Architecture

The architecture of the SSI Kit consists of three layers:

1. Low-Level Services Abstraction: Abstracts complex, low-level operations (e.g. cryptography, key management, digital signatures, data storage).

2. Ecosystem Abstraction: Abstracts ecosystem-specific requirements based on the relevant technical and governance frameworks (e.g. SSI flavors, business logic, policies).

3. 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.

Illustration:

The blue boxes symbolise our products and their interfaces. The green boxes symbolise third party solutions that can be integrated via open APIs to avoid rip-and-replace and extend functionality to meet diverse customer requirements.
