quorum-network

This repository contains a simple setup for Quorum blockchain platform.

It is based on the 7nodes example and offers a simple setup of a Quorum network with or without the Tx Manager for Quorum's privacy features, and with these three supported consensus algorithms:

  • Raft
  • Clique
  • Istanbul

With this example one can start up a fully-functioning Quorum Ethereum private network consisting of 8 indipendent Quorum nodes. Each node runs in a single docker container abd exposes RPC APIs and a Geth console for testing different consensus, privacy, and all the expected functionality of an Ethereum platform. Additionally to its original version, this example enables the user to easily setup a quorum network running with the clique consensus protocol. By default the example runs also 7 Tx Manager nodes for privacy futures - the node 8 does not have this functionality. Tessera's privacy nodes can be easily disabled as shown below.

Run the example

  1. Make sure you have <docker-compose> installed. If not you can follow this to install Docker Compose,
  2. Download and run the example
git clone https://github.com/deanstef/quorum-network.git
cd quorum-network
docker-compose up -d
  1. By default this example runs a Quorum network with Tessera privacy managers and Istanbul BFT consensus. To use another consensus and disable the privacy manager, set the environment variables QUORUM_CONSENSUS=<raft|clique> PRIVATE_CONFIG=ignore
PRIVATE_CONFIG=ignore QUORUM_CONSENSUS=raft docker-compose up -d
  1. Run docker ps to show all the quorum containers (7 nodes and 7 tx managers)
  2. Run docker logs <container-name> -f to view the logs for a particular container or docker-compose logs -f to view all the logs
  3. Start interact with the network either by accessing the RPC APIs listed here or by accessing the geth Javascript console
  • curl example
$ curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_sendTransaction","params":[{"from": "0xed9d02e382b34818e88b88a309c7fe71e65f419d","to": "0xca843569e3427144cead5e4d5999a3d0ccf92b8e","value": "0x1"}],"id":1}' http://localhost:22000

{"jsonrpc":"2.0","id":1,"result":"0xb94fa38850b30f891c95f944c9649426984517d7783c00a75cd0da71d7cf7f7b"}
  • Access Javascript console
$ docker exec -it <container-name> geth attach /qdata/dd/geth.ipc
Welcome to the Geth JavaScript console!

  1. Shutdown Quorum Network
docker-compose down
  1. Remove all the volumes with the chain data. note: This command will delete all the Docker volumes on your machine
docker volume prune -f
