Description

a digital currency that conforms to the binary system

Technical field

The present invention relates to the field of Internet technologies, and in particular, to a digital coin conforming to a binary system.

Background technique

Banknotes: commonly known as "money", are familiar to everyone today. There are many inconveniences and disadvantages in banknotes, such as: First, the cost of anti-counterfeiting: banknotes anti-counterfeiting requires a lot of cost in printing, banknote verification and other links. Second, the cost of transportation: cash trucks, escorts, etc. Third, the cost of replacement: easy to be old, damaged, damaged. There are phenomena such as easiness and damage in the circulation of banknotes, and there are cases of damage or burning in the preservation process. Renewed coins need to be reissued regularly to recycle old coins. Fourth, the price of sedimentation: Chinese people love cash, especially in the vast rural areas. A large amount of money is stored in the home, which causes some currencies to be unable to participate in market circulation. The government can only avoid by issuing more money, replenishing banknotes, increasing credit and budget quotas. Deflation This is to say from a certain perspective that banknote sleep also disrupts the stability of currency issuance. V. The disadvantages of anonymity: Because the banknotes do not have the tracking function of the traces of circulation, a large number of bribery and money laundering exist. Sixth, the loss of theft: easy to be stolen or robbed, carrying a lot of banknotes cash is not safe. Not convenient.

Bitcoin: It has been defined by the central bank as “a valuable commodity, not a currency”. Bitcoin has no issuers and is randomly mined. More similar to the original gold mining. It is a primitive form that everyone can mine. The reason why the popularity is worshipped is because the number of bits that can be mined is limited, and there is a limit to the number of plums that can be produced. It is therefore considered as network gold. The bottom layer of Bitcoin is supported by blockchain technology. It is a game for all people mining. The core point is "common witness and mutual trust." The underlying support for this common witness is the blockchain technology. The core of blockchain technology is the decentralized, non-centralized concept of pure interconnection and mutual trust. It is also because of this decentralized "Utopia" characteristic that Bitcoin cannot be called the legal currency of a country. It also makes it difficult to integrate blockchain technology into the banking system of the existing binary system (central bank + commercial bank), and it is even less likely to accept the "Utopia" type of digital currency issuance mechanism realized by blockchain technology. The issuance of digital coins must be controlled by the central bank in an orderly manner and for effective monitoring of the design, issuance, circulation and return of digital coins. Therefore, it can be clearly stated that Bitcoin and even the underlying blockchain technology have congenital defects. trap

Netcoin: such as "Q coins", "game coins", "xx beans", etc., is just a way for a merchant to book their own books, and is equivalent to the website points. From the technical point of view or from the perspective of the distribution mechanism, the currency cannot be equated with the digital currency.

Therefore, there is an urgent need for a technology to achieve "digitalization of banknotes" or to use the technology to issue new forms of digital currency to solve the above technical problems: the ideal digital coin must first conform to the binary architecture of the banking industry, with a clear issuer and It can be controlled for distribution, circulation and recycling. It is advisable in a binary banking system. It can be transferred offline between individuals (C2C). It is payable in commercial consumption (B2C). Real-name holding in the circulation link, real-name signing and signing, tracking traces can be traced, traceable, and analyzable.

Summary of the invention

In the back of the digital coin (coin) Recording the status of the digital currency, the current holder's digital certificate signature, and the registration center's digital signature can provide a replacement certificate for the lost digital currency positive message. The transfer and signing of the digital currency can effectively eliminate problems such as copying, reuse, and theft. The digital currency root is only used in the trusted platform and does not participate in social circulation. Do not leave the trusted platform (unless it is when the currency is returned). In the present invention, the digital currency issuance adopts a "ticket stub certificate" strategy. When the digital currency is issued, one currency number is distributed to two digital currency messages, and one is distributed to the digital currency positive message (for circulation and display on the user side). Another message that is distributed to the back of the digital coin is the digital coin stub (for the transfer of the deposit certificate, which is not included in the circulation on the trusted platform). In the course of the research, the inventors found that digital coins (positive) also experienced loss and damage in the circulation. For example, if the party signing the party sends out the signing, the party may fail to receive the digital currency due to network failure, power failure of the mobile phone, software driver, etc., or the digital currency message received is incomplete. This situation is considered a loss or damage to the digital currency. Since the invention adopts the digital coin stub mechanism, when the digital coin (front side) is damaged, the loss, the loss report, and the evidence are available, and the digital certificate electronic signature has legal effect, and the signing record of the digital currency stub can effectively prove that the Who will replace the new currency.
