Bitcoin mining explained
Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a "mining rig" is a colloquial metaphor. Bitcoin mining is the process of discovering new blocks, verifying transactions and adding them to the Bitcoin blockchain. Most people think of crypto mining simply as a way of creating new coins.

Most people think of crypto mining simply as a way of creating new coins. Crypto mining, however, also involves validating cryptocurrency transactions on a blockchain network and adding them to a distributed ledger.
Most importantly, crypto mining prevents the double-spending of digital currency on a distributed network. Like physical currencies, when one member spends cryptocurrency, the digital ledger must be updated by debiting one account and crediting the other. However, the challenge of a digital currency is that digital platforms are easily manipulated. This gives miners the extra responsibility of securing the network from double-spending. Meanwhile, new coins are generated to reward miners for their work in securing the network.
Since distributed ledgers lack a centralized authority, the mining process is crucial for validating transactions. Miners are, therefore, incentivized to secure the network by participating in the transaction validation process that increases their chances of winning newly minted coins. In order to ensure that only verified crypto miners can mine and validate transactions, a proof-of-work PoW consensus protocol has been put into place. PoW also secures the network from any external attacks.
Proof-of-Work Crypto mining is somewhat similar to mining precious metals. While miners of precious metals will unearth gold, silver, or diamonds, crypto miners will trigger the release of new coins into circulation. For miners to be rewarded with new coins, they need to deploy machines that solve complex mathematical equations in the form of cryptographic hashes.
A hash is a truncated digital signature of a chunk of data. Hashes are generated to secure data transferred on a public network. Miners compete with their peers to zero in on a hash value generated by a crypto coin transaction, and the first miner to crack the code gets to add the block to the ledger and receive the reward.
Each block uses a hash function to refer to the previous block, forming an unbroken chain of blocks that leads back to the first block. For this reason, peers on the network can easily verify whether certain blocks are valid and whether the miners who validated each block properly solved the hash to receive the reward. Over time, as miners deploy more advanced machines to solve PoW, the difficulty of equations on the network increases.
At the same time, competition among miners rises, increasing the scarcity of cryptocurrency as a result. How to Start Mining Cryptocurrencies Mining cryptocurrencies requires computers with special software specifically designed to solve complicated, cryptographic mathematic equations.
Over the years, however, CPU chips have become impractical for mining most cryptocurrencies due to the increasing difficulty levels. In addition, the GPUs in the mining rig must be connected to a reliable internet connection at all times.
Each crypto miner is also required to be a member of an online crypto mining pool as well. Different Methods of Mining Cryptocurrencies Different methods of mining cryptocurrencies require different amounts of time. However, many find CPU mining to be too slow and impractical today because it takes months to accrue even a small amount of profit, given the high electrical and cooling costs and increased difficulty across the board.
GPU mining is another method of mining cryptocurrencies. It maximizes computational power by bringing together a set of GPUs under one mining rig. For GPU mining, a motherboard and cooling system is required for the rig. Similarly, ASIC mining is yet another method of mining cryptocurrencies. However, they are expensive, meaning that, as mining difficulty increases, they quickly become obsolete.
Cloud mining allows individual miners to leverage the power of major corporations and dedicated crypto-mining facilities. Bitcoin Advantages Compared to traditional fiat currencies, assets can be transferred faster on the bitcoin network. Plus, all the information is available on a public ledger, so anyone can view the transactions. What Is Blockchain? As mentioned, blockchain is the underlying technology of bitcoin.
Blockchain is a public distributed ledger in which transactions are recorded in chronological order. Any record or transaction added to the blockchain cannot be modified or altered, meaning transactions are safe from hacking. A block is the smallest unit of a blockchain, and it is a container that holds all the transaction details. A block has four fields, or primary attributes: Previous hash: This attribute stores the value of the hash of the previous block, and that's how the blocks are linked to one another.
Data: This is the aggregated set of transactions included in this block—the set of transactions that were mined and validated and included in the block. Every block is supposed to generate a hash value, and the nonce is the parameter that is used to generate that hash value. The proof of work is the process of transaction verification done in blockchain. Hash: This is the value obtained by passing the previous hash value, the data and the nonce through the SHA algorithm ; it is the digital signature of the block.
SHA is a cryptographic hash algorithm that produces a unique bit alphanumeric hash value for any given input, and that is the unique feature of this cryptographic algorithm: Whatever input you give, it will always produce a bit hash. Public distributed ledger: A distributed ledger is a record of all transactions maintained in the blockchain network across the globe. In the network, the validation of transactions is done by bitcoin users.
SHA Blockchain prevents unauthorized access by using a hash function called SHA to ensure that the blocks are kept secure. They are digitally signed. Their hash value, once generated, cannot be altered. SHA takes an input string of any size and returns a fixed bit output, and it is a one-way function—you cannot derive the reverse of the input reverse fully from the output what you have generated.
Proof of work: In blockchain mining, miners validate transactions by solving a difficult mathematical puzzle called proof of work. To do that, the primary objective of the miner is to determine the nonce value, and that nonce value is the mathematical puzzle that miners are required to solve to generate a hash that is less than the target defined by the network for a particular block. Bitcoin Profit and Bitcoin Mining Profitability Bitcoin Profit is an automated crypto robot that helps trade Bitcoins and other cryptocurrencies to earn profit.
It uses an AI algorithm to identify trading opportunities in the crypto market that can automatically close and open your trade, saving your time and manual intervention during trading. However, technical knowledge is required to calculate the profit generated through the Bitcoin mining process. Talking about the actual Bitcoin profit - the real money making - it depends upon the cost of the AISC hardware, electricity consumption, and the effectiveness of the mining software.
Bitcoin Mining profitability has decreased in recent times compared to the previous years because of the rise in electricity costs, costlier hardware, difficulty in mining due to an increase in competition, and a decrease in the Bitcoin prices. Bitcoin vs. Traditional Currencies While both Bitcoin and traditional currency are similar in that both are a store of value, they differ in many ways.
First things first, Bitcoin is the first and most recognized cryptocurrency - a digital currency that is secured by cryptography. Traditional currency, also referred to as fiat money, is a government-issued and regulated currency. Some differences between Bitcoin and traditional currencies are illustrated in the table below. Bitcoin Tangibility It is a virtual currency and can only be used in its digital form It is a physical currency in the form of notes and coins.
However, we can use it in both physical and digital forms Regulation Issued through mining and controlled by a decentralized distributed network of computers Issued and controlled by central government authorities, i. Owing to this, the traditional currency is the legal tender in the country governed by the issuing authority.
Governance Governed by a consensus mechanism in which the majority rules Purely governed by the central bank Value Value is backed by the trust of its users. The more users are willing to transact with Bitcoin, the more stable it becomes. This is because records in the blockchain network are secured using timestamps and cryptographic hash functions in such a way that after being added to the ledger, it is almost impossible and impractical to alter the transactions. At the core of blockchain security is the absence of centralized control.
Here is a breakdown of what happens during bitcoin mining The Mining Requirements A bitcoin miner will first select their tools of the trade and set them up. These include: Hardware GPU graphics processing unit , SSD for crypto mining, or ASIC application-specific integrated circuit Mining software A wallet Preferred mining pool if one chooses pool mining option instead of solo mining Once all these are set up and the system fired up, it performs the mining process autonomously.
Any other human involvement comes in the event of system or network failure, power outage, or regular system maintenance. Elements of a Bitcoin Transaction When a transaction is initiated in the bitcoin network, three elements are involved: A transaction input A transaction output The transaction amount For every transaction input, a bitcoin mining software generates a unique cryptographic hash puzzle that is difficult to decode.
The software then groups the number of transactions required to form a block into a Merkle tree. The Merkle Tree and the SHA Algorithm A Merkle tree is a data structure of the hashes in a block and acts as a summary of all the transactions in the block. In the Merkle tree, hashes of individual transactions known as transaction IDs are paired repeatedly using the SHA algorithm until only one hash identifies the entire tree.
This hash is known as the Merkle root or root hash. The Merkle tree enables the efficient verification of transactions in the bitcoin network. The block header contains information about the block and includes the following components: The version number of the bitcoin software The hash of the previous block The Merkle root root hash Timestamp Cryptographic nonce The target This is the information miners will use to solve the hash puzzle and add a block transaction.
Solving the Hash Puzzle Miners must solve the hash puzzle by finding the hash below a given target through the difficulty requirement. The target, stored in the header, is expressed as a digit number that will determine the mining difficulty based on the number of miners competing to solve a hash function.
It is important to note that this difficulty adjusts after every blocks are created depending on how much time it took miners in the previous blocks to solve an equation. This also helps to maintain the rate at which transactions are appended in the blockchain at 10 minutes. To solve the hash puzzle, miners will try to calculate the hash of a block by adding a nonce to the block header repeatedly until the hash value yielded is less than the target.
Once a mining computer solves the puzzle, a new block is successfully created that is validated in the Bitcoin network after a consensus between the nodes has been reached. When a block is validated, the transactions bundled in it are verified and the block is added to the chain. As indicated above, this happens every 10 minutes. As there will be many miners systems competing to solve the puzzle, the first miner to get the correct hash value earns a reward in Bitcoin.
This process allows more Bitcoins in circulation. However, experts have seen it as a huge advantage because the scarcity of supply breeds value and a stable price for the oldest crypto. From the genesis Bitcoin block mined in with 50 bitcoins, more bitcoins have since been mined and released into circulation. Bitcoin mining ensures that blocks of transactions are created and stacked in the right order in a way that can be traced and proven mathematically.
With the creation of blocks comes bitcoins as a reward, which increases the number of bitcoins in circulation. Bitcoin architecture was structured ingeniously such that every 10 minutes, a block is discovered, and a fixed bitcoin award is offered for every block that is mined.
Prevention of Hacking What if someone tries to hack the data? Each block has solved a puzzle and generated a hash value of its own, which is its identifier. Now suppose a person tries to tamper with block B and change the data. The data is aggregated in the block, so if the data of the block changes, then the hash value that is the digital signature of the block will also change.
It will therefore corrupt the chain after it—the blocks ahead of block B will all get delinked, because the previous hash value of block C will not remain valid. For a hacker to make the entire blockchain valid for the block B that has been changed, he or she would have to change the hash value of all the blocks ahead of block B.
This would require a huge amount of computing power and is next to impossible. With this method, blockchain is non-hackable and prevents data modification. Why Mine Bitcoin? Other than that, people who are curious about this technology and how it works enjoy experimenting with this relatively new technology. How to Mine Bitcoin? The Bitcoin miners are suggested to use mining hardware, such as Ebang, Antminer, Minedollars, AvalonMiner, or more that generates new Bitcoins after every 10 minutes.
To mine Bitcoin, the miner is advised to invest in a powerful setup designed specifically for mining cryptos. Excessive or advanced computer knowledge must be possessed to operate the hardware system. The user then has to create at least one Bitcoin wallet for Bitcoin Mining that is secured and convenient.
Once the mining hardware is set up and the Bitcoin wallet is created, the miner must adopt strategies to install and configure the mining software. The miner has to apply technical knowledge to improve the mining capacity. The mining process then begins after the miner downloads a soft copy of the blockchain of Bitcoin and clicks on the start button.
The miner needs to monitor the progress regularly to ensure that the mining application runs smoothly. However, the miner does not need to do anything manually and can rely on the mining hardware after the mining process is started. Because of the Bitcoin Mining process, new blocks are added to the blockchain.
CRYPTO SECURITY UNITED STATES REDDIT
As a result, verification is trustworthy when the network is controlled by honest nodes, but it becomes more susceptible when the network is controlled by an attacker. While the network's nodes can independently validate transactions, the simplified technique may be fooled by attacker-created transactions while maintaining network dominance.
Accepting alerts from network nodes when they discover an incorrect block and requesting the user who leaves the entire block and the alert transactions to validate the discrepancy is one way to protect oneself. Businesses that accept payments on a regular basis will want to run their own nodes for increased security and faster verification. As the miners process these various transactions, they create a block, which is then confirmed and added to the blockchain.
The bitcoin blockchain keeps track of all bitcoin transactions all the way back to the beginning. Incentives for miners Bitcoin is generated by compensating miners for their efforts in solving mathematical and cryptographic difficulties. Every 10 minutes, miners are rewarded for their efforts with fresh bitcoins.
By convention, the first transaction in a block is a special transaction that creates a new currency for the block's creative node. Because there is no central authority issuing money, this gives an incentive for them to support nodes in the network and provides a method of initially dispersing coins in circulation.
Advertisement Gold miners invest resources to add gold to circulation, so the continual addition of a specific number decreasing of new coins is equivalent. The time spent on the computer and the power necessary for your operation are resources in this scenario. Transaction fees might potentially be used to fund the incentive. The transaction rate is added to the incentive value of the block containing the transaction if the transaction's output value is less than its input value.
Once a sufficient number of default coins have been sent, the incentive can be reduced to only the transaction fee, resulting in completely free inflation. This incentive encourages nodes to maintain their integrity. If a greedy attacker accumulates more CPU power than all nodes on the network, it must choose between scamming users by stealing payments and producing new currencies.
By following these principles, attackers should be able to identify a more profitable path. Otherwise, this would simply harm attacker nodes by providing them with more new coins than the total of all other honest nodes, undermining the system and the legitimacy of its own assets. Will the miner get compensated on a regular basis? To earn bitcoins, you must be the first miner to solve a numeric puzzle with the correct answer, or the closest answer which is also known as proof of work PoW.
How does Mining work? As we already said- Bitcoin mining is a process of solving mathematical problems for which you get rewarded in Bitcoin. If you can imagine those problems as puzzles- everyone is trying to solve a puzzle, and whoever solves it first gets 1 Bitcoin. In the beginning, this was easy as not many miners were out there, so the puzzles were simple. Still, not everything is lost for you, my friend. After several years of Bitcoin, many new altcoins joined the crypto revolution.
Since most of those altcoins can still be mined with average hardware, there is now a specialized mining software that mines the most profitable altcoins and then pays you in Bitcoin. And this is what this website is all about- mine the cryptocurrency with the tools we feature on our website and get paid in Bitcoin!
What Is The Purpose of Mining? So, you turn on your PC , install and run Bitcoin mining software and start making money- too good to be true? Well, not necessarily. Remember those cryptography puzzles we mentioned above? Well, cryptography is a cornerstone of IT security, making our programs and protocols more secure, by encrypting all of the sensitive data. And Bitcoin is no exception- it even went one step ahead, making a financial system where people from all over the world are securing the network with the power of their hardware.
