anoncreds-rs

Rust library and reference implementation of the Anoncreds V1.0 specification.

The AnonCreds (Anonymous Credentials) specification is based on the open source verifiable credential implementation of AnonCreds that has been in use since 2017, initially as part of the Hyperledger Indy open source project and now in the Hyperledger AnonCreds project. The extensive use of AnonCreds around the world has made it a de facto standard for ZKP-based verifiable credentials, and this specification is the formalization of that implementation.

Library

Anoncreds-rs exposes three main parts: issuer, prover and verifier.

Issuer

• Create a schema
• Create a credential definition
• Create a revocation registry definition
• Create a revocation status list
• Update a revocation status list
• Update a revocation status list's timestamp
• Create a credential offer
• Create a credential

Prover / Holder

• Create a credential request
• Process an incoming credential
• Create a presentation
• Create, and update, a revocation state
• Create, and update, a revocation state with a witness

Verifier

• Verify a presentation
• generate a nonce

Wrappers

Anoncreds is, soon, available as a standalone library in Rust, but also via wrappers.

Credit

The initial implementation of anoncreds-rs is derived from indy-shared-rs that was developed by the Verifiable Organizations Network (VON) team based at the Province of British Columbia, and derives largely from the implementations within Hyperledger Indy-SDK.
