Master's Thesis: Development of an Implementation-based Evaluation Framework for Verifiable Credential SDKs
Current literature on SSI has only a small focus on developers. This thesis gives developers a handful of useful tools to integrate SSI into their projects:
- 👀 Overview over 15 SSI solutions and their coverage of the Verifiable Credential lifecycle
- 🚀 Reference implementation for Mattr, Trinsic, Veramo and Azure AD for Verfiable Credentials
- 🧮 New evaluation framework covering functionality, flexibility, operability, dependency, and involvement
Comes as a RESTful API written in TypeScript using Express that implements the Verifiable Credential lifecycle of selected solutions. Based on the vc-http-api.
Shows, to what extend the solutions cover the Verifiable Credential lifecycle.
- Direct coverage: API exposes functionality to implement a percentage of the lifecycle
- General coverage: Includes direct coverage and abstracted steps of the lifecycle that is not exposed via an API
| Process Steps | MATTR | Veramo | Trinsic | Azure AD for VCs |
|---|---|---|---|---|
| Direct Lifecycle Coverage | 60% | 90% | 40% | 20% |
| General Lifecycle Coverage | 90% | 90% | 90% | 80% |
Descriptions of all categories, criteria, and questions can be found in the thesis. All categories are normalized to have equal weight in the final score. Custom weights have to be applied by the developer dependeing on their use case.
| Category | Mattr | Veramo | Trinsic | Azure AD for VCs |
|---|---|---|---|---|
| Functionality | 93% | 65% | 58% | 38.83% |
| Flexibility | 25% | 83.33% | 41.67% | 25% |
| Operability | 81.25% | 35.43% | 72.92% | 50% |
| Dependency | 20% | 100% | 20% | 20% |
| Involvement | 100% | 100% | 100% | 100% |
| Normalized Score | 63.85% | 76.75% | 58.52% | 46.77% |
