• Problems with RBFT replicas:
  • Indy Node Epics
    • INDY-2251: Problems with RBFT Replicas
    • INDY-2250: Removing replicas (move from RBFT to Aardvark)
  • Ken's summary:
    A simplification to our current algorithm to reduce complexity and simplify the method for determining when to perform a view change making our system more resistant to attack. It takes full advantage of our recent PBFT view change and monitoring logic improvements while boosting performance of the system. The cost and risk to make these changes is low.
• Recent performance tests:
  • Indy-2262: performance problems (BLS signature?), and batch size (3 second write latency, INDY-2277)
  • Widget Connectorurlhttps://www.youtube.com/watch?v=OSpssHQXlOI&list=PLRp0viTDxBWGLdZk0aamtahB9cpJGV7ZF
• Bug with Audit ledger history:
  • https://sovrin.atlassian.net/browse/SN-8
• Evaluating Plenum
  • Pros versus other ledgers
  • Improvements we would like to make
  • Recent performance testing (increased batch size and write latency)
    • Other ledgers worry less about delays in confirmation for transaction writes to achieve higher scalability.
  • Top level Hyperledger Project?
  • Evaluating alternatives like Tendermint and Libra HotStuff
  • How can we recruit contributors from the Sovrin Steward community?
• 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.
      • Problems with iOS and XCode:

    • BC.gov is working on a plan for building on existing Aries today.
