IRS Demo

This demo brings up three nodes: Bank A, Bank B and a node that simultaneously runs a notary, a network map and an interest rates oracle. The two banks agree on an interest rate swap, and then do regular fixings of the deal as the time on a simulated clock passes.

To run from the command line in Unix:

  1. Run ./gradlew samples:irs-demo:deployNodes to install configs and a command line tool under samples/irs-demo/build
  2. Run ./gradlew samples:irs-demo:installDist
  3. Move to the samples/irs-demo/build directory
  4. Run ./nodes/runnodes to open up three new terminals with the three nodes (you may have to install xterm)

To run from the command line in Windows:

  1. Run gradlew.bat samples:irs-demo:deployNodes to install configs and a command line tool under samples\irs-demo\build
  2. Run gradlew.bat samples:irs-demo:installDist
  3. Run cd samples\irs-demo\build to change current working directory
  4. Run nodes\runnodes to open up several 6 terminals, 2 for each node. First terminal is a web-server associated with every node and second one is Corda interactive shell for the node

This demo also has a web app. To use this, run nodes and then navigate to http://localhost:10007/web/irsdemo and http://localhost:10010/web/irsdemo to see each node's view of the ledger.

To use the web app, click the "Create Deal" button, fill in the form, then click the "Submit" button. You can then use the time controls at the top left of the home page to run the fixings. Click any individual trade in the blotter to view it.

Note: The IRS web UI currently has a bug when changing the clock time where it may show no numbers or apply fixings inconsistently. The issues will be addressed in a future milestone release. Meanwhile, you can take a look at a simpler oracle example here: https://github.com/corda/oracle-example.
