1.8 Bitcoin and Blockchain

Оглавление

In 2009 a new form of digital currency was introduced to the world, a cryptocurrency called Bitcoin. Created anonymously, it works on the basis of peer-to-peer financing. There are no banks, no third parties, no bank vaults, no cash machines involved with Bitcoin.

Bitcoins are stored in a digital wallet which is kept on your computer or stored in the cloud. You buy or sell Bitcoins on Bitcoin exchanges, such as Coinbase and Gemini Exchange. You can buy Bitcoins in any currency and transaction fees are smaller than standard currency exchange rates, which makes them popular for large overseas payments.

Transactions are recorded online in a transparent register which is called a blockchain and all transactions are checked electronically.
