Mining- represents the production process, or more commonly for this area of ​​cryptographic coin mining. The essence of the digital currency mining process comes down to computers solving mathematical problems that select a hash code from a large list of numerical combinations. In order for this process to be carried out, a lot of computing power is required, so gaming video cards are most often used for this purpose.

Accordingly, if a trader follows changes and publications of the latest news in this industry, he observes the emergence of new gaming video cards. In general, cryptocurrency mining is gaining momentum in popularity, and many of those who are looking for a source of income are showing interest in cryptographic coins.

The topic of the article can help players understand the features of dual mining with ethereum and decred cryptocurrencies.

New items in the world of mining

For the AMD video adapter, a new miner from Claymor was recently presented. The basic distinguishing feature of this software from other existing ones is the ability to mine the most popular and profitable cryptographic coins Ethereum and Decred.

This news will make some changes in trading for people who specialize more in mining Ethereum and Decred on video cards from AMD.

Moreover, this miner provides clients with the mining of two altcoins, thereby opening up the best profitability indicators for cryptocurrency mining equipment.

The latest beta version of the dual (Ethereum plus Decree) miner for AMD GPU from Claymore will allow users to mine Ethereum, or work in dual mode, where two cryptocurrencies, Ethereum and Decree, are produced at once.

Of course, to mine Ether using other miners, the player needs AMD video cards with at least 2 GB of video memory.

When working with double mining, the player will receive a lower hashrate if we take mining only with Ethereum as an example.

When GPUs are fast, the less performance degradation will occur during mode 2 mining of two cryptocurrencies: ethereum and decred. The performance hit at the time of double mining for inexpensive and lower-performance video cards will be an order of magnitude more powerful.

Characteristic features of double mining

The nuances of working with this type of cryptocurrency mining boil down to the fact that it combines two different mining algorithms; they use GPU resources in a completely different way.

For example, Ethereum loads the video card memory quite heavily, and the GPU is weaker, then with the second cryptocurrency Decred the opposite is true.

Due to these characteristics, the player can get full-fledged Ether mining production, and at the same time slower Decred mining.

The creators of Claymore insist that the most profitable speed of mining Ether using its miner does not exceed three to five percent, due to the presence of a different base code for the Dagger-Hashimoto algorithm, used at the time of Ether mining.

OpenCL code is an optimized component in this development, which reduces the number of incorrect and old balls, plus increased performance due to increased load on the GPU.

But, at the same time, this process does not signal that mining will provide high hashrates; moreover, the miner will simply work less if we compare situations with software versions of Ethereum.

It should be noted that this cryptocurrency mining process is intended for dual mining only. There is no solo, that is, single production in this version of the program.

Please note that miners will only be working with pools running on Stratum to produce Ether. At the same time, only the basic GetWork mode is active for DEC mining.

A distinctive feature is that the miner does not support separate workers and the filer option; in the event of an emergency reconnection between several pools, the option specified in the default mode is simply absent.

If the player has set a goal for double mining from Claymore for AMD GPU, you need to remember that it is presented and available only in the form of binaries for Windows. The source code of the miner and versions for other OS operating systems are currently missing, or are simply not available to players.

This miner is free, so players use it most often for double mining, but note that the program has a small commission fee of one percent on Ethereum production. If dual mining works, then two percent of the commission is withdrawn. This money goes directly to the creators of the program.

Mining Decree is carried out with one hundred percent for the miner, there are no additional commission fees.

At this time, there is a version on the network designed for sixty-four-bit Windows, developed for modern AMD. Support is provided only by GPU series: 7xxx, 2xx and 3xx, memory from two gigabytes and above. Users should be aware that there is no support for NVidia graphics cards.

It should be noted that the miner is currently a beta version; unfortunately, there is no full release, so it is quite possible that players will encounter problems and errors when mining cryptocurrency.

This is one of the most pressing topics that are actively discussed on the Internet after the popularization of blockchain technology. Active users and enthusiasts continuously monitor the market and use various services that allow them to determine the most profitable cryptocurrency for mining at the moment. However, not all miners know that it is possible to mine two coins at once. This technology is called Dual Mining and is actively used with some algorithms. It is this interesting phenomenon that will be discussed in this material.

What is dual mining and how does it work?

In short, dual mining involves using different computer components to mine multiple currencies at the same time. This is possible due to the fact that different people use certain resources differently. For example, Ethash in Ethereum uses almost no GPU memory, and the algorithms of Siacoin and Decred coins work just the opposite, which allows you to use dual mode when mining these coins and thus increase profits.

There are also some that support dual. For example, Gridseed gc3355 allows you to mine Bitcoin and Ethereum simultaneously. It should be noted that new ASIC miners appear regularly and pose serious competition to classic ones. Most likely, the mining industry will soon completely pass into the hands of large industrial players, and home mining will remain only as an activity for crypto enthusiasts.

Dual mode often involves simultaneous mining of Ethereum, Ethereum Classic or Expanse and a second compatible currency. Their list is regularly updated with new projects, but new compatible algorithms do not appear so often.

Unfortunately, there are no such alternatives for the Equihash algorithm, which makes it impossible to mine the currencies ZCash (Zec), ZenCash (Zen) paired with the second, additional one. In addition, due to the recent emergence of ASIC miners for Equihash, home mining of these currencies is becoming much more difficult. The ZCash developers have already stated that counteracting ASIC miners is not a priority for them.

How to set up dual mining

Let's look at setting up dual mining using the ETH+DCR pair as an example. The first thing you need to do is register wallets for the selected cryptocurrencies. You can use official PC programs, mobile applications or special websites. Some cryptocurrency exchanges also support transfers of funds from mining pools. It is important not to confuse the addresses of Ethereum and Decred wallets when setting up the program.

If you don’t know, then you can use, for example, the Suprnova.cc service. This pool network supports many cryptocurrencies, and Decred with Ether is one of them. After a one-time registration on the site, you will have the opportunity to mine any currency there. You also do not need an additional wallet, since the coins are stored directly in your account and you can withdraw them to another address yourself at any time.

You can also recommend Dwarfpool pools with support for Ethereum or Nanopool with support for Ethereum and Siacoin, which is an alternative to Decred in dual mode. In general, anyone can use a pool, but these services have proven themselves well and have been operating on the market for several years.

Next comes the most important part - setting up the miner. We will use . This software can be considered the main one when working with dual mining mode. First you need to create *. .bat file in the program folder. Later, you can create a shortcut for it and place it in any place convenient for you, for example, on your desktop. So, open the file with regular notepad and specify the settings line in it. The first part will be responsible for the extraction of Ether, and the second - for the extraction of Decred.

The final line should look something like this:

EthDcrMiner64.exe -epool Ethereum pool address-ewal Ethereum wallet address-eworker name of the worker on the Ethereum pool-epsw Ethereum pool worker password-dpool Decred pool address-dwal Decred wallet address-dworker worker name on Decred pool-dpsw worker password on Decred pool-dcri 30

All values ​​are indicated without asterisks. Some pools do not require a worker or wallet to be specified, and the configuration line setting depends on the pool you select. The last value “-dcri” indicates the mining intensity of Decred. It is recommended to set this value from 30 to 45. When you try to increase the intensity, your Ethereum hash will begin to sag, and the temperature of the video card will exceed acceptable standards.

On the Internet you can find ready-made examples of bat files or even services that allow you to generate them based on the data you entered. The most important thing is to make sure that your wallet address or worker is indicated.

To start mining, you just need to launch the resulting Claymore batch file. The program will display in the console all data about the hashrate and temperature of the devices. In dual mode, the video card heats up more, so it would be wise to also specify in the settings the maximum permissible temperature, after reaching which the process will be interrupted. This will extend the life of the GPU.

You can also create several different .bat files with different sets of configurations or even to mine different currencies and switch between them if necessary.

As for overclocking a video card, the situation here is the same as with regular mining. An increase in power leads to a proportional increase in the hashrate of both currencies.

Is dual mining profitable?

The question of how profitable it is to mine two coins simultaneously in dual mining mode is actively discussed on thematic forums. Users note that despite the increased energy consumption of the dual, income still increases significantly. Some even write that the hashrate of each individual currency in this mode is higher than when mining separately. This is due to the architecture of the GPU chips, as the developer of the miner Claymore wrote about.

It should be noted that it is better to engage in dual mining on video cards that are under warranty. This is due to the fact that the wear and tear of the equipment in this mode is much greater and if the video card breaks down, the owner will suffer large losses instead of receiving benefits.

A special calculator will help you evaluate the profitability of dual mining. There are several similar services; consider one of the most popular - WhatToMine. To use it, you need to go to the WhatToMine website, find the drop-down menu at the top of the page called “ETH+” and select the desired pair.

The following are available there:

• ETH+DCR (Decred)
• ETH+SC (SiaCoin)
• ETH+LBC (LBRY Credits)
• ETH+PASC (Pascal Coin)
• ETH+PASL (Pascal Lite)
• ETH+MAX (MaxCoin)
• ETH+SMART (SmartCash)
• ETH+XVG (Verge)

Ethereum Classic or Expanse can also be used instead of Ethereum. Simply open the corresponding drop-down menus: “ETC+” and “ETH+”.

Unfortunately, in the dual calculator there is no way to simply specify the series of the video card, for example, ASUS Radeon RX 580. You must enter values ​​for both currencies. However, these values ​​can be taken from another section called “GPU”. There is a calculator for classic mining with the ability to select a GPU series and display its indicators in various currencies. You just need to select the series of your graphics card, be it ASUS dual-GTX1060-o3g, Palit Geforce GTX 1070 or dual-RX 580-o8g. But the 460 model is not supported, so if you have any ASUS AMD Radeon RX 460 dual OC, then it is better to look for information elsewhere.

It is recommended to compare current data from time to time; perhaps one of the coins will become more profitable in a dual. However, at the time of writing, all couples bring in approximately the same amount of money, and the difference is no more than one cent per hour.

Which coin will be more promising in dual?

The cryptocurrency market is known to be very unpredictable. The value of a particular currency can fall and rise significantly in just one day. The same applies to those currencies that are mined in conjunction with ether. You can choose the currency for dual using the above-mentioned calculator, but it should be noted that the income from all dual mode options is always approximately the same and rarely changes.

Another opportunity to decide on the choice of dual currency is to familiarize yourself with the technical analysis of the exchange rate from professionals. Some predictions sometimes come true. Moreover, you can make your own assumptions based on the graphs.

It is recommended to simply create several baht files with settings for different pairs and switch between them depending on the market situation. Alternatively, you can simply mine every couple of days and move on to the next one. This will help you diversify your portfolio, protect yourself from possible exchange rate crashes and earn more.

One of the most interesting options is cryptocurrency, which was actively growing in price at the end of 2017 and still causes discussion on cryptocurrency forums. Its main feature is anonymity, like that of , but using anonymization of client IP addresses.

Advantages and disadvantages of dual mining

Advantages

Flaws

1. Full use of farm power. The correct choice of cryptocurrency for dual mode will help you use the farm to its fullest and not lose useful power. This is perhaps the only way to get so much out of cryptocurrency mining equipment. 2. Good software. Fortunately, if you want to try the dual, you won't have to search for software for long. Claymore, a proven miner developer, offers a full-fledged tool for working in this direction. 3. No negative impact on Ether production. No matter how paradoxical it may seem, the Ether hashrate does not sag if the dual is configured correctly. This is also relevant for the second coin, for example, Siacoin or Decred. This is possible due to the fact that Ethereum mining uses almost no GPU memory, and the second currency compensates for this.

1. The need to make adjustments. Despite the fact that there are good software solutions for this area, you will still need certain knowledge to properly configure the miner. Some elements, such as intensity, significantly influence the entire process and must be specified precisely. 2. Increased wear and tear of equipment. Due to the full load on all components, the video card heats up and the cooling system operates at maximum speed. This negatively affects the service life of the device. Therefore, if your video card is not under warranty, then you have no choice but to remove dual mining from the list of directions you use. 3. Increased energy consumption. Electricity consumption also increases with the load on the video card, so slightly higher values ​​should be taken into account when assessing mining profitability than usual.

Conclusion

In conclusion, it should be said that dual mining is an interesting opportunity that allows you to use the farm’s resources to the fullest. Despite all the shortcomings, dual mining can be recommended for use by all those who want to increase the efficiency of cryptocurrency mining and earn more. Moreover, setting up this process is not at all complicated and is hardly too different from setting up a regular miner. Moreover, you can even set up a dual on the NiceHash miner, which has always been easy to use and friendly to beginners. We hope that this article helped you understand the topic under discussion, and you do not have any questions about what it is and how it works.

Mining profitability is one of the most important criteria for the modern Bitcoin community. This issue became most relevant in July 2016, when the reward was again halved (the reward is given to miners by the system for creating a new block). It was then that dual mining began to gain momentum.

The new tightening of regulations for miners and the complication of the mining process had a bad impact on the profits of major representatives in the cryptocurrency mining industry. Unfortunately, it was not the best time for amateur players, whose computing power was already barely enough to earn even an acceptable amount.

Today, supporters of the idea of ​​​​cryptocurrencies (miners) have several different ways to earn virtual money on a home farm. One of the most attractive options is dual mining of ether together with Decred or Siacoin. Earnings from these currencies are based on the use of similar methods and technologies through the use of standard intelligent information analysis mechanisms. In fact, to start mining, a miner only needs to slightly change the operating algorithm used.

Prospects for dual mining

Let's start with the fact that the idea of ​​earning several types of cryptocurrencies at once is not new at all. Thus, Bitcoin followers can start mining them simultaneously with electronic money, which is just beginning to appear on the market.

Members of the Ethereum community have set themselves the goal of organizing dual mining. When a person spends money on purchasing equipment for mining ethers, he does not necessarily have to limit his activities to mining only one type of virtual currency. The point is that double mining will be able to quickly return all the money invested in the business. Cryptocurrencies Decred and Siacoin are only traded on some exchanges. Their price is taken into account when determining the profitability of the operation.

It is noteworthy, but purchasing and installing cards for dual mining is not the most difficult task. The most suitable program for such purposes is considered to be a program called Claymore. The system supports the most famous and popular Windows software, as well as Linux.

After purchasing and setting up, the system automatically begins the process of currency mining (for example, eth dcr mining), while the dual miner does not have to carry out any additional actions.

It is worth noting that dual mining does not affect the quality of ether production in any way. The bottom line is that the process of receiving coins is carried out simultaneously, and the speed is the same for all types of virtual currencies. It turns out that with a process speed of 50 mh/s, the miner, in addition to ethers, will be able to receive the same amount of Decred or Siacoin.

The special thing about Claymore software is that it is capable of supporting multiple forms such as solo mining, Siacon, pool. If he is talking about Decred, then its extraction is carried out automatically using , solo work is impossible.

And also when calculating profits it is worth taking into account percentages. When mining ether, the user pays 1%, but the dual eth dcr miner is required to pay a double fee (2%). It turns out that almost all the production does not leave the developers’ accounts.

Claymore settings for dual mining

How to set up a dual miner? First, let's clarify that the official Ethereum miner does not work with Stratum; it only reads the HTTP protocol. This reduces returns due to delays.

To resolve this issue, proxies were deployed. It turns out that the official Ethereum client is connected to the proxy using a protocol available to it (HTTP - there are small delays for days). The proxy, in turn, is connected to the pool via Stratum, which is also characterized by low latency.

Today, most pools run on Stratum. The user will need a proxy adapter in order to ensure proper operation of the client. Of course, you can connect everything directly via HTTP. But then the loss of efficiency is inevitable due to the insignificant time it takes to search for an Ethereum block.

The advantage of Claymore is that it uses Stratum rather than HTTP. The user can directly connect everything to the pool, then it will function a little faster than a standard miner because it does not have to go through a proxy.

If you use equipment with 2 GB in the system, then it is recommended to set certain values:

How to set up dual mining? For equipment with multiple GPUs, you need to set the virtual memory volume to at least 16 Gb:

1. Open Start.
2. Find “computer”, right-click and select “Properties”.
3. On the left side, click "Advanced system settings."
4. In the “Advanced” - “performance” section you need to find “Settings”;
5. Open "Advanced", then go to the "Virtual Memory" menu and click "Change"

It is important to remember that the miner charges 1% fees for Ethereum mining and 2% for eth dcr mining. It turns out that the software takes from 30 to 80 seconds for the developer every hour.

DCR mining is carried out without paying for developer services. If you do not want to pay fees, you will have to not use this software.

Example of using a miner:

Among the popular problems:

• Weak hardware (or old-style cards). For example, from series 7 xxx/270/270X cannot work in dual mining mode correctly. And Ethereum mining is 10–15% slower;
• Some cards lose 1-3% in performance when mining currency.

The developer promises to fix these problems in the near future. Mining multiple virtual currencies allows you to increase your profits, which is especially useful for small farms.

Experts draw attention to the disappointing official statistics: 2018 can no longer be called the most successful year for the crypto market. It is slowly but surely losing its position among investors. In this context, conventional mining becomes an extremely dubious way to generate income. In the best case, it will be possible to cover losses with its help, but that is not what they are doing it for. Dual mining allowed us to literally breathe new life into old technology. It does not require any excessive additional investments, but when used correctly it guarantees increase income. There are several variations of it, the main ones being dual mining of Zcash and Ethereum. Mining work is carried out through the Claymore program.

What is Dual Mining

To understand what Dual Mining is, you should first find out in general. But advanced users are probably already in the know, but even they may have no idea about “double” mining of crypto-resources, although the principle is the same.

The point of the process is that with its help it is possible to simultaneously increase the number of coins of two different types. In this case, the idle computing resources of your equipment turn out to be involved - that is, a certain hidden reserve, that very “second wind” that opens for athletes before the finish line.

However, in reality everything is not so simple; not all cryptocurrencies are compatible in terms of parallel mining, so you should carefully select the most promising pairs. To do this, special settings for dual mining are set when directly launching the program.

Processors for dual mining

For dual mining, both types of processors are used: GPU and CPU. The Claymore program is compatible with most types of modern video cards, but for greater efficiency it is worth studying the assembly issue in advance.

• Dual mining technology does not involve compaction, but a kind of mirroring, cloning of computing processes inside a PC.
• Any video card is a huge number of block chains-algorithms, which are responsible for obtaining mathematical data that fits certain conditions.
• If the values ​​match, a specific block is activated.

In one unit of time, blocks are not used all at once, which allows the process of double mining. In this case, each algorithm will be responsible for its own task, and their intersection is impossible.

Dual Ethereum mining

After choosing one of the Dual Mining options, for example, based on the Equibash algorithm, you will no longer be able to use the second one. But also in within one scheme you can make pairs of 4-5 available cryptocurrencies. So, for the Ethash algorithm this is Ethereum (ETH), its classic version (ETC), Decree (DCR), Verge (XVG) and some others. The full list can be viewed in the program settings. Preliminary calculations using an online calculator, which can be found on many thematic resources, will help you decide which of them is more profitable.

Dual mining of Ethereum is carried out using the Claymore’s Dual Ethereum Miner subroutine. It is designed for a GPU processor and an AMD or Nvidia video card. The Dagger Hashimoto algorithm is used to extract resources. The dual nature of the process allows you to replenish the supply of coins at the usual speed, with only an insignificant loss of time. The program is simple and intuitive clear interface, which even not the most advanced participants in the crypto market can understand without any problems, especially since its Russian-language version is available. And those who are already well versed in the technology have the opportunity to experiment with a huge range of settings.
