Bitcoin is commonly abbreviated as "BTC. The bitcoin system is a collection of computers also referred to as "nodes" or "miners" that all run bitcoin's code and store its blockchain. Metaphorically, a blockchain can be thought of as a collection of blocks. In each block is a collection of transactions. Because all the computers running the blockchain has the same list of blocks and transactions, and can transparently see these new blocks being filled with new bitcoin transactions, no one can cheat the system.

Anyone, whether they run a bitcoin "node" or not, can see these transactions occurring live. Bitcoin has around 12, nodes, as of January , and this number is growing, making such an attack quite unlikely.

But in the event that an attack was to happen, the bitcoin miners—the people who take part in the bitcoin network with their computer—would likely fork to a new blockchain making the effort the bad actor put forth to achieve the attack a waste. Balances of bitcoin tokens are kept using public and private "keys," which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key comparable to a bank account number serves as the address which is published to the world and to which others may send bitcoins.

The private key comparable to an ATM PIN is meant to be a guarded secret and only used to authorize bitcoin transmissions. Bitcoin keys should not be confused with a bitcoin wallet, which is a physical or digital device that facilitates the trading of bitcoin and allows users to track ownership of coins. The term "wallet" is a bit misleading, as bitcoin's decentralized nature means that it is never stored "in" a wallet, but rather decentrally on a blockchain.

Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments.

The independent individuals and companies who own the governing computing power and participate in the bitcoin network—bitcoin "miners"—are in charge of processing the transactions on the blockchain and are motivated by rewards the release of new bitcoin and transaction fees paid in bitcoin. These miners can be thought of as the decentralized authority enforcing the credibility of the bitcoin network. New bitcoin is released to the miners at a fixed, but periodically declining rate. There are only 21 million bitcoin that can be mined in total.

As of January 30, , there are approximately 18,, bitcoin in existence and 2,, bitcoin left to be mined. In this way, bitcoin other cryptocurrencies operate differently from fiat currency; in centralized banking systems, currency is released at a rate matching the growth in goods; this system is intended to maintain price stability. A decentralized system, like bitcoin, sets the release rate ahead of time and according to an algorithm.

Bitcoin mining is the process by which bitcoins are released into circulation. Generally, mining requires the solving of computationally difficult puzzles in order to discover a new block , which is added to the blockchain. Bitcoin mining adds and verifies transaction records across the network.

For adding blocks to the blockchain, miners are rewarded with a few bitcoins; the reward is halved every , blocks. The block reward was 50 new bitcoins in On May 11th, , the third halving occurred, bringing the reward for each block discovery down to 6. A variety of hardware can be used to mine bitcoin. However, some yield higher rewards than others. These elaborate mining processors are known as "mining rigs.

One bitcoin is divisible to eight decimal places millionths of one bitcoin , and this smallest unit is referred to as a Satoshi. The domain name bitcoin. Today, at least, this domain is "WhoisGuard Protected," meaning the identity of the person who registered it is not public information.

A person or group using the name Satoshi Nakamoto makes an announcement on the Cryptography Mailing list at metzdowd. This now-famous whitepaper published on bitcoin. The first Bitcoin block is mined, Block 0. The first version of the bitcoin software is announced on the Cryptography Mailing list. Block 1 is mined, and bitcoin mining commences in earnest.

No one knows who invented bitcoin, or at least not conclusively. Satoshi Nakamoto is the name associated with the person or group of people who released the original bitcoin white paper in and worked on the original bitcoin software that was released in In the years since that time, many individuals have either claimed to be or have been suggested as the real-life people behind the pseudonym, but as of January , the true identity or identities behind Satoshi remains obscured. Although it is tempting to believe the media's spin that Satoshi Nakamoto is a solitary, quixotic genius who created Bitcoin out of thin air, such innovations do not typically happen in a vacuum.

All major scientific discoveries, no matter how original-seeming, were built on previously existing research. The bitcoin whitepaper itself cites Hashcash and b-money, as well as various other works spanning several research fields. Perhaps unsurprisingly, many of the individuals behind the other projects named above have been speculated to have also had a part in creating bitcoin.

There are a few possible motivations for bitcoin's inventor deciding to keep their identity secret. One is privacy: As bitcoin has gained in popularity—becoming something of a worldwide phenomenon—Satoshi Nakamoto would likely garner a lot of attention from the media and from governments.

Another reason could be the potential for bitcoin to cause a major disruption in the current banking and monetary systems. If bitcoin were to gain mass adoption, the system could surpass nations' sovereign fiat currencies. This threat to existing currency could motivate governments to want to take legal action against bitcoin's creator.

The other reason is safety. Looking at alone, 32, blocks were mined; at the reward rate of 50 bitcoin per block, the total payout in was 1,, bitcoin. One may conclude that only Satoshi and perhaps a few other people were mining through and that they possess a majority of that stash of bitcoin. Someone in possession of that much bitcoin could become a target of criminals, especially since bitcoins are less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and literally kept under a mattress.

While it's likely the inventor of bitcoin would take precautions to make any extortion-induced transfers traceable, remaining anonymous is a good way for Satoshi to limit exposure. Bitcoins can be accepted as a means of payment for products sold or services provided.

An online business can easily accept bitcoins by adding this payment option to its other online payment options: credit cards, PayPal, etc. Those who are self-employed can get paid for a job related to bitcoin.
