Idemix is a cryptographic protocol suite, which provides strong authentication as well as privacy-preserving features such as anonymity, the ability to transact without revealing the identity of the transactor, and unlinkability, the ability of a single identity to send multiple transactions without revealing that the transactions were sent by the same identity. More details here - https://hyperledger-fabric.readthedocs.io/en/release-2.2/idemix.html
Current JavaSDK doesnFabric Java SDK doesn't support storing Idemix credentials have support to store an Idemix Identities in Hyperledger Fabric Wallet. The objective of this mentorship program is to give support wallets to store idimix identitiesto store Idemix Identities in a Wallet.

- Discussion about Project Plan with Mentor and Defining the Timelines, Milestones and Deliverables
Run sample network and run Idemix example. | Done |
June 29 - July 12Ability to store Idemix Identity in a Wallet by using Fabric SDK for Java. | - Install Prerequisites and Bring up & play with the sample Fabric Network
- Setting Up and Configuring the network to fit for Idemix Usage
- Identification of Basic flow for using Identity Mixer in Fabric
| Done |
| July 13 - July 26 | Basic Flow Test of Idemix Usage in Fabric:
- Issuer - Fabric CA
- By default, Fabric CA is configured to issue Idemix Credentials
- Verifier - IdemixMSP in Channel Configuration
- Creating & Specifying Idemix MSP in "configtx.yaml"
- Generate Idemix Organization MSP Definition using "configtxgen" in form of JSON
- Updating Channel Configuration to update Idemix Organization MSP by Existing Organization Admin (with necessary approvals)
- User - From CLI (now) / Java SDK (later)
- Generate Idemix Credential for an User with Idemixgen Tool but with "Fabric CA Idemix Credentials"
- Export Necessary ENV Variables.
- Submit a Transaction to Network using an "idemix" User
