The architecture of the SSI Kit consists of three layers:
- Low-Level Services Abstraction: Abstracts complex, low-level operations (e.g. cryptography, key management, digital signatures, data storage).
- Ecosystem Abstraction: Abstracts ecosystem-specific requirements based on the relevant technical and governance frameworks (e.g. SSI flavors, business logic, policies).
- High-Level Interfaces / APIs: Provides high-level interfaces that hide complexity and facilitate usage for developers.
Also, the architecture allows for the integration of third party solutions throughout the stack. For example:
- Key storage (e.g. HSM, WebKMS)
- Data storage (e.g. identity hubs, confidential storage)
- Registries (e.g. blockchains, DNS)
This architectural openness prevents vendor lock-in and allows you to build SSI-based solutions that meet your unique requirements.
