This site will help you to compare all kind of hardware device for mining cryptocurrency like Bitcoin, Ethereum or Monero. Block reward is fixed at 0 ETH and future block reward reductions are not taken into account. The average block time used in the calculation is 0 seconds. The word mining originates in the context of the gold analogy for crypto currencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume is through mining. Ethereum, like all blockchain technologies, uses an incentive-driven model of security. Consensus is based on choosing the block with the highest total difficulty.

Miners produce blocks which the others check for validity. The Ethereum blockchain is in many ways similar to the Bitcoin blockchain, although it does have some differences. As dictated by the protocol, the difficulty dynamically adjusts in such a way that on average one block is produced by the entire network every 15 seconds. We say that the network produces a blockchain with a 15 second block time.

Ethash PoW is memory hard, making it ASIC resistant. Memory hardness is achieved with a proof of work algorithm that requires choosing subsets of a fixed resource dependent on the nonce and block header. As a special case, when you start up your node from scratch, mining will only start once the DAG is built for the current epoch. All the gas consumed by the execution of all the transactions in the block submitted by the winning miner is paid by the senders of each transaction. The gas cost incurred is credited to the miner’s account as part of the consensus protocol. Over time, it is expected these will dwarf the static block reward.


A maximum of 2 uncles are allowed per block. Mining success depends on the set block difficulty. Block difficulty dynamically adjusts each block in order to regulate the network hashing power to produce a 12 second blocktime. Your chances of finding a block therefore follows from your hashrate relative to difficulty. The DAG takes a long time to generate.

If clients only generate it on demand, you may see a long wait at each epoch transition before the first block of the new epoch is found. DAG generation and maintains two DAGs at a time for smooth epoch transitions. Automatic DAG generation is turned on and off when mining is controlled from the console. Note that clients share a DAG resource, so if you are running multiple instances of any client, make sure automatic dag generation is switched off in all but one instance.

DAG so that it can shared between different client implementations as well as multiple running instances. It is designed to hash a fast verifiability time within a slow CPU-only environment, yet provide vast speed-ups for mining when provided with a large amount of memory with high-bandwidth. The large memory requirements mean that large-scale miners get comparatively little super-linear benefit. The high bandwidth requirement means that a speed-up from piling on many super-fast processing units sharing the same memory gives little benefit over a single unit.

Pretty good

Communication between the external mining application and the Ethereum daemon for work provision and submission happens through the JSON-RPC API. These are formally documented on the JSON-RPC API wiki article under miner. In order to mine you need a fully synced Ethereum client that is enabled for mining and at least one ethereum account. This account is used to send the mining rewards to and is often referred to as coinbase or etherbase. Ensure your blockchain is fully synchronised with the main chain before starting to mine, otherwise you will not be mining on the main chain. This is no longer profitable, since GPU miners are roughly two orders of magnitude more efficient. You can also start and stop CPU mining at runtime using the console.

This etherbase defaults to your primary account. Note that your etherbase does not need to be an address of a local account, just an existing one. By convention this is interpreted as a unicode string, so you can set your short vanity tag. Note that it will happen often that you find a block yet it never makes it to the canonical chain.

This means when you locally include your mined block, the current state will show the mining reward credited to your account, however, after a while, the better chain is discovered and we switch to a chain in which your block is not included and therefore no mining reward is credited. The algorithm is memory hard and in order to fit the DAG into memory, it needs 1-2GB of RAM on each GPU. ASICs and FPGAs are relatively inefficient and therefore discouraged. For this quick guide, you’ll need Ubuntu 14. 04 and the fglrx graphics drivers.

Unfortunately, for some of you this will not work due to a known bug in Ubuntu 14. 02 preventing you from switching to the proprietary graphics drivers required to GPU mine. Whatever you do, if you are on 14. 02 do not alter the drivers or the drivers configuration once set. If you accidentally alter their configuration, you’ll need to de-install the drivers, reboot, reinstall the drivers and reboot. Ethminer will find geth on any port.

Setting the ports is necessary if you want several instances mining on the same computer, although this is somewhat pointless. If you are testing on a private chain, we recommend you use CPU mining instead. CPU mining on TOP of GPU mining. Let’s not get spammed by messages. Set the coinbase, where the mining rewards will go to. The above address is just an example.

This argument is really important, make sure to not make a mistake in your wallet address or you will receive no ether payout. Request a high amount of peers. Helps with finding peers in the beginning. Mining with multiple GPUs and eth is very similar to mining with geth and multiple GPUs. Additionally we removed the mining related arguments since ethminer will now do the mining for us.

OpenCL can detect, with also some additional information per device. DAG of the next epoch ahead of time. Although this is not recommended since you’ll have a mining interruption every time when there’s an epoch transition. Mining power tends to scale with memory bandwidth. Our implementation is written in OpenCL, which is typically supported better by AMD GPUs over NVidia. Empirical evidence confirms that AMD GPUs offer a better mining performance in terms of price than their NVidia counterparts. To start mining on Windows, first download the geth windows binary.

Use cd to navigate to the location of the Geth data folder. As soon as you enter this, the Ethereum blockchain will start downloading. Now make sure geth has finished syncing the blockchain. At this point some problems may appear. GPU does not have enough memory to mine ether. Mining pools are cooperatives that aim to smooth out expected revenue by pooling the mining power of participating miners. The mining pool submits blocks with proof of work from a central account and redistributes the reward to participants in proportion to their contributed mining power.

Most mining pools involve third party, central components which means they are not trustless. In other words, pool operators can run away with your earnings. There are a number of trustless, decentralised pools with open source codebase. Mining pools only outsource proof of work calculation, they do not validate blocks or run the VM to check state transitions brought about by executing the transactions.

Phase velocity minimum[edit]

Mining and cryptocurrency are dirty words to many of my readers. Use your existing gaming PC to make some extra Bitcoin, or extra cash. When I stopped mining for crypto coins back in 2013, getting a client up and running was a challenge. Basic knowledge of Linux and terminal commands were requirements. Instead, you’re automatically selling your PC’s hashing power to other miners who are mining those coins, effectively contributing to a pool’s combined power.

Users can see higher hashrates and thus higher profits when doing things like flashing their GPU’s BIOS, using command-line based clients, overclocking and undervolting, and installing alternate drivers like AMD’s Blockchain Driver. How Much Can Your GPU Make? Wh electricity cost, meaning you’re seeing profits after paying for the power consumption of that GPU. Your mileage may vary is an understatement here. For my part, I can confirm the accuracy of the Radeon RX 580 and Nvidia GTX 1060 earnings.

For those of you rocking something like a 1080? I included AMD’s higher-end 7000 series cards here because they’re not too shabby and tons of people still use them. Obviously these profit numbers will fluctuate for you, especially since you’re probably going to use your rig and not dedicate it solely to mining. Better to have it collecting Bitcoin than dust.

Just remember that mining could decrease the life expectancy of your GPU. If you try it out, let me know how it’s going for you! Extra dirty to people looking to build their own gaming PC in a retail landscape that’s seen the prices of graphics cards from AMD and Nvidia inflate to atrocious levels. Before I get ahead of myself, let me lay down a few important comments. Your hashrate — or the power at which your GPU can mine — is always being directed to what the most popular crypto coin is.

Before your first launch, the software will benchmark your hardware’s hashrates for a variety of algorithms that correspond with those coins. All of the GPUs listed below were tested in the company’s labs, and are pulled from actual profit numbers from users, not estimated ones. Even a GTX 1060 3GB is a decent little miner while being incredibly power efficient. As for AMD’s latest Vega cards, they may chew through power, but they also spin a decent profit after the electricity bill gets paid. At the very least, I believe the majority of people could be profiting enough to buy a new game every month. Reach out to me on Twitter and Facebook. Welcome back to a series of guides on cryptocurrency and mining!

In Part 1 we dove into the basics of blockchain technology and what purpose mining actually serves. Then we’ll jump into some advanced tuning to maximize performance and profits. Hashing power is the measure of mining performance your GPU or CPU has with any given coin algorithm. PC’s hashrate to buyers actually mining a certain coin. Since the cryptocurrency market is constantly fluctuating, this is a helpful feature. The decision is yours to make.

I used it for about 2 months and enjoyed the experience, but was ultimately compelled to enter more advanced waters. As I said earlier, it is a great doorway into mining and I do recommend it for beginners. Grab a beverage and let’s do this. Doing so will automatically create a service-side Bitcoin wallet for you, which Nicehash automatically deposits into. Download the one appropriate for your software here.

So let’s split up right here to walk through both Nvidia and AMD setups. 0 for Nvidia, hit step 2b. AMD cards, skip down to step 2c! Go ahead and launch the installation file and acknowledge the license agreement and read the risk acknowledgement.

I know we normally gloss over this stuff, but this one matters. If you’re content with your case’s airflow and your GPU thermals, then let’s keep going. This is OK, and Windows Defender should not flag any of it as a virus threat. If it does, I can assure you it’s not. Ok, welcome back Nvidia and AMD users!

This part is also slightly different for each of you, but simple enough that we’ll contain it to the same paragraph. Your Mining and BTC Deposit Address. However, do not mine from other locations into this wallet. Fire Strike or the various built-in game benchmarks you’ve used, but if you do enjoy tweaking your GPU you might get some enjoyment out of this down the road. It determines which ones are best suited for your graphics card. Since it knows the value of any given coin in near real-time, and how your GPU performs mining that coin’s algorithm, doing this is a critical step. When you come back, the benchmark should be done and you’ll be mining away.
