-\section{What is GNU Taler?}
-\begin{frame}{What is GNU Taler?}
-  \vfill
-  \begin{center}
-GNU Taler is an electronic instant payment system.
-  \end{center}
-  \begin{itemize}
-  \item Uses electronic coins stored in {\bf wallets} on customer's device
-  \item Think electronic {\bf cash}, with a few twists
-  \item Pay in {\bf existing currencies} (i.e. EUR, USD, BTC)
-%    or use it to create new regional currencies
-  \end{itemize}
-  \vfill
-  \begin{center}
-    Taler is {\bf not} a cryptocurrency.

-\frametitle{Components in Depth}
-\begin{itemize}
-\item Exchange: payment service provider
-  \begin{itemize}
-  \item Wire plugins: integration with register based system
-  \item Database plugins: persist cryptographic proofs
-  \item Auditor: verifies correct operation
-  \end{itemize}
-\item Wallet: customer user interface
-  \begin{itemize}
-  \item Browser extension
-  \item E-mail client integration (future work)
-  \item NFC payments (future work)
-  \end{itemize}
-\item Merchant: shop
-  \begin{itemize}
-  \item Front end (custom)
-  \item Backend (RESTful service, performs cryptography)
-  \item Backend database: persists cryptographic proofs
-  \item Back office Web service: access to business data
-  \end{itemize}
-\item Protocol specification (generally JSON-based)
-\end{itemize}

-\begin{frame}{Hardware requirements}
-\begin{itemize}
-\item[@] Exchange:
-  \begin{itemize}
-    \item high-availablility data center (with replicated database),
-    \item expected amortized average transaction costs $\approx$ \EUR{0.000001}
-    \item transaction latency $\approx$ network RTT
-  \end{itemize}
-\item[@] Merchant:
-  \begin{itemize}
-  \item database to store contracts and cryptographic proofs
-  \item minimal CPU, hardware and bandwidth requirements
-  \item integration cost small due to reusable backend and backoffice components
-  \end{itemize}
-\item[@] Customer:
-  \begin{itemize}
-  \item database (IndexedDB) to store coins, contracts and cryptographic proofs
-  \item minimal CPU, hardware and bandwidth requirements
-  \item DesignShift estimated \EUR{300,000} cost for design of
-        mass production ready \EUR{10} NFC hardware wallet in CC format
-  \end{itemize}
-\end{itemize}
-\end{frame}

-\begin{frame}{Availability / Reliability / Off-line transactions}
-
-  {\bf CAP theorem:}
-\begin{center}
-  Consistency, Availability, Partition-Tolerance: pick two!
-\end{center}
-\vfill
-\begin{itemize}
-\item By default, Taler focuses on consistency and detects double-spending online \\
-      $\Rightarrow$ Network partitions impact availability
-\item Sharing coins via NFC while offline in principle possible \\
-     $\Rightarrow$ Double spending detected late, receiver may be defrauded
-\end{itemize}
-\vfill
-\end{frame}
-
-
-\begin{frame}{Security}
-\begin{itemize}
-\item Each party must keep their private keys secure
-%\item Private keys are never disclosed by the protocol (not even during payments)
-\item Losses are by design with party where keys were compromised
-\item Losses are bounded to:
-\begin{itemize}
-\item amount of coins carried in wallet (for consumer)
-\item volume of transactions during compromise (for merchant)
-\item amount of coins in circulation (for exchange)
-\end{itemize}
-\item Denomination key expiration used to limit risk
-\item Exchange operator typically has escrow account matching issued coins
-\end{itemize}
-\end{frame}
-
-
-\begin{frame}{Scalability}
-  \begin{block}{By design}
-  For exchange operator:
- \begin{itemize}
-  \item linear scalability (via sharding) of database
-  \item linear scalability of cryptographic operations
- \end{itemize}
- System also supports having multiple exchange operators.
-  \end{block}
-  \begin{block}{Implementation limitations}
-    \begin{itemize}
-    \item Auditor implementation is currently sequential
-    \end{itemize}
-  \end{block}
-  All components are {\em free software} with {\em public specifications}.
-\end{frame}
-
-
-\begin{frame}{Interoperability}
- \begin{itemize}
-  \item Database layer abstracted via interface
-  \item Wire transfer layer abstracted via interface
-  \item Open protocol specification
-  \item RESTful JSON-based APIs
-  \item Designed to operate well with HTTP(S)
-  \item Recent changes to better support Apps and non-WebExtension compatible browsers
-  \item Core logic implemented in portable C code (exchange, merchant backend)
-  \item Wallet-specific logic implemented in TypeScript \\
-        ($\Rightarrow$ WebExtensions, React)
- \end{itemize}
-\end{frame}
-
-
-\begin{frame}{Reliability}
- \begin{itemize}
-  \item Cryptographic constructions are well-understood
-  \item Cryptographic primitives are state-of-the art
-  \item Protocols have been peer-reviewed by various cryptographers
-  \item State-of-the-art secure software development process
-  \item Implementation has been (partially) subjected to security audits, more planned
-  \item World-class information security team
- \end{itemize}
-\end{frame}
-
-
-\begin{frame}{Anonymous transactions}
-\begin{itemize}
-\item Customer must identify when withdrawing via register system (KYC)
-\item Merchant must identify to receive via register system (AML)
-\item Merchant can be compelled to disclose terms of contract
-\item Customer can be {\em anonymous} when paying
-\item Multiple transactions of same customer are {\em unlinkable}
-\item Customer has proof of purchase
-\item Customer can voluntarily disclose identity, but not be compelled
-\item Exchange operator must be well-known and certified by auditor
-\item Auditor keys usually hard-coded in customer and merchant software
-\end{itemize}
-\end{frame}
-
-
-\begin{frame}{Identity Management}
- \begin{itemize}
-  \item Taler provides electronic cash on top of register-based system
-  \item Typically, customer and merchants have accounts in register-based system \\
-        $\Rightarrow$ Identification piggy-backs on register-based system
-  \item Customer's wallets have a key to identify them
-  \item Possible to send electronic coins to customer based on wallet key \\
-        $\Rightarrow$ Possible to provide {\em welfare} to unbanked individuals
-  \item Receiving Taler payments requires account in register (for taxability)
- \end{itemize}
-\end{frame}
-
-
-\begin{frame}{Accessibility}
- \begin{itemize}
- \item Anyone can customize wallet, as {\em protocols} enforce security!
- \item Wallets (HW, SW) will be customized to
-       match accessibility requirements (children, disabled, elderly)
- \item Prototype was publicly demonstrated and explained by 10 year
-       old kid at hacker conferences (videos available)
- \item Transaction speed is one click plus network RTT
- \item Avoiding customer authentication improves privacy and usability!
- \item Advisory board voiced ethical concerns with payments becoming
-       too easy and need to integrate financial education with wallet.
- \end{itemize}

-    \begin{itemize}
-        \item{Replace Mastercard/Visa/Paypal online} \\
-              $\Rightarrow$ Cheaper transactions $\equiv$ 3\% reduction in VAT
-        \item{Replace cash and credit cards} \\
-              $\Rightarrow$ Faster business transactions in stores
-        \item{Income via Taler is easily tracked by the government} \\
-              $\Rightarrow$ Less corruption, less tax evasion possible
-        \item{Nobody can track how you spend your money} \\
-          $\Rightarrow$ Privacy for citizens! \\
-          $\Rightarrow$ Industrial espionage defense for business!
