Hyperledger AnonCreds v2 ZKP-based Credential Revocation Manager Implementation
About the Organization
Hyperledger AnonCreds v2 takes the privacy-preserving features of AnonCreds v1 Verifiable Credentials to a new level. AnonCreds v2 adds support for newer, mature cryptosuites (including BBS+ Signatures), and for a number of important Zero Knowledge Proofs (ZKP) that enable an even better balance between verifiability and privacy. AnonCreds v2 also adds a crucial new, highly-scaled approach to ZKP-based credential revocation – a crucial element of almost all verifiable credential ecosystems. Called ALLOSAUR, this new scheme allows a single revocation registry to be created by an verifiable credential issuer that scales to support millions of credentials in a fast, low-data manner. Instead of sharing millions of credential revocation statuses (revoked or not), the scheme relies on the transfer of just a handful of integers between participants, enabling secure revocation without a verifiable credential holder from having to share a correlatable identifer for themself to the verifier. ALLOSAUR requires the creation of a new component in the verifiable credential ecosystem, the revocation manager, which is the goal of this Hyperledger Mentorship – to implement a scalable ALLOSAUR revocation manager. The implementation will at least be partially in Rust, with flexibility on the choice of languages/frameworks for the web service.
