corda/samples/network-visualiser

Network Visualiser

This package contains a network visualiser that uses a simulation to visualise the interaction and messages between nodes on the Corda network.

Prerequisites

You will need to have JDK 8 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:

Windows users currently have to manually enter each directory in build/nodes and run java -jar corda.jar in each. This will be updated soon.

This will now have nodes running on your machine running this Cordapp. You can now begin developing your Cordapp.
