Bitcoin Mining on Raspberry Pi2

Introduction: Bitcoin Mining on Raspberry Pi2

Gather The Parts.

You will need a Raspberry Pi 2

A powered USB hub ( Please do not cheap out on this)

Raspberry pi heatsink with fan

Step 1: Credit

Credit goes to jfoo

I really built this though

Step 2: Setup USB and Heatsink

Setup with the USB bitcoin miner to the USB powered hub with fan.

USB hub must be at lest 1.5 - 2.0 amps.

Also the Rpi heatsink and fan. You need this heatsink and cooling fan if you are overclocking the Rpi for maximum mining capability and planning to keep the raspberry pi up 24/7 without burning the core processor.

Step 3: SD Card Setup and Putty

Install fresh Raspian on your SD card with a minimum of 8gb.

Install Putty software and get into the terminal.

As for all Linux machines, update and upgrade.

Step 4: Installation

sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev screen

Use this code to use to install independencies.

cd cgminer
sudo ./autogen.sh export LIBCURL_CFLAGS=’-I/usr/include/curl’ sudo ./configure --enable-bmsc sudo make

sudo ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286

Paste this code in every time you need to reboot the raspberry pi.

Step 5: Pools

You can solo mine or pool mine. I made 20 bucks in 3 days. I recommend Bitminter because of its easy gui.

    i have a beaglebone black, can this rig be implemented using BeagleBone Black

    Your help will be deeply appreciated

    JamesM323 7 months ago

    I don't know much about ras pie, and I looked at this and it looks good and feasiable but then as I went down the page it became Chinese.

    Can someone give me a way to work this for someone who is new to all of this?

    basically step 3 and below.

    i have aurduino. is this transferrable?
    can u help?

    nmrobotics 8 months ago

    no, because a raspberry pi is a full computer but arduino only runs code

    JacoB29 11 months ago

    Hey guys, I am new to bitmining and want to do it kinda on the sideline for an extra buck here and there.

    I was wondering could you use this same technique for a raspberry pi 3 and use 4 usb hubs full of antminers?

    Also, would the code still the same?

    DennisY10 1 year ago

    Hi, can you provide some guidance.

    After inputting the following command.

    /cgminer $ sudo ./autogen.sh export LIBCURL_CFLAGS=.-I/usr/include/curl. sudo ./configure --enable-bmsc sudo make


    . into my RPi B, I get the following errors towards the end of the output.

    ccan/Makefile.am: installing `./depcomp'
    Configuring.
    configure: WARNING: you should use --build, --host, --target

    does this have to be made with antminer u1, u2, u3, or can any miner USB be used I have the latest raspberry PI 3 model b

    mike2016consult 1 year ago

    Hello i make everything but my raspberry pi don`t find my asci miner I use differend model miner What can I do Thank you.

    RockeyDA 2 years ago

    could you please make a totorial on how to do this on a pc? preferably somthing windows 64-bit? i got 2 xeon x5690's and 2 l5506's just folding at home for heat, i would rather get money out of it.

    robertlee0707 2 years ago

    Cpu mining is inificient and gpu mining is power consuming so you wouldnt make any money. Only in the kilahash range. Asics are at the gigahash and power eficient

    RockeyDA 2 years ago

    oh and 1 gpu 250 watts. 2 cpu's 260wats(130wx2) so cpu is a bit harder on power than gpu. i got enough cpu power to smoothly play the amd ping pong demo running the physics on my cpu. sierusly, my posting pic of what i see in taskmgr and what i see on my desk. 4.2GHZ that is going to be maxed 24/7 for 6 months no mater what!

    robertlee0707 2 years ago

    If you would like to cpu mine or gpu mine, I recommend litecoin, ziftercoin, doggiecoin, or anty coin that accepts script. It will be perfect since ordinary asic hardware cant handle it. By the way, use mineral oild and a colling system for the mineral oil. It is about efficiant as water cooling but cooler as in awesome. Nice setup, don't burn the wires

    JamesM323 1 year ago

    also water will oxidize ur computer.

    robertlee0707 2 years ago

    You should have titanX or gtx gforce 980ti graphics card and intel core i7 5960X with an evga titanium 1600W. That will satisfy the hungry graphics card

    RockeyDA 2 years ago

    oh, and if i had a core i7 i could not have 2 prossesors, and i think i could not have more than 8mb l3 cache, plus server hardwere has higher quality chips that last longer than desktop hardware. My x5690's lanch price was 1600$ a piece. i waited 2 years for the price to fall under 200$ a piece on ebay. story of my rig. ballen on a budget gathering parts over years.

    robertlee0707 2 years ago

    Also get them from micocenter since they gave me awesome prices. Just shoutingout. I have a custom built PC and instead of $7,000 awesome cad machine for $4,500

    RockeyDA 2 years ago

    oh, and the coolers were 50$ together cuz i got them on sale.

    RockeyDA 2 years ago

    over the years i have only sunk aobut 1200$ or so in my rig. my dad likes to spend most of my paycheck before i even know it came. so money is still tight after i got a legit job. i dropped 200$ on my gpu in 2012. 450$ on my mobo in 2013, 400$ total on my cpu's, 150$ on ram. 1300w psu was a gift from a firend. if i can find a titan x for under 200$ then its do-able.

    RockeyDA 2 years ago

    dont you understand? flat rate power bill. no heat in the house. every winter i use folding@home for heat, so i can keep it from being 35F inside to 45-55F depending on how cold it is. if i could make mony and heat my house at same time it would be retarted to say no. you miners are all the same, you figured it out and you dont want any one else to.

    robertlee0707 2 years ago

    If you were at the begining of bitcoin, you would make a ton. And i will make a tutorial later on

    For just $400 you can have this Raspberry Pi – and mine bitcoin

    Burning dinosaurs for fun and profit

    Move over, mega-miners: an Andreessen-backed venture is going to beat off your data centre rigs with $400 worth of Raspberry Pi-powered brick.

    Rather than take the magic to the press, the 21 Bitcoin Computer landed direct to Amazon for pre-order by enthusiasts, developers, and suckers.

    Units will actually ship in November 2015.

    For just $US399.99, the 21 Bitcoin Computer gives you your very own Bitcoin coprocessor, complete with command line interface, a 128 GB SD card pre-loaded with a copy of the Blockchain, software, Wi-Fi and USB cable, power supply, and a Raspberry Pi (the latter meaning once you've got sick of waiting for riches, you can at least do something useful with it).

    The Linux-based toy can be run as a standalone computer or connected to Mac / Windows / Linux boxen. The Bitcoin magic happens on silicon designed by 21 running as a co-processor to the Raspberry Pi.*

    That's not how the sellers pitch it, naturally: as the “first” computer with “native hardware and software” support for Bitcoin, “It provides a constant stream of Bitcoin and the software to make that Bitcoin useful for buying and selling digital goods.”

    More usefully, there's also Bitcoin transaction software that the makers say let customers trade the cryptocurrency, offer transaction services, and the like.

    Look, at least you get $400 worth of Raspberry Pi. The 21 Bitcoin Computer

    Vulture South will take the 21 Bitcoin Computer more seriously when we hear that of thousands of them replacing ASIC-based HPC kit in Hong Kong skyscraper data centres.

    Other boosters of the project include Andreessen's partner Horowitz, former Cisco CTO Padmasree Warrior, and former US treasury secretary Larry Summers. ®

    *Bootnote: For clarity, a later edit added the detail that 21 added its own silicon. ®

    Bitcoin Mining Using Raspberry Pi

    Introduction: Bitcoin Mining Using Raspberry Pi

    Want to mine some bitcoins? Want to earn for free? Have a pi not being used?

    Then lets mine some bitcoins!

    Step 1: What Is BitCoin?

    If you don’t know already, Bitcoin is a virtual currency set up in 2009. Bitcoin has grown in reputation over the past few years becoming a very popular as a method to pay for services over the internet. The value has rocketed recently thanks to the huge coverage in the media, for both positive and negative reasons.

    There are two ways to get Bitcoin:

    -Buying them from an exchange, which is the process of converting local currency to Bitcoin.

    -Mining them. Mining is the process of verifying transactions in the blockchain.

    As the whole of the Bitcoin system is decentralised, every transaction is publically viewable within what is called the blockchain. This blockchain contains every bitcoin exchanged between users so, as there is no central server, it has to be self governed. This is the job of the miners.

    Step 2: Requirements

    In order to mine Bitcoin, you will

    Raspbian image SD card

    USB Bitcoin miner

    Step 3: Creating an Account

    There are two things you need to do:

    Download a bitcoin wallet

    Create a pool account

    Set up paymentSet up workers

    Download a Bitcoin Wallet

    A wallet is a program that sits on your computer and gives you a wallet address, this is a unique string of numbers and letters that you will use to receive bitcoins. Download the client for your computer from https://bitcoin.org/en/download

    After installation, you will have to save a file called wallet.dat, keep this file safe, as this contains your unique wallet address within it, including all bitcoins that you will gain. If you lose this file, you cannot recover any bitcoins it contained.

    Create a Pool Account Once you have a wallet address, create a pool account. A pool is a huge collection of other people working towards gaining bitcoins. Due to the complexity of mining a bitcoin, it has become unrealistic to solo mine–the act of processing millions of numbers to solve the block problem. Working as a group, or pool, lets everyone have a chance of earning some Bitcoin. There are many pools around, in this tutorial I’ll be using one called Slush’s pool: https://bitcoin.org/en/download

    Set Up Payment

    Once you have created a pool account, you'll need to enter your unique wallet address into the Bitcoin payout address.

    Create Worker Account

    Next step is to create a worker login account. Within your pool account you have the ability to create something called a worker for each of your bitcoin miners, so you're able to monitor them all separately just in case one should fail.

    Each worker has its own login name and password. Whilst you are on My Accountclick Register New Worker and give it a name, for example; worker, and a password. Now you're ready to set your Raspberry Pi mining for Bitcoin.

    Step 4: Setting Up the Raspberry Pi

    Start with a fresh Raspbian install, if you don’t know who to do this, read the tutorial How to Install NOOBS on a Raspberry Pi With a Mac.

    If you plan on running more than one Bitcoin miner at the same time, it is best to use a powered USB hub. Take into account the power rating as mining will need a lot of power, as much as one mp per miner.

    With your USB miner attached to your Raspberry Pi, let’s get everything installed.

    Step 5: Installing Required Libraries

    The miner to be installed comes as source files, which means that the program must be compiled into a binary before it can be run. To make a program, in this case BFGMiner, many dependencies are required.

    Dependencies are additional software, or libraries the program needs in order to compile properly, as it has been developed using them to make the software more efficient. Hopefully you will be seeing the Raspbian desktop, so double click on LXTerminaland type in the following:

    1) sudo apt-get update

    2) sudo apt-get install autoconf autogen libtool uthash-dev libjansson-dev libcurl4-openssl-dev libusb-dev libncurses-dev git-core –y

    This process will take a few minutes to complete.

    Step 6: Installing BFGMiner

    Once all the dependencies have been installed, now it is time to download and install BFGMiner, so type the following into LXTerminal. It’s normal for these to take a few minutes to complete so some patience is needed.

    ./autogen.sh

    ./configure

    make

    You will be greeted with a screen that looks similar to the following:

    Step 7: Start Mining Bitcoin

    Now you’re ready to start mining. To do this, providing you're using Slush’s pool, you’ll use the following command:

    ./bfgminer -o stratum.bitcoin.cz:3333 -O username.worker:password -S all

    The username section is composed of two parts, the username that you use to login to the pool, and worker which is the worker name you gave when you registered the worker. Finally, the password that was set when you created the worker.

    That’s a lot of numbers, so I’ll make some of them a bit clearer.
    Current mining speed, typically calculated in megahashes or gigahashes. The number of hashes a second that can be calculated the better. A hash is an algorithm of converting numbers and letters into an undecryptable set of characters. So a miner is used to process millions of numbers in an effort to match the hash to guess the original number. The more hashes that can be processed the faster it is able to solve the problem.

    Number of accepted shares. A share on a pool is to show the miner has successfully worked out a given problem, so the more shares you can process the better your reward from the pool.

    Detailed information on accepted shares and pool updates. This is a running log of what is currently happening with the miners and basic pool information, such as messages of updates and when new blocks are found.

    More information can be found at the BFGminer github site.

    Step 8: Conclusion

    Following these steps will leave you with a very energy efficient bitcoin miner, as a Raspberry Pi only uses four watts of power, and a miner is typically 2.5W. Mining used to be done with computers consuming over 700W for the same process so to make a jump in savings helps repay the cost of the hardware we are using.

    All there is to do now is to sit back and watch the money slowly build up. Though it is important that you understand that Bitcoin value fluctuates wildly, it is extremely volatile, so invest at your own risk.

    You can also put up LCDs. Connect more Pis for getting better speed :D

    Bitcoin mining raspberry pi 3

    A Raspberry Pi is a credit card sized $25 (or $45, for the deluxe option) computer, designed for educational use. Has anyone tried running mining software on it? If so, what's the hashrate like? (apparently the CPU is approximately equivalent to a P2 300MHz - I know the hashrate will be very low!)

    Also, can the GPU be used to mine? What's the hashrate for that, if it's been done.

    From the FAQ on the above linked site: "The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. The GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure. That is, graphics capabilities are roughly equivalent to Xbox 1 level of performance. Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics."

    Note: The price of $25 or $45 excludes a way of powering it (via MicroUSB), a keyboard, a mouse and likely a USB hub. I think you need to provide an SD card too.

    The raspberry pi is listed by its processor in the arm section: ARM1176JZ(F)-S. It gets 0.2 Mhash/s when clocked at 800 MHz.

    The Raspberry Pi uses the VideoCore IV series of GPU, which to my understanding are either a single or dual core GPU running at or around 700 MHz. Since the primary benefit of GPU mining is that you can run many parallel processes on the hundreds of cores typically found in most GPUs, the single-core nature of the VideoCore GPU undoes most of that benefit.

    I don't have exact numbers, nor the necessary knowledge to compute an estimate, but I can tell you that the Folding@Home folks already discussed this and came to the conclusion that an AMD Phenom II X4 940 was almost 5 times as efficient for their needs as utilizing both the CPU and GPU of the Raspberry Pi. Since the needs of Folding@Home are very similar (but not identical) to Bitcoin's, it's probably not a stretch to say that if CPU mining (admittedly with a fairly nice CPU) is 5x more efficient, the Raspberry Pi doesn't look like a strong contender.

    Of course, until we have solid MH/s and actual at-the-wall wattage numbers it's very difficult to say if, at scale, a cluster of $35 Raspberry Pis could compete with other setups on initial price or power cost. Personally, I'd guess not.

    The one thing I should probably answer on is about the difference between OpenGL / OpenGL-ES and OpenCL. Both OpenGL and OpenCl can be used for SHA256d hashing, but OpenCl is used much more frequently.

    Where as GL means Graphics Language and CL stands for Compute Language. GL is for graphics and CL is for mathematical and scientific calculations. While your system may have OpenGL support of some sort, it's more than likely doesn't have OpenCL 1 & 2 support for the GP-GPU (VideoCore IV) which would allow you to get okay to medium hash rates. As I see to remember, the VideoCore IV in the Pi doesn't support it in hardware (OpenCL version 1 or 2).

    Which means you'd have to rely on those ASIC miners that are connected via the USB port hub or even a dedicated mining rig that is connected via the UTP network connector (RJ-45 jack / Ethernet).

    Well, at least we're having a good amount of information / data coming out so the next people that read this will have a good idea on what to do with their RPIs if they want to do any mining.

    I will step up and answer the Raspberry Pi question too. The RPI in and of itself is not worth using to do virtual currency mining on by itself. However, if you a nice powered USB hub and connect in the ASICs that plug in via the USB ports and download the proper software that can access these devices, then you've got a descent mining rig to speak of.

    Due to the way in which the ASICs are designed, they can only do SHA256D and that alone although, performance per watt is the best way to go. Essentially, all the RPI does is act as the surrogate for all the ASIC slave units and constantly feeds them data and ferries the data hashes back and forth from their source.

    You can't use Scrypt with these USB ASICs at all. You'll be stuck using the GETWORK protocol until someone can come up with an ASIC that can do both SHA256D and Scrypt.

    One last thing, you may have heard of the Stratum protocol vs. the old GETWORK protocol. This can be used with Scrypt or SHA256D algorithms. Stratum helps you get less stale and has even better network performance than the old protocol.

    Hope this clears things up like my message above.

    I dont think you will find a Pi economic for 'mining', ASICs have far higher hashes per watt. However if you put a Proof of Stake coin on your Pi you can get excellent ROI depending on the price of the coin and the reward structure.

    PoS uses 1 hash per second per UTXO, so even a lowly Pi Zero for $8 can easily run a PoS coin from a hashing perspective (I stake Pinkcoin on mine). The other consideration with PoS and SBCs is RAM, longer chains need to load more into RAM (I believe its the chain index), so for chains with over a million blocks Id recommend a Pi2 or 3, much over 2 million you prpbably need to look into an SBC with higher RAM, like a Rock64.

    Great summary here:

    Also includes a step-by-step guide on how to mine crypto currency on the Raspberry pi

    Do you even know what FLOPS are, first off?

    FLOPS stands for FLoating-point OPerations per Second. Hashes are calculated via signed integers in the form of hexadecimal numbers, those numbers are then run through a series of logical operations (You know; AND, OR, NOR, XOR, NAND).

    FLOPS means absolutely jack when it comes to your processing speed of your Hash Bashing rig (your crypto-currency mining computer).

    ATI cards are known for their single-precision floating point performance over Nvidia, that much is true.

    ATI also has better signed and unsigned integer performance than Nvidia does too.

    ATI has slightly better logical operations per second than Nvidia does.

    Now, floating point is screaming fast on the ATIs as compared to the Nvidia but it's too bad it's not actually being used for SHA256D and Scrypt.

    Integers both signed and unsigned actually take less time on the CPU or GP-GPU to calculate and thus much faster.

    The logical operations are the slowest and since you use a combination of both logical and unsigned integer you get a composite average of the performance between the two and of course the implementation of the mining application.

    If it's done correctly, you should get around 85 to 90% maximum of what your card or embedded system claims it's capable of doing. Simply put, you will never achieve 100% because you have an operating system that is using the card and of course interfacing to the rest of the system.

    While the indicators tell you are getting 100% of the cores, what it's really means is that you are getting 100% of the 85

    90% theoretical maximum you can achieve with the hardware you have.

    PiMiner Bitcoin mining machine

    Email arrived from LadyAda on Friday. In between the usual advice about good Korean barbecue technique and pointers to cool things that just happen to be conductive, she mentioned that Adafruit have been on a real roll this week with Pi projects. You’ll already have seen Adafruit’s Onion Pi, a Pi-based wireless Tor proxy. Staying within a topical theme, here is Adafruit’s newest Pi undertaking: a Bitcoin miner.

    If you’re not sure what a Bitcoin is or why this is interesting, head over to read Gizmodo’s explanation (which offers a nice simple breakdown), or look at the Bitcoin Wiki before you go any further.

    The Pi on its own isn’t an efficient Bitcoin miner; some people are using it as one, but more as an example of how mining works and a bit of a novelty than as a genuine way to raise funds. (If you’re going to be mining Bitcoins, you’ll fall into one of two groups: people who do it for fun and who don’t mind whether they make money or not; or people who take it very, very seriously and approach it as a business.) What you really need if you’re trying to make money out of the enterprise is a custom ASIC device, which has a much higher hashrate than something like the Pi. And it turns out that the Pi is a very cheap and efficient way to control and monitor devices which are better suited to mining Bitcoins – like the new, thumb-drive-sized ASIC Bitcoin miners that have started appearing on the market recently, which mine at a similar rate to a fast graphics card. Enter the PiMiner.

    Adafruit have a detailed tutorial on setting up the Pi to act as a headless controller and status monitor for your mining devices, with information on uptime, hashrate, error rate, share data, and network difficulty displayed on an LCD screen attached to the whole device.

    I know several of you are already using Pis to mine, and that others are building FPGA mining platforms with the Pi. We’d love to hear more about how you’re getting on – please let us know in the comments!

    Repair the Yahoo Search App.

    Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

    I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

    I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

    I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

    We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

    I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

    I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

    I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
    No matter what I search for or website thru the Yahoo Search App it says the following after I searched for

    Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

    For just $400 you can have this Raspberry Pi – and mine bitcoin

    Burning dinosaurs for fun and profit

    Move over, mega-miners: an Andreessen-backed venture is going to beat off your data centre rigs with $400 worth of Raspberry Pi-powered brick.

    Rather than take the magic to the press, the 21 Bitcoin Computer landed direct to Amazon for pre-order by enthusiasts, developers, and suckers.

    Units will actually ship in November 2015.

    For just $US399.99, the 21 Bitcoin Computer gives you your very own Bitcoin coprocessor, complete with command line interface, a 128 GB SD card pre-loaded with a copy of the Blockchain, software, Wi-Fi and USB cable, power supply, and a Raspberry Pi (the latter meaning once you've got sick of waiting for riches, you can at least do something useful with it).

    The Linux-based toy can be run as a standalone computer or connected to Mac / Windows / Linux boxen. The Bitcoin magic happens on silicon designed by 21 running as a co-processor to the Raspberry Pi.*

    That's not how the sellers pitch it, naturally: as the “first” computer with “native hardware and software” support for Bitcoin, “It provides a constant stream of Bitcoin and the software to make that Bitcoin useful for buying and selling digital goods.”

    More usefully, there's also Bitcoin transaction software that the makers say let customers trade the cryptocurrency, offer transaction services, and the like.

    Look, at least you get $400 worth of Raspberry Pi. The 21 Bitcoin Computer

    Vulture South will take the 21 Bitcoin Computer more seriously when we hear that of thousands of them replacing ASIC-based HPC kit in Hong Kong skyscraper data centres.

    Other boosters of the project include Andreessen's partner Horowitz, former Cisco CTO Padmasree Warrior, and former US treasury secretary Larry Summers. ®

    *Bootnote: For clarity, a later edit added the detail that 21 added its own silicon. ®

    How To Build A Raspberry Pi-Based Bitcoin Mining Rig

    While you won’t get rich running a single Raspberry Pi Bitcoin Rig, you can probably make back your initial investment in this ingenious little machine. RaspPi Bitcoin rigs are nothing new but Dave Conroy has just built one and, more important, shared his plans in a fairly easy-to-read page.

    The system uses the Pi as a main processor and a 330MH/s ASIC. In total he spent $127 on his kit and, as far as we can tell, the power outlay will be negligible.

    The system uses an ARM-centric mining OS called MinePeon. It is basically a version of Arch Linux ARM with a few mining apps thrown in. Then all you need is a Bitcoin wallet and a little bit of time. Given that you’ll be mining at a maximum of 330MH/s, you probably will be seeing pennies a day, if that. If you’re absolutely new to Bitcoin, you can learn a bit more about how to set up all the accounts and wallets here. I think the real point, however, is the novelty of the kit.

    It’s cool to see this little rig running and I think the wee USB-powered fan on top of it is the crowning touch. Put a couple dozen of these in a room and you could probably really do some damage and your farm will look sort of like Pikmin, which is a bonus.

    Bitcoin farming – on a industrial scale

    Jetlag’s grim. As you’ll have gathered from Ben’s post on Monday, I found that I was so tired on Monday I couldn’t speak coherently, much less read or write. So I ended up spending the day going through some YouTube videos I’d been pointed at, having decided that this required less energy than typing.

    One in particular demanded to be shared.

    Here’s a segment from KOMO 4, a Seattle news station. Last week’s news about the collapse of Mt Gox, one of the largest Bitcoin exchanges, has meant that there’s been lots media interest in Bitcoin, and this video talks about what it is…and, in doing so, visits one of the US’s biggest Bitcoin farms. We were struck dumb (really – jaws resting on chests, drooling slightly) when we saw the footage of how they’re mining: that’s an awful lot of Pis, and even more ASIC miners. We don’t think we’ve seen so many Raspberry Pis in one place outside the factory in Wales where they’re made. Fast forward to 3:08 for a detailed look.

    Anyone know what ASIC’s they’re rigging up to the Pi’s?

    In the discussion at /r/bitcoin, someone claims that each Raspberry Pi manages 16 BitFury ASICs.

    Each board has 16 chips, each RPi can hold 16 boards

    so a total of 192 Bitfury Chips per Raspberry Pi

    This is Daves site but looks like he might be getting out of the Hardware Business

    Also the Bitfury rev 2 chips are out and they perform at a higher hash rate and lower power consumption

    I will the RPi has better USB support, 3.0 would be a game changer if they could manage to also upgrade from a ARMv6 to something better supported on debian

    Hit me up on twitter if you have more questions

    Crikey – that’s a lot of bitcoin mining. $8M/month….

    I guess the Pi’s are managing the FPGA’s rather than mining themselves.

    Looks that way: I’d love to see more detail about what’s going on there.

    We’re also interested. Could convert the stock rooms into BitCoin warehouses :)

    Looking closely at the video, it looks like there’s 16 chips per board, and 16 boards per Pi. I’m guessing the Pi is effectively acting as some kind of low-cost chips->ethernet bridge?
    Damn impressive! 8-)

    That’s what I was thinking Jamie :-)

    8M a month is an awful lot. How much do you reckon it cost him to set up?

    I wondered the same thing.

    25000 BitFury cards @ $(350/card + $150 extra hardware (cables, racks, etc)/card)= $12.5M
    +

    1400 kW * 24 hours/day * 30 days/month * 0.131 $/kWH = $132K/mo power
    + rent/cooling = ?? (another few hundred K or so?)

    In any case, if he’s generating $8M/mo in BTC, I’d say he’s doing “very well” indeed. :-)

    Hmm… Maybe it’s time for me to quit my job and get into this racket …

    If he is using the 16xBitFury ASIC boards (which do 40 GHash/sec), then 1PHash means 25,000 boards. At 16 boards/Pi, that’s 1,562 Pis…. wow!

    That’s about 1/2000th of all Pis ever made. In one place.

    8 million buys a lotta Pi

    Most of the money is for the BitCoin mining boards, not the RPIs

    I know it is the cold reality of life, but imagine what good could be done if the results of the processing is actually useful.
    [I assume there isn’t any practical use the results of bitcoins – except as part of some Alien supercomputer we are unaware of]

    Time to make a virtual currency based on DNA sequencing or cures for cancer.

    This is @meltwater, limited comment depth and all:

    The computation they’re doing is to confirm the block chain by finding a hash of the block that has certain properties. This is useful to BTC itself and without it there’s no bitcoin. If they did switch to an externally useful bit of computation it would no longer be securing the network. There’s not really a way to both have the computation secure the network and have it be externally ‘useful,’ and in reality BTC is nothing but the ledger/blockchain.

    I don’t understand why the need for Pi’s if they are actually using a ASIC. It makes absolute sense if using a FPGA, but not for an ASIC.

    I’m guessing the media has made a mistake or he is calling them ASIC just to prevent others from attempting the same.

    Pi are needed to run CgMiner application that controls ASIC boards

    This is sick! I wish i jumped on the wave back in 2011!

    Pretty sure it’s this setup I think they sold for 15,00 EU months back looks like he bought them all up.

    If you want the inside scoop.

    But you didn’t hear any of this from me ;)

    I think it was all outlined there.

    Interesting reading. Lets sum this up if I can. :)

    First chip test inconclusive
    So far we had only very short time to test the chips locally in Taiwan and we were not able to communicate with it. The provisional dead bug setup was sufficient to evaluate leakage currents but we were not able to create a functional level shifter to transmit messages between it and raspberry pi. We fly the chips to EU now. The test will continue on Sunday night.

    Only 6 days to get things sorted out.

    500TH/s reached
    Created on 2013-12-15

    If you piece this all together they created the whole rig and put the Pi at it’s head. Could be the Largest Pi Operated Company in the world right? Some 2,500+ Pi’s maybe? How many 3.14’s in 500TH/s.

    Picostocks and Megabigpower seem to be the same group of people and the force behind what is probably the largest Bitcoin farm in the world. Thanks to the low power consumption of the Pi.

    Unfortunately it looks like a risky investment to me.

    1GH/s per share
    We are now operating above 500TH/s and this is roughly equivalent to 1GH/s per share. We will keep this average hashrate from now on.
    The mine has generated 18622 BTC in revenues so far. We expect to break even end of this year and reach the total revenues of 20730 BTC (0.04BTC IPO price * 518271
    shares).

    I need an investment counselor at this point. To crunch those number. I know you guys will be busy with your maths after this goes live. :)

    Shades of Colossus and Bletchley, Just imagine if those ASICS were cryptobusters rather than miners.

    One of the clever design decisions was that it is astronomically more profitable to mine bitcoins than it is to try and hack a single bitcoin-account with the same hardware.

    The more I learn about bitcoin the more impressed I’ve gotten with it. It really is very, very clever and it does make our current money-system look rather silly.

    Matlab 2014a was released today. New feature: Raspberry Pi and webcam hardware support packages.

    Seems that money really motivates people :-). Maybe the bitcoin algorithm is part of a decryption effort on some secret alien communication signal. Well, it’s more fun to suppose that, than some mundane currency.

    Well the mathematical model of gold and it’s mining is just the first experiment on the bitcoin-protocol and network. The technology and design ideas behind bitcoin go far far beyond just money, but even just that aspect is plenty powerful.

    Imagine being able to bring a somewhat reliable contract/payment system to the entire world (yes not just the affluent West), that does not require “trusted” third parties, is not a prospect to sniff at. For me personally and many in the bitcoin-scene that is one of the primary motivations for being interested in it. If you can point me to a project that has more potential to improve the world than bitcoin I’d be happy to learn about it.

    One potential problem is that it’s never possible using exhaustive testing to find the “last” bug in any implementation with more than a few lines of code. The WiFi WEP encryption implementation was based on a sound theoretical footing (at least as far as mathematical proofs can be performed, which is not to perfection), but it contained a fatal bug that rendered every IEEE 802.11b WiFi access point vulnerable to a brute-force attack that would take less than a day to crack, worst-case, using a common laptop of the time. The German Enigma and Japanese Purple codes were theoretically unbreakable, but suffered from operational and implementation flaws that made them sieves without even needing brute-force attacks – Colossus was primarily just a high-speed means of decryption (much faster than the manual methods used by intended recipients), not a means of brute-force attack. The Merkle-Hellman trapdoor-knapsack algorithm seemed perfectly fine for use in a public-key encryption system, but it turned out to have a fatal flaw that wasn’t discovered until after implementations were in use. Debugging software implementations is hard enough, but when the algorithms are encapsulated in hardware such as an FPGA or an ASIC, the challenge of eliminating bugs becomes astronomically more complex. Unwarranted confidence in technology that is impossible to verify end-to-end is a recipe for potential extreme disappointment, and when finances are made dependent on it, well, I think P.T. Barnum had something to say on the subject.

    To me that sounds like one more reason we need bitcoin and numerous alternative implementations, so we have alternatives.

    Money has allready become digital anyways and I’m not that convinced of the safety of monolitic central hubs. At least with the distributed model the risk is distributed, the current central points of failure structure is way more scary.

    Also I’m more worried about the cryptography securing atombombs than bitcoin, at least bitcoin is currently at best only money.

    Enigma wasn’t perfect there was a small bit of information leaked by the system’s design. One large flaw was that a letter in the substitution portion of encryption, which was achieved by a plug board, a letter would never be mapped back to itself. That creates a tiny leak of information that helped bring down the whole system.

    I dunno… investing in bitcoin sounds like investing in tulip bulbs… What’s the worst that could happen?!

    Exactly the point I’ve made many times elsewhere. Read “The Black Swan: The Impact of the Highly Improbable” by Nassim Nicholas Taleb to see why the collapse of Mt. Gox is not only predictable, but inevitable, not because of the technology, but the wetware that somehow always winds up abusing it (“It’s different this time.”, “We’re professionals, we know what we’re doing.”, etc.). See also the Hans Christian Andersen tale, “The Emporer’s New Clothes” to see what lemmings will do when it comes to cliffs. Placeholders for value (financial instruments such as money) have no intrinsic value in and of themselves, no matter how rare they are. It’s only confidence (as in “confidence man” or “con man”) in the instruments that conveys any worth to them, and that can be quite fleeting, as booms/busts in Mt. Gox, real estate, financial markets, commodities, currencies, tulip bulbs, probably caveman furs, etc., have so vividly demonstrated over the eons.

    The point being? Everything’s a bubble and everything must die. Hardly a surprising observation, but also not a very motivating or constructive mindset. It also doesn’t make bitcoin any less interesting.

    Funny how people seem to have a religious fate in our current financial system, but when you look closely it seems to have even less “intrinsic” value as bitcoin.

    There’s a distinct difference between the current financial system and the new ‘non-guaranteed’ e-money like bitcoin et all: the new system has collapsed in just 3 years or so, the old one survived for centuries, and counting :P

    Monetary systems rely on confidence and trust, as said before. Confidence that the unit in which you trade will keep it’s value over a longer period of time and trust in the issuing authority that their guarantees on the unit are kept. The only organisation that can fulfil that promise is a government. There is no issuing organisation of e-money, so no-one guarantees you the value of the unit(s) you own. :(

    While you are partially correct (your references to confidence being the support of the current global currency systems), you neglect to account for the disheartening fact that our current global currency system is no less a “con” scheme than BTC. Speak to any knowledgable financial advisor (which I am, admittedly, not) and they will tell you that U.S. currency is fiat currency, which is to say, it is not backed by anything tangible.
    The U.S.D. has been the global reserve currency since WWII, which was fine until about 1971 when Nixon took us off the gold standard and gave the Fed the authority to issue “Reserve” notes (“Federal Reserve Note” printed at the top of every bill) that are not backed by any tangible assets. This was a departure from the previous standards of gold- and silver-backed notes that had been issued in previous generations, which could be taken to any bank at any time and exchanged for the current market value of the note in gold or silver, respectively.
    Therefore, the current financial system is no more inherently stable than BTC.

    Unlike tulip bulbs, Bitcoin is not an asset. Instead, it’s a public ledger transaction platform.

    It’s very problematic to look at Bitcoin as an asset or even merely as currency. It’s also currency, but that’s not its only role. It manages transactions. And within those transactions, it can carry information that is verified, timestamped (not unlike a notary), and protected (changes can’t be made to the ledger, and falsified transactions are immediately detected).

    Comparing it to the tulip craze is unfair and very inaccurate. (But so is comparing it to gold or any other asset.)

    Mining bitcoins is becoming a fool’s errand, but there’s always some new piece of hardware coming out that allows those hard-core miners to keep ahead of the curve. One such piece of hardware are new custom ASIC devices that are just as fast as an FPGA while being much less expensive. A lot of these ASIC devices come in interesting packages that look just like a large USB thumb drive. Of course this is the perfect opportunity to show off what the Raspberry Pi can do by mining Bitcoins at rates comparable to the best graphics used in mining today.

    The Raspberry Pi simply doesn’t have enough horsepower to mine bitcoins at any worthwhile rate. There are, however, USB ASIC devices that will mine for you at about the same speed as a high-end graphics card. Since multiple ASIC devices can be controlled through a USB hub, it’s simply a matter of plugging a USB hub into a Raspberry Pi, loading up CGminer, and letting your new PiMiner loose on a mining pool.

    The Adafruit Pi Miner uses one of their really cool LCD character displays and keypad to display the current mining rate, accepted shares, and enough information for you to calculate how long it will take to break even with your Pi powered mining rig. How long that will be for this four device rig we’ll leave to the comments section.
