Bitcoin

Bitcoin is characterized by being decentralized, is not backed by any government or central bank and "lacks legal security." It uses a work test system to prevent double spending (that the same bitcoin is used several times) and reach consensus among all the nodes that make up the network exchanging information about an unreliable and potentially compromised network (resolves the problem of Byzantine generals.) Transactions do not need intermediaries and the protocol is open source.

Bitcoin, and in general cryptocurrencies, are an innovative project in constant evolution and change. There is a certain consensus on the potential of cryptocurrency or digital money, auguring a future in which these will become a system of universal exchange. Its technology, blockchain, can solve the security problems posed by decentralized exchanges among equals, and can be applied in many different fields. However, the current cryptocurrencies, the bitcoin between them, raise questions that make them suspicious of fraud
