Abstract

Blockchain is the core technology behind several revolutionary applications that require consistent and immutable Distributed Ledgers, maintained by multi-party authorities. Examples of such applications include cryptocurrencies, smart contracts, Self Sovereign Identity (SSI) and Edge/Fog-enabled smart systems (eHealth, IIoT, IoV, etc.). Hyperledger Indy and Aries are suitable open-source tools for permissioned blockchain utilization in SSI projects. Those two frameworks have gained much attraction by researchers interested in the topic, while continuously maintained under the umbrella of the Linux Foundation. However, some SSI applications require specific upper bound of response time depending on their business model. In this paper we aim at presenting a detailed latency analysis of Indy, on top of which Aries is typically built. With such an architecture, researchers and practitioners of SSI applications can decide whether this framework fulfills their application requirements. To realize our proposed architecture, we have developed a Python application with containerized Indy and Aries components. Its scripts use and build on the official open-source codes of the Hyperledger repositories. We have deployed our application on multiple virtual machines in the Google Cloud Platform, and evaluated it with various scenarios. Depending on the transaction rate, we found that the writing response latency of an Indy-based blockchain containing 4 and 8 nodes, ranges between 1–16 seconds, while the reading response latency with similar settings ranges between 0.01–5 seconds.
