While cryptocurrencies have gained tremendous popularity in recent years, many people are still unfamiliar with the process that underpins them: crypto mining.
In this blog, we'll provide an overview of how crypto mining works, explain key concepts like proof of work, discuss the basics of mining different cryptocurrencies, and address common questions about rewards, difficulty, and the importance of mining overall.
By the end, you'll have a solid foundation to understand this integral process that secures blockchain networks. Let’s start exploring the basics of crypto mining!
Crypto mining is the process by which new cryptocurrency coins are entered into circulation and transaction records, known as blocks, are added to the blockchain.
Most cryptocurrencies use a proof-of-work (PoW) system where miners compete to solve complex cryptographic puzzles in order to validate transactions and earn new coins as rewards for their computational power.
The first crypto miner to solve the puzzle announces their new block, miners verify it's valid, and the transactions are recorded immutably on the blockchain for all to see, with newly minted coins added to the winner's crypto wallet.
While processing blockchain transactions, miners also confirm the accuracy of account balances and the legitimacy of token transfers on the network. Their work keeps the blockchain flowing.
Proof-of-work is the mechanism that underpins cryptocurrency mining. By requiring miners to expend computational effort, PoW deters attackers from rewriting transaction histories or "double spending" cryptocurrency.
Before adding transactions as immutable blocks on the blockchain, it makes sure that the majority of network nodes in the blockchain have approved them. As a consensus mechanism, proof of work aims to keep blockchain secure.
Beyond validating transactions, mining cryptocurrency also serves to introduce new tokens into circulation, controlling the cryptocurrency's supply. If you want to learn more about tokens, you can check “tokens and tokenization in blockchain”.
For example, each time a Bitcoin block is added, a preset number of BTC is awarded to the solver as a reward. Over time, less and less new crypto will enter the network as blocks take increasingly more work to solve.
Miners are incentivized to participate through block rewards and fees from transactions. Currently, Bitcoin miners earn 6.25 BTC per block, or around $240,000 at current prices.
On top of block rewards, miners also collect fees from transactions included in their blocks. These fees make mining some coins with lower rewards still profitable.
By requiring massive computational power to participate, PoW makes the blockchain technology very secure against hijacking and forks. The security comes from the distributed consensus of thousands of independent miners.
As more powerful ASIC miners join, the network difficulty automatically adjusts to keep block times consistent, preserving security as the competition heats up.
Today, around 200 hashes per second of hashing power secure the Bitcoin network, equivalent to all supercomputers on Earth combined.
Only a quasi-government would be capable of overpowering this decentralized hashrate. However, increased centralization of mining does pose security risks, like censorship.
Therefore, there are different types of consensus mechanisms that aim to eliminate this need for energy, such as proof of stake, proof of authority, and types of proof of stake. If you need a comparison to see the distinctions in detail, you can check out “Proof of Work vs. Proof of Stake.".
To start crypto mining, you'll need specialized mining hardware, like ASIC miners, that can hash through random numbers as fast as possible.
Once you have your mining rig set up, research coins available to mine and join a mining pool dedicated to that coin. Pools consolidate the hashing power of many miners to increase rewards through shared block finds and fees.
Early cryptocurrency adopters could mine using CPU and GPU on their personal computers. However, the mining arms race led to the rise of application-specific integrated circuits (ASICs) that far outperformed general components.
Today, only the most efficient ASIC miners make industrial-scale mining profitable for major coins. Entry-level ASICs for popular algorithms run $500–5000, while cutting-edge miners run tens of thousands. Therefore, it is crucial to have a good hardware system to mine cryptocurrency.
As challenges increased, the only way for smaller miners to remain profitable was to join large mining pools. Pools consolidate resources, splitting block rewards proportionally based on each miner's hashrate share.
The largest Bitcoin pools control over 50% of the network hashrate. Popular Ethereum Classic pools include Ethermine and F2Pool. Choosing the right pool is key to profitability.
Without crypto mining, public blockchains would not achieve distributed consensus or issue new tokens into circulation. Miners play a vital role in securing these networks through proof-of-work. Additionally, mining hardware manufacturers are advancing computer technology through competition.
While energy-intensive, mining also makes blockchain-censorship-resistant monetary and record-keeping systems independent of any central authority. The EURK takes advantage of this model by being a securely audited euro stablecoin on multiple blockchains and available on ERC20.
The time required to mine one crypto varies greatly depending on the cryptocurrency and mining equipment used. As an example, it would take the average desktop PC over 100 years to mine a single bitcoin at today's difficulty.
However, an industrial-scale ASIC miner could theoretically mine one every 10 minutes by being the first to solve each new block puzzle. Altcoins with lower crypto market caps are generally easier to mine initially, but difficulty rises with popularity.
Due to the computational power needed, mining is indeed energy-intensive. The Bitcoin network alone consumes more electricity annually than countries like Switzerland or Argentina. Some estimate its energy use is comparable to Google's.
As top crypto mining nations lack green policies, this reliance on fossil fuels for difficult PoW algorithms raises sustainability concerns. However, innovative consensus mechanisms, such as PoS, and renewable energy adoption could help address this in the future.
Only the most efficient miners using top-end ASICs in regions with cheap electricity are likely to consistently profit from mining major coins like Bitcoin at this stage. However, smaller miners can still benefit from mining alternative coins or joining a mining pool.
Consider factors like upfront costs, difficulty projections, coin viability, and future rewards when deciding if mining is right for you. Researching different cryptocurrencies is important when starting out in crypto mining to determine the best crypto mining opportunities available.
Given the uncertain economics, many regard mining as more of a long-term investment in the sector than a short-term income generator.
With rising competition in major PoW networks and growing calls for more eco-friendly blockchains, the future of cryptocurrency mining remains unclear. Meanwhile, projects like EURK offer businesses and consumers access to stable digital assets supported by transparent auditing and reserve holdings.
As cryptocurrency sees wider adoption, its underlying technologies will continue their evolution in tandem. With reliable and efficient stablecoin solutions like EURK, innovation can progress while upholding the core principles of security and decentralization.
Crypto mining serves to validate transactions and introduce new coins to public blockchains through the proof-of-work mechanism. By requiring immense computing power, PoW deters attacks and decentralizes consensus.
Large mining pools that use ASIC rigs globally now secure major networks. While industrial mining certainly demands large amounts of energy, it also drives advances in computer technologies and keeps blockchains free of centralized control.
As cryptocurrency finds applications, improvements to consensus methods may allow mining to continue powering blockchains in a more sustainable manner.
Projects like EURK leverage these open infrastructures, providing a gateway for mainstream use of digital assets through its transparent and stable peg to the euro.
