Named ssi-sdk, this SDK encapsulates a set of standards related
to Self Sovereign Identity.
The ssi-sdk intends to provide flexible functionality based on a set of standards-based primitives for building
decentralized identity applications in a modular manner: with limited dependencies between components.
The image above outlines the SDK's vision. Standards may be added and/or removed. The standards themselves are under active development, and as such, are subject to change. When possible we aim to call out which versions or revisions of standards we are building implementations against.
The SDK has not undergone any formal security review or audit, so please use with caution.
This project is fully open source, and we welcome contributions! For more information please see CONTRIBUTING. Our current thinking about the development of the library is captured in GitHub Issues.
