Bitcoin
Bitcoin - the first cryptography in history. For the first time, the concept of cryptography was proposed by Way Daim in 1998. In his e-mail newsletter, he proposed the idea of a new form of money, in which a cryptography would be used instead of the central control body to control emissions and transactions. Later, the anonym of Satoshi Nakamoto (there is a thought that under this pseudonym a group of programmers is hiding) proved the viability of this concept in its cryptographic e-mail distribution, and a year later it presented to the public trial Bitcoin.
For a regular user Bitcoin is a mobile application or computer program that gives access to Bitcoin wallet. Using this wallet you can do all the operations associated with cryptographic currencies. In fact, under Bitcoin is understood the public register, in another way it is also called blockade. It contains the history of all transactions that have ever been performed, which can be seen and monitored by any user.
You can get Bitcoin in several ways: landing - a process of cultivating cryptocurrency; exchange is a simple exchange of Bitcoins via some of the users next to you. There is a special service for this; the purchase is also a simple operation for the acquisition of Bitcoins; receiving Bitkoins for the payment of their goods and services.
How does the Bitcoin transaction work? In fact, the transaction is Bitcoin. But, to understand how it works, let's figure out one simple task. Lilly wants to send Bitcoin to her friend Billy. In order to do this, she should know: The address from which the Bitcoins came to the Lilly purse (entrance); The sum is the number of Bitcoins that Lilly wants to send to Billy; Billy’s address (exit).
Now she can forward the necessary number of Bitcoins to Billy. To do an operation, she will also need to know the private key. He, like the address, consists of a random set of numbers and letters. However, unlike an address, the key must be kept secret. When Lilly sends Bitcoin Billy, she signs the application with a key and data consisting of 3 items (entry, amount and exit). Then this request is sent to the recipient. During data transfer, the miners process this application and add it to the global chain of blocks (BlockChain), after which Billy receives Bitcoins in his wallet. In this way, the transaction process takes place.
The first transaction in the world was made on January 12, 2009 and received the name "block of genesis." Its sender was already known to us by Satoshi Nakomo, and the recipient is Hal Finny, the inventor of one of the RPOW algorithms.
The first transaction, when Bitcoins paid for the goods, was made on May 22, 2010. In Florida, the programmer bought two pizzas for 10,000 Bitcoins. Today it is the most expensive pizza in the world - after seven years it costs $ 21.3 million.
