Technology used in digital currency
digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)
digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds
Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases{rrrrrrr}
extended information:

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed
Generally speaking, there are not many technologies available for blockchain development. The mainstream development languages are generally divided into the following four types. Different development languages require different timely configuration. You can also visit the blockchain development language selection.
first, go language is selected for development. The high concurrency of go language is very suitable for blockchain development
Secondly, C + + language and C + + technology are mature and fast Thirdly, Java language Four is, node, JSFrom 2015 to 2017, the price of bitcoin increased from more than $100 to $17000, a 100 fold increase. Today, the market value of various numerical currencies is more than 700 billion US dollars. The myth of their benefits is not nonsense
but there are many things behind the chaotic digital currency. You may ask why air currency can be listed on the stock exchange? It's very simple. The exchange also has to charge a part of the fee. Raise the price and then sell it to make money. So the question is, how to identify air currency
first of all, you need to look at the projects behind the digital currency and see what their team background is. Generally speaking, teams without experience in the instry tend to earn money, but how much experience do they have? It is better to be able to participate in the construction of Ethereum and bitstock communities. Such a team is often more reliable. This requires investors to have a certain screening ability to identify good or bad
secondly, there is no way to implement many projects. How can we identify them? In addition to the ability of the team, we also need to see the feasibility, which requires us to systematically learn the knowledge of bitcoin and blockchain. For example, Zhu Jiawei, the COO of fire coin network, learned the blockchain from 0 to 1, and clearly described the development process of bitcoin and blockchain in the form of audio and text. Besides, don Tapscott and Alex Tapscott's "blockchain revolution" are worthy of careful taste P>
moreover, the bubble of digital money is very large nowadays. In the bubble, it is not difficult to make money, but the key is not to be greedy. Long term holding is not good, but it can be operated in a short term. You can make money if you want. However, the key is that people are all profit-making and greed is their nature. Therefore, many people do not accept what they see. They originally made money, but later they lost everything. The gain is not worth the loss. Therefore, it is necessary to control greed
moreover, the development of digital currency is still immature.
first of all, it can be determined that digital RMB can be exchanged for gold and foreign exchange
Digital RMB is only a payment method of legal tender, which is endorsed by the state. The research and application of legal digital currency is concive to meeting the public's demand for legal currency under the condition of intelligent digital economy, improving the convenience, security and anti-counterfeiting level of retail payment, so as to accelerate the development of China's digital economy. It has all the functions of paper money, including the exchange of gold and foreign exchange strong>
At present, the most successful application of blockchain technology is the digital currency represented by bitcoin, and blockchain also benefits from the deeper development of digital currency
instry insiders said that if a wants to send a bitcoin to B, it first needs to send a transaction request to the blockchain network, provide the addresses of a and B as well as the number of bitcoins sent, and at the same time use the private key to digitally sign the sent information to prove its identity to B. After the information is sent, the miner needs to determine the uniqueness of the transaction, the legitimacy of the address involved in the transaction, the authenticity of the digital signature and the correctness of the number of bitcoins after receiving the information sent by A
after successful verification, the transaction will be added to the block, and each block contains all the transactions in the past ten minutes. Generally speaking, each transaction must be confirmed six times before it can be recognized as a legal transaction on the blockchain. Finally, the block is chained, the transaction is completed, and B receives 1 bitcoin
