Digital currency is Freemasonry

1. 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

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.

2. Since 2008, Nakamoto has proposed bitcoin, a peer-to-peer cash trading system. Since then, it has entered the eyes of the world.

the central bank indicated that it has not issued legal digital currency, nor authorized any institutions and enterprises to issue legal digital currency, and there is no promotion team. At present, the so-called "digital currency" in the market is not legal digital currency

The general public should raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

in 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency
