Which digital currency is Shenzhen

1. What are the pilot cities for setting currency? At present, the pilot cities for setting currency are mainly Shanghai, Hangzhou, Guangzhou and Shenzhen

2. In short, virtual currency, also known as cryptocurrency, is issued and circulated on the Internet and mainly traded through exchanges. Because it runs on the blockchain, every transaction on the chain is semi anonymous and tamperable, so it ensures the circulation and a certain degree of security. Mainstream digital currencies include bitcoin, Ethereum and Leyte. digital currency is inseparable from blockchain technology. The core idea of the latter is to ensure that all nodes have a consensus on a transaction through transaction broadcast and irrelevant node confirmation. Once the consensus is formed, transaction confirmation, block excavation and reward will follow. This reward is digital currency. If digital currency wants to have value, it can't do without people's recognition of its value. The more recognition, the more people want to have it, and the exchange came into being. If it's Xiao, it's not recommended to go to big exchanges (currency security, currency, OK) to play contract leverage. You can go to small exchanges to practice, such as currency easy, etc. You can also learn about the coin circle information. The development of the whole coin circle changes every day, very fast
there is no price limit for P.S. digital currency trading, so investment should be cautious!

3. Digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world

the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation

types of digital currency

according to different issuing or consensus mechanisms, it can be divided into four categories:

1, proof of work (POW)

proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk

3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state

4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC

according to the project type, it can also be divided into four categories:

1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin

2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont

3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)

4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.

In early 2014, the Central Bank of China set up a special research group on legal digital currency to demonstrate the feasibility of issuing legal digital currency by the central bank. On January 29, 2017, the central bank officially established the digital currency Research Institute. After the successful development of the prototype of legal digital currency, the digital currency Research Institute of the people's Bank of China has tried to deploy institutions in many parts of the country, and through the integration with R & D institutions and instries, it has achieved the research results of financial development technology. In 2018, the digital currency Research Institute of the people's Bank of China successively settled in Nanjing and Shenzhen. In 2019, the people's Bank of China announced that digital currency will be piloted in Shenzhen, Suzhou, Cheng and xiong'an
