How does Bitcoin Mining Work?

Bitcoin mining involves verifying transactions before adding them to the blockchain. Since Bitcoins are decentralized and no third party like banks governs the transactions, miners validate transactions to prevent any fraud.

However, Bitcoin mining is a complex process that demands specialized equipment to solve cryptographic puzzles. Miners will be rewarded with freshly minted new Bitcoins based on their contributions like computing power, time and energy in validating transactions.

Let’s decode the comprehensive Bitcoin mining process and better understand it.

1. Setting up the Mining Hardware

The first and foremost thing you will need for Bitcoin mining is specialized mining equipment. Since Bitcoin mining demands excessive energy, it is nearly impossible to mine Bitcoins with your regular computer.

ASICs (Application Specific Integrated Circuits) are advanced mining machines that come with excellent hash rate, energy efficiency and computing power, enabling you to solve puzzles faster and mine blocks sooner.

These ASICs are highly sophisticated machines that are finely programmed for the specific mining algorithm. For instance, Bitcoin ASIC miners are programmed for the Bitcoin mining algorithm, SHA-256. Thus, miners can mine their intended cryptocurrency efficiently despite the network difficulty.

The setting up process of any ASIC is straightforward. So, for any ASIC miner, be it a Bitcoin miner, Zcash miner or Kaspa miner, the setting up process is more or less the same.

All you need is a dedicated power infrastructure and a wired network connection, as ASICs demand more power and do not support wifi. You can read our setup blog to get a better understanding of the ASIC setup process.

2. Installing the Mining Software & Crypto Wallets

Once you have finalized the mining hardware and done with the power infrastructure suitable for that hardware, the next step is to choose the right mining software. Multiminer, XMR Miner, and CG Miner are some of the most popular Bitcoin mining software used by Bitcoin miners.

Almost all Bitcoin mining software is available online, and you can download it for free. Now that your mining hardware, software and power setup are ready, you’re all set to mine Bitcoin. However, where will you store your rewards, Bitcoins? You will need a dedicated Bitcoin wallet to store and transfer Bitcoins.

3. Joining a Bitcoin Mining Pool

So, now that you’ve got a dedicated Bitcoin mining setup, why join a Bitcoin mining pool rather than solo mining? Besides the mining infrastructure, Bitcoin mining demands some technical expertise.

Mining pools facilitate that by enabling miners to share their computing resources and their knowledge with fellow miners in the network, increasing the chances of solving blocks and successful mining of new Bitcoins. And, of course, more miners mean a more reliable and secure network.

4. Start Mining Bitcoins

Bitcoin mining is a technical process that requires miners to solve complex algorithms. Let’s see the process in detail. The Bitcoin mining algorithm, SHA-256, generates a random hash and adds another number to it known as nonce.

Nonce (number used only once) is a four-byte randomly generated number. Miners use this nonce to find the hexadecimal number called hash, which is less than or equal to the network’s target.

Nonce always starts with zero when a miner begins the mining process. After every attempt, it changes to 1, 2,3, and continues until the miner finds the hash. The hash and nonce generated should be less than or equal to the target hash, or else the attempt fails. The miner who first solves the puzzle gets rewards, and a new block is created.

5. Proof of Work (PoW)

Bitcoin mining follows the Proof of Work (PoW) consensus mechanism, which demands a large amount of energy and computational power to solve puzzles and achieves the hexadecimal number equal to the target hash. Here, the work done is validating transactions. Thus, it is called Proof of Work.

6. Confirmation

The block confirmation is again an extensive process. Since each block contains the hash of the previous block, any change in the block will impact the other block’s hash as well. This feature enhances blockchain security.

Now, the confirmation for solving the blocks is achieved until it reaches around five blocks later. Though one can alter the block’s information until it reaches six validations, altering it after that is extremely unlikely since the network is decentralized.

7. Rewards

Miners who successfully validated the block receive newly minted Bitcoins as rewards. The rewards are not fixed and keep changing as Bitcoin halving occurs every four years, that is, after 210,000 blocks are mined.

For instance, miners received 50 Bitcoins for mining a block in 2009. The block reward was halved, and they received 25 Bitcoins in 2012. In the consecutive halving events, the reward was reduced to 12.5 and 6.25. In the upcoming Bitcoin halving event, the reward will decline to 3.125.

Besides the rewards, miners will also receive transaction fees. It is expected that Bitcoin will reach the maximum limit of 21 million in around 2140. Miners will get payments for processing transactions, which network users will pay, which will keep the Bitcoin network going.

Cost Associated With Bitcoin Mining

Bitcoin mining is a technological process that demands specialized mining infrastructure and power setup. Additionally, since Bitcoin mining is energy-intensive, it would shoot up your electricity bills.

So, if you’re considering Bitcoin mining, you may need to be prepared for the following costs.

1. ASIC Miner

Crypto mining requires specialized devices called ASICs, which are optimized for the specific cryptocurrency’s mining algorithm. Bitcoin miners are fine-tuned for the SHA-256 algorithm with a high hash rate, enabling miners to mine Bitcoins successfully.

These advanced Bitcoin miners can cost you significantly, which you should consider before stepping into professional Bitcoin mining.

2. Electricity Costs

Most ASIC miners that help you with crypto mining will need high power. Thus, it is no wonder your electricity consumption will drastically increase. Hence, consider the electricity charges in your locality before buying a Bitcoin miner.

3. Cooling Costs

Since Bitcoin miners release large amounts of heat, you may need to invest in additional cooling systems like air conditioners, fans, etc, especially if you live in tropical places.

4. Internet and Networking Costs

You will need a steady high-speed internet connection to connect your miner to the Bitcoin network. Consider the internet costs and the cost of additional network devices that you may need.

5. Mining Pool Fees

Bitcoin mining pools charge a small percentage of their rewards as mining pool fees. Ensure you enquire about the service charges before partnering with the mining pool.

6. Taxes

You may be subject to taxes on your mining earnings depending on your country’s laws. Hence, it is crucial to understand the tax implications in your country before indulging in Bitcoin mining.

Incentives for Bitcoin Miners

Bitcoin mining demands miners use advanced ASICs with high computational power to solve complex algorithms to validate transactions and mine new Bitcoins. So, what will miners get in return for all their efforts, time, and costs? — incentives.

So, how are the incentives calculated? Miners receive newly minted Bitcoins as rewards and transaction fees as incentives.

Simply put,

Bitcoin Miners Incentives = Block Rewards + Transaction Fees

As discussed earlier in the blog, the Bitcoin halving will significantly impact the profitability of Bitcoin miners in the future. However, miners should wait and watch.

Factors Determining Bitcoin Mining Profitability

Bitcoin mining profitability depends on various factors, some controllable while others are not. Here is the list of factors that impact Bitcoin mining profitability.

1. Bitcoin price
2. Hashrate
3. Mining difficulty
4. Number of network participants
5. Electricity costs
6. Mining hardware efficiency
7. Mining pool fees
8. Market trends
9. Regulatory affairs and taxes in your country

The list is endless. Hence, miners should be watchful and do their best to understand the market. That will help them take calculated risks while enhancing their profits and minimizing losses.
