// An example on how to generate a local SSL certificate in Go
// and serve HTTPS traffic with it.
//
// Code taken from the book Go Web Programming by Sau Sheong Chang
// https://github.com/sausheong/gwp
//
// Run with `--https` to serve traffic via HTTPS (it will create the certificate
//	and private key files if they don't exist)
//
// Run with no parameters to serve traffic via HTTP (no certificates needed)

Create your own Ethereum testnet

Introduction

We will be using 3 virtual machines as 3 Ethereum node. We used 'Ubuntu Server 14.04 LTS trusty', and 'Ubuntu 15.10 wily' for this experiment. Root Ethereum node will be referred as 'root node', client nodes will be referred as 'client node A' & 'client node B' respectively. On root node port 30303 must be accessible from outside.

Installation

Below are the installation instructions for the latest versions of Ubuntu. This step must be executed and Ethereum go client 'geth' must be installed on every node.
