Cryptocurrency mining is the process of contributing your computer’s processing resources to secure the network consensus on a blockchain while earning cryptocurrency in return. Miners solve complex mathematical equations to verify transactions and add them to the digital ledger. While blockchains that use a Proof-of-Stake consensus mechanism don't need or enable it, mining is essential on Proof-of-Work blockchains like the Bitcoin blockchain to bring new coins into circulation and maintain the blockchain network's integrity and security.
While a mining operation provides a solid mechanism for achieving consensus and preventing abuses, it also has significant disadvantages, such as its negative environmental impact. Additionally, mining requires substantial computational power, energy, and technical expertise, making it a challenging task for beginners.
For example, mining crypto on a blockchain like the Bitcoin network has an exceptionally high barrier to entry. Bitcoin miners must invest in specialized equipment and cover increasingly-high energy costs.

What Is Cryptocurrency Mining?
Blockchain networks that employ a Proof-of-Work consensus mechanism require computational processing power to solve a mathematical problem to mine new coins. Bitcoin (BTC), Litecoin (LTC), and many other blockchain networks use the Proof of Work (PoW) consensus mechanism to produce and validate new blocks of transactions and safeguard the network. Miners spend substantial computing resources to verify and validate transactions and secure the network from potential attacks and malicious entities.
The Proof-of-Work mechanism provides high security and a decentralized method of verifying transactions. It reaches consensus across all the distributed participants without third-party intermediaries and solves the double-spend problem, preventing the network participants from using the same funds more than once. On the flip side, crypto mining has been criticized for being energy-intensive and requiring high transaction fees and expensive equipment.
The blockchain network rewards miners for their efforts in securing the network. Miners compete by solving complex algorithms with mining hardware to win the right to mine the next block. Rewards are given to the first miner to identify a valid solution and confirm their block of transactions. As a result, the procedure is time-consuming and costly, but it compensates for the efforts.
However, the problem with PoW is that a blockchain can be destabilized with a so-called 51% assault. While extremely uncommon, particularly for bigger blockchain networks, a single company or group may theoretically control more than half of the network's computational power. With that much mining power, the attacker can purposely exclude or manipulate the order of transactions, as well as reverse their own transactions.
Another major concern with cryptocurrency mining is its long-term viability and high costs. Mining cryptocurrency requires significant investment in hardware and electricity. As a result, many miners, especially those that mine Bitcoin (BTC), spend vast quantities of energy. Furthermore, if a miner doesn't have access to mining rigs and affordable power, the mining will rarely be profitable.
What is a Crypto Hash?
Cryptography refers to the rock-solid procedure of safeguarding blockchain transactions through hashes. A hash is required to complete a block's worth of transactions. Miners use their devices to create a "hash" that's randomly generated and has to equal or be lower than the value of the "target hash." The first miner to generate the hash gets rewarded with newly minted coins.
A hash looks like this:
00000000000000000004b79b7967388e022311e5194547644b119d30220ca19p
Each block has its own unique 64-digit hash, and any change to a single transaction will result in a different hash. Furthermore, each block's hash is tied to the previous block's hash. This makes transactions tamper-proof once recorded and the blockchain immutable.
Any attempt to modify anything in a single block would affect the hashes of all following blocks, eventually resulting in a fork or a separate blockchain. Depending on the length of the chain, it may require massive computing power and prove worthless due to being time-consuming and costly.
However, not all forks are caused by flawed individuals; instead, there are also system-generated forks, which may be viewed as updates. For example, the Ethereum London Hard Fork on August 5th, 2021, at 12:33:42 PM +UTC, from block number 12,965,000, was legal. The history of all forks on the Ethereum blockchain can be seen here.
How to Find the Target Hash?
The target hash is a numerical value determined by the network every 2,016 blocks. The aim is to maintain the mining difficulty such that a block is mined every 10 minutes on average. It is the value for which a hashed block header is targeted.
Block headers are 80-byte data strings that act as individual block identifiers. It provides block-specific information such as the bitcoin version number, hash of the preceding block, timestamp, etc.
Therefore, the mining process is nothing more than executing algorithms (for bitcoin mining, the SHA-256 hashing algorithm) to hash the block headers to a number below the target. And the first person to complete the task receives the block prize, similar to winning the lottery.
Mining was simple back in 2009 when you could have mined using your personal computer. However, as Bitcoin gained popularity, its value increased, and more individuals began mining professionally. This has increased the mining difficulty, and to earn the block reward, you now need nothing less than dedicated machines with significant processing capability.
Yet, there are alternatives if you don't want to spend heavily on mining equipment. Let’s go over the various types of mining to understand this better.
Fast Fact
Not every cryptocurrency can be mined since not all utilize a competitive reward scheme.
Types of Cryptocurrency Mining
Here are several types of Bitcoin mining you can engage in:
ASIC Mining
Mining with an application-specific integrated circuit (ASIC). This mining device is designed to mine a particular coin. It’s expensive but has the greatest hash rate, which means it delivers greater mining power.
CPU Mining
Mining with the central processor unit of a computer (CPU). Although this is the most widely available technique of mining cryptocurrency, CPUs lack the mining power of ASICs and GPUs. As a result, revenues from CPU mining are small.
GPU Mining
Mining with the help of one or more sophisticated graphics processing units (GPUs), often called graphics cards. They, too, give significant mining power, albeit at a relatively hefty initial cost.
Mining Pools
Groups of miners who work together to mine cryptocurrency and share block rewards. Miners pay a modest fraction of the block rewards as a pool fee. Combining your hashing power with a mining pool will earn more than mining alone.
Cloud Mining
Paying a company to mine cryptocurrency on your behalf using their own mining equipment. A contract is required for cloud mining, and the conditions almost usually benefit the company over the miner. In essence, you invest in mining operations managed by another company and reap the rewards based on the hash rate purchased with the contract.
Solo Mining
Mining on your own. Earning block rewards in this manner is far more complex, leaving mining pools as your best option.
Ultimately, the best type of mining is determined by the cryptocurrency and the amount of money you can afford to invest. You need a graphics processing unit (GPU) or an application-specific integrated circuit (ASIC) to set up a mining rig. In most circumstances, ASIC mining or GPU mining with a mining pool is the best choice.
