  • Indy-VDR
  • "State proof" validation bug reported through the HTTP Proxy: audit ledger proof

        • Foundation's GitLab environment isn't functional
        • Hyperledger is using Azure Pipelines, but concerns about running an Indy Pool there
        • Evernym team's recent research:
          • Unable to render Jira issues macro, execution error.  GitLab
          • Unable to render Jira issues macro, execution error. GitHub Actions

    • Need to evolve DIF DIDComm to support Rich Schemas
    • Implement first in Indy-VDR and Indy-Credx, then decide how to migrate there from LibIndy.
    • How will we mix old credential definitions with new credential definitions?
      • Only difference is the mapping object
