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.
