BitCoin Mining – the new cyber frontier

BitCoin Mining – the new cyber frontier



[vimeo 63502573]

thinking about getting into Bitcoins.. Just some notes for myself..

Explain Bitcoins, Silk road and Tor networks..  Should be the first question asked in IT interviews! (cause it shows you are interested in technology and not just memorising brain dumps. ) (also demonstrates you have a hi-tech mind)

Bit coins is a Peer to Peer currency developed like many technology to over-come the inherent problems of “money”. i.e. open source..

Just google it and you will find allot of info.. Its kinda like the old Gold rush days, but your pick and shovel is a sophisticated hardware and software..

These slides pretty good background into bitcoins:

The good old days of bitcoin mining you needed a massive amount of computer rigged together, but now days the technology has evolved to CHIPS.. Check out this crazy rig

But, i dont wana do that, the new ASIC Chips are about the size coffee mug and are more powerful than the above.. So order my equipment and startred these notes.  So the above rig can do 48 GHz, the new ASIC single chip can do 60 GHz..

So to put things in perspective as of this writing, the exchange rate for a single BITCOIN is at @ 15 USD..

[update] I just read this article, (  this guys is the first person to get a asic rig, he going to earn around $240 USD per day.. Of course this will go down, but dame good.. (No tax, not traceable)

So its  a race to the ASIC mining  kinda like the old gold rush days, people gambling, you could loose everything or make a million..  I wish, I got started right at the begging, but i am now keen to put a little investment into this and get it started. I prefer to invest in this rather than give my money to some Finance douche. little side projects are always fun..

As of 20.01.13 – The race is on to develop the first ASIC based mining rings..  These are hardware wired software into silicon, extremely fast and efficient to the point a single chip and can out-power a dozen or so powerful GPU computers. There is also FPGA devices that are available, but that is old technology. I have put my money on BitForce rig and here are the 3 contenders atm:

diskutil unmountDisk /dev/diskN

diskutil eject /dev/diskN

After booting up the Raspberry Pi with the SD card, I checked my router to find the DHCP IP address it gave the Pi.. As I am used a headless Pi. (i.e. I dont have a monitor) the next step is to ssh into it and configure it..   Setup RPi

echo raspberry | ssh pi@[pi_ip_address]
sudo raspi-config

Setup SSH Key Pairs or RP

ssh-keygen -t dsa
ls -l .ssh/
ssh-copy-id -i ~/.ssh/ pi@raspberrypi.local
ssh pi@raspberrypi.local
sudo vim /etc/ssh/sshd_config
#PasswordAuthentication no
sudo /etc/init.d/sshd restart
sudo halt

Install Screen or TMUX or or in order to keep the minner working after logging of a ssh session as my unit is running in headless mode and without console, i need to configure the following:

sudo apt-get install screen
screen bash
screen -r
screen -list
screen -S [name]
screen -D -rr

Setup Wifi Dongle

apt-get install wpasupplicant

Setup Start-up script to auto start minner –

chmod +x /home/pi/
cd home/pi/minner/bfgminer
sudo screen ./bfgminer

# you can have multiply version of the minner from github, i use the above switch for testing mining with the RPi CPU, which would take about 1000 years to get a single bitcoin!!.. good to test passwords and options and pools
