'' record contains public zone keys.
+    \item The combination of a ``PKEY'' record value and a name allows users to
+      query records in a delegated zone.
+  \end{itemize}

+\begin{frame}
+  \includegraphics[height=0.9\textheight]{deleg3.pdf}
+\end{frame}
+
+
+\begin{frame}{The GNU Name System Root}
+  ``Hyper-hyper local root'' concept:
+  \begin{itemize}
+    \item Resolver ships with initial root zone configuration.
+    \item Root zone configurable \emph{locally} at \emph{each} endpoint.
+    \item User override/extension of root at top-level or subdomain-level for:
+      \begin{itemize}
+        \item Circumvent censorship if necessary.
+        \item Private networks.
+      \end{itemize}
+  \end{itemize}
+\end{frame}
+
+\begin{frame}{Envisioned Governance Model}
+  \begin{itemize}
+    \item Non-profit organization.
+    \item Multi-stakeholder model: Board, supporting organizations, \ldots
+    \item Examples for possible stakeholders:
+      \begin{itemize}
+        \item Software and OS Distributors
+        \item Browser vendors
+        \item Governments
+      \end{itemize}
+    \item Funding options:
+      \begin{itemize}
+        \item Applications for new top-level domains.
+        \item Registrations of new top-level domains.
+        \item \ldots
+      \end{itemize}

+\section{Quo Vadis?}
+\begin{frame}{Roadmap}
+  \begin{itemize}
+    \item In progress:
+      \begin{itemize}
+        \item 2019-2020: Technical specification of GNS protocol, packaging and alternative implementations.\footnote{Funded by NLnet under EU Next Generation Internet program (\url{https://nlnet.nl/project/GNS/}).}
+        \item Continuous development and integration into applications.
+      \end{itemize}
+    \item 2020--: Establishment of governing body.
