Cryptographic Identity Solutions

• Keybase
  • dentropy (Paul Mullins) | Keybase
  • keybase device list
• PGP
  • Not allowed multiple keys, keys have expiry date, or they can sign a message saying they should not be used
• Matrix Protocol
  • Each device says it has a signing key, but all the rooms still have their own symmetric key
• Nostr DNS Identities
  • Link a cryptographic key to a DNS entry
• Mintter Identities
  • IDK what they are trying to actually do here, a single key per user I guess
• Technically ENS
  • Same as Nostr
