The embodiment of the application provides a region-based digital currency using method, as shown in fig. 1, the method may include the following steps:
step S101, after receiving a first payment instruction of digital currency from a payer, changing the owner identification of the digital currency into a user specified by the first payment instruction, and setting or changing the usage area rule of the digital currency into the usage area rule specified by the first payment instruction, thereby obtaining a first target digital currency;
step S102, sending the first target digital currency to the user.
Further, the method may further include:
step S103 (not shown in the figure), after receiving a second payment instruction of the digital currency of the user, verifying whether a usage area of the digital currency corresponding to the second payment instruction meets a usage area rule specified by the first payment instruction;
step S104 (not shown in the figure), if the usage area rule specified by the first payment instruction is met, changing the owner identification of the digital currency into the payee specified by the second payment instruction, and setting the usage area of the digital currency not to be limited by the area rule, thereby obtaining a second target digital currency;
step S105 (not shown in the figure) of sending the second target digital currency to the transferee.
Step S106 (not shown), if the usage area rule specified by the first payment instruction is met, rejecting the payment request.
Wherein the setting or changing of the usage area rule is set according to a smart contract associated with the digital money. Wherein the usage area rule is set by the payer according to a usage attribute of the digital currency and included in the digital currency from the payer. In another embodiment, the setting or changing of the usage area rule is set by the payer in accordance with the usage attribute of the digital money and is included in the digital money from the payer.
Wherein the digital currency is a cryptographic string that includes an amount of the digital currency, an issuer identification, and an owner identification, the cryptographic string further including an intelligent contract identification attribute field that associates the digital currency with the intelligent contract.
Wherein the smart contract includes an identification associating the digital currency with the smart contract. Specifically, to associate digital currency with smart contracts, embodiments of the present invention provide two ways: one is to add a smart contract identification attribute field to the digital currency encryption string through which the digital currency is directly associated with the smart contract. The other method is to add the identification of the digital currency encryption string or the identification of the digital currency transaction characteristics in the intelligent contract, and the digital currency encryption string is specified through the identification of the digital currency encryption string so as to associate the digital currency with the intelligent contract. Digital currency transactions such as payments, smart contracts may be created by identifying particular payment characteristics, such as: payer information, payee information, and thus to the digital currency in which the transaction takes place between all of them.
In addition, digital authentication is used in the process of initiating transaction and running intelligent contracts by digital currency, the basic technology of the digital authentication is to use an asymmetric encryption algorithm to carry out digital signature, and a hash algorithm is used in a signature algorithm.
Specifically, the using method of the area-based digital currency according to the embodiment of the present invention may include two or more using parties, and each of the using parties may initiate an operation of transferring the digital currency to a next using party or a receiving party after receiving the digital currency with usage rules.
For example, fig. 3 is a schematic diagram of expressions and attributes of digital currency according to an embodiment of the present invention, and as shown in fig. 3, the entire character string of the digital currency is encrypted, i.e., the digital currency is represented as an encrypted character string. The attribute of the digital currency is recorded in sub-fields. The fields themselves are scalable and each field is of variable length. The fields may be extended as needed (i.e., application extension). The digital currency encryption string has uniqueness. No part of the digital currency encryption string has regularity.
The attributes of digital currency may include the most basic amount, issuer identification and owner identification. The digital currency contains a unique number (currency number field). The digital currency owner identification may be associated with the real name of the real user. The specific association establishes a correspondence of owner identification to real user by the digital currency system. In the encryption string of digital currency, the owner identification is anonymous, and the background of the digital currency system can realize real name.
Digital currency attributes may include a number of attributes, such as may include currency management attributes, which are a type of field used to support the management of currency issuance currency by currency authorities. The digital currency security attribute is a group of fields related to digital currency security encryption, and can realize the purposes of digital currency non-counterfeiting, non-tampering, non-repudiation, privacy protection, transaction security protection and the like. The digital currency application attribute is a group of fields of the digital currency which meet the requirements of application scenes and value-added services, and can realize functions of controlling fund flow, executing intelligent contracts and the like. Digital currency is a string of encrypted words that identify its owner and amount, representing the currency the owner owns. In a digital money transfer transaction process, the transfer is reflected in the transfer of the owner. After each transaction, the digital currency before the transaction occurred is invalidated, and new digital currency is generated. The old currency before transaction is called the source currency, and the new currency after transaction is called the destination currency. The entire transaction process forms a chain of digital money transfers, thereby enabling digital money traceability. The digital currency background can convert the owner identification into a real user, thereby realizing the anonymous foreground and real-name tracking of the background.
The application attribute field is a group of fields of the digital currency meeting the requirements of application scenes and value-added services, and can realize functions of controlling fund flow, executing intelligent contracts and the like. Wherein the usage area rule of the digital money can be set in the application extension.
In addition, after the RMB is internationalized in the future, the electronic currency of the RMB can also be used as the French currency of other countries, and in order to ensure the currency quantity circulating in the country, the method can realize the control of the use area of the electronic currency. For example, the number of digital currencies in a certain country or region is limited, so that the sudden inrush and inrush of the currencies are avoided, and the effective control of the digital currencies is realized. Illustratively, digital money is set to be usable only in region 1 corresponding to country a, and digital money is not usable in regions of country a other than region 1 or country B, thereby realizing restriction on the region of use of digital money.
The method for using digital currency based on regions in the embodiment of the invention is explained by taking a consumption coupon scene as an example:
the related government departments send the consumption coupons by using funds in the form of digital currency, and set up payment contracts according to the use requirements of the consumption coupons, the payment contracts are automatically executed by a digital currency system, and the digital currency can only enter and exit according to the fund passage defined by the use region rules specified by the payment contracts. The directional payment function ensures that related government departments can independently control the use area of subsequent consumption coupons to achieve the limited area use of digital currency.
The embodiment of the application provides a region-based digital currency using method, after a first payment instruction of digital currency from a payer is received, the owner identification of the digital currency is changed to a user specified by the first payment instruction, and a usage region rule of the digital currency is set or changed to a usage region rule specified by the first payment instruction, so that a first target digital currency is obtained; sending the first target digital currency to the user. The method includes the steps that a rule of using areas of digital currency is set according to a first payment instruction of the digital currency of a payer, so that the using areas of the digital currency can be controlled, supervision on the digital currency is achieved, the digital currency is prevented from flowing into a non-target area to be used, illustratively, the digital currency is set to be used only in an area 1 corresponding to a country A, the digital currency cannot be used in other areas except the area 1 of the country A or a country B, and therefore limitation on the using areas of the digital currency is achieved.
