Council Post: An Overview Of Mining: CPU, GPU And ASIC

By Ibrahim Alkurd, CEO of New Mine, a blockchain mining {hardware} & software program firm, and a associate at Lavaliere Capital, a digital asset hedge fund

A blockchain is a decentralized database of transactions that everybody on the community can see. The community consists of many computer systems that confirm transactions and add them to the blockchain ledger; this course of is called blockchain mining. The computer systems that conduct blockchain mining are rewarded with cryptocurrency, a digital type of forex designed to work as a medium of change.

I lined what makes the blockchain revolutionary in a previous Forbes article. In this piece, I’ll share an in-depth have a look at the blockchain mining course of. 

Proof Of Work (PoW) Versus Proof Of Stake (PoS)

Blockchains fall into two classes, PoW and PoS. Bitcoin, the primary ever cryptocurrency, runs on a PoW consensus mechanism. This is a type of arithmetic known as cryptography. Cryptography makes use of very troublesome mathematical equations that may solely be solved by computer systems. PoS, the opposite consensus mechanism, was first adopted by a blockchain venture often known as Peercoin. In PoS blockchains, no blockchain mining is completed.

In this text, I shall be specializing in the PoW blockchains as a result of these are those that require blockchain mining. A variety of laptop tools can be utilized for blockchain mining, nevertheless it typically falls into three classes: CPU, GPU and ASIC. The kind of laptop tools that you should utilize is decided by the blockchain that you just need to mine.


CPU stands for central processing unit. It is taken into account the mind of a pc as a result of it controls the operations of all elements. CPUs perform all varieties of knowledge processing operations; with out one, a pc can’t work correctly. In the early days of Bitcoin, you possibly can mine it in your CPU. As mining grew to become extra aggressive, this was not possible. However, there are nonetheless different blockchains that may be mined utilizing a CPU in the present day, corresponding to Loki and Nimiq.

(Full disclosure: My firm holds Bitcoin, Ethereum, XRP and different cryptocurrencies.)


GPU stands for graphics processing unit. GPUs are extra highly effective than CPUs in executing some very particular features. GPUs are supposed to be efficient at doing huge quantities of calculations. This characteristic makes them effectively suited to mining sure blockchains, corresponding to Ethereum. Although it’s technically attainable to mine Ethereum utilizing a CPU, it’s discouraged. GPUs are far simpler for mining Ethereum and different cryptocurrencies corresponding to Ravencoin and Beam.

There are completely different fashions of GPUs. Websites corresponding to WhatToMine help you enter completely different GPU fashions and estimate which would be the most worthwhile cryptocurrencies so that you can mine.


An ASIC is an application-specific built-in circuit. An ASIC is a chip that can be utilized for one objective solely. It was once attainable to mine bitcoin utilizing a CPU/GPU. But this modified because it received extra aggressive. Today, Bitcoin is mined utilizing ASIC chips. Litecoin is one other widespread cryptocurrency that’s mined utilizing ASIC chips.

The majority of large-scale blockchain mines are working ASIC machines. Because these machines are objective constructed, they show to be simpler and dependable at mining.


The blockchain mining panorama has modified drastically over the previous few years. Today, there are literally thousands of blockchains that may be mined utilizing a CPU, GPU or ASIC. This could be a advanced area to navigate, particularly for freshmen. When contemplating blockchain mining for your self or your organization, do your due diligence and seek the advice of with specialists within the area with the intention to keep away from frequent pitfalls.

Blockchain mining has grown to change into a multibillion-dollar business, and it’s solely persevering with to develop. More corporations are coming into the area and innovating on this thrilling area.
