Main Business

• Problems with the iOS wrapper
  • Lohan: We are using CocoaPods to manage our dependencies within our iOS project. We are experiencing some issues with the pod "libindy-objc". 
  • Others with the same issue: https://forum.sovrin.org/t/ios-indy-sdk-image-not-found/1306
  • XCode 9 (what is currently supported by Indy SDK) is deprecated will soon be End-of-Life. Only supported in OSX before Sierra.
  • Previous experience with upgrading XCode: IS-1261
• Timeline for deprecating Indy wrappers in favor of Aries contributions
  • Focus is on the Aries SDK, no longer on the Indy SDK
  • Moving too fast to deprecate will scare people trying to get started today, because there are no mature alternatives in Aries today.
    • Especially with the mobile wrappers.
      • .NET and Xamarin is used by Open Source Mobile Agent (OSMA), which works today.
      • Team at DIDx is struggling with React Native. Wants to open source a React Native app platform.
      • WebAssembly would be the most performant approach.
    • BC.gov is working on a plan for building on existing Aries today.
• Evaluating Plenum
  • Pros versus other ledgers
  • Improvements we would like to make
  • Recent performance testing (increased batch size and write latency)
  • Top level Hyperledger Project?
• Problems with RBFT replicas:
  • Indy Node Epics
    • INDY-2251: Problems with RBFT Replicas
    • INDY-2250: Removing replicas (move from RBFT to Aardvark)

Future Calls

• Define the pull request review process for Indy Plenum/Node
  • Should define the process, including how we handle exceptions (emergency fixes shouldn't be blocked, but would require notification)
  • What is important in a good review?
    • Items from Evernym team:
      • covered by tests
      • has a link to the issue in Jira
      • fixed according to PoA
      • follows https://github.com/hyperledger/indy-node/blob/master/docs/source/write-code-guideline.md
  • Proposed Process (by Evernym team):
    • All Pull Requests can be reviewed by non-Evernym team members
    • Evernym team members will also do internal review in addition to external one
    • All interested parties are notified when a PR is sent
    • If a person wants to do an external review, he or she puts a comment or tag. This needs to be done in X hours.
    • Once a reviewer put a "want-to-review" tag, he or she need to finish review in Y hours
    • If no one wants to review a PR in X hours, or review is not finished in Y hours, we can do our internal review and merge the PR
    • An external review can be done against closed PRs as well, and Evernym team will process all findings ASAP
    • We may merge a PR with internal review only in case of urgency (critical fixes, release preparation etc.)
  • Items to be defined with the Community:
    1. A timeframe for external review (X):
       - X=12 hours, Y=2 days?
    2. What projects it should affect?
       - Plenum and Node?
       - Only Node?
       - We are not proposing SDK as it will be split to Aries in any case
    3. Who is going to commit to participate in this process?
• Migration of Indy-SDK to Aries-Core
• Requirements question: IS-1099, should we allow duplicate credentials from the same issuer?
• Non-secrets in the Indy Wallet
  • Cam is working on pluggable crypto. They wallet shouldn't decide what encryption you should be using.
  • Use cases where we would want to move keys between wallets
    • Moving the link secret / credential data from one device to another (synchronized storage).
    • Debug use cases
    • Richard's hit other uses cases that were better solved with DID Doc,  pre-signing, signing API.
