What is Bitcoin mining Module?
The work done by the component which is assigned in a Bitcoin mining pool is known as Bitcoin mining module. Earlier it used to be very easy to extract Bitcoin out of a Bitcoin mining pool by using personal computers. But now a days things are getting harder as the supply of Bitcoins is very short and only 21 million Bitcoins could ever be extracted. Limitation has been put on by the underlying algorithm of the Bitcoin itself. As there are more miners than earlier times; more and more computing resources are employed to mine the Bitcoin. As normal computing resources could no longer work to mine the cryptocurrency; therefore newer and powerful Bitcoin mining modules are being deployed to mine the cryptocurrency now-a-days.
Application specific integrated circuits also known as ASIC miners are usually needed to mine the Bitcoin. Mining rigs are made arranging the GPUs the graphics cards in an alternating fashion to effectively mine the Bitcoin. As the prices of Bitcoins are shooting up the price of mining hardware too is showing the same pattern. One needs to be careful while picking the mining hardware to know which Bitcoin mining module is the constituent of it.

Top 14 Cryptocurrency Mining Hardware Kit Setups For Bitcoin Miners.
The Top 14 Hardware Setups for Crypto Mining.
If you want to mine cryptocurrency, then you need the right hardware. If you've got the right hardware, then you can start earning cryptocurrencies immediately. Today, we're highlighting the top 10 best hardware setups for crypto mining.
First, let's clarify something: in days gone by, anyone with a PC could mine bitcoin. Bitcoin mining took place via CPUs, and you could mine bitcoin using a laptop, if you wanted to. Then, Bitcoin mining moved to the GPU, which meant anyone with a powerful graphics card - like the card in a gaming PC - could mine cryptocurrencies. Today, we've mostly moved beyond GPU mining. Today, most crypto mining takes place using Application Specific Integrated Circuits, or ASICs, which are special machines designed specifically for mining cryptocurrency.
Second, the hardware setups listed below can be used to mine many different cryptocurrencies, including bitcoin, Ethereum, Litecoin, Zcash, and other cryptocurrencies. Some ASICs work well with specific cryptocurrencies, while others work across cryptocurrencies equally as well.
With that in mind, let's look at the top 14 hardware setups for crypto mining.
DragonMint T1 Miner.
The DragonMint T1 is one of the most popular and powerful Bitcoin mining hardware setups available today. It's a SHA256 rig with 16 TH of hashpower, putting it at the top of the list in terms of hashpower. It's also got an Ethernet connection and dual, nine-blade fans. The DragonMint T1 also comes with AsicBoost technology to minimize power consumption while maximizing hashrate, which means more profit for you.
The DragonMint is similar to other ASICs in terms of setup. You can adjust PW settings, access a stats dashboard, and update the firmware, for example. There's also a soft reboot function.
One of the most efficient bitcoin miners available today More hashrate than any other bitcoin miner Easy to setup Compatible with multiple mining pools.
You're typically restricted to AsicBoost mining pools High price and low availability.
The Antminer S7 was introduced in 2015, and it's been at the top of the crypto community ever since. The energy-efficient rig comes with a 28nm BMI1385 ASCI chip, a 1000W PSU, 4.73 TH/s of hashpower, and energy efficiency of 0.25 Joules per GH/s. The S7 also has DHCP capability, which means it will automatically scan for an IP to use.
The Antminer S7 works well in temperatures between 40 to 77 degrees Fahrenheit, making it popular in datacenters and basements worldwide. The Antminer S7 features an Ethernet port.
Affordable for hobby miners and mining farms alike Its popularity means there are plenty of guides and parts available High hashrate with good energy efficiency Twice as efficient as the S5.
Requires a source of cheap electricity to make a profit Designed specifically for Bitcoin mining.
The Antminer S9 is Bitmain's other popular mining ASIC after the S7. It's more powerful than the S7, but that power comes with added cost. Nevertheless, many people choose to purchase the S9 because it delivers three times the hashpower as the S7 without consuming significantly more electricity. That means you can earn significantly higher profits with the S7.
Other miners have similar hashrates to the S9, but few miners work as efficiently. Yes, you pay a premium for the S9, but the high efficiency allows you to earn back your money relatively quickly.
The S9 is a complete unit with no need to connect to other PCs. It has a built-in web management portal for easy setup and maintenance. The S9 has a power efficiency rating of 0.098 W/Gh, a weight of 8.1 pounds, and a 16nm chip. It has 3 circuit boards with a total of 189 chips, collectively delivering a hashrate of 13.5 TH/s.

Bitmain Antminer S1.
The Antminer S1 is one of the more basic and affordable options offered by mining giant Bitmain. If you're looking for an affordable way to learn how crypto mining works, then the Antminer S1 is one good option. It's also a popular miner for overclocking.
The S1 consumes about 407 W to 422 W when overclocked. When overclocked, you can expect hashrates of 180 GH/s to 200 GH/s, making the S1 significantly weaker than the miners listed above (of course, it's also significantly cheaper). The S1 does have the unique ability to connect via Ethernet or Wi-Fi. A dual blade unit keeps the rig cool even when overclocked.
Easy to setup and use Affordable Can be overclocked for higher hashrate.
Lower hashrate than the rigs above Power supply sold separately Minimal profits.
Bitmain Antminer S2.
The Bitmain Antminer S2 was launched in 2014 after the success of Bitmain's S1. The S2 introduced several upgrades over the S1, including better hashrate and better power consumption. It's also surprisingly quiet for a bitcoin miner: even when overclocked and mining, the S2 runs relatively quiet.
The S2 uses the same chip as the S1 (the BM1380). However, Bitmain tweaked the design for better power efficiency. The rig itself is squeezed into a 4U rack. Your S2 purchase comes with an Enermax-made PSU, so unlike the options above, there's no need to purchase a separate PSU.
Other notable features of the S2 include the 1000W power consumption, a power efficiency of 1 W per GH/s, and a 55nm chip. The Antminer S2 is an SHA-256 ASIC miner.
Surprisingly quiet Power efficient Affordable price.
Costlier than the S1 without delivering major performance improvements.
Avalon 741.
Avalon is a unique Bitcoin mining company. When ordering form Avalon, you'll need to order miners in larger batches - say, an order of 20, 50, or 100 miners. This makes Avalon more popular with larger Bitcoin mining organizations, but less popular among hobby miners.
If you manage to purchase an Avalon 741, then you'll get an efficient and powerful SHA-256 ASIC miner capable of delivering hashrates of 7.3 TH/s. It has a 16nm chip and the unit consumes approximately 1150W of power with a power efficiency rating of 0.16 Joules per GH. The operating temperature ranges from -5C to 40C.
Comes with Avalon management system that makes it easy to control multiple miners simultaneously Powerful and energy efficient Stable rig Stocked with useful accessories.
Typically purchased in batches instead of single-unit orders Not cheap.
Bitmain Antminer T9.
The Antminer T9 delivers a hashrate of 11.5 TH/s, although it's slightly less efficient than the S9. The T9 is typically purchased by those who emphasize reliability, as it's perceived to be more durable than the S9. The reason for the durability is that the T9 doesn't put the same pressure on its chips as the S9, which is why the unit tends to last longer.
As a testament to its durability, the T9 has a 180 day warranty - twice as long as the 90 days you get with the S9. The T9, like other Bitmain miners, is also easy to setup and manage.
The T9 has a power efficiency rating of 0.126 Joules per GH. It has an Ethernet connection, 16nm BM1387 chip technology, and an operating temperature of 0 to 40 degrees Celsius.
Powerful and efficient Lasts longer than the S9 Warranty is twice as long as the S9 Capable of mining several SHA-256 cryptocurrencies.
Less powerful and efficient than the S9, yet costs more.
Antminer L3/L3+ Scrypt Miner.
If you want to mine Litecoin, then the Antminer L3/L3+ Scrypt Miner is one of the more popular options. With a hashrate of 255 MH/s, the L3/L3+ is one of the best Litecoin mining ASICs available today. It outperforms other popular Litecoin ASICs, including the KnC Titan and the A4.
The L3 and L3+ both consume very little electricity, which means you can maximize profitability when mining. So the L3/L3+ isn't just a powerful rig: it's also extremely efficient and profitable. As a testament to the L3/L3+'s power, Litecion creator Charlie Lee tweeted that the L3 was 2.5 times more efficient than the A4, according to his experience.
Other notable features on the L3/L3+ include a BM1485 Litecoin ASIC chip, dual fans, exposed boards, and 1.6 Joules per MH power efficiency. There's no built-in power supply on the L3 or L3+.
One of the best ASICs for mining Litecoin More efficient than other Litecoin miners Built-in controllers with no separate PC required.
Exclusively designed for mining Litecoin Can be hard to purchase, and supplies are limited.
Bitmain Antminer R4.
The Antminer R4 is yet another bitcoin miner. The SHA-256 ASIC mining rig has an efficiency rating similar to the S9, along with a hash rate of 8.6 TH per second. The rig outperforms the S7 and delivers power similar to the S9. Like other Bitmain miners, it's easy to setup and run.
The R4 is a popular rig among hobby miners because of its small size, quiet operation, and slim form factor. It's easy to fit into a basement, a garage, or an office. It also delivers a surprisingly high hashrate without consuming excessive electricity. The R4 consumers power at an efficiency of around 0.098 Joules per GH.
Ultra-silent fans User-friendly design, interface, and setup As efficient as the S9, although with slightly lower power consumption Slim form factor.
Expensive Exclusively for Bitcoin mining.
The AMD Radeon R9 295X2 is one of the more popular Ethereum mining options available today. The "X2" in the name of this miner indicates that everything is doubled. The miner contains two Hawaii XT GPUs, for example.
The Radeon R9 delivers a hashrate of 46.0 MH/s, which makes it more powerful than most Ethereum mining GPUs available today.
To be clear, the R9 295X2 is just a GPU: you'll need a PC to start mining Ethereum. Unlike some of the mining rigs above, it's not a standalone unit.

Abstract.
Bitcoin is a "crypto currency", a decentralized electronic payment scheme based on cryptography. It implements a particular type of peer-to-peer payment system. Bitcoin depends on well-known cryptographic standards such as SHA-256. In this paper we revisit the cryptographic process which allows one to make money by producing new bitcoins. We reformulate this problem as a specific sort of Constrained Input Small Output (CISO) hashing problem and reduce the problem to a pure block cipher problem, cf. Fig. 1. We estimate the speed of this process and we show that the amortized cost of this process is less than it seems and it depends on a certain cryptographic constant which is estimated to be at most 1.89. These optimizations enable bitcoin miners to save countless millions of dollars per year in electricity bills.

Bitcoin mining, SHA-256 hash algorithm, a simple approach.
Bitcoin mining is a key part of the security of the Bitcoin system. The idea is that Bitcoin miners group a bunch of Bitcoin transactions into a block, then repeatedly performs a cryptographic operation called hashing zillions of times until someone finds a special extremely rare hash value. At this point, the block has been mined and becomes part of the Bitcoin blockchain. The hashing task itself doesn't accomplish anything useful in itself, but because finding a successful block is so difficult, it ensures that no individual has the resources to take over the Bitcoin system.

A cryptographic hash function takes a block of input data and creates a smaller, unpredictable output. The hash function is designed so there's no "short cut" to get the desired output -- you just have to keep hashing blocks until you find one by brute force that works. For Bitcoin, the hash function is a function called SHA-256. To provide additional security, Bitcoin applies the SHA-256 function twice, a process known as double-SHA-256.
In Bitcoin, a successful hash is one that starts with enough zeros. Just as it is rare to find a phone number or license plate ending in multiple zeros, it is rare to find a hash starting with multiple zeros. But Bitcoin is exponentially harder. Currently, a successful hash must start with approximately 17 zeros, so only one out of 1.4x1020 hashes will be successful. In other words, finding a successful hash is harder than finding a particular grain of sand out of all the grains of sand on Earth.

The following diagram shows a block in the Bitcoin blockchain along with its hash. The yellow bytes are hashed to generate the block hash. In this case, the resulting hash starts with enough zeros so mining was successful. However, the hash will almost always be unsuccessful. In that case, the miner changes the nonce value or other block contents and tries again.
The SHA-256 hash algorithm used by Bitcoin.
The SHA-256 hash algorithm takes input blocks of 512 bits (i.e. 64 bytes), combines the data cryptographically, and generates a 256-bit (32 byte) output. The SHA-256 algorithm consists of a relatively simple round repeated 64 times. The diagram below shows one round, which takes eight 4-byte inputs -- A through H -- then performs a few operations, and generates new values of A through H.
The blue boxes mix up the values in non-linear ways that are hard to analyze cryptographically. Since the algorithm uses several different functions, discovering an attack is harder. (If you could figure out a mathematical shortcut to generate successful hashes, you could take over Bitcoin mining.)
The Ma majority box looks at the bits of A, B, and C. For each position, if the majority of the bits are 0, it outputs 0. Otherwise it outputs 1. That is, for each position in A, B, and C, look at the number of 1 bits. If it is zero or one, output 0. If it is two or three, output 1.
The Σ0 box rotates the bits of A to form three rotated versions, and then sums them together modulo 2. In other words, if the number of 1 bits is odd, the sum is 1; otherwise, it is 0. The three values in the sum are A rotated right by 2 bits, 13 bits, and 22 bits.
The Ch "choose" box chooses output bits based on the value of input E. If a bit of E is 1, the output bit is the corresponding bit of F. If a bit of E is 0, the output bit is the corresponding bit of G. In this way, the bits of F and G are shuffled together based on the value of E.
The next box Σ1 rotates and sums the bits of E, similar to Σ0 except the shifts are 6, 11, and 25 bits.
The red boxes perform 32-bit addition, generating new values for A and E. The input Wt is based on the input data, slightly processed. (This is where the input block gets fed into the algorithm.) The input Kt is a constant defined for each round.
As can be seen from the diagram above, only A and E are changed in a round. The other values pass through unchanged, with the old A value becoming the new B value, the old B value becoming the new C value and so forth. Although each round of SHA-256 doesn't change the data much, after 64 rounds the input data will be completely scrambled.
What this means for mining hardware.
Each step of SHA-256 is very easy to implement in digital logic -- simple Boolean operations and 32-bit addition. (If you've studied electronics, you can probably visualize the circuits already.) For this reason, custom ASIC chips can implement the SHA-256 algorithm very efficiently in hardware, putting hundreds of rounds on a chip in parallel. The image below shows a mining chip that runs at 2-3 billion hashes/second;.
In contrast, Litecoin, Dogecoin, and similar altcoins use the crypt hash algorithm, which is intentionally designed to be difficult to implement in hardware. It stores 1024 different hash values into memory, and then combines them in unpredictable ways to get the final result. As a result, much more circuitry and memory is required for scrypt than for SHA-256 hashes. You can see the impact by looking at mining hardware, which is thousands of times slower for scrypt (Litecoin, etc) than for SHA-256 (Bitcoin).
The SHA-256 algorithm is surprisingly simple, easy enough to do by hand. (The elliptic curve algorithm for signing Bitcoin transactions would be very painful to do by hand since it has lots of multiplication of 32-byte integers.) Doing one round of SHA-256 by hand took me 16 minutes, 45 seconds. At this rate, hashing a full Bitcoin block (128 rounds) would take 1.49 days, for a hash rate of 0.67 hashes per day (although I would probably get faster with practice). In comparison, current Bitcoin mining hardware does several terahashes per second, about a quintillion times faster than my manual hashing. Needless to say, manual Bitcoin mining is not at all practical.[5]

Basic Crypto Mining Profitability Calculator - How Much Money Can I Make?|6:29

[Bitcoin]

A Reddit reader asked about my energy consumption. There's not much physical exertion, so assuming a resting metabolic rate of 1500kcal/day, manual hashing works out to almost 10 megajoules/hash. A typical energy consumption for mining hardware is 1000 megahashes/joule. So I'm less energy efficient by a factor of 10¹⁶, or 10 quadrillion. The next question is the energy cost. A cheap source of food energy is donuts at $0.23 for 200 kcalories. Electricity here is $0.15/kilowatt-hour, which is cheaper by a factor of 6.7 -- closer than I expected. Thus my energy cost per hash is about 67 quadrillion times that of mining hardware. It's clear I'm not going to make my fortune off manual mining, and I haven't even included the cost of all the paper and pencils I'll need.

SHA-256 Mining Hashrate Climbs Significantly in One Year.
Over the last year, SHA-256 mining, the process that's used to find blocks on both the Bitcoin Cash (BCH) and Bitcoin Core (BTC) networks, alongside a slew of other cryptocurrencies, has grown exponentially. Digital asset trading markets have been in a slump over the last eight months of 2018, but the bearish sentiment has not affected the hashpower behind these cryptocurrencies and, in fact, it has increased aggressively.
The SHA-256 Mining Hashrate Has Grown Considerably Large Over the Last Year.
The SHA-256 mining algorithm and other mining operations involve the process of computing devices verifying and compiling recent blockchain transactions, alongside solving computational problems in order to find a block. Miners who find a block are awarded freshly minted cryptocurrencies and all the fees associated with the transactions in the block. This incentivized system has grown significantly competitive which in turn has innovated both semiconductor production and a significant advancement in Exascale computing. Over the last few months, cryptocurrency markets have been bearish and prices have dropped considerably since the end of 2017. However hash power has not followed suit with the price and, in contrast, it has grown feverishly larger with each waking day.
Today BTC captures around 47 exahash per second while BCH holds a little above 4 exahash.
Bitcoin Cash Network Hashrate Has Increased Fourfold in One Year.
The Bitcoin Cash network at the time of writing is capturing around 4.13 exahashes per second today and over the last seven days, it's averaged around 4. Right now there's been over 65,000 BCH blocks mined since August 1, 2017, and the chain is over 6,600 blocks ahead of the bitcoin core (BTC) chain. On Sunday, August 19, 2018, the BCH chain is operating at 9.87 percent of BTC's sum block difficulty. Since last August the Bitcoin Cash network hashrate has increased remarkably and the amount of mining pools has notably changed as well. For instance, during the first week of August 2017, there were only a few mining pools processing BCH blocks such as Viabtc, Bitcoin.com, an unknown miner from Hong Kong, and a few other unknown miners. Weeks later on August 21 many other miners joined the BCH network such as Bitclub, Antpool, Batpool, and BTC.com bringing the BCH hashpower up to approximately 2 exahash.
A Variety of BCH Mining Pools and New Leaders.
Now a year later the BCH network has roughly 13 different mining pools including Coingeek, BMG Pool, Rawpool, BTC.com, Viabtc, Antpool, Bitcoin.com, BTC.top, Sbi Crypto, F2pool, Huobi, and a few unknown pools. Mining power has shifted hands since because twelve months ago the unknown miners and Viabtc commanded a large portion of the BCH hashrate. Now the biggest mining pool over the last seven days is Coingeek with 23.4 percent of the network hashrate over the last week and 31.9 percent today.
Then there are two to three unknown mining pools (can be differentiated by coinbase data) that hold about 20 percent of the BCH hashpower. The following top BCH miners include BMG Pool (10%), Rawpool (9.8%), BTC.com (8%), Viabtc (6.7%), and Antpool (6.5%). Other pools like F2pool and GMO Group have mined the BCH chain a few times over the past year as well. Essentially since the first week of August 2017, the BCH hashrate has grown fourfold and a lot more miners are processing BCH blocks.
Bitcoin Core Hashrate Climbs to 48 Exahash Per Second.
As far as the Bitcoin Core (BTC) network hashpower is concerned a lot has changed since 2017's first week of August. During the second week of August 2017, the BTC hashrate was around 8-6 exahash per second but has since increased 500 percent to around 48.2 exahash per second today. Hashrate distribution has changed quite a bit in the BTC mining world as well as there are now roughly 16 different mining pools. Right now there's an unknown miner processing 13.3 percent of the BTC network. The top BTC mining pools have also shifted quite a bit with the largest pool being BTC.com (16.6%) followed by pools such as Antpool (14.6%), unknown (13.3%), BTC.top (12.3%), and Slush Pool (11%).
The Use of Overt Asic Boost Touches a High This Month.
One particular interesting statistic is the use of overt "version-rolling" Asic Boost on the BTC network has increased since the Blockchain Defensive Patent License (BDPL) initiative was announced this past March. According to statistics, the use of Asic Boost whether overt or covert can increase mining efficiency by 20-30 percent. So far since March, the use of overt Asic Boost had crossed roughly 5 percent of the entire BTC network on August 1, 2018.
Asic Boost has captured 5 percent of blocks found a couple times so far in August.
On August 13 the network touch around 4.4 percent of all blocks found with Asic Boost and the average is around 3 percent today. Slush Pool has found the most blocks on the BTC network using overt Asic Boost (40%) while F2pool follows slightly behind (20%). Other mining pools utilizing Asic Boost include Ckpool, Bitclub, Bitfury, Wayi.cn, Poolin, and an unknown miner. The unknown mining pool commands 11 percent of the sum of all overt "version-rolling" Asic Boost blocks found.

The Largest Computational Systems Worldwide Have Pushed Semiconductor Tech Forward.
All of this means the power of SHA-256 mining has become one of the most powerful computational systems here on earth and it continues to grow. Further Satoshi's design to create an incentivized system that processes and verifies transactions has also pushed the envelope when it comes to semiconductor and MOSFET innovation. SHA-256 mining has excelled the creation of 10nm and 7nm chips which were one year behind schedule according to Moore's Law.
The GMO B3 uses 7nm chip technology while the Insilicon T2 uses 10nm chips. 5nm technology should meet production in 2-3 years and SHA-256 mining may make that timeline move faster.
These chips and the firms that have created super powerful mining rigs like GMO's B3 (33TH/s), Innosilicon's T2-Turbo (24TH/s), and Canaan's newly introduced Avalonminer A9 (26.5-30TH/s) should push the overall SHA-256 hashrate even more exponentially. There are only four foundries worldwide that manufacture 7nm chips (Samsung, Intel, TSMC, and Global Foundries) and Satoshi's creation has bolstered the demand for these innovative chips.
Markets may be bearish this year but the mining industry is growing faster than we can fathom, and the computational power behind Satoshi's invention proves more powerful than the fiat spot price per coin.
What do you think about this year's mining statistics continuing to grow stronger while the prices of cryptocurrencies have been floundering? Let us know what you think about this subject in the comment section below.
Top Bitcoin mining Stocks.
As the price of bitcoin shoots past new highs since the start of the year, the prospect of so-called Bitcoin mining becomes more and more alluring. Not surprisingly, companies that provide Bitcoin mining-related hardware, such as high-power graphics cards, are profiting from the Bitcoin mining boom. Fortunately for investors, some of these companies are publicly traded on the stock exchange.
Mining bitcoin refers to the generation of new bitcoin by bitcoin network participants who use their computational power to verify and process transactions on the bitcoin blockchain. By ensuring that the network is running smoothly and all correct transactions are being processed, bitcoin miners are financially rewarded with fresh bitcoin.
Currently, the bitcoin block reward is 12.5, which means that miners receive 12.5 bitcoins for every new block mined on the blockchain. A new block is created roughly every 10 minutes, contains several confirmed transactions, and will have had several miners involved in the process. Hence, the 12.5 new bitcoins will be split among the miners involved in the creation of the block. That means miners are in competition with each other to confirm more and more transactions to get a bigger piece of the Bitcoin mining rewards.
Therefore, there is somewhat of a hardware arms race among Bitcoin mining operations as they continuously try to increase the speed and efficiency of their mining rigs. One way of doing that is by investing in the newest and most powerful graphics cards that can be used to boost mining efficiency.
