ROKOS v3 "core" Screen Shots



"ROKOS" Initial Setup

1.- Download and Burn the ROKOS Image to a micro SD Card like you would with any other Pi Distro.

Dec 18 2015

Steps for first boot

a) Login with user: root password: raspberry (*security note: only use the root account to make this steps, do not use clients on root)
B) Open Terminal, type: raspi-config
c) Set your Time Zone and Expand the file system, restart.
After restart the system will auto log to the pi user desktop.

Welcome to the ROKOS Desktop

Security Steps
Pi and root accounts default passwords: raspberry

*note: Remember that on terminal the password will not be displayed as you type it; there are no Windows-style * symbols representing the letters. Instead, it will appear that you haven’t entered a password. This is a security feature to prevent people guessing the length of your passphrase. Just type the password regardless.

Open a terminal and change the password of "Pi" and "root" accounts with this commands

sudo passwd
(write your new password, this will change the password of Pi, the main use account)

su root
enter password: raspberry

(write your new password, this will change the password for the root account)

(leaves root account and goes back to Pi account)

exit or close the terminal window

RESTART the system one last time so it can start with correct configurations. (correct mount of tmp for the tech savy)

Final steps / BTC and OK Clients

a) OK: Go to Menu > Internet and Click on the OKCash Wallet

This will open the OKCash wallet, give it some minutes for the initial setup, OK Chain is Synced so it will be ready for use in the next minutes.

B) Go to Menu > Internet and Click on the Bitcoin Wallet

This will open the Bitcoin wallet with the option to select where we will be saving the BTC chain.

*For BTC the initial sync will take some days, wallets are fully usable after being fully Synchronized.


B) Make a backup of your wallets and save in USB or external media.

Use your Bitcoin wallet to plug HW and mine BTC, Send/Receive BTC cryptocurrency, become a full node and support the Bitcoin newtork, etc.

Use your OKCash wallet to Stake/Mine OK, Send/Receive OK cryptocurrency, send and receive private messages with other OK users, etc.

Important Security Notice:
Remember to create a backup for your Wallets, you can use the wallets to create them and save in different folders on a USB device.
You should ALWAYS have a backup of your wallet, Raspberry Pi Hardware, Raspbian and ROKOS Software are under development hence not responsible for missuses, electrical or compatibility issues that might cause a loss of information. It is as secure as one's ability to take care for it, same as a computer, so always have a backup of your wallets on an external device.


You can start testing and developing new integration with the Bitcoin and OKCash Tech for your IoT projects.

ROKOS v4 Released - New article by The Merkle News

ROKOS Is A Free Raspberry Pi Operating System To Launch A Bitcoin Node

Bitcoin users from all over the world have been looking for cheaper alternatives to create additional network nodes. Up until now, the only options were to either use a [previous] computer or laptop, or buy one of the pre-configured – but rather expensive – Bitcoin Node solutions running on a Raspberry Pi. ROKOS v4 might be the solution some people have been looking for, as it will turn any Raspberry Pi into a Bitcoin or altcoin node.
