Bitcoin Mining Hardware
The best Bitcoin mining hardware has evolved since 2009
At first, bitcoin mining hardware used their central processing unit (CPU) to mine, but soon this wasn’t fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work.
During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining hardware were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection.
FPGA miners used much less power than CPU’s or GPU’s and made concentrated mining farms possible for the first time.
Advance & Best Bitcoin Mining Hardware
Two best Factors to determine the best bitcoin hardware miner is the cost and less electricity consumption.
Below are the some faq about the bitcoin mining hardware
What is mining?
Mining is the process of spending computation power to secure Bitcoin transactions against reversal and introducing new Bitcoins to the system.
Technically speaking, mining is the calculation of a hash of the a block header, which includes among other things a reference to the previous block, a hash of a set of transactions and a nonce. If the hash value is found to be less than the current target (which is inversely proportional to the difficulty), a new block is formed and the miner gets the newly generated Bitcoins (25 per block at current levels). If the hash is not less than the current target, a new nonce is tried, and a new hash is calculated. This is done millions of times per second by each miner.
Is mining used for some useful computation?
The computations done when mining are internal to Bitcoin and not related to any other distributed computing projects. They serve the purpose of securing the Bitcoin network, which is useful.
Is it not a waste of energy?
Spending energy on creating and securing a free monetary system is hardly a waste. Also, services necessary for the operation of currently widespread monetary systems, such as banks and credit card companies, also spend energy, arguably more than Bitcoin would.
Why don’t we use calculations that are also useful for some other purpose?
To provide security for the Bitcoin network, the calculations involved need to have some very specific features. These features are incompatible with leveraging the computation for other purposes.
How can we stop miners from creating zero transaction blocks?
The incentive for miners to include transactions is in the fees that come along with them. If we were to implement some minimum number of transactions per block it would be trivial for a miner to create and include transactions merely to surpass that threshold. As the network matures, the block reward drops, and miners become more dependent on transactions fees to pay their costs, the problem of zero transaction blocks should diminish over time.
How to compare Bitcoin miners
Keep in mind that in order to see how profitable you can be with any Bitcoin miner you’ll need to make some calculations based on your electricity cost, the Bitcoin exchange rate and the increase in difficulty throughout time. Since not all of these variables are knows you will have to guess some as best as you can.
