Regular computers were enough in 2009 to mine crypto coins when they first hit the scene! With a decent CPU and a bit of patience, you could actually work wonders back then. The mindset of miners back then was simple: They saw crypto as a new tech experiment and not a pecuniary revolution. As more miners joined the rat race, the competition level increased, and so did the difficulty level. CPUs started to find it difficult to keep up, and GPUs made a grand entry into the scene.

The rise of GPUs

Are you an experienced miner? Then it must be clear to you that CPUs cannot serve your mining purpose in the current times. Miners clearly understood this simple reality, and GPUs started gaining traction. What is the difference between the two? Well, while a CPU is designed for general computing tasks, GPUs are excellent at parallel processing! Mining requires solving cryptographic puzzles, and GPUs ensure an easier and more accurate process in this regard.

In the fall of 2011, mining was totally done using GPUs, which outperformed normal CPUs in all departments. From mining speed, accuracy, and hash rate to power consumption, GPUs were better in all aspects. Casual miners started feeling the pressure of purchasing better hardware to stay in the race as competition increased significantly.

Mining pools were also born with the increase in GPU mining. As an individual miner, you could have felt heightened competition with large-scale operations. What was the solution? Pooling their resources, which increased their chances of earning rewards. There was relatively high accessibility, but a rapid evolution of the industry was noted as well.

Enter the FPGAs

The scourge for better technology in crypto mining is constant, with the community always looking for better alternatives. GPUs were a massive improvement, but due to the quest for rapid advancements and profits, new technologies were being designed. This led to the rise of Field-Programmable Gate Arrays or FPGAs and their adoption by miners.

These FPGAs gained popularity, as they served the basic purpose of mining and were completely programmable to do the same. You could have easily ensured greater efficiency with FPGAs as they could be optimized to perform such tasks with greater efficiency levels. The only drawbacks were higher costs and greater technical abilities to control these devices.

With such massive drawbacks, FPGAs were never a mainstream trend in mining, as a mass of the community was not interested. These devices, however, served the role of a bridge between GPUs and ASICs, the real game changer in the field of crypto mining.

The ASIC boom

Have you heard the term ASIC? If you are a crypto enthusiast, then this is a term that you must have come across multiple times. ASICs or Application-Specific Integrated Circuits changed the entire domain of crypto mining. The basic advantage of ASICs in crypto mining over CPUs, GPUs, and FGPAs is the fact that they are devised to do just one thing, mining cryptocurrency.

Around 2013, the first ASIC miners made news and were an instant hit among the masses. With exponentially more power and less electricity consumption, these miners were highly in demand. What's more! ASIC miners had an insane hash rate, which led to mining becoming an industry-level operation and led to enhanced profitability for the miners at the same time.

Multiple companies started mass-producing ASIC miners owing to their increase in popularity and these gave birth to large-scale mining farms. These farms were established with the goal of mining crypto 24/7 and were generally established in regions that had lower electricity costs as well.

Wondering what happened to GPU mining? Well, it became nearly obsolete, as only some smaller coins are mined using the same even to date. This was a massive shift as small miners were completely out of the competition and casual miners were also out. Either they had to purchase costlier hardware and ASIC miners or leave mining as a whole.

The shift to eco-friendly mining

Concerns about energy consumption rose with ASIC miners, even though they are an extremely efficient option. Sustainability concerns were raised by critics, which was true to an extent as a massive amount of electricity was required for an efficient mining process.

Miners started actively looking for solutions to the problem of sustainability as it was hampering operations significantly. Some mining operations were relocated to places where renewable energy sources were being used to generate electricity. Besides, miners also looked to make use of other innovation models like immersion cooling that helped in increasing efficiency while minimizing energy waste.

What’s more! Some cryptocurrencies took a massive shift from traditional mining models altogether. New concepts like proof-of-stake (PoS) which is a replacement for the traditional model of proof-of-work (PoW) took place. This eliminated the need for mining operations altogether and ensured better sustainability.

The future of crypto mining

Aren't you fascinated by the evolution of crypto-mining machines? From simple CPUs to highly powerful ASIC miners, crypto miners have come a long way. Technological advancements have made all these changes increasingly practical and possible as the future also seems bright.

The future of crypto mining is bound to be more energy efficient and a focus on green mining solutions is inevitable. ASIC miners that are more energy efficient are being developed to meet the sustainability needs that are being projected as a major challenge to mining processes.

At present, large crypto-mining farms are dominating the markets. However, with a shift towards decentralized mining pools, the odds could be easily evened out as a level playing field can be created.

Would you prefer mining GPU coins or ASIC coins? Well, with alternative solutions available, GPU coins are gaining more traction as they are easy to mine and can ensure better sustainability standards as well.

Quantum computing can have an array of impacts on the domain of crypto mining. It can either make sweeping changes for a positive outcome or can render it obsolete in the long run!

With the crypto mining landscape always changing it is not wrong if someone says that innovation in this field never halts. The journey is far from over as you can easily see sweeping changes in the coming years.
