The tool is distributed in the form of runnable JAR file: “corda-tools-explorer-4.3.jar”.
Running the UI
java -jar corda-tools-explorer-4.3.jar
cordappsdirectory located within the directory from which the node explorer is run.
Running demo nodes
Node Explorer is included with the DemoBench application, which allows you to create local Corda networks on your desktop. For example:
- Bank of Breakfast Tea (Issuer node for GBP)
- Bank of Big Apples (Issuer node for USD)
- Alice (Participant node, for user Alice)
- Bob (Participant node, for user Bob)
DemoBench will deploy all nodes with Corda’s Finance CorDapp automatically, and allow you to launch an instance of Node Explorer for each. You will also be logged into the Node Explorer automatically.
When connected to an Issuer node, a user can execute cash transaction commands to issue and move cash to itself or other parties on the network or to exit cash (for itself only).
When connected to a Participant node a user can only execute cash transaction commands to move cash to other parties on the network.
User can login to any Corda node using the explorer.
Corda node address, username and password are required for login, the address is defaulted to localhost:0 if left blank.
Username and password can be configured via the
rpcUsers field in node’s configuration file.
The dashboard shows the top level state of node and vault.
Currently, it shows your cash balance and the numbers of transaction executed.
The dashboard is intended to house widgets from different CordApps and provide useful information to system admin at a glance.
The cash view shows all currencies you currently own in a tree table format, it is grouped by issuer -> currency.
Individual cash transactions can be viewed by clicking on the table row. The user can also use the search field to narrow down the scope.
This is where you can create new cash transactions.
The user can choose from three transaction types (issue, pay and exit) and any party visible on the network.General nodes can only execute pay commands to any other party on the network.
Issuer nodes can execute issue (to itself or to any other party), pay and exit transactions.
The result of the transaction will be visible in the transaction screen when executed.
The transaction view contains all transactions handled by the node in a table view. It shows basic information on the table e.g. Transaction ID,
command type, USD equivalence value etc. User can expand the row by double clicking to view the inputs,
outputs and the signatures details for that transaction.
The network view shows the network information on the world map. Currently only the user’s node is rendered on the map.
This will be extended to other peers in a future release.
The map provides an intuitive way of visualizing the Corda network and the participants.
User can configure the client preference in this view.
