Mining equipment is a fundamental feature of the success of the bitcoin network because these machines determine whether or not it is profitable for miners to do what they do — that is, process the calculations needed to embed blocks of transactions on the blockchain.
While somewhat overlooked, the history of bitcoin mining equipment is also a key explanation for why the activity of mining has evolved over the years into a multi-billion dollar industry. The mining industry continues to evolve today, though there are signs to suggest its development is slowing down.
Subscribe to Blockchain Bitesour daily update with the latest stories. Below we take a look at the complete history of bitcoin mining technology, and where innovations could be heading next.
What is an ASIC Bitcoin Miner?
He was able to create bitcoin blocks using an average personal computer. Computers used to browse the internet, launch Microsoft Word and a number of other countless applications all contain what is called a central processing unit CPU. These devices control how commands on a computer are processed and executed. Hardware needed to mine new coins evolved over time as new miners joined the Bitcoin network and started to compete for block rewards.
Bitcoin mining difficulty vs. According to cryptocurrency data provider Coin Metrics, bitcoin market price then appreciated in July to around 8 cents. By the time the bitcoin price reached 10 types of quick earnings in Octoberthe first mining device leveraging graphics processing units GPUs was developed. Originally built for gaming applications, GPUs excel at computing simple mathematical operations in parallel, rather than one at a time, in order to generate thousands of time-sensitive image pixels.
These devices can also be re-programmed to compute other mathematical operations such as the ones required to mine new bitcoin.
What to Consider When Selecting Bitcoin Mining Hardware
Enclosure containing GPU cryptocurrency mining machines. Bitcoin mining equipment efficiency gains were quickly overshadowed the following year, inwhen field programmable gate arrays FPGAs were also re-modeled to mine bitcoin.
However, these devices are more labor-intensive to build. FPGAs require configuration on both a software and hardware level, meaning bitcoin mining equipment devices must be programmed to run customized code, as well as architected bitcoin mining equipment run that code efficiently. It is the ability to adjust hardware components on an FPGA that makes these types of devices better optimized for bitcoin mining than a GPU.
7 of the Best Bitcoin Mining Hardware of 2018
ASIC mining The third major innovation to bitcoin mining likely required the largest amount of dedicated resources, time and development to achieve. Rather than repurposing the software and hardware parameters of existing machines, efforts to create an entirely new machine that would only mine bitcoin finally paid off. Ina China-based computer hardware manufacturer called Canaan Creative released the first set of application-specific integrated circuits ASICs for bitcoin mining.
This meant that all hardware and software components of these ASIC devices came pre-designed and optimized to compute strictly those calculations necessary to create new bitcoin blocks. The efficiency gains from ASICs could not be matched bitcoin mining equipment any of the more general purpose devices that preceded it. One of the most noticeable developments in ASIC mining technology since has been a steady reduction in chip size.
Bitcoin Mining Hardware Comparison
The size of ASIC chips which started off at a size of nm in has shrunk considerably to be as small as 7nm in the latest hardware models. Without a radical new ground-breaking technology, bitcoin miners will soon stop competing primarily on the basis of hardware and equipment as was the case for the past decade.
The significance of chip size comes back to mining efficiency. The wider the surface of an ASIC chip, the larger its communication channels and therefore the more electricity required to transmit data on its surface.
