Previous Discussion:

  • The specific will be specific that all DIDs MUST be self-certifying – e.g. derived from the initial public key used in the NYM
  • We'll use ":" for subsidiary ledgers, and we'll include placehold support for KERI, leading to 4 cases:
    • Ledger with no subsidiary name, example: did:indy:sovrin:12345
    • KERI identifier on a ledger with no subsidiary name, example: did:indy:sovrin:keri:12345
    • Ledger with no subsidiary name, example: did:indy:sovrin:staging:keri:12345
    • KERI identifier on a ledger with a subsidiary name, example: did:indy:sovrin:staging:keri:12345
  • 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")
    • Decentralized registries based on verifiable credentials
    • Other registry mechanisms, such as the DDNR proposal

Online Discussion (from RocketChat this week)


Discussion:

  • Discussion led by Daniel Hardman about how to implement the gossiping mechanism via "networks" ledger DIDs - presentation
  • How to find previous versions of DIDs and what are the implementation ramifications of that?
