+\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 consortium (NGI TALER) 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}

+ \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}.}

+ {\bf GNU Taler:} \\
+ \begin{itemize}
+ \item Payment with one-time {\bf tokens}
+ \item Cryptographic privacy for payer
+ \item Suitable for children, tourists, ...
+ \item Free and Open Source
+ \item Deployed by community

+ {\bf Digital Euro:}\\
+ \begin{itemize}
+ \item Payment using bank {\bf accounts}
+ \item Privacy by policy, linkable payments
+ \item Requires ability to open bank account
+ \item ECB-proprietary
+ \item 10 years behind SOA

+\begin{frame}{Digital Euro}{Dangerous decisions}
+ \begin{itemize}
+ \item {\bf Offline requirement} assumes copy-protection unbreakable by NSA \& FSB
+ \item {\bf Waterfall} link to bank account implies compromised to Digital Euro
+ account also compromises linked bank accounts
+ \item {\bf Lack of privacy} enables absolute control of central bank over
+ private finances
+ \item {\bf Direct competition} for bank accounts and traditional payment
+ services disrupts banking sector financial stability
+ \item {\bf Non-FLOSS} solution limits interoperability and international
+ adoption
