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?
    • 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.
    • Work-around with the web-crypto API

Action items

  • HIPE #138, Issue #144 (Ken and Brent)
    • Create a PR for changing status to ACCEPTED
