detailed description

Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a diagram of main steps of a method for processing digital currency according to an embodiment of the present invention. As shown in Figure 1, a method for processing digital currency in the embodiment of the present invention mainly includes:

S101: Receive digital currency operation information sent by the digital currency core system. Digital currency is an encrypted string, and the encrypted string includes the amount of digital currency, the identifier of the issuer, and the identifier of the owner. The digital currency core system is the organization that issues digital currency. Today, the central bank, as the digital currency core system, sends the digital currency operation information to the distributed ledger platform through the message queue for distributed storage. Among them, the operation information includes: issued digital currency, instruction information for destroying digital currency or digital currency map. The issued digital currency is valid digital currency. The instruction information for destroying the digital currency can realize the destruction of the stored digital currency, and when the user verifies the information of the digital currency, it will prompt that the digital currency is invalid. The digital currency graph includes digital currency transaction information, digital currency traceability, and life cycle information.

S102: Parse operation information. The operation information of the digital currency received is the message data sent by the message queue, so after receiving it, the message data is analyzed and operated, and then the operation information of the digital currency can be written into each network node through the distributed ledger technology .

S103: Store the parsed operation information in a database corresponding to each network node. Among them, after analyzing the message data of the operation data of the digital currency, the analyzed information is written into the database corresponding to one of the network nodes. This network node is not unique, and other nodes can also be selected as the first written network node. Then the network node synchronizes the written information to other network nodes, which realizes the consistency of the application databases of each node. The synchronization process can be realized through distributed ledger technology. Through distributed ledger technology, information such as the issuance and destruction of digital currency is recorded on the distributed ledger to ensure the immutability and traceability of currency data. Moreover, the distributed ledger can avoid problems such as the unavailability of a single node, and share the load of verification and confirmation applications by increasing the number of deployed nodes to ensure reachable and reliable services on a global scale. Using distributed ledger technology, it can bear the unbearable access and computing pressure of the centralized system, and provide digital currency related services for the public and individuals. For example, verification, etc.; users can verify digital currency anytime and anywhere through web applications, which is more conducive to the circulation of digital currency in the public.

After the parsed operation information is stored in the database corresponding to each network node, the stored state information is composed into a message queue message; and the message queue message is sent to the digital currency core system. A message queue is a container for data transfer between information systems in computer science, ensuring that messages can be delivered successfully and reliably. In the embodiment of the present invention, message queues may also be used for information interaction with the digital currency core system.

After the above step S103, the operation information of the digital currency stored in each network node can be used, for example, for the verification and confirmation of the digital currency. After receiving the request for verifying the digital currency, the operation information of the corresponding digital currency is searched in the database according to the request, and the verification result is returned after comparison and verification. Furthermore, when the user verifies the authenticity of the digital currency, he will send a verification request through the web application, that is, input the digital currency to be verified into the web application, and the web application will retrieve the corresponding information in the relational database of the nearest network node. If it is retrieved, it will be compared and verified. If it is consistent with the information in the database, the digital currency will be returned as a true verification result, otherwise it will be returned as a false or invalid verification result. And Internet website technology allows users to access the content they need anytime and anywhere under the condition of networking.

Fig. 2 is a sequence diagram of a method for processing digital currency according to an embodiment of the present invention.

In a method for processing digital currency in an embodiment of the present invention, distributed storage is realized by adopting blockchain technology, which is a distributed accounting technology developed in recent years. As shown in Figure 2, the digital currency core system sends digital currency operation information messages (MQ) through the message queue, and the message processing application parses the received messages and writes them into the blockchain. Block chain technology realizes the synchronization of network nodes and updates the corresponding database of network nodes at the same time. After the synchronization is completed, the information of the storage state is composed into a message queue message and fed back to the digital currency core system. Furthermore, the user uses the digital currency verification and confirmation service through the web application.

As shown in FIG. 3 , a digital currency processing system 300 according to an embodiment of the present invention mainly includes: a receiving module 301 , an analyzing module 302 and a storage module 303 . Wherein, the receiving module 301 is used to receive digital currency operation information sent by the digital currency core system, and the operation information includes: issued digital currency, instruction information for destroying digital currency, or digital currency map. If the stored digital currency information is used to verify the authenticity, it only needs to store the valid digital currency stored in the database and the instruction information for destroying the digital currency. The digital currency map can be used for the withdrawal and transaction of digital currency. Wherein, the digital currency is an encrypted string, and the encrypted string includes the amount of the digital currency, the identifier of the issuer, and the identifier of the owner. The parsing module 302 is used to parse the operation information; the storage module 303 is used to distribute and store the parsed operation information in databases corresponding to each network node. Moreover, the storage module 303 writes the parsed information into one of the network nodes; and, through the distributed ledger technology, synchronizes the information written into one of the network nodes to the corresponding databases of other network nodes.

A system 300 for processing digital currency in the embodiment of the present invention also includes a verification module and a feedback module, the verification module is used to receive a request for verifying digital currency, and search the database for the operation information of the corresponding digital currency according to the request, and perform comparison and verification Then return the verification result. The feedback module is used for distributing and storing the parsed operation information in the database corresponding to each network node, and then compose the stored status information into a message queue message; and send the message queue message to the digital currency core system.

In a digital currency processing system according to an embodiment of the present invention, when processing digital currency, the acceptance module receives the message sent by the digital currency core system through the message queue, and then the analysis module processes the message and writes it into the distributed ledger , the distributed ledger synchronizes the operation of digital currency to each network node, and realizes storage during synchronization. Furthermore, end users can verify and confirm the digital currency through the web application. Use the Internet website as the entrance to verify the authenticity of digital currency to facilitate the use of public users. And due to the characteristics of distributed storage, mass users can conduct real-time verification through the terminal, which solves the problem that centralized storage can only conduct digital currency verification for banking institutions and non-bank institutions. Centralized data storage can easily ensure the consistency of data, but it cannot provide services for the general public users. The underlying distributed ledger technology of the present invention adopts a load sharing method while ensuring data reliability. Increase service capacity.
