+<h1>2022-6: &quot;GNU Taler Scalability: Measuring and Improving the 
Performance of GNU Taler on Grid’5000&quot;</h1>
+
+<h2>Background</h2>
+<p>
+Anonymity loves company. Hence, to provide the best
+possible anonymity to GNU Taler users, the scalability of
+individual installations of a Taler payment service matters.
+While our design scales nicely on paper,
+<a href="https://www.ngi.eu/ngi-projects/fed4fire/";>NGI Fed4Fire+</a>
+enabled us to evaluate the transaction rates that could be achieved
+with the actual implementation.  Experiments were conducted by Marco Boss for
+his Bachelor's thesis at the <a href="https://www.bfh.ch/";>Bern
+University of Applied Sciences</a> to assess bottlenecks and suggest
+avenues for further improvement.
+</p>
+
+<h2>Abstract</h2>
+<p>
+This thesis is on the GNU Taler scalability experiments conducted
+on <a href="https://www.grid5000.fr/";>Grid’5000</a> in the first
+half of 2022, which was preceded by preparations carried out in the second 
half of 2021
+supported by the Next Generation Internet initiative’s
+<a href="https://www.ngi.eu/ngi-projects/fed4fire/";>NGI Fed4Fire+</a> program.
+<br>
+The primary goal of this study was to evaluate the scalability of GNU Taler in 
a real-world
+scenario. That is, moving away from the loopback system to a distributed 
network and identifying
+improvement opportunities therein to analyze and improve performance. While the
+basic framework was already known from the previous study, this work focuses 
on extending
+the framework and making further improvements to GNU Taler. This includes, 
among
+other things, the horizontal distribution of the PostgreSQL database.
+<br>
+We identified and fixed several bottlenecks in the GNU Taler software. We 
parallelized the
+execution of the cryptographic frontend, leaving the PostgreSQL database as 
the natural bottleneck.
+Here, we optimized queries and modified the schema to enable table 
partitioning.
+The scalability demonstrated in our experiments shows that Taler is very 
capable of processing
+enough transactions per second to be considered an acceptable payment system.
+Throughout this work, we were able to increase the performance of Taler by a 
factor of 95,
+from about 300 to 28.5k transactions per second, showing that Central Bank 
Digital Currencies
+based on Taler would require only a few exchanges per continent.
