Agenda

• Record the meeting
• DIDComm V2
  • HackMD: https://hackmd.io/8QhG-zekRbaliJYDs6Y7-Q 
  • Ursa also has crypto, but not for DIDComm we think?
    • https://github.com/hyperledger/ursa
  • Multiple approaches
    • Custom implemnation with lower level crypto (e.g. Askar)
      • lower level, more effort
      • https://github.com/hyperledger/aries-askar
      • https://github.com/hyperledger/aries-cloudagent-python/blob/main/aries_cloudagent/askar/didcomm/v2.py
      • Askar has storage and crypto in one, while for a modular approach we want it separated
        • Already separated in AFJ through interface
        • In browser you don't need a native backend / advanced storage, but you do need the crypto
    • DIDComm library from SICPA (WASM)
      • WASM Support in react native is not great
      • React Native wrapper available, but only for Android: https://github.com/sicpa-dlab/didcomm-react-native/tree/main/android/src/main/java/com/sicpa/didcomm/reactnative
      • Could look at JSI interface wrapper like https://github.com/animo/react-native-bbs-signatures
      • DIDComm v2 branch in AFJ: https://github.com/sicpa-dlab/aries-framework-javascript/tree/didcomv2-contribution
      • Use our own did resolver, need also our own secret resolver.
    • DIDComm library in typescript
      • https://github.com/aviarytech/didcomm
• storage/data layer being abstracted into a well defined interface akin to what schema inversion technologies like PostgREST/Hasura end up providing
  • Wallet storage which takes advantage of Row Level Security would provide a long term option for the end user to be able to access their wallet while still enabling custodian ownership of their wallet by a identity service provider
  • Good discussion by Daniel Hardman about separation of Encryption and storage for wallets (starting from 49minutes)
• 0.3.0 release
• Docker container / image environments
