Bank Of Corda demo
This demo brings up three nodes: a notary, a node acting as the Bank of Corda that accepts requests for issuance of some asset and a node acting as Big Corporation which requests issuance of an asset (cash in this example).
Upon receipt of a request the Bank of Corda node self-issues the asset and then transfers ownership to the requester after successful notarisation and recording of the issue transaction on the ledger.
.. note:: The Bank of Corda is somewhat like a "Bitcoin faucet" that dispenses free bitcoins to developers for testing and experimentation purposes.
To run from the command line in Unix:
- Run
./gradlew samples:bank-of-corda-demo:deployNodesto create a set of configs and installs undersamples/bank-of-corda-demo/build/nodes - Run
./samples/bank-of-corda-demo/build/nodes/runnodesto open up three new terminal tabs/windows with the three nodes - Run
./gradlew samples:bank-of-corda-demo:runRPCCashIssueto trigger a cash issuance request - Run
./gradlew samples:bank-of-corda-demo:runWebCashIssueto trigger another cash issuance request. Now look at your terminal tab/window to see the output of the demo
To run from the command line in Windows:
- Run
gradlew samples:bank-of-corda-demo:deployNodesto create a set of configs and installs undersamples\bank-of-corda-demo\build\nodes - Run
samples\bank-of-corda-demo\build\nodes\runnodesto open up three new terminal tabs/windows with the three nodes - Run
gradlew samples:bank-of-corda-demo:runRPCCashIssueto trigger a cash issuance request - Run
gradlew samples:bank-of-corda-demo:runWebCashIssueto trigger another cash issuance request. Now look at the your terminal tab/window to see the output of the demo
To verify that the Bank of Corda node is alive and running, navigate to the following URL: http://localhost:10007/api/bank/date
In the window you run the command you should see (in case of Web, RPC is similar):
- Requesting Cash via Web ...
- Successfully processed Cash Issue request
If you want to see flow activity enter in node's shell flow watch. It will display all state machines running
currently on the node.
Launch the Explorer application to visualize the issuance and transfer of cash for each node:
``./gradlew tools:explorer:run`` (on Unix) or ``gradlew tools:explorer:run`` (on Windows)
Using the following login details:
- For the Bank of Corda node: localhost / port 10006 / username bankUser / password test
- For the Big Corporation node: localhost / port 10009 / username bigCorpUser / password test
See https://docs.corda.net/node-explorer.html for further details on usage.
