What is Cryptocurrency mining? What is an ASIC miner? How does ASIC miner work? To connect the dots – mining in the world of cryptocurrencies frequently uses application-specific integrated circuits (ASICs) that are specialized hardware developed and regularly improved by companies such as Bitmain and Halong Mining, to solely mine Bitcoin or other cryptocurrencies.
Put simply, ASIC mining rigs were created to increase cryptocurrency miners' hash rates as an attempt to secure more block rewards in the form of cryptocurrencies distributed. Let’s dive more into it:
What Is An ASIC Miner?
As its name suggests, application-specific integrated circuit (ASIC) miners are integrated circuits created to serve a specific use case, targeted at performing a particular computing task. As opposed to general-purpose circuits such as the CPUs that power our computers and mobile devices, ASICs are computerized devices designed for the sole purpose of mining cryptocurrencies that are created through proof-of-work consensus algorithm.
How Does ASIC Miner Work?
Proof-of-work mining in cryptocurrencies involves performing a myriad of hashing functions in an attempt to find a solution for a sort of mathematical problem. Whichever miner solves the problem first by producing a valid hash output, is granted the right to validate the next block of transactions that subsequently awards him with a certain amount of the blockchain’s native cryptocurrency as the block reward.
Theoretically, any computer can be used to solve these puzzles. However, because proof-of-work mining is essentially a race between miners, the ones with a greater hash rate (calculations per second) are more likely to solve the puzzle first. This means that using ASICs to mine Bitcoin or other proof-of-work cryptocurrencies is much better than using a general-purpose piece of hardware such as a GPU card, since the job of an ASIC is to perform as many hashing functions per second as possible.
Though, ASIC miners are designed for only a single hashing algorithm, which limits which cryptocurrencies you can mine per rig. For example, Bitcoin is mined through the SHA-256 algorithm while ETHereum is mined through ETHASH. So you would need an ASIC miner for SHA-256 and a separate rig to mine ETHASH if you wanted to mine both.
Considerations of ASIC Miners
Although ASIC miners can be highly efficient, being restricted to a particular use case or even specific cryptocurrency easily deems them completely useless for doing anything else. Moreover, the speed of technological advancements in the cryptocurrency space brings new ASIC models that quickly render older designs completely uncompetitive.
There is also a strong argument with regards to the centralization of mining power caused by ASICs. On the one hand, they provide the essential hashpower needed for securing and verifying blockchains. But on the other hand, they also centralize the power of mining into the hands of a few mining companies who can afford to buy thousands of ASICs to set up and run large mining farms and mining pools, resulting in any solo mining attempts being completely unprofitable from the start.
Closing Thoughts
Without a doubt, ASIC miners fill a gap in the market where there are simple computing tasks that don’t require the financial and computational overhead that a general-purpose CPU would bring to the table. An ASIC can be used as a much simpler and efficient alternative (both in terms of cost and energy) in those circumstances.
We hope that this article has provided you with some light on “how does ASIC miner work” and if you ever do decide to embark on cryptocurrency mining yourself, you can always refer to this article that highlights a few considerations that you should be taking into account in addition to weighing the pros and cons at the end of the day.
