Electricity in Jakarta , Indonesia costs three cents per kilowatt hour. Instead, Triyanto has created a very precise and complex mining platform using his own — secret — configurations. To keep things from burning up Triyanto aims his machines in different configurations and maintains air conditioners that run in his home all night and day.
When I started I was too eager to get it working and missed a lot of testing. In short, this complex, expensive, and seemingly profitable mining rig is about to be eclipsed by newer and better technologies at a pace far faster than the average user can match. Bitcoin mining is like making money out of thin air. Bitcoin is a mix of three monetary processes. First, it handles its own transaction processing think credit card companies, fraud prevention the SEC and security firms , and currency issuance the treasury.
In a real world these things are very complex systems with many moving parts. The beauty of Bitcoin is that each of these systems are reduced to very simple, very powerful cryptographic methods that ensures that each step in the chain verifies the next.
These blocks are sent out every ten minutes as a package of cryptographically verified transactions — the buys and sells of the system. And then the boulder rolls down again. Groups can get together and mine concurrently, sharing in the proceeds, but the resulting payouts are minuscule — perhaps a few dollars per day at the very most.
The goal of processing is to find a hash that has a sufficient numbers of zeroes at the beginning. This signals the completion of the block and pays out the reward from the coinbase — an imaginary mine containing all possible Bitcoins. Bitcoin appeared on January 3, and slowly ramped up in popularity over the next few years. Because these GPU units were inexpensive and good at handling complex equations, you could squeeze a few hundred megahashes per second out of them resulting in a few Bitcoins a week.
For a while miners were tooling along, pumping out Bitcoins and sharing tips and tricks for maximizing their setups. Bitcoin mining was a hobby. In April Satoshi was gone. Two years after pressing the start button, Bitcoin was steaming along under its own power. Exchanges rose and fell — the most famous one being Mt. Gox in Tokyo, Japan. Gox was originally a Magic: The Gathering Online Exchange M.
Gox deals in about a million Bitcoin a month. GPU mining worked well for a while but, thanks to the natural inclination of the miner to add more and more power, the average gain from a few more megahashes fell exponentially. As single GPU mining fell to parallel mining the speeds seemed to explode — along with energy usage. Rigs that could mine a few Bitcoins a month were now mining a few Satoshis — the miniscule parts of the Bitcoin after the decimal point and the electricity need by GPUs was frighteningly wasteful.
In the end you spent more on the hardware and energy than you could ever sanely mine. First users tried field-programmable gate array machines — chips that could be specially programmed after manufacture to do nearly anything. Then, in , FPGAs were outpaced. Bitcoin rose in notoriety thanks to the rise of Silk Road and the Cyprus economic crash. Accounts that once were worth a few dollars exploded and early users cashed out.
A number of folks I talked to described selling their Bitcoin and buying gold bars, cars, and fancy watches. They were either further compressing their wealth into relatively non-volatile investments or just having fun. It was an arms race. Heavier iron pops up on the forums and Bitcoin fan sites with alarming regularity. Other manufacturers opened up shop offering massive speeds and close up almost immediately — taking preoders with them. One company, Terrahash closed up suddenly in September , writing: We are trying to return as many components as we can, and as soon as we get more money back, we will send additional pro-rated payments to each order.
Customers are not responsible for the risks you took. The instant a new batch of mining tools hits the streets the total processing power of the Bitcoin hive mind rises. When KNC released its product the total power of the network went from 1 petahash per second to 2 petahashes per second. Many expect the network to hit 3 petahashes in the next month. As a measure of pure computing power the Bitcoin mining system — the actual number of machines blasting away at each block — has exploded… over and over again.

With Valley investment and worldwide interest — especially as a medium of exchange — many users are moving towards hosted solutions. You own the machines outright in 59 months. Rowan Alter, VP of sales at Leasebit, sees the hosted model as the only way to fly.
Where can mining go next? All indications point to large farms where users lease out powerful machines or, barring that, the entrance of large, well-heeled banks that simply continue the ASIC race at a much higher scale.
As the difficulty increases the resulting firepower needed to squeeze out a single Bitcoin will raise exponentially. After years of easy returns and rising prices, Bitcoin mining has hit a point where it is all but futile to try to mine at home. Funds like Coinlab are busy building Bitcoin data centers like Alydian where massive banks of ASICs run 24 hours a day, seven days a week.
Not unlike the early Internet, Bitcoin is growing slowly and then all at once. About as far as you can get from Jakarta, another miner was blasting away at the block chain.
After overclocking it, the fans ran on full blast at all times, and there was a constant hum in my room. The box, a nondescript metal enclosure with three massive fans containing some of the fastest, single-purpose computing circuitry available to consumers, is a strange thing.
But he was amazed at the power the Avalon afforded him. Bryce Durbin ; Infographic: Welcome to the Bitcoin arms race. Things are just getting warmed up. And so the arms race began.
