Online Discussion (from RocketChat this week)

• What is in a NYM state proof and if it can be "easily" extended

This Week's Discussion:

• From last week's discussion – confirmation of approach:
  • Update the NYM to add a "diddocContent" item that is the equivalent of what we proposed would go in the DIDDoc ATTRIB, with assembly left to the client 
    • Include support for the version_id and version_time resolution parameters.
    • Confirm error checking done on the NYM write.  See proposal in the hackmd document (valid JSON, no NYM fields, valid DIDDoc)
  • Other options rejected
    • Have a single call that gets the NYM and ATTRIB and state proofs for both with same multi-signed merkle root, and leave the assembly to the client.
      • Likely choice if extending the NYM is impractical
    • Do nothing
    • Single call with both state proofs and ledger does assembly
    • Write DIDDoc on ledger writes and have state proof for DIDDoc
    • Add WRITE_DIDDOC transaction 
• Decision on assembly points of concern:
  • The "nymKeyAgreement" flag
  • Remove the "content" item and just inline the rest of the ATTRIB?
• Other Indy Ledger Objects as DIDs (e.g. schema, etc):
  • Drummonds proposal: https://docs.google.com/document/d/1f99z4Bf8F-DA8EbkNjInVQv2ncJGPwF_Dp7I7Mfyhqs/edit
  • Existing transactions

Future Discussions:

• What format for other objects on the ledger as DIDDocs.
• Handling existing objects on the ledger as DIDDocs?
• DNR and DND discussions
  • To find networks we will require at least the first and perhaps the second of these approaches, while the rest are suggested:
    • Config files for one or more known networks
    • A mechanism for a ledger operator to register discovery information for other ledgers (aka "human gossip")
      • A DID/DIDDoc on a ledger will contain cross-registry information
      • A mechanism is needed for finding the DID(s) that contain the registrations – ideas have been put forward - a DID Name Directory (DND) is the likely approach.
      • Document about the DND and DNR records
    • Decentralized registries based on verifiable credentials
    • Other registry mechanisms, such as the DDNR proposal
    • The DID Method Spec will include a reference to a repo (likely) "indy-did-networks" within Hyperledger that will be a lightly managed, structured repository of folders per Indy network with at least the config file(s) for the networks. Use of the repo is voluntary, but provides a convenient way for networks to publish information about the network. Maintainers will be selected from the community and should exhibit a light hand in accepting PRs, being concerned mainly with structure of the data (not content) and that contributors are not being malicious about updating the information of other network operators. The Hyperledger governance structure may be used for disputes as appropriate. This is not a replacement for the Governance that a specific network should implement.
