Environment setting

Steps to set up blockchain environment.

• ref: Quorum from Scratch
• Or using Quorum-wizard to quickly start 7-node blockchain for testing.

Using Ganache

1. Create virtualenv and install library

   virtualenv -p ~/.pyenv/versions/3.8.5/bin/python venv
   pip install --upgrade web3
   pip install flask

   Or you can just run installLib.sh to install all library you need.

2. Change your node.js version to 12 (Version 14 has some issue to start ganache-cli, is still not fixed.)

   nvm use 12

3. Start ganache-cil

   ganache-cli -p 7545 -q

4. Download solc to compile solidity file in local.

   sudo add-apt-repository ppa:ethereum/ethereum
   sudo apt-get update
   sudo apt-get install solc

Build Quorum locally

1. Run add_node_raft.py: Will clone the Quorum repo, build, and add 13 nodes on local.
2. Go to your cloned quorum/fromscratch file and run geth by ./startnode.sh to start all nodes.
3. Run addPeer.py file to add other peers automatically into quorum network through command line.

And DONE!
