The relationship between digital currency and data structure
several characteristics of digital virtual currency
1, decentralization
2, independent e-wallet
3, open source code
4, measurement and issuance
5, negotiable
investment in virtual currency is now very promising
1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a 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 currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
1、 Different definitions:
1. Electronic currency:
refers to the currency paid by electronic means
2. Digital currency:
is a virtual currency based on node network and digital encryption algorithm
Electronic currency: Based on computer technology, it can be widely used in the fields of proction, exchange, distribution and consumption. It has many functions such as financial savings, credit and non cash settlement2. Digital currency:
e to some open algorithms, digital currency has no issuers, so no one or institution can control its issuance; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
Third, the same point:the circulation mode of e-money and digital money is two-way circulation
extended data
e-money is the virtualization of the value scale of real money and the function of payment means. It is a kind of money without monetary entity. Electronic currency is an invisible currency based on highly developed electronic technology
the value of e-money is transferred from the consumer to the seller through the sales terminal, and then the seller redeems the money. The e-money held by the merchant is sent to the e-money issuer to redeem the money, or to the bank. The bank debits the corresponding amount on its account, and then the bank settles with the issuer through the clearing institution
electronic money can transfer money value directly among the holders. It does not require the intervention of third parties, such as banks. This is also the essential difference between electronic money and traditional cash card and transfer card. p>
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.
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 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
Network: digital currency
when the economy is stable, it doesn't rise. When the economy is in turmoil, people begin to store digital currency. Of course, it is convenient for some corrupt elements
now the economy is stable, the digital currency is in a bear market, the financial crisis, the crisis, and only when there is a crisis can there be an opportunity. At that time, the rapid growth of bitcoin was the opportunity in the financial crisis. Don't worry, there will be a bull market in digital currency, which is expected to come in the second half of next year
There is no relationship between digital currency and Internet of things.
related introction:
the application fields of digital currency and Internet of things are different
1. Internet of things:
through a variety of information sensors, RFID technology, global positioning system, infrared sensors, laser scanners and other devices and technologies
Digital currency:is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
extended data
through various possible network access, the Internet of things realizes the ubiquitous connection between things and people, and realizes the intelligent perception, identification and management of goods and processes. The Internet of things is an information carrier based on the Internet and traditional telecommunication network. It enables all ordinary physical objects that can be independently addressed to form an interconnected network
and digital currency can be considered as a virtual currency based on node network and digital encryption algorithm, which mainly applies fast, economic and secure payment and settlement, establishes digital wallet through digital currency, realizes lower cost and more secure micro payment and capital transfer in areas with insufficient financial coverage and underdeveloped economy, and increases intermediate business income
