Self-sovereign identity (SSI) enables the creation of user-centric applications where the user has complete control over his data. This research evaluates the performance of SSI-based applications. This work proposed an architecture based on the Hyperledger Indy and Hyperledger Aries frameworks, deployed it in a cloud environment, and executed its empirical evaluation. The results indicate that the bottleneck is the CPU; a simple setup can support up to 80 concurrent users without relevant errors and 120 simultaneous users before system degradation. Finally, we discuss the system bottlenecks and possible optimization techniques.
