1、 Different definitions:

1. virtual currency:

virtual currency refers to non real currency

digital currency:

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

3. Cryptocurrency:

cryptocurrency is a kind of transaction medium that uses cryptography principles to ensure transaction security and control the creation of transaction units

4. Token (token):

a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English

Second, the characteristics are different:

1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency

2. Digital currency:

is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities

Cryptocurrency:

cryptocurrency is based on the decentralized consensus mechanism, which is opposite to the banking and financial system relying on the centralized regulatory system

4. Token (token):

usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

2. The following points are the characteristics of the blockchain summarized by jinwowo group:

1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network

2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud

3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<

4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information

5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

3. China's digital currency is relatively safe because it is promoted at the national level. According to Li Lihui, head of the blockchain working group of China Internet Finance Association and former president of Bank of China, our country has the largest population in the world, so the scale of our payment market is also the largest in the world. When we issue China's legal digital currency in such a market, we must ensure the reliability and security of digital currency tools in such a high concurrency market. The security of other areas is not necessarily, even if there are audit reports
hope to help you.

4. The central bank does not recognize digital currency
on September 4, the central bank and other seven ministries and commissions issued the notice on preventing the financing risk of token issuance, and the ICO trading platform was completely suspended. After September 14, the relevant token platforms successively removed procts or stopped trading. After the news came out, digital currency was boiling

some people can't help asking: with the collapse of ICO and the closure of bitcoin platform, is digital currency over? Here the central bank gives the answer. The central bank reports that around the Spring Festival this year, the block chain based digital bill trading platform promoted by the central bank has been tested successfully, and the digital currency Research Institute of the central bank will also be officially listed. China's sovereign digital currency will accelerate its arrival. Then some people will question whether China will proce its own bitcoin? Here, let's talk about what is digital currency:

digital currency

digital currency is different from virtual currency, not bitcoin or q-coin! That is to say, it is different from virtual currencies such as bitcoin and Ethernet

virtual currency can only be closed in circulation on the network, just like Tencent's q-coin and Dashen's coin on the platform of Dashen software collaborative instry ecological chain. They can only be used for one use of their own procts. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency. As for legal digital currency, there is no unified international definition. Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, believes that the digital currency researched and issued by the people's Bank of China is indexed RMB. From the perspective of national schemes, it belongs to legal encrypted digital currency, which is not only a payment tool but also a currency. Correspondingly, virtual currency is also called illegal fixed digital currency. Li Lihui, head of the blockchain working group of China Internet Finance Association, once said that digital currency must have legal status, national sovereignty endorsement, and clear responsibility subject of issuance. Virtual currencies represented by bitcoin and ethereal currency have no country, no sovereign endorsement, no qualified issuers, and no national credit support. These are not digital currencies.

5. The biggest feature of blockchain is "decentralization"

6. Public Tianlong% kW public Tianlong

7. Earn. Don't worry.

8. The biggest difference between Chery and other virtual currencies is that the total amount of Chery is very limited and it has a strong scarcity. Investment in Chery is very profitable, large-scale and relatively stable.

9. 1-blockchain can drive the birth of a new business model
the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode
2 - blockchain technology has a flexible architecture
according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions
the openness of 3-chain technology encourages innovation and collaboration
through the opening and cooperation of source code, blockchain technology can promote the cooperation among different developers, researchers and institutions, and learn from each other, so as to achieve a more efficient and secure solution
jinwowo will use blockchain technology to fully record big data sources and improve storage.
