Skycoin:

Skycoin is a premier project that utilizes blockchain for a newly decentralized networking protocol, replacing IP addresses with public keys for end to end encryption. This revolutionary blockchain has the potential to completely overhaul the current internet & evolve into a "Web 3.0". The implications & real use cases for an earnest change, not only in how we interact in a peer to peer setting, but also putting forth the infrastructure necessary for community based, community controlled networking. If bitcoin was the prototype for decentralized economics; Skycoin is the expansion of that methodology. Skycoin improves on current consensus algorithms with the implementation of Obelisk & the addition of a hardware solution known as the Skyminer. The Skyminer is one of, if not the only physical product a blockchain project has shipped to integrate blockchain solutions into tangible real world obstacles.

Skyminer:

The Skyminer is the hardware platform for the implementation of a decentralized internet. When Skyminers are built the users deploys skynodes that will provide bandwidth for the network. In turn the user's will be paid an allocation of Skycoin for their services. This is an introduction to the Skycoin economic model. Where Skycoin community members are compensated for their role in the implementation & expansion of a new internet protocol.

Building a D.I.Y Skyminer:

The following is a guide for users who want to be involved in the early implementation of Skywire.

Parts List:

8X ODROID C2

8X Samsung 32GB EVO Plus Class 10 Micro SDHC

8X 1FT Micro USB to USB Charger Cable

8X 1FT Cat6 Ethernet Cable

2X GeauxRobot Raspberry Pi 3 Model B 4-layer Stack Clear Case Box Enclosure

1X TP-Link 16-Port Gigabit Ethernet Unmanaged Switch

1X Anker 60W 10-Port USB Wall Charger

1x Tmobile TM-AC1900 Router

Why the ODROID - C2 instead of a Raspberry Pi / Orange Pi Prime ?

Currently as of this writing, Orange Pi Primes are out of stock, the aim was to find a board that was similar or better while still staying compatible with the software necessary to run the nodes. The ODroid-C2 was the perfect mid range between an Orange Pi Prime and other boards such as the current line of Rasberry Pi's. The ODroid-C2 also utilizes the same form factor as the readily available Raspberry Pi, which made finding a case for a cluster easy. Below are the side by side specifications for each board.

Installing AsusWRT Merlin on your TM-AC1900 Router

See directions Here

& further direction Here

Installing the Operating System on the Micro SD Cards

Download & install the latest Etcher software for your system

Download & install Armbian for your board, you may need to unzip file

Download & install Putty, later on you will use this to SSH into the Odroid boards

Insert your card into the computer using your MicroSD to USB adapter

Open Etcher; your microSD should automatically populate, select the Armbian image you downloaded earlier & click "Flash!"

Eject your microSD card from your PC (Safely)

Repeat for the next seven microSD cards

Install microSD cards into each Odroid C2

Hardware Setup & Installation

Install your Odroid's into a cluster using the clear acrylic enclosures

Install the 1FT USB power cords into the micro USB ports on the Odroid's

Install the CAT6 ethernet cables into each Odroid Gigabit ethernet port

Connect your usb cables to the Anker power bank

Install each ethernet cable into the back of the 16-Port Gigabit Ethernet Unmanaged Switch

Connect an ethernet cord from the yellow LAN port to your 16-Port Ethernet switch

Assign Static IP's to Odroids (AsusWRT)

Open a browser and navigate to 192.168.29.1 (or the default IP address of your router)

Select LAN under Advanced Settings > DHCP Server tab >Enable Manual Assignment > Yes

In the DHCP section you may select the drop down menu under "Mac Address"

Select your Odroid's IP address and change the Hostname to Odroid No.1

Do the same for the other Odroid IP's numbering them perspectively

Write down the IP addresses of your Odroids for later use

Armbian Configuration

Open Putty to SSH into your Odroids

Enter the static IP for your first Odroid

login: root

password: 1234



Once you login you will see prompts to change your password

Enter the default password "1234" and then proceed to change your password

You will be prompted to create a new username and password

Follow directions on the command line to create a username and password

No need to enter in your name and personal information, click enter until asked to save, then type "Y" and enter again

Update Armbian using the following commands

sudo apt update

sudo apt upgrade







Install & setup Skywire Nodes

SSH into your first Odroid

Login with root and your password

Enter the following commands after logging into your Odroid

cd

curl -L https://dl.google.com/go/go1.10.linux-arm64.tar.gz

cd /usr/local/

tar xzvf /root/go1.10.linux-arm64.tar.gz

ln -s /usr/local/go/bin/go /usr/local/bin/go

ln -s /usr/local/go/bin/godoc /usr/local/bin/godoc

ln -s /usr/local/go/bin/gofmt /usr/local/bin/gofmt

mkdir -p $HOME/go

mkdir -p $HOME/go/bin

mkdir -p $HOME/go/src

mkdir -p $HOME/go/pkg

cd ~

vi .bashrc





Edit the file by pressing "I" to edit

Navigate to the bottom of the file and add the following to the file:

export GOROOT=/usr/local/go

export GOPATH=$HOME/go

export GOBIN=$GOPATH/bin

export PATH=$PATH:$GOBIN

Press ESC and type ':wq!" to save the file and exit

to continue enter the following commands

source ~/.bashrc

go get github.com/skycoin/skycoin/...

cd $GOPATH/src/github.com/skycoin

git clone https://github.com/skycoin/skywire.git

cd $GOPATH/src/github.com/skycoin/skywire/cmd

go install ./...

apt install tmux

Enter "Y" and press enter

Enter in command line

reboot now

Start a new Putty session

Insert the following code into command line

cd $GOPATH/bin

tmux

./manager -web-dir ${GOPATH}/src/github.com/skycoin/skywire/static/skywire-manager

start a new putty window

cd $GOPATH/bin

tmux

./node -connect-manager -manager-address :5998 -manager-web :8000 -discovery-address messenger.skycoin.net:5999-028667f86c17f1b4120c5bf1e58f276cbc1110a60e80b7dc8bf291c6bec9970e74 -address :5000 -web-port :6001

Now navigate to your browser

Enter the IP address of your first Odroid, at the end add ":8000"

Example "192.168.1.132:8000" assuming 192.168.1.132 is the static IP of your first Odroid

The following page should display:

The default password is: 1234

Once logged in the skywire manager should display your first node, its status and the public key

Installing Nodes 2-8

Repeat all steps after hardware setup using the new IP address you setup in AsusWRT

Once you get to the last command after starting your second Putty session

At the end use the following code instead of your prevous ./node-connect-manager code

Replacing "ODROID IP ADDRESS" with the Ip address of your new Odroid

./node -connect-manager -manager-address "ODROID IP ADDRESS":5998 -manager-web "ODROID IP ADDRESS":8000 -discovery-address messenger.skycoin.net:5999-028667f86c17f1b4120c5bf1e58f276cbc1110a60e80b7dc8bf291c6bec9970e74 -address :5000 -web-port :6001

Repeat for the next Odroid until you've completed all eight nodes

The Skywire manager should show all 8 nodes as "Online"

Enjoy paving the way for the next generation of internet
