This ledger of past transactions is called the block chain as it is a chain of blocks. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady.
Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to set the history of transactions in a way that is computationally impractical to modify by any one entity.
By downloading and verifying the blockchain, bitcoin nodes are able to reach consensus about the ordering of events in bitcoin. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new units available to anybody who wishes to take part. An important difference is that the supply does not depend on the amount of mining.
In general changing total miner hashpower does not change how many bitcoins are created over the long term. Mining a block is difficult because the SHA hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.
This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information. The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be.
The rate is recalculated every 2, blocks to a value such that the previous 2, blocks would have been generated in exactly one fortnight two weeks had everyone been mining at this difficulty. This is expected yield, on average, one block every ten minutes. As more miners join, the rate of block creation increases.
As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by the other participants in the network. When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network.
Currently this bounty is 6. See Controlled Currency Supply. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.
Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page. The first miner to complete the Proof of Work broadcasts her proposed new block to the wider network of nodes who then check to ensure that the block follows the rules of the protocol.
The key rules here are 1 all transactions in the block are valid ie. If it does, nodes send it on to other nodes who complete the same process. In this way, the new block propagates across the network until it is widely accepted as the 'truth. However, it can and regularly does happen that more than one miner completes the Proof of Work at almost the same time and simultaneously broadcasts his new block out to the network.
Moreover, due to network delays and geographic separation, nodes may receive new proposed blocks at slightly different times. Note that one miner's newly proposed block could be slightly different from another's. This is because, as mentioned, miners are the ones who choose which transactions to include in a block - and even though they tend to optimize for profitability, location and other factors introduce variation. When two miners send out different new blocks, competing versions of the 'truth' begin to propagate across the network.
The network ultimately converges on the 'correct' version of the truth by selecting the chain that grows longer at faster rate. Let's break down that last part. Imagine there are two competing chains. Statistically, one of the miners working on version A is likely to complete the Proof of Work first, broadcasting the new version out to the network. Since nodes always select for the longest chain, version A will quickly come to dominate the network.
In fact, the probability that version B will grow faster vanishes exponentially with each additional block such that by the time six blocks have been added, it's a statistical impossibility. For this reason, a transaction that has been confirmed in six blocks is, for most participants, considered to be set in stone. Note that a block which doesn't end up becoming part of the longest chain version B in our example above is known as an orphan block. It is estimated that such blocks are created between 1 and 3 times per day.
Transactions that are included in an orphan block are not lost. That's because if they weren't already included in the version that ends up being the longest chain, they'll end up being added to the next block of the longest chain. Bitcoin miners are awarded BTC when they find a random number that can only be generated by running the hashing algorithm over and over again.
This process is analogous to a lottery where buying more tickets increases your chances of winning. By dedicating more computing power to the hashing algorithm, miners are effectively buying more lottery tickets. The difficulty level for the Proof of Work algorithm is automatically adjusted every 2, blocks, or roughly every 2 weeks.
Adjustments are made with the goal of keeping the mining of new blocks constant at 10 minutes per block. The difficulty adjustment factors in the total volume of computing power, or 'hashpower,' being applied to the hashing algorithm. As computing power is added, the difficulty is increased, making mining more difficult for everyone.
If computing power is removed, difficulty is reduced, making mining easier. Note that the difficult adjustment system makes bitcoin mining quite different from the mining of precious metals. If, for example, the price of gold rises, more miners are enticed to join the market. The addition of more gold miners will inevitably result in more gold produced.
By forces of supply and demand, this will eventually lower the market price of gold. In Bitcoin's case, however, the volume of bitcoin produced minted is predetermined by the Bitcoin protocol ie. Bitcoin mining is legal in most regions, including the US and Europe. In China the legal status of bitcoin mining is currently in a gray zone. Bitcoin mining is a highly competitive industry with narrow profit margins.
The primary input is electricity, although significant upfront investments in hardware and facilities for housing the hardware are also required. The key hardware involved is known as the Application Specific Integrated Circuit ASIC , which is a computing device specialized for running the Bitcoin hashing algorithm exclusively. Profitably relies mainly on consistent access to low-cost electricity applied to the most efficient ASIC hardware. Bitcoin mining is a naturally equilibrating system.
As the price of bitcoin rises, miner margins expand. This entices more miners to join the market. However, new entrants cause the difficulty of minting new blocks to increase. This requires all participants to expend more resources, thereby reducing profitability across the board. Sustained downturns in the price of bitcoin have historically resulted in a portion of miners quitting due to costs exceeding revenue. In most cases, miners sell their earned bitcoins to cover the costs associated with mining.
These costs, then, contribute to the net sell pressure. Miner's attempts to maximize profitability by holding or selling Bitcoin based on market momentum may have an impact on Bitcoin's price volatility. Here, the argument is that when the price of Bitcoin is rising, miners may attempt to hold longer in the hopes that they can extract more profit. This would result in less net sell pressure, leading to a faster rise in the price. When the price of Bitcoin is falling, however, miners are likely to sell not only their reserves, but also newly acquired bitcoin.
This, in turn, would contribute to volatility on the downside. Choose from Bitcoin, Bitcoin Cash, Ethereum, and more. More Get Started articles. Learn the basics. How do I create a Bitcoin wallet? Bitcoin glossary.
