WHITE BOOK OF THE BITCOIN
WHAT ARE CRYPTOCURRENCIES AND WHAT POSSIBILITIES DID OFFER US?
Bitcoin the father of cryptocurrencies.
Bitcoin and the criptocurrencies are a form of electronic money purely peer-to-peer.
¿How are the may or earned?
First, they are generated with machines built for this purpose, wich solve some cryptographic calculations problems. Finally, as a reward for effort and power consumption, uthe system grants the value that has been generated in bitcoins.
The information of the transactions is not stored in a specific site, but it is distributed and copied in the thousands of nodes existing in the network.
In contrast to digital signatures, the block chain does not need third parties for security and trust in transactions.
However, the main benefits disappear if a trusted third party is still essential in the transactions.
