Chia mining guide on SSD and HDD disks: setup and calculator

Today we will analyze in detail how to start mining Chia cryptocurrency on SSD and HDD disks, under the operating room Windows system. Let's create a wallet and form the Rafts, which we will place on the hard drives.

You've probably heard about the new virtualthe Chia Network (XCH) coin, claiming to be the "Bitcoin killer". Chia is one of the newest cryptocurrencies that debuted this year. The project was founded by Bram Cohen (who also invented BitTorrent) with the main goal of becoming the most energy efficient digital asset. Let's look at what the next rival of the Satoshi Nakamoto coin is.

Chia cryptocurrency mining

Chia mining farm for cryptography processinguses the resource of SSD and HDD drives, and not the computing power of graphics adapters or devices on integrated circuits, as more common blockchain currencies such as BTC and ETH. And, so mining Chia coins is a banal plotting, experienced miners will say, so what is revolutionary here?

Well, first of all, the requirements for mining Сhiamuch higher than previously launched cryptocurrencies with a similar method of generating new blocks. And secondly, no such project has caused so much hype. Over the past few weeks, Chia's popularity has grown so rapidly that it has caused a shortage of hard drives and SSDs in China that could soon be repeated in the US and around the world. The reason for this is a very well-run marketing campaign.

Key points in favor of a new blockchain project:

  1. If cryptocurrencies that do not have a fundamentalSince values ​​such as Dogecoin are rising in value fueled by the hype (Dogecoin has no coin limit and can inflate infinitely), it seems likely that Chia's price will rise as its popularity rises. The emission of a new digital asset is strictly limited and amounts to 21 million coinslike Bitcoin.
  2. Chia Uses New Consensus AlgorithmProof of Time (PoST) which essentially proves that you have unallocated space on your hard drive / SSD that can be used to create rafts. This is a big improvement, in terms of efficiency, over proof of work. When writing the source code for this cryptocurrency, the no less unique programming language Chialisp was used.

Will Chia beat Bitcoin, or at leastAt least one can only guess to take its rightful place among altcoins. But let's go directly to the main topic of our review and look at how to start mining the Chia coin.

At the time of this review, he had already enteredtrades, so we will be able to calculate a very real, and not a hypothetical profit. The mining profitability calculator for Chia can be opened by clicking on the link https://chiacalculator.com/.

Mining XCH can be compared to farming.The miner downloads specialized software from the official website of the project https://www.chia.net/ru/ and conducts a "sowing campaign" on his storage devices.

Each sown sector is called plot, which intranslated from English means "a piece of land", but its owner is called "a farmer." To generate a new block, the system broadcasts a set of codes to the farmers and each of them checks its plot in search of a suitable hash sum. The more “sown fields” you have, the higher the chances of closing the block. But at the same time, your iron must be sufficiently productive, otherwise the process of seeding the rafts will be greatly delayed and you will always be outstripped by farmers with more efficient "agricultural machinery".

When using proof of time (Proofof Time), it is necessary that the period of broadcasting calls between blocks be as short as possible. After all, proof of time is implemented in practice using the Verifiable Delay Function (VDF). Cryptographic calculations take a certain period of time, but are verified instantly.

The key idea behind the Verifiable Delay Function isthe need to carry out sequential computational operations on a set of parallel nodes, each of which is equivalent. At the same time, energy costs are minimized. The fastest and most powerful nodes of the network will be called Timelords (Time Lords). The developers assume that there will not be very many such VDF servers, which will exclude the appearance of controversial blocks. The fastest timelord will consistently finish first, closing the block and moving the chain forward, and competition between the Time Lords will help keep the network decentralized.

That is, unlike Bitcoin, which was initially mined on almost any dual-core CPU, Chia mining hardware requirements are initially quite highand with the growing popularity of green coins, they will be even more serious. So what does it take to build a farm?

Chia mining hardware

</p>

According to the developers, any userwho has a desktop computer, laptop, mobile phone or an account in the corporate network can participate in XCH farming. You just need to install the necessary software and have enough free space to create at least one raft, and then you can find the hash sum to close the next block and get a reward. Theoretically, this is quite possible, but it happens very rarely.

Ready assembly for Chia mining

To receive a guaranteed income from mining Chia, you need:

  • Quad-core processor with a clock speed of 1.5 GHz;
  • 2 GB of RAM;
  • Hard drive with a minimum capacity of 1TB.

It would seem that everything is very simple and inexpensive, but you are unlikely to earn anything on such an assembly. Here is one of the budget build options for Chia farming presented on the Miningclubinfo forum:

  • Motherboard GIGABYTE B550 AORUS MASTER;
  • CPU AMD Ryzen 9 5900X;
  • HDD SEAGATE Ironwolf Pro ST16000NE000 16 TB HDD SATA III 3.5;
  • HDD WD Purple WD82PURZ, 8 TB, HDD, SATA III, 3.5;
  • SSD drive SAMSUNG 980 MZ-V8V1T0BW 1 TB, M.2 2280, PCI-E x4, NVMe;
  • Memory module PATRIOT Viper Steel PVS464G300C6K DDR4 - 2x 32GB 3000, DIMM, Ret, 2 x 32GB, 3000MHz frequency.

With this set of components you canget to work. Although the total volume of hard drives is, of course, small and with a 1TB SSD, 32GB of memory will be used inefficiently. This miner will soon have an urgent need for additional seeding areas. Let's take a closer look at the hardware selection process.

Choosing an SSD and HDD disk

Chia mining guide on SSD and HDD disks: setup and calculator

</p>

In the XCH mining farm (this is the trading ticker of the Chia cryptocurrency), the most important element is the disk drive. Winchesters smaller than 1TB shouldn't even be considered... It is not recommended to buy devices withthe spindle speed is lower than 7200 rpm. We need capacious and fast HDDs with SATA3 interface. They are used directly to create rafts, each of which will be the standard 101.4Gib size. Disks will be formatted with NTFS, APFS, exFAT, ext4 file systems. But the FAT system is not suitable for plotting.

SSD drives are used to createtemporary files, from which the "sowing" takes place later. They have faster read / write speeds, which greatly improves your chances of being the first to find the next block. You can buy either SSD with a SATA3 interface of any size (2.5 inches or M.2), as well as NVMe SSDs that connect to M.2. But keep in mind that different M.2 connectors on the motherboard support different types of SSD (both SATA and NVMe). Read the motherboard specification carefully so as not to waste your money.

There are also more expensive serverdrives with increased wear resistance, but for now we will not seriously consider them. It is not known how the fate of this crypto project will turn out, therefore, greatly overestimate the costs of creating a farm. Also, pay attention to the recording method. It is best to take ordinary disks that work according to the CMR scenario. And here drives using SMR are slower and less reliable.

The best choice is size 3.5.2.5 laptop disks have worse mechanics, which means they have less resource. You can still buy a 1Tb WD Purple HDD for 4450 rubles. Larger drives are already slowly snapping up.

As for the auxiliary drive SATA SSD, we advise gamers to leave the models with memory QLC... The ideal option would be to rememberdevices with MLC flash memory, but in order to save money, it is quite possible to use SSD on TLC memory. An equally important component is the controller. Firstly, it must support a DRAM buffer, and secondly, it must withstand multiple data rewrites without failures. We can recommend SATA controllers Samsung, Silicon Motion (not XT), Marvell 88SS1074.

If you decide to buy NVMe, then keep in mind that thistype of drives, the controller heats up quite a bit and requires additional cooling. Otherwise, follow the same requirements as for SATA SSD. To increase the service life of solid statedrives are strongly recommended not to fill them by more than 85% of the total. Consider this when buying. And don't forget to buy another additional small SSD that will host the operating system. This is a mandatory requirement, otherwise mining will not start.

CPU

Chia Farm doesn't need an expensive gaming CPU. A stone operating at a frequency of 3 GHz and cooled by an ordinary boxed cooler is enough.

It must have at least 4 cores, or better 6 (ormaximum 8), and integrated graphics. Of course, you can connect a video card, but then you will occupy a PCI-e slot, which in the future could be useful for connecting another hard drive. For example, Intel Core i5-9400F BOX

RAM

Put more memory, minimum 2 GB. But 16 GB is better, and serious farmers immediately put 32 GB. Two 16 GB DDR4 bars with a frequency of 3200 MHz will be enough.

Motherboard

The most important thing when choosing a motherboard isSATA3 and USB 3.0 support. It should have as many ports as possible for connecting the HDD. Old boards from the secondary market will not work, buy modern ones. For example, MSI Z390-A Pro.

Installing the official program

</p>

You will see the project page on the serviceGithub, where you can download a complete node compatible with your operating system. We must pay tribute to Chia's team, they are not busy with efficiency. The coin has appeared quite recently, and software has already been released for almost all popular axes.

Full nodes are available for:

  • Windows (64bit);
  • macOS;
  • Ubuntu / Debian;
  • CentOS / Red Hat / Fedora;
  • Raspberry Pi 4;
  • Docker;
  • FreeBSD Install;
  • Ubuntu Binary Install;
  • OpenBSD Install.

For advanced users, there is special software to run the Chia node in a virtual environment, for example, on an Amazon cloud server.

For this, we have prepared detailed instructions: How to mine Chia cryptocurrency on the Amazon AWS cloud computing platform?

Since Chia Code Signing Certificate isnew, the software will be classified as "unsafe". You will have to forcibly save the download, and when you start the installer, you will need to select "Additional information" and "Run anyway".

Wallet

Well, where to store coins, someone will asknewbies. Like any other cryptocurrency, a full Chia node is a copy of the blockchain and a wallet that will receive rewards after you start mining.

Setting up plotting

Plotting is divided into two stages of creating parcelsor, to put it another way, plotting, and processing plots. The first step creates all of your evidence of free space by building seven cryptographic hash tables and storing them in a temporary directory.

Then this data is sorted and packed in a temporary directory and after that the dataset is moved to the final destination on the HDD.

Choosing the size of the raft (plot)

First you need to choose a size.The best option is k32, it will take up 108.8GB and will require 256.6GB of temporary SSD space to create it. Specify the number of rafts based on the size of one site and the amount of bins.

</p>

Set up hardware to maximumperformance can be done using the "Advanced Options" section. To reduce the load on the RAM, you can add more "baskets", that is, split the temporary file into a larger number of fragments. But keep in mind that the more baskets, the stronger the load on the SSD. Therefore, if you have 32 GB of RAM, it is better to reduce the number of baskets, on the contrary, by reducing the number of I / O requests for temporary files.

The number of processor threads depends on the numbersimultaneously created rafts. 1 section needs 1 stream. It is better not to touch the "Disable bitfield" item. Reverse sorting by bit field is faster and saves up to 12% of the total number of writes, although it requires more RAM. "Queue name" can also be omitted. But when errors appear in the plotting log, the queue name will help you figure out exactly when the failure occurred.

After everything is configured, click "Create a parcel»And the process of creating a raft will be launched. It can last from 4 to 12 hours, depending on the parameters of your equipment.

Parallel seeding

To get the maximum TB per day,you can build several graphs in parallel. The key is to correctly calculate the capabilities of your farm based on the size of the parcels, space for temporary files, the number of processor threads, and the amount of RAM.

Popular bugs

  • Let's talk about the pitfalls that inexperienced users most often come across.
  • Remember to set the power supply to maximum performance. If the computer goes into hibernation, the process will have to start over. The same goes for blackouts.
  • The path to the storage and the temporary folder cannot be written in Cyrillic, the program understands only the Latin font.
  • Be sure to create a separate directory on the disk, you cannot just write Disk C, the program will not understand you
  • Always run the Chia node as administrator.

If a failure occurs, then first try restarting the plotting, and if it does not help, delete the program folder in Windows / Users and then start the process again.

We have listed the simplest mistakes of beginner miners, let's move on to more complex cases.

Error RuntimeError: Unknown exception occurs for various reasons. It can be:

  • Russian letters to indicate the path to the directory.
  • Placement of the folder for temporary files on the same disk with the operating system.
  • Incorrect distribution of iron resources.

An error often occurs related to insufficient memory on disk for plotting. Carefully calculate the allowable number of rafts, otherwise you may see a message at the end of the log RuntimeError: bad allocation... On a 1TB SSD, you can create a maximum of 3 parcels at a time.

If you did not listen to our recommendations and nevertheless checked the box in the "Disable bitfield" column, then it is quite possible that an error will appear Caught plotting error: Bitfield plotting not supported by CPU... Uncheck this box and you should be fine.

It is recommended to check the finished plots forintegrity using PowerShell. Open the program and specify: C: Users "Username" AppDataLocalchia-blockchainapp-1.1.2resourcesapp.asar.unpackeddaemon

And then rewrite the path, indicating the drive and the name of the folder in which the generated rafts are located. If there are no mistakes, everything is in order, the "broken" area needs to be re-seeded, otherwise it will not yield a crop.

If there is no synchronization, try deleting inall available connections in the program interface. They will automatically update and areas synced to the network will be highlighted in green. In principle, you can start creating new rafts even before the end of the synchronization of your node. To speed it up, try opening port 8444 on your computer and on your router.

Profitability and payback

But is the game worth the candle?How profitable is the mining of this cryptocurrency? Recently, an article was published on the Overloker.ru portal entitled: "It's too late to get Chia Coin." The author calculated that to build the Chia mining farm, which will bring in 1 coin in 18 hours, the farmer must spend at least 1,200,000 rubles, or $ 16,263 at the current exchange rate.

At the same time, he assumed that one coin would becost $ 30. However, on May 12, one Chia token was sold on OKEx for $ 1069, and a couple of days before that the rate was even higher. The truth and complexity of mining is constantly growing and at the time of this writing, such a farm will mine one coin in three days. But still, the profitability is beyond praise.

Conclusion

Will the Сhia cryptocurrency replace Bitcoin,it is hard to say. So far, this is far from a fact, and most likely unlikely. But for a long time already in the blockchain industry there was no project that caused such a violent reaction from the media. At the time of writing this article, the hashrate of this network was 3.88 EB (4019898.88 TB). Three weeks ago, ten times less.

If it goes on like this, the price of toughdisks will skyrocket, and if the project goes bankrupt, the losses of miners will be simply enormous. True, it is worth noting that Chia is far from the only crypto coin available for plotting, there are 8 more similar projects.

However, one should not expect instantaneousexcess profit. Chia is more and more difficult to mine, equipment is becoming more expensive and liquidity is not too high. If the green coin is listed on Binance and a couple of other reputable exchanges, then you can safely invest in mining, or simply add it to your investment portfolio. However, the opinion of the author of the article should not be considered the ultimate truth. Whether or not to invest in this project is a private matter for everyone.
