The server pool is intended for preliminary creation of virtual servers on the handler with their subsequent issuance when ordering services. Thus, a significant reduction in order processing time is achieved. This feature is available from BILLmanager 5.85

Activate the server pool for the processing module

When the pool is active, BILLmanager 5 automatically creates servers on processing modules with the "Use pool" option enabled.
To use the pool, you need to create a special account to which servers from the pool will be linked. This is a normal client, with the exception that the servers attached to it are considered to be in the pool and are given away when ordering services other users.

Pool account automatically appointed 100% discount when connected to the processing module.

For the correct functioning of the pool, it is necessary that the account be included in a group with rights "Allow removal of services" and "Ignore number of services per account". This setting must be done by yourself.

You can enable the server pool in the processing module settings, both when creating it and when editing it.
To enable the pool, check the "Use pool" option and in the list that appears, specify the previously created client under which servers will be created in the pool.

Processing module settings

Field list:

• Use Pool- if the option is active, then virtual servers are automatically created in the pool;
• Client- the account under which the servers are ordered to the pool;
• OS Templates- list of operating system templates for which servers will be created regardless of statistics;
• Max. pool time- maximum time spent by the server in the pool, in months; upon reaching this time, the servers are automatically deleted;
• Calculate statistics for- period in days for which statistics of ordered servers are calculated. Based on the statistics, the number of servers created in the pool is calculated;
• Ordered for the period (0< VDS <= 3) - the number of servers created in the pool, if according to statistics for the specified period, customers purchased from 1 to 3 virtual servers;
• Ordered for the period (3< VDS <= 6) - the number of servers created in the pool, if according to statistics for the specified period, customers purchased from 4 to 6 virtual servers;
• Ordered for the period (6< VDS <= 10) - the number of servers created in the pool, if according to statistics for the specified period, customers purchased from 7 to 10 virtual servers;
• Ordered for the period (10< VDS <= 15) - the number of servers created in the pool, if according to statistics for the specified period, customers purchased from 11 to 15 virtual servers;
• Booked for the period (VDS > 15)- the number of servers created in the pool, if, according to statistics, more than 15 virtual servers were purchased by customers for the specified period.

How a server pool works

A job is created for the pool in the cron:

*/3 * * * * /usr/local/mgr5/sbin/mgrctl -m billmgr itempool.process.cron

When the itempool.process.cron function is running, the following operations are performed:

1. statistics are calculated according to the specified settings
2. servers are created in a pool
3. removing old servers

Statistics are stored in the database in a table itempoolstat. The calculation of statistics is slightly different depending on the version used. VMmanager:

• for VMmanager KVM operating system and tariff plan are taken into account
• for VMmanager OVZ operating system only

When creating servers in a pool for VMmanager OVZ tariff plan is selected automatically - the first tariff plan connected to the processor is taken in accordance with the priority (field "Sorting" in the list of tariff plans - the lower the value, the higher the priority).

When creating servers in a pool, there is a limit of one operation on one handler at a time. The same restriction applies when deleting old unclaimed servers.

Issuing servers from the pool

When processing an order, it is sorted through the servers that match the parameters in the pool (if an attempt to issue the first server is unsuccessful, the second one is selected, etc.).

For each server it runs:

• copying parameters and IP addresses from the service in the pool to the service ordered by the client
• removal from the database of information about the service in the pool
• server domain name change
• for VMmanager KVM, if the operating system is not Windows, the script is executed to change the hostname (via ssh)
• if the customer selected a recipe when ordering, it is launched
• run the setparam operation to apply the current settings

If a suitable server was not found, or all attempts to issue from the pool failed, the standard process of creating a virtual server starts.

When the "Use pool" option is disabled in the handler settings, the virtual servers already created in the pool are not deleted, but are issued when processing customer orders until they run out, or until they become obsolete and are deleted by the crown.

How does a mining pool work?

So, as we have already found out, you, being a member of the pool, provide the server with the computing power of your equipment and in return receive your part of the mined coins.

The contribution of each participant to the closing of the block is estimated in a share (from the English "share" - share, part). The share is part of the work of finding a solution to the hash function for signing the block, which is issued by the pool to the miner. The task of the mining pool is to collect the balls from the miners and check their validity. When the pool server sees that the ball satisfies the current values ​​of the complexity of the network algorithm, it claims to have found a block. For closing the block, the mining pool receives a reward, which it subsequently must distribute among the miners participating in the pool. There are several approaches to reward distribution:

• PROP or proportional approach is the simplest way to distribute rewards for finding a block. In accordance with this approach, the reward is divided proportionally to the share sent by each member of the mining pool. Payment of remuneration is carried out only upon signing the block.
• PPLNS (Pay Per Last N Shares) is considered to be the most efficient way to distribute rewards for signing a block. Payments are made not upon finding a block, but for “shifts” (a certain number of time intervals).
• PPS (Pay Per Share) - is considered the most optimal option for distributing rewards for finding a block from the point of view of a pool member. In this case, the miner-participant of the pool receives a certain reward for each share sent by him. This payout is calculated by dividing the block reward by the difficulty of the network. For a mining pool, this option is not the most preferable, because the risks with this payment option are much higher (therefore, pools that use this approach charge a large fee).

It is also worth noting that the server owner takes a commission from the reward that the miners participating in the mining pool receive for closing the block. As a rule, commission costs range from 0.1 to 5 percent. In addition, some mining pools often resort to some tricks to earn more money. For example, sometimes some unscrupulous servers underestimate the spent computing power of miners, which allows them to earn an additional 10% of the reward amount. Of course, not all joint mining pools resort to this practice; there are also honest, profitable pools that value their name. In addition, there are cryptocurrency mining pools that claim to have no fees (such as the zen mining pool). Be careful, as a rule, such services charge hidden fees.

How to choose a mining pool

We figured out the essence, but then a completely natural question arises: which pool to choose? For beginners, choosing the best mining pool is not an easy task. But we will help you navigate all this variety of pools, each of which is trying to assure potential customers that their server is the most profitable pool.

In general, it is worth noting that the main thing that interests us in the mining pool is the opportunity to earn. Accordingly, the choice of pool should be based precisely on this criterion. There are several parameters, the analysis of which will allow you to form a more or less accurate idea of ​​the “quality” of a mining pool:

• pool power. The higher the processing power of the pool you choose, the more likely it will be the first to find a block. In the context of making a profit, this is an incredibly important issue, because if the server cannot effectively close blocks, then it will not be able to offer you a normal profit, which means that you will simply be wasting your time and money. New mining pools just can’t boast of decent capacities, so you should refuse such options.
• approach to the distribution of remuneration among the miners participating in the mining pool. We talked about this in the previous paragraph of our article. You will need to find out exactly which approach is used by a particular mining pool. You must choose the option that suits you, so as not to miscalculate the profitability of your mining. For example, if the mining pool you are interested in adheres to a system of proportional reward sharing, and you cannot make a significant contribution to the development of the block, then you, accordingly, will not be able to receive a normal profit.
• payment method. It can be like withdrawing mined coins to a cryptocurrency wallet or withdrawing funds to a card; withdrawal currencies may also differ. There are a lot of options, you need to choose the one that suits you specifically.
• commission costs. Be sure to study this issue, because the profitability of mining will also depend on it. It is not necessary to chase the minimum commissions; the main thing is that, subject to the payment of commission costs, you can still reach a decent profit.
• your original data. This is, of course, about your cryptocurrency mining equipment and your electricity tariff. Theoretically, you can mine in the pool , or , but in practice, not all options will be profitable. For example, mining on the central processor is generally the most low-profit option, and subject to high electricity tariffs, it is generally unprofitable. In any case, mining on old, low-performance equipment will not be able to bring you good profits, therefore, you should make sure that your mining equipment produces a decent hash rate. Also pay attention to the cost of electricity in your region or country, because your mining costs and, as a result, your profit will depend on this price. Check the electricity tariffs offered by your supplier, there may be discounted tariffs that you can take advantage of.

It will not be superfluous to also look for information about the mining pools that you are interested in on the network. Read forums, reviews and reviews, see the rating of the best mining pools. The network also provides independent pool statistics (for example, on the blockchain.info website).

In general, there is no single answer on which mining pool to choose. For each miner there is an optimal variant. Accordingly, you should evaluate mining pools based on your own goals and wishes.

How to set up a mining pool

Now that you have already decided on the ideal mining pool for you, you can proceed to the next step - setting up your mining pool. Setting up a mining pool is quite simple and fast, even a beginner can easily cope with such a task.

Of course, before you start working in a mining pool, you need to create your personal account. We will consider this process using the example of bitcoin mining in the SlushPool mining pool (on other platforms, the setup procedure may be slightly different, but not critical; the essence is the same).

To do this, you will need to go to the site and find the "Register here" button in the upper right corner of the page. You will need to fill out a short registration form in which you must provide your username, email address, password, and agree to the platform's rules. You will receive an activation link by email, clicking on which will complete the registration process.

Now that you have your own account, you must set up your account, edit or add new workers, add the address of the cryptocurrency wallet to which your reward will be paid, set up two-factor authentication (optional, for greater reliability and security), etc. .d.

In addition, it is worth noting that the platform has an online calculator that allows you to calculate how much profit you can get if you mine in this mining pool using your mining equipment. You just need to enter the hashrate of your device and the calculator will calculate the approximate reward that you can receive, and you will only have to take into account your electricity costs.

Next, you will need to connect your mining equipment (in our particular case, an ASIC miner) to a mining pool. If you are using a standalone ASIC miner with the Stratum protocol, then installing it is not difficult, since such mining equipment usually comes with some kind of user interface and you only need to specify the address of the server(s) (url(s)) , username and password:

• URL: stratum+tcp://stratum.slushpool.com:3333
• userID: userName
• Password: whatever

You will need to enter your user ID and worker name. The password can be a random word, since in this case security issues are not affected. If someone tries to connect to the server using your account, they will mine in your favor.

If you are using an ASIC miner connected to your personal computer, then you will need to download and install the one you intend to mine. (NOTE: You will need the miner software anyway if you are going to mine on the CPU or GPU!)

As a rule, the official website of the mining pool you have chosen lists the mining software packages that this particular platform supports. Links are also posted there, following which will allow you to download the miner program. For example, SlushPool offers you to download either cgminer or BFGminer, which only work with ASIC miners (in principle, mining bitcoins on a non-ASIC miner does not make sense). You download the mining program and unpack it to a convenient place on your personal computer, and then install it (the installation guide will also be presented on the official website of the mining pool or you can find it on the net). You will need to tell the miner the address of the server(s) (url(s)), username and password. To do this, you will need to create a .bat file. This can be done very simply: create a new document in the Notepad text editor, write in it something like the following command - ./cgminer --userpass userID.workerID:Any password --url stratum+tcp://stratum.slushpool.com:3333- and save this file in bat format.

Next, if you haven't already, of course, you'll need to set up a payout address. Please note that a mining pool is not a wallet, so it is not possible to create your payout address on the pool website. However, there are many wallet providers (see our articles and). You can easily create a wallet for yourself or use the exchange's cryptocurrency wallet. Go to the "Payouts" tab and enter your wallet address there.

On this, as a rule, the mining setup in the pool is completed and you can proceed directly to the extraction of your chosen cryptocurrency.

How to create your own mining pool

Mining in a pool is a rather tempting and promising idea for making money. But the fact that a part (albeit small) of honestly earned money must be given to the owner of the server does not please many. Such miners are interested in whether it is possible to create a mining pool with their own hands. From the news, many have heard that bitcoin enthusiasts from Russia have created a mining pool, but it is not known if it is so easy to do and what the future holds for these Russian mining pools. Let's see if it's really possible to make your own pool.

Theoretically, it is quite possible to create your own cryptocurrency mining pool, but for this you will need certain knowledge and skills, because we are talking about writing software. Of course, now on the network (for example, on the Github website) you can find the mining pool server software, but its performance and reliability are questionable.

In any case, if you absolutely do not understand this issue, but still want to organize such a business, then it is better to hire developers who will make a pool for you, which means that we are talking about quite a big cash investment. But also take into account the fact that in order for you to make money on your mining pool, you will need good computing power, which means that your pool must be popular with miners. And gaining the trust of miners and promoting your own pool is not so easy! So, if you are not ready for this option, then it is still better for you to refuse it.

Pools VS Cloud Mining

Currently, another popular and profitable option for making money on the extraction of digital currencies is. In fact, cloud mining is the same mining in a pool, but without using your own equipment for mining cryptocurrencies. In this case, the cloud mining service offers you to rent your computing power for a certain fee (in other words, buy a hashrate). Companies that provide cloud mining services are the most powerful data centers with mining farms located in countries where electricity tariffs are incredibly low or there is access to green energy (energy obtained from alternative sources). In addition to paying for power on some platforms, you will also need to pay a commission (this is how some services cover their mining costs, in particular electricity costs).

A natural question arises: is it better to mine cryptocurrencies in a mining pool or use the services of a cloud mining service? Of course, if you do not have a powerful one, then it is better for you to opt for the cloud mining option, because the purchase of computing power will cost you several times cheaper than the purchase of top-end equipment. In addition, for a beginner, this option is the most convenient, since you will not need to set up mining equipment and software, control the operation of this equipment, pay electricity bills, etc. Also, it is worth noting that the cloud mining option is ideal for those who live in regions or countries where electricity tariffs bite, because in their case mining in the pool can easily be unprofitable. If you have good mining equipment, then perhaps you should still choose the option of mining in a pool, because in this case it is not worth spending money on renting a hashrate.

Accordingly, there is simply no single answer to the question of which is better: pool mining or cloud mining. The choice is solely yours. In any case, to get a more accurate answer to the question posed, you should resort to the help of a mining payback calculator. On the official websites of mining pools or cloud mining services, as a rule, there are special calculators that will help you roughly calculate the profit that you can make. You can also make calculations manually, for this you will need to subtract all mining costs from potential income.

Conclusion

In general, mining pools are a great option for passive income. Pool mining allows you to greatly increase your chances of success, which is especially true at the present time, when the competition in the mining industry is incredibly serious, and the complexity of the network is constantly growing. Even solo mining on powerful hardware may not give the desired results, especially when it comes to mining top cryptocurrencies.

The main thing in this context is to choose the right mining pool, because an insufficiently powerful pool is unlikely to be the first to find a block, which means you will wait a very long time for your profit. Accordingly, before choosing one or another platform, you should thoroughly study all the options and only then make any decisions. This article should just guide you in this matter and help you make the right choice.

Alexey Russkikh

The era of solo mining is long gone. The ratio of computing power and complexity of networks does not allow receiving a reward for signing a block. Today, the only way to mine cryptocurrency is to join mining pools. However, many miners fail when choosing a pool due to a lack of understanding of the principles of operation, specifics, differences and other features of mining pools.

In this article, we will look at everything related to mining pools: from their differences to choosing the best servers for specific cryptocurrencies.

Mining pool definition

A mining pool is a kind of server whose main task is to divide computational tasks into many subtasks. The latter are distributed among all participants that are connected to the pool. Initially, mining existed, their computing power was enough for independent cryptocurrency mining.

As the complexity of the network grew from attracting new participants, the mining of “coins” switched to video cards. Mining on processors was a thing of the past due to the minimum profitability (and later, the complete lack of profit).

Subsequently, the process of increasing the complexity of mining led to the fact that without combining the capacities, miners could no longer mine cryptocurrency. It is important to consider that the mining pool is not a completely collective mining with an even distribution. It is rather a division of tasks, where each participant receives a profit, depending on the effort (capacity) invested.

Principle of operation

The contribution is evaluated by the concept of "ball" (from the English share), which is part of the computational hash function for signing the block. The task of the server is not only to distribute tasks, but also to check their validity. When the “ball” corresponds to the complexity values ​​necessary for signing the block, the operation is confirmed.

The reward received by the pool is distributed to all miners, depending on the number of valid "shares" transferred (depends on the method of reward in a particular pool). Moreover, the signatory of the "ball" block does not affect the final distribution of the reward in any way.

Each such server is a full-fledged business that “lives” on commissions charged from users. Mining pools can underestimate the overall computing performance to generate additional profit from "unaccounted for power" (the so-called "hidden fee"), but such servers instantly fall into negative ratings and blacklists, losing all participants.

In technical terms, the device of the mining pool cannot be called complicated. It is a dedicated server that distributes tasks. Moreover, the pool does not require complex configuration (if you have ready-made templates). However, the key aspect is the involvement of participants, which is based on:

• Powerful advertising.
• Mining pool reputation.
• Security.
• Favorable conditions for participants (low commission and other privileges).

You should also remember the “51% rule”, which is a direct threat to centralization and allows you to attack any cryptocurrency. Upon reaching this mark, the pool should potentially announce its liquidation, if the collection of high capacities does not pursue specific goals.

Mining types and reward methods

In the field of cryptocurrency mining, there are three types of mining:

1. Solo.
2. Collective (in Pool).
3. Cloudy.

The latter stands out noticeably from the rest, since it does not require the presence of equipment, it is often categorized as an investment, not a “digging”. Solo mining is almost completely a thing of the past. This is due to the growing complexity of networks and the demand for digital money mining.

New “coins” rely on solo mining, but as they develop and attract participants, “loners” will be quickly crowded out. An example is Pirl coin mining solo without a pool. Therefore, collective mining, with the combination of capacities, is the only way to compete in the field of cryptocurrency mining.

One of the key factors when choosing a server is the reward method that is used on a particular resource. It can affect the final earnings and both increase and decrease the potential income. There are more than 20 ways to reward, although PPS and PPLNS are considered the most popular and massive. The simplest PROP method is becoming less and less popular, gradually becoming a thing of the past.

PPS or Pay Per Share– for participants, this type of remuneration is considered the most promising. When a block is found, each participant receives income for each sent "ball". The amount is calculated for the user by dividing the reward by the complexity of the network. Even though this distribution principle is the most profitable for miners, it is more risky for pool owners, which usually leads to higher commissions.

PPLNS—Pay Per Last N Shares- the method is considered one of the most profitable and does not include payments for each "ball". The accrual is carried out not for the search for a block, but for the so-called "shifts", which represent certain time intervals. The method is in many ways similar to PROP, but differs in a “slow start” when accruing remuneration.

That is, the calculated power indicator will increase to the maximum gradually (only after reaching the peak value, payments will be full). But even when disconnected from the mining pool, payments will occur until the calculated power drops to zero.

In addition to the three above methods of remuneration, there are the following types:

Solo	CPPSRB	PPSW
PPS+	Geometric	POT
SMPPS	DGM	BPM
ESMPPS	FPPS	Eligius
puddinpop	HBPPS	Triplemining
RSMPPS	RBPPS	Score

How to choose a good mining pool?

Choosing a mining pool for beginners can be a daunting task, especially with a huge variety of servers. First of all, the pool must be financially profitable, this is the primary and only important criterion. The following parameters will help you choose the most profitable, safe and stable option.

Hashrate

The power of a particular pool directly affects its potential in finding new blocks, and hence the income of participants. It is for this reason that the resources created among the first are the most popular.

Any new servers, despite their features, cannot attract such a large number of participants, which means they will lose in terms of power and efficiency in finding blocks.

Commission amount

This criterion cannot be called defining, but it also contributes to the income received from mining. Before choosing a server, make at least a superficial comparison of different pools in terms of commission. In the long run, this may affect your earnings.

Reward system

An important indicator that needs to be correlated with own capacities in order to extract the most favorable conditions. For example, with a proportional distribution of profits, in the case of low capacity, the level of income will be unusually low due to an insignificant contribution.

Therefore, the choice of a reward system will be important if it meets the conditions (for asics, or large centers, it is different and is selected individually).

Location

An important parameter. In this regard, there is an opinion that it is best to choose servers that are located as close as possible to the equipment. This will ensure a stable connection and minimal ping.

The immediate geographical location is of secondary importance. To select the best connection, use the "ping" command with the server address.

TOP-5 pools for Bitcoin

Consider the largest bitcoin mining pools that provide the best conditions for cryptocurrency mining.

btc.com

The undisputed leader, which, according to statistics, occupies a huge part of the total network hashrate (16.8% on a monthly basis and 18.3% in annual monitoring). Its peculiarity lies in the low commission (1.5%) and the use of a modified and unique reward system. For this, a more advanced version of PPS is used, which implies a full fee for "balls" (FPPS). Specializing in Algorithm.

Opened in 2016, although the brand was known before, thanks to the creation of a popular wallet. The main servers are located in China and Germany, and the company also plans to expand to Canada and Switzerland.

Another largest pool that stands out thanks to the functional panel and the ability to choose the reward method. It is part of the Bitmain concern, a company that produces ASICs. According to annual statistics, it is in second place, occupying 13.1% of the total capacity.

Low payouts are considered a minus, and the use of a peer-to-peer connection is also among the conditional disadvantages.

The third largest and one of the very first pools that were created (2010). Great for beginners because of the simple interface and navigation. A huge advantage is that the servers are located all over the world, which provides good ping.

According to annual statistics, it takes 10.6% of the total hashrate. It is distinguished by high stability, reliable reputation and a program for demo mining (familiarization with the process for novice miners). The conditional disadvantages include the commission, which is slightly higher than that of the closest competitors - 2%.

A popular resource that allows you to mine BTC, Litecoin and 8 other major cryptocurrencies. According to the annual hash rate, it occupies the 7th position (6.8%). The downside can be considered increased commissions for major cryptocurrencies - 4%. The minimum commission on the server is only for Dashcoin, ETN and LTC, it is 2%.

A large mining pool, occupies 10.2% of the total network hashrate according to annual statistics. It does not require mandatory registration and supports the two most popular reward systems: PPS and PPLNS. The pool is registered in China and has been operating since 2013, during which time it has managed to gain a reliable reputation and a huge number of participants.

TOP 3 pools for Ethereum

Consider the top of the largest and most famous pools that make it possible to efficiently mine Ethereum.

One of the largest pools, the second most powerful among all servers (24-26% of the total annual hashrate). The number of participants exceeds 140 thousand people. It also allows you to mine "coins" without registration. The only significant disadvantage is an additional fee of 0.001 ETH, which is charged when withdrawing less than 1 ETH.

The undisputed leader, which takes 1st place in terms of power for Ethereum (28.7% of the power on the average annual rate). Supports the extraction of 5 "coins", among which are quite rare Beam and Grin. Reward system - PPS+ (combines the benefits of PPLNS and PPS). For all "coins" the withdrawal fee is 1%.

One of the largest resources for the extraction of ether, as well as Zcash and several other "coins". Supports PPLNS reward system. It ranks 4th in terms of power among all servers for ETH (almost 11% of the total hashrate). Also considered one of the best RVN mining pools, it supports 8 cryptocurrencies in total.

The pool charges a commission of 1%.

TOP 3 pools for Monero

Among the pools that are very popular in Monero mining, the following servers are distinguished.

mineXMR

One of the main pools for mining Monero, with a share of the total network hashrate of 17-19%. It is considered one of the very first servers for Monero, which was launched in 2014. Reward system - PPLNS, fixed commission - 1%.
