Trader demo
|
|
-----------
|
|
|
|
This demo brings up five nodes: Bank A, Bank B, Bank Of Corda, NonLogging Bank and a notary node that they all use. Bank A
|
|
will be the buyer, and requests some cash from the Bank of Corda in order to acquire commercial paper from Bank B, the
|
|
seller.
|
|
|
|
The NonLogging Bank node is present to demonstrate the usage of the "Configuring Responder Flows" feature of Corda described [here](https://docs.corda.net/head/flow-overriding.html).
|
|
The override is defined within the deployNodes section of the `build.gradle`. In this case, we are overriding the default responder for `net.corda.traderdemo.flow.SellerFlow`
|
|
to be a version that does not print out information about the transaction.
|
|
|
|
```groovy
|
|
node {
|
|
name "O=NonLogging Bank,L=London,C=GB"
|
|
p2pPort 10025
|
|
rpcUsers = ext.rpcUsers
|
|
rpcSettings {
|
|
address "localhost:10026"
|
|
adminAddress "localhost:10027"
|
|
}
|
|
extraConfig = ['h2Settings.address' : 'localhost:10035']
|
|
flowOverride("net.corda.traderdemo.flow.SellerFlow", "net.corda.traderdemo.flow.BuyerFlow")
|
|
}
|
|
```
|
|
|
|
To run from the command line in Unix:
|
|
|
|
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 five new terminals with the five nodes
|
|
3. Run ``./gradlew samples:trader-demo:runBank`` to instruct the bank node to issue cash and commercial paper to the
|
|
buyer and seller nodes respectively
|
|
4. Run ``./gradlew samples:trader-demo:runSeller`` to trigger the transaction. If you entered ``flow watch``, you can
|
|
see flows running on both sides of transaction. Additionally you should see final trade information displayed to
|
|
your terminal
|
|
|
|
To run from the command line in Windows:
|
|
|
|
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 five new terminals with the five nodes
|
|
3. Run ``gradlew samples:trader-demo:runBank`` to instruct the buyer node to request issuance of some cash from the
|
|
Bank of Corda node
|
|
4. Run ``gradlew samples:trader-demo:runSeller`` to trigger the transaction. If you entered ``flow watch``, you can see
|
|
flows running on both sides of transaction. Additionally you should see final trade information displayed to your
|
|
