Jihan Wu, the CEO of Bitmain, claims that 70 percent of the Bitcoin mining rigs in operation today were made by his company. Bitmain acquired this mining facility in Inner Mongolia a couple years ago and has turned it into one of the most powerful money factories on the Bitcoin network.

It quite literally metabolizes electricity into money. By my own calculations, the hardware on the grounds—some 21, computers—accounted for about 4 percent of all the computing power in the Bitcoin network when I visited. Like ton paperweights, these machines bear down on the globally distributed ledger of transactions that is Bitcoin, keeping its pages from ever turning backward.

Here is where the supply of existing bitcoins is secured. And here is where the banquet of new bitcoins is served.

The process of mining bitcoins works like a lottery. Bitcoin miners are competing to produce hashes—alphanumeric strings of a fixed length that are calculated from data of an arbitrary length. Each time miners perform the hash function on the block header with a new random number, they get a new result. To win the lottery, a miner must find a hash that begins with a certain number of zeroes.

Just how many zeroes are required is a shifting parameter determined by how much computing power is attached to the Bitcoin network. Every two weeks, on average, the mining software automatically readjusts the number of leading zeros needed—the difficulty level—by looking at how fast new blocks of Bitcoin transactions were added.

The algorithm is aiming for a latency of 10 minutes between blocks. When miners boost the computing power on the network, they temporarily increase the rate of block creation. The network senses the change and then ratchets up the difficulty level. Then two things happen. New transactions are added to the Bitcoin blockchain ledger, and the winning miner is rewarded with newly minted bitcoins. The miner also collects small fees that users voluntarily tack onto their transactions as a way of pushing them to the head of the line.

The probability of an individual miner winning the lottery depends entirely on the speed at which that miner can generate new hashes relative to the speed of all other miners combined. In this way, the lottery is more like a raffle, where the more tickets you buy in comparison to everyone else makes it more likely that your name will be pulled out of the hat.

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.

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. 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.
