# 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/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. Run ``./web/build/webapps/runwebapps`` to open three more terminals for associated webserver
|
|
|
|
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`` to open up several 3 terminals for each nodes
|
|
5. Run ``web\build\webapps\webapps`` 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. |
