zkSSI: The Zero-Knowledge Multiple-Condition Self-Sovereign Identity Framework

This project illustrates the implementation of the zkSSI framework. zkSSI allows on-chain and off-chain verifiers to specify attribute-based access control policies. Holders can obtain verifiable credentials from issuers. Then, the holders can generate the zero-knowledge verifiable presentation of their credentials to prove that their credentials satisfy verifiers' policies.

zkSSI includes three main components:

• Verifiation presentation generation: uses zk-snarks (i.e., Noir) to generate the presentation.
• Presentation verification: allows on-chain and off-chain verifiers to verify the presentation.
