Setting up NKN on DigitalOcean

NKN is the next generation of peer to peer network infrastructure built upon blockchain technology backed by Cellular Automata theory aiming at revolutionizing the Internet with true decentralization and native token incentive mechanism.

What is needed

SSH Terminal

• Windows: Recommend Putty, https://www.putty.org/
• Mac OS: Using default terminal

Getting Started

Login

If you already have DigitalOcean account, you can login into your account.

Sign up

If you don't have DigitalOcean account, please sign up.

1. Create Project

2. Create Droplets

Droplets configuration

• Choose an image

  • Debian: 9.5 x 64

• Choose a size

  • CPU: 1 GB
  • SSD: 25 GB
  • Transfer: 1000 GB
  • Price: $5 / month

• CPU Optimized Droplets (Skip)
• Add backups (Skip)
• Add block storage (Skip)
• Choose a datacenter region
  • Bangalore

• Select additional options (Skip)

• Add your SSH keys (Skip)

• Finalize and create

  • Choose a hostname: Type a name you'd like or using default

• Click Create

3. Connect to node

After create the Droplets, you will receive the email include:

• Droplet Name
• IP Address
• Username
• Password

Using terminal/putty to connect the droplet node

$ ssh root@<IP_ADDRESS>

NOTE: You must change your password at the first time you connect to the droplet node.

4. Installation

Update Debian

apt-get update

Use the latest version

apt-get upgrade

If you are asked what you want to do with it just stick with "keep the local version currently installed"

Install dependencies

apt-get install -y make curl git

Look up the goland latest version of go and store the download path in "url":

url=`curl https://golang.org/dl/ | grep linux-amd64 | sort --version-sort | tail -1 | grep -o -E "https://dl.google.com/go/go[0-9]+\.[0-9]+((\.[0-9]+)?).linux-amd64.tar.gz"`

Download the file

wget ${url}

Unzip the file

sudo tar -C /usr/local -xvf `echo ${url} | cut -d '/' -f5`

Finally set environment variables correctly: Please enter line by line with pressing RETURN.

cat >> ~/.bashrc << 'EOF'
export GOPATH=$HOME/go
export PATH=/usr/local/go/bin:$PATH:$GOPATH/bin
EOF

Re-source bash

source .bashrc

5. Download and build

Create folder for NKN

mkdir -p ~/go/src/github.com/nknorg && cd ~/go/src/github.com/nknorg

Clone the NKN repository

git clone https://github.com/nknorg/nkn.git

Change directory to NKN source

cd nkn

Install glide package management

make glide

Download dependencies for building

make vendor

Build the source code with make

make

Testnet config and wallet creation

The configuration of a NKN Node is stored in the config.json file. Fortunately NKN already has a testnet configuration file for you which has only to be copied. Just type

cp config.testnet.json config.json

If you want to create a new wallet for NKN type:

./nknc wallet -c

Test mining

./nknd -p YOUR_WALLET_PASSWORD
