Performance Evaluation of Self-Sovereign Identity Use Cases

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; to do this, we implemented healthcare use cases using Hyperledger Indy and Hyperledger Aries frameworks, deployed it in a cloud environment, and executed their 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.
