Generally, it's not worth your time and effort to mine at home! (Some exceptions may apply.) Age of ASIC mining CPU mining has been unprofitable since 2011, GPU mining just slightly later. Today, ASICs rule mining. The Bitcoin network has more than 1.7 Ehash/s (Oct 2016) now which is 1,700,000,000,000 Mhash/s. Your graphics card will be running full ...

Javascript has access to OpenGL ES, including shaders, so it has access to programmable parts of the GPU at nearly native speeds. I think that a smart kid might be able to build a fragment shader that does SHA256 hashing, which outputs to the stencil buffer, so that Javascript has a 2-way communication channel with the GPU. So yeah, you could probably use ...

You're using the wrong hash algorithm for Bitcoin mining. Bitcoin uses SHA256d (d = double), but cpuminer (at least the version 2.3.2 on my system) defaults to scrypt (for Litecoin) instead: -a, --algo=ALGO specify the algorithm to use scrypt scrypt(1024, 1, 1) (default) sha256d SHA-256d Slush's pool ...

AWS is rental of server instances. Servers without GPUs. Bitcoin is not cost effective when mining using CPUs, so nobody has done that analysis for nearly two years because its an obvious money loser and becomes a worse option with each passing day of rising difficulty. Now EC2 (compute cluster) does use GPUs but NVidia GPUs which don't perform at a ...

Any CPU can still be used to mine Litecoin, although much less effectively as a modern AMD GPU could. Mining with a CPU gives you very bad hashrate therefore I wouldn't recommend it. Even a high end CPU will not give you the hashrate of a mid range GPU. You should use a graphics card (GPU) to mine litecoins or switch to another coin Additional Information:...

It's definitely not against the law. It might be breaking the terms of service (ToS) but there's really no reason why any dedicated server hosting provider wouldn't allow you to max out the CPU. I wouldn't do business with them if they limited that. However, you need to read your hosting provider's ToS. They might forbid certain applications like IRC servers,...

Have you tried understanding why you have that desire? It might help you understand more about what makes you tick. You might like to try mining Litecoins, or even on the Bitcoin Testnet. Or, you could try some Bitcoin mining with the Eligius pool, which from memory will pay out any amount after 2 weeks (whereas most pools have a minimum payout). If you can ...

There are several options for Mining Bitcoins some of these are no longer profitable, but for the sake of being thorough here they are in order of efficiency lowest to highest: Methods CPU Mining (minerd) GPU Mining (cgminer, bfgminer) FPGA Mining (Custom software - https://github.com/fpgaminer/Open-Source-FPGA-Bitcoin-Miner) ASIC Mining (cgminer, bfgminer,...

For Mac OSX users, you must have Snow Leopard (10.6) or newer installed. A fully-connected BitCoin wallet. see http://bitcoin.org/ If this is the first time you have launched BitCoin, it must download and verify all the existing blocks in the system. This can take an hour or longer - just ignore it for a while. Update: since the time of this ...

Well, you can TRY mining. To see how much coins you can expect, check your computer's GPU on the Wiki page, get its hash rate, and plug that into a profitability calculator, such as mine. This can give you an idea of how many coins can you expect to mine and whether you would get any profit from that. Unfortunately, most likely you won't be able to mine at ...

Can i do mining with a normal PC? Yes, you can. I don't have too many expectations. Maybe 0,1 in one week? No, not possible. You will effectively compete against all computational resources on Earth, that are now cracking this nut. If I can estimate, a humble home PC will produce around 1 - 100 MH/s, based on CPU or GPU mining stats. This range covers ...

I wouldn't suggest to mine with your laptop further more I wouldn't mine with a CPU any more. Your laptop can damage quite fast, because mining is very hardware intensive and it can overheat your components. After some time they will get damaged because they are not build to hold that power over a long period of time. Your hashrate is quite low. With ...

The bitcoin community would have to decide that they don't particularly care about having significant security anymore. ASIC-resistance weakens the security of proof of work chains because it eliminates the need to invest in a chain in order to attack it. Someone who owns lots of expensive ASICs will not want to let them be used to attack the chain they are ...

You can install the standard Bitcoin-QT client, navigate to \Program Files (x86)\bitcoin\daemon\ and then run bitcoind -gen=1 However this isn't recommended except on the Test network because it is next to impossible to generate any coins this way on the production network.


7

Testnet is designed to test Bitcoin software - including parts that have to do with finding blocks. As such, it should be easy for developers to generate testnet coins. Because of this, it will be easy to solo mine on a CPU to generate them, and you should not use anything heavier than that because you would ruin it for everyone else. It is also not ...

It would not at all be useful for Bitcoin mining. However, it may be useful for other digital cryptocurrencies, such as Litecoin or PPCoin.

http://blog.brycekerley.net/post/5338746136/bitcoin-mining-on-amazon-ec2 Here its explained at best, that it is NOT profitable even on the GPU servers ;)

It is likely that neither is profitable for you, because ASIC miners are alot more effective than any GPU mining, which in turn is alot faster than CPU mining. But don't take my word for it. This hardware comparison wiki is a good source to make an initial estimate. There is one entry listing the combination of an A10 and a HD7660G GPU, claiming to get 105 ...

Litecoin is the 2nd most popular currency in the same family as Bitcoin, and: It is based on the Bitcoin protocol but differs from Bitcoin in that it can be efficiently mined with consumer-grade hardware. Litecoin provides faster transaction confirmations (2.5 minutes on average) and uses a memory-hard, scrypt-based mining proof-of-work algorithm to ...

To be honest, you came in a little too late. Mining is now done by ASIC's (Application Specific Integrated Circuit). These are chips (like the ones Intel and AMD make) that are only capable of hashing SHA-256. These chips are very limited (they can't run any other software), but can do what they were made to do extremely fast. An Intel 'universal' CPU can ...

Here, a nice explanation (even if the post is old) http://www.righto.com/2014/02/bitcoin-mining-hard-way-algorithms.html

You can always try the testnet it is really easy to mine on it since difficulty gets reseted to difficulty one. Just start your bitcoin client with the -testnet parameter (and -gen if you want to CPU mine)

CPU mining is DEAD. GPU mining is DEAD. Even FPGA mining is DEAD ! ASIC's ? Yes them still can be profitable. But..... ONLY if you can get your ASIC cheap. Here are the maximum prices you can pay for ASIC, and still have some hopes to get ROI in 3-4 month: 40+ GHs for 1BTC - if you get your machine TODAY 75+ GH/BTC - if ASIC delivered within 1 month 160+...

Yes Erik, the mining feature is still built-in and you can check how many hashes your CPU can perform. Although it's pointless and you cannot earn anything, it is still a fun experiment that people like to try. If you have a bitcoin core installed and synced with the network, you can just simply open the command console and type in and enter: setgenerate ...

If you are after bitcoins I wouldn't even spend time on CPU or GPU. It is now difficult with specialized hardware (butterfly labs, kncminer ... ). You can have a look at cloud mining (cexio) as well it is expensive and you have to have bitcoins already but you can buy and sell GH/s and you can actually make more from trading than mining.


4

This is largely what the sCrypt() based forks are intended for - both utilizing un-tapped CPU power on dedicated rigs or allowing casual miners to use their CPUs. At present, the difficulty on the Bitcoin network is so high that it's not even a question of profitability but capability - even with pooled mining, CPU mining is so slow that you may not actually ...

Normal people can mine but normal computers can't mine profitably. At least not any longer. Right now, in mid-October 2012, some people are doing OK mining on GPUs, particularly those who don't pay directly for electricity. However, roughly sometime around the end of November the mining proceeds get cut by half instantly -- something that happens every ...

The hashespersec field reports the speed of the built-in miner. It does not (and can't accurately) report the hashing power connected to it via the getwork or getblocktemplate interfaces.

The official bitcoin client from bitcoin.org has a CPU mining option. Add a file named bitcoin.conf to the bitcoin data directory, with the contents gen=1 https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File

I know this is an old question but recently I got a similar server. I've tested rpcminer, GUI Miner (Which is actually UFASoft miner). Personally the best I've found is CPUMiner. With a hash rate of about 75MH/s, it takes a bit of setting up as CPUMiner is normally used for Litecoin mining. CPUMiner gave me about 10%-20% more than the closest rival, which ...
