Connecting Quorum 7 Node to Epirus

As we start off exploring more into the realms of blockchain, we need to understand that most on-chain development or deployment uses the terminal for the UI.

That means ingesting a lot of information via the terminal. We live in the post-modern dial-up, the least we can do is provide some good visuals to make sense of all the data.

In the Summer of June 2017, JP Morgan launched a fork of Ethereum called, Quorum.

“Based on Ethereum, Quorum is an open source blockchain platform that combines the innovation of the public Ethereum community with enhancements to support enterprise needs.

We are going to deploy a UI that will allow us to see the interactions on/off-chain.

Well a quick Wikipedia search says,

“Epirus, is a traditional geographic and modern administrative region in northwestern Greece.”

For this example the best way to remember it is think of it as the bridge to you and your blockchain data, contract creation, and asset tracking.

Let’s get the basics to run this on our computers.

4. To shutdown the Vagrant instance, run vagrant suspend. To delete it, run vagrant destroy. To start from scratch, run vagrant up after destroying the instance.

Get Quorum 7 node example

You need to make some minor changes to the docker-compose.yml file so that epirus can connect a running node.

Change the networks name property from epirus-net to quorum-examples-net in the networks settings:

sed -i 's/name: epirus-net/name: quorum-examples-net/g' docker-compose.yml

The networks property should now looks like this:

Now you can start epirus with the following command.

You should see the following happening in the terminal window. This means that everything has started successfully.

This may to several minutes for Epirus to be displayed, (MacBook Pro ~ 20+ minutes).

This should now show up in your browser when you go to localhost;if you click on blocks you will see this same UI.

To close Epirus or Quorum you can execute the following line in your terminal:

docker-compose down
