Is data center related to digital currency
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

digital currency, based on the characteristics of blockchain, such as decentralization, traceability, non deletion and modification of records, confidentiality, convenient and rapid transaction, can be used as the carrier of asset digitization to a certain extent. Digital currency provides a feasible tool for asset digitization, safe, convenient and transparent transaction

digital currency is illegal in China. In 2017, many ministries and commissions of the state have issued relevant issues, please search online
Relevant national leaders pointed out that blockchain technology is an important breakthrough for independent innovation of core technology. Therefore, more and more attention will be paid to the application of blockchain technology, and the central bank is also studying DCEP, but it is not clear when digital currency will enter the legal application -
a few countries, such as the United States, Japan and Singapore, are tolerant of digital currency:
1) the United States: there are usdt, ETH, and Libra in the future
2) Japan: in April 2017, Japan implemented the revised capital settlement law, stipulating that digital currency and Japanese yen are legal tender and can be traded with each other
3) Singapore: Singapore is tolerant of digital currency, and it has become a common practice for Singaporeans to invest in digital currency< br />
1. Digital currency
digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
features: the use of P2P peer-to-peer network technology to issue, manage and circulate currency theoretically avoids bureaucratic examination and approval, so that everyone has the right to issue currency
Electronic money means that a certain amount of cash or deposit is exchanged from the issuer and the data representing the same amount is obtained. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to our bank card, which is our electronic currencyfeatures:
< UL >e-money and paper money (or physical money) can be easily converted to each other
the data of electronic currency corresponds to the same amount of physical currency
we need to pay physical money to the issuers of e-money (banks and other financial institutions) in order to exchange for the same amount of e-money
3. The similarity between digital currency and electronic currency: both exist in the form of electronic data
The differences between digital currency and electronic currency are as follows:electronic currency has an issuing institution, and the corresponding amount of physical currency in the institution can be exchanged with physical currency; However, digital currency has no specific issuing institution (decentralization) and can only exist in network data
at present, there is no international consensus on whether digital currency is a currency or not, so in China, the main form of digital currency is "investment proct", which is a rather risky investment proct, and only a few businesses are willing to accept digital currency consumption; Of course, some countries (Germany, etc.) have officially recognized the currency status of digital currency
Digital currency can be understood as the digitalization of RMB, which has two obvious advantages: "no account payment" and "no network payment". After Facebook launched Libra this year, the central bank's digital currency has also stepped in. We see both challenges and opportunities
in a word, digital currency is still RMB in fact, but some changes have taken place in its form. We say that digital currency is of great significance. It not only enhances the security and controllability, but also makes counterfeit currency "invisible". In addition, the issuance of the central bank's digital currency is also concive to the central bank's more convenient and transparent management
Digital assets and digital currency are not the same thing
Digital assets refer to the non monetary assets owned or controlled by enterprises or indivials in the form of electronic data and held in daily activities for sale or in the process of proction. The emergence of digital assets benefits from office automation, digital assets rely on the development of electronic payment system, its prospects are predictable2. Digital currency
digital currency refers to the digitization of currency. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature
digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, and that money is virtual. Of course, the virtual money will also have its real value
for example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency
extended data
characteristics of digital assets:
1. High price. Because these application software with special purpose is specially developed for a specific work, its cost is relatively high, and its price is not lower than the price of fixed assets of factory buildings
(2) strong attachment. Application software must be supported by computer hardware and system software in order to play its role3. Strong interaction. Even the simplest application software also has some interactive functions, such as the error prompt to the operator, which is the most basic advantage of IT instry procts
The quantity is infinite. Digital assets as assets are scarce (because not all enterprises or indivials can create digital assets), but its supply can be unlimited. However, tangible assets are always limited e to the limitation of property and storage space Cost decreasing. The proction cost of tangible assets is positively proportional to the proction quantity References:
Network: digital assets

1. The factor of investment supply and demand is actually not independent, and investors' demand for digital currency is also affected by various news factors. However, from the price surge of last year, in the absence of obvious policy and other news, The admission of investors and investment institutions will also promote the price growth
2. Policy factors are also important factors affecting the price of digital red packets. In the past, the implementation and formulation of policies in South Korea, Japan, the United States and China have affected the price trend of bitcoin
3. The real financial factors and the instability of the real financial world make the demand for digital assets rise from time to time. For example, the Chinese government's policy adjustment, the brexit of the UK, the setback of the global stock market at the beginning of 2018 and other events all give play to the hedging characteristics of digital currency
4. Technical factors. Although the security of digital currency has been highly respected in its development, several technical crises still occurred in its development history. For example, bitfinex, the largest bitcoin dollar exchange, was attacked by hackers and stole 120000 bitcoin, and bitcoin fell by 25% in the following six trading days
5. Good news and bad news will affect the fluctuation of currency value
6. The market trend will be affected by the actions of the leading enterprises in this field, platforms, digital currencies with large market share, leaders with great influence in the market, etc
besides, choosing a good project can avoid risks to a certain extent. For example, HNB, the next generation of decentralized blockchain economy, is a reliable project. It relies on the real economy, and at the same time uses value exchange to continuously create endogenous value. It uses blockchain to build an economy, so that everyone can participate in it and get returns through labor, instead of relying on currency speculation.
