FinalityHandler is insecure in that it is open to receive any transaction from any party. Any CorDapp targeting platform version 4 or above is required use the new c'tors which take in FlowSession objects to the counterpart flow. This flow must subcall ReceiveFinalityFlow to receive and record the finalised transaction. Old CorDapps (with target platform version < 4) will continue to work as previously. However if there are no old CorDapps loaded then the node will disable FinalityHandler.
Attachment Demo
This demo brings up three nodes, and sends a transaction containing an attachment from one to the other.
To run from the command line in Unix:
- Run
./gradlew samples:attachment-demo:deployNodes
to create a set of configs and installs undersamples/attachment-demo/build/nodes
- Run
./samples/attachment-demo/build/nodes/runnodes
to open up three new terminal tabs/windows with the three nodes and webserver for BankB - Run
./gradlew samples:attachment-demo:runRecipient
, which will block waiting for a trade to start - Run
./gradlew samples:attachment-demo:runSender
in another terminal window to send the attachment. Now look at the other windows to see the output of the demo
