Project TitleExtend the secure DID Registry to on-board members of the organization on Github/Gitlab and enable functions to manage the Repo




A DID registry is a type of verifiable data registry that can be simply referred to as a role, a system performs to mediate the functionalities like create, verify, update, and deactivate the decentralized identifiers. This is the extension of the in-progress work handled during the last summer (can be accessed here). The project aims to automate the process of creating a secure DID Registry on Github/Gitlab, facilitating easy on-boarding of new organizations and enabling easy management. Decentralized ID (DIDtokens or we can call cryptographically-generated proofs of the organizations can be stored in the verifiable credential registries in an encrypted fashion to achieve the secure DID registry with zero infrastructure cost. The shell script is used to create the initial codebase. This project expects a mentee who is self-motivated and has a lot of passion for cryptography, decentralized identity, and open source.

The significant aspects to be considered here are Creation, Onboarding(Enable/Restrict Access), and Management(add/update/revoke).

a) Creation (of DIDRegistry): Function to create a DIDRegistry for an organization on Github. GitHub Organization can have multiple repositories, same is the case with DID Registries.

b) Onboarding: Function to add enable/restrict access to members of an organization to a repository (GitHub repo users can be made members of an Organization, with different roles and privileges).

c) Manage: Function to list APIs that are needed to add/update/revoke access DID’s or (DID Documents) saved as files on the repo.

Additional Information

You can learn about the project by accessing drman repo. The issues to be focused on are listed under the issues tab here.

  1. DRman Registry scripts (DRM scripts )

  2. Github based VCR (Verifiable Credential Registry)

  3. Create and manage Aries VCR using DRman Registry Script

  4. Create and manage Aries-VCGR ( Aries Verifiable Credential Github Registry ) using DRman Registry Scripts. While progressing, this can be done after along with the Design of Github based VCR (As mentioned in point 2)

Learning Objectives

The mentee will have an opportunity to learn

Expected Outcome

Relation to Hyperledger 

Github/Gitlab based DID registries  that can be used by Hyperledger Ursa, Hyperledger Aries, or any other Hyperledger Framework that needs to interact with DID Registries 

Education Level

Graduate or Masters students preferred. Please do take a look at the skills.


Exposure to Hyperledger Ursa, hands-on with shell scripting, knowledge of Git, GitHub, or Gitlab is expected. Any high-level understanding of Decentralized Identity is also desirable to some extent.

Future plans

The plan is to further enhance this as an open-source utility and add more capabilities required to manage a full-featured DID Registry on Github. 

Preferred Hours and Length of Internship

Part-time (20 hours a week for 24 weeks starting in summer and ending in fall)
