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 iden-
-tifying improvement opportunities therein to analyze and improve performance. While the
-basic framework was already known from the previous study, this work focuses on extend-
-ing the framework and making further improvements to GNU Taler. This includes, among

other things, the horizontal distribution of the PostgreSQL database.

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 bot-
-tleneck. 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 pro-
-cessing 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 Curren-
-cies based on Taler would require only a few exchanges per continent.
