These dynamics have resulted in a race among miners to amass the fastest, most energy-efficient chips. And the demand for faster equipment has spawned a new industry devoted entirely to the computational needs of Bitcoin miners. Until late , generic graphics cards and field-programmable gate arrays FPGAs were powerful enough to put you in the race.

But that same year companies began to sell computer chips, called application-specific integrated circuits ASICs , which are specifically designed for the task of computing the Bitcoin hashing algorithm.

Today, ASICs are the standard technology found in every large-scale facility, including the mining farm in Ordos. Bitmain gained an edge by supplying a superior product in large quantities, a feat that has eluded every other company in the industry. According to company specs, the S9 is capable of churning out 14 terahashes, or 14 trillion hashes, every second while consuming around 0. Although BitFury claims to be producing chips whose performance is nearly identical to those used in the S9, the company has packaged them into a very different product.

A control board on the top of the machine coordinates the work, downloading the block header to be hashed and distributing the problem to all the hashing engines, which then report back with solutions and the random numbers they used to get them. The standard algorithm takes 64 steps to complete, but in Bitcoin it is run twice for each block header, meaning a full round requires steps that are heavy on integer addition.

Despite having similar needs, there is a good deal of diversity in how chip designers build their hashing engines, says Hanke, who also served as the chief technology officer of a now-defunct mining rig manufacturer called CoinTerra. For example, Bitmain uses pipelining—a strategy that links the steps in a process into a chain in which the output of one step is the input of the next. Bitmain competitor BitFury has chosen not to use that technology.

The most pressing problem in the mining chip design is power efficiency, because your return on investment is the difference between how much money you spend on electricity versus how many new bitcoins you can win. A controller on top of the machine samples the ambient temperature and sets the fan speed and the voltage and clock speed of the machine accordingly.

A young man named Zhang brings me inside, shouting over a deafening whir. All along a wall of the warehouse, the windows have been removed from their frames and replaced with desert fans—panels of twisted, tightly packed metal strips that are being doused with water from a pipe above.

The Frustrating, Maddening, All-Consuming Bitcoin Energy Debate

Zhang walks up to a door between two shelves full of mining rigs, and we step through. The exhaust fans from all the mining machines on the other side are poking out through little holes in a metal wall, blasting hot air into the space, where it gets purged to the outside by another wall full of giant metal fans. Dust is a problem as well, which is why the interior of every warehouse I walk through is veiled in a fine fabric filter. To save money on cooling, some mine operators have opted for cooler climates. BitFury also runs three large mining facilities, one of which is in Iceland to benefit from the cool weather.

The other two BitFury mines are in Tbilisi, in the Republic of Georgia, where the weather is much warmer. According to Vavilov, the company has developed a two-phase immersion cooling technology with their subsidiary, Allied Control. The system bathes the mining machines in a dielectric heat-transfer liquid called Novec, which cools the computers as it evaporates.

The system is now deployed at the Georgia data centers. While heat is definitely an issue for the mining farm in Ordos, the electricity there is dirt cheap, only 4 U. The only other costs for the facility are the rigs themselves and the salary of the few dozen staff that keeps them operational. Zhang is part of that staff. He recently graduated from college in Inner Mongolia and started working at the mine only a few months ago. He describes himself as a technician, then points to a man who is standing on a pneumatic lift pulling a mining rig out of the racks.

The controller on the S9 has a red light that goes off when it detects a malfunction. Technicians like Zhang are on hand to scan the racks for sick rigs.

How Iceland became the bitcoin miners’ paradise

When they find one, they pull it out and send it to a house on the factory lot where other technicians diagnose the problem, fix it, and get the machine back on the line. Every moment the rigs spend unplugged, potential revenue slips away. And this is just one of the facilities that Bitmain runs.

Within a week it was back up, and approaching an all-time high. Price fluctuations, which have been common in Bitcoin since the day it was created eight years ago, saddle miners with risk and uncertainty. And that burden is shared by chip manufacturers, especially ones like Bitmain, which invest the time and money in a full custom design. According to Nishant Sharma, the international marketing manager at Bitmain, when the price of bitcoin was breaking records this spring, sales of S9 rigs doubled.

But again, that is not a trend the company can afford to bet on.

And so, Bitmain has begun to diversify. They mint new coins that are more often than not sold on the market so they can keep their operations running.

Miners help secure the network and are rewarded for doing so. Most cryptocurrencies — including bitcoin, ether, and Litecoin — reward miners with a specific amount of coins per block found, plus the amount of collected fees included in the transactions in the block they found. When blockchains get clogged over large transaction volumes, miners make a profit as users start competing with each other to get their transactions included in the next block.

This competition sees them bid on higher fees, that go directly to the miners that find the right blocks.



Getting into cryptocurrency mining can, however, be challenging for newcomers to the space. Finding the right hardware to buy to make a profit is a challenge, and setting it up properly with the right cooling system and finding the right energy prices to keep healthy margins may be reserved for larger operations only. To tackle these challenges cloud mining was created. Cloud mining lets users mine crypto assets using rented cloud computing power without having to buy, install, and run the hardware themselves.
