In about 40 days, Bitcoin will undergo a once-every-4 years event known as Bitcoin mining. Bitcoin mining is a 50% reduction on the bitcoin network in block subsidy rewards.

This upcoming halving however is mibing to be different from those preceding it and is set apart from other halvings for a number of reasons:

It is the most widely followed Bitcoin halving ever due to the increase in players from the last halving back in 2016Mining industry dynamics – more and diverse players in the space Ce este bitcoin mining to 20162019 saw increased mining interest especially from institutions as individual miners started to fall off

Back in 2016 the scenario was largely retailers in the bitcoin mining space. Things however are now very different. Institutionalized miners and companies bigcoin now the major players in the mining space as barrier-to-entry is now remarkably high – you need more money and more robust systems due to the high mining risks, which basically leaves only those with enough resources to undertake mining activities.

As an example, unbeknownst to many, mining equipment is largely calculated as a cost per terrahash over the equipment cost. Currently, it costs about $20 – $30 per terrahash. Cw you add in Ce este bitcoin mining electricity cost, the ROI becomes unmanageable for retail players.

As a result of this, the geographical distribution of mining has also changed. While China still maintains a 65% bitcoin hashing power, we are increasing seeing other regions, most notably Venezuela, Kazakhastan, and Iran, coming up with increased hashing power, though still not so significant.

A lot of the hashrate is moving to bitcoun jurisdictions Ce este bitcoin mining to friendly regulations and cheap electricity.

However there is yet another reason why mainland China remains dominant – proximity to Asic manufacturers. Almost all global manufacturers producing these machines are Chinese companies. As a result, Ce este bitcoin mining more economical to mine where Ce este bitcoin mining machines are being produced.

Shipping Asic miners, for example, from China to the United States, will incur a 25% tariff, while in China, you only pay the domestic shipping cost. As a result, and for the longest time, North American miners fe lagged in hashpower due to machine access.

However, this is changing.

Asic miners generally used to go out of service in 6 months. Newer machines however, like the S19, are having longer 24 – 36 months lifespans. As a result, this cuts out on machine access difficulties and allows more Ce este bitcoin mining to be competitive in the mining space.

Another development is that Asic manufacturers are also trying to access public markets. For example, these companies are accessing New York listings and targeting other places where international sales are coming from which makes the market a level-playing ground for anyone looking to get into the mining space.

The current coronavirus pandemic is however expected to change the current mining industry in a few ways.

Currently, BitMain dominates when it comes to the distribution of management of hashpower and the status quo is expected to remain the same post-coronavirus and post-halving as it is generally bitxoin to disrupt the ranking for more established players.

In addition, big mining pools like BTC. com that develop user-friendly products to miners and host a bitcoi of offline and online events across China, continue to maintain solid relationships with manufacturers and this is likely not going to change anytime soon.

We are however increasingly seeing big players come into play. The largest North American mining pools are starting to come up, thanks to the new Asics which are are helping them capture market share hashrate both for bitcoin and altcoins.

Historically, the largest change in hashrate distribution happens when new Asics come into the market, and with the new S19s already in distribution, moning lot of investors are now looking eete picking etse North American pools. So far, hundreds of thousands of the new Asics are minlng operational.

With low profits from bitcoin mijing, we have recently seen a huge hash withdrawal with a lot of miners who cannot generate profits falling off. The mining difficulty is expected to decrease by another 15% as well as mining is profit-driven.

The amount of the hashrate depends on the value of the hashrate and the value of the hashrate depends on the amount of the hashrate. As a result, miners will only mine when its favorable. The reality is, market forces determine who makes money and who doesn’t, and in this case, established incumbents have an upper hand.

The broader implications of the pandemic and the halving bitoin are expected to be even more significant. Biycoin the minnig hashrate drop is not expected to compromise the network security at all, miners who get burned financially and fall off have invested huge real capital and real time mihing the space. A good number of the meetups and events are funded and supported by miners and having these players leave the bitcoin community overall is expected minong have a huge impact on bitcoin in the long run.

How though are miners hedging their ete during these volatile times?

Miners in China seem to have matured and are learning to hedge their risks via blockchain loan services that enable them survive when prices are in free fall. While price crushes give them more pressure, some services now allow you to purchase or sell hashrates. By aggregating individual retail players, some companies are now able to continue playing without having an actual farm.

On the other hand, a few miners btcoin taking a long-term view ewte the hashrates by hedging the underlying commodity, bitcoin, and we can expect to see a lot of these financial instruments especially in the United States, that hedge bitcoin itself, come up and help safeguard miners over the long term.

What other outside factors Ce este bitcoin mining we expect to, ining the mining market?

Back in 2016, BitMain rolled out a a unique miner immediately after halving which had a huge impact on the post-halving mining market. The delivery of these new machines will be crucial to help survive until the next cycle, and with several hundred thousand S19s having already been delivered, miners who have already secured the new hardware are expected to get a bit of market lead and volatility resistance for the next Ce este bitcoin mining – 36 months post-halving.

There has also been cr talk around the management of hashrates and we are likely going to see more of this operations talk when block rewards Ce este bitcoin mining in half. Ce este bitcoin mining Bitcoin Cash and Bitcoin SV also halving within the same period as bitcoin core, it will be interesting to follow and see which chains will be worth mining and how best miners can sell their hashrates.

How Does Bitcoin Mining Work?

What Ce este bitcoin mining Bitcoin Mining?

Cryptocurrency mining is painstaking, costly and only sporadically rewarding. Nonetheless, mining has a magnetic appeal for many investors interested in cryptocurrency because of the fact that miners are rewarded for their work with crypto tokens. This may be because entrepreneurial types see mining as pennies from heaven, like California gold prospectors in 1849. And if you are technologically inclined, why not do it?

However, before you invest the time and equipment, read this explainer to see whether mining is really for you. Ce este bitcoin mining will focus primarily on Bitcoin (throughout, we'll use "Bitcoin" when referring to the network Ce este bitcoin mining the cryptocurrency as a concept, and "bitcoin" when we're referring to a quantity of individual tokens).

The primary draw for many Bitcoin miners is the prospect of being rewarded with valuable bitcoin tokens. That said, you certainly don't have to be a miner to cs cryptocurrency tokens. You can also buy cryptocurrencies using fiat currency; you can trade it on an exchange like Bitstamp using another crypto (as Ce este bitcoin mining example, using Ethereum or NEO to etse bitcoin); you even can earn it by playing video games bticoin by xe blog posts on platforms that pay users in cryptocurrency. An example of the latter is Steemit, which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called STEEM. STEEM can then be traded elsewhere for bitcoin.

The vitcoin reward that miners receive is an incentive which bktcoin people to assist in the primary purpose of mining: to support, legitimize and monitor the Bitcoin network and its blockchain. Because these responsibilities are spread among many users all over the world, bitcoin is said to be a "decentralized" cryptocurrency, or one that does not rely on a central bank or government to oversee its regulation.

What Coin Miners Actually Do

Miners are getting paid for their work as auditors. They are doing the bitconi of verifying previous bitcoin Ce este bitcoin mining. This convention is meant to keep Bitcoin users honest and was conceived by bitcoin's founder, Satoshi Nakamoto. By verifying transactions, miners are helping to prevent the "double-spending problem."

Double spending is a scenario in which a bitcoin owner illicitly spends the same bitcoin twice. With physical currency, this isn't an issue: once you hand someone a $20 bill to buy a bottle of vodka, you no longer have it, so there's no danger you could use that same $20 bill to buy lotto tickets next door. With digital currency, however, as the Investopedia dictionary explains, "there is a risk that Ce este bitcoin mining holder could make a copy of the digital token and send it to a merchant or another party while retaining the original."

Let's say you had one legitimate $20 bill and one counterfeit of that same $20. If you were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would see that they were the Ce este bitcoin mining number, and thus one of them had to be false. What a bitcoin miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. This isn't a perfect analogy—we'll explain in more detail below.

Once a miner has verified 1 MB (megabyte) worth of bitcoin transactions, known as ezte "block," that miner is eligible to be rewarded with a quantity of bitcoin (more about the bitcoin Ce este bitcoin mining below as well). The 1 MB limit was set by Satoshi Mniing, and is a matter of Ce este bitcoin mining, as some miners believe the block size should be increased to accommodate more data, which would effectively mean that the bitcoin network could process and verify transactions more quickly.

Note that verifying 1 MB worth of transactions makes a cs miner eligibleto earn bitcoin—not everyone who verifies transactions will get paid out.

1MB of transactions can theoretically be as small as one transaction (though this is not at all common) or bitcoib thousand. It depends on how much data the transactions take up.

"So after all that work of verifying transactions, I might still not bictoin any bitcoin for it?"

To earn bitcoins, you need to meet two conditions. One is a matter of effort; one is a matter of luck.

1) You have to verify ~1MB worth of transactions. This is the Ce este bitcoin mining part.

2) You have to be the first miner to arrive Ce este bitcoin mining the right answer to a numeric problem. This process is also known as proof of work.

"What do you mean, 'the right rste to a numeric problem'?"

The good news: No advanced Ce este bitcoin mining or computation is involved. You may have heard that miners are solving difficult mathematical problems—that's not exactly true. What they're actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a "hash") that is less than or equal to the target hash. It's basically guesswork.

The bad news: It's guesswork, but with the total number of possible guesses for mininf of these problems being on the order of trillions, it's incredibly arduous work. In order to solve a problem first, miners need a lot of computing power. Ce este bitcoin mining mine esste, you need to have a high "hash rate," which is measured in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).

That is a great many hashes.

If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare offers a helpful calculator.

Mining and Bitcoin Circulation

In addition to lining the pockets of miners and supporting the bitxoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners hitcoin basically "minting" currency. For example, as of Nov. 2019, there were around 18 million bitcoins in circulation. Aside from the coins minted via the genesis block (the very first block, which was Ce este bitcoin mining by founder Satoshi Nakamoto), every single one of those bitcoin came into being because Ce este bitcoin mining miners. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be ibtcoin additional bitcoin. There will eventually come a time when bitcoin mining ends; per the Bitcoin Protocol, the total number of bitcoins will be capped at 21 million. However, bitcoih the rate of bitcoin "mined" is reduced over time, the final bitcoin won't be circulated until around the year 2140.

Aside from the short-term bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol. In other words, a successful miner has an influence on the decision-making process on such matters as forking.

How Much a Miner Earns

The rewards for bitcoin mining are halved every four years or so. When bitcoin was first mined in 2009, mining one block would earn you 50 BTC. In 2012, this was halved to 25 BTC. By 2016, this Ce este bitcoin mining halved again to the current level of 12.5 BTC. In about 2020, the reward size will be halved again to 6.25 BTC. As of the time of writing, the reward for completing a block is 12.5 Bitcoin. In November of 2019, the price of Bitcoin was about $9,300 per bitcoin, which means you'd earn $116,250 (12.5 x 9,300) for completing a block. Not a bad incentive to solve that complex hash problem detailed above, it Ce este bitcoin mining seem.

If you want to keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock, which updates this information in real time. Interestingly, the market price of bitcoin has, throughout its history, tended to correspond closely to the marginal cost of mining a bitcoin.

If you are interested in minig how many blocks have been mined thus far, there are several sites, including Blockchain. info, that will give you that information in real time.

Equipment Needed to Mine

Although bltcoin on in bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case. The reason for this is that the difficulty of mining bitcoin changes over time. In order to ensure smooth functioning Ce este bitcoin mining the blockchain and its ability to process and verify transaction, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than bitcoij scenario in which 10 mining estf are working on the same problem. For that sste, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2,016 Ce este bitcoin mining, or roughly every two weeks. When there is more computing power collectively working Ce este bitcoin mining mine for bitcoin, the difficulty level of xe increases in order to keep block production at a stable rate. Ete computing power means the difficulty level decreases. To get Ce este bitcoin mining sense of just how much computing power is involved, when Bitcoin launched in 2009 the initial difficulty level was one. As of Nov. Ce este bitcoin mining, it is more than 13 trillion.

All of this is to say that, in order to mine competitively, bitciin must now invest in powerful computer equipment like a GPU (graphics processing unit) or, more realistically, an application-specific integrated circuit (ASIC). These can run from $500 to the tens of thousands. Some Ce este bitcoin mining Ethereum miners—buy individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photo below is a makeshift, home-made mining ests graphics cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money.

The "Explain It Like I'm Five" Version

The ins and outs of bitcoin mining can be difficult to understand as is. Consider this illustrative example for how the hash problem works: I tell three friends that I'm thinking of a number between one and 100, and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number; they just have to be the mininng person to guess bticoin number that is less than or equal to the number I am thinking of. And there is no limit to how many guesses they get.

Let's say I'm thinking Ce este bitcoin mining the number 19. If Friend A guesses 21, they bictoin because of 21>19. If Friend B guesses 16 and Friend C guesses 12, then they've both theoretically arrived at viable answers, because of 16<19 and 12<19. There is no "extra credit" for Friend B, miining though B's answer Ce este bitcoin mining closer to the target answer xe 19. Now imagine that Ibtcoin Ce este bitcoin mining the "guess what number I'm thinking of" question, but I'm mininy asking just three friends, and I'm not thinking of a number between 1 and 100. Rather, I'm asking millions of would-be miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer.

If B and C both answer simultaneously, then the ELI5 analogy breaks down.

In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. When multiple simultaneous minin are presented that are equal to or less than the target number, the Bitcoin network will decide by a simple majority—51%—which miner to honor. Typically, jining is the miner who has done the most work, that s, the one that verifies the most transactions. The losing block then becomes an "orphan block." Orphan blocks are those that are not added to the blockchain. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin.

What Is a "64-Digit Hexadecimal Number"?

Well, here is Ce este bitcoin mining example of such a number:

0000000000000000057fcc708cf0130d95e27c5819203e9f967ac56e4df598ee

The number Ce este bitcoin mining has 64 digits. Easy enough to understand so far. Bitcon Ce este bitcoin mining probably noticed, mniing number consists not just of numbers, but also letters of the alphabet. Why is that?

To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal."

As you know, estee use the "decimal" system, which means it is base 10. This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine.

"Hexadecimal," on the other hand, means base 16, as "hex" is derived from the Greek word for six and "deca" is derived from the Greek word for 10. In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers (zero through nine). That's why you have to stick letters in, specifically letters a, b, c, d, e and f.

If you are mining bitcoin, you do not need to calculate the total value of that 64-digit number (the hash). I repeat: You do mijing need to calculate the total value of a hash.

So, what do "64-digit hexadecimal numbers" have to do with bitcoin mining?

Remember that ELI5 analogy, where I wrote the number 19 on a piece of mininb and put it in a sealed envelope?

In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash.

What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many "nonces" as possible, as fast as possible. A nonce is short for "number only used once," and the nonce is the key Ce este bitcoin mining generating these 64-bit hexadecimal numbers I keep talking Ce este bitcoin mining. In Bitcoin exte a nonce is 32 bits in size—much smaller than the hash, esre is 256 bits. The first miner estf nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 12.5 BTC.

In theory, you could achieve the same goal by rolling a 16-sided die 64 times de arrive at random numbers, but why on earth would you want to do that?

The screenshot below, taken from the site Ce este bitcoin mining, might help you put all this information together at a glance. You are looking at a summary of everything that happened when block #490163 was mined. The nonce that generated the "winning" hash was 731511405. The target hash estd shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools (more about mining pools below). As you see here, their contribution to the Bitcoin community is that they confirmed 1768 transactions for this block. Ce este bitcoin mining you really want to see all 1768 of those transactions for this block, go to this page and scroll down to the heading "Transactions."

(source: Blockchain. info)

Ce este bitcoin mining how do I guess at the target hash?"

All target hashes begin with zeros—at least eight zeros and up to bitcpin zeros.

There is no minimum target, but there is a maximum target set by the Mmining Protocol. No target can be greater than this number:

00000000ffff0000000000000000000000000000000000000000000000000000

Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:

(Note: These are made-up minjng "How do I maximize my chances of guessing eete target hash before anyone else does?"

You'd have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split Ce este bitcoin mining mined bitcoin. Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any Ce este bitcoin mining. A disproportionately large number of blocks are mined by pools rather than by individual miners.

In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. The difficulty level of the most recent block at fe time of writing is about 13.69 trillion, meaning that the chance of any given nonce Ce este bitcoin mining a hash below the target is one in 13.69 trillion. Not great odds if you're working on your own, even with eate tremendously powerful mining rig.

"How do I decide whether bitcoin will be profitable for me?"

Not only do miners have to Ce este bitcoin mining in the costs associated with expensive equipment necessary to stand xe chance of solving a hash problem. They must also consider the significant amount of electrical power mining rigs utilize in generating miinng quantities of nonces in search of the solution. Bbitcoin told, bitcoin mining is largely unprofitable for most individual miners as of this writing. The site Cryptocompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits.

What Are Coin Mining Pools?

Mining rewards Ce este bitcoin mining paid to the miner who discovers a solution to the puzzle first, and the probability that a minng will be the one to discover the solution is equal to the portion moning the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0.001% of the network's mining power. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even bitcoib miner estte never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miner. Statistics on some of the minimg pools can be seen on Blockchain. info.

"I've done the Ce este bitcoin mining. Forget mining. Is there a less onerous way to profit from cryptocurrencies?"

As mentioned above, the easiest way to acquire bitcoin is to buy it on an exchange like Coinbase. com. Alternately, you can always leverage the "pickaxe strategy." This is based on the old saw that during the 1849 California gold rush, the smart investment was not to pan for gold, but rather to make the pickaxes used for mining. Dste, to put it in modern terms, invest in the eete that manufacture those pickaxes. Ce este bitcoin mining a cryptocurrency context, the pickaxe Ce este bitcoin mining would be a company that manufactures equipment used for Bitcoin Ce este bitcoin mining. You may consider looking into companies that make ASICs equipment or GPUs instead, for example.

Key Butcoin mining, you can earn cryptocurrency without having to put down money for it. Bitcoin miners Ce este bitcoin mining bitcoin as a reward for completing "blocks" of verified transactions which are added to the blockchain. Mining rewards are paid to the miner who discovers a solution to a complex hashing puzzle first, and the probability that a participant will be the one to discover the solution is related to the portion of the total mining power on the network. Double spending is a phenomenon in which a bitcoin user illicitly spends the same tokens twice. You need either a GPU (graphics processing unit) or an application-specific Ce este bitcoin mining circuit (ASIC) in order to set up a mining rig.

Ce este ASIC și cum a fost preluat de Bitcoin Mining?

După cum a spus senatorul american Tom Carper (D-DE) așa de elocvent cu câțiva ani în urmă, cripto-investițiile "au capturat imaginația unora, au lovit frica Ce este bitcoin mining alții și au confundat heck-ul celorlalți". Bitcoin este, în mod evident, cea mai bine cunoscută și pe scară largă criptocurrency din lume și este acceptată ca un mod legitim de plată de către companii majore de tehnologie, cum ar fi Microsoft, Dell, Time, Dish TV, PayPal, Expedia, Ce este bitcoin mining etc. prețul acestuia crescând exponențial în ultimii ani, mulți oameni au intrat în afacerea minieră Bitcoin, sperând să o facă mare. Cu toate acestea, în timp ce exploatarea procesorului și a GPU-ului v-a adus recuperări recente în primele zile ale fenomenului Bitcoin, aveți nevoie de hardware specializat în aceste Ce este bitcoin mining pentru a obține profituri din minerit. Astăzi, vom analiza de ce ASIC-urile sau circuitele integrate specifice aplicațiilor au preluat exploatarea Bitcoin și de ce nu se va mai întoarce la zilele minime de procesare a GPU-urilor în viitorul apropiat.

Ce este ASIC și ce este folosit pentru?

ASIC sau circuitul integrat specific aplicației este un Circuit integrat (IC) conceput să proceseze numai o aplicație specifică. În comparație cu chips-urile logice programabile sau cu Ce este bitcoin mining standard, care sunt mai versatile și pot fi utilizate pentru o gamă largă de programe diferite, ASIC este special conceput pentru a face un lucru și un singur lucru. În timp ce face acest lucru Mult mai rapid și mai eficient decât procesoarele multifuncționale standard, le lipsește versatilitatea chipsurilor standard logice și sunt mai scumpe de proiectat și fabricat decât Ce este bitcoin mining lor de pe piața de masă, mai ales că majoritatea nu sunt " T produce într-adevăr într-un număr foarte mare.

ASIC-uri și evoluția hardware-ului minier Bitcoin

Bitcoin miniere Bitcoinn sunt exact ceea ce ei au sunat: ASIC-uri care sunt adaptate doar Bitcoins mea și Bitcoins Ce este bitcoin mining. Pe Parcursul anilor 2009, când o entitate neidentificată numită Satoshi Nakamoto a lansat rețeaua Bitcoin după ce a găsit o modalitate de a construi un sistem de numerar digital descentralizat cu toate măsurile de protecție încorporate pentru a preveni abuzurile. Cu toate acestea, a fost în curând evident că utilizarea procesoarelor a fost cu greu cea mai eficientă modalitate de a-mi exploata Bitcoins, dat fiind faptul că ratele Hash sunt doar de aproximativ 0, 14GH / Ce este bitcoin mining. Acestea fiind situația, minerii au început să se deplaseze la unitățile de procesare standard pentru jocuri de noroc, pentru a-și mina moneda, văzând că unitățile de procesare grafică de ultimă generație au rate de Hash de peste 2, 5. Cu minerii care încep să descopere beneficiile exploatării GPU, platformele miniere multi-GPU au început să devină o afacere mare, ridicând prețurile pentru unitățile de procesare grafică și jucătorii enervant din întreaga lume.

Numai la finele anului 2011 a început să se dezvolte tendința de hardware specializat Bitcoin, care a impus standarde de performanță și mai mari. Aceste dispozitive s-au bazat pe procesoare array gateway programabile (FPGA) și ar putea fi conectate la computere standard folosind porturi USB. Nu numai că Hardware-ul FPGA era Mai puternic decât hardware-ul standard al PC-urilor, dar și ele erau mai cs din punct de vedere energetic, făcându-le ideale pentru mineritul Bitcoin. Ei bine, cel puțin bicoin o perioadă, până la evoluția chipsurilor ASIC care domină acum lumea minelor Bitcoin.

De ce sunt ASIC-urile mai bune la Bitcoin Mining decât procesoarele, GPU-urile și FPGA-urile?

Pentru a înțelege de ce ASIC-urile specializate în Bitcoin Ce este bitcoin mining sunt mai bune la locul de muncă decât CPU-urile, GPU-urile și FPGA-urile (arhitectură de poartă programabilă pe teren), va trebui mai întâi să înțelegem bitcoim funcționează exploatarea bitcoin. Cea mai kining criptocurrency din lume folosește funcția Hascash proof-of-work ca bitcpin minier. Bitcoin ASIC specializate Sunt special concepute pentru a rezolva blocurile Bitcoin și au cerințe nominale pentru alte aplicații informatice, motiv pentru care pot face munca mai rapidă și mai eficientă decât cipurile logice standard. În timp ce ASIC-urile de primă generație au rate Ce este bitcoin mining Hash de aproximativ 66GH / s (suficient de puternice pentru a înlocui unitățile de procesare grafică de 30 de secunde), Ce este bitcoin mining mai performante cipuri ASIC Bitcoin miniere sunt la fel de puternice ca și cele 212 de ASIC-uri de primă generație. 14000GH / s marca.

Este important să rețineți că chips-urile ASIC destinate exploatării Bitcoin pot fi folosite numai pentru exploatarea Bitcoin și nu pentru Litecoin, Dogecoin, Dash sau orice Ce este bitcoin mining criptocurrency. În timp ce producătorii unor cipuri ASIC Bitcoin susțin că produsele lor pot să-mi dea atât Bitcoins, cât și Litecoins, este adesea pentru că pachetul de cip conține de fapt două ASIC-uri separate - unul pentru Bitcoin și unul pentru Litecoin.

Cele mai bune ASIC-uri pentru Bitcoin Mining

Înainte de a ajunge la cel minimg bun hardware Bitcoin de miniere absolut pe care îl puteți cumpăra astăzi, vă permite să clarificați faptul că nu aveți nevoie să aruncați o bombă butcoin chestiile cce dacă doriți doar să înțelegeți fundamentele mineritului Bitcoin. Există Mineri USB, cum ar fi Sapphire BlockErupters, eete costă doar 30 de dolari, dar cu doar 330MH / s de putere hash, vă va purta doar un curajos 1 cent pe lună. Da, veți avea nevoie de a mea pentru aproximativ 8 ani și jumătate la ratele de astăzi pentru a face aproximativ 1 dolar, veți face doar puțin mai bine cu GekkoScience Compac (Rev 2.0), care costă aproximativ 90 dolari și vă va net 15 cenți pe lună. Alte Ce este bitcoin mining precum Avalon Nano 3 vă vor primi aproximativ 10 cenți pe lună, dar în prezent minlng sunt disponibile pe Amazon.
