# Node Explorer

The node explorer provide views to the node’s vault and transaction data using Corda’s RPC framework. The user can execute cash transaction commands to issue and move cash to other party on the network or exit cash using the user interface.

## Running the UI

Windows:

    gradlew.bat tools:explorer:run

Other:

    ./gradlew tools:explorer:run

## Running demo nodes

Windows:

    gradlew.bat tools:explorer:runDemoNodes

Other:

    ./gradlew tools:explorer:runDemoNodes

Note

3 Corda nodes will be created on the following port on localhost by default.

- Notary -> 20002
- Alice -> 20004
- Bob -> 20006

## Interface

Login
  User can login to any Corda node using the explorer. Alternatively, `gradlew explorer:runDemoNodes` can be used to start up demo nodes for testing. Corda node address, username and password are required for login, the address is defaulted to localhost:0 if leave blank. Username and password can be configured via the `rpcUsers` field in node’s configuration file; for demo nodes, it is defaulted to `user1` and `test`.

Note

If you are connecting to the demo nodes, only Alice and Bob (20004, 20006) are accessible using user1 credential, you won’t be able to connect to the notary.

Dashboard
  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 CordApp’s and provide useful information to system admin at a glance.

Cash
  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.

New cash transaction
  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. The result of the transaction will be visible in the transaction screen when executed.

Transactions
  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.

Network
  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 a intuitive way of visualizing the Corda network and the participants.

Settings
  User can configure the client preference in this view.

Note

Although the reporting currency is configurable, FX conversion won’t be applied to the values as we don’t have an FX service yet.
