What problem does it solve?

This Skill helps in selecting and understanding the cryptographic primitives for zero-knowledge verifiable credentials, guiding the trade-offs between different signature schemes, commitment schemes, and encoding methods.

Core Features & Use Cases

• Signature Scheme Trade-offs: Analyze the trade-offs between BBS+, SD-JWT-VC, and EdDSA for selective disclosure and in-circuit verification cost.
• Commitment Schemes: Evaluate Pedersen, Poseidon, Merkle trees, and KZG/IPA polynomial commitments for different use cases.
• Encoding RDF Triples: Learn how RDF triples are encoded into field elements for circuit-friendly representations.
• Public-input Contract: Understand the public-input contract between the credential layer and the Noir circuit.
• Use Case: When designing a system that uses verifiable credentials and needs to choose the right cryptographic primitives for security and efficiency.
