Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority. The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin. Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value. Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers. The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone. Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency. The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies. Bitcoin creator, Satoshi Nakamoto What is the Mining of bitcoin? Technical details : During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized. The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network. Material : In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU. Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time. For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency. A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people. The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins. The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7. Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs. There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology. Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable. Software : There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains. Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner. If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.
To arms Bitcoin community! Help us to complete this mining installation for the Zürich MoneyMuseum. We are not asking for funds. Only your expertise needed! 20$ tip if you give us the relevant clue to solve or mitigate our main problem. Nice pictures of the exhibition inside as well…
Edit: A big thank you to all people who helped us we can now mine true pps with diff1! The people in this thread which have helped most have been awarded. I want to mention also the operator of btcmp.com denis2342 and Luke-Jr. Actually looking at the miner screen in the Linux terminal helped a lot ;-). The pool constantly resigned to stratum with variable difficulty. We can now mine true pps with diff1. Getwork with long polling seems to be default after disabling stratum... We will probably post again, when there is a video of the installation in action... Again many thanks. Learned a lot. Edit: Thank you for all the answeres so far! We will try different things now and report back. Tip bounty will be distrubuted as soon as we found out what finally does the trick. Ths could take a few days. The offerd tip will be distributed and very likeley a few others as well. First of all, let me tell you that the Bitcoin Exhibition at the Zürich MoneyMuseum is most likely the biggest and most diverse of it’s kind. Please read more about the museum and the exhibition below. Help us solve the following problem we experience with our “Muscle Powered Proof of Work” installation: Me and a friend have invested a lot of time to build an installation for the Museum. It is basically a 10GHash/s miner and RapberryPi which is powered by a hand generator (Maxon DC motor with planetary gear). Here are some pictures of the installation, although not entirely put together yet. There are still some changes planned. https://www.dropbox.com/sh/0qcvl3wu4romhnt/AAAYF08lnVAy6W6KEepE7e2Ua?dl=0 Now let’s get to the core of our problem: We are mining at the getwork diff1 pool btcmp.com as it is a true pps pool with getwork diff1. The visitors in the museum can power the generator for 2-3min and see directly how many Satoshis the "network" (actually pool but we don't want to confuse the visitors to much at that point) has given the museum for their work. This all works well so far but one problem remains. Sometimes the pool does not get a share from us for more than 40 seconds or even more than 60 in some cases. I have calculated that with 8.4 GHash/s we should find a share about every 0.5 seconds in average (diff1). I think when the pool gets a share it gets all the hashes as it then accounts for several Satoshis. Statistically we get per minute what we should get in theory. We would very much like to lower the time between the accepted shares by the pool, however. This would help to make the overall experience much smoother for the visitors. Please look at this screenshot from MinePeon and answer some questions: https://www.dropbox.com/s/lb1jei4trc9kqe5/MinePeonScreenshot.png?dl=0 We see that we get a lot of diff1 hashes. However, only 11 shares/packages have been accepted. The Is there a possibility to set the miner SW so it submits to the pool as soon as a share is found? It seems to send them in packages which sometimes have 4-5 seconds in between but sometimes a much as 80 seconds. I would like to submit packages of hashes much more often. How can this be influenced? What exactly are the Getworks (GW)? What exactly are the Accepted ones (Acc)? This is where the TipBounty is. Help us to get a better Acc/diff1 ratio. Best would be 1:1. What exactly are the rejected ones (Rej)? What exactly are the discarded ones (Disc)? What exactly are the difficulty one hashes (diff1)? Now some of these questions seem very very basic but it is important for us to understand what these are and how we can influence these. We have a 1:1 correlation between the Acc and the pool side acknowledgement of shares/packages. So whenever the MinePeon shows one more for this value the pool value for last submitted share goes to “moments ago”. Does the miner SW have a setting where we can set after how many diff1 hashes a package of hashes is sent to the pool? If no, do you have another idea why so few are sent? Ideally we would set it so the diff1 hashes are sent every 5 seconds or so, probably even more often. Is stratum with fixed diff1 possible? If so, would it be better to use stratum? Are there critical settings if we should know of? (we have tried --request-diff and --no-submit-stale) We are using BFGMiner on MinePeon if that matters. We could switch to CGMiner if that would help. Any help is very much appreciated. The museum is doing a great job explaining Bitcoin basics. We had special focus on interactive learning and have several things to underline this. I hope to hear back from you so we can improve our installation. Please don't hesitate to ask if you have further questions. We are both not mining experts. Thanks for reading and AMA.

I see this as a good opportunity for Bitcoin, so let’s embrace it. I am especially excited to compare the traditional forms of money which used proof of work to the new money which also uses proof of work. I think in that context it will be much easier for the visitors to value this concept. A lot of schools and other groups book guided tours at the museum. It is open on every Friday from December 05.

To the moon! Dogemining with BFGMiner, Debian, and ATI.
Visitor from the future! Hello. I'm a newbie digger and recently setup my first dedicated mining box in Debian. I'm not the most experienced Linux user, but the machine had started with Debian Squeeze and I couldn't find its old Windows key. (Also please forgive formatting errors, I'm new to this whole "Reddit" thing as well.) I found a number of guides to misdirect me on my way, so I decided to write up a sort-of (or at least hopefully up-to-date) guide to create a Dogecoin miner on Debian with AMD cards, using BFGMiner to mine coins. Expert digging shibes: I would certainly appreciate feedback to improve this guide. This is not a headless mining guide. I have not reached that level of mastery yet, though I believe it is well within reach. HOWTO
Start by installing Debian Wheezy. Make sure you install the Desktop Environment package. Not only did I fail to make things work when installing X after the fact, but having the web browser will be convenient.
Unpack the BFGMiner source into a directory somewhere.
Open a terminal (shouldn't have to be root), cd to the directory with the BFGMiner source, and run: ./configure --enable-scrypt --enable-opencl
Once that completes, run: ./make
You'll see a lot of output from the build, but if everything goes well you should then be able to run ./bfgminer. You can test it by running: ./bfgminer --scrypt -S opencl:auto -o (pool URL here) -u (your worker's username for that pool) -p (your worker's password for that pool). It won't be very fast, however.
Using your preferred text editor, make a new file in your BFGMiner directory, such as "doge_dig.sh". Add the following: #!/bin/sh export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1 ./bfgminer --scrypt --scrypt -S opencl:auto -o (pool URL here) -u (your worker's username for that pool) -p (your worker's password for that pool)
In your terminal, chmod 500 doge_dig.sh
You can refer to this wiki source to understand the output from BFGMiner 3.10.0. The one gotcha I've observed is that BFGMiner will happily start off showing hash rates in KHash/sec, and after the first accepted block it will jump to MHashes/sec. When I first saw my hash speed appear to drop from "250" to "0.2", I panicked a little before seeing it had changed its orders of magnitude. If you think you're still mining slowly, you might need to bump up the intensity for BFGMiner. Higher intensity means more work, and it's possible to create hardware failures if you set it too high. For my HD 5870s, I use an intensity of 12. You can either set the intensity by adding "-I 12" to the ./bfgminer line of doge_dig.sh, or you can adjust the value by pressing M in BFGMiner and working through the menu system from there. Bonus: Multiple cards What happens if I have multiple ATI cards on one rig, you ask? I had the same problem, and OpenCL would only recognize one of them! It turns out that there's an easy solution, but it costs $1.25 in resistors from your local radio shack: http://www.overclock.net/t/384733/the-30-second-dummy-plug Plug the finished product from there into your second card. If you have more than two cards, you'll need to make one for every card you want to recognize without a monitor attached to it. Reboot and restart your mining, BFGMiner should recognize all of your cards now. In theory, the above technique should allow you to run completely headless, as long as you also install SSH and be sure to have your script export DISPLAY=:0 before running BFGMiner. I haven't tried this, though. Happy mining and welcome to the Moon! I hope this is helpful to someone.
Link to Part 1 Continuing in my attempt to overclock an Antminer U1 to 2.8Gh/s I acquired the replacement resistors, new heatsink, thermal compound, and some Chip Quik to make removing the old SMD resistors a simple task. Heatsink: Enzotech CNB-S1 Thermal Compound: Tuniq TX2 3.74Kohm Resistor: Panasonic SMD 0603 resistor 10Kohm Resistor: Panasonic SMD 0603 resistor The first step was to remove the 1Kohm resistor in the R1 location. After wiping the board down with an alcohol pad, adding flux, and a little dab of Chip Quik on one side of the resistor kept the solder molten long enough to heat up the other side and slide it off the board. Antminer U1 with R1 removed Next step was to clean off the old flux with another alcohol wipe, inspect the board to make sure I hadn't lifted the solder pad, apply more flux and solder in the 10Kohm resistor, followed by the 3.74Kohm resistor. I ordered a bunch of the 10Kohm resistor as they were really cheap, but the tolerance is 1%, so I went through a few resistors on the multimeter before finding a 10.01Kohm resistor. As there was already solder on the pads for R2 it was just a matter of using tweezers to hold the resistor in place while applying heat to one pad. After that it was trivial to just apply heat to the other end and get a good connection. The 3.74Kohm resistor is 0.1%, so I ended up settling on a 3.72Kohm out of the few I ordered. Adding the R1 resistor was as simple as the R2, though I had to add a bit more solder on the side that had been Chip Quik'd. Another clean and inspection resulted in the following. Antminer U1 with replaced R1 and R2 The final step was to chop off the side mounts on the heatsink and drill two holes to mount the Antminer to it. A quick bit of metal cutting with a Dremel got rid of those, and also smoothed off the rough edges. I ended up having to position the Antminer at an angle on the heatsink to get it to fit nicely. A 2mm bit drilled the correct size holes to accommodate the two screws that held the old Antminer heatsink in place. I didn't have to tap threads into the drilled holes as the screws were strong enough to cut into the copper on their own. A small application of the thermal compound to the gold plated area on the back of the Antminer (refer to Part 1 images) and I attached the Antminer securely to the heatsink. Top view of Antminer U1 attached to heatsink Bottom view of Antminer U1 attached to heatsink Bottom view of other side I apologize for the awful camera potato pictures, I'll attempt to get a proper camera and take nicer ones at some point in the near future. Now for the moment of truth, after unplugging all the other USB miners I slotted the modified Antminer and started up bfgminer running the ASIC at stock frequency. After letting it run for about an hour without anything catching on fire or exploding it was time to up the frequency. I slowly upped the frequency to 350MHz to try reach 2.8Gh/s, though at 350MHz I ran into what I'm assuming are power supply issues and the hash rate dropped to 0.8Gh/s, but didn't throw any HW errors. At 300MHz it hashes away happily at 2.58Gh/s with no HW errors, so I'll leave it at that speed for 24 hours and see what happens. Thanks for reading, hope this helps other people overclock their Antminers.
How to fix crashes and low hash rate on my new scrypt rig?
I need help to get past two major problems in my scrypt mining machine (see my config at bottom).
1 problem is system crashes during mining, even with low hash rate
2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs
So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes. On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end): cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65 Here is my hardware config: MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board) Intel Celeron G1620 Corsair RM 850W G.SKILL 8 GB (4GB x 2) Sapphire Radeon R9 280x MSI Gaming R9 280x XFX R9 290x R9-290A-ENFC Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...
Complete noob question. How do I start mining solo with BFGMiner on Windows 7? Explain it like I'm 5.
I have a machine built with Windows 7, and have my Bitcoin-qt wallet. Now all I need to know is how to start mining solo with BFGMiner. I'm not going to join a pool, and most FAQs only list joining pools when starting BFGMiner, but not solo mining. I have no clue how to proceed. Also, are there any other mining software that the community might recommend? Any help would be greatly appreciated. Thanks! EDIT: Okay people. I know about hash rates, ASIC processors, and the diminishing number on returns for mining solo with increasing difficulty. That's not my concern. I just need to know how to start BFGMiner in solo mode to start mining. Anybody have an answer? This is for testing purposes, and my own curiosity. Any help would be appreciated.
I looked at /bitcoinmining and /bitcoin help and both are dead subreddits. Searching through bitcointalk.org is extensively a waste of time as 90% of any conversation are just useless posts. I figured this would be the best place to ask questions. I've set a mining operation and am new to bitcoin mining. I'm getting below my target hash rate by a couple hundred hashes. I noticed in my mining logs every so often I get a some message that aren't errors, but they basically restart the miner from 0 hashes. I have 2 Butterfly Labs singles running the standard 832 firmware and I am using BFGminer 2.7.5. BFL1 took: 20312ms longer than 7000 ms I get this message for both BFL0 and BFL1, and at first I thought my singles were throttling, but the lights are not flashing when this happens. The other message I don't remember off the top of my head, it says something like: "Pool0 not sending fast enough." I use deepbit and my friends who use deepbit don't get these messages. I was thinking I could increase the queued work? Any help would be greatly appreciated.
I currently mine on my 6950 using CGminer, and I get about 430 KH/s at intensity 18. This causes my computer to become close to unusable, meaning that I switch to mining bitcoins when I am on my computer using BFGminer. Is there a miner for litecoin that will have a small hash rate drop in dynamic mode, as opposed to the ~18KH/s that CGminer gets? Thanks in advance.
