Enhanced-privacy DID and Efficient Zero-knowledge Proof Comparison and Implementation in Hyperledger (CL-Signature and ZK-SNARKs) - Gyeongjin Ra, & Taehoon Kim, Soonchunhyang University

The capacity for users to monitor the custody of their own identifiers and credentials and novel data ownership and governance identity management(IDM) models with built-in control and consent mechanisms can be supported by blockchain technology. In particular, proof of zero-knowledge proof (ZKP) allows for efficient data verification and selective disclosure without exposing it. ZK SNAKRs was applied to cryptocurrency Z-Cash, CL-Signature has been applied to the Hyperledger Fabric INDY project and various DIDs. Our contribution is we modify and implement the ZK-SNAKRs scheme used in Z-Cash for the Hypberledger Fabric. Then, We design and develop the Enhanced-Privacy IDM Framework using the pre-mentioned ZKP. We have implemented and validated ZK-SNAKRs being more efficient in proof verification than CL-Signature in the same environment called Hyperledger.
