Environment setting

Steps to set up blockchain environment.

ref: Quorum from Scratch

Or using Quorum-wizard to quickly start 7-node blockchain for testing.

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.
Change your node.js version to 12 (Version 14 has some issue to start ganache-cli, is still not fixed.)
```
nvm use 12
```
Start ganache-cil
```
ganache-cli -p 7545 -q
```

Download solc to compile solidity file in local.

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

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

And DONE!
