in China, the regulations on the administration of RMB stipulates that the proction and sale of token tickets are prohibited. Because there is no clear judicial interpretation of the definition of token ticket, if bitcoin is included in the "token ticket", the legal prospect of bitcoin in China will face uncertainty

The Internet of things in China refers to a network concept in which information sensing devices such as GPS, laser scanners, etc. connect any item with the Internet according to the agreed protocol for information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. The rudiment of the Internet of things is just like the early form of the Internet, local area network, which shows a great prospect
digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
risk
digital gold currency is a form of physical currency, whose deposits are measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value
since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self-regulation way. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports
criticism
digital gold money suppliers and changers have been accused of being intermediaries of fraulent hyip schemes. In January 2006, business week reported that shadowcrew used the e-gold system, involving a large number of online groups whose identity information was stolen. However, the chairman of e-gold claimed that he would not compromise on any criminal activities using e-gold

the school enterprise alliance of Internet of things in China defines the Internet of things as the combination of almost all technologies, computers and Internet technologies, realizing the real-time sharing of environment and state information between objects, as well as intelligent collection, transmission, processing and execution. In a broad sense, the application of information technology can be included in the category of Internet of things, which is the most direct embodiment of the integration of science and technology
digital gold currency is a kind of electronic currency named after the weight of gold. The typical unit of measurement for this currency is the Troy gram or troy ounces, although sometimes the golden Dinar is used. Digital gold currency is funded by gold storage without quota or decentralized quota. By January 2006, digital gold currency suppliers held more than 8.6 metric tons of gold as reserves, worth about $154 million
there is no unified concept of legal digital currency. The Bank of England defines "digital currency" as "a payment method existing only by electronic means... Which can be used to purchase physical goods and services"... Including "private digital currency" and "digital currency issued by the central bank". Further than the Bank of England, Yao Qian, director of the digital currency Research Institute of the people's Bank of China, made clear the multiple connotations of the central bank's legal digital currency in several public speeches: legal and encrypted credit currency, adopted a series of algorithms, and derived more intelligent functions in the payment function
to this end, the central bank has designed a system architecture of "one currency, two warehouses and three centers", that is, taking digital currency as the center, designing the issuing library and deposit library, matching the certification center, big data analysis center and registration center. The central bank's digital currency is issued by the central bank and circulated in the commercial bank's account. The issuing inventory is put into the people's Bank of China to deposit the digital currency. The deposit bank is the database of the commercial bank to deposit the central bank's digital currency. The authentication center manages the identity of institutions and users in a centralized way; The registration center completes the whole life cycle and ownership registration of the central bank's digital currency; The big data analysis center achieves the goals of anti money laundering, anti terrorist financing, index detection and analysis
as an important node in the framework of legal digital currency, commercial banks play an important role in the circulation of central bank's digital currency. In the case that China's non bank payment institutions have occupied a certain market share, it is a better choice for non bank payment institutions to participate in the framework of digital currency operation as a supplement to commercial banks. The reasons are as follows: first, third-party payment institutions can help commercial banks realize the promotion of legal digital currency. Within commercial banks, there is a competitive relationship between legal digital currency and physical currency. The public tends to convert the digital currency in cash account into traditional currency in exchange for income, so it is difficult to achieve the goal of promoting digital currency by commercial banks; Second, the third-party payment institutions can avoid the repeated construction of payment application scenarios by commercial banks. Different from non bank payment institutions, the current payment scenarios of commercial banks are relatively lack of diversification, which will lead to a waste of resources and the rich experience accumulated by non bank payment institutions; Third, the third-party payment institutions can appropriately rece the operating costs of commercial banks. On the one hand, commercial banks need to upgrade the necessary software and hardware for the central bank's digital money service; On the other hand, we should continue to do a good job in traditional RMB deposit and withdrawal services. The simultaneous operation of the two systems will increase a lot of human and material costs. Fourth, the third-party payment institutions can promote the construction of payment instruments and channel integration of commercial banks. In the framework of legal digital currency, the single payment instruments and complex payment channels provided by commercial banks may rece the enthusiasm of the public to use legal digital currency
2 the emergence of legal digital currency reshapes the role of non bank payment institutions
in the process of cooperation with commercial banks, all kinds of non bank payment institutions play four roles. The first is the role of account manager. Non bank payment institutions can not operate deposit and loan business, and the amount in their payment account is not a deposit, so it is easier for the public to accept the role of non bank payment institutions as "digital wallet". At the same time, non bank payment institutions have rich experience in the development and operation of digital currency wallets and their terminals, which is concive to the smooth management and use of central bank's digital currency, and there is no need to worry about the risk of misappropriation of funds by non bank payment institutions. The second is the role of payment service provider. Non bank payment institutions have a lot of experience in scenario development and operation, including mobile payment, cross-border payment and rural payment, and relatively large market share of scenario based payment. On the one hand, powerful non bank payment institutions can develop a variety of procts based on Intelligent legal digital currency to meet the needs of users' exchange, payment, storage and related derivatives; On the other hand, non bank payment institutions can make use of various scenarios to promote the use of legal digital currency. For example, when consumers want to invest through the central bank's digital currency, non bank payment institutions, with the experience of traditional currency investment and payment services and upgraded digital wallet, can be fully competent as the special payment service provider of digital currency investment. Third, the role of system construction service provider. NPC, the core of national payment and settlement system, and CCPC, the core of provincial payment and settlement system, will continue to play an important role in the framework of legal digital currency. In the long-term coexistence of legal digital currency and traditional currency, NPC and CCPC will be double important nodes. Non bank payment institutions with strong technical ability can be used as secondary verification nodes under the framework of legal digital currency to supplement the multi center and distributed system architecture and continue to dock with NPC and CCPC
3 technical connection between non bank payment institutions and legal digital currency system
the innovation of non bank payment institutions is accompanied by the connection with legal digital currency system, covering the whole process of digital currency generation, storage, use and withdrawal. In this process, the first thing to solve is the docking of basic layer technology and transaction mole. The docking of basic layer technology is reflected in three aspects. First, in terms of basic security technology, non bank payment institutions, as providers of mobile terminal transaction forms, need to apply terminal security mole technology, dock with unified encryption and decryption system, provide carriers for secure storage and encryption and decryption operations, and provide effective basic security protection for digital currency. Secondly, in the aspect of data security technology, non bank payment institutions, as a part of the whole payment system, should adopt the official unified ciphertext + MAC / ciphertext + hash technology to transmit digital currency information, so as to ensure the confidentiality, security and non tamperability of the information. Thirdly, in the aspect of transaction security technology, non bank payment institutions, as the advanced nodes participating in bookkeeping, adopt blind signature technology to ensure the controllable anonymity of digital currency in the process of transaction, and eliminate the possibility of repeated payment through serial number, time stamp and other ways; And through encryption and decryption, digital signature, identity authentication and other anti-counterfeiting ways to ensure the authenticity of the transaction
when docking with the transaction mole, non bank payment institutions should do the following: first, docking with the certification center to obtain relevant digital certificates and user identity information; Second, connect with the trusted service management mole to obtain the use function of digital currency; Third, connect with the issuing system and storage system, and apply for and exchange digital currency through the bank treasury; Fourth, connect with the transaction communication mole to ensure that users can realize online payment through the transaction network in the intelligent terminal based on online transaction communication; Fifth, connect with the registration center, notify and record the flow of digital currency transactions, so as to complete the registration of the central bank's digital currency generation, circulation, checking and extinction process
4 scenario docking between non bank payment institutions and legal digital currency system
scenario docking of non bank payment institutions is based on the transformation of their own roles. Legal digital currency is algorithmic currency and intelligent currency, so business innovation and scenario expansion are the proper meaning of legal digital currency system. Non bank payment institutions can achieve scene docking mainly in four aspects
first, enabling the financial instry and defusing the limitations of financial scenario services. At present, there are some limitations in financial scenario service, such as business modeling is not universal, different agents have different management requirements, and the system docking cost of participants is high. Non bank payment institutions connect with the underlying technology of legal digital currency, and through the research and development of smart contract, establish behavior information such as capital flow, trigger conditions, value change rules, revenue right registration, and corresponding capital information (amount, account, currency, etc.) to resolve the existing limitations of financial scenario service. Non bank payment institutions use the atomic properties of digital currency and the atomic transactions of smart contracts to "assemble" into a business model. It does not need to develop a separate platform for different business scenarios, and avoids the monopoly of the instry platform and the non disclosure of information
Second, expand the use scenarios and improve the user experience. Non bank payment institutions can continue to expand the use scenarios according to the characteristics of legal digital currency on the basis of the existing rich payment scenarios, so as to meet the needs of users' exchange, payment, storage and related derivatives. At the same time, through the aggregation application, users can use the app of non bank payment institutions to dock a large number of scenarios and services
thirdly, improve the security of funds and create a universal digital wallet. Non bank payment institutions can provide digital wallet services, create digital wallets that meet security standards through their own technology, and ensure the security of users' funds. Alternative methods include: the central bank and non bank payment institutions cooperate to develop a unified universal digital wallet application, or authorize several qualified non bank payment institutions to provide universal digital wallet services. The digital wallet can realize the mutual exchange between the user's funds in various commercial banks and the legal digital currency even in the self owned accounts of non bank payment institutions. From the perspective of implementation, at the same time, the traditional account system of commercial banks can also bind the digital currency wallet of non bank payment institutions, so as to achieve the joint management of traditional accounts bound with digital currency wallet
Fourth, help cross-border settlement and build a safe and reliable cross time zone alliance chain. Non bank payment institutions can deeply participate in the cross-border payment system of legal digital currency. Cooperation with commercial banks and central banks can be achieved in at least two aspects. First, payment standards and tools are available. Non bank payment institutions participate in the research and establishment of standards and tools to realize the possibility of technical docking. Second, cross border payment system. The business system led by the central bank and participated by commercial banks and qualified non bank payment institutions will help to realize efficient cross-border payment
5 the legal framework of non bank payment institutions and legal digital currency is connected
a perfect legal system is an important guarantee for the operation of the digital currency system. There are several key questions to answer. First, how to determine the ownership of legal digital currency? This is the basis of all legal acts of legal digital currency. The first way of thinking is that legal digital currency is intangible. As a special movable property, it is applicable to the provisions of the property law. For example, Liu Xiangmin, director of the Department of articles and law of the people's Bank of China, believes that "to solve the problem of ownership transfer of digital currency, we should also focus on the publicity of ownership." The second idea is that digital currency is an electromagnetic record, which is applicable to the law of data transfer and transaction. The essence of digital currency is electromagnetic recording, and the transfer of electromagnetic recording content is recorded in the node of digital currency technology architecture. The change of node records is taken as the standard of ownership transfer. Second, how to protect personal information security? Personal information security is a basic problem in the era of digital economy. In addition to legislation to improve the level of technical security, we should also make clear the main types of legal digital currency system
will not be replaced. Another important reason is that as long as one pixel of 3D code is damaged, or the color presents chromatic aberration, it may be unable to read. But now there are many electronic procts, chromaticity is not the same, there will be color difference, so it is difficult to identify. However, the QR code will not have such a situation, sometimes even some damaged information can be read completely, which does not affect the use of . So compared with the two-dimensional code, its practicability is not very strong
Although the idea of collecting patent fees from Chinese people could not be realized, Teng Hongyuan did not attach importance to the invention at the beginning, so Chinese inventors improved the QR code, which also promoted the spread of QR code in China. Three dimensional code is really good, but because both businesses and users are used to two-dimensional code, it is almost impossible for three-dimensional code to replace two-dimensional code in a short time< after all, although 3D code is better than 2D code, 3D code also needs to be swept. So even if 3D code can replace 2D code, it is estimated that it will be many years later. After all, it takes a long time for users to get used to itData RMB has begun to enter people's lives, and digital currency will completely change people's lives in the following aspects:
finally, digital RMB will also facilitate the use of the elderly and other special groups for the elderly and those who exclude the use of intelligent terminals, the central bank should consider more non-contact and passive payment means in digital currency, facilitate the payment and settlement of the group by brushing face, fingerprinting and other means, set certain rules for dection and settlement by taking the settlement account as the child's sub account, so as to facilitate the elderly and provide information to their children at the same time. Similar experience should be not only from the payment link, but also from the perspective of software color, font size and human-computer interaction psychology
