Corda: Transaction occurrence notification to a non-participant node -


is there way node can notified on occurrence of transaction between 2 different parties , not able view details of transaction? example, in simple trade finance use case, possible export bank know sales contract has been agreed upon between seller , buyer before approving letter of credit received import bank? assuming export bank not party sales contract transaction , hence not need sign it.

yes. flowlogic.send can send type of information, not transactions. part of flow, include call send sends message export bank.

the message normal string, or perhaps string signed both parties (to prove have indeed agreed transaction, , it's not buyer/seller lying export bank).
