Working Together to Build an Aries Application for Sovrin

Session given as part of the Identity workshop at the Hyperledger Boot Camp Moscow 2019.

Attendees wanted to have a hand-on session to get started building an identity application. This brief slide deck provided a framework for that session. Providing detailed guidance on building an identity application is currently hard to do, because the components are evolving rapidly.

2. It’s early days Tools are changing quickly Documentation isn’t very polished We’ll work together, and get unstuck together Disclaimers
3. Protocol Ecosystem: Aries Features: ZKPs Network: Sovrin Language: Python Issuer Software: ACA-Py Make Your Choices
4. Sovrin Verifiable Credentials Ecosystem
5. Relevant Projects
6. Setup Indy Install Indy CLI (Debian) (https://github.com/hyperledger/indy-sdk/blob/master/README.md) Install the genesis files for Sovrin Builder Net (https://forum.sovrin.org/t/how-to-access-the-public-sovrin-network/1035) Generate a DID Anchor the DID as an issuer (https://selfserve.sovrin.org)

8. Setup ACA-Py Install ACA-Py (Docker) Get it to use your issuer DID? Code the controller
9. Design a Credential Decide on your use case Select your attributes Define your Schema Define your Cred (Future: define your presentation)
10. Components of a Credential Credential Definition Verifiable Credential 1 Presentation Presentation Definition Verifiable Credential n Mapping Schema Encoding Schema Schema Presentation Definition
11. Test Issue a credential Verify the credential
12. Setup Governance Who is going to issue the credential? Why will the verifier trust the credential?
