Trader demo
|
||||
-----------
|
||||
|
||||
This demo brings up three nodes: Bank A, Bank B and a notary/network map node that they both use. Bank A will
|
||||
be the buyer, and self-issues some cash in order to acquire the commercial paper from Bank B, the seller.
|
||||
|
||||
This can be run either from the command line (recommended for Mac/Linux/BSD users), or from inside IntelliJ.
|
||||
|
||||
To run from the command line:
|
||||
|
||||
1. Run ``./gradlew samples:trader-demo:deployNodes`` to create a set of configs and installs under ``samples/trader-demo/build/nodes``
|
||||
2. Run ``./samples/trader-demo/build/nodes/runnodes`` to open up three new terminal tabs/windows with the three nodes.
|
||||
3. Run ``./gradlew samples:trader-demo:runBuyer`` to set up the buyer node with some self-issued cash. This step
|
||||
is not expected to print much.
|
||||
4. Run ``./gradlew samples:trader-demo:runSeller`` to trigger the transaction. You can see both sides of the
|
||||
trade print their progress and final transaction state in the bank node tabs/windows.
|
||||
|
||||
To run from IntelliJ:
|
||||
|
||||
1. Open the Corda project in IntelliJ and run the "Install" configuration
|
||||
2. Open the Corda samples project in IntelliJ and run the "Trader Demo: Run Nodes" configuration
|
||||
3. Run "Trader Demo: Run Buyer"

# Trader Demo
|
||||
|
||||
Please see docs/build/html/running-the-demos.html
|
||||
This demo shows a couple of nodes doing an atomic asset swap: cash for commercial paper.
|
||||
|
||||
This program is a simple driver for exercising the two party trading protocol. Until Corda has a unified node server
|
||||
programs like this are required to wire up the pieces and run a demo scenario end to end.
|
||||
|
||||
If you are creating a new scenario, you can use this program as a template for creating your own driver. Make sure to
|
||||
copy/paste the right parts of the build.gradle file to make sure it gets a script to run it deposited in
|
||||
build/install/r3prototyping/bin
|
||||
|
||||
In this scenario, a buyer wants to purchase some commercial paper by swapping his cash for the CP. The seller learns
|
||||
that the buyer exists, and sends them a message to kick off the trade. The seller, having obtained his CP, then quits
|
||||
and the buyer goes back to waiting. The buyer will sell as much CP as he can!
|
||||
|
||||
The different roles in the scenario this program can adopt are:
|
||||
|
||||
This template contains the build system and an example application required to get started with [Corda](http://todo.todo).
|
||||
|
||||
## Prerequisites
|
||||
|
||||
You will need to have [JDK 8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
|
||||
installed and available on your path.
|
||||
|
||||
## Getting Started
|
||||
|
||||
First clone this repository and the Corda repository locally. Then open a terminal window in the Corda directory and run:
|
||||
|
||||
Unix:
|
||||
|
||||
./gradlew publishToMavenLocal
|
||||
|
||||
Windows:
|
||||
|
||||
gradle.bat publishToMavenLocal
|
||||
|
||||
This will publish a copy of Corda to your local Maven repository for your Cordapp to use. Next open a terminal window
|
||||
in your Cordapp directory (this one) and run:
|
||||
|
||||
Unix:
|
||||
|
||||
./gradlew deployNodes
|
||||
|
||||
Windows:
|
||||
|
||||
gradlew.bat deployNodes
|
||||
|
||||
This command will create several nodes in `build/nodes` that you can now run with:
|
||||
|
||||
Unix:
|
||||
|
||||
cd build/nodes
|
||||
./runnodes
|
||||
|
||||
Windows:
|
||||
|
||||
cd build/nodes
|
||||
ruunnodes.bat
|
||||
|
||||
This will now have nodes running on your machine running this Cordapp. You can now begin developing your Cordapp.
|
||||
|
||||
