• Header:
  • typ: jwt
  • alg: verification algorithm such as EdDSA
  • crv: curve name
  • kid: key id from previous DID that is used in the signature of this JWT
• Payload:
  • sub: the new DID
  • iss: the previous DID
  • iat: datetime in seconds
• Signature: from the previous DID and key defined in the kid

Extension Return Route Header

For HTTP transports, the presence of this message decorator indicates that the receiving agent MAY hold onto the connection and use it to return messages as designated. HTTP transports will only be able to receive at most one message at a time. Websocket transports are capable of receiving multiple messages over a single connection.
