Abstract

    Bitcoin is an advanced type of electronic money that was invented by unknown parties in 2008.It is based in the virtual world and is based on the pillars of cryptography, as it is an encrypted electronic currency that is traded between two electronic devices using (peer-to-peer) technology, that is, ciphers are traded between two parties, one of which knows the other by symbols only.That is , it is not required to disclose the real identities of users, and it has the characteristics that distinguish it from traditional currencies, represented by its great speed, reducing the cost of remittances, and dispensing with the role of the conventional mediator in traditional banking operations.
