+\begin{frame}{What is Taler?}
+ \framesubtitle{\url{https://taler.net/en/features.html}} \noindent
+Taler is
+ \vfill
+ \begin{itemize}
+ \item a Free/Libre software \emph{payment system} infrastructure project
+ \item ... with a surrounding software ecosystem
+ \item ... and a company (Taler Systems S.A.) and community that wants to deploy it
+ as widely as possible.
+ \end{itemize}
+ \vfill
+\noindent
+ However, Taler is
+ \begin{itemize}
+ \item \emph{not} a currency or speculative asset
+ \item \emph{not} a long-term store of value
+ \item \emph{not} a network or instance of a system
+ \item \emph{not} decentralized
+ \item \emph{not} based on proof-of-work or proof-of-stake
+ \end{itemize}
+\end{frame}
+
+
+\begin{frame}{Design principles}
+ \framesubtitle{https://taler.net/en/principles.html}
+GNU Taler must ...
+\begin{enumerate}
+ \item {... be implemented as {\bf free software}.}
+ \item {... protect the {\bf privacy of buyers}.}
+ \item {... enable the state to {\bf tax income} and crack down on
+ illegal business activities.}
+ \item {... prevent payment fraud.}
+ \item {... only {\bf disclose the minimal amount of information
+ necessary}.}
+ \item {... be usable.}
+ \item {... be efficient.}
+ \item {... avoid single points of failure.}
+ \item {... foster {\bf competition}.}
+\end{enumerate}

+\begin{frame}{NGI TALER PILOT}
+\framesubtitle{\url{https://taler.net/en/consortium.html}}
+
+ \begin{itemize}
+ \item EU Project started December 2023 to deploy GNU Taler
+ \item 3 financial institutions (GLS Bank, Magnet Bank, Visual Vest),
+ 2 academic institutions (Berner FH, TU Eindhoven), 3 SMEs (Taler Systems SA, Code Blau GmbH, Petit Singularites), 3 non-profits (NLnet Foundation, E-Seniors Association, Homo Digitalis)
+ \item $\approx$ \EUR 5M budget over 3 years
+ \item Objective: {\bf Deploy GNU Taler in Europe}
+ \end{itemize}
+\end{frame}
+
+
+\begin{frame}{Key NGI PILOT Activities}
+ \begin{itemize}
+ \item Integration (core banking, online publishers, e-commerce, public transportation)
+ \item Compliant (establish compliance processes at each bank)
+ \item Availability (packaging, porting to more platforms, browsers)
+ \item Hardware support (offline payments, vending machines)
+ \item Security audits of code and design
+ \item Accessible (old people, children, blind users)
+ \item Future-proof (post-quantum, standardized)
+ \item Widely known and used (community building, open calls)
+ \end{itemize}
