What is a Cryptominer & How Does it Work?

Crypto mining is how many cryptocurrencies, including Bitcoin, process transactions and mint new tokens. Let's delve into the complex world of cryptocurrency mining, cover how the process works and assess whether the rewards on offer outweigh the risks involved with such a novel industry.

What is a cryptominer?

What is cryptocurrency?

Cryptocurrency is a type of digital money. Its value is derived from the fact that the only way to acquire cryptocurrency is to have a computer work on solving very complicated mathematical equations. Once these equations are solved to a certain point, an amount of cryptocurrency is then "owned" by whomever did the solving. This process is called "mining" for cryptocurrency.

What is cryptocurrency mining?

A cryptominer can be used legitimately and illegitimately to mine cryptocurrencies. When used illegitimately on your computer without your awareness, seek to hijack idle processing power to mine cryptocurrency and make the cybercriminal rich.

So what is cryptomining and how does it relate to your PC's safety? Well, in order to create cryptocurrency, users must loan their computer's processing power to "mine" the coins by solving complex math equations. This is the primary purpose of a cryptominer.

Why do crypto miners hack other computers and what are the consequences?

Hackers seek to maximize potential profits by leveraging the computing power of as many devices as they can, even ones they shouldn't have access to.

So, how can a cryptominer impact the state of your PC? Aside from hacking into your digital currency, a cryptominer can put a heavy computational load on any computer. This could cause its operation to slow down while the mining is happening. In addition, if a computer mining cryptocurrency continuously, it can significantly increase your electricity bill through your computer's increased electricity consumption.

How does crypto mining work?

Cryptocurrency mining is an achievement of innovation and complexity. While the mining process can be a confusing one, breaking it down into a step-by-step process can prove an enlightening exercise. Here is how mining cryptocurrency works:

  1. Pooling Transactions for Verification:
    Within the crypto world, transactions are grouped into pools that await the attention of a miner. Each of these transactions carry important details accompanied by a processing fee, which attracts miners to knuckle down and get involved.
  2. Forming the Block with Unverified Transactions:
    Cryptominers then begin the arduous process of sifting through the pool of transactions to create a block. This block consists of a collection of unverified transactions. The process for this is similar to assembling the pieces of a puzzle, although miners may prioritize these transactions based on factors including sizes, age or associated fees.
  3. Initiating the Mining Competition:
    With the block in hand, miners embark on a race against time and computational power. Armed with specialized hardware, they tackle a formidable mathematical puzzle. The objective? To unearth a specific number—a nonce—that, when combined with the block's data, yields a unique hash. Now the block has been formed, a race against time begins. Complete with specialized hardware driven by computational power, miners tackle a complex mathematical puzzle. Once completed, the miner will unearth a specific number known as a nonce. When combined with the block's data, a unique hash is formed.
  4. Broadcasting the Solution to the Network:
    Once the miner has cracked the code, they will then broadcast their discovery to the blockchain network, signaling victory and a sense of triumph.
  5. Official Addition of the New Block:
    This euphoria can be short lived however. Validation is required from fellow miners who scrutinize the broadcasted solution to ensure its accuracy. Once enough miners confirm this, the new block is added to the blockchain.
  6. Distribution of Mining Rewards:
    At last, a payday for the miner. Once the new block has been added to the blockchain, the miner stands to reap the rewards which include transaction fees and freshly minted tokens.

Cryptocurrency mining is a complex process that combines both technology and teamwork. However, much like any venture, while the pros are lengthy, there are also a number of drawbacks to be considered.

What are the benefits of cryptocurrency mining?

While crypto mining is largely subjected to negative press, it does retain a number of benefits that can often be overlooked. Here is why it has become such a popular pursuit in recent years:

  • Mining can be very profitable: There are huge financial rewards for those who are able to sustain successful mining ventures, providing a lucrative income stream to those who invest both time and resources into the process. In April 2024 for example, the daily Bitcoin miner revenue was around $65 million!
  • It allows blockchains to operate: Without cryptomining, the entire blockchain ecosystem would break down. Mining serves as the lifeblood of the network.
  • Rewards are efficiently distributed: The equitable reward system of crypto mining is what attracts many in the first place. A fair distribution of wealth is implemented and dependent on those who contribute to the network's security and integrity. Those who do are compensated with transaction fees and newly minted tokens.
  • Supports blockchain security: The decentralized nature of cryptocurrency mining serves to fortify the security of blockchain networks. Through their mining efforts, miners further safeguard the network against potential threats, protecting both transactions and user data.
  • Creates job opportunities: With the rapid progress of digital innovation, crypto mining represents a path to financial freedom while creating new job opportunities, especially in regions with access to affordable electricity and efficient internet connection.

While it may seem that many crypto miners are solely chasing profits, they are also contributing and fortifying a global network that has already begun to revolutionize the way we transact and will continue to do so for years to come.

What are the cons of cryptomining?

While cryptocurrency mining offers enticing rewards, it's not without its share of challenges. Let's delve into some of the drawbacks of crypto mining:

  • High cost: Mining cryptocurrency is an incredibly expensive endeavor. From the exorbitant set up costs in purchasing and maintaining appropriate hardware, to the astronomical electricity bills that are an inevitability, deep pockets are needed to keep up to speed in the crypto mining industry.
  • Decreases lifespan of graphics card: The incessant workload imposed by cryptomining degrades the performance of graphics card and shortens their lifespan significantly. The frequent replacements required are another cost that cryptominers must consider.
  • Volatility of the market: The cryptocurrency market is well known for its volatility. Drastic fluctuations in price are a regular occurrence, making it incredibly difficult for cryptominers to accurately assess profitability.
  • Substantial carbon footprint: The necessary energy required to maintain the relevant machines contributes to a significant carbon footprint. The dependance on non-renewable energy sources has caused debate to rage around the sustainability of the industry.
  • Lack of stable regulatory framework: The regulatory landscape of cryptocurrency is murky at best, lacking a cohesive framework to govern operations. This raises a number of legal and compliance risks for miners, which are important to consider.
  • Security vulnerabilities: Miners are incredibly vulnerable when it comes to hackers. Robust cybersecurity measures paramount, as hacking attempts and malware infections are a frequent occurrence.

While the financial rewards on offer are substantial, the potential pitfalls cannot be ignored. It is imperative that any potential cryptominer carefully weighs up their position prior to diving into the crypto mining industry.
