There are currently 12, nodes estimated to be running Bitcoin's code. Though anyone can participate in Bitcoin's network as a node, as long as they have enough storage to download the entire blockchain and its history of transactions, not all of them are miners.

Bitcoin mining is the process by which people use their computers to participate in Bitcoin's blockchain network as a transaction processor and validator. Bitcoin uses a system called proof of work PoW. This means that miners must prove they have put forth effort in processing transactions to be rewarded. This effort includes the time and energy it takes to run the computer hardware and solve complex equations.

Faster computers with certain types of hardware yield larger block rewards and some companies have designed computer chips specifically built for mining. These computers are tasked with processing Bitcoin transactions, and they are rewarded for doing so.

The term mining is not used in a literal sense but as a reference to the way precious metals are gathered. Bitcoin miners solve mathematical problems and confirm the legitimacy of a transaction.

They then add these transactions to a block and create chains of these blocks of transactions, forming the blockchain. When a block is filled up with transactions, the miners that processed and confirmed the transactions within the block are rewarded with bitcoins. Transactions of greater monetary value require more confirmations to ensure security. This process is called mining because the work performed to get new bitcoins out of the code is the digital equivalent to the physical work done to pull gold out of the Earth.

El Salvador made Bitcoin legal tender on June 9, It is the first country to do so. The cryptocurrency can be used for any transaction where the business can accept it. The U. After every , blocks mined, or roughly every four years, the block reward given to Bitcoin miners for processing transactions is cut in half.

This cuts in half the rate at which new bitcoins are released into circulation. This is Bitcoin's way of using a synthetic form of inflation that halves every four years until all bitcoins are released into circulation.

This system will continue until around the year At that point, miners will be rewarded with fees for processing transactions, which network users will pay. These fees ensure that miners still have the incentive to mine and keep the network going.

The idea is that competition for these fees will cause them to remain low after the halvings are finished. The halving is significant because it marks another drop in the rate of new Bitcoins being produced as it approaches its finite supply: the total maximum supply of bitcoins is 21 million. As of October , there are about In , the reward for each block in the chain mined was 50 bitcoins. After the first halving, it was 25, and then To put this in another context, imagine if the amount of gold mined out of the Earth was cut in half every four years.

If gold's value is based on its scarcity, then a "halving" of gold output every four years would theoretically drive its price higher. These halvings reduce the rate at which new coins are created and thus lower the available amount of new supply, even as demand might increase. This can cause some implications for investors as other assets with low or finite supply, like gold, can have high demand and push prices higher.

In the past, these Bitcoin halvings have correlated with massive surges in Bitcoin's price. The first halving, which occurred on Nov. The second Bitcoin halving occurred on July 9, The most recent halving occurred on May 11, Though these two announcements may have temporarily created a price drop in Bitcoin, there is the potential that the price fluctuations are more related to the halving behavior we have observed previously. The theory of the halving and the chain reaction that it sets off works something like this:.

In the event that a halving does not increase demand and price, then miners would have no incentive. The reward for completing transactions would be smaller, and the value of Bitcoin would not be high enough.

To prevent this, Bitcoin has a process to change the difficulty it takes to get mining rewards, or in other words, the difficulty of mining a transaction. In the event that the reward has been halved, and the value of Bitcoin has not increased, the difficulty of mining would be reduced to keep miners incentivized.

Now, this round won't take too long to finish as there is only a small range of possible numbers to guess from. You might be left wondering, Wow! This game is too easy? So, part of the built-in rules of the game to make it more challenging is that after rounds, the difficulty for future rounds increases. This is achieved by increasing the range of numbers the players need to guess from. So, in the th round, the players are now required to guess a number between 0 and 10, These two players keep playing the game, with the winning player earning bitcoins for each round.

The game is still too easy? Then the game will keep increasing the range of numbers available to guess from after every rounds. This difficulty adjustment is made with the goal of making each round take approximately 10 minutes for the players involved to guess a winning number.

As more players enter the game, the time it takes to guess a correct number is reduced since there are more players making guesses. As a result, the game will increase the difficulty of guessing a winning number. The difficulty can be also adjusted downwards when some players decide to quit playing and there is a reduced number of attempted guesses being made.

The game always attempts to satisfy the rule where the average time to guess a winning number for each round is approximately 10 minutes. So, what is the point of playing the game in the first place? The game is important as it a procedure which helps verify and secure the history of transactions in the Bitcoin network.

For anyone to add new transactions to the network, they would need to play and win a round which requires extensive computing power.
