How many bitcoins do you get for mining a block

In the bitcoin network, as mentioned, users called miners are trying to solve a mathematical puzzle. The puzzle is solved by varying a nonce that produces a hash value lower than a predefined condition, which is called a target. As of today, Bitcoin miners who solve a puzzle get a reward of Once a block is added to the blockchain, the bitcoins associated with the transactions can be spent and the transfer from one account to the other can be made.

To generate the hash, Bitcoin miners use the SHA hashing algorithm and define the hash value. If it is less than the defined condition the target , then the puzzle is deemed to be solved. If not, then they keep modifying the nonce value and repeat the SHA hashing function to generate the hash value again, and they keep doing this process until they get the hash value that is less than the target. To do that, what would the steps be?

First, transaction data is shared with bitcoin users from the memory pool. The transaction sits in an unmined pool of memory transactions. In a memory pool, unconfirmed transactions wait until they are verified and included in a new block. Bitcoin miners compete to validate the transaction using proof of work. The miner who solves the puzzle first shares the result across the other nodes.

Once the block has been verified, the nonce has been generated, then the nodes will start granting their approval. If maximum nodes grant their approval, the block becomes valid and is added to the blockchain. The miner who has solved the puzzle will also receive a reward of The 10 bitcoins for which the transaction was initiated now will be transferred from Beyonce to Jennifer. In proof of work, a predefined condition the target is adjusted for every 2, blocks, which is approximately every 14 days. The average time to mine a block is 10 minutes, and to keep the time frame for block generation within 10 minutes, the target keeps adjusting itself.

The difficulty of the puzzle changes depending on the time it takes to mine a block. This is how the difficulty of a block is generated: It is the hash target of the first block divided by the hash target of the current block. This is the difficulty being changed after every 2, blocks, so basically it is very hard to generate the proof of work—but it is very easy for the miners to verify once someone have solved the puzzle.

And once the majority of the miners reach a consensus, the block gets validated and added to the blockchain. 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. In the early days of bitcoin, miners used to solve the mathematical puzzles using regular processors—controlling processor units CPUs.

It used to take a lot of time for mining Bitcoins and other cryptocurrencies, even though the difficulty levels were easier than today. As mentioned above, the difficulty level keeps changing and growing, so the miners also had to increase their processing power. They discovered that graphical processing units GPUs proved to be more efficient than regular CPUs, but this also had the drawback of consuming more electricity.

A miner has to calculate the return on investment based on the hardware and the cost of electricity and other resources needed to do the mining. Today miners use hardware called ASIC application-specific integrated circuit , which was specifically introduced for mining Bitcoin and other cryptocurrencies. It consumes less power and has a higher computing power.

Miners are profitable when their cost of resources to mine one block is less than the price of the reward.

So, Bitcoin miners use their resources hardware and electricity to verify a transaction, and each time a block is mined, new bitcoins are created in the network. The total supply is limited to 21 million bitcoins; 17 to 18 million bitcoins have already been mined, so only 3 to 4 million are left. As of today, a reward of If individuals buy multiple lottery tickets and pool their tickets together, then this will increase their chances of winning.

If someone wins the lottery, then based on the contribution, the reward is distributed among all the participants. The bitcoin mining pool is similar: Multiple nodes share their resources to mine a block. When a block is solved, the miners split the reward based on the amount of processing power they have invested.

The pool members generate a final hash value, then the bitcoin reward gets distributed proportionally among the participants based on the resources they contributed. You can also see an example of a mining pool, in which the participants are sharing their mining resources, and you can see both the unconfirmed reward for which they are mining and what they have earned so far.

There are lots of different bitcoin mining computers out there, but many companies have focused on Application-Specific Integrated Circuit ASIC mining computers, which use less energy to conduct their calculations.

Mining companies that run lots of ASIC miners as businesses claim to use only one watt of power for every gigahash per second of computing performed when mining for bitcoins. If this information is correct, the bitcoin network in consumes gigawatts GW per second.

What Happens to Bitcoin After All 21 Million Are Mined?

This converts to about 63 terawatt-hours TWh per year. This staggering amount of power is the equivalent of million horses 1. Regardless of the number of miners, it still takes 10 minutes to mine one Bitcoin. At seconds 10 minutes , all else being equal it will take 72, GW or 72 Terawatts of power to mine a Bitcoin using the average power usage provided by ASIC miners.

One watt per gigahash per second is fairly efficient, so it's likely that this is a conservative estimate since a large number of residential miners use more power.

Media outlets and bloggers have produced various estimates of the electrical energy used in bitcoin mining, so the accuracy of reported power use is sketchy, at best. To perform a cost calculation to understand how much power it would take you to create a bitcoin, you'd first need to know electricity costs where you live and the amount of power you would consume.

More efficient mining equipment means less power consumption, and less power consumption means lower power bills. The lower the price of electricity, the less cost there is to miners—thus increasing the value of the Bitcoin to miners in lower-cost areas after accounting for all the costs associated with setup. Bitcoin's exchange rate has fluctuated wildly throughout its history—but as long as it's price stays above the cost to produce a coin, doing the work in an area where energy costs are very low is important to make the practice worthwhile.

How Much Power Does It Take to Create a Bitcoin?

The price placed on bitcoin in terms of energy consumption, and thus environmental impact, depends on how useful it's going to be to society. This then begs the question—if bitcoin continues to rise in popularity and price, how much more power will be consumed, and will it ultimately be worth the environmental cost?
