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.

Bitcoin mining is the process by which Bitcoin transactions are validated digitally on the Bitcoin network and added to the blockchain ledger. It is done by solving complex cryptographic hash puzzles to verify blocks of transactions that are updated on the decentralized blockchain ledger. Solving these puzzles requires powerful computing power and sophisticated equipment.
In return, miners are rewarded with Bitcoin, which is then released into circulation hence the name Bitcoin mining. 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. It is a physical currency in the form of notes and coins. However, we can use it in both physical and digital forms. 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. Value is backed by the trust of its users. The more users are willing to transact with Bitcoin, the more stable it becomes.
Bitcoin transactions are validated using blockchain technology and so do not require an intermediary for validation. The concepts of decentralization, cryptography, and consensus guarantee a secure network and security of bitcoin transactions.
Blockchain is a decentralized peer-to-peer network that has been hailed as highly secure and transparent, hence trustworthy. 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. 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.
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.
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 root, the identifier of a Merkle tree, is stored in the block header. The block header contains information about the block and includes the following components:. 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.
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.
Other than that, people who are curious about this technology and how it works enjoy experimenting with this relatively new technology. The halving event happens after every , blocks have been mined, which is roughly after every four years. The number of Bitcoins in circulation is calculated by the halving theory laid out by Satoshi Nakamoto in the Bitcoin protocol. When Bitcoin was first launched, the reward for every block mined started at 50 Bitcoins. To date, three halving events have taken place, and the block reward went from 50 from , 25 from , The last Bitcoin halving event took place on May 11th, By September , The next Bitcoin halving event is expected to take place in the early months of the year Halving should continue until all blocks are mined, and the 21 million Bitcoin supply cap is attained sometime in After this, the Bitcoin miners will only earn from transaction fees.
Mining must have been a lot easier in the early days of its launch. As bitcoin and the blockchain concept were relatively new, mining was left to hobbyists on a discovery path. As bitcoin continues to gain wider adoption, it has also succeeded in drawing keen interest from investors, miners, and companies harnessing cryptocurrency as a mode of payment for products and services. With this, mining has become a very competitive undertaking, and the hardware and software demands for bitcoin mining are also more sophisticated.
Figure 50 BTC block rewards every 10 minutes in the space of less competition, lower capital requirements, and lower running power and device maintenance costs. Well, that was then when fewer miners enjoyed the monopoly. However, competition is stiffer, and mining difficulty is greater.
