Are you looking to get into the world of cryptocurrency mining but don’t know where to start? Look no further than CPU mining!

CPU mining, short for central processing unit mining, is the process of using a computer’s processor to mine for digital currencies.

This method of mining has been around since the early days of Bitcoin and is still a popular choice for many miners today.

Unlike more advanced methods such as GPU or ASIC mining, CPU mining can be done using just a regular computer and does not require any specialized equipment.

In this blog post, we will take a deep dive into the world of CPU mining. We will cover the basics of what it is and how it works, as well as the pros and cons of using this method.

We will also provide some tips and tricks for those looking to start their own CPU mining operation.

What is Crypto Mining?

Crypto mining is the process of using computer hardware to perform complex calculations to validate transactions on a blockchain network.

The miner who successfully validates a block of transactions earns a reward in the form of cryptocurrency.

These equations, also known as cryptographic hashes, are used to secure the integrity of the blockchain. This ensures that previous transactions cannot be tampered with.

Miners compete to be the first to solve these equations, and the one that does earns a reward in the form of cryptocurrency.

The process of crypto mining also helps to confirm the validity of transactions and prevent double-spending.

What is CPU Mining?

CPU mining refers to the process of using a computer’s central processing unit (CPU) to mine cryptocurrency.

This method involves using software that harnesses the power of the CPU to solve complex mathematical equations. These are used to validate transactions on a blockchain network.

In return for their computational power, miners are rewarded with a small amount of the cryptocurrency they are mining.

However, CPU mining is not as profitable as using specialized mining hardware such as ASICs, because it is less efficient and slower.

How does CPU mining work?

The process begins by downloading a mining software program that is compatible with the specific blockchain network being mined.

This software will connect the miner’s computer to the network and begin the process of solving hashes.

Once connected, the miner’s computer will begin to receive a stream of transactions from the network.

The miner’s software will then take these transactions and bundle them together into a block.

The computer or device will then begin to solve the complex cryptographic puzzle associated with that block.

The miner’s computer will use its CPU to perform complex mathematical calculations in order to find a solution to the puzzle. This process is known as hashing and can take a significant amount of time and computational power to complete.

Once a solution is found, the miner’s computer will broadcast the solution to the network for validation.

If the solution is valid, the miner’s computer will be rewarded with a certain amount of cryptocurrency for its efforts. This reward is known as a block reward and is paid out in the cryptocurrency being mined.

Pros & Cons of CPU Mining

  • Graft (GRFT)

The profitability and difficulty of mining these cryptocurrencies can vary depending on the current state of the network, the number of miners participating, and other factors.

Some cryptocurrencies are developed to be ASIC-resistant, making CPU mining a viable option for them.

The Monero team, for instance, is still actively working to prevent ASICs from being used to mine the cryptocurrency.

They even created a hard fork to ensure that CPU mining would always be the only option to create new XMR coins.

How to Increase Profitability in CPU Mining?

Here are a few ways to potentially increase profitability in CPU mining:

  1. Join a mining pool: Joining a mining pool allows you to combine your mining power with other miners to increase your chances of finding a block, and thus earn more rewards.
  2. Optimize your computer’s performance: Overclocking your CPU and memory, as well as optimizing your operating system for mining, can help to increase your mining speed and thus increase your profits.
  3. Monitor the network’s difficulty: Different cryptocurrencies have different network difficulty levels. This affects the time it takes to find a block and the rewards earned. Monitor the difficulty levels of the cryptocurrencies you are interested in mining to identify opportunities to increase your profits.
  4. Mine multiple currencies: Mining multiple currencies simultaneously can help to increase your overall profitability by diversifying your income streams.
  5. Keep track of your costs: Keep track of your electricity costs, as well as any costs associated with maintaining and upgrading your mining equipment.

History of CPU Mining in Bitcoin Development

Back in the early days of Bitcoin, mining was like a wild west gold rush. Anyone with a computer and an internet connection could join in on the fun and potentially strike it rich.

The first miner to hit the jackpot was none other than Satoshi Nakamoto (the mysterious creator of Bitcoin) who mined the first 50 Bitcoins using the humble CPU chip in his PC, marking the birth of the Genesis Block.

The consensus approach used in CPU mining was “one processor, one vote” as proposed by Satoshi in his 2008 article “Bitcoin: A Peer-to-Peer Electronic Cash System”.

But as time passed, this approach was no longer upheld by Bitcoin, and only a few altcoins still allow for CPU mining.

It was a time when mining was less competitive, and it was relatively easy to earn rewards.

In 2010, you could mine hundreds of Bitcoins with an Intel Pentium CPU, but as more and more miners joined the network, the competition grew fierce.

Miners discovered that the profits from mining outweighed the expenses of power and equipment depreciation.

But as the network grew, the algorithm complexity increased, making the detection of transactions a time-consuming task.

This led to the rise of GPU mining and the fall of the good old CPU mining days.

How to Choose the best CPU Mining Hardware?

These are the key factors to keep in mind when choosing the best CPU for mining.

Just like buying a car, you want to strike a balance between performance, power consumption, price, and compatibility to find the perfect fit for your mining needs.

Hash rate

Think of this as the horsepower of your CPU. The higher the hash rate, the more calculations it can perform per second, and the more efficient it will be at mining.

So, you want to look for a CPU with a high hash rate if you’re serious about mining.

Power consumption

This is an important factor to consider because mining can be a power-hungry process.

A CPU with low power consumption will save you money on electricity in the long run, so you want to look for one with a low power draw.


You don’t want to break the bank on your CPU, so you’ll want to make sure that the one you choose fits within your budget.


Not all CPUs are created equal and some are not compatible with certain mining software. So, make sure to check that the CPU you’re considering is compatible with the software you plan to use.

Clock speed

This is like the RPM of your CPU. The higher the clock speed, the faster the CPU will be. You want to look for a CPU with a high clock speed if you want to mine quickly.

Core count

The more cores a CPU has, the more processing power it has. So, if you want a CPU that can handle multiple tasks at once, you’ll want to look for one with a high core count.

Cooling system

Mining generates a lot of heat, so you’ll want to make sure your CPU has a good cooling system. This will help prevent overheating and keep your CPU running smoothly.


This stands for Thermal Design Power, and it’s the maximum amount of power the cooling system needs to dissipate. You want to look for a low TDP as it means less power consumption.
