Bitcoin mining is carried out by specialised computers. Miners achieve this by solving a computational problem that allows them to string together blocks of transactions (hence Bitcoin's famous "block chain"). For this service, miners are rewarded with newly created Bitcoins and transaction fees. All mining starts with the blockchain.
This is a decentralised online ledger that records transactions across the network. A group of approved transactions is called a "block". These blocks are linked together to create a chain, hence the term blockchain. Bitcoin mining is the process by which bitcoin transactions are digitally validated on the bitcoin network and added to the blockchain ledger.
It is done by solving complex cryptographic puzzles to verify blocks of transactions that are updated in the decentralised blockchain ledger. Solving these puzzles requires a lot of computing power and sophisticated equipment. In return, miners are rewarded with bitcoins, which are then put into circulation, hence the name bitcoin mining. Most people think of cryptocurrency mining simply as a way to create new coins.
However, crypto mining also involves validating cryptocurrency transactions on a blockchain network and incorporating them into a distributed ledger. Most importantly, cryptocurrency mining avoids double spending of digital currency in a distributed network. Bitcoin mining is the process of creating new bitcoins by solving extremely complicated mathematical problems that verify bitcoin transactions. When a bitcoin is successfully mined, the miner receives a predetermined amount of bitcoins.
The miner who manages to solve the problem adds a block to the Bitcoin blockchain and receives a reward of 6.25 bitcoins. This miner receives a reward of 6.25 bitcoins (the reward per block is halved approximately every four years). Of course, the tokens miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Of these three options, Bitcoin mining is perhaps the most exciting, as it takes miners on a path of discovery.
When miners mine Bitcoin, they compete with each other to create a 64-digit hexadecimal hash or number that goes into the blockchain ledger as confirmation of that Bitcoin transaction. By downloading and verifying the blockchain, Bitcoin nodes are able to reach a consensus on the order of events in Bitcoin. Apart from the coins minted through the genesis block (the first block, which was created by founder Satoshi Nakamoto), each of those bitcoins came into existence thanks to miners. By creating blocks, bitcoins are obtained as a reward, which increases the number of bitcoins in circulation.
In short, miners have to subtract the time, effort and considerable energy involved in mining Bitcoin to determine their actual earnings. Miners will continue to verify transactions and get paid for it in order to maintain the integrity of the Bitcoin network. If a miner is able to successfully add a block to the blockchain, they will receive 6.25 bitcoins as a reward. The halving exists to slow the rate of Bitcoin inflation and the rate at which new bitcoins are put into circulation, keeping the price of Bitcoin stable.
When multiple simultaneous responses are submitted that are equal to or less than the target number, the Bitcoin network will decide by a simple majority of 51 which miner to honour. If a bitcoin is subsequently sold at a higher price, the miner will have to pay capital gains tax on the difference.
