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 ...

Please check this question first: How much Bitcoin will I mine right now with hardware X? Before you go through all this work, it is important to know what to expect from your hardware. There are two options: solo mining or pool mining. Unless you have a lot of computing power (several ASICs), you should probably mine at a pool. So the first thing to do ...

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 ...

You can use Adblock Plus to block the miner script. In this case it would be: http://www.bitcoinplus.com/js/miner.js

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,...

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 ...

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,...

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 ...

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 ...

First report about mining botnet was made at the end of June, and it evolved rapidly from CPU to GPU mining. But there is no consensus about what kind of harm it will do to Bitcoin, because from the bitcoin network point of view, infected computers run legitimate mining that supports network operation. 17 Jun 2011 - Symantec suggested that it would be ...

If you're fluent in Python, there is a reference RPC miner, written by one of bitcoin's developers: https://github.com/jgarzik/pyminer

I'm in a mining pool, using several multi-core servers and generating about 7-10Mhashes/second. It has yielded me currently about $0.01 dollars in the last 36 hours. I do not pay for electricity. I made a penny. It's not that exciting. :) There are GPUs that can accumulate my MHash rate that I create across several CPUs, without even getting warm. So my ...

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 ...

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.

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

You would need some kind of browser plug-in that monitors the CPU consumption of JavaScript and alerts you if you see excessive usage for an extended period of time.

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 ;)

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 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 ...

CPU mining for Bitcoins is almost never worthwhile since the advent of GPU mining. If your EC2 instances are free you're welcome to try but there's a better alternative. A decent CPU won't get you but 3-5 MH/s of Bitcoin mining power, which at current difficulty and exchange rates will net you about 0.0046 BTC per day (worth about a penny at current rates). ...

So let me summarize all the other answers: Krad Miner used to be the first WebCL miner, but due to DDOS attacks it was not working for awhile. Later it was bought and open sourced as Tumen Miner. BitMinter allows you to mine on their pool with OpenCL miner through Java Webstart. www.coined.com has undefined status, WOT reports it as an abusive site. ...

There were a number of news articles in September 2011 about the rootkit TDL4 using the Ufasoft GPU miner to mine bitcoins.

While not directly a WebCL miner there is a miner which uses OpenCL via Java Webstart so is accessible to any internet user with Java installed and apropriate hardware. http://www.BitMinter.com The site is both a pool and a custom java miner. The pool can be used with other miners however the BitMinter miner works only with the BitMinter pool.
