Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen.

Bitcoin is the first implementation of a concept called «cryptocurrency», which was first described in by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority.

This smallest fraction of a Bitcoin — the penny of the Bitcoin world — is referred to as a Satoshi, after the anonymous creator of Bitcoin. This all gets confusing, because Bitcoin is also the name of the payment network on which the Bitcoin digital tokens are stored and moved.

Unlike traditional payment networks like Visa, the Bitcoin network is not run by a single company or person. The system is run by a decentralized network of computers around adn world that keep track of all Bitcoin transactions, similar to the way Wikipedia is maintained by a decentralized network of writers and editors. The record of all Bitcoin transactions that these computers are constantly updating is known as the blockchain.

Criminals have taken to Bitcoin because anyone can open a Bitcoin address and start sending and receiving Bitcoins without giving a name or identity. There is no central hoa that could collect this information. Bitcoin first took off in after drug dealers began taking payments in Bitcoin on the black-market website known as the Silk Road. Although the Silk Road was shut down insimilar sites have popped up to replace usedd. More recently, Bitcoin has become a method for making ransom payments — for example, when your computer is taken over by so-called ransomware.

The records of the Bitcoin network, including all balances and transactions, are stored on every computer helping to maintain the network — about 9, computers in late If the government made it illegal for Americans to participate in this bitcions, the computers and people keeping the records in other countries would still be able to continue.

The decentralized nature of Bitcoin is also one of the qualities that have yow it popular with people who are suspicious of government authorities. Anyone helping to maintain the database of all Bitcoin botcoins — the blockchain — could change his or her own copy of the records to add more money.

But if someone did that, the other computers maintaining the records would see the aee, and the changes would be bitccoins. Only a small percentage of all ho on the Bitcoin network are explicitly illegal. Most transactions are people buying and selling Bitcoins on exchanges, speculating on future prices.

Bitcoin mining refers to the process through which new Bitcoins are created and given to computers helping to maintain the network. The what are bitcoins and how are they used involved in Bitcoin mining are in a sort of computational race to process new transactions coming onto the network.

The winner — generally the person with the fastest computers — gets a chunk of new Bitcoins, The reward is halved biitcoins four years. There is generally a new winner about every 10 minutes, and there will be until there are 21 million Bitcoins in the world. At that point, no new Bitcoins will be created. This cap is expected to nitcoins reached in So far, about 16 million Bitcoin have been distributed.

Every Bitcoin in existence was created through this method and initially given to a computer helping to maintain the records. Anyone can set his or her computer to mine Bitcoin, but these days only people with specialized hardware manage to win the race.

While several people have been identified bitcoibs likely candidates to be Satoshi, as the creator is known in the world of Bitcoin, no one has been confirmed as the real Satoshi, and the search has gone on. Satoshi created the original rules of the Qre network and then released the software to the world in Satoshi largely disappeared from view two years later.
