-\begin{frame}{Requirements: Online vs. Offline Digital Currencies}
-\framesubtitle{\url{https://taler.net/papers/euro-bearer-online-2021.pdf}}
-\begin{itemize}
-    \item Offline capabilities are sometimes cited as a requirement for 
digital payment solutions
-    \item All implementations must either use restrictive hardware elements 
and/or introduce
-      counterparty risk.
-    \item[$\Rightarrow$] Permanent offline features weaken a digital payment 
solution (privacy, security)
-    \item[$\Rightarrow$] Introduces unwarranted competition for physical cash 
(endangers emergency-preparedness).
-  \end{itemize}
-  We recommend a tiered approach:
-      \begin{enumerate}
-        \item Online-first, bearer-based digital currency with Taler
-%        \item (Optional:) Limited offline mode for network outages
-        \item Physical cash for emergencies (power outage, catastrophic cyber 
incidents)
-      \end{enumerate}

 \begin{frame}{Scalability}
 On paper, the design scales linearly with computing resources:

+\begin{frame}{Main Points}
+  \framesubtitle{\url{https://taler.net/}}
+Our CBDC:
+\begin{itemize}
+\item is token-based (no accounts), centrally issued (not DLT); as efficient 
and cost-effective
+as modern real-time gross settlement (RTGS) systems operated by central banks;
+\item is designed to provide an electronic equivalent to banknotes, therefore 
no material
+impact on monetary policy and/or financial stability expected;
+\item guarantees privacy for the payer, combined with KYC/AML/CFT compliance 
and
+income transparency to ensure taxes are paid;
+\item is implemented as Free/Libre and Open Source Software (FLOSS) to provide
+transparency, accountability, and security (part of the GNU project).
+\end{itemize}
+\end{frame}
+
+
+\begin{frame}{Taler for Programmable Money}
+  Relevant Taler core features:
+  \begin{itemize}
+    \item Taler coins are public-private key pairs. Buyers use them to 
digitally sign contracts.
+    \item Merchants have public-private key pairs to sign contracts.
+    \item RTGS transactions are associated with a wallet using a 
public-private key pair.
+    \item Core operations all yield externally verifiable cryptographic proofs!
+  \end{itemize}
+  Simple programmable features:
+  \begin{itemize}
+    \item Partial spending of a coin's value
+    \item Merchants refunding (anonymous) consumers
+    \item Merchants requesting aggregated payments to reduce RTGS costs
+  \end{itemize}
+\end{frame}
+
+
+\begin{frame}{Taler for Programmable Assets}
+  We have detailed protocol designs for:
+  \begin{itemize}
+    \item Privacy-preserving age-restrictions on coins
+    \item Pay for spam: automated payment requests, payments and refunds to 
fight unsolicited messaging.
+  \end{itemize}
+  We have plans for:
+  \begin{itemize}
+    \item Secure auctions (currency conversion, stock trading, E-bay)
+    \item Dividend distribution for coins representing shares
+    \item Shareholder voting in corporate decision making
+  \end{itemize}
