Establishing a Baseline for Evaluating Blockchain-Based Self-Sovereign Identity Systems: A Systematic Approach to Assess Capability, Compatibility and Interoperability

Self-Sovereign Identity (SSI) is an evolving means of identity management that aims to give individuals more control over their digital identities and personal data rather than relying on third-party organizations or government authorities. Blockchain technology has the potential to strengthen SSI significantly by providing a secure and decentralized method for managing and storing personal data, rendering them resistant to tampering and enhancing privacy. Given the diversity of blockchain-based SSI platforms, including Sovrin, uPort, and Hyperledger Indy, it is essential to have a consistent approach to evaluate different SSI systems. This paper offers guidelines for building systematic architecture and defining comprehensive internal interactions for a complete SSI system, providing a framework for routine evaluation and analysis of existing SSI platforms and establishing base standards for assessing capability, compatibility, and interoperability. The paper also reports on comprehensive experiments over many existing blockchain-based SSI systems using a multi-layered approach.
