Whistleblower -- Confidential Identity

This CorDapp is a simple showcase of confidential identities (i.e. anonymous public keys).

Concepts

A node (the whistle-blower) can whistle-blow on a company to another node (the investigator). Both the whistle-blower and the investigator generate anonymous public keys for this transaction, meaning that any third-parties who manage to get a hold of the state cannot identity the whistle-blower or investigator. This process is handled automatically by the SwapIdentitiesFlow.

Usage

Pre-Requisites

For development environment setup, please refer to: Setup Guide.

Running the CorDapp

Open a terminal and go to the project root directory and type: (to deploy the nodes using bootstrapper)

./gradlew clean build deployNodes

Then type: (to run the nodes)

./build/nodes/runnodes

Interacting with the nodes:

We will interact with this CorDapp via the nodes' interactive shells.

First, go the shell of BraveEmployee, and report BadCompany to the TradeBody by running:

flow start BlowWhistleFlow badCompany: BadCompany, investigator: TradeBody

To see the whistleblower case stored on the whistleblower node, run:

run vaultQuery contractStateType: net.corda.samples.whistleblower.states.BlowWhistleState

You should see something similar to the following output:

[ {
  "badCompany" : "C=KE,L=Eldoret,O=BadCompany",
  "whistleBlower" : "8Kqd4oWdx4KQGHGKubAvzAFiUG2JjhHxM2chUs4BTHHNHnUCgf6ngCAjmCu",
  "investigator" : "8Kqd4oWdx4KQGHGGdcHPVdafymUrBvXo6KimREJhttHNhY3JVBKgTCKod1X",
  "linearId" : {
    "externalId" : null,
    "id" : "5ea06290-2dfa-4e0e-8493-a43db61404a0"
  },
  "participants" : [ "8Kqd4oWdx4KQGHGKubAvzAFiUG2JjhHxM2chUs4BTHHNHnUCgf6ngCAjmCu", "8Kqd4oWdx4KQGHGGdcHPVdafymUrBvXo6KimREJhttHNhY3JVBKgTCKod1X" ]
} ]

We can also see the whistleblower case stored on the investigator node.
