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.

Functionality is split into two parts - CordApp which provides actual distributed ledger backend and Spring Boot webapp which provides REST API and web frontend. Application communicate using Corda RPC protocol.

To run from the command line in Unix:

  1. Run ./gradlew samples:irs-demo:cordapp:deployNodes to install configs and a command line tool under samples/irs-demo/cordapp/build
  2. Run ./gradlew samples:irs-demo:web:deployWebapps to install configs and tools for running webservers
  3. Move to the samples/irs-demo/ directory
  4. Run ./cordapp/build/nodes/runnodes to open up three new terminals with the three nodes (you may have to install xterm)
  5. On Linux, run ./web/build/webapps/runwebapps to open three more terminals for associated webservers. On macOS, use the following command instead: osascript ./web/build/webapps/runwebapps.scpt

To run from the command line in Windows:

  1. Run gradlew.bat samples:irs-demo:cordapp:deployNodes to install configs and a command line tool under samples\irs-demo\build
  2. Run gradlew.bat samples:irs-demo:web:deployWebapps to install configs and tools for running webservers
  3. Run cd samples\irs-demo to change current working directory
  4. Run cordapp\build\nodes\runnodes.bat to open up several 3 terminals for each nodes
  5. Run web\build\webapps\webapps.bat to open up several 3 terminals for each nodes' webservers

This demo also has a web app. To use this, run nodes and then navigate to http://localhost:10007/ and http://localhost:10010/ 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.
