Extending HL Fabric for connecting with HL Indy






Hyperledger project provides an umbrella for several open-source distributed ledger frameworks, designed for both specific and generic purposes. Hyperledger Fabric is a modular and extendable code-base for building distributed ledgers in diverse fields ranging from medical research to banking and supply chain. On the other hand, Hyperledger Indy is a purpose-built distributed ledger for decentralized identity.

At the moment Hyperledger Fabric incorporates its own Membership Service for assigning digital identities to individuals and devices as well as for defining their roles and privileges in the network.  In the context of this project we will design and develop a custom Membership Service Provider (MSP) in Fabric for managing digital identities using a decentralized identity management system (Indy). The custom MSP will be the interface between Fabric and Indy and will translate requests and responses coming from Indy to Fabric and vice-versa.

Learning Objectives

-          Introduction to open-source culture and collaboration tools by contributing and collaborating in an open-source project

-          Understand both Fabric and Indy frameworks and meet the Hyperledger community

-          Learn to work with GitHub in an active project

-          Gain knowledge in distributed ledgers and blockchain

Expected Outcome

-          Study of the requirements (Report)

Relation to Hyperledger 

Hyperledger Fabric and Hyperledger Indy

Education Level

Graduate student or undergraduate student.


Languages: Go, Python

Blockchain platforms: Hyperledger Fabric (basic), Hyperledger Indy (basic)

Some cryptography knowledge (PKI) will be desirable.

Future plans

The project will be part of a larger open-source project for managing digital identities in off-grid communication networks, leveraging Hyperledger and other decentralized technologies.

Mentor(s) Names and Contact Info

Leandros Tassiulas,


  1. Hi - 
    Just want to check , if we can take this project into consideration for 2020?. 


    1. Lokesh waran thanks for the follow-up. We will be finalizing the approval of projects by mid this week and notify all who submitted the project proposals. 

  2. Min Yu  Thanks, actually this project submitted in 2019 by Leandros Tassiulas,

      but not chosen by any mentee. This project seems interesting to me, Lokesh waran and other community so can we consider this project /moved this project under 2020 projects so mentee can have option to select this too. 

  3. Kamlesh Nagware unfortunately this is not submitted to 2020 program for consideration. So we will not be able to include this project for this year. Thanks!
