How Bitcoin Mining Works: Explanation and Examples

bitcoin mining

Creating new Bitcoins and putting them into circulation are done through the process of bitcoin mining.

Because it encourages users to enter accurate information into the shared ledger that records transactions and balances on an underlying blockchain network, mining is essential to the operation of Bitcoin and some other cryptocurrencies. Participants in this process known as mining compete for Bitcoin-based incentives.

Although Bitcoin mining has a solid reputation for dependability, it has also come under fire for using too much energy to power the network. The electricity used by Bitcoin alone exceeds that of some entire nations. While some cryptocurrencies have been moving away from mining, Bitcoin is still dependent on it.

Because mining relies on complex cryptography designed to deter fraud and theft, the mining mechanisms can perplex regular users. Powerful, dedicated machines that might cost hundreds or thousands of dollars are often used for Bitcoin mining.

However, mining is necessary for Bitcoin to exist as we know it. The main part of Bitcoin’s “proof-of-work” mechanism is bitcoin mining. It ensures that when someone sends you Bitcoin, the money actually does arrive and prevents thieves from claiming to be the owner of your Bitcoin.

Why Does Bitcoin Need Mining?

You might not have given mining much thought if you only purchased or traded Bitcoin. But since Bitcoin is user-maintained, it’s advantageous for anyone working with it to understand its technological foundations.

Bitcoin, like many other blockchain systems, lacks a central controller and maintains a decentralized ledger of user balances. Bitcoin instead relies on users to keep their own copies of the transaction history ledger. Users reach an understanding about the accuracy of those shared records through a process known as mining.

The network creates enough transactions around every 10 minutes to create a new “block,” which is essentially a collection of transactions that has been tamper-resistant encoded. The miner is paid when they successfully add a new block to the record.

However, mining is more complicated than just looking for fresh transactions and submitting them. Everyone would be able to accomplish it if it were. Bitcoin mining is a costly process that involves solving challenging computational puzzles in order to prevent fraud.

In an effort to be the first to obtain a value that falls inside a specific mathematical range, miners’ computers run cryptographic calculations trillions of times each second. A block can be submitted after this task is successfully completed, and the miner will be paid if the network’s other computers find that it matches their records.

The theory behind this is that mining shifts the economic incentives in favor of miners acting honorably. You might not want to take the chance of losing your prospective return by, say, entering false information about the Bitcoin in your account after investing the time and money to mine a block.

Can anyone mine Bitcoin?

Anyone can participate in the Bitcoin mining process, but your chances of earning a reward are very slim unless you have access to the potent processors known as ASICs (that’s “application-specific integrated circuits”).

When Bitcoin first started, more than ten years ago, using a home computer to mine was not a big deal. However, as Bitcoin’s value has increased, so has competition for the rewards, igniting a race to put ever-faster, more potent mining equipment into operation.

The mining industry has grown to be worth billions of dollars, and the miners who stand the best chance of earning rewards are now those who have warehouses full of ASICs.

Smaller-scale miners have created certain associations known as mining pools to aid them in competing. Users can pool their computing resources under these agreements and then split the profits they make, minus a fee.

How much can you make by Bitcoin mining?

We’ve established that mining Bitcoin is challenging, but hey, you can dream. This Bitcoin mining example might assist illustrate what you would receive if you were to receive a block reward.

The mining rewards for Bitcoin are generally the same every 10 minutes, which is significant to note. Should you be so fortunate, your compensation will depend on whether you mine a block by yourself (unlikely) or in a pool with other miners.

Every time a new “block” is added to the permanent ledger of transactions, Bitcoin pays out a mining reward. The payout decreases with time, but at this time it stands at 6.25 BTC, which in December 2022, when the price of Bitcoin was hovering at $17,000, was worth around $105,000.

Bitcoin miners further make money from transaction fees that are automatically assessed when a cryptocurrency is transferred from one crypto wallet to another. Transaction fees are not predetermined, in contrast to the block reward. They fluctuate according to factors in the network, including the volume of transactions at a particular time.

The size of the reward will fluctuate as new blocks are uploaded to Bitcoin’s blockchain. This is referred to as a “Bitcoin halving,” and the next one is anticipated to take place in 2024. At that time, the reward will be reduced to 3.125 BTC, which is equivalent to nearly $53,000 at the current exchange rate.

The block rewards will halt when there are 21 million Bitcoins in circulation, and miners will only be paid through transaction fees after that point.

What is electricity costs?

It’s likely that your mining expenses will be greater than your earnings unless you have access to a cheap supply of electricity.

Is Bitcoin mining legal?

Although China is one notable example, other nations have outlawed Bitcoin mining, which is normally permitted in the UAE, USA etc.

What other cryptocurrencies can you mine?

The majority of cryptocurrencies with “proof-of-work” technology can theoretically be mined. Litecoin and Dogecoin are a couple of Bitcoin alternatives, or cryptocurrencies. Some cryptocurrencies, such as Monero, can be mined on a home computer. ASICs are needed by some, while GPUs are used by others. “Graphics processing units” were first created for gaming and other demanding applications.

There are numerous cryptocurrencies, nevertheless, that do not support mining. Many of these use “proof-of-stake” cryptocurrency technology, which relies on staking, a less energy-intensive procedure. To submit a new block and get paid, this means risking some cryptocurrency.

It is noteworthy that Ethereum, the second-most valuable cryptocurrency, just finished the transition to proof of stake.
