Cryptocurrency is the latest thing that is gaining the most attention. On the other hand it is based in the new technology is basically, its power is not fully understood. On the other hand, at least in the current form, it fully complements the functions of other, more traditional goods. A typical equity currency model is being developed to study the positive structure of a blockchain-based cryptocurrency system. Model then measured in Bitcoin transaction data to do a scheme quantity test. We do the critical things of a cryptocurrency. A blockchain to store transaction history, distributed updates for details and competitive agreement for such updates. We show that, unlike money, the digital money system does not support fast, final payments.



Since the creation of Bitcoin in 2009, many cryptocurrency cryptocurrencies have been introduced Bitcoin is the most effective. It has been gaining a lot of media attention, as well as its content Market value reached 20 billion USD in March 2017.

Bank of Canada and Mali Singapore official studying its use of payment systems between banks; Deutsche Bundesbank has launched the first blockchain-based payment system for financial assets. Many sponsors believe that cryptocurrency and blockchain technology will be important influence on the future development of payment and financial systems.

Anonymity, Privacy, Confidentiality

Bitcoin exists in a state of incompatibility between anonymity (in the sense that real ownership is not required use the system) and tracking (because everything is recorded in a blockchain, which is public, an irreversible book, as well as a universal book). In practice, the privacy of vanilla Bitcoin comes from a secret. Users can create as many addresses as they like and swap their coins around, until you create each new address in practice. But this paper shows that the "address combination" can be very effective, using a combination of heuristics to put together all the counterfeit controls controlled by a person or business. Anonymity in cryptocurrensets is not just a matter of personal privacy, but also the confidentiality of businesses. Given the strategies to analyze the graph of advanced transactions, without monitoring, the blockchain could not easily disclose cash flow and other financial information.


The future of cryptocurrencies – advantages and disadvantages

There are differing and conflicting theories about the future of cryptocurrencies in general and bitcoins in particular. However, those with libertarian views on life are optimistic and receptive the cryptocurrency system, some authors, economists, and experts from the field are not is enthusiastic about the use of cryptocurency in the payment and financial system transactions.
