Solution

Expand WAL-CLI implementation to create an API-based identity wallet service

Problem

WAL-CLI is a great tool, but it can be of greater utility for the developer community if it is expanded into an Identity wallet API service.

WAL-API Identity Wallet Service

Please describe your proposed solution.

The proposed solution is simple: a Swagger API implementation for the WAL-CLI project. Check the repository here. It includes wallet, DID, credential, and key management operations.

Please describe how your proposed solution will address the Challenge that you have submitted it in.

Several technical components must exist to foster a decentralized identity ecosystem for solutions to be realizable. IOG has done a great job providing Atala PRISM SDK and PRISM Nodes, but that is not enough. Some gaps must be covered before the community can build a DID ecosystem. The purpose of WAL-CLI is to work with RootsWallet and complete the missing parts we need to get the ecosystem going. We address the challenge by providing the open-source technology required to start building solutions.

What are the main risks that could prevent you from delivering the project successfully and please explain how you will mitigate each risk?

The team is comfortable in the technical position. The main concern lies in Atala PRISM SDK, which hasn't been fully released to the public and is under IOG private repositories. Atala PRISM Team has offered access to pioneer program Canvas Curriculum material to all proposers, so technically, this shouldn't be a problem because all potential users of the CLI tool are part of the Atala PRISM Pioneer Program.

Please provide a detailed plan, including timeline and key milestones for delivering your proposal.

Research (week 1): Tasks needed for stablishing the technology stack and draft the architecture.

Design (week 1-2): Refinement of the architecture definition and data modeling. The outcome of this phase is a defined architecture and design. List of identified endpoints is presented below:

  • Wallet API endpoints

  • new-wallet - Create a wallet

  • show-mnemonic - Show wallet mnemonic phrase and passphrase

  • export-wallet - Export a wallet

  • import-wallet - Import a wallet

  • list-wallets - List wallets

  • DID API endpoints

  • new-did - Create a DID

  • publish-did - Publish a DID

  • show-did-data - Show DID data

  • show-did - Show DID document

  • resolve-prism-did - Resolve PRISM did and show DID document

  • list-dids - List wallet DIDs

  • Credential API endpoints

  • issue-cred - Issue a credential

  • verify-cred - Verify a credential

  • export-cred - Export an issued credential

  • import-cred - Import a credential

  • revoke-cred - Revoke a credential

  • Key management API endpoints

  • add-key - Add a key to a DID

  • revoke-key - Revoke DID key

Implementation (week 3-4): Actual coding of all the elements defined above.

Testing (week 5):

  • Create unit tests for the main functions
  • Integration testing between WAL Instances
  • Integration testing between WAL Instance and RootsWallet

Documentation (week 5):

  • Setup instructions
  • Design and architecture diagrams
  • Tutorial

Please provide a detailed budget breakdown.

The budget is segmented according to the phases described previously at a ratio of $30/hr.

  • Research: 20hr = $600
  • Design: 30hr = $900
  • Implementation: 75hr = $2250
  • Testing : 25hr = $750
  • Documentation: 15hr = $450

Total: 330hr x $30 = $4950

Please provide details of the people who will work on the project.

  • Co-Submitted and received funding for the following proposals:
  • F8: WAL-CLI Communication (In progress 🚧)

If you are funded, will you return to Catalyst in a later round for further funding? Please explain why / why not.

Yes, the WAL-CLI Solution is divided into multiple phases of development. In each one, additional features are added. We will continue submitting proposals until all the parts are covered.

Please describe what you will measure to track your project's progress, and how will you measure these?

The team will manage the development in a public Github repository: <https://github.com/roots-id/wal-cli> so the community can audit and validate the work. Also, the community can ask about the project's progress here.

What does success for this project look like?

The success of this project will be determined by delivering a complete, tested, and documented open-source solution that covers the functionality presented in this proposal.

Please provide information on whether this proposal is a continuation of a previously funded project in Catalyst or an entirely new one.

The proposal is a continuation of WAL-CLI and WAL-CLI Communication
