To understand how to calculate the electrical energy used to power the bitcoin network, you'll need to understand how bitcoin creation works. These individual sums are called hashes, and there are vast numbers of them—so many, in fact, that you have to think of them in terms of millions of hashes known as megahashes or billions of hashes gigahashes to make any sense of them.

In early , the computers on the bitcoin network were close to exahashes per second. One terahash is a trillion hashes per second, one petahash is a quadrillion hashes per second, and one exahash is one quintillion hashes per second a one followed by 18 zeros. 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. 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.

A block has four fields, or primary attributes:. 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.

How to Mine Bitcoin: The Complete Guide to Bitcoin Mining

Bitcoin mining is the process of verifying bitcoin transactions and recording them in the public blockchain ledger. In blockchain, the transactions are verified by bitcoin users, so basically the transactions have to be verified by the participants of the network. Those who have the required hardware and computing power are called miners. We will talk more about them later, but the important concept to understand here is that there is nothing like a centralized body—a regulatory body, a governing body, a bank—to make bitcoin transactions go through.

Any user with mining hardware and Internet access can be a participant and contribute to the mining community. The process is solved based on a difficult mathematical puzzle called proof of work.

The proof of work is needed to validate the transaction and for the miner to earn a reward. All the miners are completing amongst themselves to mine a particular transaction; the miner who first solves the puzzle gets the reward. Miners are the network participants who have the necessary hardware and computing power to validate the transactions. To understand bitcoin mining, you have to first understand the three major concepts of blockchain.

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. Since then, a whole sector has developed around cryptocurrency and the process of Bitcoin mining.

How to Mine Bitcoin: The Complete Guide

That year, investors worldwide started to buy up the cryptocurrency, and institutional investors followed suit. Since then, a whole network and infrastructure has started to build around Bitcoin and other cryptocurrencies.

    • As the infrastructure required to support the cryptocurrency has grown and developed, so has the value of Bitcoin as more and more investors and institutions have bought into the idea of the decentralized currency. However, while investors worldwide are trading and buying products in Bitcoin, few genuinely understand the infrastructure that supports the cryptocurrency and the Bitcoin mining process. The first real mention and concept of a so-called cryptocurrency was published in It took a decade for this idea to gain traction and become a workable idea.

    The first Bitcoin specification was published in on a cryptography mailing list by Satoshi Nakamoto. This author left the project in without revealing much about himself.

    How Does Bitcoin Mining Work?

    To this day, speculation remains as to the true identity of this individual. One individual cannot influence or develop it alone. Bitcoin can only work correctly with a complete consensus among all users, which means all of its users have a strong incentive to protect the consensus and ensure its longevity.

    For most users, Bitcoin is nothing more than a mobile app or computer program. However, behind the scenes, the technology that supports the asset is incredibly powerful. The core of this technology is the Bitcoin mining network. Digital signatures corresponding to addresses confirm the authenticity of each transaction.

    That means users have full control over sending Bitcoins from their own addresses. The blockchain network gives cryptocurrency payments several advantages over traditional payments. Bitcoin transactions are secure, irreversible, and do not contain sensitive personal information. Transactions are also reversible. By cryptographically encrypting the data, it can be trusted entirely.
