We need to call the police. This belongs to currency fraud. We can't blindly trust the virtual investment platform that can easily earn a lot of money. Fraud gangs often use "small investment, big income" as t to let investors taste the sweetness first and then increase investment, so as to achieve the purpose of fraud
at present, the so-called "digital currency" in the market is not legal digital currency. The so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud. It is necessary for the general public to raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged
extended information:
five ways to distinguish whether digital currency is MLM currency. Virtual currency does not rely on specific monetary institutions to issue, it is based on a specific algorithm, generated through a large number of calculations, is a decentralized way of issuing. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head
2. Transaction mode. Virtual currency is a kind of sporadic transaction formed spontaneously in the market. After the scale is formed, the third party graally establishes an exchange to complete the transaction. The MLM currency is issued by an institution and traded on its own platform
3. The virtual currency itself is an open source program, maintained in the GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency
Whether the source code link is given. The general decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. What MLM currency focuses on is the transaction process of recharge purchase, not to mention its operation mechanism, and even the website does not have the link address of the source code5. Whether the official website starts with HTTPS. In general, the addresses of the official website and trading website of decentralized digital currency begin with HTTPS. The purpose of this kind of website is to protect users' data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS
According to Caixin, the digital bill trading platform based on blockchain promoted by the central bank has been successfully tested, and the legal digital currency issued by the central bank has been put into trial operation on the platform, and the R & D center will be set up in the near future for continuous improvement; After the Spring Festival, the digital currency Research Institute of the central bank will also be officially listed. This means that in the world, the Central Bank of China will become the first central bank to issue digital currency and carry out real application, and take the lead in exploring the practical application of blockchain. The implementation of the project is a major financial technology achievement led by the central bank and independently innovated and developed. This shows that the people's Bank of China is closely following the international frontier trend of financial technology, striving to grasp the foresight and control of the application of financial technology, and its determination and efforts to explore and practice frontier financial services. The people's Bank of China has said that it will publish digital currency R & D talents on the official Internet, which is of great importance. Here I would like to remind you that the more formal and professional new things are, the more professional talents must be given to operate them

{rrrrrrr}
for example, Internet of things digital currency / national cause (charity) wechat group fraud backbone [Wang Sulan] [Cai Yongming] [Xue gendi] [Du Kaiju] [Liu Yanfei] [Wang Jufang], [Tian Genmin], [Li qiuqiong], [Fu Yunjuan], [sun Qing], [Wang Yanyan], [Qu Fengtao], [Li MEIXIA], [Wu Juzhen], [Lin Baihe], [Li Jianhua], [Xu Tao], [Li Yingchun] and others have painstakingly created [a learning group from Lei Feng], [accurate poverty support and pay group], [b33651 group in ten districts], [Wang Sulan, Cai Yongming new project report group], [Shanghai Learn from Lei Feng core group, work together and help each other group, Shanghai Xue gendi team, learning group (Shanghai), positive energy 605 group, charity 128 group-1, 4 detachment 158 group, 2128 brigade, charity love harmony 87 group, Internet of things 133-9 group, China Internet of things digital currency, 68 District 172 group, Third Bureau, independent special zone of Internet of things, Qian Shuai 16, Li Jianhua, China Internet of things digital currency In order to avoid the attack of network security, we need to change the group name from time to time, and so on. These fraud groups are all advocating various high return projects under the guise of patriotism ([Cai Baiping Asian investment bank project], [169 yuan project], [958 group benefiting the country and the people project (charity enriching Chen Yuying team project)], [charity enriching the people (958 group 51 single) project table 22 yuan, supplementary payment 20 yuan], [2 Yuan Li Yunlong (love) China Chen Yuying foundation project], [10 yuan silver fund fee - 958 group], [Ministry of finance project charity enriching the people Chen Yuying team (100 yuan) project] [18 new projects E-form charity enriching Chen Yuying team on April 9, 2017], [Chen Yuying 200000 Lika project pay 17 yuan - Li qiuqiong], [ABC card 10 yuan silver fund charity enriching Chen Yuying team Jintan Wang Jufang Shanghai Xue gendi team], [State Council's notice and declaration form on the state's welfare for meritorious persons], [State Council's notice and declaration form on the state's welfare for meritorious persons] [3 platform reward form, March 29, 2017], [Dutch crowdfunding project], [International Plum Blossom Association salary payment project], [ease fund settlement fee payment project], [Chinese national welfare fund 60 yuan project], [Guanghua Foundation (20 + 116 yuan) love fund settlement fee payment project], [harmonious home Shanghai team 9.9 yuan project], [China national welfare fund 60 yuan project], [Guanghua Foundation (20 + 116 yuan) love fund settlement fee payment project], [harmonious home Shanghai team 9.9 yuan project] [key meeting card fee for unfreezing national assets of bird's nest on April 25, 2017], [US dollar unfreezing (19667 + Xinbao 170) project], [platform reward fund project], [37 group project of four southwest teams of targeted poverty alleviation], [38 group project of four southwest teams of targeted poverty alleviation], [20 yuan tax paid for 16 yuan Chen Yuying project - 958 group], [investigation on targeted poverty alleviation of General Office of the State Council], [investigation on targeted poverty alleviation of General Office of the State Council] [Ningbo team Ministry of Finance and Red Cross donation project], [218 yuan project], [55 yuan project], [668 yuan project], [1680 yuan project], [35 + 23 yuan project of Sanfeng foundation of guoyuhuan East China Bureau], [Shanghai group of 958 national charity fund members], [20 yuan project of 958 group charity enriching people], [20 yuan project of guoyuhuan East China Bureau] [1000 yuan people's livelihood membership card]... And so on, Semi militarized management was adopted to incite nationalist sentiment. Everyone was required to change the background of their head portraits to red and take formal photos. Moreover, the flag was raised every morning, and activities were held at night when they went to bed. Everyone also had to sing together. In addition, ordinary members are not allowed to talk or pull people into the group at will. All kinds of so-called high return project report documents in the group, brainwashing MP3 lecture recordings of backbone members (such as voice content of CAI Baiping's speech, which was exposed by the Ministry of civil affairs of the people's Republic of China on December 16, 2016 pretending to be vice mayor of Nanjing and national executive president of aiib) (such as propaganda of Qi Lihua 169 project), photos of national leaders of PS presiding over the charity fund distribution meeting All kinds of fake central red head documents emerge one after another. Every night, there are propagandists to organize lectures. In addition to participating in these activities within the group, people in the group also need to sign a letter of commitment, resolutely follow the group leader, make rational use of donations, refuse to buy foreign procts, be willing and bear legal responsibility. In the context of swindlers, the old people are making contributions to the national rejuvenation. Deception not only brings persecution to the victims' families economically, but also some people are stubborn and even threaten to sever their relationship with their close relatives in order to accomplish their "great cause". Very bad nature (similar to MLM brainwashing money)! The consequences are very serious (property lost, family broken)! Extremely corrupt morality (cheating with patriotic feelings)
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good
as for whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that the blockchain technology is an optional technology, but so far, the blockchain still occupies too many resources. Whether it is computing resources or storage resources, it can't cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
in addition, Zhou Xiaochuan also mentioned that there is a lot of discussion about "51% attack" (assuming that indivials have 51% of the computing speed of the whole network, they can realize double payment, reverse transactions, paralyze the whole network, and completely lose the transfer function). More specifically, compared with the special currency, bitcoin does not need the central bank. Zhou Xiaochuan mentioned that for the digital currency controlled by the central bank, a series of technical means, mechanism design and laws and regulations will be adopted to ensure the security of the digital currency operation system, which is different from the design idea of bitcoin from the beginning
as for the digital currency timetable, Zhou Xiaochuan said that there is no established timetable. The relationship between digital currency and cash will be parallel and graally replaced for quite a long time. For reference.
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.
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
extended data:
1. Impact on financial infrastructure
the decentralized mechanism of value exchange based on distributed ledger technology has changed the basic settings of gross and net settlement on which financial market infrastructure depends. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
If digital currency and distributed ledger based technology are widely used, it will bring challenges to the intermediary role of financial system participants, especially banks. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors. Usually, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanismslegal digital currency is the digital currency issued by the state and the central bank in China Strong>
this kind of digital currency can carry on the ordinary on-line mobile payment, also may carry on the sweep code payment, is similar to the Alipay and WeChat's using method, is very convenient.
this new type of legal digital currency is actually much more convenient than the existing means of mobile payment for three reasons:
first, legal digital currency does not need bank transfer and withdrawal Strong>
now we need to use Alipay and WeChat to bind the bank cards on Alipay and WeChat first, then transfer the money in the bank card to Alipay and WeChat, which is very troublesome. p>
but legal digital currency itself is stored in the bank card account, so there is no need to transfer in and withdraw the operation, you can directly withdraw the digital currency on the ATM, or you can directly use the app to pay, which is very convenient
